Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a filter gate valve. Background Technology

[0002] A gate valve is a gate that opens and closes. The direction of the gate's movement is perpendicular to the direction of the fluid. Gate valves can only be fully open or fully closed, and cannot be used for regulation or throttling. To avoid clogging problems, existing gate valves usually have a filter structure installed on them, so that impurities in the water flowing through the gate valve can be filtered out.

[0003] For example, an existing patent (publication number: CN220168623U) discloses a filter gate valve in which water flows into the valve body after passing through the filter box. The water is filtered by the first filter plate and the second filter plate respectively. Larger impurities are filtered through the first filter hole and smaller impurities are filtered through the second filter hole, thereby improving the filtration efficiency.

[0004] However, the above-designed filter gate valve still has some drawbacks in actual use: Although the filter gate valve can filter the water flow through the first filter plate and the second filter plate respectively, filtering larger impurities through the first filter hole and smaller impurities through the second filter hole, thereby improving the filtration efficiency, the impact force generated by the water flow when the valve is opened is too large, which not only makes it easy to wash and deform the filter screen, but also makes it easy to loosen the connection between the filter screen and the valve, thus accelerating the damage to the filter screen.

[0005] To address this issue, we designed a filter gate valve. Utility Model Content

[0006] The purpose of this invention is to provide a filter gate valve to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a filter gate valve, including a gate valve body, a filter box provided on one side of the gate valve body, connecting pipes fixedly inserted on both sides of the filter box, one of the connecting pipes being connected to the gate valve body, a fixing component fixedly installed inside the filter box, a flow guide port opened in the fixing component, a filter screen slidably arranged inside the filter box, two sliders symmetrically slidably arranged inside the fixing component, a rotating component rotatably arranged between the sliders and the filter screen, and a buffer component provided on the opposite side of the two sliders.

[0008] Furthermore, there are two flow guide ports, and the two flow guide ports are symmetrically opened in the fixing member.

[0009] Furthermore, a limiting groove is formed at the center of one side of the fixing member, and the two sliders are symmetrically slidably inserted into the limiting groove. The buffer member includes a spring and a damping cylinder. The two ends of the spring and the damping cylinder are respectively fixedly installed between the inner wall of the limiting groove and the slider, and the spring is movably sleeved on the damping cylinder.

[0010] Furthermore, a mounting base is fixedly installed on one side of the slider, a fixing base is fixedly installed at the center of one side of the filter screen, and the two ends of the rotating component are respectively rotatably disposed in the mounting base and the fixing base.

[0011] Furthermore, a first pin is provided in the mounting base, a second pin is provided in the fixed base, and the two ends of the rotating component are respectively rotatably sleeved on the first pin and the second pin.

[0012] Furthermore, a support base is fixedly installed between the two rotating parts, and a telescopic rod is rotatably arranged between the two support bases. A third pin is provided inside each of the two support bases, and the two ends of the telescopic rod are respectively rotatably sleeved on the two third pins.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: when water flows over the filter screen, the filter screen will slide inside the filter box. During this process, the rotating part will rotate and push the two sliders away from each other in the limiting groove. At the same time, the spring will be compressed and absorb the impact force. After the water flow is stable, the damping cylinder can make the spring slowly rebound, which can make the filter screen achieve a buffering effect, avoid accelerating the deformation of the filter screen, and thus help extend the service life of the filter screen.

[0014] Compared with the prior art, the beneficial effects of this utility model are: when the included angle between the two rotating parts increases, the telescopic end of the telescopic rod will be stretched and the telescopic rod will rotate slightly, which can increase the stability of the rotation between the two rotating parts, thereby helping to solve the problem of the rotating parts breaking.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a filter gate valve, including a gate valve body 1, a filter box 2 is provided on one side of the gate valve body 1, and connecting pipes 3 are fixedly inserted on both sides of the filter box 2. One of the connecting pipes 3 is connected to the gate valve body 1. A fixing member 4 is fixedly installed inside the filter box 2. A flow guide port 5 is opened in the fixing member 4. A filter screen 6 is slidably arranged inside the filter box 2. Two sliders 7 are symmetrically slidably arranged inside the fixing member 4. A rotating member 8 is rotatably arranged between the sliders 7 and the filter screen 6. A buffer member is provided on the opposite side of the two sliders 7.

[0024] A limiting groove 11 is opened at the center of one side of the fixing part 4. Two sliders 7 are symmetrically slidably inserted into the limiting groove 11. The buffer part includes a spring 9 and a damping cylinder 10. The two ends of the spring 9 and the damping cylinder 10 are respectively fixedly installed between the inner wall of the limiting groove 11 and the slider 7. The spring 9 is movably sleeved on the damping cylinder 10.

[0025] A mounting base 12 is fixedly installed on one side of the slider 7, and a fixed base 13 is fixedly installed at the center of one side of the filter screen 6. The two ends of the rotating part 8 are respectively rotatably set in the mounting base 12 and the fixed base 13. A first pin is provided in the mounting base 12, and a second pin is provided in the fixed base 13. The two ends of the rotating part 8 are respectively rotatably sleeved on the first pin and the second pin.

[0026] In practical implementation, when water flows over the filter screen 6, the filter screen 6 will slide inside the filter box 2. During this process, the rotating part 8 will rotate and push the two sliders 7 away from each other in the limiting groove 11. At the same time, the spring 9 will be compressed and absorb the impact force. After the water flow stabilizes, the damping cylinder 10 can make the spring 9 slowly rebound, which can make the filter screen 6 achieve a buffering effect, avoid accelerating the deformation of the filter screen 6, and thus help extend the service life of the filter screen 6.

[0027] See Figure 1-4 There are two flow guide ports 5, and the two flow guide ports 5 are symmetrically opened inside the fixing member 4. The setting of two flow guide ports 5 can increase the flow rate of water inside the fixing member 4, thereby avoiding the problem of insufficient water flow.

[0028] See Figure 1-4 A support base 14 is fixedly installed between the two rotating parts 8. A telescopic rod 15 is rotatably arranged between the two support bases 14. A third pin is provided inside each of the two support bases 14. The two ends of the telescopic rod 15 are respectively rotatably sleeved on the two third pins.

[0029] In specific implementation, based on the above implementation, when the included angle between the two rotating parts 8 increases, the telescopic end of the telescopic rod 15 will be stretched and the telescopic rod 15 will rotate slightly, which can increase the stability of the rotation between the two rotating parts 8, thereby helping to solve the problem of the rotating parts 8 breaking.

[0030] Working principle: When in use, as water flows over the filter screen 6, the filter screen 6 will slide inside the filter box 2. During this process, the rotating part 8 will rotate and push the two sliders 7 away from each other in the limiting groove 11. At the same time, the spring 9 will be compressed and absorb the impact force. After the water flow stabilizes, the damping cylinder 10 will make the spring 9 slowly rebound, which can make the filter screen 6 achieve a buffering effect, avoid accelerating the deformation of the filter screen 6, and thus help extend the service life of the filter screen 6.

[0031] During the above operation, when the included angle between the two rotating parts 8 increases, the telescopic end of the telescopic rod 15 will be stretched and the telescopic rod 15 will rotate slightly, which can increase the stability of the rotation between the two rotating parts 8, thereby helping to solve the problem of the rotating parts 8 breaking.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
