Laboratory Tests of a Hydraulic Pressure Surge Reliever.

摘要

A 4-inch Flexflo (trademark) model 887 pressure surge reliever valve was tested in the laboratory to determine the valve's capability to reduce positive pressure surges in water pipelines. The valve was supplied by the Grove Valve and Regulator Company. The valve was placed on a pipeline upstream of a quick closing gate valve. During the tests, the gate valve was slammed shut to produce a sharp pressure wave traveling upstream. Performance of the surge reliever valve was determined by measuring the reduction in the pressure wave as it traveled past the valve.
