Hlola i-valve: I-valve yokuhlola yaziwa nangokuthi i-valve yendlela eyodwa noma i-valve yokuhlola, umsebenzi wayo ukuvimbela okuphakathi epayipini Ukubuyela emuva.Ivalvu engezansi yepompo yokuvala amanzi nayo ingeyesigaba sevalvu engabuyi.I-valve ezivula noma ezivale ngokwawo ngokugeleza namandla e-medium ukuvimbela i-medium ukuthi ingabuyeli emuva ibizwa ngokuthi i-valve yokuhlola.Ama-valve okuhlola ayingxenye yama-automatic valves.Amavalvu okuhlola asetshenziswa kakhulu emapayipini lapho okuphakathi kugeleza ohlangothini olulodwa, futhi avumela okuphakathi ukuthi kugelezele ohlangothini olulodwa ukuvimbela izingozi.Ngokwesakhiwo se-valve yokuhlola, ingahlukaniswa ngezinhlobo ezintathu: i-valve yokuhlola isheke, i-valve yokuhlola i-swing kanye ne-valve yokuhlola uvemvane.Ama-valve okuhlola ama-Lift angahlukaniswa abe izinhlobo ezimbili: ama-valve okuhlola aqondile kanye nama-valve okuhlola avundlile.Ama-valve okuhlola i-Swing ahlukaniswe abe izinhlobo ezintathu: i-valve yokuhlola yeqabunga elilodwa, i-valve yokuhlola esebenza kabili kanye ne-valve yokuhlola enamaqabunga amaningi.I-valve yokuhlola uvemvane iyi-valve yokuhlola eqondile.Ama-valve okuhlola okukhulunywe ngenhla angahlukaniswa abe yizinhlobo ezintathu ngendlela yokuxhuma: i-valve yokuhlola enentambo, i-valve yokuhlola ene-flanged kanye ne-valve yokuhlola eshiselwe.
Ukufakwa kwe-valve yokuhlola kufanele kunake lokhu okulandelayo: Ungenzi i-valve yokuhlola isisindo sebhere epayipini, futhi i-valve yokuhlola enkulu kufanele isekelwe ngokuzimela ukuze ingathinteki ukucindezela okukhiqizwa uhlelo lwamapayipi.
Lapho ufaka, naka isiqondiso sokugeleza okuphakathi kufanele kuhambisane nesiqondiso somcibisholo ovotelwe umzimba we-valve.
Ivalvu yokuhlola eqondile yohlobo lokuphakamisa kufanele ifakwe epayipini elime mpo.Ivalvu yokuhlola i-flap evundlile yohlobo lokuphakamisa kufanele ifakwe epayipini elivundlile.
Imingcele yokusebenza eyinhloko ye-valve yokuhlola: Ukucindezela okuzisholo noma izinga lokucindezela: PN1.0-16.0MPa, ANSI CLASS1 50-900, JIS 10-20K, ububanzi bokulinganisa noma i-caliber: DN15-900.
I-NPS 1/4-36, indlela yokuxhuma: i-flange, i-butt welding, intambo, i-socket welding, njll., izinga lokushisa elisebenzayo: -196℃-540℃, i-valve body material: WCB.
ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (3041), CF8M (316), CF3M (316L), Ti, khetha izinto ezahlukene, ama-valve okuhlola angasetshenziswa emanzini, umusi, uwoyela, i-nitric acid, i-acetic acid, i-oxidation Ezocansi imidiya, i-urea neminye imidiya.
