摘要阀门是流体管路的控制装置。它是用来切断和接通管路介质、调节介质的压力和流量，改变介质的流动方向以及保护管路系统或设备的安全运行。随着现代技术的发展，在工业、农业、国防、科研及人民生活等方面，流体管路的应用日益普遍，对阀门的需要量愈来愈大。其中阀门在船上的应用也是不可或缺的，而且数量和种类繁多。为了便于船用阀门的生产，成组技术也得到了广泛的应用。成组技术在船用阀门中的应用主要运用其原理进行成组工艺和成组夹具的设计。49475

本文通过应用成组技术对大量各类船用阀门零件的分类成组，编制成组工艺并对针对钻阀门法兰孔设计成组夹具，灵活运用成组技术。综合分析成组技术在船用阀门生产中发挥的巨大作用，具体介绍成组工艺的概念和设计过程以及成组夹具的设计。

 Abstract The valve is fluid pipeline control device. It is used to cut and connect a pipeline medium, medium pressure and flow regulation, change the direction of the flow medium and the protection of pipe system or equipment safe operation. With the development of modern technology, in industry, agriculture, national defense, scientific research and people's life, the fluid pipeline applications increasingly widespread, the valve need increasing. Wherein the valve’s Application in ship is essential, and the number and variety of. In order to facilitate the marine valve manufacturing, group technology has been widely applied. The group technology in the application of marine valve mainly uses the principle of group technology and the Group Fixture design.

In this paper, through the practical application of group technology for large marine valve types of parts classification group, a preparation of group technology and Design Group Fixture, ultimate flexibility in the use of group technology. Comprehensive analysis of group technology in marine valve production play a significant role in group technology, introduces the concept and the design process as well as the Group Fixture design.

Key words: marine valves, group technology, group technology, Group Fixture
