[0002] With population growth and economic development, the rational allocation and efficient utilization of water resources have become key issues. In the water supply system, whether it is an urban water supply network, industrial water supply or rural centralized water supply facilities, it is necessary to ensure the stability and accuracy of water supply. Water supply equipment needs to meet the water demand of different regions and different users at different times. This requires precise control of water flow, and flow stop devices play a vital role in this.

[0003] However, during the use of the existing flow-stop device for water supply equipment, impurities will gradually accumulate on the filter over time, and the resistance of water flow through the filter will greatly increase, resulting in a sharp drop in filtration efficiency and an inability to effectively remove impurities in the water. Utility Model Content

[0004] The purpose of the utility model is to provide a flow-stop device for water supply equipment. By setting a cleaning mechanism, the problem that in the use of the existing flow-stop device for water supply equipment, impurities will gradually accumulate on the filter screen over time, and the resistance of water flow through the filter screen will greatly increase, resulting in a sharp drop in filtration efficiency and an inability to effectively remove impurities in the water is solved.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a flow-stopping device for water supply equipment, comprising a main body, on which a cleaning mechanism and a one-way flow mechanism are provided;

[0007] The main body is provided with a plurality of mounting holes, the inner wall of the main body is fixedly connected to a filter screen, the cleaning mechanism includes a cleaning assembly and a limiting assembly, the cleaning assembly includes a cross support frame 1 fixedly connected to the inner wall of the main body, a rotating shaft is rotatably passed through the central axis of the cross support frame 1, and an impeller is fixedly connected to the right extension of the rotating shaft.

[0008] Furthermore, a circular ring 1 is fixedly connected to the left extension portion of the rotating shaft, and a plurality of filter scrapers are fixedly connected to the outer wall of the circular ring 1, and the left sides of the plurality of filter scrapers are in contact with the filter.

[0009] Furthermore, a plurality of connecting rods are fixedly connected to the outer wall of the rotating shaft, and a plurality of connecting rods are fixedly connected to inner wall scrapers on one side away from the rotating shaft, and a plurality of inner wall scrapers are in contact with the inner wall of the main body on one side away from the rotating shaft.

[0010] Furthermore, the limiting assembly includes a rotation groove provided in the cross support frame 1, a clamping ring is fixedly connected to the outer wall of the cross support frame 1, and the outer wall of the clamping ring rotates and extends into the rotation groove.

[0011] Furthermore, the one-way flow mechanism includes a second cross support frame fixedly connected to the inner wall of the main body, and a plurality of water leakage grooves are provided on the second cross support frame.

[0012] Furthermore, a second circular ring is fixedly connected to the inner wall of the main body, and a piston is slidably connected to the inner wall of the second circular ring.

[0013] Furthermore, a telescopic rod is fixedly connected to the right side of the second cross support frame, the left side of the telescopic rod is fixedly connected to the piston, a spring is sleeved on the outer wall of the telescopic rod, the left side of the spring is fixedly connected to the second cross support frame, and the right side of the spring is fixedly connected to the piston.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting up a cleaning mechanism, when water is supplied, water will drive the impeller to rotate. When the impeller rotates, it will drive the rotating shaft to rotate stably in the rotating groove under the action of the clamping ring. When the rotating shaft rotates, it will drive the filter scraper on the ring to clean the filter. When the filter scraper cleans the filter, it will also drive the inner wall scraper on the connecting rod to clean the inner wall of the main body, so that the filter can always maintain good permeability, ensuring that while supplying water, impurities in the water are continuously and efficiently filtered, providing a clean water source for subsequent water use links, and preventing excessive accumulation of impurities from damaging the filter, thereby extending the service life of the filter and reducing the frequency of filter replacement;

[0016] 2. By setting up a one-way flow mechanism, when water flows, the piston in the second ring moves to the left under the action of water pressure. When the piston moves to the left, the telescopic rod and the spring are compressed. The spring undergoes elastic deformation and generates elastic force under the action of this pressure. When the piston is completely separated from the second ring, a gap will be generated between the piston and the telescopic rod, and water will flow out from this gap. Due to the elastic action of the spring, the gap between the piston and the telescopic rod will increase with the increase of water pressure, which can ensure that the water-using equipment has a stable water supply, thereby ensuring the accuracy and stability of production or experiments. When the water supply is stopped, the water pressure disappears. At this time, the piston is reset under the elastic force of the spring, thereby avoiding water backflow, so that the pressure wave generated by the water flow impacting the pipeline when the valve is suddenly closed due to the inertia of the water flow can be effectively prevented, thereby protecting the integrity and safety of the water supply pipeline system.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The limiting component 22 includes a rotation groove 221 opened in the cross support frame 211, and a clamping ring 222 is fixedly connected to the outer wall of the cross support frame 211. The outer wall of the clamping ring 222 rotates and extends into the rotation groove 221. By setting up the cleaning mechanism 2, the filter 102 can always maintain good permeability, ensuring that while supplying water, impurities in the water are continuously and efficiently filtered, providing a clean water source for subsequent water use links, and preventing excessive accumulation of impurities from damaging the filter 102, thereby extending the service life of the filter 102 and reducing the frequency of replacing the filter 102.

[0028] The one-way circulation mechanism 3 includes a cross support frame 2 301 fixedly connected to the inner wall of the main body 1, and a plurality of water leakage grooves 302 are opened on the cross support frame 2 301. A circular ring 2 303 is fixedly connected to the inner wall of the main body 1, and a piston 304 is slidably connected to the inner wall of the circular ring 2 303. A telescopic rod 305 is fixedly connected to the right side of the cross support frame 2 301, and the left side of the telescopic rod 305 is fixedly connected to the piston 304.

[0029] A specific application of this embodiment is as follows: when in use, first install the main body 1 between the two water pipes through the installation hole 101, so that its right side is installed at the water inlet end and its left side is installed at the water outlet end. When the device is in use, water flows from the right to the left. When water flows, the piston 304 in the second ring 303 moves to the left under the action of water pressure. When the piston 304 moves to the left, the telescopic rod 305 and the spring 306 are compressed.

When the water supply is stopped, the water pressure disappears. At this time, the piston 304 is reset under the elastic force of the spring 306. , thereby avoiding water backflow, so that it can effectively prevent the pressure wave generated by the water flow impacting the pipeline when the valve is suddenly closed due to the inertia of the water flow, thereby protecting the integrity and safety of the water supply pipeline system. During water supply, water will drive the impeller 217 to rotate. When the impeller 217 rotates, it will drive the rotating shaft 212 to rotate stably in the rotating groove 221 under the action of the clamping ring 222. When the rotating shaft 212 rotates, it will drive the filter scraper 214 on the ring 1 213 to clean the filter 102. While the filter scraper 214 cleans the filter 102, it will also drive the inner wall scraper 216 on the connecting rod 215 to clean the inner wall of the main body 1, so that the filter 102 can always maintain good permeability, ensuring that impurities in the water are continuously and efficiently filtered during water supply, providing a clean water source for subsequent water use links, and preventing excessive accumulation of impurities from damaging the filter 102, thereby extending the service life of the filter 102 and reducing the frequency of replacing the filter 102.
