| description | The utility model provides a pneumatic valve control device which comprises an electromagnetic valve, an executing mechanism and a gas source. The pneumatic valve control device is characterized in that the gas source comprises a normal-pressure gas source and a high-pressure gas source, the pneumatic valve control device further comprises a first three-way reversing valve, a pressure reducing valve and a shut-off valve, wherein the first entrance end of the first three-way reversing valve is connected with the normal-pressure gas source, the second entrance end of the first three-way reversing valve is connected with the high-pressure gas source, the entrance end of the pressure reducing valve is connected with the exit end of the first three-way reversing valve, the exit end of the shut-off valve is connected with the entrance end of the pressure reducing valve, and the exit end of the shut-off valve is connected with the gas resource entrance end of the electromagnetic valve. The pneumatic valve control device can control over a failed valve continuously, effectively and in time, and relieve the failure processing pressure. |
