ABSTRACT:
A combined air release and vacuum breaker valve for pipelines has a ball float that acts directly upon both the vacuum breaker and air release valves which are concentric with one another and axially aligned with the ball float. To avoid adverse effects of high velocity flow of water into the float chamber, which tends to initially counteract buoyancy of the ball, a flow disturbing screen is connected to the lower end of the ball. The direct acting ball is connected to the pressure release valve member by means of a resilient lost motion connection, so that slight bouncing of the ball caused by turbulent flow in adjacent areas of the pipeline will not cause the air release valve member to bounce on and off its seat.
