一种气流附壁放空逆止元件
摘要：
本发明提出一种气流附壁放空逆止元件，包括控制腔体，所述控制腔体具有第一信号室和工作室，所述第一信号室通过第一信号出口和工作室连通，所述工作室具有第一侧壁和第二侧壁，第一侧壁和第二侧壁相对设置，所述第一信号出口的中心轴线与所述第一侧壁的距离小于所述中心轴线和第二侧壁的距离，所述工作室远离第一信号出口的一端设置有分流劈，所述分流劈位于所述中心轴线上。本发明提出的气流附壁放空逆止元件，是无主气源元件，在系统中起到控制单向流动的作用，实现气流信号控制。
摘要（英）：

The invention provides an empty non-return element of an airflow attached wall. The empty non-return element comprises a control cavity body, wherein a first signal chamber and a working chamber are formed in the control cavity body, the first signal chamber communicates with the working chamber through a first signal outlet, the working chamber is provided with a first side wall and a second sidewall which are oppositely arranged, the distance between the central axis of the first signal outlet and the first side wall is less than that between the central axis and the second side wall, a splitter is arranged on one end, which is far from the first signal outlet, of the working chamber, and the splitter is located on the central axis. The empty non-return element of the airflow attached wall is an element without a main air source and has the effect of controlling one-way flow in a system, so that the signal control over airflow is realized.
