Function, working principle and structure of water solenoid valve

[ad_1]

Function, working principle and structure of water solenoid valveWhat are the characteristics? How does the water solenoid valve work? How does it work? Let’s look at the analysis brought by the small valve below:
Solenoid valve for water is a kind of solenoid valve. There is a closed cavity, and there are through holes in different positions, and each hole is connected to a different oil pipe. In the middle of the cavity is a valve, and two electromagnets are on both sides. Which side of the magnet coil on both sides is energized, the valve body is attracted to On the other hand, by controlling the movement of the valve body to block or leak different oil discharge holes, while the oil inlet hole is normally open, the hydraulic oil will enter different oil discharge pipes, and then push the piston of the cylinder through the pressure of the oil, The piston drives the piston rod again, and the piston rod drives the mechanical device to move. In this way, the mechanical movement is controlled by controlling the electric current of the electromagnet.

Function, working principle and structure of water solenoid valve

The solenoid valve for water is connected with the first opening valve and the second opening valve. The main valve and the pilot valve step by step make the electromagnetic force and pressure difference directly open the main valve port. When the coil is energized, electromagnetic force is generated to make the moving iron core and the static iron core close together, the pilot valve port is opened and the pilot valve port is set on the main valve port, and the moving iron core is connected with the main valve core. The pressure in the cavity is unloaded through the pilot valve port, and under the simultaneous action of pressure difference and electromagnetic force, the main valve core moves upwards to open the main valve for medium circulation. When the coil is powered off, the electromagnetic force disappears. At this time, the moving iron core closes the pilot valve hole under the action of its own weight and spring force. At this time, the medium enters the upper cavity of the main valve core in the balance hole to increase the pressure of the upper cavity. At this time The main valve is closed under the action of spring return and pressure, and the medium is cut off. The structure is reasonable, the action is reliable, and the work is also reliable when there is zero pressure difference.

Function, working principle and structure of water solenoid valve

The above content is the function, working principle and structure of the water solenoid valve brought by the small valve today. Combined with the structure diagram of the water solenoid valve above, I believe that everyone has a lot of knowledge about the function, working principle and structure of the water solenoid valve. Good understanding~
