Fluorine-butterfly handle flange butterfly valve flange joint structure, lined with integration of valve body, valve seat and valve core, valve work, only the body lining and lining plastic butterfly plate and the media contact, the valve can bear the medium corrosion of lining materials is introduced, using quadrupole seal structure and the sealing surface with heat-resistant anti-aging SI rubber elastic gasket, completely reach the zero leakage of medium, with tight sealing performance, long service life. Fluorine-butterfly handle flange butterfly valve product figure

fluorine-butterfly handle 1, center line butterfly valve flange butterfly valve structure characteristics for the entire disc and seat in 360 & deg; Circular concentric ( The midline) Which have the function of two-way sealing, pressure and flow rate can be adjusted freely; 2, eccentric butterfly valve for two-dimensional direction of eccentric CAM effect sealing pair causes enough sealing pressure, and with the increase of working pressure, sealing deputy produce enough sealing pressure, and with the increase of working pressure, the sealing effect is more ideal; 3, 4 class load elastic seal, absolutely guarantee the zero leakage of Industrial Valves inside and outside; （ 1) Shaft head, butterfly plate peripheral joint special transition curve and the seat of the reasonable interference; （ 2) Shaft head end use elastic o-rings and rigid shaft shoulders gasket, elastic rubber pad combination; （ 3) Shaft radial adopt the combination of o-rings and metal pads; （ 4) Seat of article in elastic body slot; 4, with adjustable billiard positioning, accurate positioning and simple structure. Fluorine-butterfly handle flange butterfly valve applicable scope is widely used in temperature & le; 120 ℃, nominal pressure & le; 1. 6 mpa in food, medicine, chemical, petroleum, electric power, textile and paper for adjusting flow rate on water supply and drainage, gas pipe and block the effect of medium, aqua regia, suitable for all kinds of concentration of sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acid medium, strong acid, strong oxidizer, etc. Fluorine-butterfly handle flange butterfly Industrial Valves manufacturer recommendations
