I ka hapa nui o nā ʻoihana i hoʻonohonoho ʻia i ke kaʻina hana, ʻoi aku ka valve ma mua o kahi mea hoʻomalu kahe—he mea palekana hana ia. Inā paha ma ka hoʻomaʻemaʻe petrochemical, ka lawe ʻana i ke kinoea, a i ʻole nā ​​​​ʻōnaehana mālama wai kaumaha, hilinaʻi nui ka hana o kahi valve i kona mau ʻāpana: ʻo ke kino, ke kumu, ka noho, a me ka hoʻopili ʻana e hāʻawi i ka lōʻihi a me ka hilinaʻi sila.

Ma ke kahua, ʻoi aku ka nui o ka hilinaʻi ma mua o nā mea ʻē aʻe. He ʻoiaʻiʻo loa kēlā i nā noi aila a me ke kinoea ma ʻAmelika ʻĀkau, kahi i hōʻike ʻia ai nā valves i ke kaomi kiʻekiʻe, nā wai ʻino, a me ke kaʻapuni wela i kēlā me kēia lā.

I ka neʻe ʻana o nā hale hana ʻoihana i nā hana akamai—i hoʻokele ʻia e ka automation, ka nānā mamao, a me ka mālama wānana—ke hoʻoponopono hou ʻia nei nā ʻōnaehana valve me nā actuators akamai a me nā ʻāpana kaohi.

Ma nā hiʻohiʻona mālama pono ma nā ʻoihana hana, ʻaʻole pinepine ka hāʻule ʻana o nā ʻōnaehana valve ma muli o ke kino valve ponoʻī. Akā, ʻo ia pinepine nā ʻāpana kūloko—nā kumu valve e ʻeha nei mai ka ʻaʻahu ʻana o ka ʻili, nā noho valve e nalowale ana ka concentricity ma lalo o nā pōʻaiapuni kaomi, a i ʻole ka haki ʻana o nā glands packing ma muli o ka luhi wela—e alakaʻi ana i ka paʻa ʻole o ka ʻōnaehana, ka leakage, a i ʻole nā ​​​​pani i hoʻolālā ʻole ʻia.

I ka wā e pili ana i nā hoʻolālā mālama valve, nui nā hana e hāʻule mau ana i ka pahele like—kūʻai i nā ʻāpana makepono, hoʻololi pinepine, a hoʻopau i ka downtime. Akā i nā ʻoihana me ka hana mau a i ʻole ka ʻike kiʻekiʻe o ka ʻōnaehana, ʻoi aku ka nui o ke kumukūʻai huna o ka hoʻololi pinepine ma mua o ka mālama kālā ma ke kumukūʻai mua.

I nā hana ʻoihana hou, mai nā hale hana hana kemika a hiki i nā kikowaena mana, ʻo ka hana o kahi ʻōnaehana valve ka mea hoʻoholo pinepine ma waena o ka hana maʻalahi a me ka manawa hoʻomaha pipiʻi. ʻOiai ke loaʻa nei i ke kino valve ka hapa nui o ka nānā ʻana, ʻo ia ka...

Ke hoʻonui ʻia nā lako hana ʻoihana, ua kuhikuhi ʻia ka hapa nui o ka nānā ʻana i nā ʻōnaehana automation, nā polokalamu kaohi, a i ʻole nā ​​​​hoʻololi ʻana o ka pipeline nui. Eia nō naʻe, ma lalo o kēia mau hoʻomaikaʻi i ʻike ʻia aia kahi ʻano o nā ʻāpana i kakaʻikahi ke hana i nā poʻomanaʻo akā he mea nui ia no ka hana maoli: nā ʻāpana valve maʻamau.

Ma nā ʻoihana e like me nā lāʻau lapaʻau, ka hana ʻana i ka meaʻai, a me ka metallurgy wela kiʻekiʻe, ʻike nā ʻenekinia ma ke kahua ʻaʻole pinepine ka hemahema o ka valve e hoʻomaka me ke kino. ʻO nā ʻāpana liʻiliʻi e hāʻule mua—nā kumu kūlou, nā glands hoʻopaʻa e leaka ana, a i ʻole nā ​​​​noho i pau. ʻAʻole kēia he mau pilikia theoretical; ke kumu nei lākou i nā pani maoli, nā hemahema batch, a me nā lohi hana.
