半球阀与v球阀区别在哪 阀门英文

半球阀与v球阀区别在哪：

1. 半球阀：半球阀是一种具有半球形闭锁元件的闸阀，当阀杆转动到一定角度时，半球形的闭锁元件可以改变流通的方向，从而调节介质的流量。

2. V球阀：V球阀是一种机械阀门，其核心部件是一个圆形的V形球体，通过旋转球体来调节介质的流量，旋转角度越大，流量越大。

两种阀门的区别主要在于：

1. 半球阀是一种具有半球形闭锁元件的闸阀，而V球阀是一种机械阀门，其核心部件是一个圆形的V形球体。

2. 半球阀调节流量时，需要改变阀杆的转动角度；而V球阀调节流量时，需要改变球体的旋转角度。

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.
