摘要:
氮气式水击泄压阀的压力精度设定问题与油气管道系统能否安全运行紧密相关,为进一步提高泄压阀的设定压力精度,构建了油气水三相流耦合水击模型和阀芯运动力学模型;根据泄压阀的工作原理,对泄压阀阀芯的受力情况进行分析,建立水击压强、氮气压力、弹簧力之间的数学联系;实现了油气水三相流耦合水击模型和运动力学模型的融合。研究结果表明:构建的数学模型能准确地计算出符合实际工况的水击压强、氮气压力、弹簧力的理论数值;水击压强、氮气压力与弹簧力大小呈周期性变化;氮气压力与弹簧力设定数值的确定,可进一步提高泄压阀的设定压力精度。
Abstract:
The problem of setting the pressure accuracy of the nitrogen type hydraulic pressure relief valve is closely related to the safe operation of the oil and gas pipeline system, so as to further improve the set pressure accuracy of the pressure relief valve. Firstly, a coupled water hammer model and a valve core movement mechanics model of oilgaswater threephase flow were constructed. Secondly, based on the working principle of pressure relief valve, the stress conditions of the pressure relief valve spool were analyzed, and the mathematical relationship between the water hammer pressure, nitrogen pressure and the spring force were established. Finally, the integration of the coupled water hammer model of the oilgaswater threephase flow and the kinetic mechanics model is realized. The results show that the mathematical model constructed can accurately calculate the theoretical values of water hammer pressure, nitrogen pressure, and spring force that are in line with actual working conditions; the water hammer pressure, nitrogen pressure, and spring force are periodically changed; the determination of the set value of nitrogen pressure and spring force, solves the problem of pressure accuracy setting of pressure relief valve.
