[0002] Gate valves are a common type of fluid control valve, mainly used to completely open or close the fluid in a pipeline, but not to regulate the flow rate. They are mainly used in urban water supply, fire protection pipelines, etc.

[0003] A search revealed that patent CN218152434U discloses a gate valve with a filtering function. Through the filter plate, it can filter the medium flowing into the pipe, providing a filtering effect and improving the functionality of the structure during use.

[0004] The aforementioned patent describes a device that uses a detachable fixing plate to facilitate disassembly and cleaning of the filter plate, ensuring good filtration of the medium. However, during the filtration process, the fixing plate needs to be removed to clean impurities, resulting in poor filtration performance after long-term use and making replacement cumbersome. Therefore, we provide a sealing gate valve with a filtration function to solve the above problems. Utility Model Content

[0007] The filtration mechanism includes a housing, a screw thread is fixedly connected to the top surface of the housing, the screw thread is threaded to the bottom end of the outer surface of the plug, and a partition is fixedly connected to the middle of the housing.

[0008] The water inlet pipe is fixedly connected to the bottom side of the outer casing, the water delivery pipe is fixedly connected to the top side of the outer casing, a sewage discharge funnel is fixedly connected to the bottom surface of the outer casing, and a screw thread is fixedly connected to the bottom surface of the sewage discharge funnel.

[0009] A further improvement of this utility model is that: the plug is threaded inside the screw hole, a bracket is fixedly connected to the top surface of the outer shell, a filter element device is movably connected inside the bracket, one end of the filter element device is movably connected inside the partition, and a cleaning device is provided inside the filter element device.

[0010] A further improvement of the present invention is that the filter element device includes a fixing plate, the fixing plate is movably connected to the top surface of the bracket, a frame is fixedly connected to the bottom surface of the fixing plate, the frame is movably connected to the inside of the outer shell, and a reinforcing rod is fixedly connected to the inside of the frame.

[0011] A further improvement of this utility model is that: a secondary filter screen is fixedly connected inside the reinforcing rod, a leak-proof plate is fixedly connected to the bottom surface of the fixing plate, the leak-proof plate is movably connected inside the partition, and an installation bracket is fixedly connected inside the leak-proof plate.

[0012] A further improvement of this utility model is that: a conical frame is fixedly connected to the bottom surface of the leak-proof plate, a primary filter screen is fixedly connected inside the conical frame, and a guide plate is fixedly connected to the bottom surface of the conical frame.

[0013] A further improvement of the present invention is that the cleaning device includes a rotating shaft, which is rotatably connected inside the mounting bracket. One end of the rotating shaft is rotatably connected inside the frame.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a sealed gate valve with a filtration function, which is connected to the outlet port by a flange. Water flows into the inside of the housing from the inlet pipe and accumulates on the bottom surface of the housing. When enough water accumulates, it flows into the inside of the conical frame from the gaps of the primary filter screen and continues to rise into the inside of the frame.

[0017] The water flowing through the primary filter screen will have its internal impurities filtered out by the conical frame and the special shape of the primary filter screen due to the conical frame and the primary filter screen itself. At the same time, it will reduce the possibility of impurities adhering to the surface of the primary filter screen. The filtered impurities will remain inside the drain funnel. The plug can be removed periodically to allow the water to flow out from the drain funnel and the screw port, and the impurities will be carried away by the impact force of the water flow.

[0018] Water flows through a primary filter into the frame and is forced through a secondary filter by water pressure to flow into the top of the partition. The secondary filter then filters the water again to ensure its cleanliness. The water that accumulates on the top of the partition flows into the switch mechanism through a water pipe.

[0019] 2. This utility model provides a sealing gate valve with a filtration function. When water flows from the inside of the leak-proof plate into the inside of the frame, the flow of water will generate thrust on the blades, causing the blades to rotate around the pivot. At this time, the scraper on the side of the blades will scrape away any small impurities that may be attached to the inside of the secondary filter screen, ensuring its passage.

