Pipe sealing chuck with high sealing performance

Abstract

The invention discloses a pipe sealing chuck with high sealing performance, relates to the technical field of pipe strength detection, and aims to solve the technical problem that the sealing performance of the end part of the pipe is insufficient. The key points of the technical scheme are that fixing flanges are arranged on the outer side walls of an end sleeve cover, clamping half shells are arranged on the two sides of the end sleeve cover, and the inner side wall of each clamping half-shell is provided with a fixed half-ring groove for inserting the corresponding fixing flange; the two clamping half shells are detachably connected; and an abutting plate is arranged in the sealing cavity, a rubber pad is arranged on the end wall, deviating from the bottom wall direction of the sealingcavity, of the abutting plate, and a pressure spring is arranged between the bottom wall of the sealing cavity and the abutting plate. Due to the fact that the pressure spring applies pressure to theabutting plate, so that the abutting plate enables the rubber pad abut against the end part of the pipe, the rubber gap can be fully attached to the end wall of the pipe, and therefore the aim of effectively improving the sealing performance of the end part of the pipe is achieved.

Description

technical field [0001] The invention relates to the technical field of pipe strength detection, in particular to a pipe sealing chuck with high sealing performance. Background technique [0002] The pipe needs to bear a certain water pressure in the practical process, so the strength of the pipe will be tested regularly during the production process to ensure the qualification rate of the pipe; Inject water to test the pressure the tubing can withstand. [0003] Structural reference of existing pipe sealing chucks figure 1 , which includes an end cover 1, the inner side wall of the end cover 1 is a sealed cavity 12 for the insertion of the end of the pipe 8; the two sides of the end cover 1 are respectively provided with a clamping half shell 2, two A clamping half-shell 2 is used to fix the outer wall of the pipe material 8; the outer wall of the end cover 1 is provided with a fixed flange 11, and the inner wall of the clamping half-shell 2 is provided with a fixed half-r...

Problems solved by technology

[0004] However, there is a certain deflection in the end of the pipe material 8 when it is cut, so that the end portion of the pipe material 8 cannot fully fit with the inner wall of the sealed cavity 12; There is a certain gap between the inner walls of 12, resulting in water leakage, resulting in insufficient sealing of the end of the pipe 8, which affects the test results, so it needs to be improved
