Description
Technical Field
The invention relates to the technical field of fire fighting, in particular to a fire fighting water pressure loop control valve of a high-rise building and an indoor fire fighting device formed by the fire fighting water pressure loop control valve.
Background
With the increasing population density of modern cities, residential buildings, office buildings and shopping malls are developed to high-rise buildings and super high-rise buildings, which is the development trend of modern cities, and the high-rise buildings have the advantages of small occupied land, large population accommodation and the like. Meanwhile, fire protection of high-rise buildings faces a severe test, wherein the biggest disaster threatens and the most common is fire. The high-rise building which often accords with the existing fire-fighting design specification does not play a role in time and effectively when a fire disaster happens, so that major casualties and accidents with great loss of lives and properties are caused, and the reasons are mainly as follows:
1. high-rise and super high-rise building personnel are more, once a fire alarm sounds, people in a building are firstly evacuated, and the evacuation of people takes a long time and the corridor is crowded at the moment.
2. The existing fire-fighting facilities comprise a fire-fighting spray system and a fire hydrant, and the spray system only works under the conditions of small fire intensity and right fire point position; if the fire hydrant needs to be trained to be used, people only need to escape first when a fire disaster happens, and no one uses the fire hydrant to extinguish the fire; professional firefighters are often on the way to the fire scene at this time.
3. The high-rise and super high-rise buildings are designed to have a plurality of vertical pipe wells and other parts, so that once a fire disaster occurs, a chimney effect is easily generated to form three-dimensional combustion, the fire spread is very fast, the floor height is high, more people exist, the building layout is complex, and serious casualties are easily caused.
If a fire occurs in a high-rise or super high-rise building, the fire intensity is too large to be controlled when a fire brigade arrives at the fire scene, and although the existing fire fighting equipment is very advanced, the fire fighting equipment for the high-rise or super high-rise building in most cities is very few and is very time-consuming and difficult to mobilize. At the moment, people are still evacuated, and the firefighters can hardly go upstairs and cannot be allowed to go upstairs to extinguish the fire due to the spread of the fire, so that great loss is caused. Therefore, a fire fighting device which can be effectively and conveniently operated by common people is urgently needed for high-rise and super high-rise buildings to deal with high-rise fire, a spraying system can be started when the fire happens, time is strived for evacuation of people, an indoor fire fighting device is arranged, and casualties are reduced.

The invisible fixed fire-fighting lance 7 is provided with a fixing device 73, and the invisible fixed fire-fighting lance 7 is connected and fixed with the water pressure piston pusher 1 through the fixing device 73. The specific implementation mode is as follows: the invention needs to be matched with a water pressure loop system for use, and the water pressure loop system comprises a reservoir arranged at the top of a building and an electric control/manual integrated water valve arranged in a fire control chamber and is connected with a water pressure loop control valve through a unit valve opening pressure pipe 9. The water pressure loop control valve is matched with the sealed fire water valve 2 through the water pressure piston pusher 1, so that the water pressure loop control valve can be controlled in two ways; firstly, the U-shaped bolt 5 is pulled out from the invisible fire hydrant at the position where fire is started, the top rod 3 of the fire-fighting water valve is bounced upwards under the action of pipeline pressure to form a passage, and water flows out to extinguish the fire; its two-way is controlled through the fire control room, through the automatically controlled/manual integrative water valve of corresponding floor and unit in the fire control room, open the water valve, will have rivers to pass through in the unit valve opening pressure pipe 9, the piston valve of water pressure piston impeller 1 will be under the effect of water pressure, pop out U type bolt 5 through two thimbles that set up on it, fire control water valve ejector pin 3 will upwards bounce under the effect of pipeline pressure, will form the route, rivers will flow out and put out a fire. Through above two kinds of modes, make fire control can realize scene and remote control dual mode, can be with the intensity of a fire separation in one side of door or window, prevent that the intensity of a fire from stretching, the people can be drenched personnel's of fleing's clothing when passing through water smoke simultaneously, prevent the high temperature, and water smoke can also wash the absorption flue gas to the smoke and dust after firing, and form a smokeless space, effectual reduction corridor and the interior smog concentration in the room, avoid personnel of fleing to inhale too much smog and produce and suffocate or faint.
