Technical field
The utility model relates to a kind of fire extinguisher starting drive, is specifically related to a kind of starting drive of cart type heptafluoro-propane foam annihilator.
Background technology
Fire-fighting equipment is the important weapon that the mankind and fire are struggled, and along with scientific and technical develop rapidly, multi-disciplinary interpenetrating, brought life and vigor to the more new development of fire-fighting equipment.That fire-fighting equipment relates to is wide, kind is many.From the automatic detection warning system of fire, fire extinguisher, fixed fire extinguishing system, pump, car and water supply equipment, personal equipment and lifesaving appliance, communication scheduling command system, until extinguishing chemical, fire-retardant equipment can say that it has comprised the multiple scientific domains such as the metallurgy relevant to national economy, machinery, transmission, light industry, electronics, computer, chemical industry, material.
Along with the extensive use of fire-fighting equipment in fire-fighting work fields such as fire prevention, fire fighting and rescues, whole society prevention and the integral level of resisting fire and other disaster significantly improve, and fire-fighting technology has become important motivity and the guarantee that advances China's fire-fighting career development.Under the drive of the macroeconomy that continues to become better in China and real-estate market environment favourable, the fire-fighting equipment manufacturing of China is faced with unprecedented opportunity to develop.According to " investigation of the 2013-2017 Chinese fire protection equipment manufacturing degree of depth and investment forecasting analysis report " statistics, show, China's fire product market was in the situation of fast development in recent years, 2005-2011 fire-fighting equipment manufacturing income from sales amplification is all more than 14%, and average growth rate per annum reaches more than 24%.
Along with the China's economic sustained and rapid development, overall national strength progressively strengthens the quickening with Process of Urbanization Construction, and governments at all levels are to firemanic great attention, country strengthens year by year to the input of urban fire-fighting equipment, and governments at all levels are annual for buying the expense increase year after year of fire-fighting equipment and goods and materials.Simultaneously, estimate in the coming years that the fire-fighting equipment industry will continue to present rapid growth trend, annual growth maybe will reach 15% to 20%.Conservative expectation, the market scale of fire product in 2012 will reach 85,000,000,000 yuan.Under the promotion that all starts as former government and the public fire-fighting working depth is paid attention to, the fire-fighting equipment industry future also will keep growth rate faster.
Fire extinguisher, claim again fire extinguisher, is a kind of Portable Fire extinguisher.The built-in chemical substance of fire extinguisher, alert in order to rescue fire extinguishing.Fire extinguisher is one of common fireproofing installation, leaves public place in and maybe the place of fire alarm may occur.Because its simplicity of design can be taken, common people also can make for putting out the little fire of firm generation.The built-in composition of different types of fire extinguisher is different, is aim at different fire alarms and establish.
At present, fire-fighting technique need perfect, and the application that fire extinguisher can't be efficient, safe in some field, as low boiling combustible liquid fire in chemical field etc.; The inventor, for the difficult problem of current puzzlement foam fire extinguishing technique, based on to a kind of fire extinguisher starting drive of researching and developing of heptafluoro-propane foam fire-fighting, has improved the fire-fighting efficiency of existing fire-fighting fire extinguishing technology significantly.
The utility model content
The purpose of this utility model is to provide a kind of fire extinguisher starting drive, simply, operation easily and efficiently, guarantees that the heptafluoro-propane fire foam has good fire extinguishing effect.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of fire extinguisher starting drive that the utility model provides, described device for the heptafluoro-propane foam annihilator, comprising: valve 2 and switch 3, its improvements are, the steel cylinder of fire extinguisher is divided into two parts that volume do not wait and described valve is set respectively; Described valve is connected with described switch respectively by conduit, and is connected with described switch by threeway.
Wherein, described steel cylinder is provided with the seal cover connected as one with described valve.
Wherein, described switch is T shape tee ball valve, comprising: valve body, spool, valve seat and valve rod.
Wherein, in described valve body, be provided with spool, described spool is connected with valve rod.
Wherein, described valve is cross, is provided with four interfaces, and wherein two interfaces are connected with described switch, and an interface is connected with described steel cylinder, goes out the agent mouth and is connected with proportioner.
Wherein, the agent mouth that goes out of described valve is connected with proportioner by conduit, and described proportioner is connected with spray gun.
Wherein, described valve, switch and threeway connect and compose loop by conduit.
Compared with prior art, the beneficial effect that the utility model reaches is:
1, the fire extinguisher starting drive that the utility model provides, be consistent the two-part pressure in steel cylinder.
2, the fire extinguisher starting drive that the utility model provides, simple in structure, convenient operation.
3, the fire extinguisher starting drive that the utility model provides, can make heptafluoro-propane and foam drive by standby pressure of nitrogen, improves jet length and the fire-fighting efficiency of extinguishing chemical.
4, the fire extinguisher starting drive that the utility model provides, operating in a key, convenient and swift.
The accompanying drawing explanation
Fig. 1 is: the structural representation of the fire extinguisher starting drive that the utility model provides;
Wherein: 1, conduit; 2, valve; 3, switch; 4, threeway; 5, steel cylinder; 6, steel cylinder; 7, seal cover; 8, go out the agent mouth.
The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
The present embodiment is thought example, and as shown in Figure 1, the fire extinguisher starting drive that the utility model embodiment provides comprises: conduit 1, valve 2, switch 3, threeway 4, steel cylinder 5, steel cylinder 6, seal cover 7, go out agent mouth 8.
