Txheej txheem cej luam
Valveyog ib yam khoom tseem ceeb hauv cov tshuab dav dav.Nws yog ntsia rau ntawm ntau cov kav dej lossis cov khoom siv los tswj cov dej ntws ntawm qhov nruab nrab los ntawm kev hloov cov channel hauv lub valve.Nws cov haujlwm yog: txuas lossis txiav tawm qhov nruab nrab, tiv thaiv qhov nruab nrab los ntawm ntws rov qab, kho qhov tsis xws li qhov nruab nrab siab thiab ntws, hloov cov kev taw qhia ntws ntawm qhov nruab nrab, faib qhov nruab nrab lossis tiv thaiv cov kav dej thiab cov khoom siv los ntawm kev kub siab, thiab lwm yam.
Muaj ntau ntau yam khoom siv valve, uas tau muab faib uarooj vag valve, ntiaj teb valve,kos valve, pob valve,npauj npaim valve, ntsaws valve, diaphragm valve, kev nyab xeeb valve, regulating valve (tswj valve), throttle valve, siab txo valve thiab Traps, thiab lwm yam .;Raws li cov khoom siv, nws tau muab faib ua tooj liab alloy, cam khwb cia hlau, carbon steel, alloy steel, austenitic steel, ferritic-austenitic dual-theem steel, nickel-based alloy, titanium alloy, engineering plastics thiab ceramic li qub, thiab lwm yam. , muaj cov valve tshwj xeeb xws li ultra-siab siab li qub, lub tshuab nqus tsev vacuum, lub hwj chim chaw nres tsheb li qub, li qub rau cov kav dej thiab cov kav dej, cov li qub rau kev lag luam nuclear, li qub rau nkoj thiab cryogenic li qub.Ntau yam ntawm valve tsis, nominal loj los ntawm DN1 (unit in mm) rau DN9750;nominal siab los ntawm ultra-nqus ntawm 1× 10-10 mmHg (1mmHg = 133.322Pa) rau ultra-siab siab ntawm PN14600 (unit ntawm 105 Pa);Kev ua haujlwm kub yog los ntawm ultra-tsawg kub ntawm -269℃mus rau lub ultra-siab kub ntawm 1200℃.
Valve cov khoom yog dav siv nyob rau hauv ntau yam sectors ntawm lub teb chaws kev khwv nyiaj txiag, xws li roj, natural gas, roj thiab roj refining thiab ua thiab pipeline tsheb thauj mus los systems, tshuaj cov khoom, tshuaj thiab zaub mov tsim systems, hydropower, thermal zog thiab nuclear fais fab nroj tsuag;Ntau hom li qub tau siv dav hauv cov cua sov thiab lub zog siv hluav taws xob, cov tshuab tsim hluav taws xob metallurgical, lub tshuab ua kua dej rau cov nkoj, tsheb, dav hlau thiab ntau yam kev ua kis las, thiab kev siv dej thiab cov kav dej rau kev ua liaj ua teb.Tsis tas li ntawd, hauv thaj chaw 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 lag luam suav rau feem ntau ntawm cov khoom siv tshuab.Raws li kev txheeb cais ntawm cov teb chaws muaj kev lag luam txawv teb chaws, cov txiaj ntsig ntawm cov khoom siv li qub yog kwv yees li 5% ntawm cov nqi tsim tawm ntawm tag nrho cov tshuab kev lag luam.Raws li kev txheeb cais, ib txwm muaj nuclear fais fab nroj tsuag muaj li ntawm ob lab kilowatt units muaj txog 28,000 sib koom li qub, ntawm 12,000 yog nuclear kob li qub.Niaj hnub nimno loj-scale petrochemical complex yuav tsum tau ntau pua txhiab ntawm ntau yam li qub, thiab kev nqis peev hauv li qub feem ntau suav txog 8% txog 10% ntawm tag nrho cov peev txheej hauv cov khoom siv.
