Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve with a filtering function. Background Art

[0002] Valves are an important type of fluid control equipment in industry, involving many sectors of the national economy and are important basic equipment for the development of the national economy. Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, flow diversion, prevention of backflow, 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 shut-off valves to various valves used in extremely complex automatic control systems.

[0003] During the use of existing valves, impurities in the liquid entering the valve will affect the working efficiency of the valve. If the valve is used for too long, the impurities in the liquid will accumulate and the accumulated impurities will clog the valve, making the valve unusable and shortening the service life of the valve. To this end, we propose a valve with a filtering function to solve the above problem. Utility Model Content

[0022] See also Figure 1-4 In the utility model, a valve with a filtering function includes a valve housing 1, a limit baffle 13 and two limit bolts 16. An annular block 11 is fixedly installed on the inner wall of the valve housing 1, and a circular mounting frame 10 is fixedly installed on the right side of the annular block 11. A group of water leakage holes 12 are opened on the right side of the circular mounting frame 10, and a filter screen 18 is arranged inside the circular mounting frame 10. Two through holes 15 are opened on the outer surface of the limit baffle 13, and two threaded grooves 14 are opened on the outer surface of the circular mounting frame 10. One end of each limit bolt 16 passes through the through hole 15 and extends to the inside of the threaded groove 14, and the outer surface of one end of each limit bolt 16 is threadedly connected with the inner wall of the threaded groove 14.

[0023] The left side of the valve housing 1 is fixedly connected with a connecting pipe 3, the outer surface of which is provided with an external thread 4, and the outer surface of which is sleeved with a sealing ring 17. By inserting the connecting pipe 3 into the interior of the pipeline and threading the external thread 4 provided on the outer surface of the connecting pipe 3 with the inner wall of the pipeline, the device can be assembled with the pipeline. An annular connecting block 5 is fixedly installed on the outer surface of the valve housing 1, and the outer surface of the annular connecting block 5 is provided with a plurality of mounting holes 2 arranged at equal distances. By installing the annular connecting block 5 on the outer surface of the valve housing 1 and providing the mounting holes 2 on the outer surface of the annular connecting block 5, screws can be used to penetrate the mounting holes 2 and assemble them with the pipeline. By sleeved with a sealing ring 17 on the outer surface of the connecting pipe 3, a sealing effect can be achieved to prevent water from overflowing from the connection.

[0024] Two arc-shaped blocks 9 are fixedly installed on the inner wall of the valve housing 1, and a flow limiting plate 8 is arranged between the two arc-shaped blocks 9. When the left side surface and the right side surface of the flow limiting plate 8 are in contact with the two arc-shaped blocks 9 respectively, water can be blocked. A connecting rod 7 is fixedly installed on the upper surface of the flow limiting plate 8. The top end of the connecting rod 7 passes through the valve housing 1 and extends to the outside of the valve housing 1. An adjusting hand wheel 6 is fixedly installed on the top end of the connecting rod 7. By using the connecting rod 7 to connect the adjusting hand wheel 6 with the flow limiting plate 8, the user can adjust the angle of the flow limiting plate 8 by turning the adjusting hand wheel 6, thereby conveniently controlling the amount of water flow.

[0025] The working principle of the utility model is:

[0026] First, the user places the filter 18 inside the circular mounting frame 10, and then uses two limiting bolts 16 to penetrate the through holes 15 opened on the outer surface of the limiting baffle 13 and threadedly connect with the inner walls of the two threaded grooves 14 opened on the outer surface of the circular mounting frame 10. The limiting baffle 13 can firmly limit the filter 18 inside the circular mounting frame 10, and then the user inserts the connecting pipe 3 into the interior of the pipeline, so that the external thread 4 opened on the outer surface of the connecting pipe 3 is threadedly connected with the inner wall of the pipeline.
