Valve ea Butterfly e habeli
Ke Eng Double Eccentric Butterfly Valve ?
Valve ea Butterfly e habeli ke sehlahisoa sa boqapi bo habeli se nang le theknoloji e tsoetseng pele lefatšeng.Valve ena ea serurubele e na le sebopeho se ikhethileng se nang le ts'ebetso e tiileng ea ho tiisa, maemo a pharaletseng a ho sebetsa le torque e tlase ea ts'ebetso.
litšobotsi tse ka sehloohong tsa li-valve tsa serurubele tse habeli tse eccentric ke double eccentric, eo hape e bitsoang double offset disc design.
e lumella disc ho tloha setulong ho fokotsa torque le ho roala ha setulo, ke molemo o moholo ha o bapisoa le li-valve tsa serurubele tse konkrehileng.
Khatello ea "disc" e lokolloa ka mor'a ho bula likhato tse 'maloa tse fokotsang ho roala ha disc seal.Ho feta moo, moralo o fokotsa khatello ea tiiso e netefatsang li-torque tse tlase tse sebetsang.
The shaft sealing e ka nkeloa sebaka ka tlas'a khatello ho nolofalletsa tlhokomelo e bonolo.Ho tiisoa ha EPDM ho tiisa ho tiisa ho tsoa ka hare le ka ntle, 'me litiiso tsa NBR li sireletsa khahlanong le litšila le maro a tsoang ka ntle.
Li-bearings tsa PTFE tse fokolang li netefatsa hore li-torque tse tlaase tsa ts'ebetso 'me shaft e sirelelitsoeng e etsa hore e tšoarelle ka nako e telele kaha ha ho na libaka tsa tšepe tse sa koaeloang tse pepesehileng mecheng ea litaba.
