电动球阀的构造原理

The construction principle of electric ball valve

电动球阀构造简略，只由少数几个零件组成，资料耗用省；体积小、重量轻、安装尺寸小 电动球阀结构图，驱动力矩小, 压力调节阀，操作简便、敏捷，只需旋转90°即可快速启闭；并且还同时具有良好的流量调节功效和封闭密封特性，在大中口径、中低压力的应用范畴，电动球阀是主导的阀门情势。阀门是蒙受内压的机械产品，因而必需具有足够的强度和刚度，以保证长期使用而不产生决裂或发生变形。

The electric ball valve structure simple, only by a few parts, material consumption; small volume and light weight, installation of small size electric ball valve structure, small driving torque, pressure regulating valve, simple and agile, can only rotate 90 degrees rapid opening and closing; and also has good flow regulating effect and closed the sealing characteristics, the scope of application in the large size, low pressure, electric ball valve is the dominant form of valve. The valve is subjected to internal pressure of mechanical products, and therefore must have sufficient strength and stiffness, in order to ensure long-term use without breaking or deformation.
