ʻO ka hoʻopaʻa paʻa ʻana o ka valve butterfly e pili ana i nā ʻaoʻao ʻelua o ka hui hoʻopaʻa ʻana i hana ʻia me nā mea metala a i ʻole nā mea paʻakikī ʻē aʻe.ʻAʻole maikaʻi ka hana hoʻopaʻa ʻana o kēia ʻano sila, akā he kiʻekiʻe ke kūpaʻa wela, ke kūpaʻa a me ka hana mechanical maikaʻi.Eia kekahi laʻana: kila + kila;Ke kila + keleawe;Steel+graphite;ʻO ke kila + kila kila.ʻO ke kila ma ʻaneʻi paha he hao hao, kila hoʻoheheʻe ʻia, ke kila kila a i ʻole ke kila no ka hoʻoheheʻe ʻana a me ka hoʻohu ʻana.
ʻO ka pahu lele lele sila palupalu
ʻO ke sila palupalu o ka valve butterflye pili ana i kekahi ʻaoʻao o ka hui hoʻopaʻa ʻana i hana ʻia i nā mea metala, a ʻo kekahi ʻaoʻao i hana ʻia me nā mea elastic non-metallic.He maikaʻi ka hana hoʻopaʻa ʻana o kēia ʻano sila, akā ʻaʻole kūpaʻa i ka wela kiʻekiʻe, maʻalahi ke ʻaʻahu, a me ka hana mechanical maikaʻi ʻole, e like me: steel + rubber;Steel+PTFE, etc.
Hana ʻia ka noho sila palupalu i nā mea metala ʻole me kekahi ikaika, paʻakikī a me ka pale wela.Me ka hana maikaʻi, hiki iā ia ke hoʻokō i ka leakage zero, akā maikaʻi ʻole kona ola lawelawe a me ka hoʻololi ʻana i ka mahana.Hana ʻia ke sila paʻa i ka metala, a ʻoi aku ka maikaʻi o ka hana sealing.ʻOiai ke ʻōlelo nei kekahi mau mea hana e hiki ke hoʻokō ʻia ka leakage zero.ʻAʻole hiki i ka sila palupalu ke hoʻokō i nā koi kaʻina no kekahi mau mea corrosive.Hiki i ke sila paʻakikī ke hoʻoponopono i ka pilikia, a hiki i kēia mau sila ʻelua ke hoʻokō kekahi i kekahi.E pili ana i ka hana hoʻopaʻa ʻana, ʻoi aku ka maikaʻi o ka sealing palupalu, akā i kēia manawa hiki ke hoʻokō ʻia ka hana sealing o ka sila paʻa i nā koi kūpono.ʻO nā mea maikaʻi o ka sila palupalu he hana hoʻopaʻa maikaʻi, ʻoiai ʻo nā hemahema he maʻalahi ka wā kahiko, ʻaʻahu a me ke ola lawelawe pōkole.He lōʻihi ke ola lawelawe ʻana o ka sila paʻa, akā ʻoi aku ka maikaʻi o kāna hana sila ʻana ma mua o ka sila palupalu.
ʻO ka nui o nā ʻokoʻa hoʻolālā penei:
1. Nā ʻokoʻa o ka hale
ʻO nā kiwi lele lele sila palupaluʻO ka hapa nui o nā ʻano laina waena, ʻoiai ʻo nā kiwikā pepeke sila paʻakikī ka hapa nui o nā ʻano eccentric hoʻokahi, ʻelua eccentric a me triple eccentric.
2. Kū'ē wela
Hoʻohana ʻia ke sila palupalu ma ke ʻano wela maʻamau.Hiki ke hoʻohana i ka sila paʻa i ka wela haʻahaʻa, ka mahana maʻamau, ka wela kiʻekiʻe a me nā wahi ʻē aʻe.
3. Pumi
Hoʻopili haʻahaʻa haʻahaʻa haʻahaʻa - ke kaomi maʻamau, hiki ke hoʻohana ʻia ke sila paʻakikī i nā kūlana hana e like me ka medium a me ke kiʻekiʻe.
4. Hoʻokō sila
ʻOi aku ka maikaʻi o ka hana hoʻopaʻa ʻana o ka valve sealing butterfly valve a me ka tri eccentric hard sealing butterfly valve.Hiki i ka tri eccentric butterfly valve ke mālama i ka sila maikaʻi ma lalo o ke kaomi kiʻekiʻe a me ke kaiapuni wela.
Ma ka nana aku o na ano maluna, uapāpaʻi pulupulu hoʻopaʻa palupaluHe kūpono ia no ka wehe ʻana a me ka pani ʻana a me ka hoʻoponopono ʻana i nā pipelines ventilation a me ka wehe ʻana o ka lepo, ka mālama wai, ka ʻoihana māmā, ka ʻaila, ka ʻoihana kemika a me nā ʻoihana ʻē aʻe.Hoʻohana nui ʻia ka valve butterfly sealing paʻakikī no ka hoʻomehana ʻana, ka lako kinoea, ke kinoea, ka aila, ka waikawa a me ke kaiapuni alkali.
Me ka hoʻohana nui ʻana o ka valve butterfly, ʻo kāna mau hiʻohiʻona o ka hoʻonohonoho maʻalahi, ka mālama maʻalahi a me ke ʻano maʻalahi e ʻike hou aʻe.ʻO nā kiwi lele lele sila palupalu uila, Pneumatic soft seal butterfly valves, hard seal butterfly valves, etc. e ho'omaka ana e pani i ka uwila puka makani, globe valves, etc.
