M'dziko la ma valve opangidwa ndi mafakitale, ma valve awiri a mpira ndi magazi (DBB) amawonekera ngati njira yodalirika komanso yodalirika yogwiritsira ntchito zosiyanasiyana.Ndi mapangidwe ake apadera komanso magwiridwe antchito, ma valve a mpira a DBB amapereka zabwino zambiri zomwe zimawapangitsa kukhala chisankho chodziwika m'mafakitale osiyanasiyana.
Chimodzi mwazabwino zazikulu za valavu ya mpira wa DBB ndikutha kupereka kudzipatula kawiri, kutanthauza kuti imatha kudzipatula kumtunda ndi kutsika kwamtsinje.Izi ndizofunikira kwambiri pamagwiritsidwe ntchito omwe chitetezo ndi kudalirika ndizofunikira, monga mafuta ndi gasi, petrochemical ndi mafakitale opanga mankhwala.Ma valve a mpira a DBB amapereka kudzipatula kawiri kuti ateteze kuopsa kwa kutayikira ndikuwonetsetsa kukhulupirika kwadongosolo.
Kuphatikiza apo, ma valve a mpira a DBB amakhala ndi ntchito yotulutsa magazi yomwe imachotsa kupanikizika komwe kumatsekeka pakati pazigawo ziwiri zodzipatula.Izi ndizofunikira kwambiri pakukonza ndi kuyesa chifukwa zimathandizira ogwiritsa ntchito kutsitsa dongosolo popanda kufunikira kwa zida kapena njira zina.Kuthekera kwa mpweya wa valve kumathandizanso kukonza chitetezo chokwanira komanso magwiridwe antchito.
Kuphatikiza pa zabwino zake zogwirira ntchito, ma valve a mpira a DBB amadziwikanso kuti ndi olimba komanso odalirika.Zopangidwa ndi zinthu zamtengo wapatali monga zitsulo zosapanga dzimbiri, chitsulo cha carbon, ndi zitsulo za alloy, mavavuwa amatha kupirira kuthamanga kwambiri ndi kutentha ndipo ndi oyenera kugwiritsidwa ntchito m'madera ovuta a mafakitale.Kumanga kwawo kolimba komanso zofunikira zochepa zosamalira zimawapangitsa kukhala kusankha kopanda mtengo kuti agwiritse ntchito kwa nthawi yayitali.
Kusinthasintha kwa valavu ya mpira wa DBB kumafikira kusinthika kwake kumitundu yosiyanasiyana yama media ndi magwiridwe antchito.Kaya akugwira mankhwala owononga, slurries abrasive kapena nthunzi yotentha kwambiri, ma valvewa amapangidwa kuti azigwira ntchito modalirika komanso kutsekedwa kolimba, kuonetsetsa kuti chitetezo ndi chitetezo cha dongosolo.Kukhoza kwawo kugwira ntchito m'malo osiyanasiyana kumawapangitsa kukhala chisankho choyamba panjira zosiyanasiyana zamafakitale.
Kuphatikiza apo, mapangidwe ang'onoang'ono a ma valve a mpira a DBB amawapangitsa kukhala osavuta kukhazikitsa ndikuphatikizana ndi mapaipi omwe alipo.Zimapulumutsa malo komanso zosavuta kuzisamalira, zomwe zimathandiza kuonjezera mphamvu zogwirira ntchito, kuchepetsa nthawi yopuma komanso kuchepetsa kufunika kokonzanso kawirikawiri kapena kusintha.
Mwachidule, valavu ya mpira wa DBB imaphatikiza kudzipatula kwapawiri, magwiridwe antchito, kukhazikika komanso kusinthika, ndikupangitsa kuti ikhale yosinthika komanso yodalirika yosankha ntchito zamafakitale.Kuthekera kwake kutsimikizira kukhulupirika kwa dongosolo, chitetezo ndi magwiridwe antchito kumapangitsa kukhala chinthu chamtengo wapatali m'mafakitale kuyambira mafuta ndi gasi mpaka kukonza mankhwala.Ndi machitidwe awo otsimikiziridwa ndi maubwino ambiri, ma valve a mpira a DBB amakhalabe yankho la chisankho pakudzipatula komanso kuwongolera machitidwe pamakampani.
