摘要
针对现有的立柱与安全阀系统中的薄弱环节,即立柱下腔与安全阀之间的连接通道过窄,结合在大流量安全阀试验中蓄能器的快速释放,对蓄能器进行反向应用。在立柱内腔中集成蓄能器的功能,进而减少安全阀让压时的负荷,大幅度提高立柱的抗冲击性能。通过计算,在需要安装1 000 L/min的大流量安全阀的情况下,通过600 L/min的流通量即可实现相应的功能,可以提高相关立柱的抗冲击性能。
For avoiding the weak-link between the prop and the safety valve system, that the pipe between them is too narrow. For improving the impacting resistance ability, an accumulator that is used as a storage tank has been assembled in the prop. After calculating, it＇s easy to see that 600 L/min safety valve can be used in the condition that need 1000L/min safety valve. The impacting resistance ability has been increased obviously.
