[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 This utility model provides a technical solution: a high-strength diaphragm valve composite diaphragm, comprising a diaphragm valve diaphragm body 1, a mounting plate 2, a positioning mounting groove 3, an upper fixing collar 4, a fixing bolt 5, a fixing tooth 6, a lower fixing collar 7, a first pad 8, a second pad 9, a limiting buckle groove 10, and a limiting buckle block 11. The mounting plate 2 is fitted onto the outer wall of the diaphragm valve diaphragm body 1. The diaphragm valve diaphragm body 1 is installed in a limiting insertion with the mounting plate 2 through the positioning mounting groove 3, and the shape of the positioning mounting groove 3 matches the shape of the outer wall of the diaphragm valve diaphragm body 1. This makes it easy to position and install the diaphragm valve diaphragm body 1, ensuring stable installation and providing a protective function.

[0021] The diaphragm body 1 of the diaphragm valve is installed by interlocking with the positioning and mounting groove 3 through the limiting groove 10 and the limiting block 11. The limiting groove 10 and the limiting block 11 are made of magnetic material, which allows the diaphragm body 1 of the diaphragm valve to be quickly installed magnetically, with stable disassembly and assembly, and good performance.

[0022] The diaphragm body 1 of the diaphragm valve has a first pad 8 at the top and bottom, and a second pad 9 in the middle. The first pad 8 and the second pad 9 are distributed in a clamping position. The first pad 8 is made of polyurethane, and the second pad 9 is made of honeycomb soft polylactic acid. This makes the first pad 8 and the second pad 9 effectively resistant to tensile stress and corrosion, resulting in better performance.

[0023] An upper fixing ring 4 is fitted onto the outer side of the upper end of the diaphragm body 1 of the diaphragm valve, and a lower fixing ring 7 is fitted onto the outer side of the lower end of the diaphragm body 1. The upper fixing ring 4 and the lower fixing ring 7 are distributed in a clamping and wrapping position with the diaphragm body 1 of the diaphragm valve. The upper fixing ring 4 and the lower fixing ring 7 are made of metal, which makes it easy for the upper fixing ring 4 and the lower fixing ring 7 to fit and protect the diaphragm body 1 of the diaphragm valve, and the structure is more stable.

[0024] The upper fixing collar 4 and the lower fixing collar 7 are fixedly installed to the diaphragm body 1 of the diaphragm valve by fixing bolts 5 and fixing teeth 6, which makes the upper fixing collar 4 and the lower fixing collar 7 easy to disassemble and install, and easy to replace independently. The inner walls of the lower fixing collar 7 and the upper fixing collar 4 are fixedly connected with fixing teeth 6, and the inner and outer sides of the lower fixing collar 7 and the upper fixing collar 4 are connected by fixing bolts 5. The inner wall of the mounting plate 2 is provided with a positioning mounting groove 3, and the upper edge of the inner wall of the positioning mounting groove 3 is provided with a limit buckle groove 10. The upper edge of the upper fixing collar 4 is fixedly connected to the middle position of the limit buckle block 11, and the limit buckle block 11 is installed by insertion with the limit buckle groove 10.

[0025] Working principle: When using this high-strength diaphragm valve composite diaphragm, firstly, the diaphragm valve body 1 of the device is inserted into the positioning mounting groove 3 of the mounting plate 2, and then magnetically spliced ​​with the positioning mounting groove 3 by the limiting buckle groove 10 and the limiting buckle block 11. Then, the diaphragm valve body 1 can be stretched for use. The materials of the first pad 8 and the second pad 9 provide effective tensile strength and corrosion resistance. During use, it can be reinforced by the upper fixing collar 4 and the lower fixing collar 7. When damaged, it can be quickly disassembled and replaced by the fixing bolts 5 and fixing teeth 6. This is the usage process of this high-strength diaphragm valve composite diaphragm.
