DBB trunnion pob valve yog dab tsi?
DBB trunnion pob Valveyog lub pob valve tsim tshwj xeeb.
raws li rau Double block thiab bleed valve system, muaj ob lub ntsiab lus los ntawm API6D thiab OSHA.
OSHA txhais ib qhoDBB trunnion pob valveLub kaw lus ua "kev kaw ib txoj kab, cov kav dej, lossis cov yeeb nkab los ntawm kev kaw thiab xauv lossis cim ob lub qhov dej hauv kab thiab los ntawm kev qhib thiab xauv lossis cim lub qhov dej ntws lossis qhov cua hauv kab ntawm ob lub qhov dej kaw".
lubNORTECH DBB trunnion pob valvetsim loslos ntawm kev sib txuas ob lub li qub rau hauv ib lub cev, tus qauv tsim ob lub li qub txo qhov hnyav thiab cov kev xau thaum ua tau raws li OSHA cov kev cai rau kev thaiv ob zaug thiab kev ntshav.
API 6D txhais lub DBB trunnion ball valve System ua "ib lub valve nrog ob lub rooj zaum uas, nyob rau hauv qhov chaw kaw, muab lub foob tiv thaiv kev siab los ntawm ob qho kawg ntawm lub valve nrog ib txoj hauv kev los tso / ntshav qhov chaw ntawm cov chaw zaum."
Cov yam ntxwv tseem ceeb ntawm DBB trunnion pob valve
Ib ChavDBB trunnion pob valve muab ob chav thaiv thiab tso ntshav hauv ib lub valve. Cov qauv no tuaj yeem cais cov kav dej ntawm ob sab ntawm lub valve kom tso pa tawm / tso ntshav ntawm lub qhov ntawm lub valve ntawm cov rooj zaum.
Siv ib lub tshuab ob chav thaiv thiab lub qhov cua tso pa tawm piv rau 3 lub qhov cua sib cais ua rau txuag tau lub sijhawm teeb tsa, qhov hnyav ntawm lub tshuab raj, thiab qhov chaw. Tus qauv tsim no kuj muaj qhov zoo ntawm kev ua haujlwm,
- Muaj tsawg dua qhov muaj peev xwm xau dej hauv ob chav thaiv thiab ntu ntshav ntawm cov kav dej.
- Tag nrho cov khoom siv valve tau muab tso rau hauv ib chav tsev, qhov chaw xav tau rau kev teeb tsa tau txo qis heev yog li tso chaw rau lwm cov khoom siv tseem ceeb.
- Yuav tsum tau siv sijhawm luv dua los ntws dej.
DBB trunnion pob valve yog kev sib xyaw ua ke ntawm ib lossis ntau lub qhov dej thaiv/cais tawm, feem ntau yog lub pob qhov dej, thiab ib lossis ntau lub qhov dej tso tawm/tso pa tawm, feem ntau yog lub pob lossis lub koob qhov dej. Lub hom phiaj ntawm lub kaw lus thaiv thiab lub qhov dej tso pa tawm yog cais lossis thaiv cov dej ntws hauv lub kaw lus kom cov dej ntws los ntawm sab saud tsis mus txog lwm yam ntawm lub kaw lus uas nyob hauv qab. Qhov no ua rau cov kws ua haujlwm tuaj yeem tso pa tawm lossis tso pa tawm lossis ntws cov dej seem ntawm lub kaw lus ntawm sab saud kom ua tiav qee yam haujlwm (kev saib xyuas/kev kho/kev hloov pauv), kev kuaj xyuas, kev hloov pauv dej ntws, kev txhaj tshuaj, kev kuaj xyuas kev ua haujlwm kom paub tseeb tias muaj qhov xau thiab lwm yam.
