ʻO kēia ʻano ʻōleʻa pōleʻa no ka pahu pōpō paʻa a he noho hoʻokahi hoʻi e hoʻopaʻa ai i ka pōleʻa pōleʻa.ʻO ka hana hoʻoponopono ka mea maikaʻi loa i loko o ka pahu pōpō, ʻo ke ʻano kahe ka pākēneka like, a ʻo ka ratio hiki ke hiki i 100:1.ʻO kona ʻāpana ʻano V he hana ʻako me ka noho metala, kūpono loa no ka media i loaʻa i nā fibers, nā ʻāpana paʻa liʻiliʻi, slurry.
He 90 degere ka hoʻololi like ʻana o ka pahu kinipōpō, koe wale nō ʻo ke kino plug he pōʻai me ka pōʻai i loko o ka lua a i ʻole ke ala i kona axis.Hoʻohana nui ʻia ka valve ball i ka pipeline e ʻoki, puʻunaue a hoʻololi i ke ala kahe o ka waena.Pono e hoʻohuli ʻia i 90 degere a hiki ke pani paʻa ʻia ka torque.ʻOi aku ka maikaʻi o nā kiwi kinipōpō no ka hoʻohana ʻana e like me nā kiwi hoʻololi a pani ʻia, akā ua hoʻolālā nā hana hou i nā kiwi pōlele e hāʻawi i ka throttling a me ka hoʻokele kahe ʻana, e like me nā valve V-ball.

He kūpono no ka hana pinepine, wehe koke a pani ʻana, paona māmā, kūpaʻa wai liʻiliʻi, ʻano maʻalahi, liʻiliʻi liʻiliʻi liʻiliʻi, paona māmā, mālama maʻalahi, hana hoʻopaʻa sila maikaʻi, ʻaʻole i kaupalena ʻia e ke kuhikuhi hoʻonohonoho, hiki ke hoʻokaʻawale ʻia ke ala kahe o ka medium. , ʻaʻohe haʻalulu, walaʻau haʻahaʻa .
1. ʻO ke kino monolithic o ke kino kīpē: ʻO ke kino kīpē o ke ʻano clamp a me ka flange type V-type ball valve he mea hoʻohui pū ʻia i ka ʻaoʻao, nona ka rigidity structural ikaika a ʻaʻole maʻalahi ke kumu o ka deformation a me ka leakage.
2. ʻO luna a me lalo iho-lubricating bearings: Ua hoʻolakoʻia ke kino valve me nā bearings lubricating pono'ī o luna a me lalo, kahi nui o ka pilina me ka pahu valve, ka mana nui a me ka liʻiliʻi liʻiliʻi liʻiliʻi, e ho'ēmi ana i ka torque o ka valve.
3, hiki ke koho ʻia ka noho valve e like me nā pono o ke ʻano a me nā kūlana hana, metala paʻakikī a i ʻole PTFE sila palupalu: metala paʻa paʻa paʻa noho sila e hoʻopaʻa ai i ka ʻili paʻa paʻa, spherical hard chrome a i ʻole spray welding, ion nitriding a me nā lāʻau paʻakikī ʻē aʻe. , Hoʻonuiʻia ke ola lawelawe o kaʻili o ka sila a hoʻonuiʻia ka pale wela;ʻO ka noho ʻana o ka valve PTFE sealing palupalu a i ʻole ka noho ʻana o ka valve PTFE i hoʻoikaika ʻia he hana hoʻopaʻa maikaʻi a me ka pale ʻana i ka corrosion, a he ākea ākea.
4. Maikaʻi a me ka hana pono: He māmā ke kaumaha o ke kino valve, he liʻiliʻi ke kumu o ka valve stem torque, a he liʻiliʻi nā kikoʻī e pili ana i ka pneumatic a i ʻole nā mea hoʻokele uila, ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻia me nā ʻano ʻano ʻē aʻe o nā valve hoʻoponopono.
5, hoʻololi ka medium i kahi ākea ākea: ma muli o ka ikaika o ka shear ma waena o ka wehe ʻana o ka V-like a me ka noho valve, a me ke ala maʻemaʻe a me ka pōʻai o ka lua valve, ʻaʻole maʻalahi ka mea e hōʻiliʻili i loko o ka lua o loko, no laila ua kūpono ia no ka wai wai, kūpono no ka mana ʻōnaehana me ka fiber a me ka media particle solid.

5, sealing a me ka ikaika ho'āʻo kūlana
ʻO ka maʻamau ho'āʻo ikaika a me ka sila: GB / T 4213-2007
Ka pae sila paʻakikī: Inā ʻaʻohe koi kūikawā o ka mea hoʻohana, hoʻohana ʻia ka maʻamau papaʻaina.Ke noi ka mea hoʻohana iā ia, hiki ke hoʻokō ʻia e like me GB/T 4213-2007?V pae maʻamau.ʻO ke kaomi hoʻāʻo ikaika he 1.5 mau manawa o ke kaomi nominal.Hoʻokō ʻia ka hoʻāʻo ʻana o ka sila ma ka packing a me ka flange ma ke kaomi o 1.1 mau manawa o ka kaomi nominal.Hoʻāʻo ʻia ka sila noho e like me ka ʻokoʻa ʻoi loa.Inā ʻaʻole maopopo ka ʻokoʻa kiʻekiʻe o ke kaomi, e kaomi i ka 1.0MPa (ke kaomi wai) i ka hoʻāʻo, i ka wā i emi ai ka ʻokoʻa kiʻekiʻe ma mua o 0.6MPa, lawe ʻia ka hoʻāʻo ma ke kaomi o 0.6MPa, a ua hoʻāʻo ʻia ke ʻano me ka wai me ka corrosion. a me ka mea pale unahi.
