ʻO ka hoʻopaʻa ʻana i ka valve he ʻāpana koʻikoʻi o ka valve holoʻokoʻa, ʻo kāna kumu nui ka pale ʻana i ka leakage,ka pahu hopukapa ʻia ka noho sealing ring sealing ring, he hui ia e pili pono ana me ka medium i ka pipeline a pale i ke kahe ʻana o ka medium. Ke hoʻohana ʻia ka valve, aia nā ʻano media like ʻole i ka pipeline, e like me ka wai, gas, ʻaila, corrosive media, a me nā mea ʻē aʻe, a hoʻohana ʻia nā sila o nā valve like ʻole ma nā wahi like ʻole a hiki ke hoʻololi i nā ʻano like ʻole.
TWSValvehoʻomanaʻo iā ʻoe e hiki ke hoʻokaʻawale ʻia nā mea o nā sila valve i ʻelua mau ʻāpana, ʻo ia nā mea metala a me nā mea metala ʻole. Hoʻohana maʻamau ʻia nā sila non-metal i nā pipeline i ka mahana maʻamau a me ke kaomi, ʻoiai ʻo nā sila metala ka nui o nā noi a hiki ke hoʻohana ʻia i nā wela kiʻekiʻe. kaomi kiʻekiʻe.
ʻOi aku ka maikaʻi o ka lāʻau synthetic ma mua o ka lāʻau kūlohelohe ma ke ʻano o ka pale ʻana i ka aila, ka pale wela a me ke kūpaʻa corrosion. ʻO ka mea maʻamau, ʻo ka wela hana o ka lāʻau synthetic he t≤150°C, ʻo ka lāʻau maoli ka t≤60°C, a hoʻohana ʻia ka lāʻau lapaʻau no ka hoʻopaʻa ʻana i nā kīwaha honua, nā kīwaha puka, nā kīwaha diaphragm, nā kīwaha butterfly, nā kiwi hoʻopaʻa, nā kiwi a me nā kiwi ʻē aʻe me ke kaomi inoa PN≤1MPa.
2. Nailona
Loaʻa i ka Nylon nā hiʻohiʻona o ka liʻiliʻi friction coefficient a me ka pale corrosion maikaʻi. Hoʻohana nui ʻia ʻo Nylon no nā kiwi kinipōpō a me nā kiwi honua me ka wela t≤90°C a me ke kaomi inoa PN≤32MPa.
PTFE ka hapanui hoʻohana 'ia no ka honua kiwikā, puka kiwipa, poepoe kiwikā, etc. me ka wela t≤232°C a me kahi kaomi inoa PN≤6.4MPa.
4. Ka hao hao
Hoʻohana ʻia ka hao no nā ʻīpuka ʻīpuka, nā kiwi honua, nā kiwi hoʻopili, a me nā mea ʻē aʻe no ka wela t≤100°C, kaomi inoa PN≤1.6MPa, kinoea a me ka aila.
5. ʻO ka huila Babbitt
Hoʻohana ʻia ʻo Babbitt alloy no ka pahu ammonia honua me ka mahana t-70 ~ 150℃a me ke kaomi inoa PN≤2.5MPa.
6. Aleki keleawe
ʻO nā mea maʻamau i hoʻohana ʻia no nā hui keleawe he 6-6-3 tin keleawe a me 58-2-2 keleawe manganese. He maikaʻi ke kapa komo keleawe a kūpono i ka wai a me ka mahu me ka wela t≤200℃a me ke kaomi inoa PN≤1.6MPa. Hoʻohana pinepine ʻia i loko o nā ʻīpuka puka, nā kīwaha honua, nā kīwaha nānā, nā kīwaha plug, etc.
7. Ke kila kila kila
ʻO nā māka maʻamau o ka chromium stainless steel ʻo 2Cr13 a me 3Cr13, i hoʻopiʻi ʻia a hoʻopaʻa ʻia, a loaʻa ke kūpaʻa maikaʻi. Hoʻohana pinepine ʻia ma nā kiwi wai, ka mahu a me ka ʻaila me ka wela t≤450℃a me ke kaomi inoa PN≤32MPa.
8. Chrome-nickel-titanium kila kila
ʻO ka papa hana maʻamau o ka chromium-nickel-titanium stainless steel ʻo 1Cr18Ni9ti, he maikaʻi ke kūpaʻa corrosion, erosion a me ka wela. He kūpono ia no ka mahu a me nā mea ʻē aʻe me ka wela t≤600°C a me kahi kaomi inoa PN≤6.4MPa, a ua hoʻohana ʻia no nā kīwaha honua, nā ʻāpana pōpō, etc.
9. Ke kila Nitriding
ʻO ka papa hana maʻamau o ke kila nitriding ʻo 38CrMoAlA, nona ke kūpaʻa corrosion maikaʻi a me ka pale ʻana ma hope o ka mālama ʻana i ka carburizing. Hoʻohana pinepine ia i nā ʻīpuka puka mana me ka wela t≤540℃a me ke kaomi inoa PN≤10MPa.
10. Boronizing
Hoʻoponopono pololei ʻo Boronizing i ka ili hoʻopaʻa ʻana mai ka mea o ke kino valve a i ʻole kino disc, a laila hana i ka mālama ʻana i ka ʻili o ka boronizing. ʻO ka ʻili hoʻopaʻa ʻana he kūʻē maikaʻi. No ka pahu hoʻokuʻu ʻana i ke kahua mana.
Ke hoʻohana ʻia ka valve, ʻo nā mea e pono e nānā ʻia penei:
1. Pono e ho'āʻoʻia ka hana sealing o ka valve e hōʻoia i kāna hana.
2. E nānā inā pa'a ka ili o ka valve, a ho'oponopono a ho'ololi paha e like me ke kūlana.
