【摘要】：液压截止阀作为液压传动与控制技术中的基本功能元件之一,在工业领域有着非常广泛的应用需求,其性能的好坏直接影响到所装备设备的工作精度、使用性能、加工质量和自动化水平,也间接影响到被加工产品的质量和可靠性。现有液压截止阀大多是采用手动驱动方式,妨碍了设备的自动化运行,且密封性能不够理想,故不能适用于性能要求较高场合的使用需求。本文在对传统液压截止阀的结构及密封方式深入研究的基础上,设计开发了一种操控性能良好、密封性能可靠,使用寿命较长的截止阀—卸荷式液控液压截止阀。文中以公称压力31.5MPa、流量10L/min规格为例,详尽描述了具体的设计过程,在此基础上完成了实物样机的加工制作、装配和调试。文中还针对该截止阀设计了一套液压测试系统,为完成对液控液压截止阀的使用规范制定及性能检测提供了条件。该液压测试系统包括液压试验台的结构设计、计算机测控平台硬件设计、基于LabVIEW数据采集系统软件设计,以及截止阀试验方法设计。最后举例介绍了液控液压截止阀的典型应用。本文研制的卸荷式液控液压截止阀,已经获得了国家发明专利,为相关液压控制系统的开发提供了硬件基础。
[Abstract]:As one of the basic functional components in the hydraulic transmission and control technology, the hydraulic globe valve has a very wide application demand in the industrial field. Its performance directly affects the working accuracy and performance of the equipment. Processing quality and automation level, also indirectly affect the quality and reliability of processed products. Most of the existing hydraulic globe valves are manually driven, which hinders the automatic operation of the equipment, and the sealing performance is not ideal, so it can not be applied to the use of high performance requirements. Based on the deep study of the structure and sealing mode of the traditional hydraulic globe valve, this paper designs and develops a kind of hydraulic valve with good control performance, reliable sealing performance and long service life. Taking the nominal pressure 31.5 MPA and the flow rate 10L/min specification as an example, the design process is described in detail. On this basis, the processing, assembly and debugging of the physical prototype are completed. A set of hydraulic test system is designed for the valve, which provides the conditions for the specification and performance testing of the hydraulic globe valve. The hydraulic testing system includes the structure design of the hydraulic test bed, the hardware design of the computer measurement and control platform, the software design of the data acquisition system based on LabVIEW, and the design of the test method of the cut-off valve. At last, the typical application of hydraulic stop valve is introduced. The unloading hydraulic control hydraulic stop valve developed in this paper has already obtained the national invention patent, which provides the hardware foundation for the development of the related hydraulic control system.
