Triple eccentric pneumatic valve structure and characteristics

Pneumatic triple eccentric valve belongs to high performance valve, it through a variety of driving gear to drive the rotation of the valve spindle, valve shaft and driven plate channel do - the valve body ° rotation of the scope, to achieve the purpose of open and close the valve, the control system for the pipe flow medium. Triple eccentric metal hard seal valve for ultra high performance, can be widely used in the generator, steam, hot and cold air smelting, chemical engineering, power generation, environmental protection and other projects in the pipeline, the suitable medium including all kinds of corrosive, non - corrosive fluid. Three eccentric structure of pneumatic valve three eccentric structure characteristics of the pneumatic valve: has the following advantages:, small volume, light weight, good cutting performance. , plate, sealing surface designed to relative axis of plate is a truncated cone surface, make the sealing surface of the valve seat sealing surface and has certain contact Angle, the Angle of contact face evenly around the circumference of a circle is equal to a narrow cuneate, circumference and plate the seal line is reasonably elliptic curve, longitudinal sealing compensation effect on both. , plate, sealing surface under the closed position, force uniform, high bearing capacity; Plate in the process of opening, sealing face each point from the valve seat sealing surface finish at the same time, no crowded card phenomenon, basic no friction, small open torque. As a result, low cost, good sealing performance, long service life. , all kinds of sealing structure for choice, ensure the reliability and service life. Valve sealing ring have integral soft seal ( PTFE , C- TFE , G- TFE) And hardening of metal plate, monolithic + carbide, suitable for all kinds of working condition. And can realize two-way sealing function, can adjust, and have cut off function. , actuators, low friction, high efficiency, large thrust and good security. , actuators to poach, combination ( Manual) The direction of the design, can guarantee the optional installation and flexible control. And simple, reliable, integrated travel directives and the combination of limit switches and solenoid valve installation, no external piping, reduce the leakage point. , a variety of actuator form choice, meet different user requirements. , convenient assembly and maintenance, superior performance and low cost.
