Air Release Vacuum Breaker Valve

vacuum breaker


A vacuum breaker is an attachment commonly placed on a bibcock valve or toilet or urinal flush valve, that prevents water from being siphoned backward into the public drinking water system. This prevents contamination should the public drinking water system's pressure drop.


An anti-siphon device that prevents the backflow of contaminated water into the water supply system.


A mechanical device which automatically vents a water line to the atmosphere when subjected to a partial vacuum, thus preventing backflow. (See backflow, air gap, backflow preventer.)

air release


Test for determining the relative ease of removing air from a plastisol.


allowing air to escape during pressurization of a distribution system using an air/vacuum release valve.

valve


A device for controlling the passage of fluid through a pipe or duct, esp. an automatic device allowing movement in one direction only


A membranous fold in a hollow organ or tubular structure, such as a blood vessel or the digestive tract, that maintains the flow of the contents in one direction by closing in response to any pressure from reverse flow


device in a brass wind instrument for varying the length of the air column to alter the pitch of a tone


a structure in a hollow organ (like the heart) with a flap to insure one-way flow of fluid through it


control consisting of a mechanical device for controlling the flow of a fluid


A cylindrical mechanism in a brass instrument that, when depressed or turned, admits air into different sections of tubing and so extends the range of available notes
