Description

Technical Field

[0001] The present invention relates to the technical field of fire safety, and in particular to an air tightness detection device for a fire extinguisher. Background Art

[0002] As an important fire-fighting equipment, the air tightness of fire extinguishers is directly related to the fire extinguishing efficiency. If there is an air tightness problem in the fire extinguisher, the internal fire extinguishing agent and driving gas may leak, resulting in a pressure drop. When a fire occurs, the agent cannot be sprayed normally to extinguish the fire, endangering the safety of life and property. Therefore, it is necessary to conduct air tightness testing on the fire extinguisher to detect and deal with leakage problems in time. This is a necessary measure to ensure that the fire extinguisher is in good standby condition.

[0003] Currently, the air tightness test of fire extinguishers generally adopts the water immersion test method. When the fire extinguisher needs to be tested, the staff needs to lean over and reach into the water tank, grab the fire extinguisher to be tested underwater and adjust its position. After completing the test, the fire extinguisher needs to be laboriously taken out of the water. This static water environment not only makes the removal process cumbersome, but is also easily affected by the depth of the tank and the water pressure, increasing the difficulty and time cost of operation. In addition, the metal parts of the fire extinguisher are prone to rust due to long-term contact with water. For this reason, we proposed a fire extinguisher air tightness detection device.
