Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valve cleaning, in particular to a novel electromagnetic valve with a self-cleaning function structure. Background Art

[0002] In the intelligent and automated pig farming industry, solenoid valves play an important role. In the automatic drinking water devices of pig farms, solenoid valves are used to control the water supply. In order to ensure that pigs in different areas can obtain stable water pressure, some large pig farms use solenoid valves in conjunction with pressure sensors.

[0003] Currently, this type of solenoid valve on the market is usually made by directly making the internal fluid channel of the solenoid valve into a tapered form. When the fluid enters the narrow channel from the wide channel, the speed of the fluid will gradually decrease and the pressure will gradually increase. This increase in speed and change in pressure will enhance the fluid's flushing effect on the inside of the solenoid valve, effectively removing impurities attached to the inside of the solenoid valve.

[0004] Currently, this type of solenoid valve on the market, although it speeds up the flow rate and increases the pressure to remove impurities inside the solenoid valve by changing the internal fluid channel of the solenoid valve to a tapered form, it is difficult to completely remove the viscous impurities mixed in the water after passing through the fluid, and the viscous impurities will pass through the damping hole to the inner cavity of the solenoid valve. If the user does not use it for a long time, the viscous impurities will accumulate and harden, causing the internal components of the solenoid valve to become stuck and blocked, making the solenoid valve unable to work normally. For this reason, we propose a new type of solenoid valve with a self-cleaning function structure to solve the above problems. Utility Model Content

[0005] In order to make up for the above deficiencies, the present invention provides a novel solenoid valve with a self-cleaning function structure, aiming to improve the problem in the prior art that viscous impurities retained in the inner cavity of the solenoid valve cannot be cleared.

[0010] The cleaning assembly further comprises a cylindrical spring, wherein the cylindrical spring is fixedly connected to the inner side of the valve core sleeve, and one end of the cylindrical spring is fixedly connected to the top end of the moving magnetic core;

[0011] As a further description of the above technical solution:

[0012] A valve cavity is formed on the inner side of the top of the valve body, a tower-shaped spring is fixedly connected to the inside of the valve cavity, and a diaphragm assembly is fixedly connected to one end of the tower-shaped spring;

[0024] 1.

By turning off the power supply, the moving magnetic core with the cleaning needle can quickly enter the water outlet under the elastic force of the cylindrical spring. The switching state of the solenoid valve causes the cleaning needle to move back and forth, and the viscous impurities mixed in the inner cavity of the solenoid valve will also be flushed and finally discharged from the water outlet, thereby automatically clearing the viscous impurities inside the solenoid valve.

[0025] 2. In the present invention, the liquid enters the valve cavity through the damping hole. When the electrical connecting rod is energized, the moving magnetic core moves upward with the magnetic core and the cleaning needle, causing the liquid inside the valve cavity to flow from the water outlet hole to the water outlet pipe, thereby realizing the flow of liquid inside the valve body.
