ʻO ka pahu puka puka cryogenic me kahi pāpale lōʻihi i hoʻolālā ʻia e hana ma nā mahana haʻahaʻa e like me -196 ° C i hana maʻamau e kū i ke anuanu nui a mālama i ka hana kūpono i nā kūlana paʻakikī.Hoʻohana pinepine ʻia kēia mau valve i nā ʻoihana e like me ka hoʻoheheʻe ʻana i ke kinoea kūlohelohe (LNG), ka hana kinoea ʻenehana, a me nā noi cryogenic ʻē aʻe kahi e komo ai nā haʻahaʻa haʻahaʻa. mai ka maloʻo a i ʻole ka palapaʻa ʻana i nā wela haʻahaʻa.Hoʻohui ʻia, koho ʻia nā mea i hoʻohana ʻia i ke kūkulu ʻana i ka valve, e like me nā ʻāpana kūikawā a i ʻole nā plastika haʻahaʻa haʻahaʻa, e mālama i ko lākou ikaika a me ka kūpaʻa i nā wahi cryogenic. ke hoʻāʻo ikaika nei lākou e hōʻoia i hiki iā lākou ke mālama i nā wela wela a me nā pilikia.
1. ʻOi aku ka maʻalahi o ka hale ma mua o ka valve puka, a ʻoi aku ka maʻalahi o ka hana ʻana a mālama.
2.ʻAʻole maʻalahi kaʻili o ka sila eʻaʻahu a me ka'ōpala, a maikaʻi ka hana sila.ʻAʻohe pili pili ma waena o ka disc valve a me ka ʻili o ke kino valve i ka wā e wehe ai a pani ʻia, no laila ʻaʻole koʻikoʻi ka ʻaʻahu a me ka ʻōpala, maikaʻi ka hana sealing, a lōʻihi ke ola lawelawe.
3.I ka wehe ʻana a me ka pani ʻana, liʻiliʻi ka hahau ʻana o ka disc, no laila ʻoi aku ka liʻiliʻi o ke kiʻekiʻe o ka valve hoʻomaha ma mua o ka valve puka, akā ʻoi aku ka lōʻihi o ke kūkulu ʻana ma mua o ka valve puka.
4. ʻO ka wehe a me ka pani pani ʻana he mea nui, ʻo ka wehe ʻana a me ka pani ʻana he hana nui, a lōʻihi ka manawa wehe a pani.
5. He nui ke kū'ē o ka wai, no ka mea, he tortuous ke ala waena i loko o ke kino valve, nui ke kū'ē o ka wai, a nui ka mana.
6.Medium kahe ala I ka manawa o ka nominal kaomi PN ≤ 16MPa, maʻamau apono i mua kahe, a me ka waena kahe i luna mai ka lalo o ka valve disc;i ka manawa o ke kaomi nominal PN ≥ 20MPa, hoʻohana maʻamau i ke kahe kūʻē, a kahe ka waena mai luna o ka disc valve.E hoʻonui i ka hana o ke sila.Ke hoʻohana ʻia, hiki ke kahe wale ka honua valve medium i hoʻokahi ʻaoʻao, a ʻaʻole hiki ke hoʻololi ʻia ke ala kahe.
7. Hoʻopau pinepine ʻia ka diski i ka wā e wehe pono ai.
I ka wā o ka wehe ʻana a me ka pani ʻana o ka pahu kila kila, no ka mea, ʻoi aku ka liʻiliʻi o ka friction ma waena o ka disc a me ka ʻili hoʻopaʻa ʻana o ke kino valve ma mua o ko ka valve puka, ʻaʻole hiki ke ʻaʻahu.
ʻO ka wehe ʻana a i ʻole ka pani ʻana o ka pahu valve he pōkole, a he hana ʻokiʻoki hilinaʻi loa ia, a no ka mea ʻo ka hoʻololi ʻana o ke awa noho valve e like me ka hahau ʻana o ka disc valve, kūpono loa ia no ka hoʻoponopono. o ke kahe ana.No laila, kūpono loa kēia ʻano valve no ka ʻoki ʻoki a i ʻole ka hoʻoponopono a me ka throttling.

Ma ke ʻano he mea hana a me ka mea kūʻai aku, ke hoʻohiki nei mākou e hāʻawi i nā mea kūʻai aku me ka lawelawe ma hope o ke kūʻai aku kiʻekiʻe, me kēia mau mea:
1. Hāʻawi i nā alakaʻi hoʻohana huahana a me nā manaʻo mālama.
2.No nā hemahema i hana ʻia e nā pilikia maikaʻi o ka huahana, hoʻohiki mākou e hāʻawi i ke kākoʻo ʻenehana a me ka hoʻoponopono pilikia i loko o ka manawa pōkole loa.
3.Except no ka pōʻino i hanaʻia e ka hoʻohana maʻamau, hāʻawi mākou i nā lawelawe hoʻoponopono manuahi a me nā pani pani.
4. Ke hoʻohiki nei mākou e pane wikiwiki i nā pono lawelawe o ka mea kūʻai aku i ka wā o ka hōʻoia huahana.
5. Hāʻawi mākou i ke kākoʻo ʻenehana no ka wā lōʻihi, nā lawelawe kūkākūkā pūnaewele a me nā lawelawe hoʻomaʻamaʻa.ʻO kā mākou pahuhopu ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike lawelawe maikaʻi loa a hoʻolilo i ka ʻike o nā mea kūʻai aku i mea ʻoluʻolu a maʻalahi.
