Problems solved by technology

[0005] But there is a big problem with the above-mentioned socket interface: it is very difficult to disassemble after installation, and it is necessary to use special tools to pry up two or three parts of the stopper 104, so that The protruding ring 103 at this part is removed, and then pry other parts until the protruding ring 103 is completely removed
After the above situation occurs, the socket will protrude under the internal pressure of 2.5MPa, causing the tube to burst, and it cannot be used in mountainous areas with undulating terrain and high internal pressure.
[0011] Moreover, there is a welding process on the retaining ring 24' of the socket interface, which has poor corrosion resistance and cannot meet the corrosion resistance requirements of the underground application; at the same time, the ring adjustment mechanism 26 'It can only be clamped tightly, not loosened, and it is inconvenient to disassemble

Embodiment 1

[0051] A high-pressure internal self-anchor socket interface, including a pipe socket 1 and a pipe socket 2, the pipe socket 2 with a smaller inner diameter at one end of the pipe, the pipe socket 1 with a larger inner diameter at the other end, and the pipe socket 2 of a pipe Insert the pipe socket 1 of another pipe to realize the pipe connection.

[0052] Such as Figure 6-10 As shown, the end of the pipe socket 1 has an annular wall extending radially inward, and a self-anchor cavity 5 is opened on the annular wall, and a retaining ring 3 is arranged in the self-anchor cavity 5 . An annular protrusion 4 is arranged on the outer wall of the pipe socket 2 . When the pipe socket 2 is inserted into the pipe socket 1, the annular protrusion 4 is blocked by the retaining ring 3 to fix the pipe socket 2 and prevent the pipe socket 2 from coming out. There is also a rubber ring installation groove on the pipe socket wall located inside the self-anchor chamber 5 (the direction fro...

Embodiment 2

[0056] The difference between this embodiment and embodiment 1 is: as Figure 13 As shown, at least one of the two surfaces of the inner side of the self-anchor cavity 5 of the annular wall of the pipe socket 1 that cooperates with the retaining ring 3 is a spherical surface protruding outward, so that the contact between the retaining ring 3 and the self-anchor cavity 5 of the annular wall For spherical fit.

[0057] After the installation of the socket interface is completed, the retaining ring 3 is fastened on the outer wall of the pipe socket 2, close to the annular protrusion 4, and moves the pipe socket outward to eliminate the installation gap between the annular protrusion 4, the retaining ring 3 and the self-anchor cavity 5 . At this time, the fit between the retaining ring 3 and the annular wall is a spherical fit, so that the socket interface can be deflected at a certain angle in any direction, and the flexible connection of the pipeline is realized. And when def...

Embodiment 3

[0064] The difference between this embodiment and embodiment 1 is: as Figure 14 As shown, the fastening ends 3-2 of two adjacent retaining ring segments are fixed by studs, and the fastening ends 3-2 are provided with through holes that cooperate with the studs; the two sides of each fastening end 3-2 A nut is respectively arranged on the studs, the nuts between the adjacent fastening ends 3-2 are expansion nuts, and the nuts outside the adjacent fastening ends 3-2 are fastening nuts. The expansion of the retaining ring 3 can be realized by adjusting the expansion nut, without using other tools, which saves labor in practical application.

[0065] Installation method of the present invention comprises the steps:

[0066] A1. Install the retaining ring 3 in the self-anchor cavity 5 of the pipe socket, and the fastening end 3-2 protrudes from the disassembly hole 6 to install the bolt, and adjust the expansion nut between the adjacent fastening ends to make the fastening end ...

Abstract

The invention discloses a high-pressure internal self-anchoring bell socket The bell socket comprises a pipeline bell end of which the end extends inwards in the radial direction to form an annular wall, a pipeline socket end of which the outer wall inserted into the pipeline bell end is provided with an annular protrusion, and a check ring which is arranged in a self-anchoring cavity formed in the annular wall and used for fixedly connecting the pipeline bell end and the pipeline socket end, the check ring is of a split structure, the check ring comprises a plurality of check ring sections of which the two ends are provided with fastening ends, the fastening ends of the check ring sections protrude outwards in the radial direction, the fastening ends are detachably fastened in a mutually corresponding and matched mode, and dismounting holes corresponding to the fastening ends in position and allowing the fastening ends to extend out of the outer wall of the pipeline bell end are formed in the wall of the pipeline bell end. The self-anchoring bell socket has a certain-angle deflection capability, and can be used in mountainous areas with fluctuating terrains and high internal pressure.

Description

technical field [0001] The invention relates to a high-pressure internal self-anchor socket interface, which belongs to the technical field of pipeline interfaces. Background technique [0002] With the change of the environment and the requirements of social development, the country's investment in water conservancy projects has increased year by year, and it has been developed to many remote areas. Due to the complex geographical environment in these areas, the requirements for pipelines are getting higher and higher, not only for the pressure resistance, geological subsidence resistance and flexible connection of the pipelines, but also for the pipeline interface to meet the above requirements. [0003] Therefore, a socket interface with an anchoring structure (the anchoring structure is a block or similar parts) has appeared, which includes a socket and a socket (the inner diameter of one end of the pipe is a socket, and the inner diameter of the other end is a socket). ...
