Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a control valve for a tap water filtration tank. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. Valves need to be installed on the pipes connected to the tap water filter tank to control the water flow.

[0003] However, existing technologies have some problems: due to the large amount of impurities in tap water filtration tanks, in order to prevent some smaller impurities from passing through the filter components in the filtration tank and flowing into the valve, causing valve blockage, existing control valves usually have filter frames to intercept impurities. However, the filter frames in existing valves are usually installed inside the valve with multiple bolts. When cleaning the impurities in the filter frames, workers need to remove multiple bolts, and may even need to remove the valve from the pipeline to take out the filter frames inside the valve for cleaning. This operation is cumbersome and inefficient. Therefore, we propose a control valve for tap water filtration tanks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a control valve for a tap water filtration tank.

[0005] The purpose of this utility model is achieved as follows: a control valve for a tap water filtration tank includes a valve body, a valve gate assembly is provided on the valve body, a filter frame body is movably installed inside the valve body, a top hole is opened on the top of the valve body located directly above the filter frame body, a vertical rod is fixedly connected to the top of the filter frame body, and a cover plate located outside the valve body is fixedly connected to the top of the vertical rod, and the cover plate is limited on the valve body by a pressing assembly.

[0006] Optionally, the pressing assembly includes a screw, which is rotatably connected to the top of the valve body. A crossbar is threaded onto the outer surface of the screw. Side plates are fixedly connected to both sides of the crossbar. Fixing blocks are fixedly installed on both sides of the valve body. A guide rod is fixedly connected to the bottom of the side plate. The bottom of the guide rod passes through the fixing block. Two pressure plates are provided between the two side plates.

[0007] Optionally, a groove is provided on the side plate, and the pressure plate is slidably connected to the inner wall of the groove.

[0008] Optionally, the valve gate assembly includes a valve cover, which is fixedly mounted on the valve body. A bracket is fixedly mounted on the valve cover, and a valve stem is threaded onto the bracket. A handwheel is fixedly connected to the top of the valve stem, and a gate plate is fixedly connected to the bottom of the valve stem inside the valve body.

[0009] Optionally, a sealing gasket located outside the top hole is fixedly installed on the top of the valve body, and the top of the sealing gasket abuts against the bottom of the cover plate.

[0010] Optionally, flanges are fixedly installed on both sides of the valve body, and through holes are uniformly opened on the surface of the flanges.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by setting up a vertical rod, a cover plate, and a pressing assembly, allows workers to remove the filter frame body for cleaning by rotating the screw in the pressing assembly. This causes the horizontal rod to move the side plate and pressure plate upward, thereby releasing the limiting effect on the cover plate. Then, the two pressure plates are moved in opposite directions, making the distance between the two pressure plates greater than the diameter of the cover plate. The cover plate can then be pulled upward, causing the vertical rod to move the filter frame body upward, allowing the filter frame body to be removed for cleaning. This eliminates the need to disassemble the entire valve body from the pipeline, making it convenient, quick, and improving the work efficiency of the workers. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown in the figure, the present invention provides a control valve for a tap water filtration tank, including a valve body 1, a valve gate assembly on the valve body 1, a filter frame body 2 movably installed inside the valve body 1, a top hole 3 located directly above the filter frame body 2 on the top of the valve body 1, a vertical rod 4 fixedly connected to the top of the filter frame body 2, and a cover plate 5 located outside the valve body 1 fixedly connected to the top of the vertical rod 4, the cover plate 5 being limited on the valve body 1 by a pressing assembly.

[0022] Furthermore, the pressing assembly includes a screw 6, which is rotatably connected to the top of the valve body 1. A crossbar 7 is threaded onto the outer surface of the screw 6. Side plates 8 are fixedly connected to both sides of the crossbar 7. Fixing blocks 9 are fixedly installed on both sides of the valve body 1. A guide rod 10 is fixedly connected to the bottom of the side plate 8. The bottom of the guide rod 10 passes through the fixing block 9. Two pressure plates 11 are provided between the two side plates 8.

[0023] By rotating the screw 6, the crossbar 7 can drive the side plate 8 and the pressure plate 11 to move downward, thereby enabling the pressure plate 11 to press down on the cover plate 5, so that the cover plate 5 is held at the top of the valve body 1 to seal the top hole 3.

[0024] Furthermore, a groove 12 is provided on the side plate 8, and the pressure plate 11 is slidably connected to the inner wall of the groove 12.

[0025] When the screw 6 is rotated, the crossbar 7 causes the side plate 8 and the pressure plate 11 to move upward. The two pressure plates 11 can be pushed to move in opposite directions along the slide groove 12, which can make enough space for the cover plate 5. Then the cover plate 5 can be pulled upward to remove the filter frame body 2 from the valve body 1.

[0026] Furthermore, the valve gate assembly includes a valve cover 13, which is fixedly mounted on the valve body 1. A bracket 14 is fixedly mounted on the valve cover 13, and a valve stem 15 is threadedly connected to the bracket 14. A handwheel 16 is fixedly connected to the top of the valve stem 15, and a gate 17 is fixedly connected to the bottom of the valve stem 15 inside the valve body 1.

[0027] By rotating the valve stem 15 with the handwheel 16, the gate 17 can be moved up or down, thereby controlling the flow and shut-off of water in the valve body 1.

[0028] Furthermore, a sealing gasket 18 is fixedly installed on the top of the valve body 1, located outside the top hole 3, with the top of the sealing gasket 18 abutting against the bottom of the cover plate 5.

[0029] The design of the sealing gasket 18 can improve the sealing effect of the cover plate 5 on the top hole 3, preventing water from overflowing from the top hole 3.

[0030] Furthermore, flanges 19 are fixedly installed on both sides of the valve body 1, and through holes 20 are evenly opened on the surface of the flanges 19.

[0031] Workers can easily install the valve body 1 between the two pipes by connecting the pipes through the through hole 20 with bolts.

[0032] Working principle and usage process of this utility model:

[0033] When workers need to disassemble the filter frame body 2 to clean the impurities inside, they can first turn the valve stem 15 by handwheel 16 to move the gate 17 downwards to stop the water flow. Then, they can turn the screw 6 to move the crossbar 7, which in turn moves the side plate 8 and pressure plate 11 upwards, thus releasing the limiting effect on the cover plate 5. Then, they can move the two pressure plates 11 in opposite directions so that the distance between the two pressure plates 11 is greater than the diameter of the cover plate 5. Then, they can pull the cover plate 5 upwards to move the vertical rod 4 upwards, which will allow the filter frame body 2 to be removed for cleaning. This eliminates the need to disassemble the entire valve body 1 from the pipeline, making it convenient and quick, and improving the work efficiency of the workers.

[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
