The specific embodiment
As shown in Figures 1 to 4, the fine mist spray head of this straight atomization nozzle and vortex atomizing nozzle combination, comprise a head body 1 and be arranged on 5 vortex atomizing nozzles 2 in this head body 1 by thread seal, there is a pipelined channel 3 this head body 1 inside, in this head body 1, also by thread seal, a straight atomization nozzle 4 is installed, this vortex atomizing nozzle 2 is evenly arranged centered by this straight atomization nozzle 4.This vortex atomizing nozzle 2 comprises a cavity 6 and an atomization core 7 being arranged in this cavity 6, and this cavity 6 comprises a water inlet and an apopore, and the water inlet of this vortex atomizing nozzle 2 is connected with this pipelined channel 3.This atomization core 7 is evenly provided with 3 cylindrical conveyor screws of spiral fluted for outside, and this spiral fluted internal diameter dwindles from the inlet to the outlet gradually, and this atomization core 7 can make water under high pressure form thin water smoke at apopore.Head body 1 water inlet adopts internal thread to connect.
The cavity of this straight atomization nozzle 4 for comprising a water inlet and 10 apopores 5, the water inlet of this straight atomization nozzle 4 is connected with this pipelined channel 3, the apopore 5 of this straight atomization nozzle 4 is evenly arranged with circumferencial direction, and the apopore 5 of this straight atomization nozzle 4 is the stepped hole that aperture expands gradually from inside to outside.
The leak-proof device that a sealing gasket 9 by intermediate openings, packed-piston 8, temperature sensing glass ball 10 form is set in the pipelined channel 3 of this head body 1, can in the time of non-fire extinguishing state, prevents that this fine mist spray head from leaking.The opening of the conical nose of sealing piston 8 and sealing pad 9 forms and is sealed and matched, sealing pad 9 forms and is sealed and matched with the inwall of this head body 1, temperature sensing glass ball 10 is inconsistent with the afterbody of sealing piston 8, and sealing piston 8 can be freely movable in this pipelined channel 3.There is a protrusion member in the central authorities of this straight atomization nozzle 4, and this temperature sensing glass ball 10 is arranged in this protrusion member.
Temperature sensing glass ball 10 fragmentations under high temperature of fire condition, packed-piston 8 moves to temperature sensing glass ball 10 directions under Water Pressure, water inlet water source enters head body inside, respectively from the apopore 5 high speed ejections of vortex atomizing nozzle 2 and straight atomization nozzle 4, interact and form thin water smoke with air again.
For guaranteeing that fine mist spray head has best atomizing effect, the ratio (being k-factor) of the straight flow of atomization nozzle and the flow of whole fine mist spray head need change with the change of distance of fine mist spray head and flame failure protection object, and distance is larger, and ratio is larger.The quantity of the apopore of straight atomization nozzle also needs to adjust accordingly, changes the straight atomization nozzle of individual features.
In the time that shower nozzle distance protection object exceedes 5 meters, the flow k-factor accounting of straight atomization nozzle is 70～80%, guarantees that the thin water smoke that shower nozzle produces has stronger penetration power; When shower nozzle guard space is less than the object of 5 meters, the flow k-factor of straight atomization nozzle accounts for 20～30% of whole capacity of sprinkler, guarantees that shower nozzle has best atomizing effect.
Other parts in fine mist spray head do not change, and temperature sensing glass ball can be replaced by spring.This fine mist spray head that possesses drip-proof function, when only having inlet water pressure to overcome acting force of the spring, shower nozzle just can be sprayed water and be formed thin water smoke.When hydraulic pressure is lower, shower nozzle is closed automatically, effectively avoids water clock and water column to spray.
It should be noted that; the specific embodiment is only explanation and the explanation to technical solutions of the utility model; should not be understood as the restriction to technical solutions of the utility model; any employing the utility model essence summary of the invention and only do local change, must fall in protection domain of the present utility model.
