Abstract

Disclosed is a quick ball joint which comprises a ball shell connected with a pipeline and a ball body connected with another pipeline. The ball body is spherical, the inner wall of the ball shell is also a spherical shape for being engaged with the ball body, the inner wall is provided with a sealing ring positioned on the inner side of a vertex of the ball body; the front end of the ball shell is connected with a pressure cover, the inner surface of the pressure cover is an arc-shaped surface, radian of the arc-shaped surface is same with that of the surface of the ball body. As the sealing ring is not positioned at the highest point of a spherical center but at a position deviating 5-7mm from the spherical center, tightness of the ball joint is not very effective when in the absence of an external pull force; the highest point of the ball body extrudes the sealing ring when stretched by an external force, thereby pressing the sealing ring tightly and being capable of bearing relatively high pressure and simultaneously bearing large enough pull force. When in installation, people only need to insert a ball body end into the ball shell, rotate the pressure cover to lead a flange portion of the pressure cover to be screwed at a fastening position of the ball shell, and then plug a pin shaft to prevent the pressure cover from rotating, thereby finishing installation. Accordingly, the ball joint achieves simple and convenient installation.

Description

technical field [0001] The invention relates to a pipeline connection joint. Background technique [0002] The quick ball joint is a quick connection device used on the mud blowing pipeline of dredging engineering. It can rotate 15-17° in any direction with the center of the ball. It partially replaces flange connection, welding, etc., and can be used as an elbow use. It can play the role of deflection while connecting the pipe and the pipe, so as to solve the damage to the pipeline caused by the deflection of the floating pipeline caused by waves. Contents of the invention [0003] The object of the present invention is to provide a spherical pipe connection joint, which solves the problem of pipeline damage caused by pipeline deflection under external force, such as wind waves and seawater fluctuations. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] A quick ball joint, including a spherical shell connect...
