Abstract
The present invention relates to a kind of based on the sensor that measurement superhigh temperature titanium alloy wall temperature is welded and fixed, it is characterised in that: the sensor is connected in sequence by briquetting component (1), thermode component (2), compensating wire (3), tail accessory (4) and plug (5).Briquetting component (1) includes outer laminate panels (6), interior laminate panels (7), outer laminate panels (6) are made of titanium alloy, it can be welded with the titanium alloy at tested wall temperature, interior laminate panels (6), outer laminate panels (7) are fixed by screw in compression.It can realize through the invention and thermode component 2 is welded on titanium alloy structure, realize the measurement to wall temperature.
Description
Technical field
The present invention is applied to aerospace field, suitable for the titanium alloy wall temperature measurement that welding manner can only be used fixed.
Background technique
The advantages that armoured thermocouple is simple with its structure, dynamic response is fast, high mechanical strength, good seal performance is navigated in aviation
Its field is widely used.Existing high temperature resistant armoured thermocouple mostly uses high temperature alloy as armoured thermocouple outer wall, function
Performance is more reliable, more convenient with the connection of stability sensor ontology, therefore is widely applied in high-temperature measurement field.
With the development of material science, Aerospace Products use various high performance alloys more and more to meet its production
Product demand, titanium alloy are widely used because its intensity is high, corrosion resistance is good, heat resistance is high, but titanium alloy is with steel when welding,
Inevitably metallic compound is formed in connector and causes serious embrittlement, so existing armoured thermocouple formula wall temperature sensor is more
It is high temperature alloy or stainless steel when measuring titanium alloy wall temperature, the connection type of welding can not be taken, this strongly limits titanium conjunctions
The measurement of golden wall temperature.
Summary of the invention
Goal of the invention: the present invention is difficult for titanium alloy or the welding measurement of the tube wall temperature of other different-metal material welding performance differences
Topic provides a kind of welding realized at wall temperature sensor and thermometric wall using exchanging structure.
Technical solution: sensor involved in the present invention is mainly attached by briquetting component, thermode assembly, compensating wire, tail portion
The components such as part, plug composition.Realize that structure connects between each components by way of welding, crimping, threaded connection.
It is a kind of based on be welded and fixed measurement superhigh temperature titanium alloy wall temperature sensor, by briquetting component 1, thermode component 2,
Compensating wire 3, tail accessory 4 and plug 5 are connected in sequence.
Briquetting component 1 includes outer laminate panels 6, interior laminate panels 7, and outer laminate panels 6 are made of titanium alloy, can be with tested wall temperature
The titanium alloy at place is welded, and interior laminate panels 6, outer laminate panels 7 are fixed by screw in compression.
Cavity is arranged at outer 6 lower part of laminate panels, and interior laminate panels 7 are located in cavity；
Interior laminate panels 7 are made of high temperature alloy, and interior laminate panels 7 weld together with thermode component 2, and to thermode
Component 2 is protected.
Technical effect: to solve to weld problem, the present invention at thermometric end briquetting component to being designed.It is transferred by this
Structure is, it can be achieved that thermode component 2 is welded on titanium alloy structure, measurement of the realization to wall temperature.
Detailed description of the invention
Fig. 1 sensor structure figure
Fig. 2 briquette structure figure
Specific embodiment
Such as Fig. 1 and Fig. 2, wall temperature sensor involved in the present invention realizes connection in the following ways:
A) pass through welded connecting between briquetting component 1 and thermode component 2；
B) after thermode component 2 and the combination of compensating wire 3 connect, connecting portion is fixed using spring, while right
Junction is protected；
C) compensating wire 3 uses with plug 5 and crimps connection；
D) 4 one end of tail accessory is connected through a screw thread with plug 5, and fluorubber is wrapped up on compensating wire 3 and is coated with glass cloth
Afterwards, compensating wire 3 and 4 other end of tail accessory are fixed.
Key position of the present invention is briquetting component 1, and structure connection is accomplished by the following way between each part of briquetting component 1:
A) thermode component 2 is realized that structure is connect by welding with interior laminate panels 7；
B) interior laminate panels 7 are filled in into outer laminate panels 6 with thermode component 2, is realized and is connected by the screw at outer 6 top of laminate panels
It connects.By this exchanging structure, it can be achieved that thermode component 2 is welded on titanium alloy structure, the measurement to wall temperature is realized.
