【技术实现步骤摘要】
专利说明 一、
本技术涉及一种智能调压装置，尤其是比例电磁阀性能测试的智能调压装置。二
技术介绍
现有的比例电磁阀性能测试系统测试气源输入气压的调整，采用针形调压阀和U型压力计，靠手工逐点反复调节，不仅测试速度慢、准确度差，而且很不稳定，更无法对其压力特性曲线、流量特性曲线及其特征参数进行在线检测和综合参数的动态调整等不足之处。三
技术实现思路
本技术的目的是提供一种结构简单，由电脑控制的高速步进电机驱动机械装置，能无级快速调节，并保持每一调测点的气压稳定，以实现对比例电磁阀特性曲线、特征参数的智能化检测和动态调试的智能调压装置。本技术的目的所采用的技术方案是，包括有高速步进电机用法兰盘装配在壳架的隔板上，高速步进电机的主轴上的主动齿轮与从动齿轮啮合，其从动齿轮中心孔内连接有T形内螺纹套筒，T形内螺纹套筒的内螺纹与丝杆的中下部外螺纹啮合、外圆柱装配平面轴承，丝杆的下端装有行程开关档板、中上部开有导向槽内装有导向销钉，丝杆上部外圆连接有呈凹形圆环柱的锁紧环，锁紧环的环壁内螺纹与呈内台梯形的圆环柱的调压阀口下端外螺纹啮合，调压阀口的上顶端面与呈内台梯形的圆环柱的调压阀下端盖的下底端面之间，压有中间有孔的圆边呈半波环形的皮膜，调压阀下端盖中心装配有阀芯的下端穿过皮膜的中间孔和金属膜的中间孔，与调压弹簧一端相接，调压弹簧另一端穿过调压阀口中心孔与丝杆的顶端相接，调压阀下端盖上连接阀体，阀体的输出管装有气压检测嘴。本技术是借助于电脑指令使高速步进电机及其主轴上的主动齿轮和从动齿轮转动，从动齿轮及与之联为一体的T形内螺纹套筒的正、反回转运动转换成丝杆的上、下直线运动，通...
