Thawj theem ntawm lub valve kev lag luam (1949-1959)
01organize kom pab ua haujlwm rov qab los ntawm kev lag luam hauv tebchaws
Lub sijhawm los ntawm 1949 txog 1952 yog lub sijhawm ntawm kuv lub tebchaws ua lag luam rov qab. Vim tias cov kev xav tau ntawm kev tsim kho nyiaj txiag, lub teb chaws ceev yuav tsum muaj ntau ntawmli qub, tsis yogTsawg Lub Siab Li Qub, tab sis kuj yog ib lub pob ntawm cov siab thiab nruab nrab siab li qub uas tsis tsim lub sijhawm ntawd. Yuav ua li cas npaj valve ntau lawm kom tau raws li qhov kev xav tau ceev ntawm lub teb chaws yog ib txoj haujlwm hnyav thiab nyuaj.
1. Qhia thiab Txhawb Ntau Lawm Ntau Lawm
Raws li txoj cai ntawm "tsim kev tsim khoom, vam meej kev lag luam, thiab muaj txiaj ntsig zoo rau pej xeem thiab cov lag luam me me kom rov ua haujlwm thiab tsim li qub. Nyob rau Eve ntawm lub nrhiav ntawm cov neeg lub koom pheej ntawm Tuam Tshoj, Shenyang Chengfa Hlau Thaum nws muaj kev ua lag luam tsuas yog 7 tus neeg ua haujlwm tsuas yog 7 cov cuab yeej muag kom muaj nuj nqis. Tom qab lub tswv yim ntawm lub Tuam Tshoj tshiab, nrog kev txhawb nqa ntawm cov neeg tseemfwv, lub Hoobkas pib kev tsim khoom, thiab cov neeg ua haujlwm tau nce los ntawm 7 txog 96 thaum nws tau pib. Tom qab, lub Hoobkas tau txais cov khoom siv los ntawm Shenyang Hardware tuam txhab, thiab cov khoom lag luam coj los saib tshiab. Tus naj npawb ntawm cov neeg ua haujlwm tau nce mus rau 329, nrog ib xyoos cov zis txhua xyoo ntawm 610 teev ntawm ntau yam li qub, nrog cov zis tawm ntawm 830,000 Yuan. Nyob rau tib lub sijhawm hauv Shanghai, tsis yog cov lag luam ntiag tug uas tau ua rau cov lag luam me me, tab sis nrog kev txhim kho me me, tab sis nrog kev txhim kho cov koom haum ntiag tug
2. Unified Purchase thiab Muag Khoom, Npaj Valve Ntau Lawm
Nrog ntau tus neeg lag luam ntiag tug tig mus rau hauv valve ntau lawm, cov thawj Shanghai Siv Lub Koom Haum Kho Vajtse tau ua tsis tau raws kev txhim kho. Xyoo 1951, Shanghai Valve tsim 6 txoj kev sib koom tes rau kev ua haujlwm ntawm Shanghai kev yuav khoom ntawm Tuam Tshoj Tuam Tshoj Tuam Tshoj, thiab ua kev sib koom tes thiab kev muag khoom. Piv txwv li, daxin hlau ua haujlwm, uas tau ua txoj haujlwm ntawm cov khoom loj uas muaj kev lag luam ntawm cov neeg siv hluav taws xob, Raws li kev taw qhia txog kev tswj hwm roj av ntawm Ministry of Leg kev lag luam, cov xaj xaj ncaj qha, thiab tom qab ntawd tig mus ua cov xaj. Cov neeg lub tseem fwv tau pab cov chaw lag luam ntiag tug uas tau kov yeej cov neeg ua lag luam thiab kev muag khoom thiab cov khoom lag luam ntawm cov khoom siv hluav taws xob, nws tau muab cov khoom siv hluav taws xob ntau yam, nws tau muab cov khoom lag luam loj, nws tau muab cov khoom lag luam loj heev rau cov khoom lag luam ntiag tug
3. Kev tsim kho rau Kev Txum Tim Rov Qab Los Ntawm Kev Pabcuam Kev Siv Kev Siv Hauv Tebchaws
