一、简介先导型低功率电磁阀是国外八十年代推出的新产品。1981年,机械工业部作为38项国家重点攻关项目下达给我厂。我厂经过四年多时间的努力,根据国情,自行设计和试制了压力级为63kgf/cm~2和210kgf/cm~2先导型低功率电磁阀(图1).分别在83年和85年作了样机技术鉴定。各项技术指标都达到设计要求,主要技术性能接近日本丰兴公司样机水平。先导型低功率电磁换向阀是一种新型的节能产品。该系列阀采用先导阀双级控制结构,其动作原理与电液换向阀相同,所不同的是该系列阀的先导部分巧妙地安置在主阀的两端,使常规电磁换向阀变成了电液换向阀,而外形尺寸及安装连接尺寸不变。安装
I. Introduction Pilot-oriented low-power solenoid valve is a new product introduced in the 1980s. In 1981, the Ministry of Machinery Industry issued to our factory 38 key national key research projects. I plant after more than four years of hard work, according to the national conditions, to design and trial-produced their own pressure level of 63kgf / cm ~ 2 and 210kgf / cm ~ 2 pilot-type low-power solenoid valve (Figure 1) Made a prototype technology identification. The technical indicators have reached the design requirements, the main technical performance close to the level of Japan’s Fengxing prototype company. Pilot low-power electromagnetic valve is a new type of energy-saving products. The series of valves using pilot valve two-stage control structure, the operation principle and the electro-hydraulic valve the same, the difference is that the series of valve pilot part cleverly placed at both ends of the main valve, the conventional solenoid valve into The electro-hydraulic valve, and the overall dimensions and installation of the same size. installation
