Probe.The galvanic couple of the probe is assemblied in strut, is inserted into guide vane and is carried out temperature test.But by motor piece structure shadow
It rings, the structure of partial engine does not have repacking condition.The means of testing needs to design bend pipe structure temperature probe, is led with being inserted into
It flows in blade support plate.The temperature probe manufacture processing and follow-up assembling of this structure are all time-consuming and laborious, reduce working efficiency.
Invention content
The utility model provides a kind of temperature test probe, to solve at least one existing for existing test method ask
Topic.
In order to achieve the above object, the utility model adopts the following technical solution：
A kind of temperature test probe, which is characterized in that including：
Bolt, on fuel nozzle, the centrally disposed first through hole of the bolt；
K-type armoured thermocouple component, is arranged on the front end of the bolt, and the K-type armoured thermocouple component includes：Armouring
Thermocouple, transfer tube, K-type fluorine packet thermocouple, wherein,
The a diameter of D of armoured thermocouple, described armoured thermocouple one end passes through the first through hole, and is pierced by part
Length is L, draw ratio L/D=(2~3)；
The other end of the K-type fluorine packet thermocouple and the armoured thermocouple welds, and is turned outside junction using described
It takes over and is protected.
Optionally, which is characterized in that pass through insulating cement fit sealing in the transfer tube.
The beneficial effects of the utility model：The temperature test probe of the utility model, directly on the bolt of fuel nozzle
It is transformed, is influenced by the structural factor of engine small；The probe fabricates and assembling is all more convenient, convenient for improving work
Efficiency；Armoured thermocouple is inserted directly into flow field, compared to the structure using strut suit thermo wires, reduces the interference of stream field.

Transfer tube 4 is protected.In the present embodiment, preferably pass through insulating cement fit sealing in transfer tube 4.
The specific implementation method of the temperature test probe of the utility model is, first on aero-engine fuel nozzle 2
Bolt 1 transformation processing, as shown in Fig. 2, the first through hole of work diameter of phi D is added at 1 center of bolt to fuel nozzle 2；Secondly
According to test environment temperature, K-type thermocouple assay is selected.As shown in figure 3, the K-type armoured thermocouple component of design, K-type armouring
Thermocouple assembly is made of armoured thermocouple 3, transfer tube 4 and K-type fluorine packet thermocouple 5.And ensure the total length of armoured thermocouple 3
L1 can be drawn contains casing outside engine.3 thermo wires of armoured thermocouple and 5 thermo wires peer of K-type fluorine packet thermocouple are welded to connect, even
It is protected outside the place of connecing by transfer tube 4, high-temperature insulation glue fit sealing is used in transfer tube 4.By K-type armoured thermocouple
3 one end of armoured thermocouple of component passes through the first through hole of bolt 1, and the length that armoured thermocouple 3 is pierced by 1 part of bolt is L, and
Ensure draw ratio L/D=(2~3).K-type armoured thermocouple component is welded in 1 front end of bolt.So far, the temperature test probe
Processing and manufacturing complete.
The temperature test probe of the utility model, fastening method and lead method are to screw temperature probe by bolt
It is assembled in the bolt 1 of fuel nozzle 2, and the multiple gold of method that the armoured thermocouple 3 of 1 tail portion of bolt is passed through into percussion spot welding
Belong to patch to be fixed on combustion box.In turbine rear casing transformation test lead hole, and sealed with high-temperature seal adhesive.The test
The diameter of fairlead will be capable of providing adequate space to be pierced by test lead and perfusion high-temperature seal adhesive.By armoured thermocouple
3 are drawn out to engine by the test lead hole reequiped on turbine rear casing contains casing, connecting test collecting device outside.
The temperature test probe of the utility model, is directly transformed on the bolt of fuel nozzle, is tied by engine
Structure factor influences small；The probe fabricates and assembling is all more convenient, convenient for improving working efficiency；Armoured thermocouple is directly inserted
Enter in flow field, compared to the structure using strut suit thermo wires, reduce the interference of stream field.
