摘要
现代科技的飞速发展,使得所有的领域都走向机械化,无论是农业、工业还是军事等这些都离不开液压技术。没有液压系统的支持,全面的机械化就难以实现。小到医疗设备,大到航空母舰,这些都离不开液压系统。所以我们对液压元件(如:先导式减压阀)的掌握十分有必要。
本次设计是对先导式减压阀进行结构设计。首先对先导式减压阀结构的探究,本人拟定了两种方案来对先导式减压阀进行研究:一种是管接式的,另一种是板接式的。通过对比和分析,管接式的装配方便且结构简洁明了,没有复杂的结构,所以我选择了现在应用最普遍的管接式的结构来进行先导式减压阀的结构设计。通过对阀内部的尺寸参数和结构来进行设计,来提高阀的灵敏性和精确度。
关键词:先导式减压阀,管接式,尺寸参数
Abstract
The rapid development of modern science and technology, make all fields to mechanization, agricultural, industrial or military, etc. These are inseparable from the hydraulic technology. Without the support of hydraulic system, prehensive mechanization is difficult to achieve. Small to medical equipment, to the carrier, these are inseparable from the hydraulic system. So we for ponents (such as: pilot operated pressure reducing valve) control is very necessary.
The design is carried out on the pilot operated pressure reducing valve structure design. First of all, the explore of pilot operated pressure reducing valve structure, I drew up two plans to study of pilot operated pressure reducing valve: one is the pipe joint type, the other is a plate type. Through parison and analysis, pipe socket type of installation is convenient and simple structure, plex structures, so I chose the application now the mon joint type of structure to carry out pilot operated pressure reducing valve's structure design. Through to the inside of the valve size parameters and structure design, to improve the sensitivity and accuracy.
Key words:Pilot operated pressure reducing valve, pipe type, size parameters
第一章引言
液压传动有很多机械传动没有的优势,如调节方便、反应灵敏、结构简单、传动能量大等。
