High Performance V Pob Valve
Cov ntsiab lus
V txiav muaj qhov hloov pauv loj thiab sib npaug feem pua ntawm cov yam ntxwv, ua kom muaj kev ruaj khov ntawm kev siab thiab ntws.
Cov qauv yooj yim, ntim me me, lub teeb yuag, du ntws channel.
Muab wrth loj txiv ntoo elastic tsis siv neeg cov qauv them nyiaj kom zoo tswj lub ntsej muag sealing ntawm lub rooj zaum thiab ntsaws thiab paub zoo sealing kev ua tau zoo. Lub eccentric plug thiab lub rooj zaum qauv tuaj yeem txo qhov hnav.
V txiav ua rau wedge shearing quab yuam wrth lub rooj kom kaw tawm cov xov xwm uas muaj fibers. Nws yog qhov tshwj xeeb tshaj yog tsim rau kev qhib thiab tswj kev tshaj tawm ntawm cov viscosity siab thiab cov xov xwm uas muaj fiber ntau thiab granules.
