【 摘 要 】

Safety relief device is one kind of safety accessories, which can ensure the safety of transportable pressure special equipment. As a common safety relief device for long tube trailer cylinder, rupture disc cascaded with fusible plug device was fund failure to release in time in the case of fire and abnormal action under conditions, so its safety and applicability are questionable. Double rupture disc safety device is a new kind of safety device used on the long tube trailer cylinders, compared to the traditional rupture disc cascaded with fusible plug device, which has better anti-fatigue and safety performance. However, the lack of corresponding design and test method limits the application of the double rupture disc safety device used on the long tube trailer. This paper gives a new practical design of double rupture disc safety device including structure design, verification of discharge area, and the leak detection system, to provide guidance for the engineering design and development of the double rupture disc safety relief device. Experiment verification is conducted, and the results indicate that the double rupture disc safety relief device meets the requirements of operating performance.
