Abstract

The invention relates to a multi-point control passive automatic start-stop fire fighting system and belongs to the field of fire fighting equipment. Owning to multi-point detection and control of a fire fighting monitoring valve, a fire behaviour detection blind spot in a region is avoided, and spreading of the fire behaviour is effectively controlled.

Description

Multiple spot is controlled passive automatic open close fire-fighting system

Technical field

Control a passive automatic open close fire-fighting system, belong to fire-fighting automatic control equipment field.

Background technology

Automatic open close sprinkling fire fire-fighting system, is the requisite equipment in modern architecture, this equipment should be able to be when fire occurs automatic spray, can after the condition of a fire is extinguished, automatically close again, when secondary resume combustion appears in the condition of a fire, can move and put out in time again; In patent application in the past, the existing technology that possesses this function occurs, for example 201110430374.3: small-sized self-extinguishing water-curtain system, 200910091188.4: passive remote automatic fire-extinguishing system etc., but in use find still has very large defect when group fills, for example building is comparatively spacious, under the condition of structure relative complex, there will be fire-fighting blind spot, when the multiple spray form of needs, from being designed into construction, be all difficult to realize; If be designed to spray head of a control valve band, the mistake that can attend to one thing and lose sight of another, has affected the effect of fire-fighting.

Summary of the invention

Object of the present invention, is to provide the technical scheme that a kind of multiple spot is controlled passive automatic open close fire-fighting system.

Technical scheme of the present invention is achieved like this: in certain fire-fighting region, multiple spot fire fighting monitoring valve is set, multizone is carried out to multi-point monitoring, when there being a fire valve condition of a fire to be detected, and while opening, all spray heads spray simultaneously; System adopts fire valve valve inleting water mouth in parallel, and little space adopts delivery port series connection, large space to adopt series and parallel connections mutually to have complementation, the basic structure of spray head parallel operation; Spray head can form water curtain; In multiple spot fire fighting monitoring valve one, raises extremely because there is condition of a fire environment temperature, and during higher than set temperature value, valve opening, fire water all spray heads in region spray; After the condition of a fire is extinguished, environment temperature is lower than when setting value, this valve closing, and all spray heads stop water spray; During system works without any need for outer power; Some spray heads form water curtain, for example, water curtain is set on door and window, and water curtain is by the condition of a fire, flue gas and other zone isolation on burning things which may cause a fire disaster ground, and people can, from escape here, evacuate to safe region.

The invention has the beneficial effects as follows, due to the multiple spot Detection & Controling of fire valve, avoided the condition of a fire in region to detect blind spot, effectively controlled spreading of the condition of a fire.

Accompanying drawing explanation

Fig. 1 is a kind of system architecture schematic diagram.

Fig. 2 is another kind of system architecture schematic diagram.

Fig. 3 is to be also another kind of system architecture schematic diagram.

Fig. 4 is the concrete mode of larger area applications.

In accompanying drawing: 1 self-powered type fire valve, 2 open type spray heads, 3 water curtains.

The specific embodiment

The present invention mainly comprises self-operated type fire fighting monitoring valve (1), open type spray head (2), water curtain (3) and corresponding pipeline and valve; Fire fighting monitoring valve (1) can form multiple spray system to adapt to different regions and occasion from open type spray head (2); Accompanying drawing 1, Fig. 2, Fig. 3 are a kind of system architecture schematic diagrames, be applicable to little space mounting application, but because space structure is different, so adopt the water inlet of two above fire fighting monitoring valves of different outlet connected modes to connect into parallel form, be communicated with water source, delivery port is connected with spray head in parallel; Fig. 4 is the concrete mode of larger area applications, and the water inlet of fire fighting monitoring valve still adopts parallel connection, and delivery port series and parallel exists simultaneously, and the top of two fan doors of building forms water curtain (3) by spray head (2); Certain breaking out of fire in region, cause temperature anomaly herein to raise, when environment temperature that fire fighting monitoring valve (1) herein detects is installed higher than predefined valve startup value, valve opening, fire water is through this fire fighting monitoring valve (1) from all mouth sprays (2) ejection, and the shower water of two fan door tops forms water curtain, and water curtain (3) is by the condition of a fire, flue gas and other zone isolation on burning things which may cause a fire disaster ground, people can, from escape here, evacuate to safe region; After the condition of a fire is extinguished, fire fighting monitoring valve (1) cuts out automatically; When fire spreading arrives other, the fire fighting monitoring valve (1) of this point is opened, and all spray heads spray again.

Claims

1. a multiple spot is controlled passive automatic open close fire-fighting system, it is characterized in that, in certain fire-fighting region, multiple spot fire fighting monitoring valve is set, multiple spot in region is carried out to condition of a fire monitoring, and when having a fire-fighting monitor valve condition of a fire unlatching to be detected, all spray heads spray simultaneously; System adopts fire fighting monitoring valve water inlet in parallel, and little space adopts delivery port series connection, large space to adopt series and parallel connections mutually to exist; Certain breaking out of fire in region, cause temperature anomaly herein to raise, when environment temperature that fire fighting monitoring valve herein detects is installed higher than predefined valve startup value, valve opening, fire water through this fire fighting monitoring valve from all mouth spray ejections.

2. multiple spot according to claim 1 is controlled passive automatic open close fire-fighting system, it is characterized in that some spray heads can form water curtain; Water curtain is by the condition of a fire, flue gas and other zone isolation on burning things which may cause a fire disaster ground.
