Indlela okusebenza ngayo ama-valve okulawula, ama-globe valve, ama-gate valve kanye nama-check valve

I-valve yokulawula, ebizwa nangokuthi i-valve yokulawula, isetshenziselwa ukulawula usayizi woketshezi. Lapho ingxenye elawulayo ye-valve ithola isignali yokulawula, isiqu se-valve sizolawula ngokuzenzakalelayo ukuvulwa nokuvalwa kwe-valve ngokwesignali, ngaleyo ndlela silawule izinga lokugeleza koketshezi kanye nokucindezela; ngokuvamile kusetshenziselwa ukushisa, igesi, i-petrochemical kanye neminye imipayipi.

I-valve yokumisa, eyaziwa nangokuthi i-stop valve, ingavala ngokuphelele indawo yokukhipha isihlalo se-valve ngokusebenzisa ingcindezi ngokujikeleza isiqu se-valve, ngaleyo ndlela ivimbele ukugeleza koketshezi; ama-stop valve avame ukusetshenziswa kugesi yemvelo, igesi encibilikisiwe, i-sulfuric acid kanye neminye igesi ebolile kanye namapayipi oketshezi.

I-valve yesangokufana nesango. Ngokuzungezisa isiqu sevalvu, ipuleti lesango lilawulwa ukuthi lihambe phezulu naphansi ukuze lilawule uketshezi. Amasongo okuvala kuzo zombili izinhlangothi zepuleti lesango angavala ngokuphelele ingxenye yonke. Ivalvu yesango ingavulwa ngokuphelele futhi ivalwe ngokuphelele, futhi ayikwazi ukusetshenziswa ukulawula ukugeleza. Amavalvu esango asetshenziswa kakhulu njengamadivayisi okuvimba emanzini ompompi, indle, imikhumbi kanye neminye imipayipi.
 

I-valve yokuhlola i-swingithembele ekucindezelweni koketshezi ukuvula isembozo sevalvu. Uma ingcindezi yoketshezi olusemapayipini okungena kanye nawokuphuma kwevalvu ilinganisiwe, isembozo sevalvu singavaleka ngamandla aso adonsela phansi ukuze sivimbele uketshezi ukuthi ludlule. Umsebenzi waso oyinhloko ukuvimbela uketshezi ukuthi lugeleze emuva. Ukugeleza, kungokwesigaba sevalvu ezenzakalelayo; ikakhulukazi esetshenziswa kumapayipi kaphethiloli, amakhemikhali, emithi kanye neminye.
