Keeb kwm ntawm txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam Valve (2)

Thawj theem ntawm kev lag luam valve (1949-1959)

01 Npaj los pab txhawb kev rov qab los ntawm kev lag luam hauv tebchaws

Lub sijhawm xyoo 1949 txog 1952 yog lub sijhawm ntawm kuv lub tebchaws kev lag luam rov qab los. Vim qhov kev xav tau ntawm kev tsim kho kev lag luam, lub teb chaws xav tau sai heevli qub, tsis yog xwbtsis tshua muaj siab li qub, tab sis kuj yog ib pawg ntawm siab thiab nruab nrab siab li qub uas tsis tau tsim nyob rau lub sijhawm ntawd. Yuav ua li cas npaj lub valve ntau lawm kom tau raws li qhov xav tau ceev ntawm lub teb chaws yog ib txoj haujlwm hnyav thiab nyuaj.

1. Qhia thiab txhawb kev tsim khoom

Raws li txoj cai ntawm "tsim kev tsim khoom, kev vam meej ntawm kev lag luam, suav nrog rau pej xeem thiab ntiag tug, thiab tau txais txiaj ntsig ntawm kev ua haujlwm thiab peev", cov tib neeg tsoomfwv tau siv txoj hauv kev ua thiab kev txiav txim, thiab txhawb nqa cov lag luam nruab nrab thiab cov lag luam me kom muaj zog. rov qhib thiab tsim cov li qub. Nyob rau hnub ua ntej ntawm kev tsim ntawm Tuam Tshoj Tuam Tshoj, Shenyang Chengfa Iron Factory thaum kawg tau kaw nws txoj kev lag luam vim nws cov nuj nqis hnyav thiab tsis muaj kev lag luam rau nws cov khoom, tsuas yog 7 tus neeg ua haujlwm saib xyuas lub Hoobkas, thiab muag 14 cov cuab yeej siv tshuab los tswj. cov nuj nqis. Tom qab kev tsim ntawm Tuam Tshoj Tshiab, nrog kev txhawb nqa ntawm tsoomfwv cov neeg, lub Hoobkas rov pib tsim khoom, thiab cov neeg ua haujlwm hauv xyoo ntawd tau nce los ntawm 7 txog 96 thaum pib. Tom qab ntawd, lub Hoobkas tau txais cov khoom siv los ntawm Shenyang Hardware Machinery Company, thiab cov khoom tsim tau zoo li tshiab. Tus naj npawb ntawm cov neeg ua haujlwm tau nce mus rau 329, nrog rau cov khoom tsim tawm txhua xyoo ntawm 610 teeb ntawm ntau yam li qub, nrog tus nqi tso tawm ntawm 830,000 yuan. Nyob rau tib lub sijhawm hauv Shanghai, tsis yog tsuas yog cov tuam txhab ntiag tug uas tau tsim cov khoom siv rov qhib dua, tab sis nrog kev rov qab los ntawm kev lag luam hauv lub tebchaws, ntau lub tuam txhab ntiag tug me tau qhib lossis hloov mus rau kev tsim cov li qub, uas ua rau lub koom haum ntawm Kev Tsim Kho Kho Vaj Tse ntawm lub tuam txhab. lub sijhawm ntawd nthuav dav sai.

