Phapang pakeng tsa valve ea ho hlahloba sekoti le valve ea ho hlahloba flange ke:
- Tšebeliso ea khatello ea hamore ea metsi e fapane:
The thipa e hlahlobang valve e nyane ka boholo, e na le "disc stroke" e khuts'oane, 'me e thusoa ke seliba ho koala valve.
- Papiso ea boholo le boima ba 'mele:
Sephahla sa ho hlahloba sekoti se na le sebopeho se sekhutšoane, boholo bo nyane le boima bo bobebe, bo tlisang boiketlo bo boholo ba ho kenya, ho tšoara, ho boloka le ho hlophisa liphaephe tsa valve, 'me e ka boloka lisebelisoa tse ngata le ho fokotsa litšenyehelo; Flange check valve Sebopeho sa valve se telele, se seholo ebile se boima.
- Tšebeliso ea ho hanyetsa metsi e fapane:
Ho hanyetsa ha valve ea ho hlahloba liphaephe ho nyane, 'me coefficient ea ho hanyetsa mokelikeli ξ ke 2.6 ~ 2.7. Ka keketseho ea bophara ba valve, coefficient ea ho hanyetsa metsi e fokotseha; valve ea ho hlahloba flange e nyenyane, 'me motsoako oa ho hanyetsa mokelikeli ξ ke 1.3 ~ 3, empa tlas'a maemo a tlaase a khatello, valve disc e ke ke ea buloa ka ho feletseng,' me ho hanyetsa mokelikeli ho hoholo. Ho hanyetsa mokelikeli ho eketseha ka ho eketseha ha bophara ba valve.
- Mokhoa oa ho kenya o fapane:
Wafer check valve e ka kenngoa ka holimo kapa ka ho otloloha, 'me boima bo bobebe, kahoo ha ho hlokahale hore u behe tšehetso bakeng sa valve; ho kenngoa ka holimo ha valve ea ho hlahloba flange le li-valve tsa bophara bo boholo li boima 'me li hloka ho beha tšehetso.
- Khatello ea pele e fapane:
Ho buloa ha valve ea ho hlahloba liphaephe ho nyane haholo, 'me disc e ka buloa ka ho feletseng tlas'a phapang e nyenyane ea khatello; khatello ea ho bula ea valve ea ho hlahloba flange e kholo, 'me disc e ka buloa ka ho feletseng tlas'a phapang e khōlō ea khatello.
- Ho tšepahala ha valve ho fapane:
Motlakase oa ho hlahloba sephahla ke sebopeho se feletseng, se bonolo ebile se kopane, matla a ts'ebetso a nyenyane ha valve e koetsoe, khatello ea hamore ea metsi e nyenyane, bophelo ba valve bo bolelele, 'me ho tšepahala ho phahame; matla a maholo a tšusumetso le khatello ea hamore ea metsi ha valve ea ho hlahloba flange e koetsoe e bonolo Ho senya valve.
