Sila paʻa paʻa lele
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 pāpaʻi lepe 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 kūʻē i ka wela kiʻekiʻe, maʻalahi ke ʻaʻahu, a he maikaʻi ʻole ka hana mechanical, 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 hoʻopaʻa ʻana i ka sila, akā i kēia manawa hiki ke hoʻokō i nā koi kūpono. ʻO nā mea maikaʻi o ka sila palupalu he hana hoʻopaʻa maikaʻi, ʻoiai ʻo nā hemahema ka maʻalahi o ka ʻelemakule, ʻaʻahu a me ke ola lawelawe pōkole. He lōʻihi ke ola lawelawe ʻana o ka sila paʻa, akā ʻoi aku ka ʻino o kāna hana sila ʻana ma mua o ka sila palupalu.
ʻO ka nui o nā ʻokoʻa hoʻolālā penei:
1. Nā ʻokoʻa hoʻolālā
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 ana i na ano maluna, uapāpaʻi pulupulu hoʻopaʻa palupaluhe kūpono no ka wehe ʻana a me ka pani ʻana a me ka hoʻoponopono ʻana i nā pipelines ventilation a me ka hoʻohemo ʻana i 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 kona 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.