Hauv thawj tsib-xyoo phiaj xwm, lub xeev tau txheeb xyuas 156 tus tseem ceeb tsim kev tsim kho yumen roj thiab steel tuam txhab tsim khoom yog ob txoj haujlwm loj. Txhawm rau rov ua dua cov khoom lag luam hauv yumen upfield sai li sai tau, cov roj av kev lag luam ntawm cov roj av machinery qhov chaw hauv Shanghai. Shanghai Jinlong Hardware Factory and others have undertaken the task of trial-producing a batch of medium-pressure steel valves. Nws yog contrivable rau xav txog qhov nyuaj ntawm kev sim-tsim cov khoom nruab nrab nruab nrab ntawm cov chaw ua haujlwm me me. Qee cov ntau yam yuav raug rho tawm raws li cov qauv muab los ntawm cov neeg siv, thiab cov khoom tiag yog kev tshawb fawb thiab mapped. Txij li qhov zoo ntawm cov hlau castings tsis zoo txaus, thawj thawj cam khwb cia steel valve lub cev tau hloov mus rau kev lom zem. Lub sijhawm ntawd, tsis muaj kev tuag rau lub oblique lub qhov ua ntawm lub ntiaj teb valve lub cev, yog li nws tsuas tuaj yeem txav los ntawm tes, thiab tom qab ntawd kho los ntawm fitter. Tom qab kov yeej ntau yam kev nyuaj, peb thaum kawg ua tiav hauv kev sib hais tau ntau lawm hauv NPS3 / 8 ~ Nps2 Nruab Nrab Hlau Cov Khoom Siv Hlau, uas tau txais zoo tau txais los ntawm cov neeg siv. Nyob rau hauv ob ib nrab ntawm 1952, Shanghai Yuarda, Whongxin, WeIy, weiGong thiab lwm yam kev sib tw ua tiav thiab zaws cov khoom siv hlau li qub rau roj av. Lub sijhawm ntawd, cov qauv qhia txog Soviet thiab cov qauv siv tau siv, thiab cov kws tshaj lij tau kawm los ntawm kev ua, thiab kov yeej ntau yam hauv kev tsim khoom. Qhov kev sib hais ntau lawm ntawm Shanghai nrum cov cuab yeej siv hlau loj tau txhim tsa los ntawm kev ua haujlwm ntawm cov roj av, thiab tseem tau txais kev koom tes ntawm ntau yam hauv Shanghai. Asia Hoobkas (tam sim no Shanghai Tshuab Kho Hoobkas) Muab cov hlau kis uas tau ntsib qhov yuav tsum tau ua, thiab Sifang Boiler Boiler lub Hoobkas tau txais kev thuam. Qhov kev ntsuas thaum kawg tau ua tiav hauv kev sib hais ntawm cov cam khwb cia steel valve qauv thiab xa nws mus rau yumen materfield rau siv raws sijhawm. Nyob rau tib lub sijhawm, Shenyang Chengfa hlau ua haujlwm thiab Shanghai Daxin Hlau Ua Haujlwm Tau muab rauLow-siab li qubNrog rau cov nominal loj dua rau cov nroj tsuag fais fab loj rau cov nroj tsuag fais fab, hom phiaj hlau thiab steel tuam txhab los rov ua dua thiab hauv nroog tsim khoom.
Thaum lub sij hawm rov qab ntawm kev lag luam hauv tebchaws, kuv lub teb chaws lub valve kev lag luam tau tsim sai. Hauv xyoo 1949, lub valve tso zis tau tsuas yog 387t, uas tsis yog muab cov khoom siv hluav taws xob loj, nws tau ua kom muaj kev lag luam zoo rau kev tsim kho yav tom ntej ntawm Tuam Tshoj txoj kev lag luam valve.
02Qhov kev lag luam valve pib
Xyoo 1953, kuv lub tebchaws tau pib nws thawj tsib-xyoo phiaj xwm, thiab kev lag luam xws li roj av, metallurgy, thee tag nrho cov hluav taws xob nrawm ntawm kev txhim kho. Lub sijhawm no, qhov xav tau rau li qub yog khoo. Nyob rau lub sijhawm ntawd, txawm hais tias muaj ntau tus ntawm cov tuam txhab me me ua kom tsis muaj zog, lawv cov khoom siv tau yooj yim, lawv cov nplai me me, lawv tau tawg. Txhawm rau kom tau raws li txoj cai ntawm kev txhim kho ceev ceev ntawm kev lag luam hauv tebchaws, kev ua haujlwm ua ntej ntawm kev lag luam ntiag tug (xa cov khoom lag luam ntiag tug thawj zaug thiab nthuav dav valve. Nyob rau tib lub sijhawm, muaj cov phiaj xwm thiab cov kauj ruam los tsim caj qaum thiab cov khoom tseem ceeb. Kev Lag Luam, Kuv lub teb chaws txoj kev lag luam valve pib.
