一种能够防止粉料倒吸的供气系统
摘要：
本实用新型公开了一种能够防止粉料倒吸的供气系统，包括供气管路、阀门、连接管路及自动调压装置，供气管路设有至少两个出气口，出气口处装有阀门，阀门上设有连接管路，安装在供气管路上的自动调压装置包括电动阀、控制器、第一压力传感器及第二压力传感器，电动阀的开启程度和第一压力传感器与第二压力传感器之间的压力差成正比，能够防止当其他出气口突然打开时，供气管路内气压突然减小，而造成正在供气的连接管路内粉料倒吸的现象发生。
摘要（英）：

The utility model discloses an air supply system capable of preventing powder from being sucked back. The device comprises an air supply pipeline, a valve, a connecting pipeline and an automatic pressure regulating device, the air supply pipeline is provided with at least two air outlets; valve mounted at air outlet, connecting pipeline is arranged on valve, the automatic pressure regulating device installed on the air supply pipeline comprises an electric valve, a controller, a first pressure sensor and a second pressure sensor. The opening degree of the electric valve is in direct proportionto the pressure difference between the first pressure sensor and the second pressure sensor, and the phenomenon that when other air outlets are suddenly opened, the air pressure in the air supply pipeline is suddenly reduced, and consequently powder in the air supply connecting pipeline is sucked back can be prevented.
