发明名称 REVERSE ROTATION OPERATING DEVICE FOR VALVE
摘要 PROBLEM TO BE SOLVED: To efficiently and easily attach valve operation shafts of valve cases to a plurality of types of valves having different heights from a fit connection position of a reverse transmission shaft to a clamp fixing position of a clamp fixing means in a state of being capable of surely conducting a reverse operation. SOLUTION: The reverse rotation operating device is provided with an attachment frame 3 externally mountable to a valve case 2 at which a valve operation shaft 1 protruding upward is provided, a reverse rotation operation body A having the reverse transmission shaft capable of fit to and connected with the valve operation shaft 1 in an integrally rotatable manner and the reverse rotation operation shaft interlocking with the transmission shaft via a reverse rotation mechanism and a fixing connection means B for fixing and connecting the reverse rotation operation main body A and the attachment frame 3. The attachment frame 3 is provided with the clamp fixing means C clamped and fit to the valve case 2 and the clamp connection means C is provided with an attachment interval change means D for changing a vertical attaching interval of the attachment frame 3 and the reverse rotation operation main body A.
