01 Npaj kom pab txhawb kev rov qab los ntawm lub teb chaws kev lag luam

Lub sijhawm txij li xyoo 1949 txog 1952 yog lub sijhawm uas kuv lub tebchaws tau rov qab los ntawm kev lag luam. Vim yog qhov xav tau ntawm kev tsim kho kev lag luam, lub tebchaws xav tau ntau tus neeg sai saicov li qub, tsis yog tsuas yogcov twj tso kua mis siab qis, tab sis kuj yog ib pawg ntawm cov twj tso kua siab thiab nruab nrab uas tsis tau tsim tawm thaum lub sijhawm ntawd. Yuav ua li cas los npaj cov khoom siv twj kom tau raws li qhov xav tau ceev ntawm lub tebchaws yog ib txoj haujlwm hnyav thiab nyuaj.

1. Qhia thiab txhawb nqa kev tsim khoom

Raws li txoj cai ntawm "kev tsim khoom, kev vam meej ntawm kev lag luam, kev xav txog pej xeem thiab ntiag tug, thiab pab txhawb nqa ob qho tib si kev ua haujlwm thiab peev", tsoomfwv cov pej xeem tau txais txoj hauv kev ua thiab kev txiav txim, thiab txhawb nqa cov lag luam nruab nrab thiab me me kom rov qhib thiab tsim cov li qub. Nyob rau hmo ua ntej kev tsim tsa ntawm Lub Tebchaws Suav, Shenyang Chengfa Hlau Hoobkas thaum kawg kaw nws txoj kev lag luam vim nws cov nuj nqis hnyav thiab tsis muaj kev ua lag luam rau nws cov khoom, tsuas yog tso 7 tus neeg ua haujlwm los saib xyuas lub Hoobkas, thiab muag 14 lub tshuab cuab yeej los tswj cov nuj nqis. Tom qab kev tsim tsa ntawm Tuam Tshoj Tshiab, nrog kev txhawb nqa ntawm tsoomfwv cov pej xeem, lub Hoobkas rov pib tsim khoom, thiab tus lej ntawm cov neeg ua haujlwm hauv xyoo ntawd tau nce los ntawm 7 mus rau 96 thaum nws pib. Tom qab ntawd, lub Hoobkas tau txais cov khoom siv los ntawm Shenyang Hardware Machinery Company, thiab kev tsim khoom tau coj mus rau qhov tshiab. Tus lej ntawm cov neeg ua haujlwm tau nce mus rau 329, nrog rau cov khoom tsim tawm txhua xyoo ntawm 610 pawg ntawm ntau yam li qub, nrog rau tus nqi tso tawm ntawm 830,000 yuan. Nyob rau tib lub sijhawm hauv Shanghai, tsis yog tsuas yog cov lag luam ntiag tug uas tau tsim cov li qub rov qhib dua, tab sis nrog kev rov zoo ntawm lub teb chaws kev lag luam, ntau lub lag luam me me ntiag tug tau qhib lossis hloov mus rau kev tsim cov li qub, uas ua rau lub koom haum ntawm Lub Koom Haum Kho Vaj Tse thaum lub sijhawm ntawd nthuav dav sai.

2. Kev yuav khoom thiab kev muag khoom ua ke, npaj cov khoom siv valve

Muaj ntau lub tuam txhab lag luam ntiag tug uas tig mus ua cov khoom siv valve, lub koom haum Shanghai Construction Hardware Association thawj zaug tsis tau ua raws li qhov yuav tsum tau ua ntawm kev txhim kho. Xyoo 1951, cov chaw tsim khoom valve hauv Shanghai tau tsim 6 lub koom haum sib koom tes los ua cov haujlwm ua thiab xaj khoom ntawm Shanghai Purchasing Supply Station ntawm Tuam Txhab Tshuab Kho Vaj Khoom Siv Tuam Txhab ... Tsoomfwv Tib Neeg 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 ke ntawm txoj cai yuav khoom thiab kev muag khoom, thawj zaug hloov pauv kev lag luam tsis muaj kev vam meej ntawm cov lag luam ntiag tug, thiab txhim kho kev txaus siab rau kev tsim khoom ntawm cov tswv lag luam thiab cov neeg ua haujlwm, uas tsis tshua muaj kev siv tshuab, khoom siv thiab cov xwm txheej hauv Hoobkas. Hauv qab qhov xwm txheej, nws tau muab ntau yam khoom siv valve rau cov lag luam tseem ceeb xws li cov chaw tsim hluav taws xob, cov chaw tsim hlau thiab cov chaw roj kom rov pib tsim khoom.

