Abstract
PURPOSE: To indicate the condition of the valve after releasing pressure by providing the indicating panel equipped with the claw of which clamping with the stopper, which is linked with the pressure receiving plate, is released when pressure is released.
CONSTITUTION: When the pressure receiving plate 16 is pushed upward by the hydraulic pressure to make a clearance between the plate 16 and the O ring 15, the pressure receiving plate 16 goes up drastically until the guide 19 touches the stopper 17 of the cover 4 as the pressure receiving area suddenly extends as large as the outer diameter of the O ring 25. Then, the top of the working rod 11 pushes up the end of the stopper 9 to turn the stopper 9 in the anticlockwise direction resisting the spring which is not shown in the diagram, and the clamping of the indicating plate claw 7a by the stopper is released to turn the indicating plate 7 anticlockwise until it touches the stopper 5 by the spring 24. By this constitution, it is indicated by the displacement of the indicating plate 7 to the outside that the pressure releasing valve is working. On the other hand, the movement by the working rod 11 of the pressure receiving plate 16 during releasing pressure is indicated by the gap between the movable indicator 8 and the fixed indicator 21.
