2, Torque e nyane ea switjha.
Likarolo tse ka nkeloang sebaka li kopane ebile li na le chelete e ngata
Boitsebiso bo nano-modified ho ntlafatsa khatello

5, 'mele oa valve o teteaneng bakeng sa khanyetso e phahameng ea khatello
6, 100% teko ea khatello pele ho pepa
7, Likarolo tsa 'mele le ho tiisa li tšoaroa ka ho khetheha bakeng sa ho sebetsa hantle.
Eccentric butterfly valve ke mokhoa o tloaelehileng oa ho laola, o khetholloang ke moralo oa sekhahla sa li-valve bakeng sa sebopeho sa eccentric, ts'ebetsong ea ho bula le ho koala e ka etsa hore valve e tiise hantle ka thuso ea moralo oa eccentric. Serurubele se akaretsang le se bohareng se bolela sebopeho sa lepheo la li-valve bakeng sa axis ea symmetric.
Ha ho bapisoa le li-valve tsa serurubele tse akaretsang, li-valve tsa serurubele tse eccentric li khetholloa ka sebopeho se rarahaneng le litšenyehelo tse phahameng tsa tlhahiso. Leha ho le joalo, lits'ebetsong tse sebetsang, e boetse e na le ts'ebetso e phahameng ea taolo le ts'ebetso ea ho tiisa, haholo-holo ka khatello e phahameng, mocheso o phahameng, li-viscosity le mecha e meng e rarahaneng, ts'ebetso ea eccentric butterfly valve e hlahella haholoanyane, ho finyella taolo e nepahetseng ea phallo le khatello. taolo.
Molemo oa eccentric butterfly valve ke ofe?
1.Small flow resistance:
hobane spool ea eccentric serurubele valve e etselitsoe hore e be centrifugally e fapaneng le setulo ka sebaka se itseng, ha sepakapaka se phalla ka valve, tsela ea ho phalla e khuts'oane ho feta ea li-valve tse ling, kahoo e etsa khanyetso e nyenyane;
2. Ho tiisa ho ka tšeptjoang:
Nakong ea ts'ebetso ea ho koala ha valve ea eccentric butterfly, khatello e kholoanyane e tla thehoa pakeng tsa spool le setulo, e leng se ka khonang ho tiisa ho tiisa hantle; ha e ntse e buloa, haholo-holo e itšetlehile ka khohlano pakeng tsa spool le setulo ho netefatsa ho tiisa.
3.Tahlehelo e nyane ea khatello:
eccentric butterfly valve e nang le sebopeho sa eccentric e ka fetola pina ea phallo e mahareng ho ea bonyane, kahoo e fokotsa ho hanyetsa le tahlehelo ea khatello.
