Gas inlet opening, to restore to the original state, combustion gas can be normal through.
Preferably, the memory metal spring and common metal spring, which mutually spiral, mutually twists composition multiple twin spring structure；It should
One end of multiple twin spring is fixedly connected with plug, and the other end is fixedly connected with fixed frame.
Preferably, the memory metal spring and common metal spring are respectively arranged at the opposite two sides of plug, connect respectively
Connect plug and fixed frame.
Preferably, the plug is taper plug, and tapered one end is for stretching to gas inlet opening for gas inlet
Opening is blocked.
Preferably, the inside edge of the gas inlet opening corresponds to taper plug equipped with chamfering inclined surface.
The beneficial effects of the utility model are: a kind of fireproof tempering device of the utility model, is arranged plug in mixing chamber
And fixed frame, and length when extension, room temperature when being connected between plug and fixed frame the high temperature made of memory metal
The memory metal spring of shortening and the little common metal spring of the high/low temperature Flexible change made of common metal；In room temperature
When, plug is pulled away from gas inlet opening without elasticity, by common metal spring by memory metal, and combustion gas can be normal through；
When being tempered, heat can be such that spring temperature increases, this does not influence the elasticity of common metal spring, but memory metal spring
Elasticity sharply increase and be more than the elastic force of common metal spring, the elongation of memory metal spring keeps plug mobile and goes out combustion gas
Mouth is blocked；After troubleshooting, spring temperature is reduced, and the elastic force of memory metal spring disappears, the elastic force of common metal spring
Effect gradually embodies, and plug is pulled away from gas inlet opening, to restore to the original state, combustion gas can be normal through；Device can be certainly
Dynamic cutting combustion gas can also restore to the original state automatically, do not need manually to reset, reduce the workload of maintenance, the stabilization of equipment
Property is more preferable.
