[0002] A solenoid valve is a device that controls the flow of fluids. It uses electromagnetic force to control the opening and closing of valves. Solenoid valves are usually composed of an electromagnet (coil), a valve body, a valve core, and a valve. When the electromagnet is energized, the magnetic field generated will attract or push the valve core, thereby changing the state of the valve, allowing the fluid to flow or blocking the flow. Solenoid valves are widely used in industrial automation systems, hydraulic systems, water supply systems, air conditioning systems, and other fields to control the flow direction, pressure, and flow of fluids such as gases and liquids.

[0049] The electromagnetic assembly includes a moving iron core 20, a sliding groove 22 is opened between the junction box 8 and the fixed seat 10, the bottom of the fixed seat 10 is located at the sliding groove 22 and is fixedly connected with a sleeve 23, the moving iron core 20 is slidably connected to the sliding groove 22, and a first spring 19 is arranged between the top of the moving iron core 20 and the top of the sliding groove 22, a coil 18 is arranged around the sliding groove 22 inside the junction box 8, and a sealing block 11 is fixedly connected to the bottom of the moving iron core 20, and a first groove 21 is opened on the right side of the sealing block 11.

[0060] A plurality of bolt mounting holes are provided on the flange 7 to facilitate the installation of the flange 7 .

[0061] Working principle: The liquid level electromagnetic control valve inputs liquid through the input port 25. When the coil 18 is energized, a magnetic field is generated, which pushes the moving iron core 20 to slide upward in the sliding groove 22, so that the sealing plug 11 slides upward, releasing the seal of the input port 25 and the output port 16. After the coil 18 is powered off, the sealing plug 11 slides downward under the action of the first spring 19, thereby sealing the connection between the input port 25 and the slot 24. In the process of pressing the sealing plug 11 downward, the liquid in the slot 24 flows to the output port 16 through the first groove 21, thereby realizing the connection between the input port 25 and the output port 16, by setting the input type liquid level meter 6 to measure the liquid level of the liquid inside the tank body 1, and under the control and regulation of the controller 2, when the liquid level inside the tank body 1 is too low, the liquid is input by opening the electromagnetic control valve, and when the liquid level inside the tank body 1 reaches a predetermined value, the electromagnetic control valve is closed, so that the electromagnetic control valve automatically adjusts the liquid level. The junction box 8 of the electromagnetic control valve is fixedly installed with the electromagnetic control valve body 5, and the fixing rod 14 is first inserted into the front side of the fixing box 9 and then inserted into the jack 17 on the fixing seat 10, and the fixing rod 14 is inserted into the fixing box 9. After the square block 45 at the rear end passes through the square groove 13, the fixing rod 14 is rotated so that the square block 45 is no longer aligned with the square groove 13 in the circular groove 46, so that the fixing seat 10 and the fixing box 9 are fixed, and the top plate 31 is lifted by the second spring 32, and the top plate 31 lifts the fixing seat 10, so that the annular groove 29 on the fixing rod 14 abuts against the protrusion 30 on the bottom side of the inner wall of the jack 17, so that the fixed installation between the fixing seat 10 and the fixing box 9 is more stable. When it is necessary to disassemble, it is only necessary to press down the junction box 8, and then rotate the fixing rod 14 so that the square block 45 and the square groove 13 is aligned, and then the fixing rod 14 is pulled out through the pull ring 15 to complete the disassembly, which solves the problem that the electromagnetic control valve is not convenient and time-consuming and labor-intensive to maintain and disassemble. When the internal pressure of the pipeline is too high, the water pressure pushes the sealing block 40, so that the input port 25 and the output port 16 are connected through the pressure relief groove 28 and the slot 24. When the pressure decreases, the sealing block 40 is pushed to the connection between the installation groove 27 and the input port 25 under the action of the telescopic rod 36 and the third spring 37, thereby closing the connection between the input port 25 and the output port 16 to avoid excessive pressure inside the pipeline to damage the equipment.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
