Habeli Flange Butterfly Valve
Thehabeli flange serurubele valveke valve e tiileng e lutseng ka serurubele e nang le li-flange tse kopaneng tse lahliloeng lipheletsong ka bobeli, e lumellang khokahano e otlolohileng ea libolte ho phaephe ntle le li-adapter tse ling. Joalo ka li-valve tsohle tse tiileng tse lutseng ka serurubele, ke valve e potolohang ka kotara: disc e chitja e kentsoeng bohareng ba 'mele e sebetsa e le mokhoa oa ho koala, e hokahantsoe le actuator kapa mohele ka shaft e bohareng. Ho potoloha ka botlalo ha likhato tse 90 ho bula kapa ho koala valve ka botlalo bakeng satšebeletso ea ho itšehla thajana.
Ha diski e sa potolohe ho fihlela e fetoha kotara e felletseng, valve e bulehile hanyane - e nolofalletsa ho nepahalataolo ea phalloka dikhutlo tse fapaneng tsa ho bula. Setulo sa rabara se kentswe ka botlalo mmeleng, ho netefatsa ho kwalwa ho tshepahalang ha mahlakore a mabedi ho pholletsa le boholo bohle, ho kenyeletswa le ho hloka matlamaemo a ho sebetsa a vacuum.
Li-valve tsa Nortech tse nang le flange e habeli li entsoe ka tekanyo e telele ea sefahleho le sefahleho ho latela EN 558-1 Series 13, e leng se etsang hore li lokele mefuta e mengata ea lits'ebetso tse akaretsang le tse boima ho kenyeletsoa marang-rang a kabo ea metsi, lifeme tsa kalafo ea metsi, matamo, lifeme tsa motlakase le litsamaiso tsa liphaephe tse bophara bo boholo. Valve e ka sebelisoa e le valve ea ho itšehla thajana, pompo ea ho ntša metsi qetellong ea phaephe, kapa sesebelisoa sa taolo ea phallo. Bakeng sa liphaephe tse bophara bo boholo, tlhophiso ea flange e habeli ke khetho e tloaelehileng.
Ho shebana difahleho nako e telele le EN 558-1 Series 13— moralo oa flange e habeli o fana ka khokahano e tiileng, e its'ehetsang e loketseng haholo liphaephe tse bophara bo boholo le lits'ebetso tsa potoloho e phahameng moo botsitso le ho lumellana ha li-valve li leng bohlokoa.
