Hoʻohana ʻia ka valve e wehe a pani i ka pipeline, e hoʻomalu i ke ala kahe, hoʻoponopono a hoʻopaʻa i nā ʻāpana o ka mīkini hoʻouna (ka wela, kaomi a me ke kahe) nā mea hoʻopili pipeline. E like me kāna hana, hiki ke hoʻokaʻawale ʻia i ka valve shutoff, check valve, regulatoring valve, etc.

ʻO ka valve ka ʻāpana hoʻomalu i ka ʻōnaehana lawe wai, nona nā hana o ka ʻoki ʻana, ka hoʻoponopono, ka hoʻohuli ʻana, ka pale ʻana i ka countercurrent, ka hoʻomau ʻana i ke kaomi, diversion a overflow relief, etc.

Hiki ke hoʻohana ʻia nā pāpaʻi e hoʻomalu i ke kahe ʻana o ka ea, ka wai, ka mahu, nā mea hoʻoheheʻe ʻia, ka lepo, ka ʻaila, ka metala wai a me nā ʻano radioactive a me nā ʻano wai ʻē aʻe. Hoʻokaʻawale ʻia nā kiwi e like me ka mea i hoʻolei ʻia i nā kiwi hao, nā kiwi kila, nā kiwi kila (201, 304, 316, a me nā mea ʻē aʻe), chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, pālua-phase steel valves, plastic valves, non-standard custom valves.

Aia ʻo Valve i loko o ka ʻōnaehana wai, hoʻohana ʻia e hoʻomalu i ke kuhikuhi o ka wai, kaomi, kahe ʻana o ka hāmeʻa, ʻo ia ka hana ʻana i ka paipu a me nā mea hana i loko o ke kikowaena (wai, gas, pauka) e kahe a hoʻopaʻa paha i ke kahe o ka hāmeʻa.

ʻO ka valve ka ʻāpana mana o ka pipeline fluid conveying system, hoʻohana ʻia e hoʻololi i ka ʻāpana ala a me ke kuhikuhi kahe waena, me ka diversion, cut-off, throttle, check, diversion or overflow pressure relief functions. Hoʻohana ʻia ka valve no ka hoʻokele wai, mai ka valve honua maʻalahi loa i kahi ʻōnaehana hoʻokele maʻalahi loa i hoʻohana ʻia i nā ʻano valves, kona ʻano like ʻole a me nā kikoʻī, ka nui nominal o ka valve mai ka valve mea liʻiliʻi loa a hiki i ka nui o ka valve pipeline ʻoihana a hiki i 10m. Hiki ke hoʻohana ʻia e hoʻomalu i ka wai, ka mahu, ka aila, ke kinoea, ka lepo, nā ʻano corrosive media, ka metala wai a me ka wai radioactive a me nā ʻano ʻē aʻe o ka kahe o ka wai, hiki ke kaomi hana o ka valve mai 0.0013MPa a i 1000MPa o ke kiʻekiʻe kiʻekiʻe kiʻekiʻe.

Hiki ke hoʻomaluʻia ka valve e nāʻano hoʻoili likeʻole, e like me ka manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic, electro-hydraulic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive; I ke kaomi, ka mahana a i ʻole nā ​​​​ʻano ʻē aʻe ma lalo o ka hana o nā hōʻailona sensor, hana, e like me ke koi o ka mālama ʻana a ʻaʻole hilinaʻi i nā hōʻailona sensor no ka wehe maʻalahi a pani ʻia paha, e hilinaʻi i ke kaʻa a i ʻole ka mīkini hana e wehe a pani i ka valve no ka hāpai ʻana, sliding.
