Ukushisa okusebenzayo kwe-valve kunqunywa yimpahla ye-valve.Izinga lokushisa lezinto ezisetshenziswa kakhulu kuma-valve limi kanje:
I-valve yokusebenza kwezinga lokushisa
I-valve yensimbi empunga: -15 ~250℃
I-valve yensimbi ethambile: -15℃ 250℃
I-valve yensimbi ye-Ductile: -30 ~ 350℃
I-valve yensimbi ye-nickel ephezulu: izinga lokushisa eliphakeme kakhulu lokusebenza ngu-400 ℃
I-Carbon steel valve: -29~450℃, izinga lokushisa elinconyiwe t<425℃ ku-JB/T3595-93 standard
I-1Cr5Mo, i-valve yensimbi ye-alloy: izinga lokushisa eliphakeme kakhulu lokusebenza ngu-550 ℃
I-12Cr1MoVA, i-alloy steel valve: izinga lokushisa eliphakeme kakhulu lokusebenza ngu-570 ℃
1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti valvu yensimbi engenasici: -196~600℃
I-valve ye-alloy yethusi: -273℃ ~250℃
Ivalvu yepulasitiki (inayiloni): izinga lokushisa eliphakeme kakhulu lokusebenza ngu-100 ℃
I-valve yepulasitiki (i-polyether ene-chlorinated): izinga lokushisa eliphakeme lokusebenza 100 ℃
I-valve yepulasitiki (i-polyvinyl chloride): izinga lokushisa eliphezulu lokusebenza 60 ℃
I-valve yepulasitiki (polytrifluorochlorethylene): -60 ~ 120 ℃
Ivalvu yepulasitiki (PTFE): -180℃ ~150℃
I-valve yepulasitiki (i-valve yenjoloba yemvelo ye-diaphragm): Izinga lokushisa eliphakeme lokusebenza ngu-60℃
I-valve yepulasitiki (irabha ye-nitrile, i-valve ye-diaphragm ye-neoprene): izinga lokushisa eliphezulu lokusebenza ngu-80 ℃
I-valve yepulasitiki (i-fluorine rubber diaphragm valve): izinga lokushisa eliphakeme kakhulu lokusebenza ngu-200 ℃
Uma irabha noma ipulasitiki isetshenziselwa ukwakhiwa kwe-valve, ukumelana nezinga lokushisa kwerabha nepulasitiki kuyoba khona
Amavalvu e-Ceramic, ngenxa yokungazweli kahle kwezinga lokushisa, ngokuvamile asetshenziswa ezimweni zokusebenza ezingaphansi kuka-150°C.Muva nje, kuvele i-valve ye-ceramic esebenza kahle kakhulu, ekwazi ukumelana namazinga okushisa angaphansi kuka-1000°C.
Amavalvu engilazi awakwazi ukumelana nezinga lokushisa eliphansi futhi ngokuvamile asetshenziswa ezimweni zokusebenza ezingaphansi kuka-90°C.
Ukumelana nokushisa kwe-valve koqweqwe lwawo kunqunyelwe izinto zendandatho yokuvala, futhi izinga lokushisa eliphezulu lokusebenza alidluli ku-150 ° C.
Izinto ezibonakalayo ze-valve zifaka phakathi: C carbon steel, I 1Cr5Mo chromium molybdenum steel, H Cr13 series steel stainless, K malleable cast iron, L aluminium alloy, P 0Cr18Ni9 series steel stainless, PL 00Cr19Ni10 series steel stainless, Q 02C iron2 series, Q 02C iron2 insimbi engagqwali, uchungechunge lwe-RL 00Cr17Ni14Mo2 Insimbi engagqwali, ipulasitiki ye-S, i-T yethusi nengxubevange yethusi, i-Ti titanium ne-titanium alloy, i-V chromium molybdenum vanadium steel, insimbi eyinsimbi engu-Z empunga.
