Abstract

The socket-type pipe interface with an anchoring structure of the present invention relates to a socket-type pipe interface with an anchoring structure for connecting ductile iron pipes. The purpose is to provide a socket-type pipeline interface that can improve anchoring reliability, extend structural life, reduce pipeline maintenance costs, facilitate optimization simulation of the interface structure, and increase pipeline transportation capacity. The invention includes a socket, a socket, and a seal between the socket and the socket for sealing and locking a pipeline interface; the socket includes a first annular vertical wall, a tapered wall, a cylindrical inner wall and a second annular vertical wall. The defined annular grooves are connected in turn; the sealing member includes an elastic material ring and a plurality of anchors embedded therein; the anchoring member includes a head and a plurality of meshing teeth; the anchoring member is provided with a center of rotation, and the head is connected to the annular groove The part where the grooves are in contact is an arc support surface; the contact area between the arc support surface and the annular groove is located at the intersection of the first annular vertical wall and the tapered wall.

Description

technical field

[0001] The invention relates to a socket-type pipe joint, in particular to a socket-type pipe joint with an anchoring structure for connecting ductile iron pipes. Background technique

[0002] Ductile iron pipes are used in the field of water and gas transmission. The two ends of the ductile iron pipes are sockets and sockets respectively. The main connection method of two ductile iron pipes in the pipeline is: the socket of one pipe and the socket of the other pipe Plug-in butt, and install a sealing rubber ring between the socket and the socket. Ductile iron pipes are supported by soil or other supports during use. In areas with poor geological conditions or prone to earthquakes, the supporting soil or other supports are prone to displacement, which can easily lead to plug-in socket and socket parts. If the axial relative movement or tilting movement opposite to the installation direction is severe, the structure may lose its sealing effect and cause water...
