Valve:
Valves are mechanical devices that control the flow of fluid and pressure within a system or process. Valves are used in a wide variety of applications, including controlling the flow of water, gas, steam, oil, and other liquids, as well as controlling the pressure of liquids and gases. Valves are available in a variety of materials and sizes, and can be operated manually or automatically.
气动球阀和气动半球阀有一些相似之处,但也有很大的差别。
首先,气动球阀是一种常用的闭口型活塞阀,它由一个封闭的球体、一个钢丝绳或弹簧等活塞内件组成,当活塞内件受到气体或液体的压力时,球体就会沿着一定的轨道旋转,从而控制流体的进出。
而气动半球阀是一种特殊的半球阀,它由一个半球形的阀芯和一个由气体或液体驱动的活塞组成,当活塞受到压力时,阀芯就会沿着一定的轨道滑动,从而控制流体的进出。
总的来说,气动球阀和气动半球阀是有很大区别的,它们虽然都可以用来控制气体或液体的流动,但它们使用的原理和结构是不一样的。
