Claims

[Claims for Utility Model Registration] A manual valve having a spindle, a handle fixed to the spindle, and a valve that opens and closes by rotating the handle around the axis of the spindle and moving it in the axial direction. In the valve erroneous operation prevention mechanism for preventing erroneous operation between the plurality of manual valves, the valve mechanism includes a plurality of pins provided for each of the handles of the plurality of manual valves and extending parallel to the axial direction of the spindle; a plate in which spindle holes and pin holes for inserting the spindles and pins of the manual valve, respectively, are drilled in the same number of holes as the manual valves, and the spindles are slidably inserted into the spindle holes; and a stopper that can be fixed at any position on the spindle for each of the plurality of manual valves and stops the plate on the handle side by moving the spindle in the axial direction, and each of the manual valves is operated according to a predetermined operating procedure. erroneous operation between the plurality of manual valves is prevented by mechanically locking the manual valves by inserting the pin provided on the handle of the plurality of manual valves into the pin hole in the plate. A mechanism for preventing erroneous valve operation.
