<p>A safety flow guide protection device comprises a body having a flow guide device through which high pressure air flows; the flow guide device coated with a protecting layer; a safety releasing section formed at a surface of the flow guide device, the flow guide device being a hollow structure; a rear side of the flow guide device being formed as a combining opening; an air grid unit being received in the flow guide device at a side opposite to the combining opening; the air grid unit having a brake air valve for controlling high pressure air. When the flow guide device is communicated, the brake air valve is not compressed by the high pressure air so that the air grid unit is opened for allowing the flowing of the high pressure air; and vice versa.</p> |