Cov xwm txheej dav dav ntawm kev lag luam valve hauv Suav teb qub
01 Qhov chaw yug ntawm Tuam Tshoj txoj kev lag luam valve: Shanghai
Hauv Suav teb qub, Shanghai yog thawj qhov chaw tsim khoom li qub hauv Suav teb.Xyoo 1902, Pan Shunji Copper Rhiav, nyob ntawm Wuchang Road, Hongkou District, Shanghai, pib tsim cov khoom me me ntawm cov tshuaj yej faucets los ntawm tes.Lub teapot faucet yog ib hom cam khwb cia tooj liab.Nws yog thawj qhov chaw tsim khoom valve hauv Suav teb paub txog tam sim no.Xyoo 1919, Deda (Shengji) Hardware Factory (tus thawj coj ntawm Shanghai Transmission Machinery Factory) tau pib los ntawm lub tsheb kauj vab me me thiab pib tsim me me-inch tooj liab cocks, ntiaj teb li qub, rooj vag li qub thiab hluav taws kub hydrants.Kev tsim cov cam khwb cia hlau li qub tau pib hauv xyoo 1926, nrog qhov siab tshaj plaws nominal loj ntawm NPS6 (hauv ntiv tes, NPS1 = DN25.4).Lub sijhawm no, cov chaw tsim khoom kho vajtse xws li Wang Yingqiang, Dahua, Lao Demao thiab Maoxu kuj tau qhib los tsim cov li qub.Tom qab ntawd, vim qhov kev xav tau ntawm cov kav dej hauv kev ua lag luam tau nce ntxiv, lwm cov khoom lag luam kho vajtse, cov chaw tsim khoom hlau, cov xuab zeb foundry (casting) factories thiab tshuab factories tau qhib los tsim cov li qub.
Lub valve tsim pab pawg yog tsim nyob rau hauv cov cheeb tsam ntawm Zhonghongqiao, Waihongqiao, Daming Road thiab Changzhi Road nyob rau hauv Hongkou District, Shanghai.Lub sijhawm ntawd, cov khoom lag luam muag zoo tshaj plaws hauv kev lag luam hauv tsev yog "Nes Head", "Peb 8", "Peb 9", "Ob Npib", "Iron Anchor", "Chicken Ball" thiab "Eagle Ball".Tsawg-siab cam khwb cia tooj liab thiab cam khwb cia hlau valve cov khoom yog tsuas yog siv rau cov kav dej li qub nyob rau hauv lub tsev thiab huv chaw, thiab ib tug me me ntawm cam khwb cia hlau li qub kuj siv nyob rau hauv lub teeb textile kev lag luam sector.Cov chaw tsim khoom no me me heev, nrog cov cuab yeej rov qab, cov cuab yeej cog yooj yim thiab cov zis tawm qis, tab sis lawv yog qhov chaw yug ntxov tshaj plaws ntawm Tuam Tshoj txoj kev lag luam valve.Tom qab ntawd, tom qab tsim los ntawm Shanghai Construction Hardware Association, cov tuam txhab valve tau koom nrog lub koom haum ib zaug thiab dhau los ua pawg dej.tus tswv cuab.
