But, the manual Automatic Fire Extinguisher of this structure is not only made difficulty because there are the following problems, even and form product, owing to have potential safety hazard, also be difficult to obtain admission to market by the detection that national statutory body does fire extinguisher according to relevant laws and regulations.1, the pressure vessel withstand voltage is difficult to reach mark: set up automatic valve, need establish the valve block connection holes of an automatic valve newly on pressure vessel wall, therefore, the resistance test of pressure vessel is difficult to up to standard, produces percent defective and required precision and also can correspondingly improve; If adopt special material to make, then can increase substantially production cost.2, because pressure vessel is column, and barrel dliameter is also all less relatively, during actual assembled, the built in suction pipe of at all having no idea to install.Because being a upper end, this built in suction pipe connects firmly on automatic injection valve seal channel, the lower end extends the PVC hard tube that the pressure vessel intracavity bottom is used to carry firing-fighting medium, it is that a upper bend, bottom are the PVC hard tube of straight shape first, second have the built in suction pipe that manual injection valve is required in the pressure vessel, therefore can't be assembled into a built in suction pipe that automatic injection valve is required more at all, cause the manual Automatic Fire Extinguisher of this structure can not form product so far, produce listing.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the present invention aims to provide a kind of manual-auto integrated fire extinguisher, this fire extinguisher integrates the hand automatic fire-extinguishing function, and rational in infrastructure, be convenient to make, the pressure vessel withstand voltage can reach the legal examination criteria of country fully.
For achieving the above object, the present invention has adopted following technical scheme: this manual-auto integrated fire extinguisher, comprise pressure vessel, the foundation ring, manually injection valve and injection valve automatically, pressure vessel is by the middle part cylinder, and be welded on respectively on the cylinder of middle part, upper cover on the lower port and low head constitute, the shape of upper cover and low head is bowl-type respectively, the top drilling of upper cover and manual valve body seat are welded into integral body, it is characterized in that: have a through hole of admitting automatic injection valve valve seat in described low head bottom, automatically injection valve valve seat one end via through holes and low head welding back constitutes integral body, and injection valve is fixedly connected on the another port of described automatic injection valve valve seat automatically.
As to technique scheme further replenish and perfect, the present invention also has following additional technical feature.
Two port planes of described automatic injection valve valve seat are orthogonal, automatically on the horizontal sidewall that is fixedly installed on described foundation ring of injection valve.
The inner port of described automatic injection valve valve seat is exposed shape, directly exposes the bottom at the pressure vessel inner chamber.
