Casting pipe automatic anchor interface

Abstract

The present invention relates to a mouthpiece structure which is used for connecting K-type cast pipes into pipeline. A sealing ring is placed in the inward-recessed groove of socket of the cast pipe, the spigot of another cast pipe is inserted into the socket of described cast pipe, said sealing ring can be tightly extruded between the socket and spigot of the cast pipes, a pressure flange is cover-mounted on the external periphery of the spigot, and the locking tap holes are radially and uniformly distributed on the pressure flange, and the T-type bolt holes are axially distributed and space from the locking tap holes, and the end face of the socket correspondent to T-type bolt holes is equipped with balt holes. The described locking tap hole nearby spigot external periphery is made into recessed groove in which pressure block is movably mounted.

Description

(1) Technical field [0001] The invention belongs to an interface structure in which a K-shaped cast pipe is connected to form a pipeline. (2) Background technology [0002] At present, when a K-type cast pipe is used to connect into a pipe, a sealing ring is placed in the inner groove of the socket of the casting pipe, and the socket of the other casting pipe is inserted into the socket of the casting pipe, and the sealing ring is tightly squeezed Between the socket and the socket of the cast pipe, sealing and anti-slipping can be achieved. However, casting pipes can only be constructed one by one when connecting and assembling, which is inefficient, and the width of the pipe-laying trench that needs to be dug is large, time-consuming and labor-intensive, and the construction period is long. Due to the construction in the pipe laying trench, the work is inconvenient and the environment is poor. The paved pipe has poor pressure bearing capacity and poor radial deformation resistan...

AI Technical Summary

Problems solved by technology

However, cast pipes can only be constructed one by one during connection and assembly, which is inefficient, and the width of the pipe laying ditch that needs to be dug is large, time-consuming and laborious, and the construction period is long

Due to the construction in the pipe laying ditch, the work is inconvenient and the environment is poor

The paved pipeline has poor pressure bearing capacity and poor resistance to radial deformation

When the temperature of the transported material increases or decreases and the length of the cast pipe changes, it is easy to leak due to the slippage of the socket of the cast pipe

In the construction of pipelines crossing rivers, lakes or over mountains, slippage and leakage occurred many times and rework occurred, which greatly increased the cost and extended the construction period.
