Kuaj valve, tseem hu uaib txoj kev kos valve.Nws lub luag haujlwm tseem ceeb yog tiv thaiv qhov rov qab ntawm qhov nruab nrab thiab tiv thaiv kev nyab xeeb ntawm cov khoom siv thiab cov kav dej.Dej check li qubyog dav siv hauv roj av, tshuaj lom neeg kev lag luam, kev kho dej, hluav taws xob fais fab, metallurgy thiab lwm yam kev lag luam.

Muaj ntau hom kev kos valve, raws li cov qauv sib txawv thiab kev ua haujlwm, tuaj yeem muab faib ua hom nqa, viav vias hom,npauj npaim check valve, pob hom thiab lwm yam.Ntawm lawv, covnqa check valveyog qhov ntau tshaj plaws, uas muaj lub valve nrov plig plawg uas tuaj yeem nqa tau, thiab thaum nruab nrab ntws los ntawm qhov nkag mus rau qhov hluav taws xob, lub valve nrov plig plawg yog topped qhib;Thaum qhov nruab nrab ntws mus rau hauv qhov kev taw qhia rov qab, lub disc raug kaw kom tsis txhob thim rov qab.

Txhawm rau kom ntseeg tau tias kev ua haujlwm ib txwm muajstainless hlau check valvethiab txuas ntxiv nws lub neej kev pabcuam, kev saib xyuas txhua hnub tseem ceeb heev.Nov yog qee qhov kev paub txog kev saib xyuas txhua hnub ntawm cov tshev valve:

1. Kev tshuaj xyuas tsis tu ncua

Txheeb xyuas qhov tshwm sim ntawm daim tshev valve tsis tu ncua kom pom tias muaj cov kab nrib pleb, deformation, corrosion thiab lwm yam tshwm sim.Nyob rau tib lub sijhawm, tshawb xyuas lub foob ntawm lub disc thiab lub rooj kom paub tseeb tias tsis muaj qhov xau.

2. Kev ntxuav

Tsis tu ncua ntxuav sab hauv thiab sab nraud ntawm daim tshev valve kom tshem tawm cov av thiab impurities.Thaum ntxuav, tus neeg saib xyuas nruab nrab yuav tsum tau siv kom tsis txhob siv cov tshuaj corrosive xws li cov kua qaub thiab alkali.

3. Hloov cov khoom puas

Yog hais tias lub valve disc, lub rooj zaum thiab lwm qhov chaw ntawm daim tshev valve pom tias puas los yog hnav hnyav, lawv yuav tsum tau hloov raws sijhawm.Hloov nrog tib qhov tshwj xeeb thiab cov qauv ntawm cov khoom qub kom ntseeg tau tias qhov kev ua haujlwm ntawm lub valve tsis cuam tshuam.

4. Lubrication

Rau qee cov tshev valve uas yuav tsum tau lubricated, ib qho tsim nyog ntawm cov roj lubricating los yog roj yuav tsum tau ntxiv tsis tu ncua kom lub qia thiab lub rooj zaum zoo lubricated.

5.Anti-corrosion kho

Rau cov kab kos valve siv nyob rau hauv ib puag ncig corrosive, coj los tiv thaiv corrosion yuav tsum tau ua, xws li txheej txheej los tiv thaiv corrosion thiab xaiv cov khoom tiv thaiv corrosion.

Los ntawm cov kev ntsuas kev saib xyuas niaj hnub saum toj no, koj tuaj yeem ua kom muaj kev ua haujlwm zoo ntawm daim tshev valve thiab txuas ntxiv lub neej kev pabcuam, thiab muab kev lav zoo rau kev nyab xeeb ntawm cov khoom siv thiab cov kav dej.
