Lub ntsiab
Ib lub dab tsi uas qhib thiab kawyog ib qho khoom tseem ceeb hauv kev siv tshuab. Nws raug ntsia rau ntau cov kav dej lossis cov khoom siv los tswj cov ntws ntawm nruab nrab los ntawm kev hloov cov chaw channel hauv lub valve. Nws cov haujlwm yog: Txuas lossis txiav tawm ntawm nruab nrab, tiv thaiv kom zoo dua li ntawm nruab nrab lossis tiv thaiv cov raj hluav taws xob lossis cov khoom siv los ntawm kev cuam tshuam, thiab lwm yam.
Muaj ntau ntau yam ntawm cov khoom lag luam valve, uas tau muab faib uarooj vag valve, lub ntiaj teb valve,Kos Valve, pob valve,Npauj Npaim Valve, ntsaws valve, diaphragm valve, valve valve, tswj valve, tswj valve (tswj valve (tswj valve (tswj valve (tswj valve, siab txo lub valve thiab ntxiab, thiab lwm yam .; Raws li cov ntaub ntawv, nws tau muab faib ua tooj liab, cov hlau ua kom zoo nkauj, cov tshuab hluav taws xob, cov khoom siv hluav taws xob zoo nkauj, thiab cov roj ceran Li qub rau kev lag luam nuclear, li qub rau cov nkoj thiab cryogenic li qub. Ntau yam ntawm cov khoom seem valve, nominal loj los ntawm DN1 (chav tsev nyob rau hauv hli) rau DN9750; nominal siab los ntawm ultra-nqus ntawm 1× 10-10 mmhg (1mmHG = 133.32PA) rau ultra-kev kub siab ntawm PN1400 (chav ntawm 105 teev); Kev ua hauj lwm sov ranges los ntawm ultra-tsawg kub ntawm -269℃rau ultra-siab kub ntawm 1200℃.
Phab loj khoom tau siv dav hauv ntau cov haujlwm ntawm kev lag luam hauv tebchaws, xws li roj, roj thiab siv tshuaj lom neeg thiab cov khoom siv hluav taws xob ntau lawm thiab cov hluav taws xob nuclear; Ntau hom ntawm li qub yog siv nyob rau hauv cov cua sov thiab fais fab siv tshuab, tsheb tshuab, thiab cov pa roj hmab thiab cov dej ua kom tsis haum. Ib qho ntxiv, hauv cov teb ntawm cov thev naus laus zis tshiab xws li kev tiv thaiv thiab aerospace, ntau yam li qub nrog cov khoom tshwj xeeb kuj tau siv.
Valve Cov Khoom Siv rau ib feem ntawm cov khoom lag luam kho tshuab. Raws li cov txheeb cais ntawm cov teb chaws txawv teb chaws, cov zis ntawm cov nyiaj muaj txiaj ntsig rau kwv yees li 5% ntawm cov zis cov txiaj ntsig ntawm kev lag luam machiner tag nrho. Raws li kev txheeb cais, cov tsoos nuclear fais fab cog tau muaj ntawm ob lab pawg muaj kwv yees li 28,000 qhov uas muaj txog 12,000 leej ntawm 12,000 leej nuclear Islam li qub. Ib qho niaj hnub loj-teev petrochemical complex yuav tsum muaj ntau pua txhiab tus li qub, thiab kev nqis peev ntau yam nyiaj rau 8% rau 10% ntawm tag nrho cov peev txheej hauv cov cuab yeej.
Qhov xwm txheej dav dav ntawm Valve Kev Lag Luam Hauv Suav Tebchaws Suav
01 Lub Chaw Yug Ntawm Tuam Tshoj Qhov Chaw Lag Luam Valve: Shanghai
Nyob rau hauv Suav teb qub, Shanghai yog thawj qhov chaw los tsim cov khoom siv nyob hauv Suav teb. Xyoo 1902, Yias Shunji Tooj Liab Rhiav, nyob ntawm Wuchang Road, Hongkou koog tsev kawm ntawv, Shanghai, pib ua khoom me me ntawm Teapot kais dej los ntawm txhais tes. Lub teapot kais dej yog ib hom ntawm nrum qaib dib. Nws yog qhov chaw tsim khoom tshiab tshaj plaws hauv Suav teb paub kom deb li deb. Xyoo 1919, Deda (Shengji) lub Hoobkas kho vajtse ntawm Shanghai lub tsheb kauj vab copery, pib los ua cov tsheb me me, lub ntiaj teb li qub thiab hluav taws kub. Kev tsim cov khoom cam duab ua haujlwm tau pib pib thaum xyoo 1926, muaj qhov siab tshaj plaws nominal loj ntawm NSS6 (hauv nti (hauv nti, NPS1 = DN25.4. Nyob rau lub sijhawm no, cov khoom siv kho vajtse xws li Wang Yingqiang, Dahua, Nplog Demao thiab Maoxu tseem qhib rau cov khoom siv. Tom qab, vim tias qhov nce hauv kev thov rau cov kav dej tsis zoo hauv kev ua lag luam, lwm cov khoom siv kho vajtse, Casting) chaw ua haujlwm tau qhib rau kev tsim cov khoom li qub ib.
