Features:

In pipeline water hammer negative, air valve opening, so that the tube Daowai air into the pipeline, lest in thepipe produced larger negative pressure, play a protective role; operation of pipeline system, when the pipelineinternal pressure or temperature changes and dissolved in the water of the air is released, air valves will be thetimely discharge, prevent pipeline in formation of gas and affect the operation of the pipeline system.

Application:

Water conveyance pipeline during the initial water filling, regular maintenance of pipeline after water filling the air inside the pipeline to discharge, avoid pressure fluctuations.
