摘要

SYSTEM FOR LIMITING RATE OF PRESSURE RISE IN PIPELINEDURING HYDRAULIC IMPACTABSTRACT OF THE DISCLOSUREA system for limiting the rate of pressure rise in apipeline during a hydraulic impact comprising a jet valveinstalled in the pipeline, the additional outlet of said valvebeing connected with a non-pressure dump tank via an actuator,a pressuretight pneumatic compensator connected with the jetvalve and, via a pressure transmitter, with the rate ofpressure rise signal indicator whose outlet is connected withthe membrane drive of the actuator.The use of the system according to the invention willimprove the reliability of protection of the pipeline againstrupture during a hydraulic impact with minimum pressure lossesunder the steady operating conditions of the pipeline.
