I. Vim li casnpauj npaim valvecov qauv tseem ceeb?
Tus qauv no qhia txog kev tsim cov npauj npaim valve thiab kev ntsuam xyuas uas txhua lub valve yuav tsum dhau. Yog tsis muaj cov qauv no, kev ruaj ntseg ntawm lub kaw lus yuav tsis tuaj yeem lav tau. Cov valve yuav tsis tuaj yeem sib dhos, cov khoom sib txuas yuav tsis sib xws, thiab tag nrho cov kav dej yuav raug kev pheej hmoo tsis tsim nyog.
Tus qauv qhia txog lub qhov dej npauj npaim uas koj ua raws li txiav txim siab txog txoj kev sib txuas flange, qib siab thiab qib khoom siv. Qhov no txhais tau tias cov kws ua haujlwm yuav tsum phim txhua tus qauv ntawm lub qhov dej npauj npaim rau qhov siab, ntws thiab nruab nrab ntawm lub kaw lus kom ntseeg tau tias txhua yam ua haujlwm zoo.
Tsab xov xwm no tsom mus rau ntau tus qauv ISO npauj npaim valve thiab piav qhia lawv kom meej:
