Structure and working principle of regulating valve

Working material of control valve: Control valve is a device used to control the flow, pressure and temperature of fluid medium. It adjusts the flow of fluid by changing the opening of the valve, thus realizing the control of the fluid system.

Regulating valves are widely used in petroleum, chemical industry, electric power, metallurgy, pharmacy, food and other industrial fields, and play an important role.

The regulating valve mainly has two parts, the first part is the actuator, and the second part is the valve body, in which the valve body plays a very important role in regulation and will have very close contact with the medium, and the actuator changes the throttle area by pushing the valve body to change its position, thus achieving the regulation effect.

Structural standard: The structural standard of control valve includes the design and manufacturing requirements of valve body, bonnet, valve seat, valve core and other components. Size standard: the size standard of control valve includes the specification of size parameters such as valve diameter, length, height and width. Material standard: the material standard of control valve includes the material selection and performance requirements of valve body, bonnet, seat and spool. Test standard: The test standard of control valve includes sealing performance, pressure resistance and corrosion resistance.

The regulating valve has the following characteristics:

1, high precision: the regulating valve can realize accurate control of the fluid with high control precision.

2. Good reliability: the regulating valve has simple structure, reliable operation and long service life.

3. Strong adaptability: the regulating valve can adapt to the fluid control requirements of different media and different working conditions.

4. Good adjustability: the opening of the regulating valve can be adjusted as needed to realize flexible flow control.

5. Fast response speed: The response speed of the regulating valve is fast, which can quickly adjust the flow of fluid.

6. Convenient maintenance: The control valve is easy to maintain, which can reduce downtime and maintenance costs.
