[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media.

[0003] Existing valves generally prevent valve clogging by placing filter plates. After long-term use, dirt will accumulate on the filter plates. In order to ensure the normal use of the valve, the filter plates need to be replaced. However, existing valves are generally connected to pipes through threaded connections. When replacing the filter plates, the valve needs to be removed from the pipe and then the filter plates inside the valve need to be replaced. The filter plate replacement efficiency is low.

[0004] Therefore, we propose an anti-clogging valve to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: an anti-clogging valve, comprising a valve body 1, a spring 6, a filter plate 8 and a water outlet 12, a mounting groove 4 is provided inside the valve body 1, and a filter plate 8 is arranged inside the mounting groove 4, a valve core 9 is provided inside the valve body 1, and a through port 901 is provided in the middle of the valve core 9, a valve stem 10 is fixed to the top of the valve core 9, and a handle 11 is fixed to the top of the valve stem 10, an empty groove 5 is provided at the bottom of the mounting groove 4, a spring 6 is arranged inside the empty groove 5, a water outlet 12 is provided inside the valve body 1, a notch 102 is provided on the surface of the valve body 1, and a filling plate 2 is provided inside the notch 102.

[0024] The right end of the filling plate 2 is connected to the valve body 1, and the filling plate 2 and the valve body 1 are movably connected. The notch 102 is located at the top of the mounting groove 4. The top of the filling plate 2 is arc-shaped and fits the surface of the valve body 1, so that the filling plate 2 can be opened and closed on the valve body 1, which is convenient for replacing the filter plate 8.

[0025] A second protrusion 201 is provided at the left end of the filling plate 2, and a first protrusion 101 is provided on the surface of the valve body 1 at a position corresponding to the second protrusion 201, the first protrusion 101 and the second protrusion 201 are penetrated by a bolt 3, the bolt 3 is threadedly connected to the first protrusion 101, and the bolt 3 and the second protrusion 201 are movably connected, a limiting ring 301 is fixed in the middle of the bolt 3, a rubber plate is provided at the bottom of the filling plate 2, and the filling plate 2 forms a fixed structure with the valve body 1 through the bolt 3, so that the filling plate 2 and the valve body 1 can be fixed by the bolt 3, so that the filter plate 8 can be fixed inside the valve body 1 and the sealing inside the valve body 1 can be ensured.

[0026] The bottom of the spring 6 is fixed to the bottom of the empty slot 5, and a lifting plate 7 is fixed to the top of the spring 6. The size of the lifting plate 7 is consistent with the opening size of the empty slot 5. The filter plate 8 is slidably connected to the mounting slot 4. The filter plate 8 in the valve body 1 can be lifted up by the lifting plate 7, which facilitates the removal of the filter plate 8 from the valve body 1.

[0027] The water outlet 12 passes through the middle of the valve body 1 , and the filter plate 8 is located inside the water outlet 12 , so that water can flow through the filter plate 8 , thereby facilitating filtering of the water passing through the valve body 1 .

The water pipe can be connected to the two ends of the valve body 1 through the threaded connection ports. The size of the water flow through the water outlet 12 is controlled by the rotation angle of the valve core 9 in the valve body 1, which is convenient for controlling the size of the water flow.

[0029] Working principle: When using the anti-clogging valve, first connect the two ends of the valve body 1 to the water pipe, then rotate the handle 11 to 90°, and at the same time drive the valve core 9 to rotate through the valve stem 10, so that the through port 901 is connected with the water outlet 12, so that the water flows through the filter plate 8, and the water flows through the water outlet 12 and the through port 901 to reach the water pipe at the other end of the valve body 1, thus completing the use of the anti-clogging valve.

[0030] After the anti-clogging valve has been used for a long time, the filtering efficiency of the filter plate 8 is reduced, thereby affecting the normal use of the valve. When the filter plate 8 needs to be replaced, the handle 11 is first rotated to make the valve stem 10 drive the valve core 9 to rotate, disconnecting the water outlet 12 from the through port 901, and preventing water from flowing from the right end of the valve body 1 to the left end, and then the bolt 3 is rotated to make the bolt 3 move upward in the second protrusion 201 and leave the first protrusion 101, and then the filling plate 2 inside the gap 102 is opened, and at the same time, the spring 6 in the empty groove 5 rebounds to make the lifting plate 7 rise and lift the filter plate 8, then take out the filter plate 8 and replace it, and then close the filling plate 2, rotate the bolt 3, make the bolt 3 enter the first protrusion 101, so that the filling plate 2 is fixed on the valve body 1, and finally rotate the handle 11 to connect the through port 901 with the water outlet 12, thus completing the replacement of the filter plate 8 of the anti-clogging valve, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
