Air compressor solenoid valve core material

The core material of the air compressor solenoid valve core is controlled by a solenoid coil to change the direction of the fluid flow, or to cut off or switch on the air supply.
Commonly used four-way electromagnetic valve core material of the electromagnetic components from the fixed core, moving iron core, coil and other components. The valve body consists of a spool. Body, slide valve cover, spring base and other components.
The working principle of the four-way solenoid valve core material is shown in Figure 123a. When a current passes through the coil, excitation occurs, the fixed core attracts the moving core, the moving core drives the slide valve core and compresses the spring, which changes the position of the slide valve core, thereby changing the direction of the fluid. When the coil is de-energized, the slide valve core is pushed by the elastic force of the spring, and the core is moved back to move the fluid in the original direction. This solenoid valve core material can be used to force the valve switch in the switching system.
The working principle of the three-way solenoid valve core material is shown in Figure 123b. It can be used to switch on or off the air supply to switch the pneumatic control membrane head. It consists of valve body, valve cover, electromagnetic assembly, spring and sealing structure and other components. The seal block at the bottom of the moving iron core closes the inlet of the valve body by the pressure of the spring. After the power is turned on, the electromagnet pulls in, and the seal block with the spring on the upper part of the moving iron core closes the air outlet, and the air flow enters the membrane head from the air inlet to play a control role. When the power is lost, the electromagnetic force disappears, the moving iron core leaves the fixed iron core under the action of the spring force, moves downwards, opens the exhaust port, blocks the air inlet, and the film head air discharges through the exhaust port, and the diaphragm recovers. Original location. The three-way solenoid valve iron core material can be used in the emergency cut-off of the diaphragm expansion valve inlet valve control and brake fan emergency load control.
The working medium of the air core material of the air compressor solenoid valve is filtered clean compressed air, and the working pressure is 0.3-0.5 MPa.
