Hoʻoholo ʻia ka mahana hana o ka valve e ka mea o ka valve.ʻO ka mahana o nā mea hoʻohana maʻamau no nā kiwi penei:
ʻO ka wela hana o ka valve
Kiwi hao hina hina: -15～250 ℃
Kiwi hao malleable: -15 ~ 250 ℃
Kiwi hao hao: -30~350 ℃
ʻO ke kiʻekiʻe nickel cast iron valve: ʻo ka mahana hana kiʻekiʻe loa he 400 ℃
ʻO ka pahu kila kalapona: -29 ～ 450 ℃, ka mahana i manaʻo ʻia t<425 ℃ ma JB/T3595-93 maʻamau
1Cr5Mo, pahu kila kila: ʻo ka mahana hana kiʻekiʻe loa he 550 ℃
12Cr1MoVA, pahu kila kila: ʻo ka mahana hana kiʻekiʻe loa he 570 ℃
1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti kiwi kila kila: -196～600℃
ʻO ka pahu hao keleawe: -273 ~ 250 ℃
ʻO ka valve plastik (nylon): ʻo ka mahana hana kiʻekiʻe loa he 100 ℃
ʻO ka pāpaʻi paʻa (polyether chlorinated): ka wela hana kiʻekiʻe 100 ℃
ʻO ka pāpaʻi paʻa (polyvinyl chloride): ka wela hana kiʻekiʻe he 60 ℃
ʻO ka pāpaʻi paʻa (polytrifluorochloroethylene): -60～120 ℃
ʻO ka pahu palaki (PTFE): -180 ~ 150 ℃
ʻO ka pāpaʻi paʻa (pilikia diaphragm valve maoli): ʻO ka mahana hana kiʻekiʻe he 60 ℃
ʻO ka pahu palaki (nitrile rubber, neoprene diaphragm valve): ʻo 80 ℃ ke kiʻekiʻe o ka mahana hana
ʻO ka pahu palaki (fluorine rubber diaphragm valve): ʻo ka mahana hana kiʻekiʻe loa he 200 ℃
Ke hoʻohana ʻia ka lāʻau a i ʻole ka plastic no ka uhi ʻana i ka valve, e lanakila ka pale wela o ka lāʻau a me ka plastic
Hoʻohana maʻamau ʻia nā kīwaha seramika, no ka maikaʻi ʻole o ka wela, i nā kūlana hana ma lalo o 150 ° C.I kēia mau lā, ua ʻike ʻia kahi valve ceramic super-performance, hiki ke kū i nā wela kiʻekiʻe ma lalo o 1000 ° C.
He haʻahaʻa haʻahaʻa ka wela o nā pahu aniani a hoʻohana mau ʻia i nā kūlana hana ma lalo o 90°C.
ʻO ka pale wela o ka pahu enamel i kaupalena ʻia e ka mea o ke apo sealing, a ʻaʻole ʻoi aku ka nui o ka mahana hana ma mua o 150 ° C.
ʻO nā mea kino o ka valve ka mea nui: C carbon steel, I 1Cr5Mo chromium molybdenum steel, H Cr13 series stainless steel, K malleable cast iron, L aluminum alloy, P 0Cr18Ni9 series stainless steel, PL 00Cr19Ni10 series stainless steel, Q ductile iron, R 0Cr12Ni12Mo kila kuhiliʻole, RL 00Cr17Ni14Mo2 moʻo Kuhili ʻole, S plastic, T keleawe a me ke keleawe huila, Ti titanium a me titanium alloy, V chromium molybdenum vanadium kila, Z hina hina hao.