02Ob lub chaw tsim khoom lag luam loj
Thaum pib ntawm xyoo 1930, Shanghai Shenhe Machinery Factory tau tsim cov hlau cam khwb cia qis qis hauv qab NPS12 rau dej ua haujlwm.Xyoo 1935, lub Hoobkas tau tsim kev koom tes nrog Xiangfeng Iron Pipe Factory thiab Xiangtai Iron Co., Ltd. cov tswv cuab los tsim Daxin Hlau Hoobkas (tus thawj coj ntawm Shanghai Tsheb kauj vab Factory), xyoo 1936 Ua tiav thiab muab tso rau hauv ntau lawm, muaj ze li ntawm 100 tus neeg ua haujlwm. , nrog imported 2.6 zhang (1 zhang≈3.33m) tshuab dhos thiab nqa cov cuab yeej, feem ntau tsim cov khoom lag luam thiab cov khoom siv mining, cov kav dej cam khwb cia hlau thiab cov cam khwb cia hlau li qub, qhov nominal loj ntawm lub valve yog NPS6 ~ NPS18, thiab Nws tuaj yeem tsim thiab muab cov khoom tiav ntawm cov dej rau cov nroj tsuag dej, thiab cov khoom raug xa tawm mus rau Nanjing, Hangzhou thiab Beijing.Tom qab "Lub Yim Hli 13" Japanese invaders nyob Shanghai hauv xyoo 1937, feem ntau ntawm cov nroj tsuag thiab cov khoom siv hauv lub Hoobkas raug rhuav tshem los ntawm Japanese phom tua hluav taws.Xyoo tom ntej no tau nce peev thiab rov ua haujlwm dua.NPS14 ~ NPS36 cam khwb cia hlau rooj vag li qub, tab sis vim muaj kev lag luam kev nyuaj siab, kev lag luam qeeb, thiab kev ua haujlwm tsis zoo, lawv tsis tuaj yeem rov qab mus txog thaum ua ntej ntawm kev tsim ntawm Tuam Tshoj Tshiab.
Xyoo 1935, tsib tus tswv lag luam suav nrog Li Chenghai, ib tus neeg ua lag luam hauv tebchaws, koom ua ke tsim Shenyang Chengfa Iron Factory (tus thawj coj ntawm Tieling Valve Factory) ntawm Shishiwei Road, Nancheng District, Shenyang City.Kho thiab tsim cov li qub.Xyoo 1939, lub Hoobkas tau tsiv mus rau Beierma Road, Tiexi District rau kev nthuav dav, thiab ob lub rooj cob qhia loj rau casting thiab machining tau tsim.Los ntawm 1945, nws tau loj hlob mus rau 400 tus neeg ua haujlwm, thiab nws cov khoom tseem ceeb yog: cov boilers loj, cam khwb cia tooj liab li qub, thiab underground cam khwb cia hlau rooj vag li qub nrog lub npe loj hauv qab DN800.Shenyang Chengfa Hlau Hoobkas yog lub chaw tsim khoom valve tawm tsam kom muaj sia nyob hauv Suav teb qub.
03 Kev lag luam valve hauv qab
Thaum lub sij hawm Anti-Japanese Tsov rog, ntau lub lag luam hauv Shanghai thiab lwm qhov chaw tau tsiv mus rau sab qab teb sab hnub poob, yog li tus naj npawb ntawm cov lag luam hauv Chongqing thiab lwm qhov chaw hauv cheeb tsam tom qab tau nce siab, thiab kev lag luam pib tsim.Xyoo 1943, Chongqing Hongtai Machinery Factory thiab Huachang Machinery Factory (ob lub tsev lag luam yog cov thawj coj ntawm Chongqing Valve Factory) pib kho thiab tsim cov kav dej thiab cov valve uas tsis tshua muaj siab, uas ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom ua tsov rog nyob rau tom qab thiab daws cov neeg pej xeem. li qub.Tom qab yeej ntawm Anti-Japanese Tsov Rog, Lisheng Hardware Factory, Zhenxing Industrial Society, Jinshunhe Hardware Factory thiab Qiyi Hardware Factory tau ua tiav qhib los tsim cov khoom me me.Tom qab kev tsim ntawm Tuam Tshoj Tshiab, cov chaw tsim khoom no tau koom ua ke rau hauv Chongqing Valve Factory.
Thaum ntawd, ib txhiavalve manufacturershauv Shanghai kuj tau mus rau Tianjin, Nanjing thiab Wuxi los tsim cov chaw tsim khoom los kho thiab tsim cov li qub.Qee lub tuam txhab kho vajtse, hlau yeeb nkab factories, machinery factories los yog shipyards nyob rau hauv Beijing, Dalian, Changchun, Harbin, Anshan, Qingdao, Wuhan, Fuzhou thiab Guangzhou kuj tau koom nrog kho thiab tsim ib co kav dej li qub.
