Description

Technical Field

[0001] This utility model relates to the field of valve filter technology, specifically a valve filter with an easy-to-replace filter screen. Background Technology

[0002] A valve filter is a device that can be directly installed on a pipeline, combining the dual functions of a valve and a filter. Through the physical interception of the filter screen, it effectively filters out impurities in the fluid, such as particulate solids, fibers, and debris, thereby achieving deep filtration and purification of the fluid.

[0003] The existing valve filter screen is located inside the valve filter. When the screen needs to be repaired, the valve filter is fixed by multiple bolts, which require specific tools or skills to remove, thus increasing the complexity of replacing the screen.

[0004] Therefore, this utility model proposes a valve filter that facilitates filter screen replacement to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a valve filter that facilitates filter screen replacement, comprising a valve filter body, a support tube fixedly connected to the outer surface of the valve filter body, a maintenance tube provided at one end of the support tube, a filter screen provided inside the maintenance tube, and further comprising: a quick-release maintenance mechanism.

[0006] Preferably, the quick-release maintenance mechanism includes a plug ring, which is fixedly connected to one end of the maintenance tube. The outer surface of the plug ring is fixedly connected with protrusions at equal intervals, and both the plug ring and the protrusions are inserted into the support tube.

[0007] Preferably, a threaded ring is bolted to the outer surface of the support tube, and a pressure ring is slidably connected to the outer surface of the support tube, with the threaded ring and the pressure ring being rotatably connected.

[0008] Preferably, the outer surface of the insert ring is provided with slots at equal intervals, and the lower end of the pressure ring is set in an arc shape.

[0009] Preferably, the outer surface of the support tube is equidistantly connected with sliding columns, one end of which is fixedly connected to a hemispherical block, and the other end of which is engaged with a slot.

[0010] Preferably, a limiting ring is fixedly connected to the outer surface of the sliding column, and a return spring is fixedly connected between the limiting ring and the support tube, and the limiting ring and the support tube are slidably connected.

[0011] Compared with the prior art, this utility model provides a valve filter that facilitates filter screen replacement, and has the following beneficial effects:

[0012] 1. With the quick-release maintenance mechanism, workers only need to turn the threaded ring to complete the disassembly and installation of the maintenance pipe and support pipe. No tools are required, which reduces the professional skills required of workers, enabling more people to perform the disassembly and installation work. This improves the overall convenience of operation, saves time and costs, simplifies the disassembly and installation process, and reduces the number of steps workers need to take when maintaining or repairing equipment, thereby significantly improving work efficiency.

[0013] 2. The compression of multiple hemispherical blocks can be completed by the downward sliding of the pressure ring, so that multiple sliding columns can be inserted into the slots at the same time. Through the insertion at multiple angles, the fixing effect of the support tube and the maintenance tube after installation is guaranteed, and the stability of its use is improved.

[0023] Embodiments of this utility model

[0024] Please refer to Figures 1 to 4 As shown:

[0025] To address the problems mentioned in the technical solutions, this application provides a valve filter with an easily replaceable filter screen, comprising a valve filter body 1, a support tube 11 fixedly connected to the outer surface of the valve filter body 1, a maintenance tube 12 provided at one end of the support tube 11, a filter screen disposed inside the maintenance tube 12, and a quick-release maintenance mechanism, comprising a insertion ring 301 fixedly connected to one end of the maintenance tube 12, and equidistant protrusions 302 fixedly connected to the outer surface of the insertion ring 301, both the insertion ring 301 and the protrusions 302 being inserted into the support tube 11, and bolts connecting the outer surface of the support tube 11. A threaded ring 303 and a pressure ring 304 are slidably connected to the outer surface of the support tube 11. The threaded ring 303 and the pressure ring 304 are rotatably connected. The outer surface of the insertion ring 301 is provided with slots 305 at equal intervals. The lower end of the pressure ring 304 is set to be arc-shaped. A sliding column 306 is slidably connected through the outer surface of the support tube 11 at equal intervals. One end of the sliding column 306 is fixedly connected to a hemispherical block 307. The other end of the sliding column 306 is engaged with the slot 305. A limit ring 309 is fixedly connected to the outer surface of the sliding column 306. A return spring 308 is fixedly connected between the limit ring 309 and the support tube 11. The limit ring 309 is slidably connected to the support tube 11.

[0026] The working principle of all the content in the above embodiments is as follows:

[0027] When it is necessary to install the inspection pipe 12 and the support pipe 11, insert the insertion ring 301 and the protrusion 302 into the bottom of the support pipe 11, and then rotate the threaded ring 303. Since the threaded ring 303 is threadedly connected to the support pipe 11, the threaded ring 303 is rotatably connected to the pressure ring 304, and the pressure ring 304 is slidably connected to the support pipe 11, when the threaded ring 303 rotates, it will drive the pressure ring 304 to move downward, thereby causing the bottom arc surface of the pressure ring 304 to press against the spherical surface of the hemispherical block 307, pushing the hemispherical block 307 and the sliding column 306 to slide towards the slot 305, thereby causing one end of the sliding column 306 to be inserted into the slot 305, and the return spring 308 to be compressed until the pressure ring 304 completely covers the hemispherical block 307. At this time, the threaded ring 303 stops rotating, and the sliding column 306 completes the engagement with the slot 305, thereby completing the fixation of the support pipe 11 and the inspection pipe 12.

[0028] When the support tube 11 and the inspection tube 12 are disassembled, and the filter screen inside the inspection tube 12 is inspected and replaced, the threaded ring 303 is rotated in the opposite direction, causing the threaded ring 303 to pull the pressure ring 304 upward, thereby causing the pressure ring 304 to disengage from the hemispherical block 307. Then, under the rebound force of the return spring 308, the sliding column 306 is driven to slide away from the slot 305, thereby causing the sliding column 306 to disengage from the slot 305. Then, the inspection tube 12 is pulled downward to complete the separation of the support tube 11 and the inspection tube 12, so that the filter screen inside the inspection tube 12 can be inspected.

[0029] With the quick-release maintenance mechanism, staff only need to rotate the threaded ring 303 to complete the disassembly and installation of the maintenance pipe 12 and the support pipe 11 without the need for tools. This reduces the professional skills required of staff, enabling more people to perform the disassembly and installation work, improving the overall ease of operation, saving time and costs, simplifying the disassembly and installation process, and reducing the number of steps staff need to take during equipment maintenance or repair, thereby significantly improving work efficiency.

[0030] At the same time, the compression of multiple hemispherical blocks 307 can be completed by the downward movement of the pressure ring 304, so that multiple sliding columns 306 can be inserted into the slots 305 at the same time. Through the insertion at multiple angles, the fixing effect of the support tube 11 and the inspection tube 12 after installation is guaranteed, and the stability of their use is improved.
