在调节阀普遍应用于各种大型液压机械的今天，设计一种调节精确且工作安全可靠的调节阀成为阀门制造业的热点。
本文所设计的汽轮机倒车阀，属于调节阀，通过手轮转动控制阀杆的升程，从而实现对管道内流体流速的控制。比起传统的阀门，该装置采用套筒结构，减小了阀杆的振动，提高了阀门的稳定性。同时该阀门设计摒弃了传统的粗估绘制阀瓣形面的方法，采用理论计算并且通过特定的方法绘制阀瓣形面，如此可以较精确的控制调节阀的工作状态，此种方法对于调节阀的设计以及应用具有重要指导意义。
本文在介绍了调节阀的国内外发展现状的基础上，分析了调节阀的工作原理，而后设计了调节阀的阀体、阀盖、阀杆、阀碟以及阀座等主要零部件，确定调节阀的流量曲线以及绘制阀瓣形面，并通过PRO/E软件完成主要零部件的三维建模并且完成装配，验证了系统结构的合理性和有效性。
哪位高手大神能帮着翻译一下啊

On the regulating valve is commonly used in a variety of large-scale hydraulic machinery today, design a kind of adjustment is precise and safe and reliable operation of the regulating valve valve manufacturing industry become hot.

In this paper the design of reversing valve of steam turbine, which belongs to the regulating valve, through the hand wheel rotation control valve lift, thus realizing the pipeline fluid flow control.Compared with the traditional valve, the device adopts a sleeve structure, reduce the vibration, improve the stability of the valve.At the same time, the design of the valve to abandon the traditional rough estimation drawing disc shaped surface by theoretical calculation method, and through the specific method of drawing disc shape, so can be precisely controlled regulating valve working condition, this method for adjusting valve design and application has important guiding significance.
Based on the introduction of the regulating valve development at home and abroad on the basis of the status quo, analysis of the control valve of the working principle, then the design of regulating valve body, valve cover, valve rod, valve plate and valve seat and other main parts, determining the flow control valve and valve curve drawing surface, and through PRO/E software to complete the main parts 3D modeling and assembly, validate the reasonableness and effectiveness of system structure.
