Description

Technical Field

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

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. They are control components in fluid conveying systems and have functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves can be installed with filtering systems to prevent impurities or excess particles in the pipeline from contaminating the system and blocking the pipeline, thereby protecting related equipment and systems.

[0003] The existing devices have some disadvantages during use, for example: the existing valves lack a filtering system. Valves without a filtering system cannot effectively remove impurities in the fluid, such as particles, suspended matter, oil stains, etc. These impurities will enter the pipeline system with the fluid, causing wear and tear on the equipment and reducing the service life of the equipment. Utility Model Content

[0004] The utility model aims to provide a valve with a filtering structure to solve the problem that the existing valve has no filtering system and cannot clean the filtering layer.

[0005] The utility model provides the following technical solutions: a valve with a filtering structure, comprising a valve body, flanges are fixedly connected to the outer sides of both ends of the valve body, a valve ball is arranged inside the valve body, a rotating shaft is fixedly connected to one side of the valve ball, an end of the rotating shaft away from the valve ball passes through one side of the valve body and is rotatably connected to the one side of the valve body, a rotating handle is fixedly connected to the top end of the rotating shaft, a filtering assembly is arranged inside the valve body, and a cleaning assembly for cleaning the filtering assembly is arranged inside the valve body on the side close to the filtering assembly.

[0006] In the above scheme, the flange enables the valve to be easily installed in the pipeline system while ensuring the sealing and pressure resistance. By rotating the rotating handle, the rotating shaft rotates, thereby driving the valve ball to rotate, thereby realizing the on-off control of the fluid.

[0007] As a preferred embodiment of the above technical solution, the filter assembly includes a water inlet and a water outlet respectively arranged at two ends of the valve body, and a filter layer is fixedly connected to the inner side of one end of the valve body close to the water outlet.

[0008] In the above scheme, the design of the water inlet and outlet ensures that the fluid can smoothly enter and flow out of the valve body. By setting a filter layer inside the valve body, impurities in the fluid, such as particles, suspended matter, etc., can be effectively removed to improve the purity of the fluid.

[0009] As a preferred embodiment of the above technical solution, the cleaning assembly includes a mounting block fixedly connected to the inner wall of the valve body, the mounting block is provided with a rotation hole, a rotating rod is laterally arranged on the inner side of the valve body, the rotating rod laterally penetrates the rotating hole, and the rotating rod rotates in the rotating hole through a bearing.

[0010] In the above solution, the design of the rotating hole allows the rotating rod to rotate smoothly in the mounting block, effectively avoiding the problem of the rotating rod being stuck or rotating poorly due to friction, obstruction by foreign matter or other factors.

[0011] As a preferred embodiment of the above technical solution, an impeller is fixedly sleeved on the outer side of one end of the rotating rod close to the valve ball, a fixed block is fixedly connected to one end of the rotating rod close to the filter layer, and a scraper is fixedly connected to one end of the fixed block away from the rotating rod, and the scraper is in contact with the surface of the filter layer.

[0012] In the above scheme, when the fluid passes through, the impeller will rotate due to the impact of the fluid, thereby driving the rotating rod and the scraper on the fixed block to rotate together. During the rotation process, the scraper will stick to the surface of the filter layer, effectively removing accumulated impurities and maintaining the cleanliness of the filter layer and the filtering effect.

[0013] As a preferred embodiment of the above technical solution, a drain pipe is fixedly connected to the outer side of one end of the valve body close to the filter layer, the drain pipe is communicated with the valve body, and a drain cover is threadedly sleeved on the outer side of one end of the drain pipe away from the valve body.

[0014] In the above scheme, by opening the drain cover, the impurities and dirt scraped off the filter layer can be easily discharged through the drain pipe, avoiding the accumulation of impurities and dirt to wear and corrosion inside the valve body, thereby reducing the occurrence of equipment failure.

[0015] As a preferred embodiment of the above technical solution, an annular groove is formed on the inner bottom wall of the sewage discharge cover, and a sealing gasket is arranged in the annular groove.

[0016] In the above scheme, the addition of the sealing gasket improves the sealing between the drain cover and the drain pipe. When the drain cover is screwed on the drain pipe, the sealing gasket will be deformed by pressure, thereby fitting closely to the surface of the drain pipe, effectively preventing leakage of fluid or impurities.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] In the utility model, the filter layer can effectively remove impurities in the fluid, such as particles, suspended matter, etc. If these impurities are not removed, they will damage subsequent equipment or processes and affect product quality. Through the filtering effect of the filter layer, the purity of the fluid is significantly improved. When the fluid passes through the valve body, the impeller will rotate due to the impact of the fluid. The rotation of the impeller drives the rotating rod and the scraper on the fixed block to rotate together. The scraper will adhere to the surface of the filter layer during the rotation process to effectively remove accumulated impurities. This automatic cleaning function greatly reduces the frequency of manual cleaning, increases the service life of the filter layer, and also ensures the continuous and stable filtering effect.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Example 1

