Description

Technical Field

[0001] This utility model relates to the field of HVAC valves, and in particular to an HVAC valve with a filter structure. Background Technology

[0002] HVAC valves control fluid flow through a ball with a central opening; rotating the ball 90 degrees around its axis opens or closes the valve. They feature low fluid resistance, a simple structure, and good sealing, offering convenient operation and rapid response, making them particularly suitable for scenarios requiring quick fluid shut-off.

[0003] Chinese Patent CN219102143U discloses a HVAC valve with a filter structure, including a valve body and a connecting pipe. Connecting ends are fixedly connected to both sides of the valve body, and fixed ends are fixedly connected to the outer walls of the valve body away from the connecting ends. Several locking mechanisms are fixedly connected inside each fixed end, and a connecting rod is slidably connected inside each locking mechanism. In this invention, pressing the stop block disengages the connecting body from the locking state, rotating the connecting body disengages it from the hook groove, and rotating the connecting pipe disengages the groove of the round rod from the locking block, allowing for easy access to the filter screen and internal parts for maintenance or cleaning. This achieves tool-free disassembly and installation, and the reinforcement device improves stability to a certain extent. However, the aforementioned patent requires the operation of multiple locking mechanisms for cleaning and installation of the filter screen, which is cumbersome. Furthermore, the use of multiple locking mechanisms makes it difficult to securely seal the pipe connections, leading to potential water leakage. Therefore, we propose an HVAC valve with a filter structure to solve these problems. Utility Model Content

An inlet pipe is fixedly connected to the outer surface of the filter housing, and a connecting assembly is provided on the outside of the inlet pipe. A filter cylinder is provided inside the filter housing, and an annular filter screen is embedded on the outer surface of the filter cylinder. A threaded sealing seat is fixedly connected to the outer surface of the filter housing, and a threaded sealing cover is threadedly connected to the inner wall of the threaded sealing seat. The inner bottom wall of the threaded sealing cover is connected to the bottom end of the filter cylinder, and a hexagonal block is fixedly connected to the bottom surface of the threaded sealing cover.

[0007] In a further embodiment, the connecting assembly includes a threaded connector fixedly connected to the outer surface of the water inlet pipe, one end of the water inlet pipe is provided with a water delivery pipe, and an annular limiting plate is fixedly connected to the outer surface of the water delivery pipe.

[0008] In a further embodiment, the inner wall of the threaded connector is threaded with a threaded connector cover, and the outer surface of the threaded connector cover is provided with two rotating protrusions. The inner wall of the threaded connector and one side of the annular limiting plate are respectively provided with a first sealing gasket and a second sealing gasket. One side of the first sealing gasket and one side of the second sealing gasket are in contact with the outer surface of the threaded connector cover.

[0009] In a further embodiment, the inner ring of the water inlet pipe is fixedly connected to a threaded connecting ring, and the inner ring of the threaded connecting ring is threadedly connected to a circular filter plate.

[0010] In a further embodiment, the inner top wall of the filter housing is connected to an annular buffer pad, and the top of the filter cylinder is in contact with the bottom surface of the annular buffer pad.

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

[0012] This utility model utilizes a threaded connector on the inlet pipe, which, in conjunction with an external annular limiting plate and threaded connector cover on the water delivery pipe, allows for a quick and sealed connection between the water delivery pipe and the inlet pipe by screwing the threaded connector cover into the threaded connector. The circular filter plate and annular filter screen enable two-stage filtration of the flowing medium, improving filtration efficiency. Furthermore, when cleaning the filter assembly, rotating the hexagonal block downwards to rotate the threaded sealing cover allows for easy removal of the filter cylinder from the filter housing, facilitating cleaning of the annular filter screen. Simultaneously, the circular filter plate can be removed from the bottom of the filter housing for easy cleaning or replacement, enhancing the flexibility of cleaning the filter assembly.

The inner bottom wall of the threaded sealing cover 10 is connected to the bottom end of the filter cylinder 8. A hexagonal block 11 is fixedly connected to the bottom surface of the threaded sealing cover 10. The cooperation between the threaded sealing seat 9 and the threaded sealing cover 10 facilitates the installation and sealing of the filter cylinder 8. The hexagonal block 11 improves the flexibility of the threaded sealing cover 10 when rotating. In addition, a sealing gasket is installed inside the threaded sealing seat 9 to seal the connection between the threaded sealing seat 9 and the threaded sealing cover 10.

[0022] In a further embodiment, the connecting assembly 5 includes a threaded connecting seat 501 fixedly connected to the outer surface of the water inlet pipe 4. One end of the water inlet pipe 4 is provided with a water supply pipe 6. An annular limiting plate 503 is fixedly connected to the outer surface of the water supply pipe 6. A threaded connecting cover 502 is threadedly connected to the inner wall of the threaded connecting seat 501. Two rotating protrusions 506 are provided on the outer surface of the threaded connecting cover 502. A first sealing gasket 505 and a second sealing gasket 504 are respectively provided on the inner wall of the threaded connecting seat 501 and one side of the annular limiting plate 503.

The circular filter plate 13 can be installed by setting the threaded connecting ring 12. The installation of the circular filter plate 13 will enhance the filtration effect of the valve. The annular buffer pad 14 can buffer the top of the filter cylinder 8 during installation and enhance the sealing effect between the filter cylinder 8 and the inner wall of the filter shell 3.

[0024] The working principle of this utility model is as follows: First, water flows from the water supply pipe 6 through the connecting component 5 into the water inlet pipe 4. After entering the water inlet pipe 4, the water is initially filtered by the circular filter plate 13. Then, the water flows into the filter shell 3, where the annular filter screen 7 embedded on the outer surface of the filter cylinder 8 can further filter the water. When disassembling and cleaning the filter cylinder 8, the threaded sealing cover 10 can be rotated downwards by rotating the hexagonal block 11, which will drive the filter cylinder 8 to be disassembled from the inside of the filter shell 3. Then, the annular filter screen 7 on the surface of the filter cylinder 8 can be cleaned, and the circular filter plate 13 can be removed from the bottom of the filter shell 3, making it easier to clean or replace. When installing the filter cylinder 8, the threaded sealing cover 10 can be screwed into the threaded sealing seat 9 by rotating the hexagonal block 11, which can fix the filter cylinder 8 inside the filter shell 3.