[0020] 3. This utility model provides a sealing gate valve with a filtering function. Filtered water flows into the ball valve through the ball valve. The state of the sealing baffle inside the ball valve can be controlled by the rotating rod, which can achieve the effect of opening and closing the device. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] Example 1: As Figure 1-5 As shown, this utility model provides a sealing gate valve with a filtering function, including a plug 1, a filtering mechanism 2 is provided on the bottom surface of the plug 1, an inlet pipe 6 is fixedly connected to the input end of the filtering mechanism 2, a flange 7 is fixedly connected to the side of the inlet pipe 6, a plug 3 is threadedly connected to the bottom surface of the filtering mechanism 2, a water supply pipe 4 is fixedly connected to the output end of the filtering mechanism 2, and a switching mechanism 5 is provided on the side of the water supply pipe 4.

[0029] The filter mechanism 2 includes a housing 21, a screw thread 22 is fixedly connected to the top surface of the housing 21, the screw thread 22 is threaded to the bottom end of the outer surface of the plug 1, and a partition 25 is fixedly connected to the middle of the housing 21.

[0030] The water inlet pipe 6 is fixedly connected to the bottom side of the outer casing 21, the water delivery pipe 4 is fixedly connected to the top side of the outer casing 21, the bottom surface of the outer casing 21 is fixedly connected to the sewage discharge funnel 23, and the bottom surface of the sewage discharge funnel 23 is fixedly connected to the screw thread 24.

[0031] The plug 23 is threaded inside the screw hole 24. The top surface of the inner shell 21 is fixedly connected to the bracket 27. The filter element device 26 is movably connected inside the bracket 27. The filter element device 26 includes a fixing plate 261, which is movably connected to the top surface of the bracket 27. The bottom surface of the fixing plate 261 is fixedly connected to a frame 262, which is movably connected inside the shell 21. A reinforcing rod 263 is fixedly connected inside the frame 262.

[0032] The reinforcing rod 263 is internally fixedly connected to a secondary filter 264, and the bottom surface of the fixing plate 261 is fixedly connected to a leak-proof plate 266. The leak-proof plate 266 is movably connected inside the partition 25, and the leak-proof plate 266 is internally fixedly connected to a mounting bracket 269.

[0033] A conical frame 267 is fixedly connected to the bottom surface of the leak-proof plate 266. A primary filter screen 268 is fixedly connected inside the conical frame 267. A guide plate 265 is fixedly connected to the bottom surface of the conical frame 267.

[0034] One end of the filter element device 26 is movably connected to the inside of the partition plate 25, and a cleaning device 28 is provided inside the filter element device 26.

[0035] In this embodiment, both plug 1 and plug 3 serve to prevent leakage and are connected to the top and bottom surfaces of the outer casing 21 via screw 22 and screw 24. The fixing plate 261 is movable on the top surface of the bracket 27. When plug 1 is used for fixing, the bracket 27 and plug 1 will squeeze the fixing plate 261 to ensure the stability of the filter element device 26. There are four reinforcing rods 263 to enhance the overall strength of the fixing plate 261. The leak-proof plate 266 will block the opening of the partition 25 to ensure that the water flows in from the opening end of the primary filter screen 268. The mesh size of the secondary filter screen 264 is larger than that of the primary filter screen 268, which can further filter the water flow.

[0036] The flange 7 is connected to the outlet port. Water flows into the interior of the housing 21 from the inlet pipe 6 and accumulates on the bottom surface of the housing 21. When enough water accumulates, it flows into the interior of the conical frame 267 through the gaps in the primary filter screen 268 and continues to rise into the interior of the frame 262.

[0037] The water flowing through the primary filter 268 will have its internal impurities filtered out by the primary filter 268 due to the special shape of the conical frame 267 and the primary filter 268. At the same time, it will reduce the possibility of impurities adhering to the surface of the primary filter 268. The filtered impurities will remain inside the drain funnel 23. The plug 23 can be removed periodically to allow the water to flow out from the drain funnel 23 and the screw port 24. The impurities will be carried away by the impact force of the water flow.

