Synchronous control device for pneumatic valves

The utility model discloses a pneumatic valve synchronous control device which comprises an electromagnetic valve, a distributor and a pneumatic valve which are sequentially connected in series. One electromagnetic valve is respectively communicated with two distributors which are arranged in parallel; a plurality of pneumatic valves are arranged, and each pneumatic valve is connected with the two distributors at the same time; and gas introduced into the electromagnetic valve can enter the pneumatic valve through one distributor or enter the same pneumatic valve through the other distributor. The electromagnetic valves communicated with the two distributors are arranged, and each distributor is connected with the pneumatic valves, so that an air source can enter one distributor every time after passing through the electromagnetic valves, and is synchronously conveyed to the pneumatic valves after being redistributed in the distributors, and therefore, a single electromagnetic valve can control the pneumatic
