MEDIUM-SIZE BULK CONTAINER AND VALVE OPENING/CLOSING DEVICE THEREFOR

摘要

The present invention discloses a valve opening/closing device for an intermediate bulk container. the container comprises a base, side plates, and a valve provided on the base. Wherein the valve opening/closing device comprises a handle, a motion-transferring device, and a valve opening/closing mechanism, wherein the handle is mounted on the side plate and connected to the motion-transferring device, and the motion-transferring device is used to transfer the force applied on the handle to the valve, so as to open or close the valve. For the valve opening/closing device of the present invention, the operating handle is provided at an appropriate position at the side plate of the container, thereby avoiding bending over or squatting on the ground, etc when opening or closing the valve, facilitating use. In addition, the operating moment can be adjusted through adjusting the transmission ratio of the motion-transferring device, which makes it easy to control the operating force.
