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 māhele mana i loko o 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, ka hoʻohuli ʻana a i ʻole ka overflow relief, a me nā mea ʻē aʻe. nā mea i hoʻohana ʻia i nā ʻōnaehana automation paʻakikī.

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 nā mea i hoʻolei ʻia i nā kiwi hao, nā kiwi kila, nā kiwi kila 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. , nā kiwi maʻamau maʻamau ʻole.

Aia ʻo Valve i ka ʻōnaehana wai, hoʻohana ʻia e hoʻomalu i ke kuhikuhi o ka wai, kaomi, kahe ʻana o ka mea hana, e hana i ka paipu a me nā mea hana i loko o ke kikowaena (wai, gas, pauka) e kahe a hoʻopaʻa i ka 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 mālama ʻana i ka wai, mai ka valve honua maʻalahi loa a i kahi ʻōnaehana hoʻokele maʻalahi loa i hoʻohana ʻia i nā ʻano valves, kona ʻano a me nā kikoʻī, ka nui o ka nui o ka valve mai ka valve mea liʻiliʻi loa i ka nui o ka pipeline ʻoihana. valve a hiki i 10m.Hiki ke hoʻohana ʻia e hoʻomalu i ka wai, ka mahu, ka aila, ke kinoea, ka lepo, nā ʻano media corrosive, ka metala wai a me ka wai radioactive a me nā ʻano ʻē aʻe o ka kahe wai, hiki ke kaomi hana o ka valve mai 0.0013MPa a i 1000MPa o ultra-kiʻekiʻe. kaomi, hiki i ka mahana hana ke C-270 ℃ o ka wela haʻahaʻa haʻahaʻa a hiki i 1430 ℃ o ka wela 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;Ma 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 hoʻopaʻa ʻana a ʻaʻole i hilinaʻi ʻia i nā hōʻailona sensor no ka wehe maʻalahi a pani ʻia paha, hilinaʻi i ke kaʻa a i ʻole ka mīkini hana e wehe ai a pani i ka valve no ka hāpai ʻana, ka hoʻoheheʻe ʻana, kahi a i ʻole ka neʻe ʻana o ka rotary, i mea e hoʻololi ai i ka nui o ke awa i mea e ʻike ai i ka hana mana.
