梭式管道爆破保护装置是一种自力式全自动保护装置,当管道泄漏达到设定的保护值时,可迅速截断输送制止泄漏。为防止水击采用减缓关闭时间,拉长关闭行程和向外泄压等措施。推出一种无冲击梭式管道爆破保护装置,并对该装置的动态特性进行了试验研究,测量出水击压力瞬态冲击波形、峰值大小和波动持续时间等动态特性,并对试验结果进行了分析,确定出最佳方案,使管道运行更加安全可靠。 Shuttle pipe blasting protection device is a self-contained automatic protection device, when the pipeline leakage reaches the set value of protection, can quickly cut off the transmission to stop the leak. In order to prevent the use of water hammer to slow down the closure time, extend the closing stroke and outward pressure relief and other measures. A kind of impact-free shuttle blasting protection device is introduced. The dynamic characteristics of the device are tested and the dynamic characteristics of transient impact waveform, peak size and duration of surge are measured, and the test results are analyzed , Determine the best solution to make the pipeline more safe and reliable operation.
