A fire water pressure circuit control valve for high-rise buildings

Abstract

The invention discloses a fire water pressure loop control valve of a high-rise building and an indoor fire-fighting device thereof. The water pressure loop control valve comprises a water pressure piston pusher and a sealing fire water valve, wherein a fire water valve ejector rod is arranged in the sealing fire water valve, and an outer bushing of the fire water valve ejector rod sleeves the fire water valve ejector rod; a clamping groove is formed in the fire water valve ejector rod, and a hollow clamping groove is formed in the corresponding position of the outer bushing of the fire watervalve ejector rod; and a U-shaped bolt is clamped in the clamping grooves of the fire water valve ejector rod and the outer bushing of the fire water valve ejector rod at the same time and is nested with two ejector pins arranged on the water pressure piston pusher. The fire water pressure loop control valve has the advantages of reasonable structural design and simplicity in operation, the onsite / remote control over the water pressure loop control valve is realized by adopting mechanical and physical principles, the fire behavior of fires of high-rise or super high-rise buildings can be effectively controlled, fire spreading is prevented, and a fire extinguishing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire water pressure circuit control valve of a high-rise building and an indoor fire protection device formed thereof. Background technique [0002] As the population density of modern cities is getting higher and higher, residential buildings, office buildings, and shopping malls are all developing into high-rise and super high-rise buildings. This is also the trend of modern city development. High-rise buildings have many advantages such as occupying less land and accommodating a large population. At the same time, the fire protection of high-rise buildings is also facing a severe test, and the biggest disaster threat and the most common one are fires. However, high-rise buildings that often meet the current fire protection design specifications do not play a timely and effective role when a fire occurs, causing heavy casualties and accidents with huge loss of life an...

AI Technical Summary

Problems solved by technology

[0003] 1. There are many people in high-rise and super high-rise buildings. Once the fire alarm sounds, the first thing is to evacuate the people in the building, and it takes a long time to evacuate people and the corridors are crowded at this time.

[0004] 2. Existing fire-fighting facilities include fire-fighting sprinkler systems and fire hydrants. For example, the sprinkler system works only when the fire is small and the location of the fire point is just right; When a fire breaks out, everyone only cares about escape first, and no one uses fire hydrants to put out the fire; professional firefighters are usually on the way to the fire scene at this time

[0005] 3. The design of high-rise and super-high-rise buildings has many vertical tube wells and other parts. Once a fire occurs, it is easy to produce a "chimney effect" to form a three-dimensional combustion. The fire spreads very quickly. casualties

[0006] If a fire occurs in a high-rise or super-high-rise building, the fire will become uncontrollable when the fire brigade arrives at the fire scene. Although the current fire-fighting equipment is very advanced, the fire-fighting equipment for high-rise or super-high-rise buildings in most cities is extremely Few, and very time-consuming and difficult to mobilize

At this time, the people were still evacuating, and the firefighters could hardly go upstairs. In addition, the spread of the fire made the firefighters not allowed to go upstairs to put out the fire from the inside of the building, causing great losses.
