Operation principle of the present utility model is：Deformation is produced by frock pressure cap and the mutual crush seal plug of tooling base,
The impact of high pressure can be resisted.
The beneficial effects of the utility model：Compared with prior art, the utility model can 20Mpa pressure, 2500 DEG C
Worked under high temperature, the sealing state of electromagnetic interference, reach measurement maximum temperature transient response time and be about 200ms, meet gunpowder
The technical indicator of burning rise time.Reasonable employment the utility model can truly measure gas generator inside powder burning mistake
The situation of change of temperature in journey, coordinates acquisition software to form real time temperature performance graph, is easy to the analysis of follow-up data.This reality
Also there is assembly and disassembly operations easy to use, simple structure, low manufacture cost, repeatedly used feature with new.
When the utility model is to the powder burning temperature survey of gas generator inside, can be used for stable state during powder burning, move
State temperature survey, coordinates pressure sensor, force value sensor in real time to measure gas generator working condition, is easy to multi-parameter
Mutual analysis under quarter state at the same time.
In addition, being had further the advantage that in the utility model：1st, thermocouple is using tooling base, frock pressure cap, sealing
The relative axle center line position of plug is installed, it can be ensured that thermocouple head will not scratch to gas generator housing in installation process, make
Into damage；2nd, the fixed high-temperature insulation earthenware of tooling base and frock pressure cap inside can fix thermocouple and keep axle center position
Put, insulate and the influence from external disturbance to thermocouple；3rd, the aperture on sealing-plug is consistent with focus dual diameter, it can be ensured that when
Thermocouple can be in close contact when passing through sealing-plug, reduce space, strengthen sealing；4th, in partial portion, especially in groove and
Tongue position uses high temperature resistant silica gel sealing, can strengthen sealing property and positioning function.
