Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an anti-clogging valve. Background Technology

[0002] Anti-clogging valves are designed to prevent blockages in pipelines or systems caused by solid particles, impurities, or other substances. These valves achieve their anti-clogging effect through special structural design and function, thereby ensuring the normal operation of the system and extending its service life.

[0003] Depending on the application scenario and technical requirements, anti-clogging valves can employ a variety of structures and materials. For example, some anti-clogging valves use a filter screen or filtration device inside the valve body to intercept solid particles, thereby preventing these particles from entering the valve and causing blockage. Furthermore, some valves employ special valve core designs, such as plunger-type or window-type valve cores, to reduce the stagnation area of ​​the medium during passage, thus lowering the likelihood of blockage.

[0004] In practical applications, anti-clogging valves are commonly used in pipeline systems containing media that are prone to sedimentation or have poor flowability, such as domestic sewage, industrial wastewater treatment, and gas transmission. These valves are typically designed with the characteristics of the media, such as particle size, viscosity, and density, in mind to ensure effective clogging prevention under various operating conditions.

[0005] A search revealed a Chinese utility model patent (publication number CN215110789U) for an anti-clogging valve, relating to the field of valve technology. Specifically, the anti-clogging valve includes a valve body with a valve cover at its top and a handle at its top. Positioning rings are engaged at both ends of the valve body, and a central rod is movably mounted in the center of each positioning ring. A drive turbine and a driven bevel gear are fixedly mounted on the outside of the central rod, and a connecting bracket is also fixedly mounted on the outside of the central rod. When fluid flows inside the valve body, the drive turbines on both sides rotate, thereby rotating the central rod and a cleaning brush. The rotating cleaning brush cleans impurities adhering to the inner wall of the valve body, preventing accumulation and clogging. It also prevents long-term adhesion of impurities to the inner wall of the valve body, thus preventing corrosion and extending the valve's service life.

[0006] However, this device often lacks the function of filtering impurities. When in use, if the valve lacks a filtering function, impurities in the pipeline (such as welding slag, rust, sludge, etc.) will directly enter the valve, causing blockage inside the valve, thereby reducing the flow or completely blocking the normal operation of the valve. Moreover, the device also lacks the function of easy filter replacement. With long-term use, impurities and particulate matter in the filter ring will gradually accumulate, eventually causing the filter to become clogged, which will seriously affect the flow and efficiency of the system. Utility Model Content

[0007] The purpose of this invention is to provide an anti-clogging valve to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A clog-resistant valve includes a pipe with a flange connected to one end of the pipe, an installation tube fixedly connected to the bottom of the valve, an installation groove inside the installation tube, a filter ring snapped into the installation groove, filter holes on the surface of the filter ring, a butt ring fixedly connected to one end of the filter ring, a connection hole on one end of the installation tube, a sealing cap snapped into the surface of the installation tube, a fixing hole on the surface of the sealing cap, and a fixing bolt threaded into the fixing hole.

[0010] Preferably, the surface of the mounting tube has a groove, and a sealing cap is snapped into the groove.

[0011] Preferably, a sealing block is fixedly connected to the surface of the sealing cover, and a sealing ring is fixedly connected to the surface of the sealing block.

[0012] Preferably, a fixing sleeve is fixedly connected to one end of the pipe, and a shaft seat is fixedly connected to one side of the fixing sleeve.

[0013] Preferably, a rotating shaft is rotatably connected inside the bearing seat, and a rotating scraper is fixedly connected to the surface of the rotating shaft.

[0014] Preferably, the flange surface has a mating hole, and a connecting bolt is threaded into the mating hole.

[0015] Preferably, a valve cover is fixedly connected to the top of the valve, and a handwheel is rotatably connected to the top of the valve cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This anti-clogging valve, in use, consists of an installation pipe, filter ring, filter hole, connecting ring, and sealing cap. When water flows into the valve through a pipe, the installation pipe is connected to the bottom of the valve. After the water flows into the filter ring inside the installation pipe, suspended solids, silt, rust, and other impurities in the water are filtered by the filter ring to ensure the purity of the water flow. By intercepting solid particles in the water flow, these impurities can be prevented from entering downstream equipment, reducing equipment wear and malfunctions, and extending the service life of the equipment, thereby achieving the effect of filtering impurities.

[0018] 2. This anti-clogging valve, through the installation pipe, connecting hole, sealing cap, fixing hole, installation groove, and fixing bolt, allows the filter element inside the filter ring to gradually become clogged by impurities in the fluid after prolonged use, resulting in a decrease in filtration capacity. At this time, the fixing bolt fixed in the fixing hole can be removed. After removing the fixing bolt, the sealing cap will detach from the installation pipe. Then, the filter ring inside the installation pipe can be removed for replacement or cleaning. After cleaning, the connecting ring of the filter ring is aligned with the installation groove in the installation pipe to complete the filter ring installation. Finally, the fixing hole on the sealing cap is aligned with the connecting hole on the installation pipe, and the fixing bolt is installed, thus achieving the effect of easy replacement.

