No ka hoʻohana ʻana i ka mahu kiʻekiʻe, ka wai, catalytic reformers, hydrocrackers, a me nā noi koi ʻē aʻe, kūpono ʻo JLPV forged steel pressure seal check valves. ʻO ka paila, ka aila, kemika, metala, ʻōnaehana ikehu, a me nā noi ʻoihana mana koʻikoʻi, he mau mea liʻiliʻi wale nō ia o nā ʻoihana e hoʻohana pinepine ana i nā kiwi hoʻopaʻa kila kila JLPV. Ke hāʻawi mau nei ʻo Pressure Seal Check Valve i kahi ākea o nā ʻoihana i kahi pale paʻa paʻa paʻa ʻole leak-leak i ka honua koi o ka High Pressure, High Temperature valve applications. ʻO kēia mau kiwikā unidirectional e pale i ke kahe mai ka ʻaoʻao ʻē aʻe. Hana maikaʻi kēia mau mea i nā hoʻonohonoho me ka wikiwiki haʻahaʻa. ʻOiai hiki ke hoʻokomo ʻia nā kiwi hoʻopaʻa i loko o nā pipeline kūpaʻa, hana maʻamau ia no nā kūlana kahe ākea, Pono ke kahe ma lalo o ka disc a kuhikuhi ʻia i luna. ʻO ka manaʻo koʻikoʻi ma hope o nā pahu hoʻopaʻa paʻa, ʻo ia ka wā e hoʻopaʻa ʻia ai nā pahu huki huki mua o ka uhi, e hoʻopaʻa ka uhi ponoʻī i ka pahu hoʻopaʻa sila i ke kino. Hoʻohana ʻia ke kōkua kaomi ʻōnaehana no ka hoʻopili ʻana i ke kaomi hou aku e sila ai i ka gasket. No laila, e emi ana ka hiki ke kahe ma ke kino/bonnet ami ke piʻi aʻe ke kaomi ʻōnaehana.
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 485 ℃
