一、进口承插焊球阀概述

进口承插焊球阀（美国威盾VTON），Socket weld ball valve，也叫三片式承插焊球阀，承插焊不锈钢球阀，承插焊三片式球阀，是指采用承插焊的连接方式，用带有圆形通道的球体作启闭件，球体随阀杆转动实现启闭动作的阀门，其启闭件是一个有孔的球体，绕垂直于通道的轴线旋转，从而达到启闭通道的目的。

Socket weld ball valve (VTON), also known as three piece socket weld ball valve, socket weld stainless steel ball valve, socket weld three piece ball valve, refers to a valve that uses a socket weld connection method, uses a ball with a circular channel as the opening and closing part, and the ball rotates with the valve stem to achieve the opening and closing action. The opening and closing part is a perforated ball that rotates around the axis perpendicular to the channel, thereby achieving the purpose of opening and closing the channel.
