SYSTEM FOR LIMITING RATE OF PRESSURE RISE IN PIPELINE DURING HYDRAULIC IMPACT

摘要

SYSTEM FOR LIMITING RATE OF PRESSURE RISE IN PIPELINE DURING HYDRAULIC IMPACT A system for limiting the rate of pressure rise in a pipeline during a hydraulic impact comprising a jet valve installed in the pipeline, the additional outlet of said valve being connected with a non-pressure dump tank via an actuator, a pressuretight pneumatic compensator connected with the jet valve and, via a pressure transmitter, with the rate of pressure rise signal indicator whose outlet is connected with the membrane drive of the actuator. The use of the system according to the invention will improve the reliability of protection of the pipeline against rupture during a hydraulic impact with minimum pressure losses under the steady operating conditions of the pipeline.
