进口高性能调节阀Product Description:

The valve body assembly comprises a valve body assembly and an actuator assembly. The valve body assembly comprises a valve body, a valve stem, a valve disc and a sealing ring. The valve body is provided with a valve seat. The sealing ring is fixed on the valve seat. The upper surface of the sealing ring is provided with an annular groove. The valve disc is made of cemented carbide. The upper end of the valve disc is connected with the valve rod, and the bottom surface of the valve disc is provided with an annular boss matching with the annular groove of the sealing ring, The valve disc and the valve seat are closely fitted through the annular boss and the sealing ring with annular groove. The sealing ring is also provided with a number of throttle through holes connecting the water inlet end and water outlet end of the valve body. The valve rod is connected with the actuator assembly. The actuator assembly is connected with a controller, the controller is connected with a sensor, and one end of the sensor is arranged in the valve body. The regulating valve is easy to control and has good sealing performance. It can effectively avoid the reduction of sealing performance caused by medium erosion during long-term use.

进口高性能调节阀characteristic:

The regulating valve, also known as the control valve, is the final control element in the field of industrial automation process control, which changes the process parameters such as medium flow, pressure, temperature and liquid level by receiving the control signal output by the regulating control unit and with the help of power operation. It is generally composed of actuator and regulating valve. The regulating valve is suitable for air, water, steam, various corrosive media, mud, oil and other media.

进口高性能调节阀Principle:

When the regulating valve is used, the pneumatic actuator drives the valve stem to rotate and drives the valve disc to move downward. The annular boss at the bottom of the valve disc is gradually embedded into the annular groove of the sealing ring to make the valve disc fit with the sealing ring, strengthen the tightness of the valve disc and the sealing ring, and improve the tightness of the regulating valve. When the valve disc and the sealing ring gradually contact, the flow rate of the transmitted medium in the gap between the valve disc and the sealing ring increases, At the same time, part of the medium flows through the throttle through hole, which greatly reduces the impact of the fluid medium on the valve disc and valve seat. The valve disc and sealing ring are finally closed tightly, the throttle through hole is also closed under pressure, and the regulating valve is completely closed, which improves the tightness of the regulating valve, weakens the erosion of the fluid on the valve disc and valve seat, and effectively prolongs the service life of the regulating valve. The controller can analyze according to the data detected by the sensor, Control the pneumatic actuator to control the rise and fall of the valve rod, control the opening and closing degree of the valve, and adjust the flow rate and pressure of the fluid medium as needed.
