It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a fire testing device, including a test pipe 1, a connecting pipe 1 7, and a connecting pipe 2 8.

The outer walls of the valve core 11 and the valve core 2 12 are equipped with springs. The first sealing head 13 and the second sealing head 18 are tightly fitted with the corresponding conical openings by the action of the springs.

[0023] The specific settings and effects of the embodiment will be described below. When detecting the fire-fighting equipment, the second connecting pipe 8 is installed on the fire-fighting equipment, and the first connecting pipe 7 is installed on the water testing device. Since the first connecting pipe 7 and the second connecting pipe 8 are connected by buckling, the water testing device and the fire-fighting equipment can be freely connected and separated. When the water testing device and the fire-fighting equipment are not connected, the outer end of the valve core 12 is not subjected to pressure, and the valve core 12 and the plug head 13 are only subjected to the elastic force of the spring, so that the plug head 13 moves outward and is in contact with the tapered port of the second connecting pipe 8, thereby realizing the sealing of the water flow. In the separated state, the water flow in the fire-fighting equipment will not overflow, thereby avoiding the waste of water resources. When water testing is needed, the first connecting pipe 7 and the second connecting pipe 8 are connected to each other, and one end of the second connecting pipe 8 is inserted into the inner side wall of the first connecting pipe 7, so that the outer ends of the valve core 11 and the valve core 12 are connected to each other. The pressure generated by the contact between the valve core 11 and the valve core 12 is used to resist the elastic force of the two springs, so that the valve core 11 and the valve core 12 are separated from each other, the plug head 13 and the plug head 18 are separated from the two tapered ports respectively, and the water passages in the first connecting pipe 7 and the second connecting pipe 8 are connected, so that the water flow freely flows into the water testing pipe 1. Then, the water testing pipe 1 is used for water testing and detection. The pressure gauge 4 is used to detect whether the water pressure of the fire-fighting device meets the fire-fighting standard. The water nozzle 5 is used for water spraying test to detect whether the effective water spraying distance of the fire-fighting device meets the requirements.

[0026] The use method and working principle of the device are as follows: when the fire-fighting equipment is detected, the docking pipe one 7 is installed on the water testing device, the docking pipe two 8 is installed on the fire-fighting equipment, and the two are freely docked and separated through buckling. When not being docked, the valve core two 12 and the blocking head one 13 are pressed by the spring force, so that the blocking head one 13 is attached to the tapered port of the docking pipe two 8, and water overflow is prevented. When water testing, the docking pipe two 8 is inserted into the docking pipe one 7, the valve core one 11 and the valve core two 12 are contacted to generate pressure and are separated from each other, the blocking head one 13 and the blocking head two 18 are separated from the tapered port, the waterway is connected, the water flows into the water testing pipe 1, and the water pressure and the water spraying distance are detected through the pressure gauge 4 and the water spraying nozzle 5.
