[0002] A wafer-on-wafer check valve is a type of valve commonly used to control flow in fluid systems, preventing reverse flow. It consists of two plate-like bodies, and the relative movement between the plates controls fluid flow. This type of check valve is suitable for medium- and high-pressure piping systems.

[0003] In the existing technology, when installing the valve disc in the valve body, first, the staff needs to manually match it without a guide component, and after the matching is completed, the components on the valve disc are fixed with bolts using tools. Since tools are required, the efficiency of the installation process is greatly reduced, which may cause a waste of time for projects that require rapid construction and maintenance.

[0025] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a sealed double-plate clamp check valve that is easy to install, comprising: a mounting mechanism 1, an auxiliary mechanism 2 is provided on the inner wall of the mounting mechanism 1, the mounting mechanism 1 comprises a valve body 11, an empty tube 14 is provided on the inner wall of the valve body 11, the inner wall of the valve body 11 is vertically connected to one end of the empty tube 14, a locking block 15 is provided on the inner wall of the empty tube 14, the inner wall of the empty tube 14 is movably connected to one end of the locking block 15, and the locking block 15 The top side of the valve body 11 is snap-fitted with the inner wall of the valve body 11, the inner wall of the valve body 11 is provided with a spring piece, the bottom end of the empty tube 14 is provided with a limiting rod 13, the bottom end of the empty tube 14 is snap-fitted with the inner wall of the limiting rod 13, the inner wall of the valve body 11 is provided with a spring piece 2 110, the inner wall of the valve body 11 is fixedly connected to the bottom end of the spring piece 2 110, the top of the spring piece 2 110 is provided with a fixing plate 19, the top of the spring piece 2 110 is fixedly connected to the bottom side of the fixing plate 19, and the fixing plate 19 is fixedly connected to the bottom side of the fixing plate 19. One end is fixedly connected to one side of the empty tube 14, and the inner side of the empty tube 14 is vertically slidably connected to the outer side of the extrusion block 112. The bottom end of the extrusion block 112 is provided with a movable arm 16, and the bottom end of the extrusion block 112 is fixedly connected to the middle end of the movable arm 16. One end of the movable arm 16 is movably connected to one side of the top of the locking block 15. The outer side of the limiting rod 13 is provided with a valve disc 12, and the outer side of the limiting rod 13 is movably connected to one side of the valve disc 12. A sealing ring 113 is provided on one side of the valve disc 12, and one side of the valve disc 12 is fixedly connected to one end of the sealing ring 113. One end of the sealing ring 113 is fitly connected to the inner wall of the valve, and a positioning ring 114 is provided on the inner side of the valve body 11. The inner side of the valve body 11 is slidably connected to one end of the positioning ring 114, and the inner side of the positioning ring 114 contacts one side of the limiting rod 13.

[0030] In this embodiment, by installing the sound insulation cotton 21 and corrosion-resistant cotton 22 designed in the valve body 11, the sound insulation cotton 21 can effectively absorb the noise generated during the flow of liquid or gas, reduce the noise of the pipeline system during operation, and create a quieter working environment, which is especially important in buildings, residential areas or industrial environments where noise is strictly controlled. The corrosion-resistant cotton 22 can provide additional protection to resist the erosion of the valve body 11 and its internal components by corrosive substances in the medium, thereby extending the service life of the valve and reducing maintenance costs.