Ib pawg valve yog tsim nyob rau hauv thaj chaw ntawm zhonghongqiao, Waihongqiao, txoj kev khiav thiab Changzhi Road thiab Changkou koog tsev kawm ntawv, Shanghai. Lub sijhawm ntawd, cov khoom muag zoo tshaj plaws hauv kev ua lag luam hauv tsev yog "lub taub hau", "ob lub npib pob" thiab "dav dawb hau". Tsawg-siab nrum tooj liab thiab cov khoom siv hlau cam khwb cia yog siv rau cov kav dej khov kho hauv tsev Cov chaw tsim khoom no tsawg heev hauv cov nplai, nrog cov khoom siv rov qab, cov khoom siv cog qoob loo yooj yim thiab cov khoom tawm hauv lub valve, tab sis lawv yog qhov chaw yug me nyuam ua ntej ntawm Tuam Tshoj txoj kev lag luam valve. Tom qab, tom qab tsim ntawm Shangai Siv Khoom Siv Kho Vaj Tse, cov chaw tsim hluav taws xob no tau koom nrog ib qho ntxiv thiab los ua cov pab pawg waterway. Tswvcuab.
02TWO LOJ-NPLAI VALVE RAUG TSOB NROJ
Thaum pib ntawm 1930, Shanghai Shenhe machinery lub Hoobkas tsim kom muaj cov rooj vag hlau rooj vag li qub hauv qab ntawm Nps12 rau dej ua haujlwm. Xyoo 1935, lub tuam txhab tsim kev sib koom ua ke nrog Xiangfeng Hlau Yeeb Nkab Hoobkas (nyob rau hauv 1936 ua tiav thiab muab tso rau ntau dua 100 tus neeg ua haujlwm, nrog imported 2.6 zhang (1 zhang≈3.33m) Lathes thiab nqa cov khoom siv, feem ntau yog tsim khoom siv thiab muab cov khoom siv hlau ua tiav, thiab cov khoom lag luam luam tawm rau cov khoom siv dej Nanjing, Hangzhou thiab Beijing. Tom qab "Lub Yim Hli 13" Japanese Invaders nyob Shanghai hauv xyoo 1937, feem ntau, cov khoom siv hauv lub Hoobkas tau raug rhuav tshem los ntawm Japanese Artily Hluav Taws. Cov xyoo tom qab nce peev thiab rov ua haujlwm. NPS14 ~ NPS36 cam khwb cia hlau rooj vag kev nyuaj siab, tab sis kev ua lag luam qeeb, lawv tsis tau rov qab rau thaum Eve ntawm lub nrhiav ntawm Suav teb tshiab.
Xyoo 1935, tsib tus tswv cuab suav nrog Li Chenghang, tus neeg ua haujlwm hauv tebchaws Shenyang (Testional) Kho thiab chaw tsim khoom. Xyoo 1939, lub Hoobkas tau hloov mus rau Besierman txoj kev, tieki koog tsev kawm ntawv rau kev nthuav dav, thiab muab ob lub rooj cob qhia loj rau Casting thiab Machining tau ua. Los ntawm 1945, nws tau loj hlob mus rau 400 tus neeg ua haujlwm tau, thiab nws cov khoom lag luam loj, thiab pob zeb khov kho cov hlau rooj vag yog ib qho loj me me hauv qab dn800. Shenyang Chengfa Hlau Hoobkas yog lub chaw tsim tshuaj paus valve nyuaj kom muaj sia nyob hauv Suav teb qub.
03Qhov valve kev lag luam hauv lub nraub qaum
Thaum lub sij hawm los tiv thaiv kev ua tsov ua rog, ntau yam kev lag luam hauv Shanghai thiab lwm qhov chaw ua haujlwm tau tsiv mus rau sab qab teb thiab lwm qhov chaw nyob rau tom qab thaj chaw sounded, thiab kev lag luam pib tsim. Xyoo 1943, chongqing hongtai machinery Hoobkas thiab huchang tshuab (ob lub chaw tsim khoom siv Tom qab yeej ntawm kev tiv thaiv kev ua tsov rog, Lisheng kho vajtse Hoobkas thiab QIshun Hardware Hoobkas thiab QIYI Hardware Hoobkas tau qhib me me. Tom qab lub tsom iav tshiab, cov chaw tsim khoom no tau sib xyaw ua ke rau hauv CHongqing Valve Hoobkas.
Lub sijhawm ntawd, qee leejTxoj Valve Cov Chaw Tsim TshuajHauv Shanghai tseem tau mus rau Tianjin, Nanjing thiab Wuxi los tsim cov chaw ua haujlwm los kho thiab tsim cov khoom li cas. Qee cov khoom siv kho vajtse, cov yeeb nkab cov khoom siv hlau, cov khoom siv hluav taws xob lossis cov khoom siv tsis zoo, elsan, Fuzhou kuj tau koom nrog kev kho thiab tsim qee cov kav dej khib nyiab.
