Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment detection, in particular to an air tightness testing device for gas fire-extinguishing equipment. Background Art

[0002] Gas fire extinguishing equipment is widely used in places such as data centers and communication base stations where water fire extinguishing is not suitable. Its working principle is to extinguish fires by releasing fire extinguishing gas. Therefore, the air tightness of the equipment is crucial to the fire extinguishing effect.

[0003] However, existing air tightness testing methods usually require manual immersion of gas fire extinguishing equipment in a water tank for pressurized inflation testing. This not only increases the risk in operation, but the refraction effect of water can easily cause inspectors to be unable to accurately determine the leakage point of the equipment, thereby affecting the accuracy of the test.

[0004] The utility model installs a colored smoke generator on the top of the air tightness detector, which can produce colored smoke and inject the colored smoke into the fire extinguishing equipment body under pressure through a conduit, and detects the leakage position by observing the escape point of the smoke, which not only can quickly find the leakage point, but also can avoid the refraction effect of water that makes it impossible for the inspector to accurately judge the leakage point of the fire extinguishing equipment body. At the same time, a screw rod is connected by threading the middle part of the support frame fixed on the support plate, and a splint is fixed on the adjacent side of the screw rod. The fire extinguishing equipment body can be fixed by adjusting the screw rod, so that the inspector does not need to manually hold the fire extinguishing equipment body to stabilize it, avoiding the possible injury to the inspector when pressurizing the fire extinguishing equipment body with gas.
