Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline sealing, and in particular relates to a pipeline interface sealing structure for water conservancy projects. Background Art

[0002] The sealing structure of the pipe interface for water conservancy projects can include a variety of designs and materials, depending on the type of pipe, purpose, working environment and required sealing performance, including flange connection sealing structure. Flange connection is a detachable joint structure that tightly connects two pipes or pipe fittings through flanges and bolts.

[0003] The pipe interface sealing structure for water conservancy projects currently on the market has the following problems when applied:

[0004] 1. In the actual use process, the traditional sealing structure of the pipeline interface for water conservancy projects usually adopts a flange connection sealing structure, but the sealing performance of a single flange seal is not strong, so its sealing performance is weak during use;

[0005] 2. Most of the pipe interface sealing structures used in water conservancy projects are often integrated structures when used. Once the sealing structure is deformed, it can only be replaced as a whole during later maintenance. Therefore, it is inconvenient to replace the sealing structure during application.

[0030] A spring 9 is provided inside the frame 8, a pull rod 10 is embedded inside the spring 9, and a ball head 17 is provided on the top of the pull rod 10. Due to the provision of the spring 9, the asbestos board is pressed against the outside of the flange 2 under the action of the elastic force of the spring 9.

[0031] The side of the first shell 3 is connected to the mounting plate 5, and the side of the second shell 4 is provided with a mounting seat 6. The mounting plate 5 and the mounting seat 6 are provided to facilitate installation inside with fasteners.