[0025] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0026] A clog-resistant valve includes a pipe 1, a valve 2 connected to a flange at one end of the pipe 1, an installation pipe 3 fixedly connected to the bottom of the valve 2, an installation groove 4 inside the installation pipe 3, a filter ring 5 snapped into the installation groove 4, filter holes 6 on the surface of the filter ring 5, a connecting ring 7 fixedly connected to one end of the filter ring 5, a connection hole 8 at one end of the installation pipe 3, a sealing cap 9 snapped into the surface of the installation pipe 3, a fixing hole 10 on the surface of the sealing cap 9, and a fixing bolt 11 threaded into the fixing hole 10. In use, when water flows into the valve 2 through the pipe 1, the water, after flowing into the filter ring 5 connected inside the installation pipe 3, is filtered by the filter ring 5 to ensure the purity of the water flow. Intercepting solid particles in the water flow can prevent these impurities from entering downstream equipment, reducing equipment wear and malfunctions, and extending the service life of the equipment. After prolonged use, the filter element inside the filter ring 5 will gradually become clogged by impurities in the fluid, resulting in a decrease in filtration capacity. At this time, the fixing bolt 11 fixed in the fixing hole 10 can be removed. After removing the fixing bolt 11, the sealing cover 9 will detach from the installation tube 3. Then, the filter ring 5 inside the installation tube 3 can be removed for replacement or cleaning. After cleaning, the connecting ring 7 of the filter ring 5 can be aligned with the installation groove 4 inside the installation tube 3 to complete the installation of the filter ring 5. Then, the fixing hole 10 on the sealing cover 9 can be aligned with the connecting hole 8 on the installation tube 3 to install the fixing bolt 11, thus achieving normal use.

[0027] In this embodiment, preferably, a groove 12 is provided on the surface of the mounting tube 3, and a sealing cap 9 is snapped into the groove 12. In use, the groove 12 is provided on the surface of the mounting tube 3, and the groove 12 can be connected with the sealing cap 9 to complete the sealing of the mounting tube 3, thus achieving the function of installing the sealing cap 9.

[0028] In this embodiment, preferably, a sealing block 13 is fixedly connected to the surface of the sealing cover 9, and a sealing ring 14 is fixedly connected to the surface of the sealing block 13. In use, the sealing block 13 is connected to the surface of the sealing cover 9, and the sealing ring 14 connected to the surface of the sealing block 13 can prevent water from overflowing when the sealing cover 9 is installed on the installation pipe 3, thus achieving the sealing effect.

[0029] In this embodiment, preferably, a fixing sleeve 15 is fixedly connected to one end of the pipe 1, and a shaft seat 16 is fixedly connected to one side of the fixing sleeve 15. In use, the fixing sleeve 15 is connected to one end of the pipe 1, and the shaft seat 16 is fixed by the fixing sleeve 15 so that the rotating shaft 17 inside the shaft seat 16 can rotate, thus achieving the function of installing the rotating shaft 17.

[0030] In this embodiment, preferably, a rotating shaft 17 is rotatably connected inside the bearing seat 16, and a rotating scraper 18 is fixedly connected to the surface of the rotating shaft 17. In use, the rotating shaft 17 is connected inside the bearing seat 16. When water flows through the pipe 1, the rotating scraper 18 connected to the surface of the rotating shaft 17 will be driven to rotate by the water flow. During the process of the rotating scraper 18 being driven to rotate by the water flow, the edge of the rotating scraper 18 will scrape the inner surface of the pipe 1 so that impurities in the water flow will not adhere to it, thus achieving the function of scraping off surface impurities.

[0031] In this embodiment, preferably, a mating hole 19 is provided on the flange surface, and a connecting bolt 20 is threaded inside the mating hole 19. In use, the mating hole 19 is provided on the flange surface, and the connecting bolt 20 can be installed through the mating hole 19 to complete the mating installation when connecting the pipe 1 and the valve 2, thus achieving the purpose of mating.

[0032] In this embodiment, preferably, a valve cover 21 is fixedly connected to the top of the valve 2, and a handwheel 22 is rotatably connected to the top of the valve cover 21. In use, the valve cover 21 is connected to the top of the valve 2, and the valve cover 21 provides a fixed position for the handwheel 22 connected to the top, ensuring that the handwheel 22 can be normally driven and opened and closed, thus ensuring the normal operation of the valve 2 and achieving the function of normal opening and closing.

[0033] In this embodiment, an anti-clogging valve 2, through the arrangement of an installation pipe 3, a filter ring 5, a filter hole 6, a connecting ring 7, and a sealing cap 9, allows water to flow into the valve 2 through the pipe 1. The installation pipe 3 is connected to the bottom of the valve 2, and the water flows into the filter ring 5 connected inside the installation pipe 3. Suspended solids, silt, rust, and other impurities in the water are filtered by the filter ring 5, ensuring the purity of the water flow. By intercepting solid particles in the water flow, these impurities can be prevented from entering downstream equipment, reducing equipment wear and malfunctions, and extending the service life of the equipment, thereby achieving the effect of filtering impurities. The installation pipe 3, connecting hole 8, sealing cap 9, fixing hole 10, and installation groove 4 are also included. With the setting of the fixing bolt 11, after the filter ring 5 has been used for a long time, the filter element inside the filter ring 5 will gradually be blocked by impurities in the fluid, resulting in a decrease in filtration capacity. At this time, the fixing bolt 11 fixed in the fixing hole 10 can be removed. After removing the fixing bolt 11, the sealing cover 9 will be detached from the installation tube 3. Then, the filter ring 5 in the installation tube 3 can be taken out for replacement or cleaning. After cleaning, the docking ring 7 of the filter ring 5 is docked with the installation groove 4 in the installation tube 3 to complete the installation of the filter ring 5. Then, the fixing hole 10 on the sealing cover 9 is aligned with the connecting hole 8 on the installation tube 3 and the fixing bolt 11 is installed, thereby achieving the effect of easy replacement.
