Abstract
The present invention relates to a kind of Inflatable ultraviolet phototubes, comprising: glass base, exhaust pipe, cathode, anode, guide pin and high silicon oxygen transitional glass shell；The glass base is fixed with high silicon oxygen transitional glass shell sealing-in；The guide pin is through glass base and is fixed in glass base；The exhaust pipe is arranged at glass base center；The cathode, anode are arranged at the top of guide pin；The cathode is semi-cylindrical in configuration；It is only to generate photoelectric effect to the ultraviolet radiation of 185nm-260nm spectral region, thus do not influence on the light wave for reaching the sunlight on ground under atmosphere, and be easily installed that anode of the invention, which uses,.
Description
Technical field
The present invention relates to field of photoelectric technology more particularly to a kind of Inflatable ultraviolet phototubes.
Background technique
Flame radiation is the gas radiation with discrete spectrum and the solid radiative with continuous spectrum, and wavelength exists
0.1 μm~10 μm or broader range, in order to avoid the interference of other signals, Chang Liyong wavelength is less than the ultraviolet radioactive of 300nm,
Or in flame CO2 radiation spectrum of the distinctive wavelength near 4.4 μm as detectable signal.
UV sensor only responds the ultraviolet radioactive in 185nm~260nm narrow range, and to other frequency spectrums
The light of range is insensitive, can be detected to the ultraviolet radioactive in flame using it.Ultraviolet detector is more reliable, and has
There are the features such as highly sensitive, high output, high response speed and application circuit are simple, thus the sensing element as ultraviolet detector
Inflation ultraviolet phototube become increasingly widespread be applied to combustion monitor, fire from alarm, discharge examination, UV detection and
In ultraviolet controller for electric consumption.
Summary of the invention
The purpose of the present invention is to provide a kind of inflation ultraviolet phototubes being easily installed.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of Inflatable ultraviolet phototube, comprising: glass base, exhaust pipe, cathode, anode, guide pin and high silicon oxygen transition
Glass shell；The glass base is fixed with high silicon oxygen transitional glass shell sealing-in；The guide pin is through glass base and is consolidated
It is scheduled in glass base；The exhaust pipe is arranged at glass base center；The cathode, anode are arranged at the top of guide pin；Institute
Stating cathode is semi-cylindrical in configuration.
Further, cathode is antimony caesium cathode.
Further, cathode and anode are fixed by welding.
Further, anode material is only photoelectric to the ultraviolet radiation generation of 185nm-260nm spectral region
Metallic nickel.
The present invention has the advantages that anode of the invention is using being the only ultraviolet light spoke to 185nm-260nm spectral region
Generation photoelectric effect is penetrated, thus the light wave for reaching the sunlight on ground under atmosphere is not influenced, and is easily installed.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Attached drawing 1 shows a kind of Inflatable ultraviolet phototube structural schematic diagram of embodiment according to the present invention.
Appended drawing reference: 1, glass base；2, exhaust pipe；3, cathode；4, anode；5, guide pin；6, outside high silicon oxygen transitional glass
Shell.
Specific embodiment
In the following detailed description, many details are proposed, in order to complete understanding of the present invention.But
It will be apparent to those skilled in the art that the present invention can not need some details in these details
In the case of implement.Below to the description of embodiment just for the sake of provided by showing example of the invention to it is of the invention more
Understand well.
Below in conjunction with attached drawing, the technical solution of the embodiment of the present invention is described.
As shown in Figure 1, the present invention provides a kind of Inflatable ultraviolet phototube, comprising: glass base 1, exhaust pipe 2, cathode
3, anode 4, guide pin 5 and high silicon oxygen transitional glass shell 6；The glass base 1 and high 6 sealing-in of silicon oxygen transitional glass shell are solid
It is fixed；The guide pin 5 is through glass base 1 and is fixed in glass base 1；The exhaust pipe 2 is arranged at 1 center of glass base
Place；The cathode 3, the setting of anode 4 are at 5 top of guide pin；The cathode 3 is semi-cylindrical in configuration.
According to an aspect of the present invention, cathode 3 is antimony caesium cathode 3.
According to an aspect of the present invention, cathode 3 and anode 4 are fixed by welding.
According to an aspect of the present invention, 4 material of anode is only to produce to the ultraviolet radiation of 185nm-260nm spectral region
Raw photoelectric metallic nickel.
It is only to generate photoelectric effect to the ultraviolet radiation of 185nm-260nm spectral region that anode 4 of the invention, which uses, because
And the light wave for reaching the sunlight on ground under atmosphere is not influenced, and is easily installed.
The present invention is not limited to examples detailed above, in claims of the present invention limited range, art technology
The various deformations or amendments that personnel can make without creative work are protected by this patent.
