ʻO nā valve kūpono no ka mahana wela -40 ℃～-196 ℃ ua kapa ʻia ʻo ia he mau haʻahaʻa haʻahaʻa haʻahaʻa, a ʻo ia mau valve e hoʻohana mau i nā pāpale ʻāʻī lōʻihi.
Hoʻohana ʻia ka pāpale ʻāʻī lōʻihi e ʻōlelo ai e pili ana ka pahu cryogenic i ka pahu cryogenic pilikia pani pani, cryogenic globe valve, cryogenic check valve, LNG cryogenic valve, NG special cryogenic valve, etc., i hoʻohana nui ʻia i nā mea kanu kemika e like me. e like me 300,000 tons o ka ethylene a me ke kinoea maoli liquefied.ʻO ka hoʻopuka wai haʻahaʻa haʻahaʻa haʻahaʻa e like me ka ethylene, ka oxygen wai, ka hydrogen wai, ke kinoea kūlohelohe liquefied, nā huahana petroleum liquefied, a me nā mea ʻē aʻe. .
Pono nā pāpale ʻāʻī lōʻihi no ka mea:
(1) ʻO ka pāpale ʻāʻī lōʻihi ka hana o ka pale ʻana i ka pahu pahu pahu pahu haʻahaʻa haʻahaʻa, no ka mea, ʻo ka paʻa ʻana o ka pahu hoʻopiha kekahi o nā kī o ka valve haʻahaʻa haʻahaʻa.Inā he leak ma kēia pahu hoʻopiha, e hōʻemi ia i ka hopena hoʻomaha a e hoʻoheheʻe ʻia ke kinoea wai.I ka haʻahaʻa haʻahaʻa, e like me ka emi ʻana o ka mahana, nalo mālie ka elasticity o ka paʻi ʻana, a emi iho ka hana leak-proof e like me ia.Ma muli o ka leakage o ka waena, ua maloʻo ka paʻi ʻana a me ke kumu o ka valve, e pili ana i ka hana maʻamau o ke kumu valve a hoʻoneʻe pū i ke kumu valve e neʻe i luna a i lalo.ʻAkaʻi ʻia ka paʻi ʻana, ka leakage koʻikoʻi.No laila, pono e hōʻoia i ka mahana o ka ʻāpana hoʻopiha ma luna o 8 ° C.
(2) He mea maʻalahi ke ʻano o ka uhi ʻāʻī ʻāʻī lōʻihi no ka uhi ʻana i nā mea insulation anuanu e pale aku ai i ka nalowale ʻana o ka ikehu anu o nā kiwi wela haʻahaʻa.
(3) He mea maʻalahi ka ʻāʻī lōʻihi o ka valve cryogenic no ka hoʻololi wikiwiki ʻana i ka hapa nui o ka valve ma ka wehe ʻana i ka uhi valve.No ka mea, ua hoʻokomo pinepine ʻia nā paipu kaʻina a me nā kiwi i loko o ka ʻāpana anu o nā mea hana i loko o ka \'pahu anuanu\', hiki i ka uhi ʻāʻī ʻāʻī lōʻihi ke hoʻopuka ma ka pā o ka 'pahu anuanu.Ke hoʻololi i nā ʻāpana valve nui, pono wale e wehe a hoʻololi i ka uhi valve me ka ʻole o ka wehe ʻana i ke kino valve.Hoʻopiliʻia ke kino valve a me ka pipeline i loko o ke kino hoʻokahi, e ho'ēmi ana i ka leakage o ka pahu anuanu e like me ka hiki a hōʻoia i ka paʻa o ka valve.
