在毛主席革命路线指引下,我国的液压技术,自无产阶级文化大革命以来,得到了很快的发展。液压阀已被广泛地用于控制机床和其它工作机械实现各种运动。液压阀的结构和液压装置的配置型式不断地发展变化,由过去管式连接的单体元件发展成为板式单体元件。阀与阀的连接也由管连接发展为块(板)连接,即用连接块、铸孔板、钻孔板、工字板等来代替过去常用的油管及管接头。进而又发展到叠加阀。 我所坚持三结合开门办科研,研制成功的叠加式液压阀,是我国的一种新型液压元件,在国外也是最近几年才出现的。它是集成化液压元件的一个品种。其特点是:每个阀有五个共用的进出油通道,结构紧凑,体积小,组装维修简便。元件之间的连接既不使用油管,也
Guided by Chairman Mao’s revolutionary line, our hydraulic technology has enjoyed rapid development since the Great Proletarian Cultural Revolution. Hydraulic valves have been widely used to control machine tools and other work machines to achieve a variety of sports. The structure of the hydraulic valve and the configuration of the hydraulic device constantly evolve and evolve from the single tube-connected unit to the single-tube unit. Valve and valve connections also developed from the pipe connection to the block (plate) connection, that is, with the connection block, perforated plate, drilling plate, Ipod instead of the past commonly used tubing and fittings. And then developed to superimposed valve. I adhere to the three combination of open door to do scientific research, the successful development of superimposed hydraulic valve is a new type of hydraulic components in China, it is only in recent years in foreign countries. It is a variety of integrated hydraulic components. Its features are: Each valve has five common access to oil, compact structure, small size, easy assembly and maintenance. The connection between the components neither uses tubing nor
