Description

Technical Field

[0001] The utility model relates to the field of fire protection pipeline detection, in particular to a fire protection pipeline air tightness detection device. Background Art

[0002] Firefighting pipes refer to pipe materials used in firefighting to connect firefighting equipment and devices and to transport firefighting water, gas or other media. Due to special needs, the thickness and material of firefighting pipes have special requirements, and they are sprayed with red paint to transport firefighting water. A Chinese patent discloses a firefighting pipe air tightness detection device (authorization announcement number CN217560877U). The patent technology discloses a firefighting pipe air tightness detection device, including a firefighting pipe, the end of which is fixedly connected with a mounting flange, and the end of which is sleeved with a sealing frame. The advantages of the utility model are: when it is necessary to test the air tightness of the fire-fighting pipe, the sealing frame is opened by rotating the rotating shaft, and it is sleeved on the end of the fire-fighting pipe and locked by the lock buckle to complete the installation of the sealing frame. When it is necessary to install a pressure device, a telescopic air pump is installed at the threaded opening, and the sealing frame at the other end of the fire-fighting pipe is closed by the end cover, so that the device can close both ends of the fire-fighting pipe, and apply air pressure inside the telescopic air pump box to detect the air tightness of the fire-fighting pipe. By setting threaded holes and screws on the sealing frame, the operator can adjust the depth of the screw extending into the sealing frame by turning the knob, thereby adjusting the limit plate. The patented technology solves the shortcomings of the existing fire-fighting pipe air tightness detection device: the existing fire-fighting pipe air tightness detection device has a complex structure, is inconvenient to adjust the detection position, and can only adjust the pipe to be inserted into the device for detection.

[0003] However, in the prior art, the inner diameters of fire-fighting pipes are different, resulting in gaps during air tightness testing of the fire-fighting pipes, resulting in poor sealing. It is necessary to solve the problem in the prior art of having good sealing during air tightness testing of fire-fighting pipes while being applicable to fire-fighting pipes of different inner diameters.

[0004] Therefore, those skilled in the art provide a fire protection pipe air tightness detection device to solve the problems raised in the above background technology. Utility Model Content