2. Kev sib koom ua lag luam thiab muag khoom, npaj cov khoom siv valve

Nrog ib tug loj tus naj npawb ntawm cov lag luam ntiag tug tig mus rau hauv valve ntau lawm, tus thawj Shanghai Construction Hardware Association tau ua tsis tau raws li qhov yuav tsum tau ntawm txoj kev loj hlob. Xyoo 1951, Shanghai valve manufacturers tau tsim 6 kev sib koom ua lag luam los ua cov haujlwm ua haujlwm thiab xaj khoom ntawm Shanghai Chaw Muag Khoom Chaw Muag Khoom ntawm Tuam Tshoj Hardware Machinery Company, thiab siv kev sib koom ua lag luam thiab muag khoom. Piv txwv li, Daxin Iron Works, uas lees paub txoj haujlwm ntawm qhov loj nominal qis-siab li qub, thiab Yuanda, Zhongxin, Jinlong thiab Lianggong Machinery Factory, uas lees paub qhov kev tsim cov siab- thiab nruab nrab-siab li qub, tag nrho cov kev txhawb nqa los ntawm Shanghai. Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv Hauv Nroog, Ministry of Industry of East China thiab Central Roj. Raws li kev taw qhia ntawm Petroleum Administration ntawm Ministry of Industry, kev txiav txim ncaj qha raug coj los siv, thiab tom qab ntawd tig mus rau kev txiav txim. Tsoom Fwv Teb Chaws Tsoom Fwv Teb Chaws tau pab cov lag luam ntiag tug kov yeej cov teeb meem hauv kev tsim khoom thiab kev muag khoom los ntawm kev sib koom ua lag luam thiab kev muag khoom txoj cai, pib hloov pauv kev lag luam tsis ncaj ncees ntawm cov lag luam ntiag tug, thiab txhim kho kev txaus siab ntawm cov tswv lag luam thiab cov neeg ua haujlwm, uas tsis tshua muaj kev cuam tshuam hauv kev siv tshuab, khoom siv. thiab cov xwm txheej hauv lub Hoobkas Raws li qhov xwm txheej, nws tau muab ntau cov khoom siv valve rau cov lag luam tseem ceeb xws li cov chaw tsim hluav taws xob, cov nroj tsuag steel thiab cov roj av kom rov pib tsim khoom.

3. Kev txhim kho rau kev kho dua tshiab ntawm kev pabcuam kev lag luam hauv tebchaws

Hauv thawj tsib xyoos txoj kev npaj, lub xeev tau txheeb xyuas 156 txoj haujlwm tseem ceeb ntawm kev tsim kho, ntawm qhov kev tsim kho ntawm Yumen Oil Field thiab Anshan Iron thiab Steel Company qhov kev tsim khoom yog ob txoj haujlwm loj. Txhawm rau rov pib tsim khoom hauv Yumen Oilfield kom sai li sai tau, Petroleum Administration Bureau ntawm Ministry of Fuel Industry tau teeb tsa cov khoom siv roj av hauv Shanghai. Shanghai Jinlong Hardware Factory thiab lwm tus tau ua txoj haujlwm ntawm kev sim-tsim ib pawg ntawm nruab nrab-siab steel li qub. Nws yog qhov xav kom xav txog qhov nyuaj ntawm kev sim-ua qhov nruab nrab-siab li qub los ntawm cov chaw ua haujlwm me me-style. Qee hom tsuas yog tuaj yeem ua raws li cov qauv muab los ntawm cov neeg siv khoom, thiab cov khoom tiag raug tshawb xyuas thiab kos duab. Txij li thaum qhov zoo ntawm cov hlau castings tsis zoo txaus, tus thawj cam khwb cia steel valve lub cev yuav tsum tau hloov mus rau forgings. Thaum lub sij hawm ntawd, tsis muaj qhov drilling tuag rau oblique qhov ua ntawm lub ntiaj teb valve lub cev, yog li nws tsuas yog yuav tsum tau drilled ntawm tes, thiab ces kho los ntawm ib tug fitter. Tom qab kov yeej ntau yam teeb meem, peb thaum kawg tau ua tiav hauv kev sim ntau lawm ntawm NPS3 / 8 ~ NPS2 nruab nrab-siab steel rooj vag li qub thiab lub ntiaj teb li qub, uas tau txais txiaj ntsig zoo los ntawm cov neeg siv khoom. Nyob rau hauv lub thib ob ib nrab ntawm xyoo 1952, Shanghai Yuanta, Zhongxin, Weiye, Lianggong thiab lwm yam factories tau ua hauj lwm ntawm kev sim ntau lawm thiab loj zus tau tej cov cam khwb cia steel li qub rau roj av. Thaum lub sij hawm ntawd, Soviet designs thiab qauv tau siv, thiab cov kws kho mob tau kawm los ntawm kev ua, thiab kov yeej ntau yam teeb meem hauv kev tsim khoom. Kev sim ntau lawm ntawm Shanghai cam khwb cia steel li qub tau teeb tsa los ntawm Ministry of Petroleum, thiab kuj tau txais kev koom tes ntawm ntau lub Hoobkas hauv Shanghai. Asia Hoobkas (tam sim no Shanghai Tshuab Kho Hoobkas) muab steel castings uas ua tau raws li qhov yuav tsum tau, thiab Sifang Boiler Factory pab hauv blasting. Qhov kev sim thaum kawg tau ua tiav nyob rau hauv kev sim ntau lawm ntawm cov cam khwb cia steel valve qauv, thiab tam sim ntawd npaj loj ntau lawm thiab xa mus rau Yumen Oilfield siv raws sij hawm. Tib lub sijhawm, Shenyang Chengfa Iron Works thiab Shanghai Daxin Iron Works kuj tau muablow-pressure li qubnrog rau qhov loj nominal ntau thiab tsawg rau cov chaw tsim hluav taws xob, Anshan Iron thiab Steel Company kom rov pib tsim khoom thiab kev tsim kho hauv nroog.

