摘　　要：针对高温、高压电动阀门过长的传动链和大体积的问题,提出了一种新型高温、高压直驱电动阀门屏蔽式永磁电机(DDEAV-CPMSM)一体式结构。首先,探究了温度、压强、屏蔽套参数对电动阀门一体式结构应力应变分布的影响;然后,对比了不同屏蔽套参数下的电动阀门电磁性能,并对高温、高压下的危险截面进行了应力评定;在屏蔽套最优参数基础上,提出了加强环结构,比较了不同加强环尺寸下的等效应力,建立了危险截面下最大等效应力随加强环厚度、宽度、位置变化的函数曲线;最后,搭建了电动阀门一体式结构高温、高压实验平台,进行了加强环变形量测定。研究结果表明:加强环能提高电动阀门屏蔽套的安全系数,测量得到加强环外径平均值为126.172 mm,仿真模拟加强环外径值为126.06024 mm,相对误差为0.088%;该结果可为高温、高压下一体式电动阀门承压结构设计提供理论依据。Aiming at the problems of too long transmission chain and large volume of high temperature and high pressure electricactuated valve,a novel integrated structure of high temperature and high-pressure direct drive electricactuated valve canned permanent magnet synchronous motor(DDEAV-CPMSM)was proposed.Firstly,the influence of temperature,pressure and canned sleeve parameters on the stress-strain distribution of the integrated structure were explored.Then,the electromagnetic performance under different canned sleeve parameters was compared,and the stress evaluation of the dangerous section under high temperature and high pressure was carried out.On the basis of the optimal parameters,the reinforcing ring structure was proposed,the maximum equivalent stress under different reinforcing ring sizes was compared,and the function curve of the maximum equivalent stress in the dangerous section with the thickness,width and position of the reinforcing ring was established.Finally,a high temperature and high pressure experimental platform was built to analyze the influence on the strain of the reinforcing ring.The research results show that the reinforcing ring can improve the safety factor of the canned sleeve.The average value of the measured outer diameter of the reinforcing ring is 126.172 mm,the simulated outer diameter of the reinforcing ring is 126.06024 mm,and the relative error is 0.088%,which provides a theoretical basis for the design of the pressure-bearing structure of the integrated electric-actuated valve under high temperature and high pressure.
