Iyini ivalvu yebhola enezindlela ezintathu
I-valve yebhola enezindlela ezintathuiyithuluzi lokulawula uketshezi elisebenziseka ngezindlela eziningi elisetshenziswa kabanzi ezinhlelweni zezimboni, zezentengiselwano, kanye nezezindlu. Idizayini yalo eyingqayizivele ivumela ukuphambuka kokugeleza, ukuxuba, noma ukuvala amapayipi. Kulesi sihloko, sizohlolaizimiso zokusebenza, izinhlobo(kufaka phakathiamavalvu ebhola ensimbi engagqwali anezindlela ezintathu, Uhlobo lwe-Y, Uhlobo lwe-L, futhiUhlobo lwe-T), izinhlelo zokusebenza, futhiizinzuzoyalezi valve.
Isimiso Sokusebenza se-aI-Valve Yebhola Enezindlela Ezi-3
I-valve yebhola enezindlela ezintathu iqukethe ibhola elingenalutho, elijikelezayo elinembobo eyodwa noma ezimbili (imigodi) kanye nokuxhumeka kwamapayipi amathathu. Ngokujikelezisa ibhola ngesandla noma nge-actuator, indlela yokugeleza iyaqondiswa kabusha. Kuye ngomklamo we-valve, ingenza okulandelayo:
- Ukugeleza kokuphambukisaphakathi kwezindawo ezimbili zokuphuma.
- Hlanganisa uketshezikusuka ezindaweni ezimbili zokungena ziye endaweni eyodwa yokukhipha.
- Vala ukugelezangokuphelele.
Indawo yebhola inquma indlela yokugeleza. Isibonelo, ukujika kwamadigri angu-90 kungashintsha ukugeleza kusuka kwelinye ichweba kuya kwelinye, kuyilapho ukujika kwamadigri angu-180 kungavimba konke ukugeleza.
