Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a valve anti-clogging structure is disclosed, including a first connecting pipe 1 and a second connecting pipe 2. A connecting plate 3 is fixed to one end of the first connecting pipe 1 near the second connecting pipe 2. A sleeve 4 is slidably connected to the surface of the second connecting pipe 2, and a connecting cover 5 is fixedly connected to one end of the sleeve 4 near the first connecting pipe 1. A side ring plate 6 is fixed to the side of the connecting cover 5 near the connecting plate 3. A filter screen 7 is provided inside the connecting cover 5. A driving assembly 9 for driving the connecting cover 5 to move is installed on the outer wall of the second connecting pipe 2. A plurality of connecting assemblies 10 for fixing the side ring plate 6 are provided on the side of the connecting plate 3.

[0024] Flanges are fixed at the ends of the first connecting pipe 1 and the second connecting pipe 2 that are far apart from each other.

[0025] In this embodiment, when installing the structure, the flange on the first connecting pipe 1 or the second connecting pipe 2 is connected to the flange on the valve inlet.

[0026] The drive assembly 9 includes a vertical plate 91 fixed to the outer wall of the second connecting pipe 2. A long screw 92 is threaded through the vertical plate 91 and rotatably connected to it. One end of the long screw 92 is rotatably connected to the outer wall of the connecting cover 5 via a bearing, and the other end of the long screw 92 is fixed with a handle 93.

[0027] By rotating the long screw 92 through the handle 93, the connecting cover 5 can be driven to move along the surface of the second connecting tube 2, thereby moving the sleeve 4 so that the connecting cover 5 can move closer to or further away from the connecting plate 3.

[0028] A guide rod 94 is slidably connected through the vertical plate 91, and one end of the guide rod 94 is fixedly connected to the connecting cover 5.

[0029] In this embodiment, the guide rod 94 can guide the movement of the connecting cover 5 and prevent the connecting cover 5 from rotating on the surface of the second connecting tube 2.

[0030] A support ring 8 is fixed to the inner wall of the connecting cover 5, and the filter screen 7 is located between the support ring 8 and the connecting plate 3.

[0031] When the connecting cover 5 is in contact with the connecting plate 3, the support ring 8 will press and fix the filter screen 7.

[0032] The inner wall of the sleeve 4 is provided with multiple annular grooves 41, and each annular groove 41 is fitted with a sealing ring 42.

[0033] The sealing ring 42 can increase the sealing between the sleeve 4 and the surface of the second connecting pipe 2.

[0034] The connecting assembly 10 includes a fixing ring 101 fixed to the side surface of the connecting plate 3, and the fixing ring 101 is located on the side away from the side ring plate 6. A sliding rod 102 is slidably connected inside the fixing ring 101. An L-shaped plate 103 is fixedly connected to the end of the sliding rod 102 away from the first connecting pipe 1. A pressing bolt 104 is threaded through the side wall of the L-shaped plate 103 and rotatedly connected by a thread. The pressing bolt 104 is in contact with the surface of the side ring plate 6.

[0035] The slide bar 102 can slide along the inside of the fixed ring 101, so that the L-shaped plate 103 can follow the slide bar 102 to approach or move away from the side ring plate 6. When the vertical part of the L-shaped plate 103 coincides with the side ring plate 6, the side ring plate 6 is squeezed by rotating the compression bolt 104, thus realizing the fixed connection between the connecting plate 3 and the side ring plate 6.

[0036] Working principle: During use, the flange on the second connecting pipe 2 is connected to the flange on the valve inlet with bolts, and the flange on the first connecting pipe 1 is connected to the pipeline conveying liquid. The liquid passes through the filter screen 7 before the valve, which can intercept impurities in the liquid, thereby preventing impurities from clogging the valve. When it is necessary to disassemble, clean or replace the filter screen 7, first loosen the clamping bolts 104 on each connecting component 10, then pull the L-shaped plate 103 to separate from the side ring plate 6, and then rotate the long screw 92 through the handle 93. The long screw 92 will drive the connecting cover 5 and the side ring plate 6 to separate from the connecting plate 3, so that the filter screen 7 inside the connecting cover 5 can be taken out for replacement or cleaning. After cleaning, put the filter screen 7 back into the connecting cover 5, and then rotate the handle 93 in the opposite direction to make the connecting cover 5 and the side ring plate 6 fit with the connecting plate 3. Then move the L-shaped plate 103 to overlap with the side ring plate 6, and then rotate the clamping bolts 104 to squeeze the side ring plate 6 to complete the reassembly.
