Cryogenic Globe Valve Hoʻonui ʻia ka Bonnet no -196 ℃
✧ Hōʻike
Cryogenic Globe Valve me Extended Bonnet i hoʻohana ʻia no -196 ℃, hoʻohana nui ʻia i ka ʻoihana kemika, ka ʻaila, ke kinoea maoli, ka metallurgy, ka mana uila a me nā ʻoihana ʻē aʻe. Hoʻohana ʻia ka pahu kila kila i hoʻopili piha ʻia, a ʻo ke kino valve a me ka puka i hana ʻia i nā ʻāpana kila forged. He maikaʻi ka hoʻopaʻa ʻana o ka valve, ke kūpaʻa corrosion ikaika a me ke ola lawelawe lōʻihi. He maʻalahi kona hale, liʻiliʻi ka nui, maʻalahi e hoʻouka a mālama. Hiki ke hoʻololi i ka ʻīpuka a hiki ke ʻoki loa i ke kahe waena me ka leakage. ʻO ka pahu kila kila kila he ākea ākea ākea a me ke kaomi hana kiʻekiʻe, a hiki ke hoʻohana ʻia no ka mana kahe waena ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa a me nā kūlana kiʻekiʻe.
✧ Nā hiʻohiʻona o ka API 602 Cryogenic Globe Valve Extended Bonnet no -196℃
1. ʻOi aku ka maʻalahi o ka hana ma mua o ka valve honua, 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 honua, akā ʻoi aku ka lōʻihi o ke kūkulu ʻana ma mua o ka valve honua.
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, ia mea 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, e hoʻohana maʻamau i ke kahe kūʻē, a kahe ka waena i lalo mai ka piko o ka disc valve. E hoʻonui i ka hana o ke sila. I ka wā e hoʻohana ai, hiki ke kahe wale ka honua valve medium ma ka ʻaoʻao hoʻokahi, a ʻaʻole hiki ke hoʻololi ʻia ke ala kahe.
7. Hoʻopau pinepine ʻia ka diski i ka wā e wehe pono ai.
✧ Pono o API 602 forged steel globe valve
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 ka valve honua, 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.

✧ Mahope o ke kuai ana
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 ka hoʻoponopono manuahi a me nā lawelawe 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.
