快速阀是六十年代出现的一种新型液压控制元件,最初应用于快速操作的液压系统,如快速锻造水压机等.近年来,由于其数字化特征、可靠性及其它优点,在计算机控制的液压系统中越来越受到人们的重视.响应时间是这种阀的一个重要参数.它关系到控制系统的稳定性、精度、频宽等一系列性能.目前国内外所研制的快速阀,响应时间已达3ms.但其多为小通径的球阀或锥阀,控制流量较小(<131/min),常常只能当先导阀使用.作者分析了换向阀的工作过程,讨论了提高阀快速性的各种途径.从阀的结构、电磁铁、驱动电路三方面采取措施,设计制造了一种新型快速开关阀.带导流盘的阀芯,减少了
A new type of hydraulic control element that emerged in the 1960s, the fast valve was first used in rapidly operating hydraulic systems such as rapid forging hydraulic presses, etc. In recent years, due to its digital nature, reliability and other advantages, More and more people’s attention.Response time is an important parameter of this valve.It relates to the control system stability, accuracy, bandwidth and a series of performance.At present, the rapid valve developed at home and abroad, the response time has reached But it is mostly small diameter ball valve or cone valve, the control flow is small (<131 / min), often can only be used as a pilot valve.The author analyzes the working process of the reversing valve, discusses the valve to improve the rapidity A variety of ways from the valve structure, electromagnet, drive circuit to take three measures to design and manufacture of a new type of fast switching valve with a diversion disc spool, reducing the
