The utility model provides a valve type expansion wave artillery which comprises an artillery body and an artillery tail, an explosive chamber penetrates through the artillery tail in the length direction of the artillery body, one end of the explosive chamber is communicated with a bullet channel, a gas injection opening for injecting high-temperature gunpowder fuel gas is formed in the other end of the explosive chamber, and a latch body control mechanism and a piston control mechanism are arranged on the artillery tail. The left latch body and the right latch body are closed, so that the latch body control mechanism is in a locking state, and the piston piece pushes the left connecting rod or the right connecting rod, so that the locking state of the latch body control mechanism is released. According to the valve type expansion wave artillery, by controlling the opening time of the latch body, the recoil impulse and recoil force of artillery shooting are reduced on the premise that the initial speed and t
