Embodiment 1

[0019] The pipe seat (1) of the rotary sieve type large-flow fire extinguishing nozzle is connected with the system fire extinguishing pipeline, and an electromagnetic valve (9) is arranged on its upper end, and the electromagnetic valve (9) is opened by the control of the flame detector (10). Such as figure 1 , figure 2 As shown, the shunt (3) at the lower end of the tube base (1) is connected and fixed by the bracket (2), and the tip of the conical shunt (3) is facing the center of the lower end of the tube base (1). ) is equipped with a circular water divider (6) below, which is evenly distributed with a plurality of bar-shaped sieves (8) radiating outwards with the axis, and two vortex blades ( 7), this water dividing wheel (6) forms a revolving pair by the bearing axle seat (4) and the pipe seat (1), and the inside is equipped with a bearing.

Embodiment 2

[0021] Such as image 3 , Figure 4 As shown, embodiment 2 is substantially the same as embodiment 1, except that the shape and structure of the two vortex blades are changed, which can change the spray radius during fire extinguishing.

[0022] When the large flow fire extinguishing nozzle is installed in the fire extinguishing system engineering, if Figure 5 As shown, the large space place of this project is 30 meters high, and the sprinklers (11), (12), (13), (14) are vertically installed on the top of the indoor ceiling, occupying a high position downwards, and form a group. A solenoid valve (9) is installed at the front end, and they are controlled by a flame detector (10) and can be opened simultaneously; 15) is connected, and the flame detector (10) is connected with the electric valve (9) of the bus control cabinet (16). (above-mentioned sprinkler head (11), (12), (13), (14) are all DN50).

Abstract

The invention provides a rotary screen type big-flow fire extinguishing sprayer, which comprises a tube socket, a support bracket, a flow divider, a shaft bearing water dividing wheel, and vortex current blades, the upper tube socket is connected and fixed with the fire extinction water supply pipe, the lower portion is in running fit with the shaft bearing, the water dividing wheel is provided with a cone shaped flow divider over the center and is mounted and fixed with the support bracket, the water dividing wheel is provided with a plurality of bar-shaped sieving ports radially outwards from the axes. The sprayer can be in combination control with high altitude flame detector and solenoid valve, which solves the problem of small radius of fire extinction sprayer sprinkling and delayed unlatching.

Description

technical field [0001] The invention relates to a fire extinguishing device accessory for fire fighting, in particular to a rotary sieve type large flow fire extinguishing nozzle device used in a structure, which is suitable for being installed in a structure with a large space and used as a fire sprinkler for fire extinguishing . Background technique [0002] The fire extinguishing nozzles being used in the market now include old-fashioned temperature-sensitive closed nozzles and open centrifugal nozzles. The temperature-sensitive closed nozzle uses a glass bubble of 68 degrees to absorb the temperature of the fire combustion airflow, so that when the liquid in the bubble expands to a critical point, it begins to explode and open the valve plug to spray water to extinguish the fire. Its disadvantage is that the bubble explosion time lags behind obviously. Fire; the Achilles’ heel of the open centrifugal sprinkler head is that the torque of the two side thrust nozzles of th...
