The elastic metal seal butterfly valve is a national key new product. The high performance elastic metal seal butterfly valve adopts a double eccentricity and a special oblique cone elliptical seal structure. Solve the traditional eccentric butterfly valve in the opening and closing 0 ° ~ 10 ° instant sealing surface friction is still in the shortcomings of friction, to achieve the instant opening of the butterfly plate in the sealing surface that is separated, close the contact that is the effect of sealing, to extend the service life, the most sealing performance Good purpose.
use:
For the sulfuric acid industry gas pipeline: furnace front fan inlet and outlet, relay fan inlet and outlet, electric defogging series and connection valve, S02 main blower inlet and outlet, converter adjustment, preheater inlet and outlet adjustment and cut-off gas usage.
The sulphur-burning, conversion and dry-sucking sections used in sulphur-based sulphuric acid plant are the preferred brands of valves for sulphur-based sulphuric acid plants. They are considered by the majority of users as having good sealing performance, light operation, secondary corrosion, high temperature resistance, and easy operation. Flexible, safe and reliable butterfly valves have been widely used.
Also widely used in chemical, petrochemical, smelting, pharmaceutical, food and other industries in SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid The medium pipe is used as a regulating and shutoff device.
Structural features of metal hard seal butterfly valve:
1 The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces, extending the service life of the valve.
2 elastically sealed by torque.
3 Ingenious wedge design makes the valve more tight and automatic sealing function, sealing surface between the compensation, zero leakage.
4 small size, light weight, lightweight operation, easy installation.
5 According to user requirements, pneumatic and electric devices can be configured to meet the needs of remote control and program control.
6 Replacement parts Materials can be applied to various media, and can be lining anti-corrosion (lining F46, GXPP, PO, etc.).
7 Diversified continuous structures: clips, flanges, butt welds.
