Problems solved by technology

[0004] The above-mentioned compressed air foam automatic fire extinguishing system has the disadvantage of a long compressed air foam delivery pipe network, so it takes a long time from the alarm to start the system to spray foam, the system responds slowly, and it is easy to miss the best fire extinguishing opportunity
[0005] In addition, the main components of the above-mentioned compressed air foam automatic fire extinguishing system, such as the foam generating device for centralized preparation of compressed air foam, are all concentrated on the main engine, which makes the system huge and takes up a lot of space. The actual installation requires high site structure layout and space size.

Embodiment Construction

[0023] Further illustrate the present invention below in conjunction with embodiment and accompanying drawing.

[0024] Such as figure 1 The partition control boxes shown are distributed in the fire protection area, and the housing 1 of each partition control box is respectively provided with a water supply branch pipe 2, a foam liquid input branch pipe 5 and an air supply branch pipe 9.

[0025] The water supply branch pipe 2 is connected with the water supply main pipe, and the water supply branch pipe is connected with the first signal butterfly valve 3 and the deluge valve 4 in sequence, and the outlet of the deluge valve 4 is connected to the water inlet of the foam proportional mixer 8 .

[0026] The foam liquid input branch pipe 5 is connected with the foam liquid output main pipe of the foam liquid storage tank, and the foam liquid input branch pipe 5 is connected with the first solenoid valve 6 and the first one-way valve 7 in turn, and the first solenoid valve 6 is p...

Abstract

The invention discloses a compressed air foam zone control cabinet which can be distributed in a large-space fireproof place. Corresponding branch pipes of the zone control cabinet are communicated with a main water supply pipe, a main foam liquid output pipe and a main air supply pipe respectively. In this way, the compressed air foam zone control cabinet can realize zone control and the rapid response mode that compressed air foams are generated immediately on fire scenes, and the time for conveying compressed air foams in a conveying pipe is greatly shortened. The compressed air foam zone control cabinet has the remarkable effects of giving a rapid response when a fire breaks out and putting out a fire rapidly in the initial stage.

Description

technical field [0001] The invention belongs to a fire automatic fire extinguishing system, in particular to a compressed air foam partition control box suitable for fire extinguishing in a large space. Background technique [0002] Compressed air foam fire extinguishing is a new type of foam fire extinguishing technology gradually developed in recent years. It generates foam by injecting air into the foam solution under positive pressure. The compressed air foam structure is dense and uniform, with long liquid separation time and high stability, and can cover the surface of the protected object for a long time. Compared with the existing water-based fire extinguishing technologies such as water spray, foam-water spray, etc., compressed air foam has the following outstanding advantages: (1) High fire extinguishing efficiency for Class A and Class B fires, small water consumption, suitable for It is used in places where water resources are scarce; (2) the foam performance is...
