Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure fine water mist guns, in particular to a rotary switching double-channel high-pressure fine water mist gun. Background Art

[0002] A high-pressure fine water mist gun is a new type of professionally designed fire-fighting equipment. During the working process of the high-pressure fine water mist gun, a high-pressure pump sends water into the spray gun system. After passing through channel selection and switching, the high-pressure water becomes tiny water droplets through the refinement effect of the corresponding nozzle. Due to the kinetic energy provided by the high-pressure pump and the design of the nozzle, the water droplets can form a uniform mist and are sprayed into the air through the nozzle outlet.

[0003] Although the existing high-pressure fine water mist guns can form fine water mist particles, there are certain limitations in their appearance, structure and functions. Moreover, there are basically some problems in the actual use of the existing high-pressure fine water mist guns, such as structural rationality, functional reliability and service life.

On one side of the rotary block B, a spray head valve core, a tetrafluoroethylene sealing gasket, a sixth sealing ring, a rubber sleeve and a steel ball are arranged.

[0007] On the upper part of one side of the spray head valve core, a plug, a copper ring tightening nut are connected, and on the lower part of one side of the spray head valve core, two double pipe joints, a first sealing ring and a first screw are connected.

[0008] In addition, the preferred structure is that on one side of the double pipe joint, a fixing block, an end sleeve, a second screw, a second sealing ring, a first round pipe and a second round pipe are connected.

[0011] In addition, the preferred structure is that on one side of the valve core, a fourth sealing ring, an inner sleeve pipe, a fifth sealing ring, a spray head and a flat spray head are arranged.

[0012] In addition, a preferred structure is that a fog nozzle seat, a lower nozzle, and an upper nozzle are arranged on one side of the valve core.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model, high-pressure water flow passes through the rotating block B and the rotating block A from the spray gun handle, and the rotating block A rotates through the rotating gun body to complete the flow channel switching; the water flow sequentially passes through the first circular tube, the valve core, the lower nozzle, and the upper nozzle to form a narrow-angle long-range spraying posture at the center; the water flow sequentially passes through the second circular tube, the valve core, the fog nozzle seat, the fog flat nozzle, and the 6 fog flat nozzles around the nozzle to form a wide-angle short-range spraying posture.

On one side of the rotary block B 38, there are arranged a spray head valve core 6, a tetrafluoro sealing gasket 34, a sixth sealing ring 39, a rubber sleeve 33, and a steel ball 28;

[0021] On the upper part of one side of the spray head valve core 6, there are connected a plug 31, a copper ring 7, and a tightening nut 8. And on the lower part of one side of the spray head valve core 6, there are connected two double-tube connectors 5, a first sealing ring 20, and a first screw 25.

[0022] And, on one side of the double-tube connector 5, there are connected a fixing block 9, an end sleeve 13, a second screw 32, a second sealing ring 21, a first round tube 10, and a second round tube 11.

[0023] And, outside the two double-tube connectors 5, there is arranged a front-end sleeve 17. And outside the double-tube connectors 5, there are arranged a valve core 4, an outer sleeve tube 2, and a third sealing ring 22.