Thaum lub sij hawm rov qab los ntawm lub teb chaws kev lag luam, kuv lub teb chaws txoj kev lag luam valve tau tsim sai heev. Nyob rau hauv 1949, lub valve tso zis tsuas yog 387t, uas tau nce mus rau 1015t nyob rau hauv 1952. Technically, nws tau muaj peev xwm tsim cam khwb cia steel li qub thiab tsis tshua muaj siab loj li qub, uas tsis tsuas yog muab txuam li qub rau kev rov qab los ntawm lub teb chaws kev lag luam, tab sis kuj nteg lub hauv paus zoo rau kev txhim kho yav tom ntej ntawm Tuam Tshoj txoj kev lag luam valve.

02 Kev lag luam valve pib

Xyoo 1953, kuv lub teb chaws tau pib nws thawj tsib xyoos txoj kev npaj, thiab kev lag luam xws li roj av, tshuaj lom neeg kev lag luam, metallurgy, hluav taws xob fais fab thiab thee tag nrho ua rau kev loj hlob sai. Lub sijhawm no, qhov xav tau ntawm cov li qub tau muab ntau ntxiv. Thaum lub sijhawm ntawd, txawm hais tias muaj ntau lub chaw tsim khoom me me uas tsim tawm, lawv cov kev siv zog tsis muaj zog, lawv cov cuab yeej siv tau dhau los, lawv cov chaw ua haujlwm tau yooj yim, lawv cov nplai me me dhau, thiab lawv tawg heev. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm kev loj hlob sai ntawm kev lag luam hauv lub tebchaws, Thawj Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam Machinery (hu ua thawj Ministry of Machinery) txuas ntxiv txhim kho thiab hloov pauv cov tuam txhab ntiag tug qub thiab nthuav dav valve ntau lawm. Nyob rau tib lub sijhawm, muaj cov phiaj xwm thiab cov kauj ruam los tsim cov pob txha thiab cov qhov tseem ceeb. Kev lag luam, kuv lub teb chaws valve kev lag luam pib pib.

1. Lub reorganization ntawm theem nrab valve kev lag luam nyob rau hauv Shanghai

Tom qab kev tsim ntawm Tuam Tshoj Tshiab, Party tau siv txoj cai ntawm "kev siv, kev txwv thiab kev hloov pauv" rau kev lag luam peev thiab kev lag luam.

Nws muab tawm tias muaj 60 lossis 70 lub chaw ua haujlwm me me hauv Shanghai. Qhov loj tshaj ntawm cov factories no tsuas muaj 20 mus rau 30 tus neeg, thiab qhov tsawg tshaj plaws tsuas muaj ob peb tus neeg. Txawm hais tias cov tuam txhab valve no tsim cov li qub, lawv cov thev naus laus zis thiab kev tswj hwm rov qab zoo heev, cov cuab yeej siv thiab cov tsev tsim khoom siv tau yooj yim, thiab cov txheej txheem tsim tau yooj yim. Qee tus tsuas muaj ib lossis ob lub tshuab dhos yooj yim lossis siv lub tshuab siv, thiab tsuas muaj qee qhov cub hluav taws xob rau casting, feem ntau yog siv manually. , tsis muaj peev xwm tsim thiab kuaj cov khoom siv. Qhov xwm txheej no tsis tsim nyog rau kev tsim khoom niaj hnub no, thiab tsis tuaj yeem ua tau raws li cov kev xav tau ntawm lub xeev, thiab nws tsis tuaj yeem tswj xyuas qhov zoo ntawm cov khoom valve. Txog qhov kawg no, Tsoom Fwv Nroog Shanghai tau tsim kev koom tes nrog cov tuam txhab valve hauv Shanghai, thiab tsim Shanghai Pipeline Switches No. 1, No. 2, No. 3, No. 4, No. 5, No. 6 thiab lwm yam. Central lag luam. Ua ke cov saum toj no, centralized tswj nyob rau hauv cov nqe lus ntawm technology thiab zoo, uas ua tau zoo unifies lub tawg khiav ri niab thiab chaotic kev tswj, yog li zoo heev mobilizing lub siab nyiam ntawm feem coob ntawm cov neeg ua hauj lwm los tsim socialism, qhov no yog thawj qhov tseem ceeb reorganization ntawm lub valve kev lag luam.

