摘要本文主要是对船用通海阀进行系列化设计。船用通海阀主要是由阀体、阀杆、阀盖、阀盘等一系列构件组成。其内部结构主要由伞状手轮控制，实现通海阀的开关闭合，从而能够切断或者打开介质流通通道，控制船外介质与船内的交换。通海阀广泛地应用于船舶制造工业，它是控制流体流通的枢纽。56687
在产品设计和开发过程中，零部件的标准化、通用化、和系列化能够有效地提高产品的设计质量，也是缩短产品开发周期的有效途径。系列化产品的基础件通用性比较好，它能根据市场的动向和消费者的特殊要求，采用发展变型产品的经济合理办法，机动灵活地发展新品种。所以系列化的产品既能及时满足市场的需要，又可以保持企业生产组织的稳定，同时还能最大限度地节约设计力量，因此产品系列化是搞好产品设计的一项重要原则。企业如果想要更好的发展前景，更开阔的市场，那么就必须按照产品系列化的要求进行设计，对没有系列型谱的产品要逐步形成系列型谱，而对已有系列型谱的应严格按照系列型谱进行设计，保证新产品按系列发展。

Abstract
This paper mainly designs a series of sea valves for marine use. Marine sea valve is composed of valve body, valve stem, valve cover, valve disc and a series of components. Its internal structure is mainly controlled by the umbrella handle, the valve is closed, so as to cut off or open channel, control of the ship water out of the ship. The valve is widely used in the shipbuilding industry, it is the switch to control the fluid flow.
In product design and development process, standardization, generalization, and parts of the series is to improve product design quality, shorten the product development cycleand effective way. Products of the series basic pieces of good versatility, it can according to the special requirements of trends and consumer market, the reasonable way of economic development product variants, flexible to develop new varieties, which can meet the needs of the market, but also to maintain the stability of production organization of enterprises, but also to maximize the conservation of the design strength, this series of products is an important principle in product design. Enterprises must be designed in accordance with product serialization requirements, not on the series spectrum to gradually form a series, the series spectrum should be strictly in accordance with the series design, ensure new product according to a series of development.
Keywords: Gate valve, structure, series
