Iyini ivalvu yokuhlola i-piston yensimbi ehlanganisiwe?

I-valve yokuhlola i-piston yensimbi ephonsweminaIklanyelwe ukuvimbela ukuguqulwa kokugeleza ohlelweni lwamapayipi. Ivame ukusetshenziswa ezinhlelweni zamapayipi lapho amavalvu embulunga esetshenziswa khona njengevalvu yokulawula ukugeleza. Anezindawo zokuhlala ezifanayo namavalvu embulunga. Amavalvu okuhlola ukuphakama afanele ukufakwa emigqeni evundlile noma eqondile enokuhamba okuphezulu.

Zinconywa ukuthi zisetshenziswe ngomusi, umoya, igesi, amanzi, kanye nemigqa yomhwamuko enesivinini esikhulu sokugeleza. Amavalvu okuhlola ukuphakama avame ukwakhiwa ngesiphethu, avaliwe ngokuzenzakalelayo, adinga ingcindezi eyengeziwe ukuvula umnyango wawo nokuvumela uketshezi ukuthi ludlule.

Ivalvu yokuhlola i-piston yensimbi ehlanganisiwe iyivalvu evimbela umugqa wokumunca ukuthi ungasebenzi ungenalutho, isib. ngemva kokuba iphampu imisiwe. Ngakho-ke, uku-primer iphampu ngaphambi kokuthi iqale kabusha akusadingeki. Ama-valvu okuhlola okuphakamisayo

Izici eziyinhloko ze-Cast steel piston check valve

Izici kanye nezinzuzo zeI-valve yokuhlola i-piston yensimbi ephonswe

1) Ukuvala okusheshayo nokusebenza okuzinzile: ukushaywa okuncane kwediski ye-valve kwenza kube nokwenzeka ukuvala okusheshayo, idiski elayishwe ngesipili iyinto enhle kakhulu, yenza ukuvala kusheshe futhi kuthembeke.
2) Ukuvala okuzenzakalelayo ngediski elayishwe entwasahlobo.
3) Ukwakhiwa okulula kakhulu nokugcinwa okulula.
