Ukwethulwa kwe-Pneumatic Flange Metal Hard Seal Butterfly Valve

I-valve yohlobo lwe-pneumatic flange metal seal hard seal butterfly yakhiwe i-quarter-stroke pneumatic piston actuator kanye nomzimba wevalve uvemvane onama-eccentric amathathu. Idizayinelwe ngomgomo we-eccentric wezinhlangothi ezintathu ukuze wenze umzila wokunyakaza kwesikhala wendawo evalwayo ube okahle, futhi akukho ukungqubuzana futhi akukho ukungqubuzana phakathi kwezindawo zokuvala. Ukuphazamiseka, okuhambisana nokukhethwa okufanele kwezinto zokufaka uphawu, kuqinisekisa ukuthi ukusebenza kokuvala, ukumelana nokugqwala, ukumelana nokushisa okuphezulu nokumelana nokugqoka kwe-valve uvemvane kuqinisekisiwe ngokuthembekile.

I-axis yesiqu se-valve ye-pneumatic flanged metal butterfly valve hard seal isuswa endaweni yokuvala yepuleti lovemvane futhi isuswe e-eksisi yephaseji yomzimba. I-axis yokuzungezisa isihlalo se-valve kanye ne-axis yomzimba ye-valve yakha i-eccentric angle, ngaleyo ndlela yakhe i-eccentricity kathathu. Lapho i-valve uvemvane ivulwa ukusuka ku-0°～90°, indawo yokuvala yepuleti uvemvane izohlukaniswa nendawo yokuvala yesihlalo sevalvu ngesikhathi sokuvulwa. Uma ivaliwe ku-90° ～0°, indawo eyisiyingi evalekayo yepuleti lovemvane izothintana futhi icindezele ikhoni yesihlalo sevalvu. Shape uphawu. Ngakho-ke, akukho ukungqubuzana phakathi kwesihlalo se-valve nendawo yokuvala yepuleti le-butterfly, okuqeda ukuthi kungenzeka ukuguga nokuvuza.
