Ivalve yebhola ephindwe kabini yeDBB kukuvala kabini, ikhefu eliphindwe kabini kunye nevalve yokusebenza yokukhulula. Xa iziphelo zombini zevalve ziphantsi koxinzelelo ngaxeshanye, isithuba esiphakathi kumngxuma wevalve sinokukhutshwa kwivalve okanye ivelufa yevalve, kwaye umsinga onyukayo kunye nosezantsi kwevalve awusayi kuqhubeka nokungena kumngxuma wevalve, kwaye phantse kabini ibhloko. Xa igumbi eliphakathi liphantsi koxinzelelo oluphezulu, isihlalo sevalve sinokukhulula ngokuzenzekelayo uxinzelelo, oko kukuthi, ukukhulula. Zisebenza kwi-aviation parafini, i-oyile elula, igesi yendalo, igesi engamanzi, igesi yombhobho, i-chemical medium, njl.
Iimpawu eziphambili zokwakha ze-JLPV DBB ivelufa yebhola ephindwe kabini zilandelayo:
1. I-1PC, i-3PC kunye nayo yonke i-welded body building.
2. Ziyakwazi ukuyilwa njengebhola edadayo kunye nebhola esisigxina.
3. Ukuvula ngokupheleleyo okanye ukuvala ngokupheleleyo ibhloko yokuvuthela (i-DBB) uyilo.
4. Ivalve ephindwe kabini uyilo lwesitywina esine iqinisekisa ukusebenza kokutywina komzimba wevalvu, ngokuvuza kweqanda.
5. Isiqu esichasene ne-flying, inkqubo ye-injection engxamisekileyo yesihlalo kunye nesiqu, ukhuseleko lomlilo kunye noyilo lwe-anti-static, kunye nomzimba we-valve unikezelwa nge-cavity ephakathi ukukhupha isixhobo.
Uluhlu lwe-JLPV DBB yoyilo lwevalvu yebhola ephindwe kabini luloluhlobo lulandelayo:
1. Ubungakanani: 2 "ukuya ku-24" DN50 ukuya kwi-DN600
2. Uxinzelelo: Iklasi 150lb ukuya 2500lb PN10-PN420
3. Izinto eziphathekayo: i-carbon steel, insimbi engenasici kunye nezinye izinto eziqhelekileyo zetsimbi.
I-NACE MR 0175 i-anti-sulfur kunye ne-anti-corrosion metal materials.
4. Uqhagamshelo luphela: ASME B 16.5 kubuso obuphakanyisiweyo (RF), ubuso obuFlat (FF) kunye noLuhlu lweRingi ngokudibeneyo (RTJ）
I-ASME B 16.25 kwisiphelo esikrufu.
5. Imilinganiselo yobuso ngobuso: ihambelana ne-ASME B 16.10.
6. Ubushushu: -29℃ ukuya ku-425 ℃
Iivalvu ze-JLPV zinokuxhotyiswa nge-gear operator, i-pneumatic actuators, ii-hydraulic actuators, ii-actuator zombane, izixhobo zokutshixa, izikhondo ezongeziweyo kunye nezinye ezininzi ziyafumaneka ukuhlangabezana neemfuno zabathengi.
