Problems solved by technology

The speed of fine water mist formed by the straight spray nozzle is much higher than that of the swirl atomization nozzle, and the penetration and range are also much higher than that of the swirl atomization nozzle. Larger, not suitable for applications where the distance between the protective object and the nozzle is relatively close

Embodiment Construction

[0022] Such as Figure 1 to Figure 4 As shown, the fine water mist spray head of the combination of the straight spray nozzle and the swirl atomization nozzle includes a spray head body 1 and 5 swirl atomization nozzles 2 installed on the spray head body 1 by thread sealing, the spray head body 1 has a water flow channel 3 inside, and a straight spray nozzle 4 is installed on the spray head body 1 through thread sealing, and the swirl spray nozzle 2 is evenly arranged around the straight spray nozzle 4. The swirl atomizing nozzle 2 includes a cavity 6 and an atomizing core 7 arranged in the cavity 6, the cavity 6 includes a water inlet and a water outlet hole, the water inlet of the swirl atomizing nozzle 2 It communicates with the flow channel 3 . The atomizing core 7 is a cylindrical helix with three spiral grooves evenly arranged on the outside, the inner diameter of the spiral grooves gradually decreases from the entrance to the exit, and the atomizing core 7 can make the...

Abstract

The invention discloses a water mist nozzle with combination of direct-spray atomizing nozzle and cyclone atomizing nozzles. The water mist nozzle comprises a nozzle body (1) and a plurality of cyclone atomizing nozzles (2) arranged on the nozzle body (1), wherein a water channel (3) is formed in the nozzle body (1), and a direct-spray atomizing nozzle (4) is also arranged on the nozzle body (1); the direct-spray atomizing nozzle (4) is a cavity with one water inlet and more than one water outlet (5), and the water inlet of the direct-spray atomizing nozzle (4) is communicated with the water channel (3). The water mist nozzle with combination of direct-spray atomizing nozzle and cyclone atomizing nozzles not only has better atomizing effect, but also has stronger penetrating power and smaller atomizing distance, and can extinguish the fire far away from or close to the nozzle.

Description

technical field [0001] The invention relates to a fine water mist nozzle combined with a straight atomization nozzle and a swirl atomization nozzle, comprising a nozzle body and a plurality of swirl atomization nozzles arranged on the nozzle body, and a flow channel inside the nozzle body . Background technique [0002] The fine water mist nozzle is a device that can atomize the water flow into a particle size of less than 1mm (usually less than 0.4mm). The existing fine water mist nozzle mainly has two structures. One is a swirl atomizing nozzle, which includes a nozzle body and a plurality of swirl atomization nozzles arranged on the nozzle body. There is a water channel inside the nozzle body. As long as the water inlet provides a water source with a certain pressure, the nozzle will Multiple nozzles spray water for atomization. In order to atomize the water flow, the nozzle usually has a built-in atomizing core. The atomizing core is a part that can rotate the water fl...
