【Handle clip-on fluorine butterfly valve】 Product Overview
Handle clip-on fluorine-type butterfly valve with split two-piece body combination, the valve seat and body lining integration, the valve work, only the plastic valve seat and the plastic-plastic disc contact with the media, the valve can withstand the lining material Introduced medium corrosion, the use of quadrupole seal structure and at the sealing surface at the temperature with anti-aging of the SI rubber elastic pad, completely zero leakage of the medium, with tight sealing performance, long service life.
【Handle folder clamp fluorine butterfly valve】 Features
1, the central line butterfly valve for the entire disc and valve seat in the 360 ° circle concentric (center line), with two-way sealing function, pressure, flow can be adjusted;
2, eccentric butterfly valve for the two-dimensional direction of the eccentric cam effect will seal Produce enough seal than the pressure, and as the working pressure increases, the seal pair produces enough seal pressure, and as the working pressure increases, the sealing effect is more ideal;
3, four loading elastic seal, absolutely guaranteed Zero leakage inside and outside of the valve;
(1) Reasonable interference between the special transition curve of the shaft head and the disc circumference connection and the valve seat;
(2) The elastic end face of the shaft head adopts the rigid washer with elastic O-ring and shoulder; Rubber pad combination;
(3) radial shaft O-ring with a combination of metal pads;
(4) the valve seat inlaid elastic body of the groove;
4, adjustable positioning with the pin, accurate positioning, structure simple.
【Handle clip-on fluorine butterfly valve】 Scope of application
D71F46 handle wafer clamp fluorine butterfly valve for temperature ≤ 120 ℃, the nominal pressure ≤ 1.6MPa food, medicine, chemicals, petroleum, electricity, light textile paper and other water supply and drainage, gas pipeline for regulating the flow and cut off the role of the media, Applicable to various concentrations of aqua regia, hydrofluoric acid and a variety of organic acids, acids, strong oxidants and other media.
