<P>PROBLEM TO BE SOLVED: To provide a portable auxiliary apparatus of a manually-operated valve opening/closing device usable for opening/closing operations of a plurality of valves. <P>SOLUTION: A handle rotating shaft rotation device 2 of the portable auxiliary apparatus 1 of the manually-operated valve opening/closing device 5 includes a spline socket 7 with two ends. The handle rotating shaft rotation device 2 further includes a reduction gear with an input/output shaft, an air motor with a rotating shaft, an air introducing opening for sending air to the air motor to rotate the air motor, and an air vent for venting the air sent in. Then, a first end of the spline socket 7 is coupled to a handle rotating shaft 6 of the manually-operated valve opening/closing device 5, while a second end of the spline socket 7 is coupled to an output shaft of the reduction gear, and an input shaft of the reduction gear is coupled to the rotating shaft of the air motor. An air cylinder includes an air discharge opening for discharging air, and an air hose 4 couples the air introducing opening of the handle rotating shaft rotation device 2 and the air discharging opening 21 of the air cylinder 3 together, via a regulator 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
