Introduce the structure and working principle of pneumatic valve 1

solenoid pneumatic valve including coil, magnets, plunger. When the coil current is switched on, the magnetism is produced, with magnets attract each other, the magnet will pull the plunger. Shut off the power, the magnet and the plunger is reset, this electromagnetic pneumatic valve can finish the work process. This is the working principle of pneumatic valve. Solenoid pneumatic valve is commonly used in the hydraulic system, to close and open the oil. In fact, according to the flow through the medium temperature, pressure, etc. , such as the pipeline pressure and their status without pressure. The working principle of electromagnetic pneumatic valve is different. For example in artesian condition need to zero pressure startup, is after electrify, the brake coil whole body sucked up. Pneumatic valve, pressure state of the electromagnetic coil is sucked out after the power supply plug in a pin on the lock body, with the top of the lock body and the pressure of fluid itself. The difference between these two approaches is that the state of the artesian solenoid pneumatic valve, because the coil to suck up the lock body, so the volume is larger and the electromagnetic air valve with the pressure, only need to suck up the pin, so the relatively small volume can be done.
