The passive control burst protection device for pressure pipeline

The safety of pressure pipeline conveying is a hotspot issue for us. As to the disadvantages of the existing protect device, this paper proposes four shuttle-type passive burst protect devices for pipeline conveying in turn based on the structure intelligence principle of adjustable difference shuttle-type valve. After the performance comparison of them in depth, a new applicable device for the safety of pressure pipeline is presented with the function that it is effective as long as the pressure media exists in the pipeline.
