Lifting check valve yog hais txog lub valve uas cia li qhib thiab kaw lub disc nyob ntawm qhov ntws ntawm qhov nruab nrab nws tus kheej los tiv thaiv qhov nruab nrab rov qab, tseem hu ua check valve, one-way valve, counterflow valve, thiab back pressure valve. Check valve yog ib qho tsis siv neeg valve. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv qhov nruab nrab rov qab, rov qab twj tso kua mis thiab tsav lub cev muaj zog, thiab tso tawm cov ntim nruab nrab. Kos li qub kuj tseem siv tau rau hauv cov kav dej los muab cov tshuab pabcuam uas lub siab tuaj yeem nce siab tshaj qhov system siab. Kos li qub tuaj yeem muab faib ua viav vias kos li qub (rotating raws li qhov nruab nrab ntawm lub ntiajteb txawj nqus) thiab nqa daim tshev li qub (tsiv raws li axis).
