Description

Technical Field

[0001] This utility model relates to the field of diaphragm valve technology, specifically a diaphragm protection device for a diaphragm valve. Background Technology

[0002] Diaphragm valves, a type of gas valve, are a new type of safety accessory for gas pipeline engineering. They are devices made up of pipes, pipe fittings, and valves, used to transport gases, liquids, or fluids containing solid particles. They can be used for air transport, supplying air to indoor areas, and for cutting off, connecting, and regulating gas in pipelines. They have good control characteristics and sealing performance, and are suitable for pipelines carrying various gas media such as city gas, liquefied petroleum gas, natural gas, and oxygen. Gas valves are regulating tools used to control and adjust the flow rate.

[0003] Existing patent CN220320373U proposes a diaphragm protection device for a diaphragm valve, including a diaphragm valve body, a valve filter screen, and a fixing ring. The valve filter screen has an overall cylindrical structure and is installed at one end of the diaphragm valve body, with the entire screen inside the diaphragm valve body and locked in place by the fixing ring. This utility model purifies the air by setting a filter screen at the end of the diaphragm valve.

[0004] However, the inner membrane protection device of this diaphragm valve still has some defects. During use, the effect of filtering air or liquid by a single filter screen is not good. At the same time, the filter screen is not easy to filter and intercept small metal debris, which can easily lead to diaphragm damage and affect the protection effect of the diaphragm.

[0005] Based on this, a diaphragm valve inner diaphragm protection device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-4 As shown, a diaphragm valve inner membrane protection device includes a first threaded ring 1, two first actuating blocks 11 are installed on both sides of one side of the first threaded ring 1, a first limiting ring 12 is installed inside the first threaded ring 1, and a first filter cartridge 13 is installed on the other side of the first threaded ring 1.

[0029] The first threaded ring 1 has a connecting assembly internally threadedly connected to it. The connecting assembly includes a second threaded ring 2, which is threadedly connected to the inside of the first threaded ring 1. Two second actuating blocks 21 are installed on both sides of one side of the second threaded ring 2, and a support rod 22 is installed inside the second threaded ring 2.

[0030] An adsorption component is installed in the middle of one side of the support rod 22;

[0031] The outer thread of the first threaded ring 1 is connected to a filter assembly.

[0032] In this embodiment, the first filter cartridge 13 is supported by the first threaded ring 1. The aperture of the first filter cartridge 13 is larger than that of the second filter cartridge 33, which facilitates secondary filtration of liquids and gases, improves the filtration effect, and avoids the problem of debris damaging the diaphragm. The support rod 22 is fixed by the threaded connection between the second threaded ring 2 and the first threaded ring 1. The second actuating block 21 facilitates the rotation of the second threaded ring 2.

[0033] In one embodiment, such as Figure 1 and Figure 3 As shown, the adsorption assembly includes a connecting column 23, which is installed in the middle of one side of the support rod 22. A support plate 24 is installed on one side of the connecting column 23, and a strong magnetic block 25 is installed in the middle of one side of the support plate 24. The connecting column 23 supports the support plate 24, and the support plate 24 supports the strong magnetic block 25. The strong magnetic block 25 adsorbs and filters metal debris.

[0034] In one embodiment, such as Figure 1 and Figure 3 As shown, a cleaning component is slidably connected to the outer layer of the strong magnetic block 25. The cleaning component wraps the outside of the strong magnetic block 25, avoiding the problem of metal fragments adsorbing onto the strong magnetic block 25 and making it difficult to clean.

[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, the cleaning assembly includes a cleaning sleeve 26, which is slidably connected to the outside of a strong magnetic block 25. An iron sheet 27 is installed inside the cleaning sleeve 26, and the iron sheet 27 is magnetically connected to the strong magnetic block 25. The cleaning sleeve 26 wraps around the outside of the strong magnetic block 25, and the iron sheet 27 is fixed to the strong magnetic block 25 by magnetic attraction, thereby fixing the cleaning sleeve 26.

[0036] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the filter assembly includes a third threaded ring 3, which is threaded to the outside of the first threaded ring 1. Two third actuating blocks 31 are installed on both sides of one side of the third threaded ring 3. A second limiting ring 32 is installed inside the third threaded ring 3. A second filter cartridge 33 is installed on the other side of the third threaded ring 3. Liquids and gases are filtered through the second filter cartridge 33. The third actuating blocks 31 facilitate the rotation of the third threaded ring 3.

[0037] In one embodiment, such as Figure 1 and Figure 4 As shown, the outer thread of the third threaded ring 3 is connected to a valve body assembly.

[0038] In one embodiment, such as Figure 1 and Figure 4 As shown, the valve body assembly includes a connecting ring 34, which is threaded to the outside of the third threaded ring 3. A diaphragm valve body 35 is installed on the outside of the connecting ring 34. The third threaded ring 3 is connected and fixed by the threaded connection between the connecting ring 34 and the third threaded ring 3.

[0039] The above embodiment discloses a diaphragm protection device for a diaphragm valve. A third threaded ring 3 is threadedly connected to a connecting ring 34 to install the third threaded ring 3. A third actuating block 31 facilitates rotation of the third threaded ring 3 for threaded connection. The third threaded ring 3 supports the second filter cartridge 33. A first threaded ring 1 is threadedly connected to the third threaded ring 3, and a second limiting ring 32 provides a limit, facilitating the installation of the first filter cartridge 13. A first actuating block 11 facilitates rotation of the first threaded ring 1, improving the device's convenience and detachability. A second threaded ring 2 is threadedly connected to the inner side of the first threaded ring 1, and a first limiting ring 12 provides a limit, facilitating the installation of the second threaded ring 2. The second actuating block 21 facilitates rotation of the second threaded ring 2. The support rod 22 supports the connecting column 23, and the strong magnetic block 25 is supported by the support plate 24 on one side of the connecting column 23. The cleaning sleeve 26 is slidably connected to the outer layer of the strong magnetic block 25. The cleaning sleeve 26 is quickly installed by magnetic attraction between the iron sheet 27 and the strong magnetic block 25. The magnetic attraction of the strong magnetic block 25 penetrates the cleaning sleeve 26 to magnetically absorb and collect metal debris in the liquid or gas, so as to filter the metal debris in the gas or liquid and avoid the problem of damaging the diaphragm by entering the diaphragm valve body 35. The larger aperture of the first filter cartridge 13 filters larger impurities and debris, and the smaller aperture of the second filter cartridge 33 filters smaller impurities and debris, which improves the filtration effect of the device, avoids the problem of debris and impurities damaging the diaphragm, and improves the practicality and protection effect of the device.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
