I-valve yokuhlola: I-valve yokuhlola yaziwa nangokuthi i-valve yendlela eyodwa noma i-valve yokuhlola, umsebenzi wayo ukuvimbela i-medium epayipini Ukugeleza Kokubuyela Emuva. I-valve engezansi yepompo yokuvala amanzi nayo ingesigaba se-valve engabuyi. I-valve evula noma evala yodwa ngokugeleza namandla e-medium ukuvimbela i-medium ukuthi igeleze emuva ibizwa ngokuthi i-valve yokuhlola. Ama-valve okuhlola angaphansi kwesigaba sama-valve azenzakalelayo. Ama-valve okuhlola asetshenziswa kakhulu emapayipini lapho i-medium igeleza khona ohlangothini olulodwa, futhi avumela kuphela i-medium ukuthi igeleze ohlangothini olulodwa ukuvimbela izingozi. Ngokwesakhiwo se-valve yokuhlola, ingahlukaniswa ngezinhlobo ezintathu: i-valve yokuhlola yokuphakamisa, i-valve yokuhlola yokushintsha kanye ne-valve yokuhlola ye-butterfly. Ama-valve okuhlola okuphakamisa angahlukaniswa ngezinhlobo ezimbili: ama-valve okuhlola aqondile kanye nama-valve okuhlola avundlile. Ama-valve okuhlola okushintsha ahlukaniswe ngezinhlobo ezintathu: i-valve yokuhlola eneqabunga elilodwa, i-valve yokuhlola esebenza kabili kanye ne-valve yokuhlola enamaqabunga amaningi. I-valve yokuhlola ye-butterfly iyi-valve yokuhlola eqondile. Ama-valve okuhlola ashiwo ngenhla angahlukaniswa ngezinhlobo ezintathu ngesimo sokuxhuma: i-valve yokuhlola enezintambo, i-valve yokuhlola e-flanged kanye ne-valve yokuhlola ehlanganisiwe.
Ukufakwa kwevalvu yokuhlola kufanele kunake okulandelayo: Ungenzi ivalvu yokuhlola ibe yisisindo esithwalayo epayipini, futhi ivalvu yokuhlola enkulu kufanele isekelwe ngokuzimela ukuze ingathinteki yingcindezi ekhiqizwa uhlelo lwamapayipi.
Uma ufaka, naka isiqondiso sokugeleza okuphakathi kufanele sihambisane nesiqondiso somcibisholo ovotelwe umzimba wevalvu.
Ivalvu yokuhlola evundlile yohlobo lokuphakamisa kufanele ifakwe epayipini eliqondile. Ivalvu yokuhlola evundlile yohlobo lokuphakamisa kufanele ifakwe epayipini eliqondile.
Amapharamitha okusebenza ayinhloko evalvu yokuhlola: Ingcindezi noma izinga lokucindezela elijwayelekile: PN1.0-16.0MPa, ANSI CLASS1 50-900, JIS 10-20K, ububanzi noma i-caliber elinganiselwe: DN15-900.
I-NPS 1/4-36, indlela yokuxhuma: i-flange, i-butt welding, intambo, i-socket welding, njll., izinga lokushisa elifanele: -196℃-540℃, izinto zomzimba we-valve: WCB.
ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (3041), CF8M (316), CF3M (316L), Ti, khetha izinto ezahlukene, ama-check valve angasetshenziswa emanzini, umusi, uwoyela, i-nitric acid, i-acetic acid, i-oxidation Sexual media, i-urea kanye nezinye izinto.