[0027] like Figure 1-Figure 2As shown, the utility model provides a technical solution: a valve with a filtering structure, including a valve body 10, flanges 11 are fixedly connected to the outer sides of both ends of the valve body 10, a valve ball 12 is arranged inside the valve body 10, a rotating shaft 13 is fixedly connected to one side of the valve ball 12, an end of the rotating shaft 13 away from the valve ball 12 passes through one side of the valve body 10 and is rotatably connected to one side of the valve body 10, a rotating handle 14 is fixedly connected to the top of the rotating shaft 13, a filtering assembly is arranged inside the valve body 10, and a cleaning assembly for cleaning the filtering assembly is arranged inside the valve body 10 on the side close to the filtering assembly. During specific use, the flange 11 enables the valve to be easily installed in the pipeline system while ensuring sealing and pressure resistance. By rotating the rotating handle 14, the rotating shaft 13 is driven to rotate, thereby driving the valve ball 12 to rotate, thereby realizing on-off control of the fluid.

[0028] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, the cleaning component includes a mounting block 30 fixedly connected to the inner wall of the valve body 10, and a filter layer 22 is fixedly connected to the inner side of one end of the valve body 10 close to the water outlet 21. During specific use, the design of the water inlet 20 and the water outlet 21 ensures that the fluid can smoothly enter and flow out of the valve body 10. By arranging the filter layer 22 inside the valve body 10, impurities in the fluid, such as particles, suspended matter, etc., can be effectively removed, thereby improving the purity of the fluid.

[0029] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, a mounting block 30 is fixedly connected to the inner side of one end of the valve body 10 near the water outlet 21, and a rotating hole 31 is opened in the mounting block 30. A rotating rod 32 is transversely arranged on the inner side of the valve body 10, and the rotating rod 32 transversely passes through the rotating hole 31, and the rotating rod 32 rotates in the rotating hole 31 through a bearing. During specific use, the design of the rotating hole 31 allows the rotating rod 32 to rotate smoothly in the mounting block 30, effectively avoiding the problem of the rotating rod 32 getting stuck or rotating poorly due to friction, foreign matter obstruction or other factors.

[0030] As an implementation method in this embodiment, Figure 2 , Figure 3 and Figure 4As shown, an impeller 40 is fixedly sleeved on the outer side of one end of the rotating rod 32 close to the valve ball 12, a fixed block 41 is fixedly connected to one end of the rotating rod 32 close to the filter layer 22, and a scraper 42 is fixedly connected to one end of the fixed block 41 away from the rotating rod 32, and the scraper 42 is in contact with the surface of the filter layer 22. During specific use, when the fluid passes through, the impeller 40 will be impacted by the fluid and rotate, thereby driving the rotating rod 32 and the scraper 42 on the fixed block 41 to rotate together, and the scraper 42 will be in close contact with the surface of the filter layer 22 during the rotation process, so as to effectively remove accumulated impurities and keep the filter layer 22 clean and have a filtering effect.

[0031] As an implementation method in this embodiment, Figure 5 As shown, a drain pipe 50 is fixedly connected to the outer side of one end of the valve body 10 close to the filter layer 22, and the drain pipe 50 is communicated with the valve body 10. A drain cover 51 is threadedly sleeved on the outer side of one end of the drain pipe 50 away from the valve body 10. During specific use, by opening the drain cover 51, impurities and dirt scraped off the filter layer 22 can be easily discharged through the drain pipe 50, avoiding the accumulation of impurities and dirt to wear and corrosion inside the valve body 10, thereby reducing the occurrence of equipment failures.

[0032] As an implementation method in this embodiment, Figure 5 As shown, the inner bottom wall of the drain cover 51 is provided with an annular groove 60, and a sealing gasket 61 is arranged in the annular groove 60. During specific use, the addition of the sealing gasket 61 improves the sealing between the drain cover 51 and the drain pipe 50. When the drain cover 51 is tightened on the drain pipe 50, the sealing gasket 61 will be deformed by the pressure, thereby tightly fitting the surface of the drain pipe 50, effectively preventing the leakage of fluid or impurities.

[0033] Working principle: Through the flange 11, the valve can be easily installed in the pipeline system and ensure the sealing and pressure resistance between the pipeline and the valve. By rotating the rotating handle 14, the rotating shaft 13 is driven to rotate, thereby controlling the rotation of the valve ball 12. The valve ball 12 will open or close the valve during the rotation process to achieve on-off control of the fluid. When the fluid passes through the valve, the filter layer 22 can effectively remove impurities in the fluid, such as particles, suspended matter, etc., to improve the purity of the fluid. When the fluid passes and drives the impeller 40 to rotate, the rotating rod 32 and the scraper 42 will also rotate accordingly. The scraper 42 will cling to the surface of the filter layer 22 during the rotation process, effectively removing accumulated impurities and maintaining the cleanliness and filtering effect of the filter layer 22. When it is necessary to clean the impurities and dirt scraped off the filter layer 22, the drain cover 51 can be opened to discharge the impurities and dirt through the drain pipe 50. When the drain cover 51 is tightened on the drain pipe 50, the sealing gasket 61 will be deformed by pressure and tightly fit the surface of the drain pipe 50, effectively preventing the leakage of fluid or impurities.

[0034] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
