Mtengo wa CHV504
Ma valve osagwiritsa ntchito slam, omwe amadziwikanso kuti silent check valves, ali ndi pistoni yofupikitsa ndi kasupe yemwe amatsutsana ndi kayendedwe ka pistoni poyenda. Sitiroko yayifupi ya valavu yopanda slam ndi kasupe imalola kuti itseguke ndikutseka mwachangu, kuchepetsa kugunda kwamphamvu kwa nyundo yamadzi ndikupeza dzina loti silent check valve.
Ntchito:
Cholinga chachikulu ndicho kugwiritsidwa ntchito m'mapaipi omwe amafunikira kuwongolera komwe kukuyenda kwamadzimadzi komanso kuchepetsa phokoso. Madera ake ogwiritsira ntchito akuphatikiza koma osawerengeka ku: machitidwe a mapaipi mumayendedwe operekera madzi, ngalande, makampani opanga mankhwala, makampani opanga mankhwala, mafakitale azakudya, ndi magawo ena.
Ntchito yochepetsera phokoso: Ikhoza kuchepetsa mphamvu ndi phokoso lopangidwa ndi madzimadzi pamene valve yatsekedwa, ndi kuchepetsa kugwedezeka ndi phokoso la dongosolo la mapaipi.
Yang'anani ntchito: Itha kulepheretsa kubwereranso kapena kubwereranso kwamadzimadzi, kuonetsetsa kuti ntchito yapaipi ikugwira ntchito bwino komanso yotetezeka.
