Abstract
PURPOSE: To improve reliability of a valve opening indicator readily and unexpensively by means that a turning motion of a handle is converted into a parallel motion coaxial with a stem by use of a slide rod whose motion at its conical end is changed into a swing motion of a valve opening indication needle by the effort of a lever.
CONSTITUTION: As a valve handle is turned for opening a valve, a stem 3 and a disc 4 united with it come turning out. Simultaneously a disc 2 coupled with the groove of the disc 4 is accompanied with its out motion, which is united with a slide rod 1. The lower end B of a lever 6 is contact with a cone part A of the slide rod 1 so that said lower end B turns clockwise around a fulcrum 7, while the upper end C turns counterclockwise by a load of a spring 8. As a result an opening indication needle 9 fixed on a turning element 11 whose high spot 12 is joined with a notch formed in the upper end C of the lever 6 swings noticeably. The swing can be seen easily to confirm the grade of valve openings.
