ball_valve是什么意思_中英文、音标、

1. ball_valve是什么意思

ball valve是一种旋转式阀门，它的阀门体内部有一个球形活塞，通过旋转来流体的开关。它可以用来液体、气体或者粉状物质的流动，具有结构简单、密封性能好、使用寿命长等优点。在工业领域中广泛应用。

Ball valve is a type of rotary valve, which has a spherical piston inside the valve body to control the flow of fluid by rotation. It can be used to control the flow of liquid, gas or powder, and has the advantages of simple structure, good sealing performance and long service life. It is widely used in industrial fields.

2. 怎么读（音标）

英 [ˈbɔːl ˈvælv]

美 [ˈbɔːl ˈvælv]

3. 用法

Ball valve通常由阀门体、阀芯和传动装置组成。当阀芯旋转时，球形活塞也会随之旋转，从而改变流体的通道大小，实现开关。它可以用手动操作或者电动、气动等方式进行。

Ball valves are usually composed of a valve body, a valve core and an actuator. When the valve core rotates, the spherical piston also rotates, changing the size of the fluid passage to achieve switch control. It can be operated manually or controlled by electric, pneumatic and other methods.
