Abstract
The utility model discloses an air-blowing thermocouple, which comprises a junction box (17), an adapter (12) and an inner bushing (10). The air-blowing thermocouple is characterized in that the adapter (12) is provided with an air inlet (15) and an air outlet (2). The air inlet (15) is in the same direction with an electrical interface on the junction box (17). The adapter (12) is provided with a sealing unit fixed by a cap (14). Based on the high-efficiency sealing effect of the sealing unit, the service life of the thermocouple is prolonged to equal to or longer than 5 months.
Description
Technical field
The utility model relates to sensor, relates in particular to a kind of blowing thermocouple for measuring temperature in the Circulating Fluidized Bed Boiler.
Background technology
The structural principle of Puffer type thermopair is to consist of certain gas circuit between armoured thermocouple temperature-sensing element and the outside protective pipe; in gas circuit; pass into the inert gas of certain pressure; infiltration with reducing gas under the high temperature of getting rid of or reduce thermopair, the condition of high voltage; Determination of Trace Tantalum is without the adding of element; increased the air-breathing characteristic of Puffer type thermopair, thereby prolonged the serviceable life of armoured thermocouple, for the synthesis of the key temperatures sensor of ammonia complete equipment.Puffer type thermopair Determination of Trace Tantalum has increased the air-breathing characteristic of Puffer type thermopair without the adding of element, thereby has prolonged the serviceable life of armoured thermocouple, for the synthesis of the key temperatures sensor of ammonia complete equipment.But blowing thermocouple is owing to the existence of air intake opening and venthole, and sealing is the difficult problem that the technician need to capture always, and existing thermopair is most not to be fine because of what seal, causes only only have about 3 months the serviceable life of thermopair.
The utility model content
Based on the defects that prior art exists, the purpose of this utility model is a kind of blowing thermocouple, and this thermopair seal construction is reasonable, and can extend to about 5 months serviceable life.
For reaching this purpose, the utility model by the following technical solutions:
A kind of blowing thermocouple that the utility model provides comprises terminal box, adapter and inner sleeve; It is characterized in that described adapter is provided with air intake opening and venthole, and the electric interfaces on air intake opening and the terminal box is positioned at same direction; Described adapter be provided with by and the fixing packoff of cap.
The first preferred blowing thermocouple that the utility model provides, and the number of cap is two, and lay respectively at the both sides of taking over upper venthole and air intake opening.
The second preferred blowing thermocouple that the utility model provides, packoff comprises Graphite pad, female adapter, thread plug, graphite gasket and cupric oxide sealing; One end of described female adapter is connected with terminal box by Graphite pad; The other end of female adapter is connected with joint by screw thread; Described joint by thread plug and graphite gasket with and cap be connected; Described cupric oxide sealing is positioned at adapter, in the passage between adapter and inner sleeve; The end of taking over is provided with plug.
