[0002] Hydrogen production by electrolysis of water involves converting electrical energy into hydrogen and oxygen through the process of electrolyzing water. The hydrogen is collected and used for various applications. In hydrogen production by electrolysis of water, the electrolysis process is usually carried out in an electrolytic cell, which consists of a cell body, an anode, and a cathode.

[0003] In the process of producing hydrogen through water electrolysis, the diaphragm will wear out after long-term use and needs to be replaced. When installing the diaphragm, the diaphragm and diaphragm gasket are usually integrally formed by welding or other means. The gap between the diaphragm and the gasket is small, making it difficult to replace the diaphragm. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a diaphragm gasket with a diaphragm that allows for easy disassembly of the diaphragm and the gasket, facilitating the replacement of the diaphragm.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A diaphragm gasket with edge binding includes a first gasket body and a diaphragm. A gasket placement groove is provided at the lower end of the first gasket body. The diaphragm is disposed on the inner top wall of the gasket placement groove. A second gasket body is disposed below the diaphragm. A movable member is disposed between the second gasket body and the first gasket body.

[0007] The movable component includes a movable groove formed at the lower end of the first gasket body, and a sliding groove formed on the inner top wall of the movable groove. A limiting ring is slidably connected between the circumferential inner walls of the sliding groove, and a movable ring is fixedly connected to the lower end of the limiting ring. The movable ring is fixed to the upper end of the second gasket body.

[0008] A limiting member is provided between the first gasket body and the second gasket body to limit the position of the diaphragm.

[0009] In a preferred embodiment, the present invention can be further configured such that: the limiting member includes a plurality of fastening threaded grooves formed at the lower end of the first gasket body, and a plurality of fastening bolts are provided below the second gasket body, and the fastening bolts movably pass through the upper end of the second gasket body and are threadedly connected to the fastening threaded grooves.

[0010] In a preferred embodiment, the present invention can be further configured such that: the upper ends of the first gasket body and the second gasket body are each provided with a plurality of mounting screw holes, and mounting bolts are threaded into the mounting screw holes.

[0011] In a preferred embodiment, the present invention can be further configured such that: a fitting ring is fixedly connected to the circumferential inner wall of the gasket placement groove, and the diaphragm is in contact with the circumferential inner wall of the fitting ring.

[0012] In a preferred embodiment, the present invention can be further configured such that: a compression protrusion ring is fixedly connected to the upper end of the second gasket body, and the outer diameter of the compression protrusion ring is consistent with that of the fitting ring.

[0013] In a preferred embodiment, the present invention can be further configured such that: the upper end of the first gasket body and the lower end of the second gasket body are each provided with a plurality of sealing grooves, and the upper end of the first gasket body and the lower end of the second gasket body are each provided with a heat-resistant coating.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. The device comprises a first gasket body, a second gasket body, a diaphragm, a sliding groove, a limiting ring, and a moving ring. When installing the diaphragm onto the first and second gasket bodies, the distance between the second and first gasket bodies is adjusted to the maximum. The first and second gasket bodies are then squeezed together to create a slight deformation. The diaphragm is then placed into the gasket placement groove of the first gasket body. Adjusting the position of the second gasket body can clamp and limit the diaphragm, facilitating diaphragm replacement and making it convenient to use.

[0016] 2. The device is equipped with a first gasket body, mounting screw holes, a second gasket body, and mounting bolts. After the diaphragm is installed between the first gasket body and the second gasket body, the second gasket body and the first gasket body are squeezed together to clamp the diaphragm.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-4 The present invention discloses a diaphragm gasket with edge binding, comprising a first gasket body 1 and a diaphragm 2. A gasket placement groove 14 is provided at the lower end of the first gasket body 1. The diaphragm 2 is disposed on the inner top wall of the gasket placement groove 14. A second gasket body 4 is disposed below the diaphragm 2. A movable component is disposed between the second gasket body 4 and the first gasket body 1.

[0025] The movable component includes a movable groove 9 formed at the lower end of the first gasket body 1, and a sliding groove 7 is formed on the inner top wall of the movable groove 9. A limiting ring 8 is slidably connected between the circumferential inner walls of the sliding groove 7, and a movable ring 10 is fixedly connected to the lower end of the limiting ring 8. The movable ring 10 is fixed to the upper end of the second gasket body 4.

[0026] A limiting member is provided between the first gasket body 1 and the second gasket body 4 to limit the diaphragm 2.

[0027] In this embodiment, reference Figure 4 The second gasket body 4 is connected to the limiting ring 8 through the moving ring 10. The groove diameter of the moving groove 9 is smaller than that of the limiting ring 8, so the limiting ring 8 slides up and down between the circumferential inner walls of the sliding groove 7 and will not leave the sliding groove 7. The second gasket body 4 and the first gasket body 1 are close to each other, so that the diaphragm 2 can be clamped and fixed between the second gasket body 4 and the first gasket body 1.

[0028] refer to Figure 3 The specific installation method of the diaphragm 2 with the first gasket body 1 and the second gasket body 4 is as follows: the distance between the second gasket body 4 and the first gasket body 1 is adjusted to the maximum, the first gasket body 1 and the second gasket body 4 are squeezed to form a slight deformation, the diaphragm 2 is placed in the gasket placement groove 14 of the first gasket body 1, and the position of the second gasket body 4 can be adjusted by the limiting component to clamp and limit the diaphragm 2, which can facilitate the replacement of the diaphragm 2 and make it convenient to use;

[0029] Preferably, although not shown in the figure, through holes can be opened on the first gasket body 1 and the second gasket body 4 for the conduction of electrolyte. The specific opening method can be selected by those skilled in the art.

[0030] Regarding the placement of diaphragm 2, here we take... Figure 4 Described from a specific perspective, the diaphragm 2 is placed on the inner top wall of the gasket placement groove 14, and during installation... Figure 1 From the perspective, the diaphragm 2 is placed on the inner bottom wall of the gasket placement groove 14.

[0031] For further details, please refer to Figure 3 and Figure 4 The limiting component includes several fastening threaded grooves 6 opened at the lower end of the first gasket body 1, and several fastening bolts 5 are provided below the second gasket body 4. The fastening bolts 5 move through the upper end of the second gasket body 4 and are threadedly connected to the fastening threaded grooves 6.

[0032] In this embodiment, reference Figure 4 The fastening bolt 5 is threadedly connected to the fastening threaded groove 6, and the fastening bolt 5 can move within the fastening threaded groove 6;

[0033] The specific limiting method is as follows: after the diaphragm 2 is installed between the first gasket body 1 and the second gasket body 4, the second gasket body 4 and the first gasket body 1 are squeezed so that the second gasket body 4 and the first gasket body 1 clamp the diaphragm 2. The fastening bolt 5 is rotated. As the fastening bolt 5 is gradually threaded into the fastening thread groove 6, the lower end of the fastening bolt 5 pushes the second gasket body 4 and the first gasket body 1 closer together, thereby achieving the purpose of clamping.

[0034] For further details, please refer to Figure 1 The upper ends of the first gasket body 1 and the second gasket body 4 are provided with several mounting screw holes 13, and mounting bolts 16 are connected to the internal threads of the mounting screw holes 13.
