Gas storage facilities and piston anti-rotation device of the gas storage facility

摘要

The invention relates to maintaining the anti-rotation feature of the piston. For gas storage facility and a piston provided vertically movably to the reservoir cylindrical body, the interior of the reservoir body A1 A piston anti-rotation device 50, and project inwardly from the inner surface of the reservoir body and includes a ridge 51 extending in the vertical direction, and a pawl member 55 of a pair are placed on both sides of the ridge is provided on the piston. And, a slide member 56 provided in the pawl member is supported on the piston side to be slidable in the radial direction of the reservoir body, the piston anti-rotation device, the piston-side perpendicular to the moving direction of the slide member a rotary shaft 57 provided a lever 58 having a contact portion 58a which is movable into contact the slide member to the distal end side is rotatably supported by the rotating shaft, which is provided at the rear end side of the lever and a spring 59 which produces a pressing force to press the rib side pawl member to abut the slide member and the contact portion of the lever are.
