摘要外螺纹截止阀是船舶领域中使用比较多的一种典型的阀，在海洋船舶中具有广泛应用。但由于各种船只所需要的外螺纹截止阀的型号、规格存在差异，因此外螺纹截止阀的设计、生产仍以定制为主，其设计效率低。随着三维CAD技术在机械领域的不断应用，外螺纹截止阀的设计也在向、自动化、智能化方向发展。52562
本次毕业设计的目的是设计外螺纹截止阀并进行参数化，论文首先提出了外螺纹截止阀设计所需解决的问题，然后进行强度的计算。当完成这些后，可以对其进行建模然后参数化。在完成外螺纹截止阀的参数化后，只要输入外螺纹截止阀的相应参数，系统就会自动完成外螺纹截止阀的实体的图形。这种方法的整个设计界面友好，且操作方便，设计出来的零件也是一个系列化的满足各种匹配要求，精度和强度也能满足设计的要求。论文最后总结了外螺纹截止阀参数化设计的特点，并展示部分三维图。

Abstract Male valve is in the use of marine areas are more of a typical valve, marine vessels has wide application. However, due to a variety of vessels needed Male valve models, specifications differ, so externally threaded globe valve design, production is still mainly developed, designed and inefficient. With the three-dimensional CAD technology in the field of continuous application of mechanical, Male valve design also to, automation, intelligent direction.
The purpose of this paper is to design and conduct externally threaded valve parameterization, the paper first proposed Male valve design required to solve the problem, then the strength calculations.Upon completion of these, you can be modeled and parameterized. Male valve complete parameterization, simply enter Male valve corresponding parameters, the system will automatically Male valve graphical entities. In this way the overall user-friendly design, and easy to operate, the part is designed to meet a series of various matching requirements, precision and strength can meet the design requirements. Paper concludes with male thread stop valve parametric design features, and show some three-dimensional map.
Keywords: Valve parametric Male valve corresponding parameters
