Adjust the pneumatic valve is mainly used in what areas

Adjust the pneumatic valve is in the field of industrial automation process control, by accepting conditioning control unit of the output control signal, from engine operation to change medium flow rate, pressure, temperature, liquid level of the process parameters such as final control element.

regulating pneumatic valve according to the itinerary features can be divided into: straight stroke and stroke. Straight travel include: single-seat pneumatic valve, pneumatic valve, two-seat sleeve pneumatic valve, Angle valve, tee pneumatic valve, pneumatic diaphragm valve; Quarter-turn include: pneumatic valve, pneumatic valve, eccentric rotary pneumatic valve. Adjust according to the drive mode can be divided into pneumatic valve: pneumatic regulating pneumatic valve, electric pneumatic valve and hydraulic regulating pneumatic valve; By adjusting the form can be divided into: external regulation regulation, cut, cut type; According to the flow characteristic can be divided into: linear, percentage, parabola, quick opening, etc. Adjust the pneumatic valve is suitable for the air, water, steam, a variety of corrosive medium, mud, oil, etc.

in the automatic control of modern factory, regulating pneumatic valve plays a more important role, the plant production depends on the correct flow of the liquid and gas distribution and control. Control whether exchange of energy, pressure reducing, or is a simple container loading, will need some control elements to complete. Control element can be thought of as 'physical' automatic control. In low - energy level regulator and high - level necessary for the execution of flow fluid control function, control components to complete the necessary power amplification effect.
regulating pneumatic valve control element is a widely used type. Other control elements including metering pump, damper and louver damper ( A kind of pneumatic valve forms) , variable slope of fan blade, current control device, and is different from the pneumatic motor positioning device of the valve.

although adjust the use of pneumatic valve widely, regulating system of other units probably did not like it less maintenance workload. In many systems, regulating pneumatic valve through working conditions such as temperature, pressure, corrosion and pollution is more serious than in other parts, however, when the fluid flow control technology, it requires a satisfactory operation and less maintenance.

in the pneumatic control system, pneumatic regulator output signal can be directly driven a diaphragm or piston actuator spring actuator, pneumatic valve action. In this case, the pneumatic valve position to determine the required energy is provided by the compressed air, compressed air shall be in outdoor equipment to dry, to prevent freezing, and purification and filtration.

when a pneumatic valve pneumatic control and electric regulator used, can be used in pneumatic valve positioner or electricity in converter. The compressed air supply system can be like for full pneumatic control system.

in regulating theory of terminology, regulating pneumatic valve both static characteristic, and the dynamic characteristics, thus it affects the success or failure of control circuit. Static characteristic or gain is pneumatic valve flow characteristic, it depends on the size of the pneumatic valve, pneumatic valve core and the combination of the pneumatic valve seat structure, type of actuator, pneumatic valve positioner, pneumatic valve before and after pneumatic valve pressure and fluid properties.

dynamic characteristics is performed by the actuators or pneumatic valve positioner a mechanism combination. For slower production process, such as temperature control or liquid level control, dynamic characteristics of pneumatic valve generally not the limiting factor in terms of controllability. For faster system, such as the flow of fluid control, regulating pneumatic valve may have obvious lag, to consider something in loop control.

the automatic regulating pneumatic valve history can be traced back to self-reliance type pressure regulating pneumatic valve, it includes a pneumatic valve with a weight bar form, the weight used to balance the pneumatic valve core, and adjust, another early on paper. it Wen is in the form of pressure balance type pressure regulating pneumatic valve. Process of pressure pipeline from spring film regulating pneumatic valve film chamber. Whether reduced pressure pneumatic valve, pneumatic valve pressure surge after pneumatic valve or the differential pressure regulating valve are pen enough from the change of the base type pneumatic valves.


pneumatic transducer and appearance of regulator, will naturally lead to pneumatic word throttle valve application. They are essentially reduced pressure pneumatic valve or pneumatic valve, pneumatic valve after pressure surge to instrument compressed air to replace the process fluid. Many in the production of reduced pressure pneumatic valve company has developed into regulating pneumatic valve manufacturer. Adjust the pneumatic valve from the aspects of quantity and complexity of the application of continuously development, many of the pneumatic valve pneumatic valve body and improvement of the attachment can be used to solve various problems.
