Hōʻike ʻia nā kiwi puka paʻi paʻi e ka wili huakaʻi, i hoʻoneʻe ʻia me ka hana ʻana o ka nati kumu.Holo pololei ka wili i ke ala o ke kahe.
ʻO nā kiwi puka he papalua sila hoʻolālā, ʻo ia ka mea maʻamau i ka haʻahaʻa haʻahaʻa haʻahaʻa ke hāmama piha, hāʻawi i ka paʻa paʻa i ka wā i pani ʻia.
Hoʻohana ʻia nā kiwi puka paʻi paʻi no ka lawelawe puʻe kiʻekiʻe, maʻamau no nā kaomi ma luna o 100 bar.ʻO ka hiʻohiʻona kūʻokoʻa o ka bonnet seal pressure ʻo ia ka hoʻomaikaʻi ʻana o ke sila ʻana o ke kino-bonnet i ka piʻi ʻana o ke kaomi kūloko i loko o ka pahu.
ʻO nā noi nui: ʻoihana petrochemical, nā mokuahi, ka holo ʻana o ka paila, ka aila a me nā noi kinoea, nā mana mana.
ʻO nā ʻano mea maʻamau i ʻike ʻia: ka mahu, ka condensate, ka wai hānai boiler
He 900, 1,500 a me 2,500 paona ka helu puʻe maʻamau o ka valve.
ʻO ke ʻano o ka hoʻolālā puka puka JLPV penei:
1. Nui: 2 "a 48" DN50 a DN1200
2.Pressure: Papa 900lb a 2500lb PN160-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: ASME B 16.5 ma ke alo i hoʻokiʻekiʻe ʻia (RF), ka maka palahalaha (FF) a me ke Ring Type Joint (RTJ)
ʻO ASME B 16.25 i ka hopena o ka wiliwili ʻana.
5. He alo a he alo: e like me ASME B 16.10.
6. Temperature: -29 ℃ i 580 ℃
Hiki ke hana ʻia nā valve JLPV i nā ʻano mea like ʻole e hoʻokō i nā koi like ʻole mai nā mea kūʻai aku, ʻoi aku ka maʻamau o NACE.
Hiki ke hoʻolako ʻia nā kīwaha JLPV me ka mea hoʻohana, pneumatic actuators, Hydraulic actuators, Electric actuators, bypasses, laka paʻa, chainwheels, extended stems a me nā mea ʻē aʻe he nui e hoʻokō i nā koi o nā mea kūʻai aku.
