DBB kaviri bhora vharafu ndiyo yakapetwa kaviri, kutyora kaviri uye kuburitsa basa vharafu.Kana migumo miviri yevharuvhu iri pasi pekumanikidzwa panguva imwe chete, iyo yepakati mukati mevhavhavhavha inogona kuburitswa kubva muvharuvhu blowdown kana vent valve, uye kumusoro uye kuzasi kwepakati kwevharuvhu hakuzoenderera mberi kupinda muvhavhavha, uye anenge maviri block.Kana kamuri yepakati iri pakumanikidzwa kukuru, chigaro chevhavha chinogona kuburitsa otomatiki kumanikidza, ndiko kuti, kusunungura.Iwo anoshanda kune aviation parafini, mafuta akareruka, gasi rechisikigo, liquefied gasi, pombi gasi, kemikari yepakati, nezvimwe.
Iwo makuru ekuvaka maficha eJLPV DBB maviri bhora vharafu anotevera:
1. 1PC, 3PC uye zvese zvakasungwa muviri kuvaka.
2. Inogona kugadzirwa sebhora rinoyangarara uye bhora rakagadzika.
3. Yakazara yakazaruka kana yakazara kuvhara kaviri block blowdown (DBB) dhizaini.
4. Dhizaini kaviri vharafu ina seal dizaini inovimbisa kuita chisimbiso kwemuviri wevharuvhu, ine zero leakage.
5. Anti-flying stem, emergency injection system yechigaro uye stem, moto wakachengeteka uye anti-static dhizaini, uye muviri wevharuvhu unopiwa nepakati mhango yekuburitsa mudziyo.
Iyo mhando yeJLPV DBB kaviri bhora dhizaini dhizaini yakaita seiyi:
1. Kukura: 2 "kusvika 24" DN50 kusvika kuDN600
2. Kudzvinyirira: Kirasi 150lb kusvika 2500lb PN10-PN420
3. Material: carbon simbi, Stainless simbi uye zvimwe zvakajairika simbi zvinhu.
NACE MR 0175 anti-sarufa uye anti-corrosion simbi zvinhu.
4. Kubatana kunopera: ASME B 16.5 muhuso hwakasimudzwa(RF), Flat face(FF) uye Ring Type Joint (RTJ）
ASME B 16.25 mu screwed end.
5. Zvimiro zvechiso nechiso: zvinoenderana neASME B 16.10.
6. Tembiricha: -29℃ kusvika 425 ℃
Mavharuvhu eJLPV anogona kuve akashongedzerwa negiya opareta, pneumatic actuators, hydraulic actuators, magetsi emagetsi, ekuvhara michina, akawedzera madzinde uye zvimwe zvakawanda zviripo kuti zvizadzise zvinodiwa nevatengi.
