Breaker SF6 gas density relay rapid verification test device

The invention relates to a circuit breaker SF6 gas density relay rapid verification test device, which is characterized in that the device is directly screwed and connected with a vent hole of a three-way valve of a verified density relay through a movable internal thread connecting nut, the movement range of a movable connecting rod is adjusted, and during use, a movable handle can be directly held tightly by a hand; the deflation contactor moves forwards to push a movable bolt in a deflation valve port into the deflation contactor, a certain amount of gas is emitted, when the alarm pressure of the density relay is reached, the deflation contactor stops, a handle is loosened, and whether corresponding contacts of the density meter act or not can be directly tested; after the measurement is finished, the same method is continuously used for deflating again, the handle is released after the alarm value of lower pressure is reached, and whether the corresponding contact of the density relay acts correctly or no
