UNDERGROUND PIPE COUPLINGS FOR EMERGENCY REPAIR DURING PIPE BREAKAGE

摘要

The present invention relates to an underground pipe coupling for emergency repair during pipe breakage provided with a ball and socket coupler joint having ball joint (5) which is free to slide inside socket joint (3) fastened by means of ball joint backing ring (4) along with ˜O™ ring (7) positioned in between them. A pair of Grip cam mounting plate (1), mounted with grip cam (6) is provided. Out of which, one connects at one end of the broken pipe and ball joint (5) and the other one connects the other end of the broken pipe and socket joint (3) in a watertight manner by means of a resilient sealing ring (2) placed in between each one of them. Grip cam rotates on an eccentric axis in an anti-clockwise direction and locks the pipe to prevent decoupling of the pipe joint, but is free to rotate in its own axis as per the pipe moment in leaner direction.
