ʻO ka pahu pahu, kahi pahu e hoʻohana ana i kahi kino plug me kahi puka ma ke ʻano he lālā wehe a pani. Hoʻololi ke kino plug me ke koʻokoʻo valve no ka hoʻokō ʻana i ka hana wehe a pani ʻia, ʻo kahi pahu pahu liʻiliʻi me ka ʻole o ka paʻi ʻana i ʻike ʻia he "cock". ʻO ke kino plug o ka valve plug he kino conical (ʻike ʻia ʻo ia he cylinder), e hui pū ana me ka ʻili o ka lua conical o ke kino valve e hana i kahi paʻa. ʻO ka valve plug ke ʻano mua loa o ka valve i hoʻohana ʻia, me ke ʻano maʻalahi, ka wehe wikiwiki a me ka pani ʻana, a me ka haʻahaʻa haʻahaʻa o ka wai. , kiʻekiʻe wehe a pani ikaika, a maʻalahi lole. Hoʻohana wale ʻia lākou ma nā noi haʻahaʻa (ʻaʻole kiʻekiʻe ma mua o 1 MPa) a me ke anawaena liʻiliʻi (emi ma lalo o 100 mm). I mea e hoʻonui ai i ka hoʻohana ʻana o nā kīwaha plug, ua kūkulu ʻia nā hale hou he nui. ʻO ka valve plug oil lubricated ka mea nui loa. Hoʻokomo ʻia ka ʻaila lubricating kūikawā mai ka piko o ke kino plug ma waena o ka lua tapered o ke kino valve a me ke kino plug e hana i kahi kiʻi ʻaila e hōʻemi ai i ka wehe ʻana a me ka pani ʻana o ka torque, hoʻomaikaʻi i ka hana sila a me ke ola lawelawe. Hiki i kāna kaomi hana ke piʻi i 64 MPa, hiki ke piʻi ka mahana hana kiʻekiʻe i 325 ℃, a hiki i ke anawaena kiʻekiʻe ke hiki i 600 mm. Loaʻa nā ʻano ala like ʻole no nā kiwi plug. Hoʻohana nui ʻia ke ʻano pololei maʻamau e ʻoki i ka wai. He kūpono nā ʻāpana ʻekolu ala a me nā ala ʻehā no nā kiwi hoʻohuli wai. ʻO ka lālā wehe a pani ʻana o ka valve plug he cylinder perforated e huli ana e pili ana i kahi axis perpendicular i ke kahawai, a laila e loaʻa ai ke kumu o ka wehe a pani ʻana i ke kahawai. Hoʻohana nui ʻia nā valve plug no ka wehe a pani ʻana i nā pipeline a me nā mea paahana.
ʻO nā pōmaikaʻi nui o nā valve plug penei:
1. He kūpono no ka hana pinepine, ka wehe wikiwiki a me ka māmā.
2. Haʻahaʻa wai kū'ē.
3. ʻO ka hana maʻalahi, ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, a me ka mālama maʻalahi.
4. Hana maikaʻi ke sila.
5. Hiki ke hoʻokaʻawale ʻia ke ala kahe o ka mea waena, me ka nānā ʻole i ke kuhikuhi hoʻonohonoho.
6. ʻAʻohe haʻalulu, haʻahaʻa haʻahaʻa.
7. Hiki ke hoʻokaʻawale ʻia nā kiwi hoʻopaʻa i ʻehā ʻano e like me ko lākou ʻano: nā puʻupuʻu hoʻopaʻa paʻa paʻa, nā puʻupuʻu hoʻopaʻa paʻa ponoʻī, nā puʻupuʻu puʻupuʻu paʻi, a me nā kiwi hoʻoheheʻe ʻaila. E like me ke ʻano o ke kanal, hiki ke hoʻokaʻawale ʻia i ʻekolu ʻano: pololei ma ke ʻano, ʻekolu ala ʻano, a me ke ʻano ʻehā.
