摘要:

为了设计一种用于油井液位测量系统的气动高速大流量开关阀,利用小流量的先导高速开关阀驱动大通径的主阀芯.提出以控制腔的充放气过程中压力特性来描述该阀的动态特性.基于热力学、动力学、气压传动等理论详细建立数学模型,并搭建内外爆气动开关阀的实验平台来验证模型的正确性.对阻尼孔通径、控制腔体积等影响动态特性的因素进行分析和优化.结果表明,仿真与实验相符.增大控制腔体积可减小压力振幅幅度,但阀芯开启时间变长;而阻尼孔通径与先导阀通径的比值在0.13~0.27内系统的响应特性颇好.实验结果表明,该阀有效解决大流量与高切换速度之间的矛盾.

Abstract:

A high-speed on/off valve with large flow rate, employing a pilot high-speed on/off solenoid valve to actuate a large diameter main valve, was developed for measuring the liquid level in a well. A new method which used the pressure variation characteristic in the control chamber during the charging-discharging processes to de- cribe the dynamic characteristics of the valve was proposed. A detailed mathematical model based on the therm- odynamics, kinetics,pneumatic transmission and some other theories was established. A experimental system was built up to verify the simulation result. Some factors having influences on the dynamic characteristics of the valve, such as the orifice diameter and the control chamber volume, were analyzed and optimized. The agreeme-nt between the experimental data and the simulation results verified the effectiveness of the mathematical models and the experimental system. Results also shows that increasing the control chamber volume would reduce the vibration amplitude, but the opening time of the valve would be prolonged. When the diameter ratio of the orific- e and the pilot valve is within the range of 0.13 ~ 0.27, the valve performs good response characteristics. The  valve developed solves the contradiction of high speed and large flow rate.
