The invention relates to the technical field of aircraft component testing, and discloses a fire extinguisher diaphragm backpressure testing device and method, and the device comprises a gas cylinder, an electric detonator, and a connection tool which is connected between the gas cylinder and the electric detonator and is used for simulating a fire extinguisher cavity. The connecting tool comprises a three-way piece, and the three-way piece comprises a release port used for being connected with an electric detonator, an inflation port used for being communicated with a gas cylinder and a testing port used for being connected with a pressure sensor for pressure testing. A diaphragm fixer used for fixing a diaphragm is connected in the inflation port; a distance adjusting part used for adjusting the distance between the electric detonator and the diaphragm is connected into the release opening. According to the invention, the working condition of the diaphragm under the real back pressure can be accurately test
