LIVE LOAD PIPE BALL JOINT

摘要

A live loaded ball pipe joint design accommodates for seal decay without the need for maintenance or adjustment. The pipe ball joint includes a casing having a socket section with a substantially spherical interior surface. A ball pipe section is received in the socket section. A seal is received in an annular groove within the socket section and is disposed against the ball segment. A push ring is disposed against the seal and a spring is disposed against the push ring. A retainer is secured to the casing and is disposed against the spring for loading the spring against the push ring. The loaded spring accommodates for decay of the sealing components and automatically adjusts the position of the push ring as the sealing components decay.
