Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of fire fighting, specifically, the utility model relates to a fire water gun head pressure testing device. BACKGROUND

[0002] The fire water gun is a water jetting tool for high-pressure fire extinguishing. Since the fire water gun is used for fire extinguishing, the water jetting is dense and large in quantity, and the pressure is increased to improve the jetting range.

[0003] A pressure sealing detection equipment for a fire water gun is disclosed in a public specification with the patent number 201521023541.2 and the publication date of June 8, 2016. The pressure sealing detection equipment for the fire water gun is equipped with a plug and a piston. The outlet of the water gun can be plugged from the inside of the water gun. The air can be smoothly discharged from the gap between the plug and the water gun and the gap between the piston and the plug during detection, so as not to affect the detection results of the pressure and the sealing performance. The piston is arranged in the plug and can be fixed to the outside of the through hole by the sleeve rod, so as to avoid separation and falling of the piston and the plug during detection.

[0004] The fire water gun is composed of a gun head body and a connecting structure at the connection between the gun head and the fire hydrant. Since the high-pressure water flow is jetted from the fire hydrant, the structural pressure resistance and the sealing performance of the two parts need to be detected. In the prior art, only one part of the structure can be detected, and the safety performance cannot be guaranteed. UTILITY MODEL CONTENTS
