Abstract
The utility model discloses a kind of shower nozzle for low pressure carbon dioxide fire extinguishing systems, comprise sprayer body, described sprayer body is provided with center and spurts hole, flow distribution plate is provided with below described sprayer body, described flow distribution plate is connected with sprayer body by joint pin, on described flow distribution plate, center spurts corresponding position, hole and is provided with shunting guide cone, and on described flow distribution plate, shunting guide cone surrounding is provided with multiple tap hole.The utility model adopts the nozzle structure of single hole sprayer body porous bypass type, shower nozzle adopts center monotrysian type structural drag loss less, the open space that sprayer body and flow distribution plate rely on joint pin to be connected to form in the process of spurting is larger, dry ice can not be formed pile up when carbon dioxide gasification, thus avoid the situation of the dry ice blocking that shower nozzle occurs, carbon dioxide is normally erupted, thus ensure that the safe and reliable work of system.
Description
Technical field
The utility model belongs to fire-fighting equipment technical field, particularly a kind of shower nozzle for low pressure carbon dioxide fire extinguishing systems.
Background technology
Present low pressure carbon dioxide fire extinguishing systems is divided into total flooding extinguishing system and local application extinguishing system.The low pressure carbon dioxide fire extinguishing systems of most producer all adopts the nozzle structure of four spray orifices 7, as shown in Figure 1.Due to the vertical direction that spray orifice direction flows at carbon dioxide, therefore four hole shower nozzle drag losseses are larger, therefore because continuous blowdown time is longer in local application extinguishing system, or in the total flooding extinguishing system that the short period repeatedly spurts, the carbon dioxide of gas-liquid two-phase gasifies through spray orifice, a large amount of heats can be absorbed, spray orifice is made to form carbon dioxide dry ice particle, when blowdown time is longer or the short period repeatedly spurts, carbon dioxide dry ice particle forms packing phenomenon at spray orifice, add that carbon dioxide continues to flow through herein, easily form the blocking of carbon dioxide dry ice at spray orifice, affect normally spurting of carbon dioxide, cause the disabler of low pressure carbon dioxide fire extinguishing systems.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, and dry ice blocks to provide one effectively to avoid shower nozzle to occur, thus ensures the shower nozzle for low pressure carbon dioxide fire extinguishing systems that carbon dioxide normally erupts.
The technical solution adopted in the utility model is such: a kind of shower nozzle for low pressure carbon dioxide fire extinguishing systems, comprise sprayer body, it is characterized in that: on described sprayer body, be provided with center spurt hole, flow distribution plate is provided with below described sprayer body, described flow distribution plate is connected with sprayer body by joint pin, on described flow distribution plate, center spurts corresponding position, hole and is provided with shunting guide cone, and on described flow distribution plate, shunting guide cone surrounding is provided with multiple tap hole.
Shower nozzle for low pressure carbon dioxide fire extinguishing systems described in the utility model, multiple tap hole described in it is distributed on same circumference to shunt to be centered by guide cone.
Shower nozzle for low pressure carbon dioxide fire extinguishing systems described in the utility model, the circumferential edges of tap hole described in it is tangent with shunting guide cone root position.
Shower nozzle for low pressure carbon dioxide fire extinguishing systems described in the utility model, it is bellmouth or straight hole that hole is spurted at center described in it.
The utility model adopts the nozzle structure of single hole sprayer body porous bypass type, shower nozzle adopts center monotrysian type structural drag loss less, the open space that sprayer body and flow distribution plate rely on joint pin to be connected to form in the process of spurting is larger, dry ice can not be formed pile up when carbon dioxide gasification, thus avoid the situation of the dry ice blocking that shower nozzle occurs, carbon dioxide is normally erupted, thus ensure that the safe and reliable work of system.

Mark in figure: 1 is sprayer body, and spurt hole centered by 2,3 is flow distribution plate, and 4 is joint pin, 5 is shunting guide cone, and 6 is tap hole, and 7 is spray orifice.
Detailed description of the invention
below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 3, shown in 4 and 5, a kind of shower nozzle for low pressure carbon dioxide fire extinguishing systems, comprise sprayer body 1, described sprayer body 1 is provided with center and spurts hole 2, hole 2 is spurted for bellmouth or straight hole in described center, flow distribution plate 3 is provided with below described sprayer body 1, described flow distribution plate 3 is connected with sprayer body 1 by joint pin 4, on described flow distribution plate 3, center is spurted corresponding position, hole 2 and is provided with shunting guide cone 5, on described flow distribution plate 3, shunting guide cone 5 surrounding is provided with four tap holes 6, described four tap holes 6 are distributed on same circumference to shunt to be centered by guide cone 5, the circumferential edges of described tap hole 6 is tangent with shunting guide cone 5 root position.
Wherein, described shower nozzle entirety adopts copper alloy or stainless steel casting.
Carbon dioxide spurts hole by center and spurts, what utilize shunting guide cone, flow distribution plate diffusion carbon dioxide spurts angle, flow distribution plate shield portions, by tap hole shunt carbon dioxide spurt flow, make the uniform flow spurting the carbon dioxide in angle of whole carbon dioxide, thus ensure that the extinguishing effect spurting carbon dioxide.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
