Los ntawm kev tshuaj xyuas ntawm cov qauv hauv paus ntsiab lus ntawm cov kav dej ruaj khov pob valve, pom tias txoj cai sealing zoo ib yam, siv lub hauv paus ntsiab lus "piston effect", thiab tsuas yog cov qauv sealing txawv.
Valve nyob rau hauv daim ntawv thov ntawm qhov teeb meem yog manifested nyob rau hauv txawv degrees, sib txawv cov ntaub ntawv ntawm to, raws li lub hauv paus ntsiab lus ntawm sealing qauv thiab installation thiab kev tsim kho zoo tsom xam, qhov ua rau ntawm valve leakage yog cov nram qab no yam.
1. Valve installation thiab kev tsim kho zoo yog qhov laj thawj tseem ceeb
Nyob rau hauv lub installation kev tsim kho tsis xyuam xim rau lub valve sealing nto thiab sealing lub nplhaib tiv thaiv, sealing nto puas;Kev teeb tsa tiav, lub raj xa dej thiab lub tshuab valve tsis ua tiav, tsis huv, hauv kev ua haujlwm muaj vuam slag lossis gravel daig ntawm lub pob thiab lub nplhaib sib khi, ua rau kev sib khi tsis ua haujlwm.Nyob rau hauv cov ntaub ntawv no, thaum muaj xwm ceev, lub upstream sealing nto yuav tsum tau txhaj ib ntus nrog tus nqi tsim nyog ntawm sealant los txo cov to, tab sis tsis tuaj yeem daws qhov teeb meem, yog tias tsim nyog, lub valve sealing nto thiab sealing lub nplhaib yuav tsum tau hloov.
2. Valve mechanical processing, sealing nplhaib khoom, thiab sib dhos zoo vim li cas
Txawm hais tias cov qauv valve yog qhov yooj yim, nws yog qhov kev thov siab rau cov khoom siv ua haujlwm zoo, nws cov kev ua haujlwm ncaj qha cuam tshuam rau kev sib khi.Foob lub nplhaib lub nplhaib thiab lub nplhaib lub rooj sib dhos tshem tawm thiab txhua lub nplhaib ntawm qhov chaw yuav tsum tau xam kom raug, qhov roughness ntawm qhov chaw kom tsim nyog.Tsis tas li ntawd, kev xaiv cov khoom siv foob kuj tseem ceeb heev, tsis tsuas yog xav txog corrosion thiab hnav tsis kam, tab sis kuj xav txog nws elasticity thiab nruj.Yog tias nws yog mos heev, nws yuav cuam tshuam rau kev tu tus kheej;yog tias nws nyuaj heev, nws yuav yooj yim tawg.
3. Kev xaiv tsim nyog raws li daim ntawv thov thiab kev ua haujlwm
Txawv sealing kev ua tau zoo thiab sealing qauv ntawm lub valve siv lub sijhawm sib txawv, tsuas yog lub sijhawm sib txawv los xaiv lub valve sib txawv, kom tau txais cov txiaj ntsig zoo tshaj plaws.Nyob rau hauv cov ntaub ntawv ntawm West-East gas pipeline, piv txwv li, tsau pipeline pob li qub nrog ob-directional sealing yuav tsum tau xaiv kom deb li deb li sai tau (tshwj tsis yog rau orbital pob li qub nrog yuam sealing, uas yog kim dua).Txoj kev no, yog tias lub foob sab sauv puas lawm, lub foob hauv qab tseem tuaj yeem ua haujlwm.Lub pob valve raug kaw yuav tsum raug xaiv yog tias yuav tsum muaj kev ntseeg siab tiag tiag.
4. Rau li qub uas muaj kev sib khi sib txawv, kev ua haujlwm sib txawv, kev saib xyuas, thiab kev pabcuam yuav tsum tau siv.
Rau cov li qub uas tsis muaj cov dej xau, lub valve tuaj yeem sau nrog qee cov roj ua ntej thiab tom qab txhua qhov kev ua haujlwm lossis txhua 6 lub hlis hauv ib qho me me ntawm cov qia thiab cov ntsaws ruaj ruaj rau qhov chaw nres nkoj, thiab tsuas yog nyob rau hauv rooj plaub uas tau tshwm sim los yog tsis tuaj yeem kaw tag nrho. tus nqi tsim nyog ntawm sealant txhaj.Vim yog lub siab viscosity ntawm lub sealant, yog tias lub valve tsis nquag ntim nrog sealant, nws yuav cuam tshuam rau kev tu tus kheej ntawm lub ntsej muag kheej kheej, feem ntau cuam tshuam, nqa qee qhov me me grit thiab lwm yam av ntawm lub foob kom ua rau xau.Rau li qub nrog ob txoj kev foob, yog tias qhov chaw muaj kev nyab xeeb tau tso cai, lub siab ntawm lub valve yuav tsum raug tso tawm mus rau xoom, kom ntseeg tau tias kev sib khi.
