Ensure the optimization of pneumatic pneumatic control valve

Along with the advance of science and technology in our country, and promote the development of production automation in our country, the temperature, liquid level, pressure and flow rate of strict control, and is widely used in various industries. Pneumatic pneumatic control valve is to control the characteristics of simple, quick response, and intrinsically safe, do not need another explosion protection measures. In the process of pneumatic pneumatic control valve selection, installation, must be in strict accordance with the pneumatic pneumatic - valve requirements prescribed in the rules and regulations, and fully consider the working staff of pneumatic pneumatic - valve installation, choice of experience, to ensure the optimization of pneumatic pneumatic control valve selection. Otherwise, will affect the service life of pneumatic pneumatic control valve, causing unnecessary economic losses, and even cause automatic control circuit can not run normally, causing the occurrence of major accidents. A, use of pneumatic pneumatic control valve, pneumatic pneumatic - valve structure is A quarter-turn, it 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, characteristics: a quarter-turn structure, 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.
