The use and structural characteristics of mental seat butterfly valve

The high performance mental seat butterfly valve uses a double eccentric and a special oblique cone elliptical seal structure. The problem that the sealing surface of the traditional eccentric butterfly valve is still in sliding contact friction when opening and closing 0° ~ 10° is solved. The sealing surface of the butterfly disc is separated when opening and sealed when closing, so as to prolong the service life and achieve the best sealing performance.

USES:

Used for gas pipeline in sulfuric acid industry: furnace front blower inlet, relay fan inlet, electric defogging series and unicom valve, main blower inlet, converter regulation, preheater inlet and cut-off gas use.

Used in sulfur burning, conversion and dry absorption section of sulfur acid production system, it is the first choice of valve for sulfur acid production device. It is considered by the majority of users as a butterfly valve with good sealing performance, light operation, auxiliary corrosion, high temperature resistance, convenient operation, flexible, safe and reliable use, which has been widely used.

It is also widely used in chemical, petrochemical, smelting, medicine, food and other industries, such as SO2, steam, air, gas, ammonia, CO2 gas, oil, water, salt water, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media on the pipeline as a regulating and intercepting device.

Structural features:

1 The unique DESIGN of three-way ECCENTRicity makes the sealing surface frictionless transmission, prolonging the service life of the valve.

2 Elastic seal produced by torque.

3The CLEVER WEDGE DESIGN MAKES THE VALVE HAVE THE automatic sealing FUNCTION of THE tighter and tighter, the sealing surface between COMPENSatory, zero leakage.

4 Small size, light weight, easy to operate, easy to install.

5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.

6. The material of replacement parts can be applied to various media, and can be lined with anti-corrosion (lining F46, GXPP, PO, etc.).

7 Continuous structure diversification: clamp, flange, butt welding.
