【摘要】：智能自力式減壓閥(簡(jiǎn)稱智能減壓閥)的膜片尺寸對(duì)控制部分的密封性能會(huì)產(chǎn)生重要影響,進(jìn)而影響閥門的壓力波動(dòng)范圍、壽命、功耗等性能參數(shù).本文提出了一種智能減壓閥膜片尺寸優(yōu)化設(shè)計(jì)方法,即依據(jù)力平衡方程建立智能減壓閥壓力相關(guān)性的理論模型,通過流動(dòng)實(shí)驗(yàn)和實(shí)時(shí)采樣獲取原始數(shù)據(jù),以此為基礎(chǔ)進(jìn)行回歸分析建立實(shí)際數(shù)學(xué)模型,采用有約束條件的最小值優(yōu)化模型對(duì)膜片尺寸進(jìn)行優(yōu)化.優(yōu)化結(jié)果表明:采用優(yōu)化后的膜片尺寸,壓差和減少了30%,最大壓差極值減少了7.7%,最小壓差極值減少了39.6%.這對(duì)有效降低控制系統(tǒng)漏率起到了有益的作用.
[Abstract]:The size of the diaphragm of the intelligent self-operated pressure reducing valve will have an important impact on the sealing performance of the control part, and then affect the pressure fluctuation range, life, power consumption and other performance parameters of the valve. In this paper, an optimal design method of diaphragm size for intelligent pressure reducing valve is proposed, that is, the theoretical model of pressure dependence of intelligent pressure reducing valve is established according to force balance equation, and the original data are obtained by flow experiment and real time sampling. On the basis of regression analysis, the actual mathematical model is established, and the membrane size is optimized by the minimum optimization model with constraints. The optimization results show that the optimum diaphragm size, pressure difference and pressure difference are reduced by 30%, the maximum pressure difference extreme value is reduced by 7.7%, and the minimum pressure difference extremum value is reduced by 39.6%. This can effectively reduce the leakage rate of the control system.
