Abstract
The present invention relates to a kind of electronic vacuum pipe, including outer tube, inner tube, vacuum chamber and end cover；Filament, cathode, grid and anode are equipped in the vacuum chamber from the inside to the outside, noncorroding metal layer is coated on said inner tube inner wall, the outer tube is fixedly connected with inner tube by end cover, there is gap between the outer tube and inner tube, it is vacuum in gap, said inner tube outer wall is equipped with one layer of heat absorbing coating；A temperature sensor, a controller and a radiator are also set up for the electronic vacuum pipe, the output terminal of the temperature sensor connects the input terminal of the controller, and the output terminal of the control connects the radiator.Sealing effect of the present invention is good, and corrosion resistance is good, improves efficiency of utilization, when vacuum tube when the temperature is excessively high, radiator can be driven to work automatically, for its reduce temperature, so as to extend the service life of vacuum tube, the reliability of vacuum tube work, popularization easy to use are substantially increased.
Description
Technical field
The invention belongs to electronic component fields, and in particular to a kind of electronic vacuum pipe.
Background technology
Existing vacuum tube confidential letter effect is poor, and corrosion resistance reduces efficiency of utilization, shortens vacuum than relatively low
The service life of pipe causes to greatly reduce the reliability of vacuum tube work.
It is therefore proposed that a kind of electronic vacuum pipe is the subject of the invention to be studied.
Invention content
To solve the disadvantage that prior art corrosion resistance is relatively low, short life, so as to provide a kind of electronic vacuum pipe, including outer
Pipe, inner tube, vacuum chamber and end cover；Filament, cathode, grid and anode, institute are equipped in the vacuum chamber from the inside to the outside
State and noncorroding metal layer be coated on inner tube wall, the outer tube is fixedly connected with inner tube by end cover, the outer tube and
Between inner tube there is gap, be vacuum in gap, said inner tube outer wall is equipped with one layer of heat absorbing coating;
A temperature sensor, a controller and a radiator, the temperature sensor are also set up for the electronic vacuum pipe
Output terminal connect the input terminal of the controller, the output terminal of the control connects the radiator.
Further, the controller includes an AD conversion unit, a storage unit, an identifying unit and a driving
Circuit.
Further, outer tube Limit temperature value is stored in the storage unit, the identifying unit is used to judge that temperature passes
Sensor measure real-time temperature values and Limit temperature value size.
Further, the periphery of the end cover is equipped with sealing ring.
Further, the upper area of the outer tube is equipped with insulating layer.
Further, it is provided with reflective layer on the inner wall of the outer tube lower area.
Further, the noncorroding metal layer is titanium foil.
The present invention has the beneficial effect that relative to the prior art：
The present invention provides a kind of electronic vacuum pipes, and sealing effect is good, and corrosion resistance is good, improves efficiency of utilization, works as vacuum
Pipe when the temperature is excessively high, can drive radiator to work automatically, and temperature is reduced for it, so as to extend the service life of vacuum tube,
Substantially increase the reliability of vacuum tube work, popularization easy to use.
Description of the drawings
Fig. 1 is the module diagram of electronic vacuum pipe of the present invention.

Vacuum tube overtemperature, needs to cool down, and the output terminal of the temperature sensor 7 connects the input terminal of the controller, the control
The output terminal of system connects the radiator.Wherein, specific temperature is stored in storage unit, list is stored when detecting that temperature is higher than
Specific temperature is obtained in member, electric signal is converted to, is transmitted to driving circuit, driving circuit controls radiator 8 to work again, to vacuum tube
Cooling.
In the present embodiment, the outer tube is transparent glass tube.The upper area of the outer tube 2 is equipped with insulating layer, described interior
The length of pipe 1 is less than the length of outer tube 2, and reflective layer is provided on the inner wall of 2 lower area of outer tube.In end cover 4
Periphery is equipped with sealing ring.
The present invention is described in detail above, described above, only the preferred embodiments of the invention, when cannot
Limit the scope of the present invention, i.e., it is all to make equivalent changes and modifications according to the application range, it all should still belong to covering scope of the present invention
It is interior.
