The electric piston type flow regulating valve is a piston type structure, and the piston type control valve should be adjusted by a crank slider mechanism, and the closing slider is a cylinder or cone piston. In the cylinder of the valve body, it can be guided by a guide rail to move axially along the center of the pipeline to achieve the function of adjusting the flow rate and reducing the pressure.
The piston-type control valve has reliable sealing performance. When the regulating valve is in a fully closed state, it is guaranteed that there is no leakage. Under normal operating conditions, the piston-type control valve has no jamming and harmful vibration to ensure the safe and reliable operation of the equipment. The service life is not less than 30 years. The piston-type control valve has good anti-blocking ability.
The driving mode of the piston control valve is motor driving. The electric device of the piston type control valve includes a motor, a reduction turbine, a mechanical limit adjustment mechanism, a torque control mechanism, a stroke control mechanism, an opening indicating mechanism and a manual electric conversion mechanism device. The electric device of the piston control valve adopts an integrated motor design and is equipped with a local operation control box.
The valve body of the piston type control valve is a streamlined axisymmetric flow channel, and the fluid can be well guided in the valve body, which can significantly reduce noise and vibration. Ensure that the valve has good anti-cavitation characteristics even at high pressure differences, and its allowable cavitation coefficient should not be greater than 0.4Mpa.
The performance characteristics of LHS941X pressure regulating valve are mainly introduced above. When we all choose this kind of valve, we should all have a clear understanding of our kind of valve, and the correct way to operate and use our kind of valve.
