Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire-fighting facility detection, in particular to air-tightness detection equipment for fire-fighting facilities. Background Art
[0002] Fire-fighting facilities are equipment and facilities installed in buildings for the prevention and extinguishing of fires. Effective use of fire-fighting facilities can create favorable conditions for fire fighting and personnel evacuation, thereby reducing property losses and casualties caused by fires. Fire-fighting facilities include smoke exhaust pipes, fire-proof roller shutter doors and windows, gas masks, fire extinguishers, water pipes and other hardware facilities. Among them, fire extinguishers are tanks filled with fire-extinguishing materials.
[0003] The air tightness of the fire extinguisher tank can determine whether the fire extinguisher can be used effectively. Since the fire extinguisher tank undergoes the processes of tank body rolling and longitudinal seam welding, upper and lower heads, and tank mouth valve seat welding, the welding seams may not be airtight. When the air tightness of the tank needs to be tested, the water bath method is currently used for testing. The tank is inflated and placed in water, and the human eye is used to observe whether bubbles are generated. If the leakage is small, the bubbles are small and not dense, and are not easy to be observed by the human eye. The test results of this detection method are not accurate enough. Utility Model Content

The output end of 7 is provided with an edge sealing cover 5 which cooperates with the fixed sealing seat 4. The capping mechanism includes an electric cylinder 2 8 fixedly arranged on the upper end of the top plate 3. The output end of the electric cylinder 2 8 is provided with a capping cover 6 which penetrates the top plate 3 and cooperates with the edge sealing cover 5 and the fixed sealing seat 4. The upper end of the base 1 is provided with a control button 10 which is electrically connected to the electric cylinder 1 7 and the electric cylinder 2 8 respectively, so as to facilitate the control of the electric cylinder 1 7 and the electric cylinder 2 8. Sealing strips are adhered to the edges of the fixed sealing seat 4, the edge sealing cover 5 and the capping cover 6.
[0023] Through the above structure, the top cover 6, the side cover 5, the bottom cover 9 and the fixed sealing seat 4 can be assembled into a sealed whole. How to perform airtightness detection on the fire extinguisher tank body? The specific structure is as follows:
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixed sealing seat 4 and the edge sealing cover 5 are provided with a cavity 13 that cooperates with the fire extinguisher tank body, the top cover 6 is provided with an air pressure detection sensor 12 that cooperates with the cavity 13, the bottom plate 9 is provided with a socket 14 that extends into the cavity 13 and cooperates with the tank mouth of the fire extinguisher tank body, the socket 14 is provided with an air inlet 15, and the air inlet 15 is connected to the output end of the air pump through a pipeline, and a numerical display screen 11 electrically connected to the air pressure detection sensor 12 is fixedly connected to the relatively arranged vertical poles 2, so as to facilitate the observation of the numerical value detected by the air pressure detection sensor 12.
[0025] Through the above structure, the air tightness test of the fire extinguisher tank in the cavity 13 can be performed.
[0026] Embodiment 2

[0028] The above structure makes it easy to disassemble and assemble the capping cover 6.
[0029] During the specific implementation of the utility model, when it is necessary to conduct an air tightness test on the fire extinguisher tank, the tank is first inverted and its tank mouth is plugged into the socket, and then the electric cylinder 1 and the electric cylinder 2 are opened, and the electric cylinder 1 drives the edge sealing cover to move toward the fixed sealing seat until the edge sealing cover is in close contact with the fixed sealing seat, and the electric cylinder 2 drives the top sealing cover to move toward the edge sealing cover and the fixed sealing seat until the top sealing cover is in close contact with the upper end surface of the fixed sealing seat and the edge sealing cover, at which time the tank is located in the cavity, and the air pressure detection sensor in the top sealing cover can detect the air pressure data in the cavity, and the air pressure value can be displayed on the numerical display screen;
[0030] Then blow air into the tank through the air inlet. If the tank leaks, the gas will leak into the cavity, thereby affecting the air pressure inside the cavity. The air pressure value will change, that is, the air tightness of the tank does not meet the requirements. If the air tightness of the tank is good, the air pressure value will not change, so the test result is more accurate.
