The utility model belongs to the technical field of valve driving, and particularly relates to a valve driving circuit of a launch canister. The circuit comprises a signal acquisition module for acquiring an air pressure signal in a launch canister; the judgment module is used for converting the air pressure signal into air pressure information, comparing the air pressure information with standardair pressure information, sending an inflation/deflation valve starting signal to the driving module according to a comparison result, and sending a control signal to the driving module; and the driving module is used for receiving a control signal to enter a conduction state, driving the inflation valve to be started according to the inflation valve starting signal or driving the deflation valveto be started according to the deflation valve starting signal. The drive circuit is simple in structure and good in drive signal stability. 本实用新型属于阀门驱动技术领域，特别是涉及一种发射筒的阀门驱动电路。所述电路包括：信号采集模块，采集发射筒内的气压信号；判断模块，将所述气压信号转换为气压信息，并比较所
