Pneumatic valve drive of nuclear power station

The utility model discloses a pneumatic valve drive of nuclear power station, it includes: compressed air source, with the blasting subassembly of compressed air source through first tube coupling, and pass through the pneumatic valve of second tube coupling with the blasting subassembly, wherein, systematic valve open signal is come from to direct receipt of blasting subassembly. Compared with the prior art, the utility model discloses pneumatic valve drive of nuclear power station has following advantage: at first, adopting and blowing up subassembly and the device that the pneumatic valve made up, only blow up the subassembly and blown up after the device is by the trigger action, the availability factor that has improved the device telescopes the change scope of dingus, secondly, adoptthe less blasting subassembly of size, reduced splash and the reduce cost after the blasting, it is last, simplified control mode to the reliability has been improved through redundancy design. 本实用新型公开了种核电站气动阀驱动装置，其包括：压缩空气源；
