Description

Technical Field

[0001] The invention belongs to the technical field of fire fighting, and in particular to a fire fighting water gun head pressure testing device. Background Art

[0002] A fire hose is a water-shooting tool used for high-pressure firefighting. In order to extinguish fires, the water sprayed by the fire hose is dense and large in volume, and in order to be used as far away from the fire as possible, the range is increased by pressurizing.

[0003] The patent number is 201521023541.2, and the disclosure date is June 8, 2016. In a public specification, a fire hose pressure seal detection device is disclosed. The fire hose pressure seal detection device is equipped with a plug and a piston, which can block the outlet of the hose from the inside of the hose, so that the air can be discharged smoothly from the gap between the plug and the hose and the gap between the piston and the plug during the test, so as not to affect the pressure and sealing test results. The piston is arranged in the plug, and can fix itself and the plug to the outside of the through hole through a sleeve rod to prevent the piston from separating and falling off from the plug during the test.

[0004] The fire hose consists of a gun head body and a connection structure between the gun head and the fire hydrant. Since the high-pressure water flow from the gun head is sprayed out from the fire hydrant, the structural pressure resistance and sealing of these two parts need to be tested. In the existing technology, most of them can only test a part of the structure, and the safety performance cannot be guaranteed. Summary of the invention

[0005] The present invention aims to provide a fire hose head pressure testing device with more complete detection effect.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a fire hose head pressure testing device, including a workbench, the pressure testing device includes a support tube arranged on the workbench and a sleeve arranged on the support tube, the gun head is sleeved on the sleeve, and a sealing member is provided on the gun head.

[0007] The sleeve is provided with a water outlet, the support pipe is provided with a water pipe, and the support pipe is connected with the water outlet.

[0008] The gun head is divided into a head and a connecting ring, the sleeve seat is divided into a vertical seat and a horizontal seat, the head is sleeved on the vertical seat, the connecting ring is sleeved on the horizontal seat, and the sealing component includes a sealing plug and a sealing head.

[0009] The sealing plug is plugged in the head.

[0010] The vertical seat surface is provided with threads matching with the head.

[0011] The horizontal seat is provided with a threaded sleeve matched with the connecting ring.

[0012] The sealing head is mounted on the end of the connecting ring.

[0013] The technical effect of the present invention is: by dividing the gun head into two parts to test the sealing performance separately, the gun head is installed on the sleeve, and after plugging the mouth of the gun head, water is passed into the inside, and the sealing performance and pressure resistance of the fire hose head are tested by pressurized water flushing.
