Kuv Lub Tebchaws Valve Kev Lag Luam Kev Tshawb Fawb Kev Tshawb Fawb Thiab Kev Pom Zoo

Txij li thaum xyoo 1980, kuv lub teb chaws tau pib npaj cov lag luam tseem ceeb los qhia txog cov thev naus laus zis thiab cov cuab yeej ua haujlwm xws li tsim thiab thev naus laus zis ntawm cov khoom siv txawv teb chaws zoo sib xws, uas tau txhim kho sai sai rau kuv lub teb chaws valve manufacturing technology thiab cov khoom zoo. Tam sim no, cov chaw tsim khoom tseem ceeb hauv tsev tau tsim thiab tsim ntau yam li qub raws li cov qauv thoob ntiaj teb xws li ISO thoob ntiaj teb cov qauv, DIN German cov qauv, AWWA American cov qauv, thiab lwm yam, thiab cov khoom ntawm qee cov tuam txhab tau mus txog thoob ntiaj teb qib siab. qib. Txawm hais tias tag nrho theem ntawm kev lag luam valve tau zoo heev nyob rau hauv ob peb lub xyoos dhau los, qhov zoo tsis ruaj khov txaus, thiab phenomena xws li khiav, popping, dripping, thiab leaking feem ntau tshwm sim nyob rau hauv domestic li qub. Tsis tas li ntawd, tseem muaj qhov sib txawv ntawm kuv lub teb chaws lub valve txhawb kev muaj peev xwm thiab cov teb chaws tsim.

Valve yog cov khoom lag luam uas muaj cov txiaj ntsig qis, thiab kev sib tw ua lag luam yog qhov hnyav heev. Raws li rau kev faib tawm ntawm lub lag luam valve, nws yog tsuas yog raws li kev tsim kho ntawm engineering tej yaam num. Cov neeg siv cov li qub yog kev lag luam petrochemical, hluav taws xob sector, metallurgical sector, tshuaj lom neeg kev lag luam thiab kev tsim kho hauv nroog. Kev lag luam petrochemical feem ntau siv API txheem rooj vag li qub, nres li qub thiab kos li qub; lub zog hluav taws xob feem ntau yog siv lub qhov rooj kub kub siab, nres li qub, kos li qub thiab kev nyab xeeb li qub rau cov chaw nres tsheb fais fab thiab qee qhov qis npauj npaim li qub thiab lub rooj vag li qub rau cov khoom siv dej thiab cov kav dej; kev lag luam tshuaj feem ntau siv Stainless hlau rooj vag li qub, nres li qub, thiab kos li qub; kev lag luam metallurgical feem ntau yog siv lub tshuab hluav taws xob tsawg-ntev npauj npaim li qub, oxygen nres li qub, thiab cov pa oxygen pob li qub; Kev tsim kho hauv nroog feem ntau yog siv cov khoom siv qis qis, xws li cov kav dej hauv nroog feem ntau siv cov qhov rooj loj loj, thiab kev tsim vaj tsev tsev feem ntau siv midline li qub. Npauj npaim li qub, cov cua sov hauv nroog feem ntau yog siv cov hlau nplaum npauj npaim li qub; roj pipelines mas siv lub rooj vag tiaj tus li qub thiab pob li qub; kev lag luam kws tshuaj feem ntau siv stainless hlau pob li qub; kev lag luam khoom noj khoom haus feem ntau yog siv stainless hlau pob li qub, thiab lwm yam li qub tau dav siv hauv kev lag luam kho dej, feem ntau yog cov khoom siv tsis tshua muaj siab, xws li npauj npaim li qub, lub rooj vag li qub, thiab kos li qub. Nws tau nkag siab tias tam sim no muaj ntau dua 2, 000 lub tuam txhab valve ntawm qee qhov ntsuas ntawm lub khw, feem ntau nyob hauv Jiangsu, Zhejiang thiab Central Plains. Txij li cov ntsiab lus technical ntawm cov khoom yog qhov tsawg, kev sib tw yog khaus.

Ntawm ib sab, kuv lub teb chaws cov khoom valve tau ntsib txoj hauv kev loj hlob zoo. Nrog rau kev hloov pauv ntawm kev txhim kho roj mus rau hauv av hauv av thiab thaj chaw roj av, thiab kev txhim kho kev lag luam hluav taws xob los ntawm lub zog hluav taws xob qis dua 300, 000 kilowatts rau thermal zog, hydropower thiab nuclear zog siab dua 300, 000 kilowatts, valve cov khoom yuav tsum tau hloov lawv cov kev ua tau zoo thiab kev ua tau zoo raws li kev hloov hauv cov khoom siv daim ntawv thov teb. parameter. Kev tsim kho hauv nroog feem ntau siv ntau lub tshuab qis qis, thiab tab tom txhim kho rau kev tiv thaiv ib puag ncig thiab txuag hluav taws xob. Ntawd yog, lub rooj vag hlau uas tsis tshua muaj siab siv yav dhau los tau maj mam tig mus rau ib puag ncig tus phooj ywg roj hmab phaj li qub, sib npaug li qub, hlau foob npauj npaim li qub thiab centerline foob npauj npaim li qub. Cov phiaj xwm roj thiab cov roj sib txuas tau tsim nyob rau hauv cov kev taw qhia ntawm cov kav dej, uas yuav tsum muaj ntau lub rooj vag tiaj tus li qub thiab pob li qub. Lwm sab ntawm kev txhim kho lub zog yog kev txuag hluav taws xob. Yog li ntawd, los ntawm qhov kev xav ntawm kev txuag hluav taws xob, cov cuab yeej siv hluav taws xob yuav tsum tau tsim thiab tsim mus rau qhov tsis zoo ntawm subcritical thiab supercritical siab.

Kev tsim kho ntawm cov chaw nres tsheb fais fab yog tsim los ntawm kev loj hlob loj, yog li qhov loj-inch thiab high-pressure kev nyab xeeb li qub thiab siab txo li qub yuav tsum tau, nrog rau ceev qhib thiab kaw li qub. Txhawm rau ua kom tau raws li cov kev xav tau ntawm kev ua tiav ntawm cov haujlwm, cov khoom siv ntawm cov li qub tau tsim los ntawm ib qho ntau yam mus rau ntau yam thiab specifications. Muaj kev nce ntxiv uas txhua qhov xav tau rau qhov project engineering yog muab los ntawm ib lub chaw tsim khoom valve.
