Ama-valve esangofuthiama-valve embulungaama-valve asetshenziswa kakhulu.Lapho ukhetha i-valve yesango noma i-globe valve, kunzima kubasebenzisi abaningi ukwenza isinqumo esifanele.Ngakho-ke uyini umehluko phakathi kwe-valve yembulunga kanye ne-valve yesango, futhi ungayikhetha kanjani ekusetshenzisweni kwangempela?
Ngokuvamile, mayelana nokukhethwa kwama-valve ekwakhiweni kwamapayipi, ama-valve esango avame ukusetshenziswa emithonjeni ye-liquid, futhi ama-valve okumisa asetshenziswa emithonjeni yegesi.Womabili ama-valve embulunga kanye nama-valve esango angama-valve okuvala ayimpoqo.Bobabili basunduza isihlalo se-disc kanye ne-valve ukuze benze uphawu ngokuzungezisa i-valve, esikhundleni sokuncika ekucindezelweni okuphakathi ukuze kuzuzwe uphawu njenge-valve yebhola.Umehluko phakathi kwe-valve yembulunga kanye ne-valve yesango kanye nomehluko phakathi kokusetshenziswa kwazo kanye nobukhulu obuhlukahlukene : Ubude besakhiwo se-valve yesango, okungukuthi, ubude obuphakathi kwezindawo ze-flange bufushane kunaleyo ye-valve yokuvala;ukuphakama kokufakwa nokuphakama kokuvula kwe-valve yokuvala kuncane kune-valve yesango.Nakuba zonke ziyimivimbo ye-angular, ukuphakama kokuvula kwe-valve yokuvala kuyisigamu kuphela se-diameter yegama, isikhathi sokuvula sifushane kakhulu, futhi ukuphakama kokuvula kwe-valve kufana nobubanzi obujwayelekile.
Umehluko ekuqondeni kokugeleza kwe-medium: i-valve yesango i-valve yokuvala indlela emibili, engafinyelela ukubekwa uphawu kuzo zombili izinkomba, futhi asikho isidingo sokuqondisa ukufakwa.I-valve yokuvala inesakhiwo esimise okwe-S.I-valve yokuvala inesidingo sesiqondiso sokugeleza.I-valve yokuvala enobubanzi obuncane obungaphansi kwe-DN200 igeleza isuka ngaphansi kwe-disc iye phezulu kwe-disc, kanti i-valve yokuvala enobubanzi obuncane obungaphansi kwe-DN200 igeleza isuka ngaphezu kwediski iye phezulu. i-valve.Ngaphansi kwe-flap.Kodwa-ke, i-valve yokuvala kagesi isebenzisa indlela yokungena okuvela ngaphezu kwe-valve clack.Njengoba ama-valve amaningi okumisa egeleza esuka ngaphansi kwe-valve flap ukuya phezulu, i-torque yokuvula ye-valve ingancishiswa ngokuphumelelayo, futhi isenzakalo sesando samanzi esibangelwa ukudlidliza kokuvula kwe-valve singagwenywa.Umehluko ekuphikiseni uketshezi lwe-medium: lapho ivuliwe ngokugcwele, yonke indlela yokugeleza kwe-valve yesango idlula, ngaphandle kokuphikiswa, okuphakathi akunakho ukulahlekelwa kokwehla kwengcindezi, futhi i-coefficient yokumelana nokugeleza i-0.08-0.12 kuphela.Ngaphezu kwalokho, i-coefficient yokumelana noketshezi ye-valve yokuvala i-2.4-6, okuyizikhathi ezingu-3-5 i-coefficient yokumelana nokugeleza kwe-valve yesango.Ngakho-ke, i-valve yokuvala ayifanele izimo zokusebenza ezidinga ukulahlekelwa kwengcindezi ephakathi.
Umehluko esakhiweni sendawo yokuvala: indawo yokuvala ye-valve yokumisa i-perpendicular to the pipeline.Uma ivaliwe, uma ukungcola okuphakathi kuhlala phezu kophawu, lapho i-disc ye-valve kanye nesihlalo se-valve yokuvala yenza uphawu, kulula ukulimaza indawo yokuvalwa kwesihlalo se-valve kanye ne-valve yesango Indawo yokuvala inomphumela wokusula lapho isango liyehla, futhi okuphakathi kungagezwa, futhi umonakalo wokungcola okuphakathi nendawo yokubeka uphawu kuncane kakhulu.
