摘要本论文主要阐述了目前国内外船用阀门的研发状况，发展动态和发展方向，以及船用阀门在各个行业中的重要作用，研究了目前国内外阀门的现状，针对国内在研发阀门上耗时、耗材多等缺点，提出了参数化的制造思想56666
随着石油，化工工业的快速发展，生产装置对阀门的需求量越来越大，应用也越来越普遍。阀门是我们国民经济各部门不可缺少的流体设备之一，是石化工业中管道、设备中的重要组成件，其使用量大，涉及面广，品种复杂，它的质量的好坏、技术水品的高低都直接关系到装置的安全、平衡、长周期运行和各个使用部门的安全生产、长久发展和经济效益。
作者根据目前国内船用阀门的生产实际，进行调查研究，在充分掌握资料的基础上，实现了一系列阀门的参数化建模。作者以Solidwords软件为工具，运用参数化建模的理论实现了阀门的建模。参数化建模的实现可以减少同类产品的设计时间，缩短同类型产品的研发周期，降低了生产的成本。
本论文旨在对我国船用阀门的现代设计制造方法做一些尝试和探索，论文仅是理论方法上的研究，如要应用于生产实际还需要进一步分析研究。但本论文中提出的参数化设计思想，对我国各类生产行业探索和运用现代化设计方法相信会有一定的启发和推动作用。

Abstract This paper expounds the development of Marine valve field, including trends of development and directions of development. It stresses the important role of valve in all walks of life and researches the current situation of the valve at home and abroard. Directing to the problem of domestic research on valve with more time-consuming, consumables, puts forward the idea of parametrization design and manufacturing .
With the rapid development of the petroleum, chemical industry, production plant growing demand valve applications are becoming increasingly common..The valve is one of the various sectors of the national economy indispensable fluid equipmentit is an important component parts of the petrochemical industry in the pipes, equipment,it’s used a lot, Involves a wide variety of complex, Its quality, the technological level of products are directly related to device security, balance, long-term operation, the safe production of various user departments, economic efficiency and long-term development. The writer investigates and studies according to the current domestic production of valve and puts forward the idea of parametrization design and manufacture of the valve in full mastery of the material.The auther ues Solidworks software as tools,the use of parameterized modeling theory realizes the modeling of the valve.the implementation of parameterized modeling can reduce the design time of similar products,shorten the development cycle of the same kind of product ,reduce the cost of production.
This thesis aims to trying and doing some exploration methods of parametrization design and manufacture for the valve. This paper focuses on the study of theory, such as, applying to practical production needs further experiments and analysis research. But this paper presents the thought of parametrization design and manufacture, which will promote the valve exploration and utility of modern design method .
Keywords: check valve, parametrization modeling,marine valve
