Pneumatic Control Valve Structure, Characteristics and Application Introduction
Pneumatic control valve compressed air as a power source, cylinder as an actuator, and with the help of electrical valve positioners, converters, solenoid valves, holding valves and other accessories to drive the valve, to achieve switching or proportional adjustment, receiving industrial automation control system control signals to complete the adjustment of pipeline media: flow, pressure, temperature and other process parameters.
Pneumatic control valve structure of the main components
- Valve body: the valve body is the main part of the pneumatic control valve, usually made of cast iron, carbon steel or stainless steel and other materials. The valve body is equipped with inlet and outlet channels to control the flow of fluid.
- Spool: spool is a pneumatic control valve to control fluid flow and pressure of the components, usually made of stainless steel or copper. The structure of the spool has a straight-through and right-angle type two kinds, straight-through type is suitable for large flow occasions, and right-angle type is suitable for small flow occasions.
- Pneumatic actuator: Pneumatic actuator is the key component in pneumatic adjustment valve, it controls the opening and closing of spool by receiving gas signal. Pneumatic actuator usually consists of a cylinder and a piston. When the pneumatic actuator receives a gas signal, the piston in the cylinder will be subject to the action of air pressure, thus changing the position of the spool to achieve the purpose of controlling the flow and pressure of the fluid.
- Piping: Piping is the component that connects the pneumatic control valve with the fluid system, usually made of steel or stainless steel pipe. The role of piping is to guide the fluid from the inlet to the valve body, and then from the valve body to guide out.
Pneumatic control valve features
- Simple control: The control method of pneumatic control valve is simple and direct, easy to operate and manage.
- Fast Response: Its extremely fast response time enables it to respond quickly to control signals and realize precise flow, pressure or temperature adjustment. Intrinsically Safe: Due to their design principle and working mechanism, pneumatic control valves are inherently intrinsically safe and require no additional explosion-proof measures.
- High Reliability: In general, pneumatically operated control valves have high reliability and stability, and are suitable for control needs in various industrial environments.
- Energy saving and environmental protection: To a certain extent, the operation of the pneumatic control valve can realize the effective use of energy, which is conducive to energy saving and emission reduction.
Pneumatic control valve applications
- Steam control: Used in steam pipelines to regulate the flow and pressure of steam as needed to achieve temperature control of the heating system.
- Petrochemical industry: Used in oil and gas processing, according to the need to control the flow and pressure of the fluid, so as to realize the control of the petrochemical production process.
- Chemical industry: Used in various chemical reactions, according to the need to control the flow and pressure of the reactants, so as to realize the control of chemical reactions.
- Food industry: Used in various food production processes to control the flow and pressure of various fluids, thus realizing the control of the food production process.
