Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing valve filtration, in particular to a pressure reducing valve. Background Art

[0002] The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through regulation and automatically maintains a stable outlet pressure by relying on the energy of the medium itself.

[0003] The existing Chinese patent with publication number CN219413644U discloses a filtering structure of a pressure reducing valve. When in use, a filter plate is provided to filter the liquid flowing inside the pressure reducing valve. The fixing nut and the limiting ring can facilitate the installation and disassembly between the fixing clamp and the third fixing ring, and facilitate the detachment of the second fixing frame that provides support and fixing effect on both sides of the internal filter plate, so as to facilitate the replacement of the filter plate. However, when the filter plate needs to be replaced, whether it is installation or disassembly, it is necessary to separate it from the connected pipe first, and then perform the replacement operation, which leads to slow replacement efficiency and cumbersome operation, and thus greatly reduces practicality. Summary of the invention

[0004] The utility model aims to provide a pressure reducing valve. The device is adopted to work, thereby solving the problems of slow replacement efficiency and complicated operation when replacing the filter plate inside the pressure reducing valve.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure reducing valve comprises a valve body, a filter tube is arranged in the middle of the valve body, a tube cover is arranged at one end of the filter tube, an elastic clamp is arranged inside the filter tube, a filter mechanism is arranged inside the filter tube, the valve body is connected with the inside of the filter tube, a triangular slot one is opened at one end of the filter tube, a triangular slot two is opened on the inner wall surface of the tube cover, the elastic clamp comprises a spring one fixedly connected with the surface of the triangular slot one, a triangular plug block is fixedly installed at one end of the spring one, the triangular plug block matches and slides with the triangular slot one and the triangular slot two, and a shifting block is fixedly installed on the upper end of the triangular plug block. When the filter mechanism needs to be replaced, the triangular plug block is driven by shifting the shifting block to compress the spring one, so that the triangular plug block withdraws from the triangular slot two, and then the tube cover can be twisted to separate it from the filter tube, so that the filter mechanism can be disassembled to realize quick disassembly, and there is no need to disassemble the valve body and the connecting pipe, thereby greatly improving the replacement efficiency and thus improving its practicability.

[0006] Preferably, the filtering mechanism includes a frame, the frame matches the inner wall of the filter tube and is slidably connected, a filter screen is fixedly installed on the inner side of the frame, two sets of slide rails are fixedly installed on the inner wall surface of the filter tube, the frame matches the slide rails and is slidably connected, and the setting of the slide rails facilitates the entry of the entire filtering mechanism and at the same time plays a role in fixing the position of the frame, thereby ensuring normal and effective filtration of the filter screen.

[0007] Preferably, two pressing plates are fixedly installed on one side of the filter screen, and two groups of elastic members are fixedly installed on the inner wall surface of the filter pipe. The elastic member includes a second spring fixedly connected to the inner wall surface of the filter pipe. One end of the second spring away from the filter pipe is fixedly installed with an elastic plate. A groove is opened at one end of the elastic plate away from the second spring.

The frame 51 is matched with and slidably connected to the slide rails 22. The arrangement of the slide rails 22 facilitates the overall entry of the filtering mechanism 5 and at the same time fixes the position of the frame 51, ensuring the normal and effective filtering of the filter screen 52.

[0025] Combined with Figure 4 、 Figure 7 , two pressing plates 53 are fixedly installed on one side of the filter screen 52. Two groups of elastic members 23 are fixedly installed on the inner wall surface of the filtering pipe 2.

[0029] The specific working process and principle of the utility model are as follows: first, the flange 14 is arranged to facilitate quick connection with the pipe to be connected. When the filter mechanism 5 needs to be replaced during use, the triangular plug block 42 is driven by the dial block 43 to compress the spring 1 41, so that the triangular plug block 42 withdraws from the triangular slot 2 31, and then the pipe cover 3 can be twisted to separate it from the filter tube 2, so that the filter mechanism 5 can be disassembled to achieve quick disassembly, and there is no need to disassemble the valve body 1 and the connecting pipe, which greatly improves the replacement efficiency. When installing the filter mechanism 5, the pressure plate 53 is in contact with the groove 233, and pushes the spring plate 232 to compress the spring 2 231 and the telescopic rod 234. When the pipe cover 3 is separated from the filter tube 2 during replacement and disassembly, the spring 231 is reset and pushes the spring plate 232 to drive the pressure plate 53 to move horizontally, so that the filter mechanism 5 is pushed out of a part of the filter tube 2 for easy removal and replacement by personnel.
