Elastic properties of metallic hard sealing butterfly valve Profile

Flexible metal seal butterfly valve is a state-level key new products, high-performance flexible metal seal butterfly valve uses a double eccentric, and a special sealing structure oblique elliptical cone. To solve the traditional eccentric butterfly valve in the headstock 0 ° ~ 10 ° the moment still in the sealing surface of the drawbacks of friction sliding contact, the realization of butterflies in the opening moments plate sealing surface that is separated from the closure of the effect of contact that is sealed to extend the service life of sealing performance The purpose of the best.

     Uses:

     For sulfuric acid in the gas pipeline industry: the import and export steel blower, blower relay entrance, electricity and Unicom　valve series, S02 Blower main entrances converter regulation, import and export, such as preheater and the closure of the air-conditioning use.

     System for sulfur-burning sulfuric acid burn in the sulfur, the transformation of drying and absorption section, the sulfur-burning sulfuric acid plant with the preferred brand valves, the majority of users were considered to be: a good sealing performance, running light, the Deputy corrosion, high temperature, easy to operate, flexible, safe and reliable use of the butterfly valve has been a great deal to promote the use of.

     Also widely used: chemical, petrochemical, metallurgy, medicine, food and other industries in the SO2, steam, air, gas, ammonia, CO2 gas, oil, water, salt, alkali, water, nitric acid, hydrochloric acid, sulfuric acid, phosphorus acid medium, such as regulation and control on the road as the use of closure devices.

     Structural characteristics:

     ① three unique eccentric design to the sealing surface so that no friction between the drive to extend the service life of the valve.

     ② torque generated by the flexible seal.

     ③ clever wedge design of the valve clearance has become more tight self-sealing function of sealing surface between the compensatory, zero leakage.

     ④ small size, light weight, compact operation, easy to install.

     ⑤ configured according to user requirements pneumatic, electric devices, to meet the needs of the remote control and program-controlled.

     ⑥ replacement parts could be applied to a variety of media materials, and conducted anti-corrosion lining (lining F46, GXPP, PO, etc.).

     ⑦ continuous structural diversity: for folders, flange, butt welding.
