[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-7 As shown in the figure, this embodiment provides a solenoid valve for easy maintenance and repair of a diaphragm filter press, including multiple pipelines 1, with a solenoid valve body 2 arranged between the multiple pipelines 1. The solenoid valve body 2 is provided with a disassembly and assembly structure 3, which includes telescopic flexible cylinders 4 symmetrically fixedly installed at both ends of the solenoid valve body 2. A sleeve 5 is fixedly installed at one end of the telescopic flexible cylinder 4, and a fixing frame 6 is fixedly installed on the surface of the sleeve 5. A rotating rod 7 is movably installed on one side of the fixing frame 6, and two screws 8 are symmetrically and movably installed inside the fixing frame 6. The rotating rod 7 and the screws 8 are fixed at their closest ends. The solenoid valve body 2 is fixedly installed on the pipeline 1 by means of meshing gears 9 and moving blocks 10 on the screw 8. One end of the moving blocks 10 is fixedly installed with a clamping frame 11. Through the setting of the disassembly and assembly structure 3, the solenoid valve body 2 is fixedly installed on the pipeline 1 by means of the docking of multiple sleeves 5 and the clamping and fixing of multiple clamping frames 11. This replaces the traditional fixing method of bolts and flanges to fix the pipeline 1 and the solenoid valve body 2. It saves cumbersome operation steps during maintenance and disassembly, and also avoids the problem of water stain corrosion and rust, thus making it convenient to disassemble, inspect and maintain the solenoid valve.

[0025] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, multiple support rods 12 are symmetrically fixedly installed on the surface of the solenoid valve body 2, and multiple support frames 13 are symmetrically fixedly installed on the surface of the sleeve 5. The support frame 13 has a groove 14 inside. A spring 15 connected to the inner wall of the groove 14 is fixedly installed on the top of the support rod 12. Two slide rods 16 are symmetrically fixedly installed on the inner wall of the groove 14. Slide grooves 17 are opened on both sides of the support rod 12. A first toothed sleeve 18 is fixedly installed on the side of the two clamping frames 11 that are close to each other. A second toothed sleeve 19 is fixedly installed on the surface of the pipeline 1. With the support rod 12, support frame 13, groove 14, and spring 15, the solenoid valve body 2 is positioned between the two pipes 1, and the sleeve 5 is fitted onto the pipe 1. At this time, the sleeve 5, supported by the support rod 12 and elastically pushed by the spring 15, can be securely fitted onto the pipe 1, thus providing positioning support for the solenoid valve body 2 under the action of elastic support. This prevents the solenoid valve body 2 from shaking and falling off when the transmission clamping frame 11 clamps and fixes the pipe 1. With the sliding rod 16 and sliding groove 17, when the solenoid valve body 2 is on the pipe 1, the support frame 13... It moves on the support rod 12, and the sliding connection of the slide rod 16 and the slide groove 17 can reduce the friction between the support frame 13 and the support rod 12, thereby reducing the resistance and allowing the spring 15 to push the sleeve 5 better. With the setting of the first toothed sleeve 18 and the second toothed sleeve 19, when the two clamping frames 11 are clamped on the pipeline 1, the first toothed sleeve 18 on the inner wall of the clamping frame 11 meshes with the second toothed sleeve 19 on the surface of the pipeline 1, further improving the tightness and firmness between the clamping frame 11 and the pipeline 1, making the installation and fixation of the solenoid valve body 2 more stable.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, two support plates 20 are symmetrically and movably installed on one end of the rotating rod 7. A magnetic block 21 is fixedly installed on one end of the support plate 20. A magnetic ring 22 is fixedly installed on the surface of the fixed frame 6. A sealing groove 23 is opened inside the sleeve 5. A sealing strip 24 is fixedly installed on one end of the pipeline 1. Multiple viewing windows 25 are installed on the solenoid valve body 2. Multiple cover plates 26 are movably installed on the surface of the solenoid valve body 2. Multiple viewing windows 25 and multiple cover plates 26 are symmetrically distributed on the solenoid valve body 2. A first connecting block 27 is fixedly installed on both sides of the solenoid valve body 2. A second connecting block 28 is fixedly installed on one side of the cover plate 26. By using the support plate 20, magnetic block 21, and magnetic ring 22, the clamping frame 11 is clamped and fixed on the pipeline 1. Rotating the support plate 20 causes the magnetic block 21 to engage with the magnetic ring 22. The magnetic block 21 and magnetic ring 22 adhere and attract the rotating rod 7, preventing it from rotating due to collision and causing the clamping frame 11 to loosen. During disassembly, rotating the support plate 20 allows the magnetic block 21 to detach from the magnetic ring 22. The flattened support plate 20 also facilitates the rotation of the rotating rod 7. The sealing groove 23 and sealing strip 24 provide sealing for the pipeline 1 and... The connection of the sleeve 5 is sealed to prevent material leakage. With the setting of viewing window 25, cover plate 26, first connecting block 27 and second connecting block 28, two viewing windows 25 are symmetrically set on the solenoid valve body 2 to facilitate the inspection of the inside of the solenoid valve body 2, so as to detect the fault of the solenoid valve body 2 in time and facilitate its disassembly and maintenance. The cover plate 26 can protect the viewing window 25 from collision damage. At the same time, the first connecting block 27 and the second connecting block 28 form a riveting to fix the cover plate 26 and prevent it from loosening.

