He ʻāpana koʻikoʻi ka mea sila valve o ke sila valve. He aha nā mea sila valve? Ua ʻike mākou ua māhele ʻia nā mea apo sila valve i ʻelua mau ʻāpana: metala a me ka mea ʻole metala. Eia kahi hoʻolauna pōkole i nā kūlana hoʻohana o nā mea sila like ʻole, a me nā ʻano valve i hoʻohana pinepine ʻia.
1. Laho hana
ʻOi aku ka maikaʻi o nā waiwai piha o ka laholio synthetic e like me ke kūpaʻa ʻaila, ke kūpaʻa wela a me ke kūpaʻa ʻana i ka pala ma mua o ka laholio kūlohelohe. Ma keʻano laulā, ʻo ka mahana hoʻohana o ka laholio synthetic he t≤150 ℃, a ʻo ka mahana o ka laholio kūlohelohe he t≤60 ℃. Hoʻohana ʻia ka laholio e sila i nā kiwikā honua.kiwikā puka noho laholio, nā kiwikā diaphragm,rkiwikā pulelehua noho ubber, rkiwikā nānā hoʻololi noho ubber (nā kiwikā nānā), nā kiwikā ʻūmiʻi a me nā kiwikā ʻē aʻe me ke kaomi maʻamau PN≤1MPa.
2. Nailoni
Loaʻa i ka Nylon nā ʻano o ke koina friction liʻiliʻi a me ke kūpaʻa maikaʻi i ka corrosion. Hoʻohana nui ʻia ka Nylon no nā kiwikā pōpō a me nā kiwikā globe me ka mahana t≤90℃ a me ke kaomi inoa PN≤32MPa.
3. PTFE
Hoʻohana nui ʻia ka PTFE no nā kiwikā honua,nā kiwikā puka, nā kiwikā pōpō, a pēlā aku me ka mahana t≤232℃ a me ke kaomi inoa PN≤6.4MPa.
4. Hao hao
Hoʻohana ʻia ka hao i hoʻolei ʻia nokiwikā puka, kiwikā honua, kiwikā plug, a pēlā aku no ka mahana t≤100℃, kaomi inoa PN≤1.6MPa, kinoea a me ka ʻaila.
5. ʻO ke kinikini Babbitt
Hoʻohana ʻia ka hui ʻana o Babbitt no ka valve honua ammonia me ka mahana t-70 ~ 150 ℃ a me ke kaomi inoa PN≤2.5MPa.
6. Mea hoʻohuihui keleawe
ʻO nā mea maʻamau no nā mea hoʻohuihui keleawe he 6-6-3 tin bronze a me 58-2-2 manganese brass. Loaʻa i ke keleawe ke kūpaʻa maikaʻi i ka ʻaʻahu a kūpono no ka wai a me ka mahu me ka mahana t≤200℃ a me ke kaomi maʻamau PN≤1.6MPa. Hoʻohana pinepine ʻia ia i lokonā kiwikā puka, nā kiwikā poepoe,nā kiwikā nānā, nā kiwikā plug, a pēlā aku.
7. Ke kila kila ʻole Chrome
ʻO nā papa maʻamau o ke kila kila chromium ʻo 2Cr13 a me 3Cr13, i hoʻopau ʻia a hoʻomaʻamaʻa ʻia, a he kūpaʻa maikaʻi ko lākou i ka pala. Hoʻohana pinepine ʻia ia i nā kiwikā no nā mea hana e like me ka wai, ka mahu a me ka ʻaila me ka mahana t≤450℃ a me ke kaomi maʻamau PN≤32MPa.
8. Ke kila kila chromium-nickel-titanium
ʻO ke ʻano maʻamau o ke kila kila chromium-nickel-titanium ʻo 1Cr18Ni9ti, nona ke kūpaʻa maikaʻi i ka pala, ka pale ʻana i ka ʻino a me ke kūpaʻa wela. He kūpono ia no ka mahu, ka waikawa nitric a me nā mea hana ʻē aʻe me ka mahana t≤600℃ a me ke kaomi maʻamau PN≤6.4MPa, hoʻohana ʻia no ka valve honua, valve pōpō, a pēlā aku.
9. Ke kila nitrided
ʻO ke ʻano maʻamau o ke kila nitrided ʻo 38CrMoAlA, nona ke kūpaʻa maikaʻi i ka palaho a me ke kūʻē ʻana i nā ʻōpala ma hope o ka mālama ʻana i ka carburizing. Hoʻohana pinepine ʻia i ka valve puka o ke kahua mana me ka mahana t≤540℃ a me ke kaomi inoa PN≤10MPa.
10. Hoʻopōʻino ʻana
Hoʻoponopono pololei ka Boronizing i ka ʻili sila mai ka mea o ke kino valve a i ʻole ke kino disc, a laila hana i ka mālama ʻana i ka ʻili boronizing, he kūpaʻa maikaʻi ka ʻili sila. Hoʻohana ʻia i loko o ka valve blowdown kikowaena mana.
