1 Nā kikoʻī koʻikoʻi no ke koho ʻana i nā valve

1.1 E wehewehe i ke kumu o ka valve i loko o ka lako a i ʻole ka hāmeʻa

E hoʻoholo i nā kūlana hana o ka valve: ke ʻano o ka medium kūpono, kaomi hana, ka mahana hana a me nā ʻano hana hoʻomalu, a pēlā aku;

1.2 Koho pololei ʻana o ke ʻano valve

ʻO ke koi mua no ke koho pololei ʻana i ke ʻano o ka valve, ʻo ia ka hoʻomaopopo piha ʻana o ka mea hoʻolālā i ke kaʻina hana holoʻokoʻa a me nā kūlana hana. Ke koho nā mea hoʻolālā i nā ʻano valve, pono lākou e hoʻomaopopo mua i nā ʻano kūkulu a me ka hana o kēlā me kēia valve;

1.3 E hoʻoholo i ke ʻano hoʻopau valve

Ma waena o nā pilina wili, nā pilina flange, a me nā pilina hopena i hoʻopili ʻia, ʻo nā mea mua ʻelua ka mea i hoʻohana pinepine ʻia.Nā kiwikā wiliʻo ia hoʻi nā kiwikā me ke anawaena inoa ma lalo o 50mm. Inā nui loa ke anawaena, e paʻakikī loa ke kau a me ka sila ʻana i ka pilina. ʻOi aku ka maʻalahi o ke kau ʻana a me ka wehe ʻana i nā kiwikā pili flange, akā ʻoi aku ka nui a ʻoi aku ke kumukūʻai ma mua o nā kiwikā wili, no laila kūpono lākou no nā pilina paipu o nā anawaena paipu like ʻole a me nā kaomi. He kūpono nā pilina welded no nā kūlana ukana kaumaha a ʻoi aku ka hilinaʻi ma mua o nā pilina flange. Eia nō naʻe, he paʻakikī ke wehe a hoʻouka hou i nā kiwikā welded, no laila ua kaupalena ʻia kā lākou hoʻohana ʻana i nā kūlana kahi e hiki ai iā lākou ke hana maʻamau me ka hilinaʻi no ka manawa lōʻihi, a i ʻole kahi paʻakikī nā kūlana hana a kiʻekiʻe ka mahana;

1.4 Koho ʻana o ka mea valve

I ke koho ʻana i nā mea no ka hale valve, nā ʻāpana kūloko a me nā ʻili sila, me ka noʻonoʻo ʻana i nā waiwai kino (mahana, kaomi) a me nā waiwai kemika (corrosiveness) o ka medium hana, pono e noʻonoʻo ʻia ka maʻemaʻe o ka medium (ke alo a i ʻole ka ʻole o nā ʻāpana paʻa). Eia kekahi, pono ʻoe e nānā i nā lula pili o ka ʻāina a me ka ʻoihana mea hoʻohana. ʻO ke koho pololei a kūpono hoʻi o nā mea valve hiki ke hōʻoia i ke ola lawelawe waiwai loa a me ka hana maikaʻi loa o ka valve. ʻO ke kaʻina koho mea kino valve: hao hoʻolei-kila kalapona-kila kila ʻole, a ʻo ke kaʻina koho mea apo sila: rubber-keleawe-kila huila-F4;

1.5 Nā mea ʻē aʻe

Eia kekahi, pono e hoʻoholo ʻia ka nui o ke kahe a me ka pae kaomi o ke wai e kahe ana ma o ka valve a koho ʻia ka valve kūpono me ka hoʻohana ʻana i ka ʻike i loaʻa (e like me nā papa inoa huahana valve, nā laʻana huahana valve, a pēlā aku).

2 Hoʻolauna i nā kiwikā i hoʻohana pinepine ʻia

Nui nā ʻano kiwikā, me nā kiwikā puka, nā kiwikā poepoe, nā kiwikā throttle, nā kiwikā pepeke, nā kiwikā plug, nā kiwikā poepoe, nā kiwikā uila, nā kiwikā diaphragm, nā kiwikā nānā, nā kiwikā palekana, nā kiwikā hoʻēmi kaomi, nā pahele a me nā kiwikā pani pilikia, ma waena o ia mau mea i hoʻohana pinepine ʻia. Aia nā kiwikā puka, nā kiwikā poepoe, nā kiwikā throttle, nā kiwikā plug, nā kiwikā pepeke, nā kiwikā poepoe, nā kiwikā nānā, nā kiwikā diaphragm, a pēlā aku.

2.1kiwikā puka

ʻO ka valve puka e pili ana i kahi valve nona ke kino wehe a pani (pā valve) e hoʻokele ʻia e ke kumu valve a neʻe i luna a i lalo ma ka ʻili sila o ka noho valve e hoʻopili a ʻoki paha i ke kahawai wai. Ke hoʻohālikelike ʻia me nā valves kū, ʻoi aku ka maikaʻi o ka hana sila ʻana o nā valves puka, ʻoi aku ka liʻiliʻi o ke kūpaʻa wai, emi ka hoʻoikaika e wehe a pani, a loaʻa kekahi hana hoʻoponopono. ʻO lākou kekahi o nā valves kū i hoʻohana pinepine ʻia. ʻO ka hemahema, ʻoi aku ka nui o ka nui a ʻoi aku ka paʻakikī o ke ʻano ma mua o ka valve kū. He maʻalahi ke komo ʻana o ka ʻili sila a paʻakikī hoʻi e mālama, no laila ʻaʻole kūpono ia no ka throttling. Wahi a ke kūlana o ke kaula ma ke kumu valve o ka valve puka, ua māhele ʻia i ʻelua mau ʻāpana: ʻano kumu hāmama a me ke ʻano kumu huna. Wahi a nā ʻano hoʻonohonoho o ka puka, hiki ke māhele ʻia i ʻelua mau ʻano: ʻano wedge a me ke ʻano like.

2.2Kiwikā hoʻōki

ʻO ka valve poepoe he valve e pani ana i lalo. Hoʻokele ʻia nā ʻāpana wehe a pani (nā disc valve) e ke kumu valve e neʻe i luna a i lalo ma ke axis o ka noho valve (ʻili sila). Ke hoʻohālikelike ʻia me nā valves puka, loaʻa iā lākou ka hana hoʻoponopono maikaʻi, ka hana sila maikaʻi ʻole, ka hoʻonohonoho maʻalahi, ka hana maʻalahi a me ka mālama ʻana, ke kūpaʻa wai nui, a me ke kumukūʻai haʻahaʻa. He valve hoʻōki maʻamau ia, hoʻohana nui ʻia i nā pipelines waena a me ke anawaena liʻiliʻi.

2.3 Pākuʻi pōpō

ʻO ka ʻāpana wehe a pani ʻana o ka valve pōpō he pōpō me kahi lua poepoe. Hoʻohuli ka pōpō me ke kumu valve e wehe a pani i ka valve. He ʻano maʻalahi ka valve pōpō, wikiwiki ka wehe ʻana a me ka pani ʻana, maʻalahi ka hana, liʻiliʻi ka nui, māmā ke kaumaha, liʻiliʻi nā ʻāpana, liʻiliʻi ke kūpaʻa wai, maikaʻi ke sila ʻana a maʻalahi ka mālama ʻana.
