Description
Technical field
The present invention relates to a kind of extinguishing chemical shower nozzle of gas extinguishing system.
Background technology
Gas extinguishing system comprises storage bottle group, high-pressure hose, header, is arranged in a plurality of extinguishing chemical shower nozzles and self-extinguishing controller in the protection zone; the extinguishing mechanism of gas extinguishing agent is divided into two kinds of chemical action and physical actions; chemical action is the living radical in the inertia flame, the chemical reaction of inhibition burning; interrupt the chain reaction of burning, the intensity of a fire is put out rapidly.Physical action is to reduce the concentration of oxygen in the smelting zone, oxygen concentration is lower than keeps the required minimum of melting, and the intensity of a fire is because of losing the support fire smothering of enough oxygen.The extinguishing chemical nozzle layout of sprinkler of gas extinguishing system on the fixing body of the protection zone of gas extinguishing system since extinguishing chemical through shower nozzle to the protection zone ejecting extinguishing, its flow velocity, flow and condensation rate are key factors, the effect of directly influence putting out a fire.The structure of each shower nozzle that present gas extinguishing system is arranged in the protection zone usually as shown in Figure 3; it is formed by the nut segment 6 of upper end with the cylindrical section 7 that nut segment 6 forms one; shower nozzle is processed with cavity 12, and the cylindrical section sidewall is processed with a plurality of uniform spray orifices 10.The Chinese patent publication number is that the name of CN2406694 is called the patent of invention of " Gas nozzle of extinguisher ", a kind of Gas nozzle of extinguisher is disclosed, its arrival end is a screw socket, connect with the fire extinguishing pipe network by screw socket, its bottom has spray orifice, and the end face of described bottom can be a hemispherical, and its spray orifice is distributed on the hemisphere face, end face also can be columniform, and its spray orifice is distributed in reaching on the bottom surface of the face of cylinder all around.When installing, the extinguishing chemical shower nozzle of the gas extinguishing system of prior art needs on the fixing body of protection zone, to have the hole that header passes; the diameter of hole is greater than the maximum gauge of shower nozzle; therefore good looking appearance being installed is affected; a small amount of extinguishing chemical can splash to fixing body hole, protection zone; influence fire extinguishing effect; simultaneously the structure of the extinguishing chemical shower nozzle of the gas extinguishing system of prior art is also very unreasonable, and the flow velocity of extinguishing chemical, the adjustable range of flow are little, and the extinguishing chemical atomizing effect is relatively poor.
Summary of the invention
Technical problem to be solved by this invention is: the extinguishing chemical shower nozzle that a kind of gas extinguishing system is provided, the shower nozzle of this gas extinguishing system not only can make the installation profile more attractive in appearance, and the flow of extinguishing chemical, the adjustable extent of flow velocity are increased, thus improve the extinguishing chemical condensation rate, strengthen the fire extinguishing effect.
Solve this technical problem, technical scheme of the present invention is: a kind of extinguishing chemical shower nozzle of gas extinguishing system, it is by nozzle body, hold-down ring and protection atomized cover are formed, the protection atomized cover is made up of the curved body that torus and torus edge extend, the outer surface of described nozzle body is by the nut segment of diameter maximum, the frustum of a cone and be positioned at nut segment, cylindrical section between the frustum of a cone is formed, the cylindrical section of nozzle body has the external screw thread that matches with hold-down ring near nut segment, nozzle body has the shower nozzle cavity, the cylindrical section of nozzle body is provided with spray orifice uniform more than three, the sidewall of the frustum of a cone is provided with oblique spray orifice uniform more than four, and the top that described shower nozzle cavity is positioned at spray orifice is provided with the internal thread that cooperates with header.
The diameter of described protection atomized cover adopts 120～240 millimeters.
The diameter of described protection atomized cover is 180 millimeters.
The nozzle hole number of this cylindrical section of 1 of described nozzle is four, and the oblique nozzle hole number of the frustum of a cone sidewall of described nozzle body is six.
When gas extinguishing system is equipped with the extinguishing chemical shower nozzle of gas extinguishing system of the present invention on the fixing body of protection zone, the adjustable extent of extinguishing chemical flow, flow velocity is increased; Make the installation profile more attractive in appearance, improved the extinguishing chemical condensation rate, strengthened the fire extinguishing effect.

The specific embodiment
As shown in Figure 1 and Figure 2; a kind of extinguishing chemical shower nozzle of gas extinguishing system is made up of nozzle body 1, hold-down ring 2 and protection atomized cover 3; the similar pan that has the left-hand thread of circular hole of profile of protection atomized cover 3; it is made up of the curved body that torus and torus edge extend; the diameter of protection atomized cover 3 can adopt 120～240 millimeters; when diameter is 180 millimeters; the visual effect of shower nozzle that many gas extinguishing systems are housed on the protection zone fixing body 4 is better; and condensation rate the best, the fire extinguishing better effects if.
When gas extinguishing system is equipped with the extinguishing chemical shower nozzle of gas extinguishing system of the present invention on protection zone fixing body 4, can reduce the impulsive force of header 4 extinguishing chemicals ejection during use because of the frustum of a cone of nozzle body 1, increased the surface area that impacts, therefore compared with prior art, the adjustable extent of extinguishing chemical flow, flow velocity is increased; The protection atomized cover not only can be covered the hole of opening on the protection zone fixing body 4, makes the installation profile more attractive in appearance, and avoids extinguishing chemical to splash to protection zone fixing body 4 holes in use, has improved the extinguishing chemical condensation rate, has strengthened the fire extinguishing effect.
