ABSTRACT:
Apparatus and method for draining liquid from a vacuum line without interrupting the vacuum. The apparatus consists of a storage tank attached to a vacuum line by a drainage pipe having a one-way valve in the pipe permitting the flow of liquids away from the vacuum line and into the tank. A vacuum connection between the vacuum line and the tank through a three-way valve maintains the tank under vacuum while the three-way valve maintains the connection opened between the vacuum line and the tank. A high pressure line also connects to the tank through the three way valve. A sensor responsive to the level of fluid in the tank generates a signal to operate the three-way valve and simultaneously connect the high pressure line and disconnect the vacuum line from the tank. When the pressure condition in the tank is thus reversed, the tank is drained. The method described is that employed when using this apparatus to drain a vacuum line without interrupting the vacuum.
