Claims (1)

[Scope of Claim for Utility Model Registration] (1) The valve shaft of a valve whose valve shaft is rotated approximately 90 degrees or approximately 180 degrees to open, close, or switch piping is fixed to the valve and the valve is rotated. The connection mechanism with the output shaft of the actuator consists of a connecting tube A fixed to one of the valve stem or the output shaft and a connecting tube A that is slidable in the axial direction and non-rotatably attached to the other, and The cylinder shell and the connecting cylinder B have a clutch connection in which the connecting cylinder A and the connecting cylinder B are disconnected by moving the connecting cylinder A away from the connecting cylinder A, and are fixed to the valve shaft. Or, by attaching a manual operation tool to the attached connecting tube shell or the manual operation tool attachment part formed on the connecting tube A, the connection tube A and the connecting tube O can be distanced and the clutch connection can be removed. A manual operation device characterized in that the manual operation tool is operated manually in this state. (2) Attach a pin A to the axial position of the connecting cylinder A or the connecting cylinder A fixed or attached to the valve shaft, and attach a pin A at right angles to the pin A, and the pin A has a cam part. One end protrudes into the manually operated tool mounting part, and when the manually operated tool is mounted on the manually operated tool mounting part, the one end is pushed in, and the cam part pushes out the pin shell. 2. The automatic operating device according to claim 1, wherein the clutch is disconnected by separating the connecting sleeve and the connecting sleeve. (3) The manual operating device according to claim 2, wherein the pin A is pushed by the spring shell so that the one end portion protrudes into the manual operating tool mounting portion. (4) The manual operating device according to any one of claims 1 to 3, wherein the connecting sleeve is pushed in the direction of the connecting sleeve by a spring. (5) A connection mechanism between the valve shaft of a valve that opens, closes, or switches piping by rotating the valve shaft approximately 90 degrees or approximately 180 degrees and the output shaft of an actuator that is fixed to the valve and rotates the valve. is composed of a connecting cylinder A fixed to one side of the valve shaft or the output shaft, and a connecting cylinder A that is slidable in the axial direction and non-rotatably attached to the other side, and the connecting cylinder A and the connecting cylinder A are A clutch connection is made in which the connection between the connecting cylinder A and the connecting cylinder A is released by moving the connecting cylinder A away from the connecting cylinder A, and the connecting cylinder A or the connecting cylinder A is fixed or attached to the valve shaft. By attaching a manual operating tool to the manual operating tool mounting portion formed on the connecting tube A and moving the grip portion of the manual operating tool upward or downward, the connection tube A and the connecting tube O are moved away from each other. A manual operating device characterized in that the clutch is disconnected and the manual operating tool is operated in this state. (6) The manual operating device according to claim 5, wherein the connecting tube A is pushed in the direction of the connecting tube A by a spring. (7) The manual operating device according to any one of claims 1 to 6, wherein the connecting sleeve is fixed to the valve shaft, and the connecting sleeve is attached to the output shaft. (8) The manual operating device according to any one of claims 1 to 7, wherein the connecting tube A and the connecting tube B are connected in a clutch manner by a protrusion provided on one side and a groove provided on the other side.
