摘    要:旋塞阀是用带通孔的旋塞作为启闭件,通过旋塞与阀杆的转动实现启闭动作的一种阀门。阀杆旋转,使旋塞开口与阀门的流道形成了大小不同的流通截面,以此来改变流体的流量大小。研究了旋塞阀旋塞旋转时形成的流通截面面积的计算方法。旋塞转过角度不同,打开的流道截面形状不同,很难快速准确计算出相应面积,对流体流量的控制难以把握。提出基于SolidWorks软件三维建模方式,将旋塞流道与密封衬套流道实体化,利用流道模型的装配体模拟流道面积的变化,运用布尔运算求得两流道模型共同实体,计算旋塞阀旋塞转过不同角度时流道截面积方法,计算速度快,结果准确。

关 键 词:旋塞阀  圆锥形旋塞  流道截面面积  SolidWorks三维模拟

Abstract:The plug valve is one in which the cock body with through hole is used as the disc to achieve the on/off by the rotation of the cock body and the valve stem.The valve stem rotates to form a different size of flow cross section of the plug opening and the flow passage of the valve,thus changing the flow rate of the fluid.In this paper,the calculation method of the flow cross-sectional area of the plug valve cock is studied.The cock body has different angles of rotation,and the cross-section shape of the opened flow channel is different.It is difficult to calculate the corresponding area quickly and accurately,and it is hard to control the flow rate.This paper proposes a three-dimensional modeling method based on SolidWorks software,which is used to materialize the flow path of the cock and the sealing bushing,and the change of the flow channel area is simulated with the assembly of the flow path model.The Boolean operation is used to obtain the common body of the two-channel model,and the cross-sectional area of the flow channel is calculated at the different angles and the speed of the aperation is fast and the result is accurate.
Keywords:plug valve  conical cock  cross-sectional area of flow channel  SolidWorks 3D simulation
