Description
Technical field
The utility model relates to the fire-fighting fire extinguishing field, is specifically related to a kind of antidrip super fine mist spraying head.
Background technology
Along with people's is to the further investigation of fire extinguishing system, and fine water mist fire-extinguishing system has progressively substituted Kazakhstan alkyl halide and water sprinkling fire-distinguishing system, and is used widely by people institute, but also there is its limitation in fine mist fire-fighting.Fine water mist fire-extinguishing system is in the moment of closing, and the pressure of pipeline inner high voltage water sharply reduces, and remaining water can flow out the generation weeping through fine mist spray head in the pipeline.
Summary of the invention
The purpose of the utility model is to provide a kind of antidrip super fine mist spraying head, can prevent that water remaining in the pipeline is through the shower nozzle water clock in the moment that fine water mist fire-extinguishing system is closed.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved.
A kind of antidrip super fine mist spraying head is characterized in that, comprises sprayer body, axially is connected the upper connector and the lower connector of sprayer body; Be provided with the branch water cavity in the said sprayer body, divide water cavity to be communicated with and be arranged on the nozzle on the sprayer body; Said lower connector axially is provided with the intake tunnel that is communicated with said minute water cavity, axially is provided with the valve support in the said upper connector, and sliding on the valve support is penetrated with valve rod, and the valve rod bottom is provided with the spool that is sealed and matched with said intake tunnel; Be set with helical spring on the said valve rod, helical spring is between spool and valve support.
The characteristics of the antidrip super fine mist spraying head of the utility model are with further improving:
Said upper connector is provided with nozzle, and said nozzle is positioned at valve support top.
The outlet of the intake tunnel of said lower connector is the conical surface that cooperates with seal spool.
The root of said spool is set with the O RunddichtringO.
Said upper connector and lower connector are respectively through the sprayer body that is threaded.
The inlet of the intake tunnel of said lower connector is provided with filter screen.
In the utility model, upper connector, sprayer body and lower connector axially are connected successively, are provided with the branch water cavity in the sprayer body, divide water cavity to be communicated with and are arranged on the nozzle on the sprayer body; Said lower connector axially is provided with the intake tunnel that is communicated with said minute water cavity, axially is provided with the valve support in the said upper connector, and sliding on the valve support is penetrated with valve rod, and the valve rod bottom is provided with the spool that is sealed and matched with said intake tunnel; Be set with helical spring on the said valve rod, helical spring is between spool and valve support.Like this, utilize helical spring elastic force to realize being sealed and matched of spool and intake tunnel, when opening fine water mist fire-extinguishing system, under the effect of powerful hydraulic pressure, the spool compression helical spring, spool is opened, the shower nozzle water spray; When closing fine water mist fire-extinguishing system, hydraulic pressure sharply descends, and helical spring recovers, and spool and intake tunnel are sealed and matched, thereby block the water source, prevent the shower nozzle water clock.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
Fig. 1 is the cross-sectional schematic of a kind of antidrip super fine mist spraying head of the utility model;
Fig. 2 is the schematic top plan view of Fig. 1;
Among the figure: 1, top connection; 2, nozzle; 3, sprayer body; 4, lower connector; 5, filter screen; 6, valve support; 7, valve rod; 8, helical spring; 9, divide water cavity; 10, O RunddichtringO; 11, spool; 12, intake tunnel.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of antidrip super fine mist spraying head for the utility model mainly comprises sprayer body 4, axially is connected the upper connector 1 and lower connector 4 of sprayer body 3.Upper connector 1 and lower connector 4 are respectively through the sprayer body 3 that is threaded, and the O RunddichtringO is adopted in sealing each other.
Be provided with branch water cavity 9 in the sprayer body, divide water cavity 9 to be communicated with and be arranged on the nozzle 2 on the sprayer body 3.In the present embodiment, the nozzle 2 on the sprayer body 3 is six that circumferentially are uniformly distributed with, and the axis angle of nozzle 2 directions and sprayer body 3 is 45 °.
Axially be provided with the intake tunnel 12 that is communicated with branch water cavity 9 at lower connector 4, in upper connector 1, axially be provided with valve support 6, sliding on the valve support 6 is penetrated with valve rod 7, and valve rod 7 bottoms are provided with the spool 11 that is sealed and matched with intake tunnel 12; In addition, the conical surface of the outlet of the intake tunnel 12 of lower connector 4 for being sealed and matched with spool 11, the root of spool 11 is set with O RunddichtringO 10, so that being sealed and matched of the outlet of intake tunnel 12 and spool 11.Upper connector 1 is provided with nozzle, and this nozzle is positioned at valve support 6 tops, the dead in line of nozzle direction and upper connector 1.
On valve rod 7, be set with helical spring 8, helical spring 8 is between spool 7 and valve support 6.When opening fine water mist fire-extinguishing system, under the effect of powerful hydraulic pressure, spool 7 compression helical springs 8, spool 7 is opened, nozzle 2 water sprays; When closing fine water mist fire-extinguishing system, hydraulic pressure sharply descends, and helical spring 8 recovers, and spool 11 is sealed and matched with intake tunnel 12, thereby blocks the water source, prevents shower nozzle 2 water clocks.In addition, the inlet of the intake tunnel 12 of lower connector 4 is provided with filter screen 5, can further filter press water, reduces the obstruction probability of nozzle 2.
Although more than combine accompanying drawing that the embodiment of the utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