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

Hauv thawj tsib xyoos txoj kev npaj, lub xeev tau txheeb xyuas 156 qhov project tseem ceeb, uas yog kev kho dua tshiab ntawm Yumen Oil Field thiab Anshan Iron and Steel Company cov khoom tsim tawm yog ob qhov project loj. Yuav kom rov pib tsim khoom hauv Yumen Oilfield sai li sai tau, Lub Chaw Haujlwm Saib Xyuas Roj Av ntawm Ministry of Fuel Industry tau teeb tsa kev tsim cov khoom siv roj av hauv Shanghai. Shanghai Jinlong Hardware Factory thiab lwm tus tau ua txoj haujlwm sim-tsim cov khoom siv hlau nruab nrab. Nws yog qhov ua tau los xav txog qhov nyuaj ntawm kev sim-tsim cov khoom siv hlau nruab nrab los ntawm cov chaw ua haujlwm me me. Qee hom tsuas yog tuaj yeem ua raws li cov qauv uas cov neeg siv muab, thiab cov khoom tiag tiag raug soj ntsuam thiab kos duab. Vim tias qhov zoo ntawm cov hlau castings tsis zoo txaus, lub cev hlau cam khwb cia thawj zaug yuav tsum tau hloov mus rau forgings. Lub sijhawm ntawd, tsis muaj lub tshuab drilling rau qhov ua tiav ntawm lub cev lub cev valve, yog li nws tsuas yog tuaj yeem drilled los ntawm tes, thiab tom qab ntawd kho los ntawm tus kws kho. Tom qab kov yeej ntau yam teeb meem, peb thaum kawg ua tiav hauv kev sim tsim NPS3 / 8 ~ NPS2 nruab nrab-siab steel rooj vag li qub thiab lub ntiaj teb li qub, uas tau txais tos zoo los ntawm cov neeg siv. Nyob rau hauv ib nrab xyoo 1952, Shanghai Yuanta, Zhongxin, Weiye, Lianggong thiab lwm lub Hoobkas tau ua haujlwm ntawm kev sim tsim thiab kev tsim khoom loj ntawm cov hlau cam khwb cia rau roj av. Lub sijhawm ntawd, cov qauv tsim thiab cov qauv Soviet tau siv, thiab cov kws tshaj lij tau kawm los ntawm kev ua, thiab kov yeej ntau yam teeb meem hauv kev tsim khoom. Kev sim tsim khoom ntawm Shanghai cam khwb cia hlau li qub tau teeb tsa los ntawm Ministry of Petroleum, thiab kuj tau txais kev koom tes ntawm ntau lub Hoobkas hauv Shanghai. Asia Factory (tam sim no Shanghai Tshuab Kho Hoobkas) tau muab cov hlau castings uas ua tau raws li qhov yuav tsum tau ua, thiab Sifang Boiler Factory tau pab hauv kev tua hluav taws. Qhov kev sim thaum kawg ua tiav hauv kev sim tsim khoom ntawm cov hlau cam khwb cia valve prototype, thiab tam sim ntawd teeb tsa kev tsim khoom loj thiab xa mus rau Yumen Oilfield rau kev siv raws sijhawm. Tib lub sijhawm, Shenyang Chengfa Iron Works thiab Shanghai Daxin Iron Works kuj tau muabcov qhov dej siab qisnrog rau qhov loj me me rau cov chaw tsim hluav taws xob, Anshan Iron thiab Steel Company yuav rov pib tsim khoom thiab kev tsim kho hauv nroog.

