3. Parameters of Chongqing high-pressure water mist closed sprinkler head

There are many parameters involved in Chongqing high-pressure water mist closed nozzles, the more important of which are working pressure, flow rate or flow coefficient, temperature and size of the glass ball, nozzle interface size, material, etc. These are what customers must provide when purchasing or customizing. Of course, if you want to produce a more suitable high-pressure water mist closed nozzle, the more specific parameters you provide, the higher the applicability of the produced nozzle will be. The performance parameters of Chongqing high-pressure water mist closed nozzles are as follows:

① Working pressure: The mist droplets formed by high-pressure fine water mist nozzles are finer than those of medium and low-pressure water mist, and the flow rate is smaller.

②Flow rate: refers to the total amount of mist particles ejected by the nozzle per unit time. The flow rate depends on the cross-sectional area of ​​the nozzle and the flow rate of the water.

③Particle size (droplet size) distribution: usually calculated using a function.

④Fog particle characteristic quantity: In practical applications, the volume average particle size is often used to measure the fog particle characteristic quantity.

⑤ Momentum of fog particles: It is determined by the diameter of fog particles. The amount of momentum determines the fire extinguishing performance.

⑥Spray angle: The size of the spray angle will affect the height and protection range of the nozzle we install. Nozzles with small spray angles are installed in places with high heights and concentrated combustion areas. The size of the spray angle is determined by the nozzle structure design.

⑦ Range: The range is directly related to the momentum of fog particles. The range determines the installation height of the nozzle.

⑧Protection diameter: refers to the diameter of the circle covered by mist droplets in a plane 1 meter away from the bottom of the nozzle.

4. Principle of Chongqing high-pressure water mist closed sprinkler head

Chongqing high-pressure water mist closed nozzle is composed of nozzle body, nozzle, nozzle core, glass ball and filter. After water under a certain pressure enters the nozzle through the nozzle filter, the pressure water is ejected from the nozzle hole at high speed, causing strong friction with the surrounding air. The water flow is torn, thus forming a fine water mist sprayed at a certain angle.

Working principle of closed wet system:

Under quasi-working conditions, the high-pressure water mist fire extinguishing system maintains a certain pressure from the outlet of the pump unit to the pipe network in front of the nozzle. When the temperature of the glass bubble of the closed nozzle reaches the operating temperature, the glass bubble breaks and the pipeline pressure drops. When the pressure is lower than the set starting pressure of the pressure-stabilizing pump, the pressure-stabilizing pump starts to maintain a stable pressure in the system pipe network. When the pressure-stabilizing pump runs for more than a certain period of time and the pipe network pressure is still not reached, the main pump starts and the pressure-stabilizing pump stops. The flow switch feeds back the spray signal of the system. After receiving the feedback signal, the host computer turns on the spray indicator light.

5. Chongqing high-pressure water mist closed sprinkler price

Reference price: 200~240 yuan/piece

The price of Chongqing high-pressure water mist closed sprinklers is more expensive than ordinary fire sprinklers. After all, its scope of application and fire-extinguishing effect are beyond the reach of ordinary sprinklers. Moreover, the structural design of high-pressure water mist closed nozzles is relatively complex. The market price of glass balls alone is as high as about one hundred yuan, so the price of high-pressure water mist closed nozzles is naturally not too low.
