Iyini i-Check Valve: Umhlahlandlela Ophelele Wohlobo Nejwayelekile.

Hlola Ukubuka Konke Kwe-Valve

I-valve yokuhlola iyi-valve ezenzakalelayo esebenzisa umfutho woketshezi kanye nesisindo sediski ukuvimbela ukugeleza okubuyela emuva. Eyaziwa nangokuthi i-valve engabuyi, enendlela eyodwa, i-reflux, noma i-isolation, umsebenzi wayo oyinhloko ukuqinisekisa ukugeleza okuqondisayo ukuvikela izinhlelo zamapayipi ekulimaleni kokugeleza emuva.

Indlela Ama-Check Valve Asebenza Ngayo

Ukugeleza phambili: Ukucindezela koketshezi kuphakamisa idiski, okuvumela ukuthi idlule.

Ukugeleza okuphambene: Idiski ivala ngokucindezela kwamandla adonsela phansi/uketshezi, ivimba imidiya.

Izingxenye Eziyinhloko Zama-Check Valve

Izingxenye ezibalulekile zifaka:

Umzimba weValve: Amapayipi axhumanisayo ekheyisini langaphandle

Idiski: Ingxenye yeselula evumela ukulawula ukugeleza

Isihlalo: Yakha indawo yokuvala enediski

Intwasahlobo: Iphoqa ukuvalwa kwediski (ngezinhlobo ezisizwa yintwasahlobo)

Hlola Uphawu Lwevalvu Kumdwebo We-PID

Ukuqonda Uphawu Lwe-Check Valve

1.Umbuthano: Imele umzimba we-valve.

2.Umcibisholo noma Umugqa Ovundlile: Kubonisa indlela yokugeleza. Lokhu kubalulekile ekufakweni, njengoba kuqinisekisa ukuthi ivalvu ibekwe kahle ngaphakathi kohlelo.

3.Izaziso ezengeziwe: Ngezinye izikhathi, izimpawu ezengeziwe noma amalebula angase ahambisane nophawu ukuze anikeze ulwazi olwengeziwe, njengosayizi wevalvu, izinto zokwakha, noma isilinganiso sengcindezi.

Hlola Amazinga Okuklama Amavalvu
