Lub discnpauj npaim check valveyog disc-zoo li tus thiab rotates nyob ib ncig ntawm lub rotating ncej ntawm lub valve rooj channel. Vim hais tias cov channel hauv lub valve yog streamlined, cov dej tsis kam yog me dua li ntawmlifting npauj npaim check valve. Nws yog qhov tsim nyog rau lub sijhawm loj-ntev nrog tus nqi qis qis thiab tsis tshua muaj kev hloov pauv, tab sis tsis haum rau pulsating txaus. Nws sealing kev ua tau zoo tsis zoo li covlifting check li qub. Npauj Npaim kos li qub tau muab faib ua ib hom-disc, ob-disc hom thiab ntau-disc hom. Peb hom no feem ntau muab faib raws li lub valve txoj kab uas hla. Lub hom phiaj yog txhawm rau tiv thaiv qhov nruab nrab los ntawm kev txwv tsis pub ntws los yog rov qab thiab ua kom tsis muaj zog ntawm qhov cuam tshuam hydraulic.