[0038] Water flows through a first screening process into the interior of frame 262. Under the action of water pressure, the water flows through the secondary filter 264 and into the top surface of partition 25. At this time, the secondary filter 264 will filter the water again to ensure the cleanliness of the water. The water accumulated on the top surface of partition 25 will flow into the interior of switch mechanism 5 through water supply pipe 4.

[0039] Example 2: As Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the cleaning device 28 includes a rotating shaft 281, which is rotatably connected inside the mounting bracket 269. One end of the rotating shaft 281 is rotatably connected inside the frame 262. A blade 282 is fixedly connected to the outer surface of the rotating shaft 281, and a scraper 283 is fixedly connected to the side of the blade 282. The scraper 283 is movably connected inside the secondary filter 264.

[0040] In this embodiment, when water flows from the inside of the leak-proof plate 266 into the inside of the frame 262, the flow of water will generate thrust on the blade 282, causing the blade 282 to rotate around the pivot 281. At this time, the scraper 283 on the side of the blade 282 will scrape away any small impurities that may be attached to the inside of the secondary filter screen 264, ensuring its passability.

[0041] Example 3: As Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the switching mechanism 5 includes a connecting pipe 51, which is fixedly connected to the side of the water supply pipe 4. A ball valve 52 is fixedly connected to the side of the connecting pipe 51. A sealing baffle 53 is rotatably connected inside the ball valve 52. One end of the sealing baffle 53 passes through the top surface of the ball valve 52 and is fixedly connected to a rotating rod 54.

[0042] In this embodiment, filtered water flows into the ball valve 52 through the ball valve 52. The state of the sealing baffle 53 inside the ball valve 52 can be controlled by the rotating rod 54, which can control the flow rate and switch the device on and off.

[0043] The working principle of this sealing gate valve with filtering function will be explained in detail below.

[0044] like Figure 1-5 As shown, by connecting the flange 7 to the outlet port and the ball valve 52 output end to the inlet port, water will flow from the inlet pipe 6 into the interior of the housing 21 and accumulate on the bottom surface of the housing 21. When enough water accumulates, it will flow from the gap of the primary filter screen 268 into the interior of the conical frame 267 and continue to rise into the interior of the frame 262.

[0045] The water flowing through the primary filter 268 will have its internal impurities filtered out by the primary filter 268 due to the special shape of the conical frame 267 and the primary filter 268. At the same time, it will reduce the possibility of impurities adhering to the surface of the primary filter 268. The filtered impurities will remain inside the drain funnel 23. The plug 23 can be removed periodically to allow the water to flow out from the drain funnel 23 and the screw port 24. The impurities will be carried away by the impact force of the water flow.

[0046] Water flows through a first screening process into the interior of frame 262. The water pressure forces the water to pass through the secondary filter 264 and flow into the top surface of partition 25. At this time, the secondary filter 264 will filter the water again to ensure the cleanliness of the water. The water accumulated on the top surface of partition 25 will flow into the interior of switch mechanism 5 through water pipe 4.

[0047] When water flows from the inside of the leak-proof plate 266 into the inside of the frame 262, the flow of water will generate thrust on the blade 282, causing the blade 282 to rotate around the shaft 281. At this time, the scraper 283 on the side of the blade 282 will scrape away any small impurities that may be attached to the inside of the secondary filter screen 264, ensuring its passability.

[0048] Filtered water flows into the ball valve 52 through the ball valve 52. The state of the sealing baffle 53 inside the ball valve 52 can be controlled by the rotating rod 54, which can achieve the effect of opening and closing the device.

[0049] When the device has poor throughput, the plug 1 can be removed and the filter element 26 can be taken out from the inside of the housing 21 and replaced with a new filter element 26 to restore the device to its optimal throughput.

[0050] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all modifications or improvements made without departing from the spirit and concept of the present invention are within the protection scope of the present invention.
