DBB Pob Valve

DBB Pob Valve, lub npe tag nrho Ob Chav Block thiab Bleed Ball Valve, yog txheej ntawm ob chav so thiab los ntshav pob ua haujlwm hauv ib qho ntawm qhov siab tshaj valve. Nws tuaj yeem tsis tsuas yog cais cov kua dej kom ntseeg tau, tab sis kuj ua rau cov khoom seem tawm lossis siab thaum xav tau, ua tiav ob zaug lav kev ua haujlwm.

Lub ntsiab kom zoo dua ntawm lub valve no yog nws ob chav thaiv tsim, los ntawm ob txoj kev ywj pheej sealing khub, nyob rau hauv lub xeev kaw los tsim ib tug ob chav tiv thaiv kom ntseeg tau tias qhov nruab nrab tsis xau, yog li zoo heev txhim kho kev nyab xeeb thiab kev cia siab ntawm lub valve. Nyob rau tib lub sijhawm, nws txoj haujlwm Bleed yog icing ntawm lub ncuav mog qab zib, lub valve kab noj hniav yog nruab nrog tshwj xeeb los ntshav interface, uas yooj yim rau kev tso tawm qhov seem nruab nrab lossis siab hauv cov kab noj hniav thaum xav tau, muab kev yooj yim zoo rau kev tu, tu thiab kho. overhaul ntawm lub valve.

DBB pob li qub tau siv dav hauv cov roj, roj, tshuaj lom neeg, hluav taws xob thiab lwm yam kev lag luam, uas feem ntau muaj cov kev xav tau siab rau kev nyab xeeb thiab kev ntseeg siab ntawm li qub. Nrog nws cov kev ua tau zoo thiab kev ua haujlwm ruaj khov, DBB pob valve tau txais kev lees paub dav dav thiab kev ntseeg siab.

Hais txog kev xaiv cov khoom siv, lub cev lub cev, lub pob thiab lwm yam tseem ceeb ntawm DBB pob valve tuaj yeem ua los ntawm stainless hlau, carbon hlau, hlau alloy thiab lwm yam ntaub ntawv los hloov mus rau qhov chaw ua haujlwm sib txawv thiab kev xav tau ntawm kev tshaj tawm. Nyob rau tib lub sijhawm, raws li qhov xav tau tiag tiag, nws tseem tuaj yeem nruab nrog phau ntawv, hluav taws xob, pneumatic thiab lwm yam kev tsav tsheb kom tau raws li qhov xav tau ntawm kev ua haujlwm sib txawv.

Txhawm rau kom muaj kev ruaj ntseg mus ntev ntawm DBB pob valve, koj raug qhia kom ua haujlwm tsis tu ncua thiab tshuaj xyuas. Nrog rau kev tu lub valve sab hauv, lubricating lub swb valve qia thiab sealing nto, hloov cov ntsaws ruaj ruaj, thiab lwm yam, kom ntseeg tau tias kev khiav hauj lwm kev ua tau zoo thiab sealing kev ua tau zoo ntawm lub valve ib txwm ua tau raws li cov qauv tsim.