[0027] In this embodiment, as Figures 1-7 As shown in the figure, the working process of a solenoid valve for easy maintenance and repair in a diaphragm filter press provided in this embodiment is as follows:

[0028] When installing the solenoid valve body 2, insert the solenoid valve body 2 between the two pipes 1, so that the sleeves 5 at both ends of the solenoid valve body 2 are tightly fitted onto the pipes 1 under the support of multiple support rods 12 and support frames 13. Then, rotate the rotating rod 7 to drive the two screws 8 to rotate through the meshing gear 9, so that the two screws 8 drive the two moving blocks 10 to move closer to each other, so that the clamping frame 11 clamps onto the pipes 1 to install and fix the solenoid valve body 2. When disassembling for maintenance, rotate the rotating rod 7 in the opposite direction to separate the two clamping frames 11 from the pipes 1, and then pull the two sleeves 5 to retract and detach from the pipes 1, so that the solenoid valve body 2 can be completely disassembled from the pipes 1 for maintenance.

[0029] In summary, in this embodiment, a solenoid valve for easy maintenance and repair in a diaphragm filter press is provided. Through the arrangement of the support rod 12, support frame 13, groove 14, and spring 15, the solenoid valve body 2 is positioned between two pipelines 1, and the sleeve 5 is fitted onto the pipeline 1. At this time, the sleeve 5, supported by the support rod 12 and elastically pushed by the spring 15, can be securely fitted onto the pipeline 1. Thus, under the action of elastic support, the solenoid valve body 2 is positioned and supported, preventing the solenoid valve body 2 from shaking and falling off when the transmission clamping frame 11 clamps and fixes the pipeline 1. The arrangement of rod 16 and slide groove 17 allows the support frame 13 to move on the support rod 12 when the solenoid valve body 2 is on the pipeline 1. The sliding connection between the slide rod 16 and slide groove 17 reduces the friction between the support frame 13 and the support rod 12, thereby reducing resistance and allowing the spring 15 to better push the sleeve 5. The arrangement of the first toothed sleeve 18 and the second toothed sleeve 19 allows the first toothed sleeve 18 on the inner wall of the clamping frame 11 to mesh with the second toothed sleeve 19 on the surface of the pipeline 1 when the two clamping frames 11 are clamped on the pipeline 1, further improving the clamping frame 11 and the pipeline 1. The tightness and firmness of the connection make the installation and fixation of the solenoid valve body 2 more stable. Through the arrangement of the support plate 20, magnetic block 21, and magnetic ring 22, after the clamping frame 11 is clamped and fixed on the pipeline 1, rotating the support plate 20 causes the magnetic block 21 and magnetic ring 22 to adhere. The magnetic block 21 and magnetic ring 22 adhere and attract, thus fixing the rotating rod 7 and preventing rotation due to collision, which could cause the clamping frame 11 to loosen. During disassembly, rotating the support plate 20 allows the magnetic block 21 to detach from the magnetic ring 22. The flattened support plate 20 also facilitates the rotation operation of the rotating rod 7. Through the sealing groove 23 and sealing... The design of strip 24 can seal the connection between pipe 1 and sleeve 5 to prevent material leakage. The symmetrical arrangement of two viewing windows 25 on the solenoid valve body 2 through the viewing window 25, cover plate 26, first connecting block 27 and second connecting block 28 facilitates the inspection of the inside of the solenoid valve body 2, so as to detect faults in the solenoid valve body 2 in time and facilitate disassembly and maintenance. The cover plate 26 can protect the viewing window 25 from collision damage. At the same time, the first connecting block 27 and the second connecting block 28 form a riveting, which can fix the cover plate 26 and prevent it from loosening.

[0030] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
