Pneumatic pneumatic - valve to realize the switch quantity or proportion type adjustment

Pneumatic pneumatic - valve to realize the switch quantity or proportion type adjustment, industrial automation control system control reception to complete adjustment pipeline medium: flow, pressure, temperature, liquid level and other process parameters. Pneumatic pneumatic regulator is compressed gas as the source of power, cylinder as actuator, and with the aid of the valve positioner, converters, solenoid valve, valve, gas storage, gas filter accessories to drive the valve. Pneumatic pneumatic control valve is to control the characteristics of simple, quick response, and intrinsically safe, do not need another explosion protection measures. Pneumatic pneumatic regulator features: the USES and features of A pneumatic valve, pneumatic purpose is A quarter-turn structure, it has to do with the valve positioner, proportional control can be realized; V valve core is the most suitable for all kinds of regulating occasions, with large rated flow coefficient, adjustable than large, good sealing effect, sensitive regulation performance, small size, can be installed in vertical lie. Apply to control gas, steam, liquid medium. B, features: pneumatic pneumatic - valve structure is a quarter-turn, by the v-shaped body, actuator, positioner, and other accessories; There is a best than the intrinsic flow feature of such as approximation; With double bearing structure, small starting torque, has excellent sensitivity and speed of induction; Strong ability of shear. C, pneumatic piston actuators using compressed air as power source, through the movement of the piston driven 90 - degree rotating crank arm, to make the automatic opening and closing of the valve. Part of it is: the adjusting bolt, actuator housing, crank arm shaft, piston, connecting rod, cylinder block, cylinder, cardan shaft. D, pneumatic working principle of pneumatic control valve, pneumatic control valve consists of actuators and regulating mechanism. Is a thrust part of the pneumatic control valve actuator, it according to the size of the control signal pressure to produce the corresponding thrust, promote regulating mechanism. Body is pneumatic pneumatic - valve regulating unit, it directly contact with the control agent, regulating the flow of the fluid.
