The four-way solenoid valve is a kind of solenoid valve, which is widely used in our daily production. If you want to understand the four-way solenoid valve, you must first understand the working principle of the four-way solenoid valve:
In the system, whenever a current passes through the coil, an excitation effect will occur, so that the fixed iron core attracts the moving iron core, and the moving iron core drives the spool valve core and compresses the spring, changing the position of the spool valve core, thus changing the position of the spool valve core. The direction of the fluid. And when the coil loses current, the spool valve core is pushed by the elastic force of the spring, and the iron core is pushed back to make the fluid flow in the original direction. It is more common in daily production that in our oxygen production, the switch of the forced valve of the molecular sieve switching system is controlled by a two-position four-way solenoid valve, and the airflow is respectively supplied to both ends of the piston of the forced valve. To control the opening and closing of the forced valve.
The above is the working principle of the four-way solenoid valve, I hope to help friends in need.
