description The utility model relates to a fire extinguishing performance test device for an ultrafine powder fire extinguishing agent. The device comprises a gas-powder mixing part consisting of a gas flowmeter, a gas-powder mixer and a plug, a screw propulsion powder conveying part consisting of a propulsion screw rod, a screw rod sleeve, a trough, a powder pot, a sealing cover, a driving motor and a first driving controller, a powder stirring part consisting of a stirring paddle, a stirring motor and a second driving controller, and a fire extinguishing test part consisting of a test container, a combustion cup, an adjustment valve and a fuel storage pot. According to the fire extinguishing performance test device, the problem that continuous and stable feeding is affected by facts that the ultrafine powder fire extinguishing agent is easy to arch and powder around the propulsion screw rod is easily impracticable or hollowed is solved; the fire extinguishing performance test device has the outstanding advantages of co
