混凝土泵S型管阀程序设计

分配阀是混凝土泵中的一个关键部件，工作中它与两个混凝土缸交替对接，完成混凝土的吸料和排料功能，它在工作中的可靠性是泵送混凝土时使混凝土能顺畅流动到达浇注点的保证，如何设计出结构合理、性能良好的分配阀是目前国内外科研人员研究的重点．当前国内外混凝土泵中广泛使用的S型管阀，从面向程序对象设计的原理出发，利用VC 对其进行可视化设计，可计算和绘制出不同排量混凝土泵中使用的不变径S型管阀的基本尺寸和图形，为混凝土泵S型管阀的设计提供了一种全新的方法．

Design of the S-type of the tube valve for concrete pump with VC++ program

The distributing valve is the crucial element in the concrete pump truck, and it connects with two concrete cylinders alternately at work, through which, the process of extract and distract of concrete can be finished. This can guarantee that the concrete is delivered to the work position glibly when concrete is also pumped. At present, the sound configuration and performance of the distributing valve has long been the focus of the design. In this paper, according to the theory of OOD and VC++ program, the problem of the visual design of S-tube widely applied to concrete pump truck is discussed. Through discussion, the calculation of essential dimensional parameters and drawing of constant diameter S tube valve used in different sendout concrete pump truck are worked out. These provide a new approach for S tube valve design.
