- 摘要:
- 膜片破裂压力是膜片阀最关键的性能参数，由于影响因素较多，通常膜片破裂压力散差较大，不容易满足系统的使用要求。为提高膜片阀破裂压力稳定性，通过理论分析和应力计算，从原材料、加工、测量和试验系统等方面，对影响膜片破裂压力的各因素进行了梳理和分析，提出需进行着重控制的3个影响因素，包括材料抗拉强度、刻痕剩余厚度和试验系统，并通过了某姿控动力系统贮箱后膜片组件研制的验证。研究结果表明，通过对材料抗拉强度、刻痕剩余厚度和试验系统进行严格控制，能够有效提高膜片阀破裂压力稳定性，该方法可推广应用于同类产品的研制。
- Abstract:
- The membrane bursting pressure is the key performance parameter for a membrane valve, but there are many influencing factors to course great difference of membrane bursting pressure usually, which can't satisfy system's requirement easily. In order to improve the bursting pressure stability of the membrane valve, in this paper, all the influencing factors in the aspects of raw material, fabrication, measurement and testing system are collated and analysed by theoretical analyse and stress calculation. Based on this, three main factors which should be strictly controlled are listed. They are extension strength of material, rest thickness of nicks, and testing system. The control measures were used in membrane valve of a power system. The results show that the bursting pressure stability for membrane valve can be improved effectively by strict control to the three factors, and it can be used in research of other similar products.
