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] Append figure 1 Addition Image 6 As shown, a blade can be adjusted atomized nozzle, including a spray head housing, an inlet, a swirling chamber 3, and a water outlet, inlet and a swirl cavity 3, and in the swirl cavity 3 Isolation 9;

[0035] A plurality of twisted blades 1 are provided in the swirl chamber 3, and the twisted blades 1 feed edges are 15 mm from the air inlet inlet, and the twisting blade 1 is fixedly disposed, and the center rotation shaft 2 is inserted, the center rotation shaft 2 is inserted into the separator 9, the other end Pass through the spray head housing and the adjustment mechanism is connected.

[0036] The swirl chassis 1 is provided in the swirl chamber 3, and the fluid is formed to form a high speed swirl after the fluid passes through the swirling chamber 3, and since the action of the centrifugal force is atomized, the spray enlarged injection range is formed, and the twist blade 1 provides fluid to the fluid provides rotational performance...

Abstract

The invention provides an atomizing spray head with adjustable blades, which includes a spray head housing, a water inlet, a swirl chamber and a water outlet are arranged in the nozzle housing, and the water inlet is connected to the swirl chamber; an isolator is arranged in the swirl chamber A plurality of twisted blades are arranged in the swirl cavity, and a twisted blade is fixedly provided with a central rotating shaft, one end of which is inserted into the isolation body, and the other end passes through the nozzle housing and is connected with an adjustment mechanism. The blade-adjustable atomizing nozzle of the present invention can adjust the atomization degree of the nozzle.

Description

Technical field [0001] The present invention relates to the field of fire sprinklers, in particular, relating to a blade adjustable atomizing nozzle. Background technique [0002] When the fire is working, the water spray head is used to form a water fog for fire extinguishing. The existing water spray head is generally excessive water flow, less coverage, which is easy to cause waste of water, and the degree of atomization is not enough to apply electrical equipment. The protected object was destroyed twice. In addition, there is a blade nozzle and a dual flow nozzle, wherein the water flow energy loss of the blade spray head is too large, and the amount of loss of the two-flow nozzle to the compressed gas is too large, resulting in limited sustained fire extinguishing time. [0003] In addition to their own disadvantages, the spray head has a common problem, facing the same nozzle, and the degree of atomization is not adjustable, and it is not widely used for extinguishing of v...
