PIPELINE SURGE RELIEF VALVE |
摘要 |
A surge relief valve suitable for high pressure application, for example in a crude oil pumped pipeline. The valve has a plug (22) movable to expose different areas of an energy-absorbing cage trim (20) to fluid flow. The plug position is controlled by a control device (80) proportionately responsive to changes in upstream fluid pressure. The valve requires no external power for its actuation. <IMAGE> |
