Kunezinhlobo eziningi zama-valve, futhi ngayinye inezinzuzo zayo kanye nokubi. Nazi izinzuzo nezinkinga ezinkulu ezinhlanu zamavalvu, okuhlanganisa ama-valve esango, ama-butterfly valves, ama-ball valves, ama-globe valves nama-plug valves. Ngethemba ukukusiza.
I-valve yeqhude: isho ivalve ejikelezayo evalekile emise okwe-plunger. Ngemva kokuzungezisa okungu-90°, imbobo yesiteshi kupulaki yevalvu ixhunywa noma ihlukaniswe nembobo yesiteshi emzimbeni wevalvu ukuze kuzuzwe ukuvula noma ukuvala. Ukuma kwepulaki ye-valve kungaba yi-cylindrical noma i-conical. Isimiso ngokuyisisekelo sifana naleso se-valve yebhola. I-valve yebhola ithuthukiswa ngesisekelo se-valve yepulaki. Isetshenziselwa ikakhulukazi ukumba i-oilfield, futhi ibuye isetshenziswe embonini ye-petrochemical.
inzuzo:
①Isetshenziselwa ukusebenza okuvamile, ukuvula nokuvala okusheshayo nokulula.
②Ukumelana noketshezi kuncane.
③ Elula, encane, isisindo esincane, kulula ukuyinakekela.
④Ukusebenza okuhle kokuvala.
⑤ Ngokuncike ekukhawulweni kwesiqondiso sokufaka, isiqondiso sokugeleza se-medium singaba ngokunganaki.
⑥Akukho ukudlidliza nomsindo ophansi.
isici:
①Ikhava sikhulu kakhulu, futhi itorque ewumphumela inkulu kakhulu futhi ayinwebeki ngokwanele.
②Isisindo somzimba siyathinteka, futhi izinga lilinganiselwe.
③Ekusetshenzisweni kwangempela, uma kusetshenziswa i-valve enkulu, kufanele kusetshenziswe isakhiwo sepulaki esihlanekezelwe, esizothinta kalula umphumela wokuvala