Tom qab kev koom tes nrog pej xeem thiab ntiag tug hauv xyoo 1956, kev lag luam valve hauv Shanghai tau hloov kho thib ob thiab kev tsim kho tshiab ntawm kev lag luam loj, thiab cov tuam txhab kev lag luam xws li Shanghai Construction Hardware Company, Petroleum Machinery Parts Manufacturing Company thiab General Machinery Company tau tsim. Lub tuam txhab valve pib koom nrog kev tsim kho kho vajtse tau tsim Yuanda, Rongfa, Zhongxin, Weiye, Jinlong, Zhao Yongda, Tongxin, Fuchang, Wang Yingqi, Yunchang, Dehe, Jinfa, thiab Xie los ntawm cheeb tsam. Muaj txog 20 lub hauv paus chaw tsim khoom hauv Dalian, Yuchang, Deda, thiab lwm yam. Txhua lub Hoobkas hauv nruab nrab muaj ntau lub chaw tsim hluav taws xob nyob rau hauv nws txoj cai. Ib pawg neeg sab nrauv thiab cov hauv paus hauv paus koom ua haujlwm sib koom ua haujlwm tau tsim nyob rau hauv cov nroj tsuag hauv nruab nrab. Tsoomfwv tau muab cov neeg sawv cev rau pej xeem los ua tus thawj tswj hwm kev tswj hwm, thiab tau tsim cov khoom tsim khoom, muab khoom, thiab cov koom haum kev lag luam nyiaj txiag, thiab maj mam siv cov kev tswj xyuas zoo ib yam li cov tuam txhab lag luam hauv xeev. Tib lub sijhawm, thaj chaw Shenyang kuj tau koom ua ke 21 lub chaw tsim khoom me me rau hauv ChengfaRooj vag ValveHoobkas. Txij thaum ntawd los, lub xeev tau coj cov khoom lag luam me thiab nruab nrab mus rau hauv lub teb chaws txoj kev npaj taug qab los ntawm cov koom haum tswj hwm txhua qib, thiab tau npaj thiab tsim cov khoom siv valve. Qhov no yog ib qho kev hloov pauv hauv kev tswj hwm kev lag luam valve txij li kev tsim ntawm Tuam Tshoj Tshiab.

