Silent check valve thaum tsis muaj xov xwm ntws los ntawm lub cev valve, lub valve nrov plig plawg nyob rau hauv lub caij nplooj ntoos hlav caij nplooj ntoos hlav quab yuam, ib txwm nyob rau hauv lub xeev kaw. Lub valve qhib thiab kaw thiab qhov loj ntawm qhov qhib℃yog txiav txim siab los ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov nkag thiab qhov hluav taws xob kawg ntawm lub valve. Yog tias qhov siab ntawm qhov kawg ntawm qhov nkag siab siab tshaj qhov sib npaug ntawm qhov siab ntawm qhov hluav taws xob kawg thiab lub caij nplooj ntoos hlav quab yuam, lub valve qhib. Tsuav muaj qhov sib txawv ntawm lub siab, lub valve yeej ib txwm nyob rau hauv lub xeev qhib, nrog rau qhov loj ntawm qhov sib txawv ntawm lub siab kuj txiav txim siab qhov loj ntawm lub valve qhib degree. Yog tias qhov sib npaug ntawm qhov siab ntawm qhov hluav taws xob kawg thiab lub caij nplooj ntoos hlav quab yuam ntau dua qhov siab ntawm qhov kawg ntawm qhov nkag, lub valve raug kaw thiab ib txwm nyob hauv lub xeev kaw.
Vim qhov qhib thiab kaw ntawm lub valve yog nyob rau hauv lub zog dynamic tshuav nyiaj li cas, tsis hais lub inlet sab ntawm cov xov xwm siab hloov, lub valve txav smoothly, thiab tsis muaj suab nrov, tsis muaj kev ruaj ntseg tsis ua hauj lwm.
