Product Overview
Qhov no flanged rocker check valve yog lub viav vias hom tsis rov qab valve. Nyob rau hauv lub valve, ib tug rocker caj npab txav lub disc mus rau lub viav vias ntawm lub pob khawm. Forward kua siab thawb lub disc qhib kom cov xov xwm dhau mus. Thaum backflow tshwm sim, lub disc kaw cia li los ntawm nws tus kheej qhov hnyav thiab rov qab siab, tiv thaiv cov kua los ntawm ntws rov qab. Tsim los ntawm cov hlau nplaum lub cev thiab cov roj hmab resilient sealing, nws muaj txoj hauv kev zoo thiab tsis tshua muaj dej tsis kam.
Ntsiab nta
Txoj kev ncaj-dhau ntws ua rau cov dej ntws tsis zoo thiab kev poob siab me.
Lub disc swings ntawm rocker pob khawm tus pin rau hloov tau yooj yim qhib thiab kaw, yuav tsum tau me ntsis quab yuam nyob rau hauv pem hauv ntej ntws.
Lub disc kaw cia li nyob rau hauv nws tus kheej qhov hnyav thiab rov qab-flow siab kom tsis txhob rov qab cov dej txav.
Cov qauv yooj yim rau kev kho kom yooj yim ntawm qhov chaw thiab hloov foob.
Ua haujlwm ntseeg tau ntawm cov kav dej kab rov tav, kev ua haujlwm zoo rau cov ntawv loj loj.
Resilient roj hmab rooj zaum muab kaw ntom nti tom qab kaw lub valve.
Daim ntawv thov Scenario
Qhov no rocker check valve feem ntau yog ntsia ntawm cov twj tso kua mis kom tiv thaiv qhov nruab nrab rov qab thiab tiv thaiv cov twj tso kua mis. Nws yog siv dav hauv cov kav dej hauv nroog, cov dej ua haujlwm, cov chaw tso dej, cov chaw kho dej thiab cov kav dej phwj tuaj.
