ʻO ka pahu hoʻomaha hydraulic RV-10 me ka pahu hydraulic pahu pahu kumu pipeline hoʻomaha hoʻomaha hoʻomaha i hoʻopaʻaʻia i loko o ka pahu hoʻomaha pololei.
Nā kiko no ka nānā ʻana
ʻO ka wehewehe ʻana o "valve" he mea hoʻohana e hoʻokele i ke kuhikuhi, kaomi a me ke kahe o ka wai i loko o kahi ʻōnaehana wai. ʻO nā pāpaʻi nā mea hana e hoʻoheheʻe ai i ka mea waena (wai, kinoea, pauka) i loko o nā paipu a me nā mea hana e kahe a paʻa paha, a hiki ke hoʻomalu i kona kahe. ʻO ka valve kahi māhele mana i loko o ka pipeline fluid transport system, i hoʻohana ʻia e hoʻololi i ka ʻāpana keʻa o ka ʻaoʻao a me ke kuhikuhi o ke kahe o ka waena, a aia nā hana o ka diversion, cut-off, adjustment, throttling, non-return. , hoʻohuli a i ʻole ka hoʻoluhi ʻana i ke kaomi. Hoʻohana ʻia nā kiwi no ka mālama ʻana i ka wai mai ka valve ʻoki ʻoki maʻalahi loa a hiki i nā ʻano valve āpau i hoʻohana ʻia i nā ʻōnaehana hoʻokele paʻakikī paʻakikī, a ʻo kā lākou mau anawaena nominal mai nā kiwi mea kani liʻiliʻi a i nā kiwi pipeline ʻoihana me nā anawaena o 10m. Hiki ke hoʻohana ʻia nā pāpaʻi e hoʻomalu i ke kahe ʻana o nā ʻano wai like ʻole, e like me ka wai, ka mahu, ka aila, ke kinoea, ka lepo, ka media corrosive, ka metala wai a me ka wai radioactive. Hiki ke piʻi ka hana o nā valves mai ka 1.3х10MPa a i ka 1000MPa, a hiki ke piʻi ka mahana hana mai ka wela haʻahaʻa haʻahaʻa o -269 ℃ i ke kiʻekiʻe o 1430 ℃. Hiki ke hoʻomaluʻia ka valve e nāʻano hoʻoili likeʻole, e like me ka manual, electric, hydraulic, pneumatic, worm gear, electromagnetic, electromagnetic-hydraulic, electric-hydraulic, pneumatic-hydraulic, spur gear a me bevel gear drive. Ma lalo o ka hana o ke kaomi, ka mahana a i ʻole nā ʻano ʻē aʻe o ka ʻike ʻana i nā hōʻailona, hiki iā ia ke hana e like me nā koi i koho mua ʻia, a i ʻole e wehe a pani ʻole me ka hilinaʻi ʻole i nā hōʻailona ʻike. Ke hilinaʻi nei ka valve i ka hoʻokele a i ʻole ka mīkini e hoʻoneʻe i ka wehe a me ka pani ʻana i nā ʻāpana e neʻe i luna a i lalo, paheʻe, koli a ʻōwili paha, pēlā e hoʻololi ai i ka nui o kāna wahi kahe e ʻike ai i kāna hana mana.
