Histori ea mofuta oa eccentric butterfly valve
The single eccentric butterfly valve ke mofuta oa valve ea serurubele e hlahisoang ho rarolla bothata ba ho petetsa poleiti ea serurubele le setulo sa valve se bohareng ba mola o bohareng.The stem axis e kheloha ho tloha bohareng ba belofo ea serurubele e le hore karolo e ka tlaase ea belofo ea serurubele e se ke ea hlola e e-ba sebaka sa ho potoloha, se qhalakanya le ho fokotsa ho petetsa ha nakoana ha lipheletsong tse ka holimo le tse ka tlaase tsa poleiti ea serurubele le setulo sa valve.
The double offset butterfly valve ke e 'ngoe ea mefuta ea li-valve tsa serurubele, mokokotlo oa stem o tsoa bohareng ba poleiti ea serurubele le bohareng ba 'mele.Phello ea li-eccentricity tse peli e nolofalletsa poleiti ea serurubele ho potlakela ho tsoa setulong ka mor'a hore valve e bulehe, e thusang ho felisa ho penya ho feteletseng le ho senya pakeng tsa serurubele le setulo le ho ntlafatsa bophelo ba setulo.Ho fokotseha ho hoholo ha scraping ho etsa hore ho khonehe ho sebelisa litulo tsa tšepe bakeng sa li-valve tsa serurubele tse habeli, tse ka sebelisoang lits'ebetsong tse phahameng tsa mocheso.
The triple eccentric butterfly valve ke mofuta oa valve ea serurubele, bakeng sa ho kheloha ha boemo ba stem axis ka nako e le 'ngoe, ho etsa hore mokokotlo oa mokokotlo oa serurubele o khelohe holim'a cylindrical axis ea' mele, bokaholimo ba tiiso ea poleiti ea serurubele ke elliptical, sebopeho sa sebaka sa ho tiisa ka hona ke asymmetric, lehlakore le leng le sekametse ho setsi sa 'mele, lehlakoreng le leng le tšoana le setsi sa' mele.Li-valve tse tharo tsa eccentric serurubele li fetola bokaholimo ba ho tiisa, ha e sa le ho tiisa, empa ho tiisoa ha torsion, ho its'etleha holim'a sefahleho sa setulo sa valve ho fihlela phello ea ho tiisa, ho rarolla bothata ba ho lutla ha zero ha setulo sa valve sa tšepe.Kaha khatello ea sefahleho sa ho kopana le khatello e bohareng e lekana, e boetse e rarolla bothata ba khatello e phahameng le mocheso o phahameng, 'me valve ea serurubele e sebelisoa haholo.
