Problems solved by technology
[0002] During firefighting work, sprinklers are usually used to form water mist to extinguish fires. Existing sprinklers generally have the problem of excessive water flow and small coverage, which is likely to cause waste of water resources. Insufficient atomization will damage electrical equipment, etc. Secondary damage to protected objects
In addition, there are vane nozzles and double-flow nozzles. Among them, the energy loss of the blade-type nozzles is relatively large, and the loss of compressed gas is too large for the double-flow nozzles, resulting in limited continuous fire extinguishing time.
[0003] In addition to their respective shortcomings, the above nozzles all have a common problem. Facing the same nozzle, the degree of atomization cannot be adjusted, and it cannot be widely used in various places for fire extinguishing

Embodiment 1
[0034] as attached figure 1 ~ attached Image 6 As shown, a blade-adjustable atomizing nozzle includes a nozzle housing, a water inlet, a swirl chamber 3 and a water outlet are arranged in the nozzle housing, and the water inlet is connected to the swirl chamber 3; the swirl chamber 3 is provided with Isolator 9;
[0035] A plurality of twisted blades 1 are arranged in the swirl chamber 3, and the water inlet of the twisted blades 1 is 15mm away from the water inlet of the nozzle. A twisted blade 1 is fixedly provided with a central rotating shaft 2, and one end of the central rotating shaft 2 is inserted into the isolation body 9, and the other end It passes through the nozzle housing and is connected with an adjustment mechanism.
[0036] The swirl chamber 3 is provided with a twisted vane 1. After the fluid passes through the swirl chamber 3, it forms a high-speed swirl flow, and is atomized at the outlet end due to the centrifugal force to form a spray to expand the spra...

The invention provides a blade-adjustable atomizing nozzle. The blade-adjustable atomizing nozzle comprises a nozzle shell; a water inlet, a rotational flow cavity and a water outlet are formed in the nozzle shell; the water inlet communicates with the rotational flow cavity; an isolator is arranged in the rotational flow cavity; a plurality of twisted blades are arranged in the rotational flow cavity; one twisted blade is fixedly provided with a central rotating shaft; one end of the central rotating shaft is inserted into the isolator; and the other end of the central rotating shaft penetrates through the nozzle shell and is connected with an adjusting mechanism. According to the blade-adjustable atomizing nozzle, the atomizing degree of the nozzle can be adjusted.
Description
technical field [0001] The invention relates to the technical field of fire sprinklers, in particular to an atomizing sprinkler with adjustable blades. Background technique [0002] During firefighting work, sprinklers are usually used to form water mist to extinguish fires. Existing sprinklers generally have the problem of excessive water flow and small coverage, which is likely to cause waste of water resources. Insufficient atomization will damage electrical equipment, etc. Damaged by the protected object twice. In addition, there are vane nozzles and double-flow nozzles. Among them, the energy loss of the water flow of the blade nozzle is relatively large, and the loss of compressed gas to the double-flow nozzle is too large, resulting in limited continuous fire extinguishing time. [0003] In addition to their respective shortcomings, the above-mentioned nozzles all have a common problem. In the face of the same nozzle, the degree of atomization cannot be adjusted, and...
