Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 7 The gas valve structure shown includes:

[0027] The valve body 1 has an integrally connected air outlet 2 at one end. The outer end of the air outlet 2 is machined with external threads. The other end of the air outlet 2 is connected to a filter frame 3. A connecting end 4 is connected to one side of the filter frame 3. The inner end of the connecting end 4 is machined with internal threads.

[0028] The mounting cavity 5 is located at the top of the filter frame 3. A sealing gasket 6 is fixedly installed on the inner wall of the mounting cavity 5. Two clamping plates 7 are provided inside the sealing gasket 6. Clamping grooves 8 are provided inside the clamping plates 7. Activated carbon filter plates 9 are installed inside the two clamping grooves 8. A connecting plate 10 is provided at the top of the two clamping plates 7. The bottom end of the connecting plate 10 contacts the top edge of the sealing gasket 6. First connecting ports 11 are provided on both sides of the sealing gasket 6. Second connecting ports 12 are provided on the outer side of the clamping plates 7. The first connecting ports 11 and the second connecting ports 12 are connected to the valve body 1 and the connecting end 4. A T-shaped slide groove 13 is provided at the bottom of the connecting plate 10. Two T-shaped sliders 14 are provided inside the T-shaped slide groove 13. The bottom ends of the two T-shaped sliders 14 are fixedly connected to the top of the two clamping plates 7 respectively. A handle 15 is fixedly installed at the top of the connecting plate 10.

[0029] The filter frame 3 is provided with an L-shaped limiting plate 16 at both the front and rear ends. One end of the horizontal part of the L-shaped limiting plate 16 passes through the filter frame 3 and extends to the top of the connecting plate 10. The bottom surface of the horizontal part of the L-shaped limiting plate 16 is an arc surface. A threaded rod 17 is rotatably connected to both the front and rear ends of the filter frame 3. One end of the threaded rod 17 passes through the vertical part of the L-shaped limiting plate 16 and extends to the outside of the L-shaped limiting plate 16. The threaded rod 17 and the vertical part of the L-shaped limiting plate 16 are connected by threads. A rotating block 18 is fixedly provided at one end of the threaded rod 17.

[0030] Connect end 4 to the gas inlet pipe and end 2 to the gas outlet pipe. The gas enters the valve body 1 and end 2 after being filtered by activated carbon filter plate 9. This ensures that the gas will not contain impurities or contaminants after entering the gas outlet pipe. After the activated carbon filter plate 9 has been used for a period of time, rotate the rotating block 18. The rotating block 18 drives the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the L-shaped limiting plate 16, the L-shaped limiting plate 16 moves outward with the rotation of the threaded rod 17. The lateral part of the L-shaped limiting plate 16 moves away from the top of the connecting plate 10. Pull the handle 15 upward. The handle 15 drives the connecting plate 10 and the two clamping plates 7 to move upward. The two clamping plates 7 drive the activated carbon filter plate 9 away from the inside of the sealing gasket 6, separating the two clamping plates 7. This allows the activated carbon filter plate 9 to be removed from the clamping groove 8 between the two clamping plates 7, and then the activated carbon filter plate 9 can be replaced and cleaned. After replacement, the two clamping plates 7 are put together and then pressed into the inside of the sealing gasket 6. When the bottom end of the connecting plate 10 is close to the outer edge of the top end of the sealing gasket 6, the rotating block 18 and the threaded rod 17 are rotated in the opposite direction. The arc surface of the L-shaped limiting plate 16 will squeeze the top end of the connecting plate 10. As the L-shaped limiting plate 16 moves to the top end of the connecting plate 10, the connecting plate 10 will press the sealing gasket 6 tightly, thus ensuring the sealing performance.

[0031] This invention uses an activated carbon filter plate 9 to filter impurities and contaminants from gas, reducing the likelihood of damage to gas-powered appliances. The activated carbon filter plate 9 is movably installed inside the clamping groove 8 between two clamping plates 7, and the clamping plates 7 and connecting plate 10 are detachably fixed inside the mounting cavity 5. This makes the installation and removal of the activated carbon filter plate 9 simple and convenient, and also makes cleaning and replacement of the activated carbon filter plate 9 quick and easy, resulting in better performance. This embodiment specifically solves the problem in the prior art where gas valves, due to the presence of impurities and contaminants in the gas, can affect the lifespan of gas-powered appliances. Therefore, some gas valves have a filter structure at the valve inlet, but this filter structure is mostly directly fixed inside the valve inlet, making replacement and cleaning of the filter structure cumbersome.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