2. Shenyang General Machinery Factory hloov mus rau valve ntau lawm

Nyob rau tib lub sij hawm raws li reorganization ntawm valve manufacturers nyob rau hauv Shanghai, Thawj Machinery Department tau faib cov khoom ntawm txhua lub koom haum ncaj qha koom nrog, thiab qhia meej txog cov kws tshaj lij kev coj ua ntawm cov chaw tsim khoom ncaj qha thiab cov chaw tsim khoom loj hauv lub xeev. Shenyang General Machinery Factory tau hloov dua siab tshiab rau hauv cov chaw tsim khoom valve. kev lag luam. Tus thawj ntawm lub Hoobkas yog bureaucratic peev tuam txhab loj chaw ua haujlwm thiab Japanese pseudo-kev lag luam Dechang Hoobkas. Tom qab kev tsim ntawm Tuam Tshoj Tshiab, lub Hoobkas tsuas yog tsim ntau yam cuab yeej siv tshuab thiab cov yeeb nkab txuas. Xyoo 1953, nws pib tsim cov tshuab ua haujlwm ntoo. Xyoo 1954, thaum nws tau ncaj qha los ntawm kev tswj hwm ntawm Thawj Lub Tsev Haujlwm Saib Xyuas Kev Ua Haujlwm, nws muaj 1,585 tus neeg ua haujlwm thiab 147 pawg ntawm ntau yam tshuab thiab khoom siv. Thiab nws muaj peev xwm ntau lawm ntawm cam khwb cia hlau, thiab lub zog technical yog kuj muaj zog. Txij li thaum xyoo 1955, txhawm rau hloov mus rau kev txhim kho ntawm lub teb chaws txoj kev npaj, nws tau hloov pauv mus rau qhov kev tsim tawm ntawm lub valve, rov tsim kho qhov qub hlau ua haujlwm, sib dhos, cov cuab yeej, kev kho tshuab thiab kev cob qhia steel casting, ua ib lub riveting thiab vuam rhiav, thiab tsim ib tug tshiab riveting. Central Laboratory thiab chaw kuaj xyuas metrological. Qee cov kws tshaj lij raug xa mus los ntawm Shenyang Pump Factory. Xyoo 1956, 837ttsis tshua muaj siab li qubtau tsim, thiab loj ntau lawm ntawm siab thiab nruab nrab siab li qub tau pib. Xyoo 1959, 4213t ntawm li qub tau tsim, suav nrog 1291t ntawm qhov siab thiab nruab nrab siab li qub. Xyoo 1962, nws tau hloov npe hu ua Shenyang High thiab Nruab Nrab Siab Siab Valve Hoobkas thiab tau los ua ib lub tuam txhab loj tshaj plaws hauv kev lag luam valve.