1. Kev rov kho dua tshiab ntawm kev lag luam theem nrab valve hauv Shanghai
Tom qab pib nrhiav lub Tuam Tshoj tshiab, cov tog uas tau ua raws txoj cai ntawm "kev siv nyiaj, kev txwv thiab kev hloov pauv kev lag luam thiab kev lag luam.
Nws muab tawm tias muaj 60 lossis 70 me me valve tsom kwm nyob rau hauv Shanghai. Qhov loj tshaj plaws ntawm cov khoom lag luam tsuas muaj 20 tus neeg, thiab qhov tsawg tshaj plaws tsuas muaj ob peb tus neeg. Although these valve factories produce valves, their technology and management are very backward, the equipment and factory buildings are simple, and the production methods are simple. Ib txhia tsuas muaj ib lossis ob txoj kev sib tw yooj yim lossis siv cov cuab yeej siv lub cav, thiab tsuas muaj qee qhov cub tawg rau kev ua pov thawj, feem ntau yog kev ua haujlwm ntawm manually. , tsis muaj cov khoom siv muaj peev xwm tsim thiab kuaj. Qhov xwm txheej no tsis haum rau kev tsim khoom tam sim no, tsis tau nws ua tau raws li cov phiaj xwm uas yuav tsum muaj ntawm lub xeev, thiab nws yog tsis yooj yim tswj tau qhov zoo ntawm valve khoom. Txog qhov kawg no, cov neeg sib koom tes nrog cov pej xeem koom tes nrog kev sib koom ua ke nrog lub valve, thiab tsim Shanghai Pipeline Pipelium. Ua ke cov lus saum toj no, tswj hwm hauv phau ntawv ntawm kev siv thev naus laus zis thiab kev tswj hwm zoo li no, yog li kev tswj hwm kev sib raug zoo, yog li kev txhim kho ua ntej loj dua ntawm kev lag luam valve.
Tom qab kev sib koom tes rau pej xeem xyoo 1956, lub tuam txhab kev hloov kho ob zaug ntxiv xws li Shanghai Siv Tuam Txhab thiab General Machinery tuam txhab tau tsim. Lub tuam txhab ntaus pob valve tau tsim kho cov khoom siv kho vajtse tsim tawm tau tsim tsa Yuanfa, Wang Yingqi, Wang Yingqi, Jinfa, Jinfa, thiab XIE los ntawm cheeb tsam. Muaj txog 20 lub chaw ua haujlwm nruab nrab hauv Dalian, Yuchang, Deda, thiab lwm yam. Txhua lub Hoobkas muaj ntau lub suab satisdiction. Ib tog ceg thiab caj taws-cag sib koom ua ke ua hauj lwm pab pawg tau tsim nyob rau hauv cov nroj tsuag central. Tsoomfwv tau muab cov sawv cev rau pej xeem los tswj hwm txoj haujlwm, thiab muab cov koom haum ua haujlwm, thiab maj mam ua kev tswj hwm kev tswj hwm zoo ib yam li lub xeev cov lag luam. Nyob rau tib lub sijhawm, thaj chaw Shenyang kuj sib koom ua ke 21 qhov me me rau hauv ChengfaRooj vag valveHoobkas. Txij thaum ntawd los, lub xeev tau coj kev tsim cov khoom lag luam me thiab nruab nrab hauv lub teb chaws los ntawm cov koomhaum tswj hwm ntawm txhua qib, thiab tau npaj thiab teeb tsa lub chaw tsim khoom. Qhov no yog kev hloov pauv ntawm kev tswj hwm ntau lawm ntawm cov lag luam valve txij li lub tswv yim tshiab ntawm Tuam Tshoj.
