Abstract

The utility model discloses an ultraviolet phototube. The ultraviolet phototube comprises a cathode and an anode, and is characterized in that the anode is in a net structure; the size of the cathode is matched with the anode; and the cathode and the anode are arranged symmetrically. According to the ultraviolet phototube disclosed by the utility model, by changing the structures of the cathode and the anode, the light-sensing area of the anode is increased, the ultraviolet radiation receiving area is increased, and the ultraviolet phototube has the advantages of high sensitivity, stability and reliability.

Description

A kind of ultraviolet phototube
Technical field
The utility model relates to a kind of photoelectric tube, relates in particular to a kind of highly sensitive ultraviolet phototube that has.
Background technology
Photoelectric tube is a kind of basic electrooptical device based on external photoelectric effect.Photoelectric tube can make light signal convert the signal of telecommunication to.Photoelectric tube is divided into two kinds of vacuum photo tube and gas cells.The typical structure of photoelectric tube is that the spherical glass shell is evacuated, and is coated with one deck photoelectric material as negative electrode at interior hemisphere face, and centre of sphere placement pellet shapes or little endless metal are as anode.Just become gas cell if fill low-pressure inert gas in the ball.Photoelectron makes gas ionization with gas molecule collision in flying to the process of anode, can increase the sensitivity of photoelectric tube.Metal as photocathode has alkali metal, mercury, gold, silver etc., can be fit to the needs of different-waveband.
In recent years because improving constantly of ultraviolet flame Detection Techniques makes system avoid the complex background that the most powerful lamp causes, so that the burden of information processing greatly alleviates in system.So reliability is higher, it is the photon detection means in addition, thereby signal to noise ratio is high, has atomic Testing of Feeble Signals ability, and in addition, it also has the characteristics that the reaction time is exceedingly fast.Compare with Infrared Detectors, ultraviolet detector is more reliable, and has the characteristics such as high output, high response speed and application circuit are simple.Thereby ultraviolet phototube is applied to burning monitoring, fire in warning, discharge examination, UV detection and ultraviolet controller for electric consumption just increasingly extensively.
The ultraviolet phototube of prior art is owing to structural design and preparation technology's restriction, and its noise and sensitivity are mutual conflicting parameters.Generally speaking, need sensitivity is controlled at a suitable level, too high sensitivity is very difficult to the low noise index of device, because sensitivity and noise signal all are to be sent by photosensitive tube, traditional detector can amplify two kinds of signals simultaneously.So its remolding sensitivity is relatively poor, it is little to detect distance, and there is certain rate of false alarm in interference that can not anti lightning.
Granted publication number is CN 202259155U, Granted publication day is that the Chinese patent literature on May 30th, 2012 discloses a kind of day blind type inflation ultraviolet phototube, it is characterized in that: comprise stem stem, negative electrode, anode and glass shell, described stem stem comprises glass base, metallic struts and blast pipe, metallic struts is passed glass base and is fixed on the glass base, blast pipe then is arranged on the centre of glass base, described anode and negative electrode are fixed on the metallic struts top of stem stem, and anode and negative electrode upwards be arranged in parallel at hard Nogata, in addition, the glass base sealing-in of above-mentioned glass shell and stem stem is fixed.This patent documentation is because negative electrode and anode are filament, and the anode photosensitive area is less, and it is less to receive the ultra-violet radiation area, causes sensitivity lower, is subject to the special light sources interference generation wrong reports such as sunlight.
The utility model content
The utility model is in order to overcome the defective of above-mentioned prior art, a kind of ultraviolet phototube is provided, and the utility model increases the anode photosensitive area by changing the structure of negative electrode and anode, thereby increased the ultra-violet radiation receiving area, had high sensitivity, reliable and stable characteristics.
The utility model is achieved through the following technical solutions:
A kind of ultraviolet phototube comprises negative electrode and anode, it is characterized in that: described anode is network structure, and described negative electrode size is suitable with anode, and negative electrode and anode are arranged symmetrically with.
Also comprise glass shell, blast pipe, pass the glass shell diapire and be fixed on metallic struts on the glass shell diapire, described negative electrode and anode are fixed on the metallic struts top.
Described anode cross section is " U " type.
Described negative electrode and anode are metallic nickel.
Described glass shell is that ultraviolet sees through quartz glass.
The beneficial effects of the utility model are mainly manifested in the following aspects:
One, the utility model and Granted publication number are CN 202259155U, Granted publication day is that the Chinese patent literature on May 30th, 2012 is compared, because anode is network structure, the negative electrode size is suitable with anode, negative electrode and anode are arranged symmetrically with, and the anode photosensitive area is increased, thereby increased the ultra-violet radiation receiving area, the sensitivity that has closely improved photoelectric tube prevents that effectively other lamp from disturbing the wrong report that causes.
Two, the utility model and Granted publication number are CN 202259155U, and Granted publication day is that the Chinese patent literature on May 30th, 2012 is compared, and the anode cross section is " U " type, effectively increases glazed area, improve sensitivity, strengthen stability.
Three, the utility model and Granted publication number are CN 202259155U, Granted publication day is that the Chinese patent literature on May 30th, 2012 is compared, negative electrode and anode are metallic nickel, to the not response of radiation of daylight and room lighting light source, have effectively avoided the interference of other signals.
Four, the utility model and Granted publication number are CN 202259155U, and Granted publication day is that the Chinese patent literature on May 30th, 2012 is compared, and glass shell is that ultraviolet sees through quartz glass, has good transmitance in UV wavelength range.
Therefore, no matter the utility model and this Chinese patent literature are from technical scheme, or all there is obviously difference on the technique effect that reaches.
