Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve technology, specifically relating to a self-holding, high-efficiency, and energy-saving electromagnetic valve. Background Technology

[0002] A solenoid valve is a valve component that uses electromagnetic force to control the flow of fluid or change its direction. It is widely used in the field of automation control. Its core principle is to generate a magnetic field by energizing an electromagnetic coil, which drives the valve core to move to open or close the fluid passage. Energy costs can be saved by making energy-saving adjustments to the solenoid valve.

[0003] For example, in the Chinese utility model with announcement number CN203948748U and titled "A Novel Electromagnetic Valve Filter Clip", although the electromagnetic valve is filtered by an arched filter clip, the filter requires tools to disassemble, making disassembly troublesome and inconvenient for replacement. Utility Model Content

[0004] The purpose of this utility model is to provide a self-holding, high-efficiency, and energy-saving solenoid valve with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A self-holding high-efficiency energy-saving solenoid valve includes a valve body, a valve cover mounted on the upper surface of the valve body, a junction box fixedly connected to the upper surface of the valve cover, and a filter screen threadedly connected to the input end of the valve body.

[0007] As a further optimization of this utility model, the valve body input end is provided with several positioning holes, and the input end flange is connected to a first feed pipe.

[0008] As a further optimization of this utility model, a second feed pipe is fixedly connected to the top end of the first feed pipe, and a plurality of positioning rods located outside the second feed pipe are fixedly connected to the top end of the first feed pipe, wherein the positioning rods are inserted into positioning holes.

[0009] As a further optimization of this utility model, the upper surface of the junction box is provided with several wiring holes.

[0010] As a further optimization of this utility model, a signal feedback device is electrically connected to the upper surface of the junction box.

[0011] As a further optimization of this utility model, the valve body output end flange is connected to a discharge pipe.

[0012] The beneficial effects of this utility model are as follows: This utility model filters the material through a filter screen, intercepting tiny particles such as iron filings and dust in the fluid, preventing these impurities from entering the valve core or clogging the pipe, thus ensuring the normal operation of the solenoid valve. Then, the first and second feed pipes are positioned by the cooperation of the positioning hole and the positioning rod, avoiding leakage during feeding and preventing waste of resources.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1

[0019] like Figure 1 , Figure 2 and Figure 3As shown, a self-holding, high-efficiency, energy-saving solenoid valve includes a valve body 5, which provides a fluid passage. The valve body 5 has internal through-holes or channels through which fluid flows in a directional manner. A valve cover 4 is mounted on the upper surface of the valve body 5. The valve cover 4 and the valve body 5 together form a sealed pressure-bearing cavity to prevent fluid leakage. In high-pressure working environments, the sealing performance of the valve cover 4 directly affects the safety and reliability of the valve. A junction box 2 is fixedly connected to the upper surface of the valve cover 4. Several wiring holes 3 are provided on the upper surface of the junction box 2. The junction box 2 centrally manages the power supply and control circuit of the solenoid valve and provides a safe and reliable external wire connection port for the solenoid valve. In this design, there are two wiring holes 3, but the specific number can be changed according to actual conditions. The wiring holes 3 facilitate the connection of the wires (not shown in the figure) inside the junction box 2 to an external power source. A signal feedback device 1 is electrically connected to the upper surface of the junction box 2. By providing real-time feedback on the valve's open or closed status, remote automated control and monitoring are achieved, ensuring equipment operation. The valve body 5 has a status visualization feature. A filter screen 6 is threadedly connected to the input end of the valve body 5. The filter screen 6 prevents solid impurities from entering the solenoid valve, avoiding impurities from jamming the valve core and preventing the valve from closing or opening properly, thus extending the service life of the solenoid valve. The input end of the valve body 5 has several positioning holes 7. A first feed pipe 8 is connected to the input end flange. A second feed pipe 9 is fixedly connected to the top of the first feed pipe 8. Several positioning rods 10 are fixedly connected to the top of the first feed pipe 8, located outside the second feed pipe 9. The positioning rods 10 are inserted into the positioning holes 7, and the position of the first feed pipe 8 is fixed by the cooperation of the positioning holes 7 and the positioning rods 10. Material is then conveyed through the first feed pipe 8. The second feed pipe 9 is located at the top of the first feed pipe 8 and fits against the input end of the valve body 5. The dimensions of the first feed pipe 8 and the second feed pipe 9 decrease in a stepped manner to facilitate subsequent material conveying. The output end flange of the valve body 5 is connected to a discharge pipe 11, which facilitates material conveying and subsequent use.

[0020] It should be noted that this self-holding high-efficiency energy-saving solenoid valve requires the operator to install a filter screen 6 at the input end of the valve cover 4 during use. Then, the first feed pipe 8 is fixedly connected to the input end via a flange connection. The entire system is then energized via wires (not shown in the figure) and a power supply (not shown in the figure) in the junction box 2. The electromagnetic coil (not shown in the figure) inside the valve cover 4 generates a magnetic field that attracts the valve core (not shown in the figure), opening the channel. When the channel is open, the material is filtered through the filter screen 6. The material is then conveyed through the output end and the discharge pipe 11. When not in use, a power-off operation is performed, and a spring (not shown in the figure) rebounds the valve core to close the channel. When the solenoid valve is working, the signal feedback device 1 checks whether the valve action is normal to avoid incorrect commands.

[0021] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
