Check Valve(止回阀)

定义
Check valve(止回阀)是一种只允许流体单方向流动的阀门,常用于防止流体回流。它通过自动关闭机制来防止流体倒流,通常被安装在管道系统中。

音标
/tʃɛk vælv/

翻译

Check valve:止回阀

读音

Check:[tʃɛk]("ch"发音类似于汉语拼音的“q”)

Valve:[vælv]("a"发音像“æ”,即“cat”中的“a”音)

用法
Check valve用于各种液体和气体流动系统中,尤其是在防止逆流造成设备损坏或提高系统效率时。它可以是机械型(通过弹簧或重力关闭阀门)或者自力型(通过流体动力关闭阀门)。常见的使用场景包括水泵、管道系统、暖通空调系统等。
