Alakaʻi Valve

He aha ka nohona kiwikā?

ʻO ka kiwikā kahi mīkini hana e kāohi i ke kahe a me ke kaomi i kahi ʻōnaehana a i ʻole ke kaʻina hana. ʻO lākou nā mea maʻamau o ka ʻōnaehana pipeline no ka lawe ʻana i ka wai, ke kinoea, ka mahu, ka lepo, a pēlā aku.

Hāʻawi i nā ʻano kiwikā: nā puka o ka ʻīpuka, kūwā paʻa, palaka kuʻina, pōpō kinipōpō, kiwikā pepeiao, kiwikā hōʻoia, kiwikā diaphragm, kiwikā pinch, kiwikā kōkua, kaomi mālama, a pēlā aku. Nui nā hiʻohiʻona o kēlā me kēia ʻano, me kēlā me kēia nā hana a me nā hana. Hoʻohana ʻia kekahi mau kiʻiona, ʻoiai e hoʻohana ʻē ʻia i kekahi a i ʻole me nā mea hana a i ʻole pneumatic a hydraulic paha.

Nā hana o ka nohona kiwikā ʻo:

kū a hoʻomaka i ke kaʻina

hoʻemi a hoʻonui i ke kahe

ʻaoʻao kahe kāohi

hoʻoponopono i ke kahe a me ke kaomi hana

ʻōnaehana paipu e hoʻokuʻu i kekahi kaomi

Nui nā hoʻolālā kiwikā, nā ʻano a me nā hiʻohiʻona, i loaʻa ka laulā o nā ʻoihana ʻoihana. Kūpono nā mea āpau i hoʻokahi a ʻoi paha nā hana i ʻike ʻia ma luna. He mea waiwai nui nā kiwikā, he mea nui e wehewehe i ka nohona pololei no ka hana, a pono e hana i ka hāmole i nā mea kūpono no ka wai lapaʻau.

Nānā ʻole i ke ʻano, loaʻa nā valves āpau i nā ʻaoʻao maʻamau: ke kino, ka pāpale, ʻoki (nā ʻāpana o loko), ka mea hoʻohana a me ka ʻūlū ʻana. Hōʻike ʻia nā mea kumu o ka nohona ma ke kiʻi ma lalo.

ʻO Valve kahi mea i hoʻohana ʻia e kaohi i ke ʻaoʻao, kaomi a me ke kahe o ka wai i ka ʻōnaehana wai. He mea pono ia e kahe i ke kikowaena (wai, ke kinoea, pauka) e kahe a kū paha i ka hoʻokele a me nā pono hana a hiki ke kaohi i kāna kahe.

ʻO ka kiwikā ka ʻāpana o ka mahele i ka ʻōnaehana halihali wai pipeline, i hoʻohana ʻia e hoʻololi i ka ʻāpana o ke kahawai a me ke ala kahe waena. Loaʻa iā ia nā hana o ka loli, ʻokiʻoki, throttling, hōʻoia, shunt a i ʻole ke kaomi puʻuwai. Aia nā ʻano a me nā kikoʻī o nā kiwikā no ka mālama ʻana i ka wai, mai ka kiwikā kū māmā ʻoi loa i ka ʻōnaehana kaomi akomi paʻakikī loa. ʻO ke anawaena nominal o ke kiwikā mai nā kiʻina hana liʻiliʻi loa i ka valve pipeline ʻoihana me ke anawaena a hiki i 10m. Hiki ke hoʻohana ʻia e kaohi i ke kahe o ka wai, ka mahu, ka ʻaila, ka ʻaila, ka pala, ka pāpā palaʻai, ka mea hoʻoheheʻe wai a me ka wai radioactive. Hiki ke kaomi hana o ka pahū mai 0.0013mpa a i 1000MPa, a hiki ke mahana hana mai c-270 ℃ a 1430.

Hiki ke kāohi ʻia ke kiwikā e nā ʻano hoʻoili like ʻole, e like me ka manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic, electro-hydraulic, pneumatic, spur gear, bevel gear drive, a pēlā aku. nā koi, a i ʻole wehe a pani wale paha me ka hilinaʻi ʻole i ka hōʻailona ʻike. Hilinaʻi ke kiwikā i ka hoʻokele a i ʻole ka hana aunoa e hana i nā ʻāmama a me nā ʻāpana pani e neʻe i luna a i lalo, e pāheʻe, hoʻoluli a i ʻole hoʻohuli, i mea e hoʻololi ai i ka nui o kāna kahawai kahe e ʻike i kāna hana kaohi.
