Description
Technical field
The present invention relates to a kind of Detachable cathode test device, this device can be recycled and reused for electron tube hot cathode temperature and electric performance test test.
Background technology
At present, the known hot cathode temp measuring method of electrovacuum industry electron tube has two kinds.Method one, glaze experiment diode inside is connected thermopair and is drawn the temperature by professional instrument, the electric potential difference of measurement being converted into measurement by pin.The method advantage is the impact can identifying cathode material and technique anticathode emitting performance and life-span.Shortcoming is exactly that the local temperature that can only be confined to single-point or multiple spot is measured, and be secondly exactly that cathode for electron tube design temperature needs then will reset when adjusting experiment diode, process seems comparatively complicated.Method two, dress simulates sample pipe envelope glass window leucoscope and carries out temperature survey, the scope of the method measuring tempeature is confined to the visual range of view window, and when electronic tubular construction is more complicated, cost is higher, the waste needing adjustment cathode temperature design dress to simulate sample pipe cost is apparent.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of Detachable cathode test device, this device can be reused, and reduces product development cost.
The present invention in order to the technical scheme solving its technical matters and adopt is: a kind of Detachable cathode test device, comprise quartz bell cover, back up pad, gas outlet and electrode assemblie, described quartz bell cover to be detachably located on described back up pad upper side and to be formed one for the accommodating seal cavity treating thermometric cathode-workpiece, and described gas outlet and electrode assemblie to be fixedly arranged on respectively in described back up pad and to be communicated with described seal cavity.
As a further improvement on the present invention, described electrode assemblie comprises screw rod, the first clamping ring, porcelain tube and the second clamping ring, described porcelain tube is sheathed on the periphery of described screw rod lower end by the first clamping ring, and this screw rod upper end is fixedly arranged in described back up pad by the second clamping ring.
As a further improvement on the present invention, described back up pad comprises upper backup pad and lower supporting plate, and this upper and lower back up pad is fixedly connected with, and is provided with waterpipe between this upper and lower back up pad, and the entrance and exit of this waterpipe is all arranged on described lower supporting plate.
As a further improvement on the present invention, between described quartz bell cover and upper backup pad, O-ring seal is provided with.
The invention has the beneficial effects as follows: a kind of test unit being used in electron tube hot cathode temperature and electric performance test can be provided, can be connected with exhaust station, structure easy accessibility, and can Reusability, for electron tube development bring great convenience while also save cost.
