Three-dimensional storage material frame capacity detection system

The invention relates to the field of regulating valve production heat, in particular to a three-dimensional storage material frame capacity detection system which comprises a bottom cover matched with a material frame and a measuring box filled with a measuring medium. A plurality of piston cylinders are arranged on the bottom cover, and the extending ends of the piston cylinders are flush with the bottom of the bottom cover; a piston rod which stretches and retracts downwards is arranged in the piston cylinder, and the lower end of the piston rod is connected with a balance weight ball; the upper portion of each piston cylinder is further connected with a measuring branch pipeline, the other end of each measuring branch pipeline is connected with a measuring main pipeline, the other end of each measuring main pipeline is connected with the bottom of a measuring box, and an exhaust pipe is fixed to the top of the measuring box in a penetrating mode. The volume of the idle space of the material frame is indir
