Pneumatic sanitary control valves are usually composed of the following main components:
1. Valve body: The valve body is the main part of the pneumatic sanitary control valve, usually made of stainless steel or other corrosion-resistant materials. A fluid channel is designed inside the valve body to control the flow of the fluid.
2. Spool: The spool is a moving part of the valve body, which adjusts the opening and closing of the valve through the movement of the spool, thereby controlling the flow rate and pressure of the fluid.
3. Pneumatic actuator: Pneumatic actuator is the key component of pneumatic sanitary control valve, usually composed of cylinder, piston, air source interface, etc. The compressed air is used as the power source to drive the movement of the cylinder and piston to control the valve.
4. Positioner: Positioner is a device used to monitor the valve position and feed back to the control system, which can achieve accurate control and adjustment of the valve position.
5. Accessories: Pneumatic sanitary control valves are usually equipped with some accessories, such as manual operation devices, dampers, electro-pneumatic converters, etc., to assist in the operation and control of the valve.
The working principle of the pneumatic sanitary control valve is to open and close the valve through the pneumatic actuator, so as to control the flow rate and pressure of the fluid. The following is the working principle of the pneumatic sanitary control valve:
1. Control signal input: When the system needs to control the fluid, the control system will send a signal to the pneumatic actuator to indicate the opening of the valve.
2. Air supply: After receiving the control signal, the pneumatic actuator will obtain compressed air from the air source interface as a power source.
3. Piston movement: Compressed air enters the cylinder and pushes the piston movement. The movement of the piston causes the spool to move and changes the opening of the valve.
4. Fluid control: With the change of valve opening, the flow rate and pressure of the fluid will also change accordingly. By controlling the opening of the valve, precise control and adjustment of the fluid can be achieved.
5. Feedback signal: The positioner will monitor the position of the valve and send the feedback signal to the control system. The control system can adjust the control signal according to the feedback signal to realize the accurate control of the valve position.