Thaum lub sijhawm rov zoo ntawm lub tebchaws kev lag luam, kuv lub tebchaws txoj kev lag luam valve tau tsim kho sai. Xyoo 1949, cov zis valve tsuas yog 387t, uas tau nce mus txog 1015t hauv xyoo 1952. Technically, nws tau tsim cov hlau cam khwb cia valves thiab cov valves loj uas tsis tshua muaj siab, uas tsis yog tsuas yog muab cov valves sib phim rau kev rov zoo ntawm lub tebchaws kev lag luam, tab sis kuj tsim lub hauv paus zoo rau kev txhim kho yav tom ntej ntawm Tuam Tshoj txoj kev lag luam valve.

02Kev lag luam valve pib

Xyoo 1953, kuv lub teb chaws tau pib nws txoj kev npaj tsib xyoos thawj zaug, thiab cov lag luam kev lag luam xws li roj av, kev lag luam tshuaj lom neeg, metallurgy, hluav taws xob thiab thee txhua yam tau ua kom nrawm dua ntawm kev txhim kho. Lub sijhawm no, qhov xav tau rau cov li qub tau nce ntxiv. Lub sijhawm ntawd, txawm hais tias muaj ntau lub Hoobkas me me ntiag tug tsim cov li qub, lawv lub zog tsis muaj zog, lawv cov khoom siv qub dhau lawm, lawv cov Hoobkas yooj yim, lawv cov nplai me dhau, thiab lawv tawg ua ntau dhau. Txhawm rau kom ua tau raws li qhov xav tau ntawm kev txhim kho sai ntawm lub teb chaws kev lag luam, Thawj Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam Machinery (hu ua Thawj Lub Tsev Haujlwm Saib Xyuas Machinery) txuas ntxiv rov tsim dua thiab hloov pauv cov lag luam ntiag tug qub thiab nthuav dav cov khoom siv li qub. Tib lub sijhawm, muaj cov phiaj xwm thiab cov kauj ruam los tsim cov pob txha caj qaum thiab cov li qub tseem ceeb. Kev lag luam, kuv lub teb chaws txoj kev lag luam li qub tau pib.

1. Kev hloov kho dua tshiab ntawm kev lag luam valve theem ob hauv Shanghai

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

Nws tau muab tawm tias muaj 60 lossis 70 lub Hoobkas me me valve hauv Shanghai. Cov Hoobkas loj tshaj plaws no tsuas muaj 20 txog 30 tus neeg xwb, thiab cov Hoobkas me tshaj plaws tsuas muaj ob peb tus neeg xwb. Txawm hais tias cov Hoobkas valve no tsim cov valve, lawv cov thev naus laus zis thiab kev tswj hwm yog qhov qub heev, cov khoom siv thiab cov tsev Hoobkas yooj yim, thiab cov txheej txheem tsim khoom yooj yim. Qee qhov tsuas muaj ib lossis ob lub tshuab lathes yooj yim lossis cov cuab yeej siv tshuab siv, thiab tsuas muaj qee lub cub tawg crucible rau casting, feem ntau ntawm cov uas ua haujlwm tes. , tsis muaj peev xwm tsim qauv thiab cov khoom siv kuaj. Qhov xwm txheej no tsis haum rau kev tsim khoom niaj hnub, thiab nws tsis tuaj yeem ua tau raws li cov kev xav tau tsim khoom ntawm lub xeev, thiab nws tsis yooj yim sua kom tswj tau qhov zoo ntawm cov khoom valve. Txog qhov kawg no, Tsoomfwv Shanghai Municipal People's tau tsim kev koom tes nrog cov chaw tsim khoom valve hauv Shanghai, thiab tsim Shanghai Pipeline Switches No. 1, No. 2, No. 3, No. 4, No. 5, No. 6 thiab lwm lub tuam txhab hauv nruab nrab. Ua ke cov saum toj no, kev tswj hwm hauv nruab nrab ntawm kev siv tshuab thiab zoo, uas ua rau muaj kev tswj hwm tawg thiab tsis sib haum xeeb, yog li ua rau feem ntau ntawm cov neeg ua haujlwm txaus siab los tsim kev sib raug zoo, qhov no yog thawj qhov kev hloov pauv loj ntawm kev lag luam valve.

