[0027] The utility model discloses a full closed electromagnetic bidirectional fluid hydraulic superhigh pressure reversing valve.

[0028] Embodiment 1

[0029] The utility model provides a full closed electromagnetic bidirectional fluid hydraulic superhigh pressure reversing valve as Figures 1-5 The utility model discloses a full closed electromagnetic bidirectional fluid hydraulic superhigh pressure reversing valve including valve body 1 and fixedly arranged electromagnetic controller 2 on the outer wall of valve body 1, the outer wall of valve body 1 is provided with multiple liquid outlets and liquid inlets, the inside of liquid outlet and liquid inlet is equipped with liquid guide pipe 3, and the outer wall both ends of multiple liquid guide pipes 3 are provided with connecting thread 11 and are threaded in the liquid outlet and liquid inlet, and the inside upper end of liquid guide pipe 3 is equipped with filter screen 4, and the inner wall lower end of liquid guide pipe 3 is fixedly equipped with horizontal plate 5, and the inside of horizontal plate 5 is provided with multiple filter holes 6, and the inner wall of filter hole 6 is fixedly embedded with one-way filter bag 7, and the lower end of one-way filter bag 7 is hot melt connected with the inner wall downside of filter hole 6, and one-way filter bag 7 is silica gel soft bag, and one end of one-way filter bag 7 is conical and is provided with flow hole 8, and the lower end of one-way filter bag 7 is equipped with sealing plate 9, and two symmetrically arranged support rods 10 are fixedly arranged between sealing plate 9 and horizontal plate 5.

[0030] When the reversing valve is running, the electromagnetic controller 2 drives the valve core inside the valve body 1 to move, causing the corresponding outlet and inlet to cooperate to complete the fluid flow. During the fluid flow, the fluid first enters the guide pipe 3 and cooperates with multiple one-way filter bags 7. At this time, the fluid passes through the flow holes 8 of the one-way filter bags 7 and enters between the horizontal plate 5 and the filter screen 4. The filter screen 4 filters the impurities inside the fluid. Then, the filtered fluid enters the valve body 1 for stable reversal, ensuring that the overall fluid is relatively clean and reduces fluid flow. This minimizes the impact on the internal components of the valve body 1. When the fluid flows bidirectionally from the filter screen 4 to the horizontal plate 5, the fluid carries impurities that push the one-way filter bag 7. Since one end of the one-way filter bag 7 is tapered, the impurities cannot enter the flow hole 8 and push the tapered end of the one-way filter bag 7, causing the one-way filter bag 7 to flip. At this time, the flow hole of the one-way filter bag 7 is blocked by the sealing plate 9, preventing the impurities from flowing out and allowing the liquid to flow outward through the contact gap. This ensures that the impurities are limited within the liquid guide tube 3 and cannot flow freely.

[0031] Example 2

[0032] Example 2, based on Example 1, aims to enable quick positioning and easy disassembly of filter 4, such as... Figures 3-4 As shown, limiting plates 12 are fixedly provided on both lower ends of the inner wall of the liquid guide tube 3. The filter screen 4 is provided on the surface of the limiting plate 12. An insertion limiting mechanism is provided between the top of the filter screen 4 and the inner wall of the liquid guide tube 3. The insertion limiting mechanism includes a plug 13. Two symmetrically arranged mounting plates 14 are fixedly provided on the top of the filter screen 4. A spring 15 is fixedly provided on the outer wall of the mounting plate 14, and a pull plate 16 is fixedly provided through the spring 15. The plug 13 is fixedly connected to the pull plate 16. The inner wall of the liquid guide tube 3 is provided with a slot 17 for the plug 13 to be inserted.

[0033] When installing the filter screen 4, first bring the two pull plates 16 close together so that the pull plates 16 drive the insert block 13 to move and squeeze the spring 15. Then, send the filter screen 4 into the liquid guide tube 3 and contact the limiting plate 12 to determine the setting position of the filter screen 4. Then release the pull plates 16. Under the elastic force of the spring 15, the pull plates 16 move back to their original position and push the insert block 13 into the slot 17, thereby completing the fixing of the filter screen 4.
