ʻO DBB pahu pālua pālua ka pili pālua, ʻelua hoʻomaha a hoʻokuʻu i ka hana hana.Ke hoʻokau ʻia nā ʻaoʻao ʻelua o ka valve i ka manawa like, hiki ke hoʻokuʻu ʻia ka waena o ka lua valve mai ka valve blowdown a i ʻole vent valve, a ʻaʻole e hoʻomau ke komo ʻana o ke kahawai i luna a me lalo o ka valve, a aneane papalua poloka.Ke piʻi kiʻekiʻe ke keʻena waena, hiki i ka noho valve ke hoʻokuʻu aunoa i ke kaomi, ʻo ia hoʻi, hoʻokuʻu.Ua pili ia i ka aila lele, ka aila māmā, ke kinoea maoli, ke kinoea liquefied, ke kinoea pipeline, ke kinikini, etc.
ʻO nā hiʻohiʻona hana nui o JLPV DBB pālua pōpō pōlele e hahai nei:
1. 1PC, 3PC a me ka hana kino welded a pau.
2. Hiki iā lākou ke hoʻolālā ʻia e like me ka pōpō lana a me ka pōpō paʻa.
3. Hoʻolālā piha hāmama a pani piha ʻelua poloka blowdown (DBB).
4. Hoʻolālā pālua ʻehā seal e hōʻoia i ka hana sealing o ke kino valve, me ka leakage zero.
5. Anati-lele kumu, pilikia pilikia injection nenoaiu o ka noho a me ke kumu, ahi palekana a me ka anti-static manao, a me ka valve kino ua hoolakoia me ka waena lua e hoʻokuʻu mea.
ʻO ka laulā o ka JLPV DBB hoʻolālā pōlele pālua penei:
1. Nui: 2 "a 24" DN50 a DN600
2. Paʻi: Papa 150lb a 2500lb PN10-PN420
3. Mea: carbon steel, stainless steel a me nā mea metala maʻamau.
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 ka Ring Type Joint (RTJ)
ASME B 16.25 ma ka hope wili.
5. Nā ana he alo a he alo: e like me ASME B 16.10.
6. Ka wela: -29 ℃ i 425 ℃
Hiki ke hoʻolako ʻia nā valves JLPV me ka mea hoʻohana, nā mea hana pneumatic, nā mea hoʻokele hydraulic, nā mea hana uila, nā lako laka, nā ʻōpala lōʻihi a me nā mea ʻē aʻe he nui i loaʻa e hoʻokō i nā koi o nā mea kūʻai aku.