2. Shenyang General Machinery Hoobkas hloov mus rau Valve Ntau Lawm
Nyob rau tib lub sijhawm raws li kev txhim khu kev tsim hluav taws xob hauv Shanghai, thiab qhia meej txog cov koom haum ncaj qha ntawm cov chaw ua haujlwm ncaj qha rau lub xeev ncaj qha. Shenyang Genereyang General Machinery Hoobkas tau hloov mus rau hauv ib lub chaw tsim khoom valve. kev lag luam. Lub khw muag khoom ntawm lub Hoobkas yog Bureaucratic peev txheej loj thiab cov neeg Japanese pseudo-kev lag luam lub Hoobkas. Tom qab pib nrhiav tau ntawm lub Tuam Tshoj tshiab, lub Hoobkas feem ntau ua tau ntau yam cuab yeej thiab cov pob zeb ua ke. Xyoo 1953, nws pib tsim cov tshuab ntoo tshuab. Xyoo 1954, thaum nws tau ncaj qha raws li kev tswj hwm ntawm thawj lub chaw haujlwm ntawm cov Machinery Ministry, nws muaj 1,585 teev ntawm ntau yam Machinery thiab cov cuab yeej siv. Thiab nws muaj qhov muaj peev xwm ntau lawm ntawm cam khwb cia steel, thiab kev quab yuam yog qhov muaj zog. Txij li xyoo 1955, nyob rau hauv kom yoog raws li kev txhim kho ntawm lub teb chaws phiaj xwm, ua kom sib dhos, kev kho hluav taws xob tau hloov pauv, thiab tsim kho cov chaw nres tsheb nruab nrab thiab cov chaw nres tsheb metrological. Qee cov kws tshaj lij tau hloov los ntawm Shenyang twj tso twj tso kua mis Hoobkas. Xyoo 1956, 837t ntawmTsawg Lub Siab Li Qubtau tsim tawm, thiab huab hwm coj ntau lawm ntawm cov kev lag luam siab thiab nruab nrab siab tau pib. Xyoo 1959, 4213t ntawm li qub tau tsim tawm, suav nrog 1291t ntawm cov siab thiab nruab nrab siab li qub. Xyoo 1962, nws tau hloov npe nrov nrov High thiab nruab nrab lub siab Valve lub Hoobkas thiab tau dhau los ua ib qho ntawm cov kis las loj tshaj plaws hauv kev lag luam valve.
3. Thawj qhov kawg nkaus ntawm valve ntau lawm
Nyob rau hauv thaum ntxov hnub ntawm lub nrhiav ntawm Suav teb tshiab, kuv lub teb chaws lub valve ntau lawm tau daws los ntawm kev koom tes thiab kev sib ntaus sib tua. Nyob rau hauv "kev ua tiav zoo rau pem hauv ntej" lub sij hawm, kuv lub teb chaws lub valve kev lag luam paub nws thawj cov txheej txheem thawj zaug. Lub Chaw Tso Tawm: 387t xyoo 1949, 8126T 1956, 49746t xyoo 1959, 128.5, thiab 6.1 xyoo ntawm 1956 thaum xyoo 1956 thaum muaj kev sib koom tes pej xeem tau tsim. Kev tsim cov kev lag luam siab thiab nruab nrab lub siab tau pib lig, thiab ntau lawm tau pib thaum xyoo 1956, nrog ib xyoos tawm ntawm 175t. Xyoo 1959, cov zis tau mus txog 1799T, uas yog 10.3 lub sij hawm uas yog xyoo 1956. Kev tsim kho sai ntawm kev tsim kho lub tebchaws tau nce qib ntawm lub valve kev lag luam. Xyoo 1955, Shanghai Lianggong Valve Hoobkas tau kev sim siab ua tiav-tsim lub Christmas ntoo valve rau Yumen Oilfield; Shanghai Yuanda, Zhongxin, WeIye, Wongfa thiab lwm lub tshuab cov hlau sib cav sib ceg thiab cov chiv ua siab muag siab rau cov roj Shenyang Generey General Machinery Hoobkas thiab Suzhou Hlau Hoobkas (tus thawj lub Hoobkas ntawm Suzhou Travely Rau Jilin Tshuaj Muaj Kev Lag Luam Kev Lag Luam Kev Lag Luam Siab; Shenyang Chengfa Hlau Hoobkas Kawm tiav kev sim siab ua kom zoo-tsim hluav taws xob rooj vag valve nrog lub npe loj ntawm DN3000. Nws yog qhov loj tshaj plaws thiab hnyav tshaj plaws hauv Suav teb lub sijhawm ntawd; Shenyang Genereyang General Machinery Hoobkas tau kev sim siab ua ntej tsim kho cov DNTA-kev kub siab ntawm PN3 ~ DNTANY Pressures ntawm PN3500 ~ PN2000 rau qhov kev ntsuas siab Polyethylene ntsuas kev ntsuas qib nrab; Shanghai Daxin Hlau Hoobkas tsim rau kev lag luam metallurgical lub siab-kub huab cua valve nrog ib lub valinal loj ntawm DN900; Dalian valve Hoobkas, Wafangdian Valve Hoobkas, thiab lwm yam.
