Free-standing pneumatic valve working principle and characteristics of the adjustment

self regulating pneumatic valve is divided into self-reliance type pressure, differential pressure and flow control three series pneumatic valves, pneumatic valve cock pneumatic valve, pneumatic valve adjustment and hydrophobic pneumatic valve, vacuum pneumatic valve, hydraulic pneumatic control valve, filter. Self-reliance type pressure regulating pneumatic valve pneumatic valve based on pressure point location points before and after pneumatic valve, pressure points in front of the pneumatic valve, pneumatic valve is used to regulate pressure constant before; Pressure points after pneumatic valve, pneumatic valve is used to adjust the pressure constant. When the pneumatic valve before and after pneumatic valve pressure at the same time on both sides of the chamber of the actuator is introduced, self-reliance type differential pressure regulating pneumatic valve can adjust at the ends of the pneumatic valve pressure constant, also can be installed on the pipe orifice differential pressure at the ends of the introduction of thin film on both sides of the chamber of the actuator, pneumatic valve, self-reliance type flow regulation or in other ways will flow detection with self-reliance type differential pressure pneumatic valve adjustment after implementation flow control.
rely on pneumatic valve within the medium flows through their own pressure, temperature, as energy drive pneumatic valve work automatically, do not need the power converter and secondary instrument. Type of this kind of self regulating pneumatic valve use pneumatic valve the output feedback signal, Pressure, differential pressure, temperature) Tube through the signal to the actuator driven by pneumatic valve pneumatic valve opening change, achieve the purpose of regulating pressure, flow, temperature.

regulating pneumatic valve is divided into direct effect and indirect effect type two kinds. Direct action type is also known as the spring load type, its have elastic element structure: such as spring, bellows, bellows type of bulb, etc. , the principle of balance with the elastic force feedback signal. Indirectly regulating pneumatic valve type, add a command ( The forerunner of pneumatic valve) It play a role of feedback signal amplification and then through the actuator, drive the pneumatic valve pneumatic disc movement to change the purpose of the pneumatic valve opening.