Tom qab kev koom tes ntawm pej xeem thiab ntiag tug hauv xyoo 1956, kev lag luam valve hauv Shanghai tau dhau los ua qhov kev hloov kho thib ob thiab kev hloov kho dua tshiab ntawm kev lag luam loj, thiab cov tuam txhab tshaj lij xws li Shanghai Construction Hardware Company, Petroleum Machinery Parts Manufacturing Company thiab General Machinery Company tau tsim. Lub tuam txhab valve uas koom nrog kev lag luam kho vajtse tau tsim Yuanda, Rongfa, Zhongxin, Weiye, Jinlong, Zhao Yongda, Tongxin, Fuchang, Wang Yingqi, Yunchang, Dehe, Jinfa, thiab Xie los ntawm thaj av.

Ib ceg tog thiab ib lub koom haum ua haujlwm sib koom ua ke tau tsim nyob rau hauv lub Hoobkas hauv nruab nrab. Tsoomfwv tau muab cov neeg sawv cev rau pej xeem los ua tus thawj coj saib xyuas kev ua haujlwm, thiab tau tsim cov koom haum tsim khoom, kev muab khoom, thiab kev lag luam nyiaj txiag, thiab maj mam siv cov txheej txheem tswj hwm zoo ib yam li cov tuam txhab lag luam hauv xeev. Tib lub sijhawm, thaj chaw Shenyang kuj tau koom ua ke 21 lub Hoobkas me me rau hauv Chengfa.Rooj vag ValveHoobkas. Txij thaum ntawd los, lub xeev tau coj cov lag luam me thiab nruab nrab mus rau hauv txoj kev npaj hauv tebchaws los ntawm cov koom haum tswj hwm ntawm txhua qib, thiab tau npaj thiab teeb tsa cov khoom siv valve. Qhov no yog kev hloov pauv hauv kev tswj hwm kev tsim khoom ntawm cov lag luam valve txij li thaum tsim lub Tuam Tshoj Tshiab.

2. Shenyang General Machinery Factory tau hloov mus rau kev tsim khoom siv valve

Tib lub sijhawm uas tau hloov kho dua tshiab ntawm cov chaw tsim khoom siv valve hauv Shanghai, Chav Haujlwm Tshuab Thawj Zaug tau faib cov khoom tsim tawm ntawm txhua lub Hoobkas ncaj qha, thiab qhia meej txog kev coj ua haujlwm ntawm cov chaw tsim khoom ncaj qha thiab cov chaw tsim khoom hauv xeev loj dua. Shenyang General Machinery Factory tau hloov mus ua lub chaw tsim khoom siv valve. Lub tuam txhab ua ntej ntawm lub Hoobkas yog lub chaw ua haujlwm hauv tebchaws thiab lub Hoobkas Japanese pseudo-industry Dechang. Tom qab tsim New China, lub Hoobkas feem ntau tsim ntau yam cuab yeej tshuab thiab cov yeeb nkab sib txuas. Xyoo 1953, nws tau pib tsim cov tshuab ua haujlwm ntoo. Xyoo 1954, thaum nws nyob hauv qab kev tswj hwm ntawm Chav Haujlwm Thawj Zaug ntawm Lub Tsev Haujlwm Tshuab, nws muaj 1,585 tus neeg ua haujlwm thiab 147 pawg ntawm ntau yam tshuab thiab khoom siv. Thiab nws muaj peev xwm tsim cov hlau cam khwb cia, thiab lub zog kev txawj ntse muaj zog heev. Txij li xyoo 1955, txhawm rau hloov kho rau kev tsim kho ntawm lub teb chaws txoj kev npaj, nws tau hloov mus rau kev tsim khoom valve, rov tsim kho cov hlau qub, sib dhos, cuab yeej, kho tshuab thiab cov chaw ua haujlwm casting hlau, tsim lub chaw ua haujlwm riveting thiab vuam tshiab, thiab tsim kom muaj chaw kuaj mob hauv nruab nrab thiab chaw kuaj xyuas metrological.

