Embodiment Construction

[0043] Embodiments of the present invention will be described with reference to the drawings.

[0044] exist Figure 1 to Figure 6 In the manual operation device for the fluid pressure driving device produced by the implementation state of the present invention, firstly, the Figure 10 The illustrated fluid pressure drive unit is described centering on the manually operated unit. What Fig. 7 and Fig. 8 show is pneumatic-hydraulic driving device 200. It is used for actions set in such as Figure 6 Valve 300 in line as shown. Although the appearance and shape are different, it has the same Figure 6 The same mechanism is shown for the air cylinder or hydraulic drive 200 .

[0045] An example of the pneumatic-hydraulic driving device 200' is as shown in Figure 7 and Figure 8, the piston rod 204' in the 203' is repeatedly moved through the brake rod seat 202' and the valve 300' on the pipeline is moved repeatedly. The switch, the structure that can make the valve stem 6 rota...

Abstract

The invention has a free-rotating wormwheel mounted on the valve stem, a worm engaged with the wormwheel and an aid speed-reducing device. On the wormwheel is mounted an antifriction coupling, on itsopposite is mounted a drive antifriction coupling rotating with the valve stem. When the bite teeth of the two couplings are disengaged, the hand operation is used for rotating the aid handle, the worm and the wormwheel to the valve stem, so that the valve can be opened and closed.

Description

technical field [0001] The present invention relates to a manual operation device of a fluid pressure drive device with a control valve, which uses air pressure such as oil pressure or air pressure as a power source. In place of this hydraulic drive unit, manual operation is provided. Even if the pump on the device cannot be driven by fluid pressure, the valve stem can be operated manually, and the rotation of the valve stem generated by the manual operation device and the action of the fluid pressure drive device can work without interfering with each other. A fluid pressure actuator of this character is provided for a manually operated device. Background technique [0002] As a typical cylinder-type driving device of a fluid pressure driving device, in order to actuate a valve in a pipeline, there is one driving device described in a patent document (Kokai Publication No. Hei 8-54083). In this kind of driving device, the switching valve supplies the supply oil through th...
