Description
Technical field:
The invention belongs to fire-fighting equipment and fire-fighting technique field, relate to a kind of self-extinguishing injection valve that the fire-fighting fire extinguishing occasion can be opened fire extinguisher switch and spraying fire-extinguishing agent automatically that is used for, cooperate with various fire distinguishers realization self-extinguishing effect in back is installed.
Background technology:
Along with science and technology and constant development of economy, the task of fire-fighting fire extinguishing is also more and more heavier.It is reported that China every year is because of being lost in more than hundreds billion of units that fire causes, wherein because the fire quantity that spontaneous combustion or the sparking of electric class cause accounts for more than 70%, so the responsibility of fireproofing is very great.At present, machine fire extinguishing two big classes such as the fire prevention fire-fighting work mainly contains manual extinguishing and water spray, sandblasts, spray, and particularly the fire extinguisher of spraying fire-extinguishing agent is used very general, generally all have this fire extinguisher in occasions such as the unit in medium above city, family, hotels, this class fire extinguisher on transit equipments such as automobile, also is equipped with, this fire extinguisher is behind initiation fire, and people can utilize these fire extinguishers in time to put out a fire.But, must open just and can possess the function of carrying out spray fire extinguishing agent by manually starting in accordance with regulations mode of operation when existing these cartridge type fire extinguishers use, the effect that lacks automatic unlatching, in unattended occasion, can not in time open fire extinguisher, particularly the often pointed fire extinguishing point of the fire extinguisher in the vehicles such as automobile and being provided with is installed standby, fire extinguisher if can be in time opened fast and fire can be in time eliminated, even before fire causes, can prevent the eruption of flame, and existing these fire extinguishers can't be realized.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that prior art exists, seek to design a kind of and existing extinguisher structure and cooperate the self-extinguishing injection valve of installing and having automatic unlatching fire extinguisher, can be equipped with corresponding smoke sensing equipment according to actual needs again, fire is eliminated in the automatic injection that adapts under the different condition; Can cooperate to be installed on existing various fire-extinguishing apparatus and the facility, realize eliminating automatically dissimilar fire.
To achieve these goals, self-extinguishing injection valve of the present invention is installed on the extinguishing chemical tank body that has fire extinguisher now and disposes smoke alarm again, make it become a kind of automatic (manually) extinguishing device that in advance is fixed on the relevant position that needs fire prevention fire extinguishing occasion, put out a fire among bud to reach, eliminate the spontaneous combustion harm of equipment such as automobile, guarantee that people's lives and properties avoid infringement.
Agent structure of the present invention comprises that nut, injection valve, injection valve are suitable for reading, nozzle, nozzle carrier, Pressure gauge, pressure gauge stand, spray valve seat, injection valve inner chamber, pin, spool, smoke alarm and helitank; The sealed extinguishing chemical tank body upper oral part that is fixedly mounted on fire extinguisher of injection valve, be shaped on the spool of fall from power formula or back taper formula structure in the injection valve inner chamber, injection valve avris bottom is equipped with Pressure gauge, the horizontal string data in spool top is shaped on pin and is fixed on the injection valve avris nozzle carrier and pressed spool, and the injection valve top is shaped on nut smoke alarm is fixed in the injection valve top end; The round-meshed nut branch in center is contained in injection valve place suitable for reading sealing when being used to inflate, pull down behind the gas of substituting the bad for the good; Or the nut center is shaped on circular hole and connects heating wire circuit and excessive liquids; The injection valve main body is made with metallic copper; Be shaped on screw thread on the injection valve external diameter suitable for reading so that nut to be installed; Screw thread is to install nozzle in being shaped on the nozzle carrier, and nozzle carrier rear wall center and upside respectively are drilled with aperture and are respectively applied for air inlet when pin and inflation are installed; Screw thread is with the setting pressure table in being shaped on the pressure gauge stand, and pressure gauge stand rear wall center has little recessed, and little recessed side has aperture, becomes the logical injection valve inner chamber of 45 degree oblique lines; Be shaped on male thread on the injection valve base to be installed on the helitank; The internal diameter up/down perforation of injection valve inner chamber is ventilated with nozzle carrier, pressure gauge stand respectively, and inner chamber stage casing to injection valve lower edge is the big spool of young cone-shaped or stage body shape down suitable for reading.
Injection valve of the present invention bottom is shaped on the injection valve base, be shaped on the pressure gauge stand of setting pressure table on the avris, corresponding with the pressure gauge stand and be shaped on nozzle carrier on the side at an upper portion thereof, the injection valve top is that injection valve is suitable for reading, injection valve is interior hollow structure, and its inside divides formation injection valve inner chamber; Nozzle is installed on the nozzle carrier; Spool is installed in and is used for air inlet and sealing in the injection valve inner chamber; The power line of smoke alarm connects storage battery or other power supplys, when smokescope acquires a certain degree, smoke detector is reported to the police and also to be made heating wire produce high temperature, and dissolving solids is liquids, and the effect bottom spool of gas pressure moves on rapidly and makes the extinguishing chemical ejection in helitank; Helitank be used for splendid attire extinguishing chemical (dry powder, nitrogen) and with the injection valve fixed seal connection.
The present invention compared with prior art, its mentality of designing novelty, simple in structure, easy to install, adopt the electronic type smoke alarm before naked light forms, to send out the injection office that opens fire extinguisher earlier, prevent fires in not combustion, has the automaticity height, the advantage that fire-fighting fire extinguishing is effective.
