Utility model content
Whether the purpose of this utility model is to provide a kind of thermocouple assembly, and this assembly can make the position of thermopair be fixed, and is convenient to the height of thermopair to change, can detect exactly aluminium sheath and leak gas simultaneously.
For achieving the above object, the utility model provides following technical scheme:
A kind of thermocouple assembly, comprises thermopair and is sleeved on the aluminium sheath on described thermopair, also comprises:
The thermopair Extension Head being connected with described thermopair;
Three-way pipe, the first port of described three-way pipe is communicated with ingot furnace sealing joint, described thermopair and described aluminium sheath enter in described three-way pipe through described the first port, described thermopair Extension Head stretches out from the second port of described three-way pipe, and described thermopair Extension Head is connected with described the second port sealing, the 3rd port of described three-way pipe is connected with vacuum valve.
Preferably, the first port of described three-way pipe and the junction of described ingot furnace interface are set with the lock sleeve for locking described the first port and described ingot furnace interface.
Preferably, between the first port of described three-way pipe and described ingot furnace joint, be set with rubber seal.
Preferably, described three-way pipe is steel three-way pipe.
Can find out from technique scheme, thermopair and aluminium sheath are fixed in three-way pipe, can reach easily by the connection changing between thermopair Extension Head and thermopair the object that changes thermopair height.
Vacuum valve is normally open valve door, in the time that whether detection aluminium sheath leaks gas, ingot furnace is taken out to pressure, if furnace pressure can be reduced to preset value, illustrates that each interface of ingot furnace is all air tight; If furnace pressure cannot be reduced to preset value, illustrate that ingot furnace has interface gas leakage.
In the situation that ingot furnace gas leakage being detected, vacuum valve is closed, then ingot furnace is taken out to pressure, if the force value in ingot furnace still can not be reduced to preset value, illustrate and be not the gas leakage of aluminium sheath, be other interface gas leakage of ingot furnace; If the pressure in ingot furnace can be reduced to preset value, explanation is the gas leakage of aluminium sheath.
Whether the thermocouple assembly in the utility model can make the position of thermopair be fixed, and is convenient to the height of thermopair to change, can detect exactly aluminium sheath and leak gas simultaneously.

Embodiment
Whether the utility model discloses a kind of thermocouple assembly, this assembly can make the position of thermopair be fixed, and is convenient to the height of thermopair to change, can detect exactly aluminium sheath and leak gas simultaneously.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on embodiment of the present utility model, all other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belong to the scope that the utility model is protected.
Please refer to Fig. 1, the exploded view of the thermocouple assembly that Fig. 1 provides for the utility model one specific embodiment.
In the utility model one specific embodiment, thermocouple assembly comprises thermopair 1, aluminium sheath (not shown in FIG.), also comprises thermopair Extension Head 2, three-way pipe 3 and vacuum valve 4.
Wherein, thermopair 1 is for detection of temperature in ingot furnace stove, and aluminium sheath is sleeved on thermopair 1, for avoiding thermopair 1 to be scalded and damage by the high temperature in ingot furnace.Thermopair Extension Head 2 is connected with control system after being connected with thermopair 1 again, and temperature value in stove is transferred to control system.Three-way pipe 3 has the first port 31, the second port 32 and the 3rd port 33.The first port 31 of three-way pipe 3 is communicated with ingot furnace sealing joint, and thermopair 1 and aluminium sheath enter in three-way pipe 3 by the first port 31, after thermopair Extension Head 2 is connected with thermopair 1, passes from the second port 32 of three-way pipe 3.Like this, thermopair 1 and aluminium sheath have just been fixed in three-way pipe 3.The 3rd port 33 of three-way pipe 3 is connected with vacuum valve 4.This vacuum valve 4 is normally open valve.
