Asebenza kanjani ama-valve alawulayo, ama-globe valves, ama-valve esango namasheke

I-valve yokulawula, ebizwa nangokuthi i-valve yokulawula, isetshenziselwa ukulawula ubukhulu boketshezi.Lapho ingxenye elawulayo ye-valve ithola isignali elawulayo, i-valve stem izolawula ngokuzenzakalelayo ukuvulwa nokuvalwa kwe-valve ngokusho kwesignali, ngaleyo ndlela ilawula izinga lokugeleza kwamanzi nokucindezela;evame ukusetshenziselwa ukushisa, igesi, i-petrochemical namanye amapayipi.

I-valve yokumisa, eyaziwa nangokuthi i-stop valve, ingavala ngokuphelele indawo yokuhlala ye-valve ngokufaka ingcindezi ngokuzungezisa isiqu se-valve, ngaleyo ndlela ivimbele ukugeleza koketshezi;amavalvu okumisa ngokuvamile asetshenziswa kugesi yemvelo, igesi ewuketshezi, i-sulfuric acid nakwamanye amapayipi egesi agqwalayo kanye namapayipi awuketshezi.

I-valve yesangokufana nesango.Ngokuzungezisa isiqu se-valve, ipuleti lesango lilawulwa ukuthi lihambe liye phezulu naphansi ukuze lilawule uketshezi.Izindandatho zokuvala ezinhlangothini zombili zepuleti lesango zingavala ngokuphelele sonke isigaba.I-valve yesango ingavulwa ngokugcwele futhi ivalwe ngokugcwele, futhi ayikwazi ukusetshenziselwa ukulawula ukugeleza.Ama-valve esango asetshenziswa kakhulu njengemishini yokucabela emanzini kampompi, indle, imikhumbi namanye amapayipi.
 

I-valve yokuhlola i-swingincike ekucindezelweni koketshezi ukuze uvule ikhava yevalvu.Lapho umfutho woketshezi olusesikhaleni se-valve namapayipi aphumayo ulinganisela, isembozo sevalvu singavala ngokwaso amandla adonsela phansi ukuze kuvinjwe uketshezi ukuba lungadluli.Umsebenzi wawo oyinhloko ukuvimbela uketshezi ukuthi lungabuyeli emuva.Ukugeleza, kungokwesigaba se-automatic valve;ikakhulukazi esetshenziswa petroleum, amakhemikhali, imithi kanye namanye amapayipi.
