Cut off the regulating valveThe working principle of the valve is mainly based on the movement of the valve core to change the flow area of the channel, thereby achieving the regulation of the medium flow rate. When it is necessary to cut off the flow of the medium, the valve core will close the flow channel to ensure that the medium cannot pass through; When it is necessary to adjust the flow rate of the medium, the valve core will move to the corresponding position according to the control signal, changing the flow area of the channel, thereby achieving precise control of the medium flow rate.

　　Cut off the regulating valveStructural characteristics:

Valve body structure: The valve body of the cut-off regulating valve usually adopts a straight through or angular structure, with a compact design and smooth flow channel, which can reduce the resistance loss during the flow of the medium.

Valve core design: The valve core is the core component of the cut-off regulating valve, and its shape and size directly affect the regulating performance and cut-off ability of the valve. Common valve core shapes include spherical, conical, flat, etc. Choose the appropriate valve core shape according to process requirements.

Sealing structure: The sealing structure of the cut-off regulating valve is crucial, as it directly affects the cut-off effect and leakage rate of the valve. There are two common sealing structures: soft seal and hard seal. Soft seal is suitable for low-pressure and low-temperature applications, while hard seal is suitable for high-pressure and high-temperature applications.

Execution mechanism: Cut off control valves are usually equipped with electric, pneumatic, or hydraulic actuators, which can achieve remote control and automated operation. The selection of the executing mechanism should be comprehensively considered based on factors such as process requirements, control accuracy, and reliability requirements.
