ʻO Valve Sealing kahi'āpana koʻikoʻi o ka valve holoʻokoʻa,ʻo ia ke kumu nui e pale ai i ka leakage,ka'ōpūUa kapaʻiaʻo Sealing Sealing i ke kaniʻana o ke kaniʻana,ʻo ia kahi hui e hoʻopili pololei ai me keʻano o ka paila i ke kaheʻana mai. Ke hoʻohanaʻia ka palahala, aia nā'āpana likeʻole i ka paila, e like me nā'āpana likeʻole, a me nā koho o nāʻano'ē aʻe.
TwaysValvehoʻomanaʻo iāʻoe e hoʻokaʻawaleʻia nā mea kūʻai aku i nā koho balota maʻelua mau'āpanaʻelua ʻO nā kohoʻoleʻole e hoʻohanaʻia ma nā kīwaha pila i nā mahana maʻamau a me ka paʻakikī,ʻoiai ke kauʻana i nā noi he nui. ikaika kiʻekiʻe.
ʻOi aku ka maikaʻi o Synthetic ma mua o ka'ōpala kūlohelohe ma nā'ōlelo o ka coristanceʻaila ʻO ka maʻamau,ʻo keʻano o ka hanaʻana o ka stonthetic rubber he t≤150°C, ka cubber kūlohelohe t≤60°C, a hoʻohanaʻiaʻo Rubber no ka hōʻailonaʻana o nā Vlobe Blobe Blobe, Gate Volves, nā Vityfly Colleves PNN≤1mpa.
2. Nylon
ʻO Nylon nā hiʻohiʻona o nā'āpana liʻiliʻi o ka liʻiliʻi a me ke kū'ēʻana o ka corrosion. Ua hoʻohana nuiʻiaʻo Nylon no nā kumu balota a me nā vale uila me ka wela me ka mahana t≤90°C a me ke kumu nominal stick pn≤32Mpa.
Ua hoʻohana nuiʻiaʻo PTF no nā Vlobe Valbe, Gate Valves, Boot Valves, Etc. Me kahi mahana t≤232°C a me kahi kumu koho bayhil pn≤6.4mpa.

Ua hoʻohanaʻia ka hao hao no nā hale kūʻai o Gate, Globe Vlives, Plug Vilves, Etc. No ka mahana t≤100°C, nominal still pn≤1.6mppa, hau a me ka aila.
5. BIBBITT ALLOY
Hoʻohanaʻiaʻo Bobbit Acloy no ka VIGH Globe Blobe Blobe me ka mahana T-70 ~ 150℃a me ke kumu nominal mn≤2.5MPA.
6. Copper alloy
Nā mea hoʻohana maʻamau no nā mea kūʻai aku i nā koho back he 6-6-3 tin bronze a me 58-2-2 mangeanese. He lole maikaʻiʻo Copper i ka paleʻana a kūpono hoʻi no ka wai a me ka heleʻana me ka mahana me ka wela t≤200℃a me ke kumu nominal mn≤1.6MPA. Hoʻohana pinepineʻia ia i loko o nā hale o nā hale kūʻai

ʻO nā helu maʻamau maʻamau o ka chromium stielless stielless he 2c13 a me 3cr13, ua hoʻohuliʻia a me kaʻoluʻolu. Hoʻohana pinepineʻia ia ma nā awāwa o ka wai, steam a me ka steam a me ka petroulaum me ke wela t≤450℃a me ke kumu nominal mn≤32Mpa.
8.ʻO Chrome-nickel-nickel-titenium stielless steel
ʻO ka papa inoa maʻamau o ka chromium-Nickel-Nickel-Titenium Stalinless Steel he 1Cr18ni9ti He kūpono ia no ka Steam a me nā Media'ē aʻe me kahi mahana t≤600°C a me kahi kumu koho bayhil pn≤6.4mpa, a hoʻohanaʻia no nā huapalapala uila, nā pōpō ball, etc.
9.ʻO ka kila kila
ʻO ka papa maʻamau i hoʻohanaʻia ma ka Nitriding Steel he 38crmola Hoʻohana pinepineʻia ia i loko o nā hale o nā hale o nā hale noho me ka mahana t≤540℃a me ke kumu nominal mn≤10mpa.
10. Ke luku nei
Hoʻopili i nā kaʻina hana pololei i ka papa hōʻailona mai nā mea o ke kino a iʻole ke kino, a laila hana i keʻano o ka mālamaʻana i ka mālamaʻana. ʻO kaʻaoʻao o ka hōʻailona he mea maikaʻi loa i ke kū'ē. No ka mana o ke kikowaena kikowaena blowdown.
Ke hoʻohanaʻia ka Valve, nā mea e pono e nānāʻia e like me kēia:
1. E ho'āʻoʻia ka hana o ka Valve e hōʻoia e hōʻoia i kāna hana.
2. E nānā inā he paleʻia keʻano o ka valve o ka vanve, a hoʻoponopono a hoʻololi paha e like me ke kūlana.
