Indicate the opening direction on the drawing, which can be represented using arrows. The arrow indicates the direction in which the blind flange should be opened; it can be drawn directly on the drawing, or textual instructions can be added above the drawing. Additionally, the direction of opening can also be indicated with a specific symbol in the legend. The specific method of marking can be determined according to the design specifications and requirements of the drawing. .
