Abstract
The utility model discloses a tube structure of a carbon dioxide fire extinguisher, comprising a tube body and two solvent reaction chambers arranged in the inner lower part of the tube body and used for producing carbon dioxide, wherein the two solvent reaction chambers are communicated with each other, a control valve is arranged at the communication part, a trumpet-shaped contracting nozzle is arranged at the upper end of each reaction chamber, a rotary handle is arranged at the upper end of the tube body, and the control valve and the rotary handle are controllably connected through a connecting rod. The tube structure of the carbon dioxide fire extinguisher overcomes the defects of the prior art, is simple in design and reasonable in structure, the two solvent reaction chambers are operated and controlled by the control valve, a protective film is arranged at the upper end of each solvent reaction chamber, so that an operator has no need to worry about the dangerous situations caused by the reaction of solvent in the cases of upside down standing or slight collision.
Description
Technical field
The utility model relates to the fire extinguisher technical field, specifically belongs to a kind of carbon dioxide extinguisher tube structure.
Background technology
Two containers are arranged in the foam annihilator, hold two kinds of liquid respectively, they are aluminum sulfate and sodium bicarbonate solution, and two kinds of solution do not contact mutually, and any chemical reaction does not take place.When the needs foam annihilator, fire extinguisher is stood upside down, two kinds of solution mix, and will produce a large amount of carbon dioxides:
Al2 (SO4) 3+6NaHCO3==3Na2SO4+2Al (OH) 3 ↓+6CO2 ↑ Except two kinds of reactants, also added some blowing agents in the fire extinguisher, increase the fire extinguishing effect, but this fire extinguishing can not stand upside down or collide, be not easy to like this in car, place, the placement location fixed form there is certain requirement, seriously influenced its scope of application.
The utility model content
The purpose of this utility model has provided a kind of carbon dioxide extinguisher tube structure; the deficiencies in the prior art have been overcome; simplicity of design; rational in infrastructure; by controlling by the control valve operation between two reaction dissolvents; upper end, reaction dissolvent chamber is provided with diaphragm, does not worry that like this solvent reacts the dangerous situation that causes when handstand or slight impact generation.
The technical solution adopted in the utility model is as follows:
A kind of carbon dioxide extinguisher tube structure, comprise cylindrical shell, the bottom is provided with two solvent reaction chambers that generate carbon dioxide in the described cylindrical shell, be communicated with between two solvent reaction chambers, be communicated with the position and establish control valve, the reative cell upper end is provided with tubaeform contracting nozzle, and the cylindrical shell upper end is provided with turning handle, and control valve is connected control with turning handle by connecting rod.
Described reative cell upper surface is provided with film.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model is by controlling by the control valve operation between two reaction dissolvents; upper end, reaction dissolvent chamber is provided with diaphragm, does not worry that like this solvent reacts the dangerous situation that causes when handstand or slight impact generation; improved its security, and range of application.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of carbon dioxide extinguisher tube structure comprises cylindrical shell 1, and the bottom is provided with two solvent reaction chambers 2 that generate carbon dioxide in the cylindrical shell 1, and reative cell 2 upper surfaces are provided with film 3.Be communicated with between two solvent reaction chambers 2, be communicated with the position and establish control valve 4, reative cell 2 upper ends are provided with tubaeform contracting nozzle 5, and cylindrical shell 1 upper end is provided with turning handle 6, and control valve 4 is connected control with turning handle 6 by connecting rod 7.Rotating operation handle during use, two solvent compartment's internal solvent haptoreactions, the carbon dioxide that reaction generates breaks through film, sprays by contracting nozzle.
Claims (2)
1. carbon dioxide extinguisher tube structure, comprise cylindrical shell, it is characterized in that: the bottom is provided with two solvent reaction chambers that generate carbon dioxide in the described cylindrical shell, be communicated with between two solvent reaction chambers, be communicated with the position and establish control valve, the reative cell upper end is provided with tubaeform contracting nozzle, and the cylindrical shell upper end is provided with turning handle, and control valve is connected control with turning handle by connecting rod.
