Title:
OPENING STOPPER STRUCTURE OF ROTARY VALVE, OPEN/CLOSE LOCKING STRUCTURE OF ROTARY VALVE, AND ROTARY VALVE
Document Type and Number:
Japanese Patent JP2023111163
Kind Code:
A
Abstract:
To provide an opening stopper structure of a rotary valve, open/close locking structure, and a rotary valve capable of certainly regulating an opening within a range of a predetermined angle without influencing on the ground at all, even with a simple structure.SOLUTION: An opening stopper structure of a rotary valve is equipped with a stopper member 40 that rotates so as to coaxially interlock with a stem 10 rotating a valve body 8 in a body 2, a movable member 50 capable of coaxially rotating with the stem 10, and a positioning portion 31 that is provided on the body 2, and regulates a start point and a finish point of a rotation range of the movable member 50 at a positional relationship less than a predetermined angle. The stopper member 40 regulates the rotation range relative to the movable member 50. By combining the rotation range to the positioning portion 31 of the movable member 50 and the rotation range relative to the movable member 50 of the stopper member 40, an operation range of the rotary valve is rotation-regulated at a predetermined angle.SELECTED DRAWING: Figure 5