3. Thawj qhov kawg ntawm valve ntau lawm

Nyob rau hauv thaum ntxov hnub ntawm kev tsim ntawm Tuam Tshoj Tshiab, kuv lub teb chaws lub valve ntau lawm mas daws tau los ntawm kev koom tes thiab kev sib ntaus sib tua. Nyob rau lub sijhawm "Great Leap Forward", kuv lub teb chaws txoj kev lag luam valve tau ntsib nws thawj qhov kawg ntawm kev tsim khoom. Valve tso zis: 387t hauv 1949, 8126t hauv xyoo 1956, 49746t hauv xyoo 1959, 128.5 npaug ntawm xyoo 1949, thiab 6.1 npaug ntawm xyoo 1956 thaum kev koom tes nrog pej xeem thiab ntiag tug tau tsim. Kev tsim cov siab thiab nruab nrab siab li qub tau pib lig, thiab kev tsim khoom loj tau pib xyoo 1956, nrog rau txhua xyoo tso tawm ntawm 175t. Nyob rau hauv 1959, cov zis tau mus txog 1799t, uas yog 10.3 npaug ntawm xyoo 1956. Txoj kev loj hlob sai ntawm kev tsim kho kev lag luam hauv lub tebchaws tau txhawb txoj kev loj hlob ntawm kev lag luam valve. Xyoo 1955, Shanghai Lianggong Valve Hoobkas tau ua tiav kev sim-tsim Christmas tsob ntoo valve rau Yumen Oilfield; Shanghai Yuanda, Zhongxin, Weiye, Rongfa thiab lwm yam tshuab factories sim-tsim cam khwb cia hlau, forged steel nruab nrab thiab siab siab li qub thiab nominal siab rau roj teb thiab chiv nroj tsuag High-pressure chiv li qub ntawm PN160 thiab PN320; Shenyang General Machinery Factory thiab Suzhou Iron Factory (tus thawj coj ntawm Suzhou Valve Factory) tau ua tiav kev sim siab-tsim li qub rau Jilin Chemical Industry Corporation's fertilizer Hoobkas; Shenyang Chengfa Iron Factory tau ua tiav kev sim-tsim lub rooj vag hluav taws xob nrog lub npe loj ntawm DN3000. Nws yog lub valve loj tshaj plaws thiab hnyav tshaj plaws hauv Suav teb thaum lub sijhawm ntawd; Shenyang General Machinery Factory tau ua tiav kev sim ua tiav cov khoom siv siab siab siab nrog cov nominal qhov ntau thiab tsawg ntawm DN3 ~ DN10 thiab nominal pressures ntawm PN1500 ~ PN2000 rau high-pressure polyethylene intermediate test device; Shanghai Daxin Hlau Factory tsim rau kev lag luam metallurgical Lub siab kub cua kub valve nrog lub npe loj ntawm DN600 thiab flue valve ntawm DN900; Dalian Valve Factory, Wafangdian Valve Factory, thiab lwm yam kuj tau ua tiav kev loj hlob sai. Kev nce ntau thiab ntau ntawm cov li qub tau txhawb txoj kev loj hlob ntawm kev lag luam valve. Tshwj xeeb tshaj yog nrog kev tsim kho kev xav tau ntawm kev lag luam "Great Leap Forward" kev lag luam, cov chaw tsim khoom me me thiab nruab nrab ntawm lub valve tau tshwm sim thoob plaws lub tebchaws. Los ntawm 1958, lub teb chaws valve ntau lawm tuam txhab muaj ze li ntawm ib puas, tsim ib tug loj loj valve ntau lawm pab neeg. Nyob rau hauv 1958, tag nrho cov zis ntawm li qub tau nce mus rau 24,163t, nce 80% tshaj 1957; Thaum lub sij hawm no, kuv lub teb chaws lub valve ntau lawm muaj nws thawj climax. Txawm li cas los xij, vim qhov kev tso tawm ntawm cov tuam txhab valve, nws kuj coj teeb meem ntau. Piv txwv li: tsuas yog nrhiav kom muaj nuj nqis, tsis zoo; "ua me me thiab ua loj, hauv zos txoj kev", tsis muaj kev siv tshuab; tsim thaum ua, tsis muaj cov tswv yim txheem; luam thiab luam tawm, ua rau kev tsis meej pem. Vim lawv txoj cai sib cais, txhua tus muaj cov txheej txheem sib txawv. Lub ntsiab lus ntawm li qub tsis zoo ib yam nyob rau hauv ntau qhov chaw, thiab lub nominal siab thiab nominal loj series tsis sib xws. Qee lub tuam txhab xa mus rau cov qauv Soviet, qee qhov xa mus rau cov qauv Japanese, thiab qee qhov xa mus rau Asmeskas thiab Askiv cov qauv. Tsis meej pem heev. Nyob rau hauv cov nqe lus ntawm ntau yam, specifications, kev twb kev txuas qhov ntev, cov yam ntxwv ntev, kev xeem tej yam kev mob, xeem qauv, xim cim, lub cev thiab tshuaj, thiab kev ntsuas, thiab lwm yam. Muaj ntau lub tuam txhab txais yuav ib qho kev sib piv txoj kev "sib npaug rau lub rooj zaum", qhov zoo. tsis tau lees tias, cov zis tsis tau nce, thiab cov txiaj ntsig kev lag luam tsis zoo tuaj. Qhov xwm txheej ntawm lub sijhawm ntawd yog "sib cais, chaotic, ob peb, thiab tsawg", uas yog, valve factories tau tawg mus rau txhua qhov chaw, chaotic tswj system, tsis muaj kev sib koom ua ke cov qauv thiab specifications, thiab cov khoom tsis zoo. Txhawm rau thim qhov xwm txheej no, lub xeev tau txiav txim siab los npaj cov neeg ua haujlwm cuam tshuam los ua ib qho kev tshawb fawb hauv lub tebchawslub valvekev lag luam.

4. Thawj lub teb chaws valve ntau lawm daim ntawv ntsuam xyuas

Txhawm rau kom paub qhov xwm txheej ntawm cov khoom siv valve, xyoo 1958, Thawj thiab Peb Lub Chaw Haujlwm ntawm Thawj Lub Tuam Txhab Machinery tau teeb tsa lub teb chaws valve ntau lawm daim ntawv ntsuam xyuas. Pab neeg tshawb xyuas tau mus rau 4 cheeb tsam thiab 24 lub nroog hauv Northeast Tuam Tshoj, North China, East Tuam Tshoj thiab Central South Tuam Tshoj los ua kev tshawb fawb dav dav ntawm 90 lub tuam txhab valve. Qhov no yog thawj lub teb chaws valve daim ntawv ntsuam xyuas txij li thaum nrhiav tau ntawm cov neeg koom pheej ntawm Tuam Tshoj. Lub sijhawm ntawd, kev tshawb fawb tau tsom mus rau cov tuam txhab valve nrog cov nplai loj dua thiab ntau hom thiab cov lus qhia tshwj xeeb, xws li Shenyang General Machinery Factory, Shenyang Chengfa Iron Factory, Suzhou Iron Factory, thiab Dalian Valve. Factory, Beijing Hardware Material Factory (predecessor of Beijing Valve Factory), Wafangdian Valve Factory, Chongqing Valve Factory, ntau lub tuam txhab valve hauv Shanghai thiab Shanghai Pipeline Hloov 1, 2, 3, 4, 5 thiab 6 factories, thiab lwm yam.

