Puka Puka Puka Puka Puka Puka Puka Puka palupalu

wehewehe pōkole:

ʻO ka ʻīpuka ʻīpuka he ʻano valve kahi e neʻe kū pololei ai ka lālā pani (puka) ma ka laina waena o ke kahawai.Hiki ke hoʻohana wale ʻia ka valve puka no ka wehe piha a me ka pani piha ʻana i ka pipeline, ʻaʻole hiki ke hoʻohana ʻia no ka hoʻoponopono ʻana a me ka throttling.

Hoʻohana nui ʻia ka valve puka no ka ʻoki ʻana i nā mea hana me ke anawaena o DN ≥ 50mm, a i kekahi manawa hoʻohana ʻia nā ʻīpuka puka no ka ʻoki ʻana i nā mea me nā anawaena liʻiliʻi.

ʻO ka ʻāpana wehe a pani ʻana o ka ʻīpuka ʻīpuka ka puka, a ʻo ka neʻe ʻana o ka ʻīpuka e kū pololei i ke kuhikuhi o ka wai.Hiki ke wehe piha a pani piha ʻia ka valve puka, ʻaʻole hiki ke hoʻoponopono ʻia a hoʻopaʻa ʻia paha.Loaʻa i ka ʻīpuka ʻelua ʻili hoʻopaʻa.ʻO nā ʻaoʻao hoʻopaʻa ʻelua o ka valve puka maʻamau i hoʻohana pinepine ʻia e hana i kahi ʻano wili.'Oko'a ka huina o ka wedge me nā palena valve, ma'amau 50, a me 2°52' ke ki'eki'e ka mahana waena.Hiki ke hana 'ia ka 'īpuka o ka 'īpuka wili, i kapa 'ia he 'īpuka pa'a;hiki ke hana ʻia i puka e hiki ai ke hana i kahi liʻiliʻi o ka deformation e hoʻomaikaʻi ai i kāna hana hana a hoʻopaʻi i ka deviation o ke kihi ʻili o ka sila i ka wā o ka hana.Kapa ʻia ka pā i ka puka elastic.ʻO ka valve puka ka mea hoʻokele nui no ka kahe ʻana a i ʻole ka lawe ʻana i ka nui o ka pauka, nā mea palaoa, nā mea granular a me nā ʻāpana liʻiliʻi.Hoʻohana nui ʻia ia i ka metallurgy, mining, nā mea kūkulu hale, ka palaoa, ka ʻoihana kemika a me nā ʻoihana ʻē aʻe e kāohi i ka loli kahe a ʻoki koke.

ʻO nā kiwi puka puka e pili pono ana i nā ʻano o nā ʻīpuka kila i hoʻolei ʻia, hiki ke hoʻokaʻawale ʻia i loko o nā ʻīpuka paʻa, nā ʻīpuka pā like, a me nā ʻīpuka ʻīpuka e like me ka hoʻonohonoho ʻana o ka ʻili o ka sila.Hiki ke hoʻokaʻawale ʻia ka ʻīpuka puka i: ​​ʻano ʻīpuka hoʻokahi, ʻano ʻīpuka pālua a me ke ʻano ʻīpuka elastic;Hiki ke hoʻokaʻawale ʻia ka valve parallel i ka ʻano puka hoʻokahi a me ke ʻano ʻīpuka pālua.E like me ke kūlana o ke kaula o ka pahu valve, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻano: piʻi puka puka piʻi a me ka valve puka puka ʻole.

Ke pani ʻia ka valve puka, hiki ke hoʻopaʻa ʻia ka ʻili sealing wale nō e ka puʻe waena, ʻo ia hoʻi, e hilinaʻi ana i ke kaomi maʻamau e kaomi i ka ʻili hoʻopaʻa o ka pā pā i ka noho valve ma kēlā ʻaoʻao e hōʻoia i ka hoʻopaʻa ʻana o ka. ili hoʻopaʻa, ʻo ia ka hoʻopaʻa ʻana iā ia iho.ʻO ka hapa nui o ka valve i hoʻopaʻa ʻia i ka sila, ʻo ia hoʻi, i ka wā i pani ʻia ai ka valve, pono e kaomi ʻia ka ʻīpuka i ka noho valve e ka ikaika o waho, i mea e hōʻoia ai i ka hoʻopaʻa ʻana o ka ʻili.

Ke neʻe nei ka ʻīpuka o ka ʻīpuka ʻīpuka ma kahi laina pololei me ke kumu valve, kahi i kapa ʻia ʻo ka ʻīpuka ʻīpuka hoʻokiʻekiʻe (i kapa ʻia hoʻi ʻo ka ʻīpuka puka puka piʻi).ʻO ka mea maʻamau, aia kahi kaula trapezoidal ma luna o ka mea hāpai, a ma o ka nut ma ka piko o ka valve a me ke ala alakaʻi ma ke kino valve, ua hoʻololi ʻia ka neʻe ʻana i kahi laina laina pololei, ʻo ia hoʻi, ua hoʻololi ʻia ka torque hana. i loko o ka hana hana.

Ke wehe ʻia ka valve, i ka wā e like ai ke kiʻekiʻe o ke kiʻekiʻe o ka pā pā i ka 1: 1 mau manawa o ke anawaena o ka valve, ua wehe ʻole ʻia ke ala o ka wai, akā ʻaʻole hiki ke nānā ʻia kēia kūlana i ka wā o ka hana.Ma ka hoʻohana maoli ʻana, hoʻohana ʻia ka piko o ke kumu valve ma ke ʻano he hōʻailona, ​​​​ʻo ia hoʻi, ʻo ke kūlana kahi e neʻe ʻole ai ka pahu valve e lawe ʻia ʻo ia i kona kūlana hāmama loa.I mea e noʻonoʻo ai i ka laka paʻa ma muli o ka hoʻololi ʻana o ka mahana, e wehe maʻamau i ke kūlana kiʻekiʻe, a laila huli hoʻi i ka huli 1/2-1, e like me ke kūlana kiwi piha.No laila, ua hoʻoholo ʻia ke kūlana piha o ka valve e ke kūlana o ka puka (ʻo ia hoʻi, ka hahau).

Ma kekahi mau pani puka puka, ua kau ʻia ka ʻāʻī ma luna o ka pā ʻīpuka, a ʻo ka hoʻololi ʻana o ka huila lima e hoʻohuli i ke kumu valve e ʻōwili, a hāpai ʻia ka pā ʻīpuka.Ua kapa ʻia kēia ʻano valve he rotary stem gate valve a i ʻole he valve stem stem ʻeleʻele.
