At present, in practical production application, a valve device which is widely adopted is a flat gate, and the flat gate has the problems that the resistance which needs to be overcome when the flat gate is closed is very large, and sometimes the situation that the flat gate cannot be closed is caused because of the blocking of a block material. To overcome this disadvantage, in combination with the bulk material characteristics, bar valves are also used in place of the flat gate in production. The bar valve is divided into a single bar valve and a group of bar valves, and has the advantages of simple structure, small opening and closing force and no blocking. However, the single rod valve needs manual operation, the rods are knocked into the chute or pulled out of the chute one by one, time and labor are wasted, and materials cannot be cut off and flow controlled in time, so that production is affected; the group bar valves are usually driven by a driving device to insert and extract the group bar valves, so that the defects of manual operation are overcome, but because the stroke of bars is usually larger than the width of a chute and the length of a pushing rod of the driving device is added, the group bar valves need to occupy a large horizontal space, which is a main reason for limiting the application of the group bar valves in production, because enough horizontal space is not usually reserved in the process design for arranging the group bar valves and the driving device thereof; in addition, as the extended length of the ganged bar valves increases, the counter-force of the ganged bar valve horizontal run increases accordingly, resulting in increased horizontal drag, which requires greater driving force, thereby increasing cost and energy consumption.
