DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] During the pipeline construction process, valves are required. The valves provided by the present invention are specifically used for connecting pipelines. During the process of using this equipment to connect pipelines, it is important to ensure that the installation of the valves meets the design requirements, including whether the connecting pipelines are firm and whether the sealing performance is good, to avoid leakage during use. Before the first use, check whether the cleaning mechanism 2 has been thoroughly cleaned to avoid affecting the initial circulation effect.

[0020] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a corrosion-resistant valve casting that is easy to maintain, including a valve body 1, a cleaning mechanism 2 is provided on one side of the valve body 1, the cleaning mechanism 2 includes a threaded block 203, a through hole is opened on one side of the threaded block 203, a connecting shaft 205 is rotatably connected in the through hole, a filter cartridge 206 is fixedly connected to the outer wall of the connecting shaft 205, a plurality of equidistant cleaning brushes 207 are fixedly connected to the outer wall of the filter cartridge 206, a connecting plate 4 is fixedly connected to the inner walls on both sides of the valve body 1, a notch is opened on one side of the connecting plate 4, a sealing plate 5 is slidably connected in the notch.

[0021] like Figure 2 As shown, a through hole is provided on one side of the valve body 1, in which a fixed pipe 201 is fixedly connected, the fixed pipe 201 and the threaded block 203 are screwed together, a through hole is provided on the top of the fixed pipe 201, in which a water inlet pipe 202 is fixedly connected, a rotating plate 204 is fixedly connected to one side of the threaded block 203, a servo motor 208 is installed on one side of the rotating plate 204, and the output end of the servo motor 208 is connected to the connecting shaft 205, a notch is provided at the bottom of the fixed pipe 201, a sedimentation funnel 209 is fixedly connected in the notch, and a sewage pipe 210 is screwed to the bottom of the sedimentation funnel 209.

[0022] It should be noted that during use, the rotating plate 204 is first manually twisted to drive the threaded block 203 and the fixed pipe 201 to connect, and then the water source enters the fixed pipe 201 through the water inlet pipe 202. In this process, the servo motor 208 drives the connecting shaft 205 to rotate, driving the filter cartridge 206 and the cleaning brush 207 to rotate to filter impurities and dirt in the water flow. The impurities and dirt enter the sewage pipe 210 through the sedimentation funnel 209. The cleaning mechanism 2 is reasonably designed and can collect and treat sewage in time during the cleaning process, thereby avoiding the impact of pollutants generated during the cleaning process on the environment.

[0023] like Figure 3 As shown, a through hole is opened on the side of the valve body 1 away from the fixed pipe 201, and a drain pipe 3 is fixedly connected to the through hole.

[0024] It should be noted that during use, when water flows into the valve body 1 through the cleaning mechanism 2, before that, the rotating ring 8 on the support frame 6 is manually operated to drive the screw 7 to rotate, so that the sealing plate 5 moves up and down under the action of the connecting plate 4, so that the water flows out through the drain pipe 3. The parts can be easily disassembled, inspected and replaced, which shortens the downtime, improves work efficiency, facilitates regular inspection and replacement, and extends the service life of the cleaning equipment.

[0025] Working principle: First, manually twist the rotating plate 204 to drive the threaded block 203 and the fixed pipe 201 to connect, and then the water source enters the fixed pipe 201 through the water inlet pipe 202. In this process, the servo motor 208 drives the connecting shaft 205 to rotate, driving the filter cartridge 206 and the cleaning brush 207 to rotate to filter the impurities and dirt in the water flow. The impurities and dirt enter the sewage pipe 210 through the sedimentation funnel 209. At the same time, when the water flows into the valve body 1 through the cleaning mechanism 2, before that, the rotating ring 8 on the support frame 6 is manually operated to drive the screw 7 to rotate, so that the sealing plate 5 moves up and down under the action of the connecting plate 4, so that the water flows through the drain pipe 3. The device can effectively remove dirt, sediment and other impurities inside the valve, ensure the fluidity and efficiency of the valve in the working state, thereby reducing the occurrence of blockage and failure.
