Flexible metal seal butterfly valve performance briefings
Flexible metal sealing butterfly valve is a national key new product, high-performance flexible metal sealing butterfly valve with a double eccentric and a special oblique cone oval seal structure. It solves the defect that the traditional eccentric butterfly valve is still in sliding contact friction at the moment when the opening and closing is 0 ° ~ 10 °, so that the sealing surface of the butterfly valve can be separated at the moment of opening and the effect of closing the contact is sealed, thus prolonging the service life and sealing performance Good purpose. Uses: Used for gas pipeline in sulfuric acid industry: entrance and exit of furnace blower, relay fan inlet and outlet, electric demister series and Unicom valve, S02 main blower inlet and outlet, converter adjustment, preheater inlet and outlet adjustment and cutoff gas usage. It is the preferred brand of valve for sulfur-burning sulfuric acid plant. It is considered by the majority of users as: sealing performance, light operation, corrosion resistance, high temperature resistance, easy operation, Flexible, the use of safe and reliable butterfly valve, has been widely promoted. Also widely used in chemical, petrochemical, metallurgy, medicine, food and other industries in the SO2, steam, air, gas, ammonia, CO2 gas, oil, water, salt water, lye, sea water, nitric acid, hydrochloric acid, sulfuric acid, Medium and other media as a regulatory device and interception device. Structural characteristics of the metal seal butterfly valve: ①three-eccentric design of the unique friction between the sealing surface transmission, extending the service life of the valve. ② produced by the elastic seal torque. ③ ingenious wedge design so that the valve has a more closed automatic sealing function, the sealing surface has a compensatory, zero leakage. ④ small size, light weight, lightweight operation, easy to install. ⑤ can be configured according to user requirements pneumatic and electric devices to meet the needs of remote control and program control. ⑥ replacement parts material can be applied to a variety of media, and can be lining anti-corrosion (lining F46, GXPP, PO, etc.). ⑦ continuous structure diversification: the folder, flange, butt welding.
