ʻO kēia ʻano kīpē pōleʻa pili i ka pahu pōlele paʻa a ʻo ia hoʻi kahi noho hoʻokahi sealing ball valve.ʻO ka hana hoʻoponopono ʻoi aku ka maikaʻi loa i 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 nā fibers, nā ʻāpana paʻa liʻiliʻi, slurry.

He 90 degere like ka hoʻololi ʻana o ka pahu kinipōpō, koe wale nō ʻo ke kino plug he pōʻai me ka pōʻai ma loko o ka lua a i ʻole ke ala i kona axis.Hoʻohana nui ʻia ka valve ball i ka pipeline e ʻoki, e puʻunaue a hoʻololi i ke ala kahe o ka waena.Pono wale ia e hoʻohuli ʻia i 90 degere a hiki ke pani paʻa i ka torque.ʻOi aku ka maikaʻi o ka hoʻohana ʻana i nā kiwi pōkā no ka hoʻohana ʻana e like me nā kiwi hoʻololi a pani ʻia, akā ua hoʻolālā nā hana hou i nā kiwi pōpō e hāʻawi i ka throttling a me ka hoʻokele kahe ʻana, e like me nā valve V-ball.

Nā hiʻohiʻona

He kūpono no ka hana pinepine, wehe wikiwiki a pani ʻana, paona māmā, pale 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, haʻahaʻa leo .

1. ʻO ke kino monolithic o ke kino kīpē: ʻO ke kino kīpē o ke ʻano clamp a me ke ʻano flange V-type ball valve he ʻano hui 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 paʻa paʻa a i ʻole PTFE sila palupalu: metala paʻa paʻa paʻa noho sila e hoʻopaʻa ʻia i ka ʻili paʻa paʻa, spherical hard chrome a i ʻole spray welding, ion nitriding a me nā lāʻau paʻakikī ʻē aʻe. , Hoʻonuiʻia ka 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 maikaʻi ke hoʻopaʻa ʻana 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 uila uila, ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻana me nā ʻano ʻē aʻe o nā valve hoʻoponopono.

5, hoʻololi ka mea waena 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 ka maʻalahi a me ka pōʻai o ke ala kahe 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 mālama ʻana i ka ʻōnaehana me ka fiber a me ka media particle solid.
