Valve sealing yog ib qho tseem ceeb lav ntawm valve zoo. Valve cov khoom lag luam zoo thiab qib kev muaj feem cuam tshuam rau kev txhim kho ntawm ntau yam xws li roj av, tshuaj lom neeg kev lag luam, hluav taws xob fais fab, kev lag luam nuclear, roj thiab roj xa mus thiab marine engineering. Valve tuam txhab yuav tsum pib los ntawm cov kev xav tau ntawm cov neeg siv downstream, muab qhov tseem ceeb rau kev tshawb fawb thiab kev loj hlob ntawm cov thev naus laus zis tseem ceeb, ntxiv dag zog rau kev tswj hwm, hloov cov xwm txheej tam sim no ntawm kev sib tw qis hauv kev lag luam, thiab txhawb nqa cov khoom valve los txhim kho cov kev taw qhia ntawm kev siv tshuab siab. cov ntsiab lus, siab tsis, muaj zog corrosion kuj thiab lub neej ntev, thiaj li los txhim kho tag nrho cov kev sib tw ntawm kev lag luam.
Cov dej ntws tawm sab hauv ntawm cov dej cua sov li qub ua rau muaj kev hem thawj rau kev ua haujlwm ib txwm ntawm cov cuab yeej, thiab nws yog ib qho nyuaj rau nrhiav seb puas muaj cov dej xau sab hauv hauv kev ua haujlwm li qub. Cov txiaj ntsig kev tshawb fawb pom tau hais tias ntau yam li qub siv los ntawm cov tuam txhab petrochemical muaj teeb meem sab hauv kom sib txawv. Yog vim li cas muaj xws li cov ntaub ntawv nto sealing ntawm lub valve phaj thiab lub rooj zaum valve tsis ua raws li qhov yuav tsum tau siv, kev ua haujlwm raug tsis txaus, lub kaum sab xis ntawm lub phaj valve thiab lub rooj zaum ntawm lub rooj vag valve tsis sib xws, lub sealing nto. qhov dav sib txawv, qhov haum tsis zoo, lub rooj vag tsis nyob hauv qhov chaw, thiab tsis tuaj yeem kaw.
Piv txwv li, rau Z41Y-25, lub sealing nto cov ntaub ntawv code Y yuav tsum xa mus rau lub sealing nto cov ntaub ntawv uas kuj mos hardness nyob rau hauv lub sealing khub, thiab lwm yam sealing nto cov ntaub ntawv uas yuav tsum tau pom tseeb yog tsawg kawg yog hard alloy. Qhov tseeb, qee qhov li qub tsuas yog muaj cov tawv tawv welded rau ntawm ib qho ntawm cov khoom sib khi, thaum lwm qhov sealing nto yog ua los ntawm cov hlau. Tsis ntev tom qab muab tso rau hauv kev siv, sab hauv leakage tshwm sim vim hnav.
Lwm qhov piv txwv yog tias qee lub raj xa dej siv lub wafer-hom npauj npaim valve, thiab cov khoom siv lub rooj zaum valve yog polytetrafluoroethylene. Los ntawm qhov kev xav ntawm kev khiav hauj lwm, cov kev xav tau tsis siab, tag nrho ntawm qhov kub thiab txias, tab sis thaum lub sij hawm sim ua haujlwm, nws tau pom tias muaj coob tus li qub tsis tau kaw nruj nreem, thiab sab hauv toughness, yog li ntawd. lawv tsis tuaj yeem siv ib txwm, thiab thaum kawg yuav tsum tau hloov nrog lub rooj vag li qub. Tom qab dismantling thiab xyuas, nws tau pom tias muaj qhov sib txawv loj ntawm lub phaj valve thiab lub rooj zaum valve hauv lub xeev kaw, thiab txawm tias lub teeb yog pob tshab.
Cov laj thawj yuav muaj raws li hauv qab no! Cov qauv tsim ntawm lub valve sealing khub tsis tsim nyog lossis kev tsim khoom thiab kev sib dhos tsis tau raws li qhov yuav tsum tau ua; lub valve installation tsis yog tsim raws li qhov yuav tsum tau ua, yog li ntawd nws yuav raug quab yuam ntau dhau; Thaum lub sij hawm tsim kho, impurities xws li vuam slag, xuab zeb, thiab hlau chips nkag mus rau hauv lub valve kab noj hniav, cuam tshuam rau sealing nyhuv. Qhov tseeb, qhov ua tau zoo dua thiab qhov tseem ceeb tshaj plaws yog vim li cas tus qauv yuav tsum tsis ua raws li kev tsim khoom, kev thauj mus los lossis kev teeb tsa.
