Description
Technical field
The utility model is related to a kind of discharge tube, specifically a kind of decompression protection gas discharge diode.
Background technology
At present, common discharge diode typically all includes insulation tube and two electrodes in insulation tube, when putting
When fulgurite both end voltage reaches certain value, discharge tube is breakdown to make high current by so as to protect electric equipment normally to use, existing
Some discharge tubes are not always at a stable environment in use, that is to say, that the discharge tube breakdown time and
Electric current is simultaneously unstable, and discharge tube is easily damaged when electric current is excessive or the electric current elapsed time is long, or even causes fire etc.
Unsafe condition, in addition, existing discharge tube also has capacitance problems of too.
The content of the invention
The technical problems to be solved in the utility model is to provide one kind and can carry out pressure release to discharge tube, so as to ensure to use
The decompression protection gas discharge diode of safety.
In order to solve the above-mentioned technical problem, decompression protection gas discharge diode of the present utility model, including by insulation tube,
Set in the seal cavity and insulation tube of the seat of honour installed in insulation tube upper end and the lower seat formation installed in insulation tube lower end
The Top electrode on the seat of honour put and the bottom electrode on lower seat, annular seal space are filled with inert gas medium；
Oxide coating is coated with Top electrode and the relative end face of bottom electrode, Top electrode is weldingly fixed on the seat of honour by solder,
Bottom electrode is weldingly fixed on lower seat by solder, between Top electrode and the seat of honour formed upper trapezoid cavity, bottom electrode and lower seat it
Between formed inferior pyramidal cavity, the gas channel that upper conical cavity can be made to be communicated with seal cavity, bottom electrode are provided with Top electrode
On be provided with the gas channel that inferior pyramidal cavity can be made to be communicated with seal cavity, be provided with the seat of honour just to the upper of upper trapezoid cavity
Check valve, is provided with the lower check valve just to lower trapezoid cavity on lower seat.
The shape of the Top electrode and bottom electrode is the frustum shape that upper end is smaller, lower end is larger.
The gas channel is arranged at the middle part of Top electrode and bottom electrode and extends to top both sides.
After using above-mentioned structure, due to be respectively provided with upper/lower electrode cone-shaped cavity, be provided with upper and lower seat it is unidirectional
The gas channel opened up on valve and upper/lower electrode, thus when discharge tube undergoes larger current or long-time excessively stream heats up, can
By check valve open be exhausted, and cone-shaped cavity the smooth exclusion being designed with beneficial to gas, improve use can
By property, in addition, upper/lower electrode is weldingly fixed on upper and lower seat by solder respectively, directly avoid two electrodes direct with insulation tube
Contact, reduce further electric capacity.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model decompression protection gas discharge diode.
Specific embodiment
With reference to the accompanying drawings and detailed description, decompression protection gas discharge diode of the present utility model is made into one
Step is described in detail.
As illustrated, decompression protection gas discharge diode of the present utility model, including by insulation tube 1, installed in insulation
Seal cavity and the interior peace for setting of insulation tube 1 that the seat of honour 2 of the upper end of pipe 1 and the lower seat 3 installed in the lower end of insulation tube 1 are formed
The shape of the Top electrode 4 on the seat of honour 2 and the bottom electrode 5 on lower seat 3, Top electrode 4 and bottom electrode 5 is upper end
The larger frustum shape in smaller, lower end, reduces electric capacity, and annular seal space is filled with inert gas medium；Top electrode 4 and bottom electrode
Oxide coating 6 is coated with 5 relative end faces, Top electrode 4 is weldingly fixed on the seat of honour 2 by solder, and bottom electrode 5 is logical
Cross solder to be weldingly fixed on lower seat 3, upper conical cavity 7 is provided with Top electrode 4, as seen from the figure, upper conical cavity 7 is formed
Between Top electrode 4 and the seat of honour 2, bottom electrode 5 is provided with inferior pyramidal cavity 8, and as seen from the figure, inferior pyramidal cavity 8 is formed at lower electricity
Between pole 5 and lower seat 3, the gas channel that upper conical cavity 7 can be made to be communicated with seal cavity, bottom electrode 5 are provided with Top electrode 4
On be provided with the gas channel that inferior pyramidal cavity 8 can be made to be communicated with seal cavity, be provided with the seat of honour 2 just to upper trapezoid cavity 7
Upper check valve 9, the lower check valve 10 just to lower trapezoid cavity 8 is provided with lower seat 3.
Further, gas channel is arranged at the middle part of Top electrode 4 and bottom electrode 5 and extends to top both sides, by scheming
It can be seen that, gas channel extends from the both sides of Top electrode 4 and bottom electrode 5, it is possible thereby to be conducive to the circulation of gas.
