Kev tshuaj xyuas xov
Rau threaded Cheebtsam:
Xov profile
Xov tob
Kev sib xyaw ua ke
Txheej tshuaj xyuas
Kev tiv thaiv txheej plays lub luag haujlwm tseem ceeb hauv kev txuas lub neej kev pabcuam valve.
Tom qab kev kho saum npoo thiab txheej txheej, cov khoom siv tshuaj xyuas txheej txheem.
Surface Preparation Check
Xyuas kom tseeb tias cov chaw raug ntxuav kom zoo ua ntej txheej txheej.
Txheej Thickness Ntsuas
Random kuaj yog ntsuas kom paub meej tias txheej thickness sib xws.
Txheej Txheej
Kev soj ntsuam xyuas kom tiav cov kev pab cuam ntawm:
Valve lub cev
Flanges
Nyuaj - mus rau - mus txog thaj chaw
Kev tshuaj xyuas adhesion
Txheej adhesion raug tshuaj xyuas kom txo tau qhov kev pheej hmoo ntawm cov txheej txheem ntxov ntxov thaum lub caij tsheb thauj mus los thiab kev teeb tsa.
Kev Ntsuas Siab
Kev ntsuas siab yog ua ua ntej ua zaub mov xa tuaj kom paub tseeb tias kev sib khi thiab kev ua haujlwm siab.
Shell Pressure Test
Qhov kev sim no txheeb xyuas qhov kev ncaj ncees ntawm lub cev lub cev thiab lub siab - muaj cov khoom.
Lub valve yog raug rau qhov ntsuas qhov ntsuas kom paub tseeb tias tsis muaj qhov pom pom los ntawm lub cev.
Seat Leakage Test
Qhov kev sim no txheeb xyuas qhov kev sib khi ua haujlwm thaum lub valve nyob hauv qhov chaw kaw.
Lub hom phiaj yog los xyuas kom meej lub rooj zaum thiab cov khoom sib khi ua haujlwm raws li qhov xav tau.
Kev Tshawb Fawb Kev Ua Haujlwm
Valve qhib thiab kaw ua haujlwm raug txheeb xyuas kom ntseeg tau tias kev txav mus los thiab ua haujlwm kom raug.
Kev tshuaj xyuas cov khoom kawg
Ua ntej packing, cov khoom tiav raug soj ntsuam zaum kawg.
Kev txheeb xyuas qhov tshwm sim
Kev tshuaj xyuas muaj xws li:
Deg mob
Txheej tsos
Khoom huv si
