Pneumatic valve accessories types and selection of
in the process of using pneumatic valve, usually need to configure some auxiliary parts to improve the performance of the pneumatic valve, or raise the use efficiency of pneumatic valve. Pneumatic valve common accessories include: air filter, the reversing solenoid valves, limit switches, electrical locator, etc. Pneumatic technology, air filter, pressure reducing valve, oil mist device together three air processing elements, is called a pneumatic triple a, to entering the air purification filter and decompression of the pneumatic instrument to instrument rated supply air pressure, the function of the equivalent circuit of power transformer.
pneumatic valve accessories categories:
double-acting pneumatic actuators: to control the valve opening and closing of the two type. （ Dual role)
spring return type actuator, pneumatic cutting off or malfunction, the circuit valve opened or closed automatically. （ Single-acting)
single electrical solenoid valve: valve opened or closed when power supply, power valve closed or opened ( Can provide explosion-proof type) 。
double electric solenoid valve: a coil electric valve open, another coil electric valve shut, with memory function ( Can provide explosion-proof type) 。
limit switch back to dispatch: valve switch position signal (teleportation Explosion-proof type) 。
electrical locator: according to the current signal ( Standard 4 - 20mA) The size of the control of media flow control valve ( Explosion-proof type) 。
pneumatic positioner: according to the pressure signal, The 0. 02 - 0. 1MPa) The size of the control medium flow control valve.
electrical converter: convert current signals into pressure signals, with pneumatic positioner ( Explosion-proof type) 。
air handling sanlian pieces: including air pressure reducing valve, filter, oil mist device, the gas source voltage lubrication, cleaning, moving parts.
manual operating mechanism: automatic control in abnormal situation can be manual operation.
pneumatic valve accessories selection:
pneumatic valve is complex automation control instrument, is composed of a variety of pneumatic components, the user should be accordance with the requirements of control in detail.
1, the pneumatic actuators: (1) double acting type, (2) single acting, (3) the action time of the specifications, (4).
2, electromagnetic valve: (1) single control double control electromagnetic valve, electromagnetic valve, (2) (3) using voltage, (4) explosion-proof type.
3, signal feedback: (1) mechanical switch, (2) the proximity switch, end output current signal, (4) using voltage, (5) explosion-proof type.
4, locator: 1) electrical locator, 2) pneumatic positioner, end up current signal, (4), (5) electrical converter, 6 explosion-proof pressure signal type.
5, air source treatment sanlian pieces: (1) filtering pressure reducing valve, (2) the oil mist.
6, manual operating mechanism.
