Device and method for measuring detonation velocity of emulsion explosive under static pressure condition

The invention relates to a device and a method for measuring the detonation velocity of an emulsion explosive under a static pressure condition, one end of a pressure pipe of the measuring device is connected with an upper end cover of the pressure pipe, the other end of the pressure pipe is connected with a lower end cover of the pressure pipe, and the lower end cover of the pressure pipe is provided with a through line connector with a sealing ring; a probe is bundled on a tested emulsion explosive package, the tested emulsion explosive package is arranged in a pressure pipe, a signal transmission wire and a digital electronic detonator wire are conducted from the pressure pipe through a sealing ring wire connector and extend out of the pipe, and the signal transmission wire is led out of the pressure pipe and connected to a detonation velocity instrument. And a digital electronic detonator lead is led out from the pressure pipe and is connected to a digital electronic detonator initiator. By adopting the d
