Description
Technical field
The present invention relates to a kind of temperature thermocouple, and in particular to a kind of temperature thermocouple for gas turbine.
Background technology
Temperature is one of important parameter of gas turbine measurement and control, service life, reliability and the Yi Wei of temperature thermocouple
Shield property is to gas turbine operation and safeguards significant.Due to various gas turbine flow field cross-sectional sizes, shape and distribution not
Together, in the market does not have that ready-made matured product is available, can only by gas turbine development and design unit according to point position,
The dedicated temperature thermocouple of the series of parameters designed, designed such as gaseous-pressure, temperature, flow velocity.As shown in Figure 1, current gas turbine
Temperature thermocouple is simultaneously welded on one as protection pipe, the interior insertion armouring thermo wires of protection pipe using high temperature alloy with mounting flange mostly
The structure risen.Since gas turbine working environment is severe, the thermo wires of thermocouple is fragile (thermo wires open circuit), and replacing thermocouple need to tear open
Open covering disconnects the fuse of mounting screw in the insulating layer of gas turbine outer surface, pulls down mounting screw, extracts what is damaged
Thermocouple, then reverse operating install new thermocouple, and process is cumbersome, time-consuming and laborious.And usually the high temperature alloy of thermocouple is protected
Protecting pipe and mounting base are hardly damaged, and whole branch thermocouple is replaced, and causes great waste.
The content of the invention
The present invention provides a kind of temperature thermocouple for gas turbine, it is intended to when solving to replace thermocouple, without dismounting
Gas turbine insulating layer, only needs to change the armouring thermo wires of thermocouple.The technical scheme is that：
A kind of temperature thermocouple for gas turbine, including protection pipe and armouring thermo wires, the protection pipe outside are equipped with
Mounting flange on gas turbine；The protection pipe upper port is inverted conical；The temperature thermocouple further includes limit
Position ball sealer, the armouring thermo wires is socketed in the position limiting sealed ball and is inserted into the protection pipe, the position limiting sealed
Ball, which is just stuck on the inverted conical face of the protection pipe, forms the temperature thermocouple.
Further, the temperature thermocouple further includes clamp nut, and the clamp nut is located at the position limiting sealed ball
Top, plays the role of limitation and the fixed position limiting sealed ball.
Compared with prior art, the features of the present invention and beneficial effect are：It is convenient that the present invention replaces, and saves the consumption of thermocouple
Material, substantially reduces the maintenance cycle of gas turbine unit, and reduces maintenance cost, effectively improves the economy of gas turbine unit
Benefit.
Brief description of the drawings
Fig. 1 is the structure diagram of traditional temperature thermocouple for gas turbine；
Fig. 2 is the structure diagram of the temperature thermocouple of the present invention；
Wherein, 1- armourings thermo wires, 2- protection pipes, 3- mounting flanges, 4- position limiting sealed balls, 5- clamp nuts.
Embodiment
The present invention is described in further details with specific embodiment below in conjunction with the accompanying drawings, described is the solution to the present invention
Release rather than limit.
As shown in Fig. 2, the specific embodiment of the invention provides a kind of temperature thermocouple for gas turbine, including protection pipe
2 and armouring thermo wires 1, the outside of protection pipe 2 is equipped with the mounting flange 3 being installed on gas turbine；2 upper port of protection pipe
For inverted conical；The temperature thermocouple further includes position limiting sealed ball 4, and the armouring thermo wires 1 is socketed in the position limiting sealed
In ball 4 and it is inserted into the protection pipe 2, the position limiting sealed ball 4 is just stuck on the inverted conical face of the protection pipe 2 i.e. shape
Into the temperature thermocouple；The temperature thermocouple further includes clamp nut 5, and the clamp nut 5 is located at the position limiting sealed
The top of ball 4, plays the role of limitation and the fixed position limiting sealed ball.
The temperature thermocouple of the present embodiment when in use, first welds protection pipe 2 and mounting flange 3, according to armouring thermo wires 1
Temperature-sensitive point expose the design size of protection pipe 2, be inserted into after armouring thermo wires 1 and position limiting sealed ball 4 are socketed in protection pipe 2, will
The terminals of clamp nut 5 from armouring thermo wires 1 penetrate, with protection pipe 2 connect mouth tighten both temperature thermocouple.Then in measuring point
Place's insertion thermocouple, is screwed to mounting flange 3 on gas turbine, outer surface need to be covered when gas turbine works with four mounting screws
Lid insulating layer, insulating layer are applied at the connecting tube of protection pipe 2, the wiring for connecing mouth, clamp nut 5 and armouring thermo wires 1 of protection pipe 2
Expose insulating layer in end.When needing replacing the thermocouple of the present embodiment, without demolition diaphragm gas turbine outer surface insulating layer, need to only twist
Loose clamp nut 5, armouring thermo wires 1 of the extraction with position limiting sealed ball 4, the socket of new armouring thermo wires 1 and position limiting sealed ball 4
Part tightens clamp nut 5 after injecting protection pipe.
And traditional gas turbine temperature thermocouple structure is as shown in Figure 1, its application method is：By protection pipe 2 and installation
After flange 3 welds, armouring thermo wires 1 is inserted into the centre bore of protection pipe 2, after being plugged armouring thermo wires 1 by design length, by armouring thermo wires
1 and protection pipe 2 weld, ultimately form a complete thermocouple.When the thermocouple is installed, thermocouple is inserted at measuring point, is used
Four mounting screws are screwed to mounting flange 3 on gas turbine, and outer surface needs covering and heat insulating layer, Method for Installation when gas turbine works
For orchid 3 in insulating layer, the terminals of only armouring thermo wires 1 expose insulating layer.When needing replacing thermocouple, first have to guarantor
Warm layer is dismantled, and is exposed the mounting flange 3 of thermocouple, is disconnected the fuse of mounting screw, pull down mounting screw, extracts the heat of damage
Galvanic couple, is inserted into new thermocouple, tightens mounting screw and accomplishes fluently fuse, and finally insulating layer is recovered as former state.
In contrast, the temperature thermocouple of the application is more simple in structure and installation process, and dismounting is not had to during replacement
Gas turbine insulating layer, only needs to change the armouring thermo wires of thermocouple, and the consumptive material for saving thermocouple while substantially reduces combustion gas
The maintenance cycle of turbine unit, and reduce maintenance cost.
Although the embodiment of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
Property, it is impossible to limitation of the present invention is interpreted as, those of ordinary skill in the art within the scope of the invention can be to above-mentioned
Embodiment is changed, changes, replacing and modification.
