Description

Technical Field

[0001] This utility model relates to the field of active valve technology, specifically to an active valve filter element structure that is easy to disassemble and assemble. Background Technology

[0002] Active valve filter elements, as core components of industrial fluid control systems, are widely used in hydraulic equipment, lubrication systems, and water treatment devices. Their functions encompass dynamic control such as filtering impurities, regulating flow, and backflushing. In existing technologies, filter element structures mostly employ traditional designs such as threaded connections, flange fixation, or built-in snap-fits. However, as industrial equipment evolves towards compactness and high-frequency maintenance, the limitations of traditional filter elements in terms of disassembly and assembly efficiency, sealing reliability, and modular adaptability are becoming increasingly apparent, becoming key factors restricting the overall performance improvement of the system.

[0003] To ensure filtration performance, existing active valve filter elements often use interference fits or rigid connections between the filter element and the valve body. This necessitates complete disassembly of surrounding piping and valve body components during replacement, which is time-consuming, labor-intensive, and results in prolonged downtime, impacting production efficiency. Therefore, a more convenient active valve filter element structure is proposed. Utility Model Content

[0027] The top of the fixing block 21 is symmetrically provided with threaded holes 23. The inner sidewall of the mounting groove 22 is uniformly fixedly connected with a first sealing strip 24. The top of the fixing block 21 is fixedly connected with a second sealing strip 25. The inside of the slot 26 is engaged with a fixing ring 211. The inner sidewall of the fixing ring 211 is fixedly connected with a filter screen 212. The inside of the mounting groove 22 is provided with a sealing plate 27. The bottom of the sealing plate 27 is symmetrically fixedly connected with a pressure plate 28. The pressure plate 28 is fixedly connected to the fixing block 21 by fixing bolts 29. The inner sidewall of the sealing plate 27 is fixedly connected with a mounting base 210. The fixing ring 211 is engaged with the inner sidewall of the mounting base 210. When the filter element assembly 20 needs to be replaced, the operator loosens the fixing bolts 29 and removes the pressure plate 28 and the sealing plate 27 from the mounting groove 22, exposing the filter screen 212 and the fixing ring 211. Since the retaining ring 211 is secured to the mounting base 210 via the slot 26, operators can easily remove the retaining ring 211 and filter screen 212 from the mounting base 210 for replacement or cleaning. After the new filter screen 212 and retaining ring 211 are reinstalled onto the mounting base 210 via the slot 26, the sealing plate 27 and pressure plate 28 are then secured into the mounting groove 22 using the fixing bolts 29, thus completing the replacement of the filter element assembly 20. The mounting base 210 also has a corresponding mounting groove for installing the retaining ring 211.

[0028] In this embodiment, specifically: an active valve assembly 10 is provided on the outside of the filter element assembly 20, the active valve assembly 10 includes a valve body 11; two fixing blocks 21 are symmetrically fixedly connected to the outer side wall of the valve body 11, and a mounting groove 22 is opened on the top of the valve body 11.

[0029] In this embodiment, specifically: a drive box 12 is fixedly connected to the top of the valve body 11. A drive motor or cylinder is installed inside the drive box 12 to drive the valve core inside the valve body 11 to perform corresponding actions, thereby quickly opening and closing the active valve.
