ʻO nā ʻauwaʻa Pepa ʻOihana Nui
ʻO kēia ʻano valve butterfly ka maʻamau a puni no nā noi hana maʻamau. Hiki iā ʻoe ke hoʻohana ia mau mea no nā noi e pili ana i ka ea, ka mahu, ka wai a me nā wai a me nā kinoea ʻē aʻe. Wehe a pani nā kiwi lele lele lawelawe maʻamau me kahi lima kūlana 10. Hiki iā ʻoe ke hoʻokaʻawale i kā lākou wehe a pani ʻana me ka hoʻohana ʻana i ka ea a i ʻole ka mea hoʻokele uila no ka hoʻopaʻa ʻana a me ka hoʻokaʻawale ʻana.
Uhi ka noho o ka valve i ke kino no ka hōʻoia ʻana ʻaʻole pili nā mea i hana ʻia me ke kino. He kūpono kēia hoʻolālā noho no ka hana ʻana i nā noi vacuum. Holo ke kumu o ka valve i loko o ka diski a hoʻopili ʻia i ka disc ma o ka spline paʻa, me 3 bushings ma luna a ma lalo e hana ma ke ʻano he kumu.
ʻO kekahi o nā pōmaikaʻi o nā kīwaha butterfly lawelawe maʻamau ʻo ia ka maʻalahi o kā lākou hoʻolālā ʻana, e ʻae iā lākou e hana maʻamau e kūpono me nā noi kaʻina hana paipu. Hoʻohui ʻia, hoʻopaʻa ʻia lākou me ka hoʻohana ʻana i nā ʻano elastomer like ʻole, a hiki iā ʻoe ke koho i kahi ʻano elastomer i kūpono i kāu kālā. ʻO ka ʻaoʻao haʻahaʻa o kēia mau valve ʻo ia ke kiʻekiʻe-torque a ʻaʻole hiki i ka mea noho ke hoʻomanawanui i nā mahana kiʻekiʻe a me nā pae kiʻekiʻe ma mua o 285 PSI. ʻAʻole hiki ke hoʻohana ʻia i nā noi nui aʻe, no ka mea, ʻike pinepine ʻia lākou i nā nui a hiki i 30 in.
ʻO nā kiʻi paʻi kiʻekiʻe
Hiki i nā kiwi lele lele hana kiʻekiʻe ke lawelawe i nā mea a pau i hiki i nā kiwi lele lele lawelawe maʻamau ke hana, akā ua hana ʻia lākou e pale aku i nā wai a me nā kinoea hiki ʻole i nā kiwi lawelawe maʻamau ke ʻae. Hana ʻia lākou me nā noho PTFE e hiki ke mālama i nā wai hoʻoheheʻe kemika a me ka corrosive, nā kinoea a me ka mahu. ʻOiai ke kūkulu ʻia nei nā kīwaha butterfly maʻamau me nā elastomers hiki ke hoʻopau ʻia, hoʻohana ʻia nā kiwi lele lele kiʻekiʻe e like me ka graphite e sila ai i ka noho. ʻO ka hoʻohui ʻē aʻe, hiki mai lākou i ka nui a hiki i ka 60 i hiki ke hoʻohana ʻia no nā noi nui.
ʻAʻohe ʻano o nā mea ʻino āu e hana nei, hiki iā ʻoe ke loaʻa i kahi valve butterfly hana kiʻekiʻe e hoʻokō i kāu mau pono. Inā pilikia kāu noi no nā hoʻokuʻu mahuka, hiki iā ʻoe ke hoʻohana i ka valve butterfly hana kiʻekiʻe e hōʻike ana i nā hoʻonui sila ʻana no ka hoʻomalu ʻana i ka leak-proof. Inā hana kāu paipu i nā mahana anu loa, hiki iā ʻoe ke loaʻa i nā kiwikā lele lele hana kiʻekiʻe me nā hoʻonui ʻāʻī i kaomi ʻia e hiki ai ke hoʻokaʻawale i ka paipu.
Hiki iā ʻoe ke loaʻa nā kiwi lele lele hana kiʻekiʻe i hana ʻia me ke kila kalapona, ke kila kila, a me nā metala ʻē aʻe. Hoʻopili ʻia nā metala i hiki i ka valve ke kū i nā mahana haʻahaʻa e like me ka -320 degere F a me ke kiʻekiʻe e like me 1200 degere F, a hoʻomanawanui i nā pae kaomi a hiki i 1440 PSI. ʻO ka hapa nui o nā kiwi pepeke hana kiʻekiʻe he paʻa i loko o ke kino e pale aku ai i ka hele nui ʻana, a me kahi puʻupuʻu hiki ke hoʻololi ʻia e pale i ka leaka o waho.
