Description

Technical Field

[0001] This utility model relates to the field of valve device technology, and in particular to a valve filter device that facilitates the cleaning of impurities. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shutting off, regulating, guiding, preventing backflow, stabilizing pressure, diverting flow, or overflowing and relieving pressure. They are used to change the cross-sectional area of ​​the passage and the direction of medium flow, and have functions such as guiding, shutting off, throttling, checking flow, diverting flow, or overflowing and relieving pressure.

[0003] Referring to the public announcement number CN222056649U, this utility model provides a valve filter device, belonging to the technical field of filter devices. It includes a round tube and a filter pipe. The top surface of the filter pipe has a slot, and the bottom of the inner wall of the filter pipe has a groove. A filter component is installed in the slot and the groove. The bottom of the filter pipe is connected to a dirt storage component. In the above solution, the filter component is used to filter impurities. However, when cleaning impurities, the filter component needs to be moved upward. During the removal process, impurities are easily dropped from the filter component due to the disturbance of the flow. The dropped debris can easily cause blockage inside the valve, which is not practical. Therefore, it is necessary to redesign a valve filter device that is easy to clean impurities to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a valve filter device that facilitates the removal of impurities.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A valve filter device for easy cleaning of impurities includes a valve body, a filter box fixedly installed at the inlet of the valve body, a filter housing slidably installed on the upper surface of the filter box through a movable opening, a baffle rotatably installed on the inner wall of the filter housing through a rotating mechanism, a first connecting frame fixedly installed on the bottom wall of the baffle, a sliding rod slidably installed inside the filter housing through a sliding groove, a sliding sleeve slidably installed on the outer wall of the sliding rod, the upper surface of the sliding sleeve being connected to the inner wall of the sliding groove through an elastic mechanism, a second connecting frame fixedly installed on the outer wall of the sliding sleeve, a connecting plate rotatably installed inside the second connecting frame, the end of the connecting plate being rotatably connected to the inside of the first connecting frame, a sealing plate fixedly installed on the upper surface of the filter housing, and two compression bolts rotatably installed on the upper surface of the filter housing through a support mechanism, the ends of both compression bolts being rotatably installed with compression plates through a connecting mechanism.

[0007] Preferably, the rotating mechanism includes a rotating shaft rotatably mounted inside the filter box, the rotating shaft rotating through the baffle.

[0008] Preferably, the elastic mechanism includes a spring installed on the outer wall of the slide rod, with both ends of the spring elastically connected to the inner wall of the slide groove and the upper end face of the slide sleeve, respectively.

[0011] Preferably, a sealing gasket is fixedly installed on the bottom wall of the sealing plate, and the sealing gasket is made of vulcanized rubber.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as baffles, sliding rods and sliding sleeves, the inner wall of the moving opening can squeeze the baffle during the process of lifting the filter box, and the sliding sleeve can slide on the outer wall of the sliding rod and pull the spring, thereby keeping the baffle in a closed state, thus preventing impurities from falling out during the upward lifting of the filter box.

[0014] 2. By setting up components such as extrusion bolts, connecting blocks, and extrusion plates, tightening the two extrusion bolts can cause the extrusion bolts to move the extrusion plate through the cooperation of the connecting blocks. This allows the extrusion plate to extrude force against the sealing plate. At this time, the sealing plate can seal the moving opening through the sealing gasket to prevent fluid leakage.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A valve filter device for easy cleaning of impurities includes a valve body 1, a filter box 2 fixedly installed at the inlet of the valve body 1, a filter box 3 slidably installed on the upper surface of the filter box 2 through a movable opening, a baffle 5 rotatably installed on the inner wall of the filter box 3 through a rotating mechanism, the rotating mechanism including a rotating shaft 4 rotatably installed inside the filter box 3, the rotating shaft 4 rotatably passing through the baffle 5, a first connecting frame 6 fixedly installed on the bottom wall of the baffle 5, a slide rod 7 slidably installed inside the filter box 3 through a slide groove, a slide sleeve 8 slidably installed on the outer wall of the slide rod 7, the upper surface of the slide sleeve 8 being connected to the inner wall of the slide groove through an elastic mechanism, the elastic mechanism including a spring 9 installed on the outer wall of the slide rod 7, the two ends of the spring 9 being elastically connected to the inner wall of the slide groove and the upper surface of the slide sleeve 8 respectively.

[0023] A second connecting frame 10 is fixedly installed on the outer wall of the sliding sleeve 8. A connecting plate 11 is rotatably installed inside the second connecting frame 10. The end of the connecting plate 11 is rotatably connected to the inside of the first connecting frame 6. A sealing plate 12 is fixedly installed on the upper surface of the filter box 3. A sealing gasket 13 is fixedly installed on the bottom wall of the sealing plate 12. The sealing gasket 13 is made of vulcanized rubber. Two extrusion bolts 15 are rotatably installed on the upper surface of the filter box 2 through a support mechanism. The support mechanism includes a support plate 14 fixedly installed on the upper surface of the filter box 2. The extrusion bolts 15 pass through the support plate 14 through the thread. Extrusion plates 17 are rotatably installed on the ends of the two extrusion bolts 15 through a connecting mechanism. The connecting mechanism includes a connecting block 16 fixedly installed on the ends of the extrusion bolts 15. The bottom wall of the connecting block 16 is fixedly connected to the upper surface of the extrusion plate 17.

[0024] In use, the baffle 5 can be pressed inward to close it. Then, the filter box 2 can be inserted into the filter box 3 through the movable opening. At this time, the spring 9 retracts, causing the sliding sleeve 8 to slide on the outer wall of the sliding rod 7. The sliding sleeve 8 then moves the second connecting frame 10. The second connecting frame 10, through the cooperation of the connecting plate 11 and the first connecting frame 6, causes the baffle 5 to rotate and tilt (e.g., ...). Figure 1(as shown in the figure), thereby allowing the baffle 5 to release its obstruction of the filter box 3, avoiding affecting the flow of fluid, thus completing the installation of the filter box 3 inside the filter box 2.

[0025] At the same time, the two compression bolts 15 can be turned, which allows the compression bolts 15 to move the compression plate 17 through the cooperation of the connecting block 16. This allows the compression plate 17 to compress the sealing plate 12. At this time, the sealing plate 12 can seal the moving opening through the sealing gasket 13. When it is necessary to remove the filter box 3 to clean the impurities collected by the cleaner, the compression bolts 15 can be turned in the opposite direction, which allows the compression plate 17 to move upward and release the fixing of the sealing plate 12. Then, the compression plate 17 can be rotated through the cooperation of the connecting block 16 (e.g., Figure 1 (as shown in the diagram), thus preventing the squeezing plate 17 from obstructing the sealing plate 12. Next, the filter box 3 can be removed through the movable opening. During this process, the inner wall of the movable opening can squeeze the baffle 5, causing the sliding sleeve 8 to slide on the outer wall of the sliding rod 7 and pull the spring 9. This keeps the baffle 5 in a closed state, preventing impurities from falling out during the upward pulling of the filter box 3. When the filter box 3 is completely pulled out, the baffle 5 can open (as shown in the diagram). Figure 1 (as shown in the image), and then the impurities inside filter box 3 can be cleaned.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
