Abstract

The utility model discloses a gas pressurizing device used for the self help in the primary fire of a tall building, which is a set of movable gas pressurizing cabinet 1. A steel cylinder in the pressuring cabinet is connected with an electromagnetic valve 8 and an inverted valve by a pipeline. The outlet end of the inverted valve 9 is connected with a special water storage tank 10 by the pipeline. When the fire just beings, an alarm switch is opened to realize automatic pressurization and provide the water current of high pressure and stable pressure. The problems that an elevated water tank has insufficient water supply pressure, the water supply quantity of atmospheric pressure in a pump type is insufficient and a backup power supply is provided and other problems are solved.

Description

Pressuring means for fire extinguishing

The utility model belongs to fire-fighting equipment, is specifically related to the standby extinguishing device of a kind of high-rise.

All have fire fighting device on the high-rise, particularly I class building, the needs that supply water with satisfy incipient fire time fire extinguishing.At present, the fire fighting supply that China generally adopts has two kinds of forms, and a kind of is elevated tank and water pump combined water supply system, and another kind is a pump formula pressure water supply form, the problem that these two kinds of way of supplying water exist is, the pressure of supply water when the former is difficult to guarantee to put out a fire owing to the placement of water tank is height-limited; The latter is limited because of its pondage, can not satisfy the demand of output, adopts dual power supply, electric power system complexity, cost height because of its start-up control in addition.

The purpose of this utility model is to provide a kind of air pressure supercharging device, depends merely on the hydraulic pressure that high-level tank water exists and the shortcoming of water shortage when solving incipient fire first-aid extinguishing in the high-rise.

Below in conjunction with description of drawings concrete structure of the present utility model.Accompanying drawing 1 is a structural representation of the present utility model.

Critical piece of the present utility model has air pressure supercharging cabinet 1, special-purpose storage Water pot 10 and magnetic valve 8 and 15. Concrete structure is: movably in the gas boosting cabinet 1 inert gas steel cylinder 2 is set, steel cylinder is by connected electromagnetic valve 8 and non-return valve 9 after the pipeline parallel connection, the non-return valve port of export connects water storing tank 10 by pipeline, water storing tank 10 is offered two paths, article one, communicate with inlet pipeline by non-return valve 17 and lock 16, another links to each other with standing elevated tank by magnetic valve 15, the inlet pipeline that communicates with water storing tank 10 again by gate valve 16 ', non-return valve 17 ' be connected fire hydrant. It more than is agent structure of the present utility model, the appurtenances of not referring in the accompanying drawing in addition all belong to conventional current techique category, wherein, 3 chew, 12 be that safety valve, 13 chews, 14 chews for outlet pipe for water inlet pipe for air inlet pipe for low-pressure gage, 11 for low-pressure gate valve, 7 for high pressure sluice valve, 6 for high pressure air gauge, 5 for adjusting control valve, 4.

Dynamic duty process of the present utility model is as follows: when fiery incident is given birth to, press alarm switch, this moment, magnetic valve 15 cut out at first automatically, magnetic valve 8 is opened thereupon, high-pressure inert gas by the road, magnetic valve 8, non-return valve 9 feed water storing tanks 10 pressurizations, and fire hydrant is from gate valve 16 ' and non-return valve 17 ' obtain water for fire extinguishing of high pressure.

When advantage of the present utility model showed high-rise from the beginning of fire, it had both overcome the defective of depending merely on the high-level tank water insufficient pressure, has also solved simultaneously the water shortage that pump formula pressure water supply exists and problem such as stand-by power supply is set.In addition, the utility model is a static pressure because of what adopt, so waterflow stabilization, the hydraulic pressure abrupt change is brought when having avoided fire demand water effectively breathes heavily the shake drawback.

Claims

1, a kind of fire extinguishing air pressure supercharging device, by supercharging equipment, special-purpose reservoir, magnetic valve, gate valve, non-return valve, Pressure gauge and water pipe are formed, it is characterized in that supercharging equipment is to overlap movably gas boosting cabinet 1, inert gas steel cylinder 2 is set in the supercharging cabinet 1, steel cylinder is by the pipeline parallel connection and through decompression, voltage stabilizing is regulated the back and is connected magnetic valve 8 and non-return valve 9, non-return valve 9 ports of export connect special-purpose water storing tank 10 by pipeline, special-purpose water storing tank 10 is offered two paths, article one, communicate with inlet pipeline by non-return valve 17 and gate valve 16, another links to each other with standing elevated tank by magnetic valve 15, the inlet pipeline that communicates with water storing tank 10 pass through again gate valve 16 ', non-return valve 17 ' connection fire hydrant.
