[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 - Figure 3 , an embodiment provided by the present utility model: a high-pressure and corrosion-resistant valve, including a valve body 1, a connecting pipe 2 is fixedly connected to the side wall of the valve body 1, a fixed block 3 is fixedly connected to the side wall of the connecting pipe 2, a concave hole 4 is opened inside the fixed block 3, a plug rod 5 is arranged inside the fixed block 3, the plug rod 5 is slidably connected inside the concave hole 4, a horizontal hole 6 is opened inside the plug rod 5, a fixed plate 7 is fixedly connected to the side wall of the connecting pipe 2, a clamping column 8 is slidably connected inside the fixed plate 7, a limit block 9 is fixedly connected to the side wall of the clamping column 8, a pull ring 10 is fixedly connected to the side wall of the limit block 9, a first spring 11 is sleeved on the side wall of the clamping column 8, one end of the first spring 11 is fixedly connected to the side wall of the fixed plate 7, and the other end of the first spring 11 is fixedly connected to the side wall of the limit block 9, the clamping column 8 is slidably connected inside the horizontal hole 6, a sealing component is arranged inside the connecting pipe 2, and the sealing component is used to prevent liquid leakage. The sealing component includes a sealing ring 12, and the side wall of the sealing ring 12 is fixedly connected inside the connecting pipe 2;

[0032] When using this device, when it is necessary to connect the connecting pipe 2, the pull ring 10 is pulled to move the clamping post 8, which slides inside the fixing plate 7. During the sliding process of the clamping post 8, the first spring 11 is compressed, causing it to be under pressure and contract. Then, the insertion rod 5 is inserted into the concave hole 4 opened inside the fixing block 3. After completing this step, the pull ring 10 is released. At this time, since the first spring 11 loses pressure, it will reset. During the reset process, the clamping post 8 will be pushed by the first spring 11 and then inserted into the inside of the horizontal hole 6, thereby fixing the insertion rod 5. Through such an operation, the rapid connection of the connecting pipe 2 can be achieved. When it is necessary to disassemble and repair the connecting pipe 2, the pull ring 10 is pulled to slide the clamping post 8, thereby canceling the fixed state of the insertion rod 5, and the insertion rod 5 is pulled out from the concave hole 4 of the fixing block 3. In this way, the fixation of the fixing block 3 is canceled, and the connection between the connecting pipes 2 is canceled, facilitating maintenance.

[0033] Refer to Figure 2 As shown in the figure, a filter cartridge 13 is provided inside the connecting pipe 2. A connecting ring 14 is fixedly connected to the side wall of the filter cartridge 13. An insertion hole 15 is opened inside the connecting ring 14. A fixing frame 16 is fixedly connected to the side wall of the connecting pipe 2. A sliding rod 17 is fixedly connected inside the fixing frame 16. A clamping block 18 is slidably connected inside the fixing frame 16. The clamping block 18 is slidably connected to the side wall of the sliding rod 17. A second spring 19 is sleeved on the side wall of the sliding rod 17. A connecting block 20 is fixedly connected to the side wall of the clamping block 18. A connecting plate 21 is rotatably connected inside the connecting block 20. A button 22 is rotatably connected to the side wall of the connecting plate 21. One end of the second spring 19 is fixedly connected inside the fixing frame 16, and the other end of the second spring 19 is fixedly connected to the side wall of the clamping block 18. The side wall of the clamping block 18 is slidably connected inside the insertion hole 15, and the side wall of the button 22 is slidably connected inside the fixing frame 16.

[0034] During the installation process of the filter cartridge 13, first, the button 22 is pressed to squeeze it inward, causing the connecting plate 21 to rotate inside the connecting block 20. As the connecting plate 21 rotates, the clamping block 18 also moves accordingly. The movement of the clamping block 18 exerts pressure on the second spring 19, causing it to contract. As the second spring 19 contracts, the clamping block 18 enters the inside of the fixing frame 16. At this time, the filter cartridge 13 is placed inside the connecting pipe 2. After completing this step, the button 22 is released. The second spring 19 will lose the pressure exerted on it by the clamping block 18 and thus rebound. The rebound of the second spring 19 will push the clamping block 18 to insert into the inside of the insertion hole 15, thereby realizing the fixation of the filter cartridge 13. When the filter cartridge 13 needs to be cleaned, the button 22 is pressed again, causing the connecting plate 21 to rotate and drive the clamping block 18 to move. At this time, the second spring 19 will contract again, and the clamping block 18 will enter the inside of the fixing frame 16, thereby canceling the fixation of the filter cartridge 13. Finally, the filter cartridge 13 is pulled out through the connecting ring 14 for cleaning.

[0035] Working principle: When using this device, when connecting the connecting pipes 2, the clamping post 8 is pulled to slide by the pull ring 10. When the clamping post 8 slides, the first spring 11 is compressed and contracts. Then, the insertion rod 5 is inserted into the concave hole 4 opened inside the fixed block 3. Then, the pull ring 10 is released. At this time, the first spring 11 loses pressure and resets, so that the clamping post 8 is inserted into the transverse hole 6 to fix the insertion rod 5, completing the quick connection of the connecting pipes 2. When disassembling and repairing the connecting pipes 2, the pull ring 10 is pulled to make the clamping post 8 slide, cancel the fixation of the insertion rod 5, and pull out the insertion rod 5 to cancel the fixation of the fixed block 3, so that the connecting pipes 2 are separated and the connection between them is cancelled.

[0036] When installing the filter cartridge 13, it is pressed inward by pressing the button 22, so that the connecting plate 21 rotates inside the connecting block 20, driving the clamping block 18 to move. The movement of the clamping block 18 compresses the second spring 19 to make it contract, so that the clamping block 18 enters the inside of the fixed frame 16. After the filter cartridge 13 is placed inside the connecting pipe 2, the button 22 is released, so that the second spring 19 loses the extrusion of the clamping block 18 on it and rebounds, so that the second spring 19 pushes the clamping block 18 to insert into the jack 15 for fixation. When it is necessary to clean the filter cartridge 13, press the button 22 to make the connecting plate 21 rotate to drive the clamping block 18 to move, so that the second spring 19 contracts, and the clamping block 18 enters the inside of the fixed frame 16 to cancel the fixation of the filter cartridge 13, and it is pulled out through the connecting ring 14 for cleaning.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
