ʻEwalu ʻano o ka hoʻokaʻawale ʻana o nā kumu hoʻohālike o ka pahu mana

ʻO ka mea hiki ke mālama i ke kahe o ka wai i loko o ka pipeline ma ka hoʻololi ʻana i ka ʻāpana o ka pipeline i kapa ʻia ʻo valve a i ʻole ʻāpana valve. ʻO ka hana nui o ka valve i loko o ka pipeline ʻo ia: pili ʻia a ʻoki ʻia paha; Kāohi i ka hoʻihoʻi ʻana o ka media; Hoʻoponopono i ke kaomi, kahe a me nā ʻāpana ʻē aʻe o ka waena; Ka hoʻokaʻawale ʻana, ka hui ʻana, a i ʻole ka hāʻawi ʻana i ka media; Kāohi i ke kaomi waena ma mua o ka waiwai i ʻōlelo ʻia, i mea e mālama ai i ke alanui a i ʻole ka ipu, ka palekana o nā lako.
Me ka hoʻomohala ʻana o ka ʻepekema hou a me ka ʻenehana, ka valve i ka ʻoihana, ke kūkulu ʻana, ka mahiʻai, ka pale aupuni, ka noiʻi ʻepekema a me ke ola o nā kānaka a me nā ʻano ʻē aʻe o ka hoʻohana ʻana i ka mea maʻamau, ua lilo i mea hana kanaka i kēlā me kēia wahi o nā huahana mechanical āpau. .
Hoʻohana nui ʻia nā valves i ka ʻenehana pipeline. Nui nā ʻano valve no nā kumu like ʻole. ʻOi aku i nā makahiki i hala iho nei, ua kūkulu ʻia nā hale hou, nā mea hou a me nā hoʻohana hou o nā valves. I mea e hoʻohui ai i nā kūlana hana, akā no ka koho pololei a me ka ʻike ʻana o ka valve, i mea e hoʻomaʻamaʻa ai i ka hana, hoʻonohonoho ʻana a me ka hoʻololi ʻana, ʻo nā kikoʻī valve ka standardization, generalization, serialization direction development.
Hoʻokaʻawale ʻana o nā valves:
Ua hānau ʻia ka valve Industrial ma hope o ka hana ʻana o ka ʻenekini mahu, i nā makahiki he iwakālua a kanakolu paha, ma muli o ka ʻaila, kemika, ka mana mana, ke gula, nā moku, ka ikehu nuklea, aerospace a me nā ʻano ʻē aʻe o ka pono, e kau i nā koi kiʻekiʻe ma ka ʻO ka valve, i noiʻi ai nā kānaka a me ka hana ʻana i nā palena kiʻekiʻe o ka valve, kona mahana hana mai ka mahana mua -269 ℃ a 1200 ℃, a hiki i ka 3430 ℃; ʻO ke kaomi hana mai 1.33 × 10-8Pa (1 × 10ˉ10mmHg) ma supervacuum a hiki i 1460MPa i ka superpressure. ʻO ka nui o ka valve mai 1mm a 6000mm a hiki i 9750mm. Valve mea mai ka hao hao, kalapona kila, hooulu ana i ka titanium a me ka titanium alloy kila, a me ka loa corrosion kila, haʻahaʻa wela kila a me ka wela pale kila kiwikā. ʻO keʻano hoʻokele o ka valve mai ka hoʻomohala ikaika i ka uila, pneumatic, hydraulic, a hiki i ka mana o ka papahana, ea, mamao mamao, a me nā mea'ē aʻe.
E like me ke kuleana o ka valve wehe a kokoke, he nui nā ʻano hoʻohālikelike o ka valve, ma aneʻi e hoʻolauna i kēia mau mea.
