介绍一起液氧内压缩流程中液氧泵回流阀爆裂事故的经过和破坏情况,初步认为事故的原因可能是阀门制造缺陷导致升压过程中上阀体破裂后高压液氧泄漏,进而引发化学性爆炸。最后提出了防止液氧泵回流阀燃爆的预防措施。
This paper introduces a process of liquid oxygen and oxygen compression in the process of liquid oxygen pump return valve bursts and the destruction of the initial situation that the cause of the accident may be caused by valve manufacturing defects led to the valve during rupture high pressure liquid oxygen leakage after the rupture, explosion. Finally, the preventive measures to prevent the explosion of liquid oxygen pump return valve are proposed.
