DESIGN AND FUNCTION
The vacuum breaker was designed, manufactured and tested forallowing atmospheric air through the valve to rapidly displace draining liquid in the pipeline and prevent internal negative pressure damaging the arrangements potentially. To prevent damage, vapor must be allowed into or out of thepipeline & at specified vacuum condition. The volume rate of venting depends upon the pipe size, the pumping rates and the temperature. Refer to API Standard 2000 for the procedures to determine venting requirements. As a vacuum is drawn in the Piping line, for example, when fluid is being pumped out, the pressure pallet is held shut by atmospheric pressure. When the vacuum setting is reached, the pallet lifts and air is drawn in from the atmosphere.
