Problems solved by technology
[0002] At present, the joints of large-diameter alloy pipes generally adopt a single rubber sealing ring socket connection method. After the pipes are connected, they are affected by multiple factors such as water gravity and geological changes in the pipes, and the joints are prone to leakage and loosening. The closed water tightness test required by the standard seriously restricts the application of large-diameter double-wall bellows

Embodiment Construction
[0019] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0020] figure 1 , figure 2 and image 3 A rigid-flexible alloy pipe with a built-in elastic locking mechanism and its connection method are shown, including an alloy pipe main body 1, an annular electromagnet 2, a socket connector 3 located on the left side of the alloy pipe main body 1, and an alloy pipe main body 1 The socket joint 4 on the right side has an internal water guide ring 5 with an integral structure protruding inward on the inner surface of the socket joint 4. The inner diameter of the internal water guide ring 5 gradually becomes smaller from left to right, and the inner water guide ring 5 There is an annular assembly groove 6 on the surfac...

The invention relates to the technical field of connecting pipes, and in particular to a rigid-flexible alloy pipe with a built-in elastic locking mechanism and a connecting mode thereof. According tothe rigid-flexible alloy pipe with the built-in elastic locking mechanism and the connecting mode thereof, an inner water guide ring and an assembly limiting ring are arranged at the connecting endsof a socket connector and a spigot connector; an annular assembling groove with a built-in elastic adjusting lever mechanism is formed in the right side surface of the inner water guide ring; a triangular limiting block at the top end of a lever mechanism is adjusted to be inserted into a guide limiting blind hole to fix the connector; an annular fixing groove provided with a built-in annular electromagnet is formed in the outer side face of an alloy pipe body; the annular electromagnet matches an iron extrusion spring to conduct overturning control over the adjusting lever mechanism, so thatthe connecting ends are conveniently disassembled as needed; and the sealing performance and durability of the elastic adjusting lever mechanism are greatly improved through a rubber sealing sleeve ona sealing ring and an inner sealing ring with a resistance ring.
Description
technical field [0001] The invention relates to the technical field of connecting pipes, in particular to a rigid-flexible alloy pipe with a built-in elastic locking mechanism and its connection method. Background technique [0002] At present, the joints of large-diameter alloy pipes generally adopt a single rubber sealing ring socket connection method. After the pipes are connected, they are affected by multiple factors such as water gravity and geological changes in the pipes, and the joints are prone to leakage and loosening. The closed water tightness test required by the standard seriously restricts the application of large-diameter double-wall corrugated pipes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved rigid-flexible alloy pipe with a built-in elastic locking mechanism and its connection method in order to solve the problems existing in the above background technology. [0004] The techn...
