AUTOMATIC PRESSURE RELIEF DEVICE FOR WATER PURIFIER

摘要

A pressure relief device used in a water purifier for ejecting abnormal water pressure is disclosed. The device includes a T-shaped tube composed of a connecting tube and a valve tube. The connecting tube has a main channel. The valve tube is formed with a connecting hole communicating with the main channel and an inner hole communicating with the connecting hole. The connecting hole is less than the inner hole in diameter to form a step therebetween. A plug is fastened to an outer end of the valve tube and has a trough therein. The trough communicates with the inner hole. A ball is placed in the inner hole on the step to normally bung the connecting hole. A compression spring is placed in the inner hole and clamped between the ball and the plug to elastically push the ball.
