Anti-drawing flexible pipe connector

Abstract

The invention discloses an anti-drawing flexible pipe connector. The connector comprises an insertion head and a socket head which are matched; the insertion head comprises a boss platform, a supporting boss and an insertion head connecting pipe connecting end connected with a pipe, and the boss platform, the supporting boss and the insertion head connecting pipe connecting end are sequentially connected from a port inwards; the socket head comprises an inner port, a conical slope with the inner diameter gradually decreased, a sealing inner hole and a socket head connecting pipe connecting end connected with the pipe, and the inner port, the conical slope, the sealing inner hole and the socket head connecting pipe connecting end are sequentially connected from a port inwards; and the anti-drawing flexible pipe connector further comprises a clamping ring which is arranged between the inner port and the supporting boss to enable the insertion head and the socket head to generate a swing angle. By means of the anti-drawing flexible pipe connector, pull separation of the insertion head and the socket head can be effectively prevented, water leakage accidents caused by axial displacement of the flexible connector pipe are avoided, strengthening pile beating needed during corner, plug or open installation of the flexible connector pipe is avoided, and the using safety and reliability of the flexible connector pipe are effectively improved.

Description

technical field [0001] The invention relates to a pipe joint, in particular to a pipe joint for large and medium-sized conveying media. Background technique [0002] The pipes that convey the medium must be reliably connected to ensure normal operation. Flexible interface connections are currently the most commonly used connection methods for pipes. [0003] At present, although the known flexible interface pipes can adapt to the uneven settlement of the foundation, they have no anti-drawing device, and the anti-drawing force depends entirely on the friction between the pipe and the soil. This is not only not suitable for open-air installation, but also when the backfill is too shallow or the pipe is subjected to excessive internal pressure, or at the plug and turning of the pipe, a reinforcement pier must be added to withstand the thrust of the pipe to prevent the joint from being pulled off. The interface being pulled off and displaced is the main cause of water leakage a...
