Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a high-pressure fine water mist open type sprinkler which is easy to clean and maintain. Background Art

[0002] The fine water mist fire extinguishing system can control, suppress and extinguish fires under the triple effects of cooling, suffocating and isolating thermal radiation. It has obvious advantages over traditional halogenated fire extinguishers. Therefore, it has received widespread attention in the industry. The high-pressure fine water mist open nozzle is an important component in the fine water mist fire extinguishing system. During use, there may be a certain amount of fine particles in the water quality, and long-term accumulation may form large particles of debris, while the water mist particles sprayed by the nozzle are relatively small. Therefore, the diameter of the spray hole on the nozzle is also very small, which is easily blocked by particles in the water quality, resulting in the inability of the fine water mist to be sprayed from the nozzle, affecting the fire extinguishing effect. In addition, the fine water mist open nozzle in the prior art is not easy to disassemble, and it is not convenient to clean the inside of the nozzle, resulting in high maintenance costs. Summary of the invention

DETAILED DESCRIPTION

[0012] like Figure 1 As shown, a high-pressure fine water mist open nozzle which is easy to clean and maintain includes a nozzle body 1, and the nozzle body 1 includes a first connecting part 2 and a second connecting part 3. The first connecting part 2 is provided with a first flow channel 4 for fluid to flow in, and the second connecting part 3 is provided with a second flow channel 5 and a plurality of nozzles 6 connected to the second connecting part 3. The first flow channel 4 and the second flow channel 5 are communicated, and the first connecting part 2 and the second connecting part 3 are threadedly connected by fixing bolts 7. The first connecting part 2 is provided with a first limiting groove 8, and the second connecting part 3 is provided with a second limiting groove 9. A filter element is provided at the connection between the first connecting part 2 and the second connecting part 3. When the first connecting part 2 and the second connecting part 3 are installed together, the shape enclosed by the first limiting groove 8 and the second limiting groove 9 is adapted to the shape and size of the filter element.

[0013] When the nozzle needs to be cleaned and maintained, it is only necessary to remove the fixing bolts 7, then take out the filter element, and clean the filter element. During the use of the nozzle, water will flow in from the first flow channel 4. In the process of water flowing to the second flow channel 5, it will be filtered through the filter element to filter out impurities in the water, thereby reducing large particles that flow into the second flow channel 5 with the water flow and enter the nozzle 6, thereby preventing the nozzle 6 from being blocked. This can greatly reduce maintenance costs. In addition, since the shape enclosed by the first limiting groove 8 and the second limiting groove 9 is compatible with the shape and size of the filter element, it can limit the filter element and ensure the stable position of the filter element.

[0014] The first connection part 2 is provided with a sealing gasket 10, and the second connection part 3 is provided with a positioning groove 11. The positioning groove 11 is adapted to the shape and size of the sealing gasket 10. When the first connection part 2 and the second connection part 3 are installed together, the positioning groove 11 corresponds to the position of the sealing gasket 10.

[0015] Since a sealing gasket 10 is provided on the first connecting part 2 and a positioning groove 11 is provided on the second connecting part 3, when the first connecting part 2 and the second connecting part 3 are installed together, the positioning groove 11 corresponds to the position of the sealing gasket 10, and the sealing gasket 10 can improve the sealing performance of the nozzle 6 and improve the fire extinguishing effect of the equipment.

[0016] The first connection part 2 is provided with a plurality of first positioning holes 12, the second connection part 3 is provided with a plurality of second positioning holes 13, and the filter element is provided with a plurality of third positioning holes 14. When the first connection part 2, the second connection part 3 and the filter element are assembled together, the positions of the first positioning holes 12, the second positioning holes 13 and the third positioning holes 14 correspond to each other, and the first positioning holes 12 and the second positioning holes 13 are threadedly connected by positioning bolts 15, and the positioning bolts 15 are respectively adapted to the shapes and sizes of the first positioning holes 12, the second positioning holes 13 and the third positioning holes 14.

[0017] When the first connecting part 2 and the second connecting part 3 are installed together, the positioning bolts 15 are respectively installed into the first positioning hole 12, the second positioning hole 13 and the third positioning hole 14, which can further improve the position stability of the filter element, thereby improving the filtering effect of the nozzle on impurities in the water.

[0018] A first gasket 16 and a second gasket 17 are respectively disposed on the first connection part 2 and the second connection part 3. When the first connection part 2 and the second connection part 3 are connected together, the first gasket 16 and the second gasket 17 are in contact with the filter elements respectively.

[0019] Because when the first connecting part 2 and the second connecting part 3 are connected together, the first gasket 16 and the second gasket 17 are in contact with the filter element respectively, the first gasket 16 and the second gasket 17 can press the filter element to improve the position stability of the filter element and avoid the position displacement of the filter element after being impacted by high-pressure water flow, thereby improving the filtering effect of the nozzle on impurities in the water.