Los ntawm kev tshawb nrhiav, cov teeb meem tseem ceeb uas muaj nyob rau hauv kev tsim tawm valve tau pib pom:

1) Tsis muaj kev npaj tag nrho thiab kev faib ua haujlwm tsim nyog, ua rau rov ua dua thiab cuam tshuam rau lub peev xwm ntau lawm.

2) Cov qauv khoom valve tsis sib koom ua ke, uas tau ua rau muaj kev cuam tshuam loj rau cov neeg siv kev xaiv thiab kev saib xyuas.

3) Lub hauv paus ntawm kev ntsuas thiab tshuaj xyuas kev ua haujlwm yog qhov tsis zoo, thiab nws yog qhov nyuaj los xyuas kom meej qhov zoo ntawm cov khoom valve thiab ntau lawm.

Hauv kev teb rau cov teeb meem saum toj no, pab pawg tshawb xyuas tau muab peb txoj kev ntsuas rau cov haujlwm thiab cov chaw ua haujlwm, suav nrog kev txhawb nqa tag nrho cov phiaj xwm, kev faib tawm ntawm kev ua haujlwm, thiab kev tsim khoom thiab muag khoom sib npaug; ntxiv dag zog rau standardization thiab lub cev thiab tshuaj ntsuam xyuas ua hauj lwm, tsim unified valve qauv; thiab ua kev tshawb nrhiav kev sim. 1. Cov thawj coj ntawm Lub Chaw Haujlwm 3rd tau txuas nrog qhov tseem ceeb ntawm qhov no. Ua ntej tshaj plaws, lawv tau tsom mus rau kev ua haujlwm ntawm tus qauv. Lawv tau tso siab rau Machinery Manufacturing Technology Research Institute ntawm Thawj Lub Tsev Haujlwm Saib Xyuas Kev Ua Haujlwm los npaj cov tuam txhab tsim khoom lag luam los tsim cov qauv kev tsim cov raj xa dej, uas tau ua tiav hauv kev lag luam hauv xyoo 1961. Txhawm rau coj lub valve tsim ntawm txhua lub Hoobkas, lub koom haum tau sau thiab luam tawm "Valve Design Manual". Cov khoom siv hluav taws xob cov qauv tsim tawm los ntawm Ministry yog thawj pawg ntawm cov qauv valve hauv kuv lub tebchaws, thiab "Valve Design Manual" yog thawj lub valve tsim cov ntaub ntawv tsim tawm los ntawm peb tus kheej, uas tau ua lub luag haujlwm zoo hauv kev txhim kho qib tsim ntawm valve. cov khoom hauv kuv lub tebchaws. Los ntawm qhov kev tshawb fawb thoob ntiaj teb no, qhov tseem ceeb ntawm txoj kev loj hlob ntawm kuv lub teb chaws valve kev lag luam nyob rau hauv 10 xyoo dhau los tau pom tawm, thiab cov tswv yim thiab cov kev ntsuas tau raug coj mus rau tag nrho tshem tawm ntawm chaotic imitation ntawm valve ntau lawm thiab tsis muaj cov qauv. Kev tsim khoom siv thev naus laus zis tau ua ib kauj ruam loj rau pem hauv ntej thiab pib nkag mus rau theem tshiab ntawm tus kheej tsim thiab lub koom haum ntawm kev tsim khoom loj.

03 Cov ntsiab lus

Los ntawm 1949 txog 1959, kuv lub teb chawsvalvekev lag luam sai sai rov qab los ntawm kev ntxhov siab ntawm Tuam Tshoj qub thiab pib pib; los ntawm kev saib xyuas, imitation rau tus kheej tsimdkos npe thiab tsim khoom, los ntawm kev tsim cov khoom siv qis qis rau kev tsim cov siab thiab nruab nrab siab li qub, pib tsim lub valve manufacturing kev lag luam.
