ʻO kahi ʻano valve hiki ke hoʻohana ʻia i nā kūlana haʻahaʻa haʻahaʻa (196 degere) ʻo ia ka JLPV forged steel haʻahaʻa haʻahaʻa puka pā.ʻO nā valve wela haʻahaʻa ka mea nona ka mahana hana ma lalo o -40 degere.ʻO kekahi o nā ʻāpana nui o ka mīkini i ka petrochemical, ka hoʻokaʻawale ʻana i ka ea, ke kinoea maoli, a me nā ʻāpana ʻē aʻe ʻo ka valve.Hoʻoholo kona maikaʻi inā hiki i ka hui ke hana mau, palekana, a me ka loaʻa kālā.ʻO ke ʻano nui o ka valve ka koi no ka mālama cryogenic o nā ʻāpana a me nā ʻāpana āpau.
ʻO nā hiʻohiʻona hana nui o JLPV Forged steel valve penei:
1. Loaʻa ka hoʻolālā piha piha a me ka pahu maʻamau (hōʻemi ʻia).
2. ʻEkolu hoʻolālā bonnet no ka pahu puka paʻa, kiwi honua a me ka pahu pahu
--Bolted Bonnet, welded bonet and pressure sila hoʻolālā
3. ʻO ke kino kumu Y no ka valve puni honua paʻa, ke kino lōʻihi a me ke kumu lōʻihi no nā kiwi hoʻopaʻa ʻia a pau.
4. Loaʻa ka hoʻolālā flanged integral a me ka hoʻolālā hopena flanged
ʻO ka laulā o ka JLPV Forged steel valves design penei:
1. Nui: 1/2 "a 2" DN15 a DN1200
2.Pressure: Papa 800lb a 2500lb PN100-PN420
3.Material: Carbon steel a me ke kila kila a me nā mea kūikawā'ē aʻe.
NACE MR 0175 nā mea metala anti-sulfur a me nā mea metala anti-corrosion
4. Hoʻopau ka pilina:
Hoʻopau ʻia ke kumu wili i ka ASME B16.11
Hoʻopau ʻia (NPT,BS[) i ANSI/ASME B 1.20.1
ʻO ka hope weld butt (BW) i ka ASME B 16.25
Hoʻopau ʻia (RF, FF, RTJ) iā ASME B 16.5
5. Temperature: -29 ℃ i 580 ℃
Hiki ke hoʻolako ʻia nā kīwaha JLPV me ka mea hoʻohana, nā mea hana pneumatic, nā mea hana hydraulic, nā mea hana uila, nā bypasses, nā lako laka, nā huila kaulahao, nā ʻōpala lōʻihi a me nā mea ʻē aʻe he nui i loaʻa e hoʻokō i nā koi o nā mea kūʻai aku.
