Li-valve tsa Ball tse Flanged li ka Sebelisoa Bakeng sa Eng: Likopo

Valve ea Ball e Flanged ke eng

Valve ea bolo e nang le flangeke mofuta oa valve e potolohang ka kotara e sebelisang bolo e se nang letho, e phunyehileng, le e potolohang ho laola phallo ea mokelikeli. Poleloana "flanged" e bolela mokhoa oa ho hokahanya valve: e na le li-flange lipheletsong ka bobeli, tse tlameletsoeng ho li-flange tse tsamaellanang liphaepheng kapa lisebelisoa. Moralo ona o netefatsa khokahano e matla, e sa lutleng, e etsang hore li-valve tsa bolo tse flanged li be tse loketseng bakeng sakhatello e phahamenglemocheso o phahamenglits'ebetso.

Bolo e ka hare ho valve e na le lesoba le kenang bohareng ba yona. Ha valve e butswe, lesoba le tsamaisana le tsela eo phallo e tsamayang ka yona, e leng se dumellang mokelikeli ho feta. Ho potoloha mohele kapa actuator ka di-degree tse 90 ho kwala valve, ho beha lesoba le otlolohileng ho phallo le ho le thibela. Di-valve tsa bolo tse nang le di-flanged di tsebahala ka ho tshepahala ha tsona, tshebetso e potlakileng, le ho theoha hanyane ha kgatello.

Li-valve tsa bolo tse nang le Flanged li ka sebelisoa bakeng sa eng?

Li-valve tsa bolo tse nang le flanged li phetha karolo ea bohlokoa taolong ea mokelikeli:

• Ho behwa ka thoko:Koala phallo nakong ea tlhokomelo kapa maemo a tšohanyetso.
• Taolo ea Phallo:Meralo ea li-port tsa V e nolofalletsa ho thiba.
• Taolo ea Khatello:Ho mamella ho phahama ha khatello e phahameng.

Bokhoni ba tsona ba ho sebetsana le maemo a feteletseng (mohlala, mocheso o bakang cryogenic, marotholi a bohale) li etsa hore li be bohlokoa haholo liindastering tse hlokang botšepehi le polokeho.

Qetello

Li-valve tsa bolo tse nang le Flangedke likarolo tse feto-fetohang, tse tšoarellang, le tse sebetsang hantle bakeng sa litsamaiso tsa taolo ea mokelikeli. Ka likhetho tse boholo bo tlohang ho ½” ho isa ho 48″, thepa e kang tšepe e sa ruseng le PTFE, le litekanyetso tsa khatello ho fihlela ho 5,000 PSI, li fihlela litlhoko tsa liindasteri ho tloha ho oli le khase ho ea ho phekolo ea metsi. Moralo oa tsona o otlolohileng o netefatsa ho kenngoa ho sireletsehileng, ha litlhophiso tse tsoetseng pele (mohlala, tse kenngoeng ka har'a trunnion, tse tharo) li atolosa ts'ebetso ea tsona. Ebang ke ho arola liphaephe, ho laola phallo, kapa ho laola mouoane o phahameng, li-valve tsa bolo tse otlolohileng li fana ka ts'ebetso e ke keng ea bapisoa lits'ebetsong tsa bohlokoa.
