Description

A kind of bladder-type portable water mist fire extinguisher
Technical field
The utility model belongs to the fire-fighting fire extinguishing equipment, is specifically related to be applicable to the extinguishing device that uses in the microgravity environments such as spacecraft.
Background technology
Existing fire-fighting fire extinguishing equipment generally takes gas or powder extinguishing chemical to put out fire in the spacecraft in spacecraft.This can cause damage to the instrument and equipment in the spacecraft, environment in pollution and the destruction spacecraft and very difficult the recovery; And bring burden on the huge volume and weight for the emission of spacecraft because of carrying a large amount of extinguishing chemicals; Fine water mist fire-extinguishing system cleaning, efficient.Gas pressure formula fine water mist fire-extinguishing system under the Chang Chongli, because the gravity effect makes same jar of interior water in the bottom, pressure gas provides pressure to make fine water mist fire-extinguishing system work on top by pressed gas; And under the microgravity environment, do not have the gravity effect, and same filling internal pressure gas can not feed water pressure is provided, and the gas pressure formula fine water mist fire-extinguishing system under the Chang Chongli is not suitable for using under microgravity environment.
The utility model content
Can not feed water and provide pressure, the utility model that a kind of bladder-type portable water mist fire extinguisher is provided in order to solve under the microgravity environment same filling internal pressure gas.
A kind of bladder-type portable water mist fire extinguisher, comprise extinguishing chemical supply bag and fire gun, extinguishing chemical is supplied with and is comprised pressure cylinder, on the pressure cylinder bottleneck bottle valve is housed, it is characterized in that: be provided with the extinguishing chemical capsule in the described pressure cylinder, be filled with the anti-flammability gas of compression in the pressure cylinder of extinguishing chemical capsule outside; Draw two paths on the described bottle valve: an end of first via passage is being communicated with in the pressure cylinder, and the other end is being communicated with the turnover gas control valve; One end of second paths is being communicated with the extinguishing chemical capsule, and the other end is the extinguishing chemical outlet, and the extinguishing chemical exit is provided with Pressure gauge and pressure-regulating valve, and the other end of pressure-regulating valve is being communicated with the inlet of fire gun.
Described extinguishing chemical capsule is the bag shape, and its material is withstand voltage rubber or soft plastic material.
Described anti-flammability gas is air or nitrogen or other casual gas.
Described pressure-regulating valve is R114-1/4 " GF gas-liquid pressure regulator valve.
The utility model is to adopt the mode that the extinguishing chemical capsule is installed in the pressurized tank, has realized that extinguishing chemical separates with pressed gas, ejection extinguishing chemical during use.The mode that this fire extinguisher adopts the pressure type fluid to spray makes extinguishing chemical spray with spray pattern, saves extinguishing chemical, the fire-fighting efficiency height.The utility model can be applicable to the most of clean liquid extinguishing chemicals that comprise water.Owing to adopt the extinguishing chemical of atomizing shape to put out a fire, the effect of the oxygen at rapid refrigeration and isolated burning object place is evaporated, played to a large amount of tiny liquid pearls, can extinguish the blaze at short notice; And, replace the liquid extinguisher fire extinguishing that big flow directly waters pouring with the extinguishing chemical of atomizing shape, the consumption of extinguishing chemical is significantly reduced; Simultaneously, the extinguishing chemical of atomizing shape can not conduct electricity yet, so can be used for putting out charged fire.The range of extinguishing chemical is decided by the pressure in pressure cylinder size, is at least 2-3m even can reaches 4-6m or more than the 10m.The utility model volume is little, in light weight, and is easy to use, flexible, clean and effective, the fire extinguishing cost low, be applicable to and put out various indoor outer fire, be particularly useful for incipient fire under microgravity environment inhibition and put out a fire to save life and property.
Description of drawings