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 sim tsim ultra-high pressure valves nrog qhov loj me ntawm DN3 ~ DN10 thiab nominal siab ntawm PN1500 ~ PN2000 rau lub cuab yeej kuaj polyethylene siab; Shanghai Daxin Iron Factory tsim rau kev lag luam metallurgical Lub high-temperature kub cua valve nrog qhov loj me ntawm DN600 thiab lub flue valve ntawm DN900; Lub Hoobkas Dalian Valve, Lub Hoobkas Wafangdian Valve, thiab lwm yam kuj tau ua tiav kev loj hlob sai. Kev nce ntxiv ntawm ntau yam thiab ntau npaum li cas ntawm cov li qub tau txhawb nqa kev loj hlob ntawm kev lag luam valve. Tshwj xeeb tshaj yog nrog rau kev xav tau kev tsim kho ntawm "Great Leap Forward" kev lag luam, cov chaw tsim khoom me me thiab nruab nrab tau tshwm sim thoob plaws lub tebchaws. Los ntawm xyoo 1958, cov tuam txhab tsim khoom valve hauv tebchaws muaj ze li ntawm ib puas, tsim ib pab pawg tsim khoom valve loj heev. Xyoo 1958, tag nrho cov zis ntawm cov li qub tau nce mus txog 24,163t, nce 80% piv rau xyoo 1957; Thaum lub sijhawm no, kuv lub tebchaws cov khoom tsim khoom valve tau muaj nws thawj qhov siab tshaj plaws. Txawm li cas los xij, vim yog kev tshaj tawm ntawm cov chaw tsim khoom valve, nws kuj tau coj ntau yam teeb meem. Piv txwv li: tsuas yog nrhiav kom muaj nuj nqis, tsis zoo; "ua me me thiab ua loj, cov txheej txheem hauv zos", tsis muaj cov xwm txheej thev naus laus zis; tsim thaum ua, tsis muaj cov tswv yim txheem; theej thiab theej, ua rau muaj kev tsis meej pem txog kev siv tshuab. Vim yog lawv cov cai sib cais, txhua tus muaj ib pawg ntawm cov qauv sib txawv. Cov lus siv ntawm cov li qub tsis sib xws nyob rau ntau qhov chaw sib txawv, thiab lub zog nominal thiab cov koob loj tsis sib xws. Qee lub Hoobkas xa mus rau cov qauv Soviet, qee qhov xa mus rau cov qauv Nyiv, thiab qee qhov xa mus rau Asmeskas thiab Askiv cov qauv. Tsis meej pem heev. Hais txog ntau yam, cov lus qhia tshwj xeeb, qhov ntev ntawm kev sib txuas, qhov ntev ntawm cov qauv, cov xwm txheej xeem, cov qauv xeem, cov cim xim, lub cev thiab tshuaj lom neeg, thiab kev ntsuas, thiab lwm yam. Ntau lub tuam txhab siv txoj kev sib phim ib zaug ntawm "sib phim tus lej ntawm lub rooj zaum", qhov zoo tsis tau lees paub, cov zis tsis nce, thiab cov txiaj ntsig kev lag luam tsis zoo dua. Qhov xwm txheej ntawm lub sijhawm ntawd yog "tawg, tsis sib haum xeeb, ob peb, thiab qis", uas yog, cov chaw tsim khoom li qub tawg txhua qhov chaw, kev tswj hwm tsis sib haum xeeb, tsis muaj cov qauv kev sib koom ua ke thiab cov lus qhia, thiab cov khoom tsis zoo.
