Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the atomization groove 31 of the atomization core 3 in this embodiment is arc-shaped, and in the horizontal projection of the atomization groove 31, the arc of the atomization groove 31 is between 5°~15° , and the tangent of the starting point of the atomizing groove 31 on the arc deviates from the starting point to the radial line of the center of the top circle plane 32 by a certain angle β, and the range of β is between 0° and 10°. The rest of the settings in this embodiment are the same as in Embodiment 1.

[0032] In the above embodiments, due to the special structural arrangement of the atomizing core 3 and the nozzle 2, the closed medium-low pressure fine water mist spray head of the present invention can spray fine particles with uniform and dense droplets, small droplet diameter, large impulse and wide atomization angle. Water mist has ideal spray effect and good fire extinguishing effect. This...

Abstract

The invention relates to a closed middle and low pressure water mist sprayer, which comprises a hollow sprayer seat, a spray nozzle, an atomization core and a temperature sensing mechanism, wherein the spray nozzle is provided with a water outlet; the temperature sensing mechanism is capable of automatically starting water spray when temperature exceeds a critical point; a first cavity body is formed in the spray nozzle; the atomization core is arranged in the first cavity body of the spray nozzle; a second cavity body is formed in the atomization core; the side wall of the second cavity bodyis provided with a water flowing hole; the top part of the second cavity body is provided with a straight line-shaped or arc-shaped atomization slot; and the second cavity body, the water flowing hole, the atomization slot and the water outlet are communicated with each other. The closed middle and low pressure water mist sprayer is capable of spraying water mist with even and dense mist drops, asmall grain diameter, high momentum and a wide atomization angle, has an ideal mist spray effect and a good extinguishment effect and has a very important meaning and practical application value for markets of the closed middle and low pressure water mist sprayer which is difficult to obtain the ideal mist spray effect under a middle and low pressure water source at present.

Description

technical field [0001] The invention relates to a liquid atomizing nozzle in fire-fighting equipment, in particular to a closed medium-low pressure fine water mist nozzle. Background technique [0002] The water mist fire extinguishing system has the advantages of environmental protection, safety, strong fire extinguishing ability, less water consumption for fire extinguishing, less water pollution and wide application range. It is an environmentally friendly and efficient fire extinguishing technology and is widely used in the field of fire protection. The water mist nozzle is the key component of the water mist fire extinguishing system and the most important factor affecting the fire extinguishing performance of the fire extinguishing system. According to the different starting methods, the fine water mist nozzles can be divided into two types: open type and closed type. Among them, the closed type nozzles can sense the occurrence of fire and start to spray fire extinguis...
