Kuaj Valve: Tso cai tsuas yog unidirectional ntws ntawm nruab nrab. Nws cia li kaw thaum qhov nruab nrab ntws mus rau qhov kev taw qhia tawm tsam kom tsis txhob thim rov qab. Feem ntau siv nyob rau hauv lub twj tso kua mis, boiler systems, thiab lwm yam, los tiv thaiv cov khoom reversal los yog backflow ntawm nruab nrab.
Relief Valve: Tsis siv neeg qhib kom tso siab thaum lub kaw lus siab tshaj qhov teeb tsa tus nqi, tiv thaiv kev puas tsuaj rau cov khoom siv lossis cov kav dej vim yog overpressure. Nws cia li kaw thaum lub siab rov qab mus rau qhov qub.

FAQ
Thaum twg kuv yuav tsum siv lub check valve?
Raws li cov cuab yeej muaj kev nyab xeeb, lub tshev valve yog qhov tseem ceeb thaum muaj kev sib cais ntawm thaj tsam ntawm kev kub siab thiab ib qho ntawm qhov tsis tshua muaj siab. Ib tug xws li Circuit Court yog lub accumulator, uas feem ntau ua hauj lwm siv ob daim tshev li qub.
Dab tsi yog peb hom ntawm lub siab nyem li qub?
Peb hom yooj yim ntawm lub siab-relief li qub yog covua haujlwm- hom siab nyem valve, piston- hom siab nyem valve, diaphragm- hom siab nyem valve.
Thaum twg koj yuav siv lub siab nyem valve?
Lub siab nyem li qub yog qhov yuav tsum tau uanyob rau hauv cov hlab ntsha siab, chav tshuab, cov khoom siv tshuaj lom neeg, thiab kev ua haujlwm roj thiab roj uas muaj kev kub ntxhov ntau ua rau muaj kev pheej hmoo loj. Cov ntawv thov no feem ntau koom nrog siab - cov tshuab hluav taws xob uas qhov kev ua tsis tiav tuaj yeem ua rau muaj kev puas tsuaj loj.
