31 work normally.First brush 24 and the cooperation of the first conductor tube 231, the second brush 25 and the second conductor tube 233 cooperate safety
Height, using effect are good.
Since there are gaps between muff 30 and blade 22, if being not filled with heat-conducting glue between muff 30 and blade 22
32, there are air in the gap between muff 30 and blade 22, and the heating conduction of air is poor, and heat transfer efficiency is slow, can reduce biography
The thermal efficiency.Heat-conducting glue 32 is filled in the gap between blade 22 and muff 30, is not only increased the closure of device, is avoided
Material is entered in the gap between blade 22 and muff 30 by installing gap, has the function of sealing, damping；And it leads
32 good heat conductivity of hot glue, under the action of heat-conducting glue 32, the heat transfer that can quickly generate interior heating sheet 31 to blade
On 22, heat transfer time is short, and heat transference efficiency is high.Wherein, heat-conducting glue 32 can be by inorganic high-temperature resistant glue and heat filling according to 1:(6
~9) ratio is mixed；Wherein, the ZS-1071 type of the optional Beijing will Sheng Weihua Chemical Co., Ltd. of inorganic high-temperature resistant glue is resistance to
Also " high temperature inorganic adhesive " may be selected in high temperature inorganic adhesive, and it is big according to south China science and engineering to be somebody's turn to do " high temperature inorganic adhesive "
Invention disclosed patent (application No. is CN201010154480.9) is learned to be made；Heat filling selects heating conduction excellent
Graphite powder improves the heating conduction of heat-conducting glue 32.Heat-conducting glue 32 can be used filling mode and be injected into blade 22 and muff 30
Between gap in, then 60~80 DEG C at a temperature of toast, accelerate 32 curing molding of heat-conducting glue time.Heat-conducting glue 32 is resistance to
High-temperature behavior is excellent, and structural integrity is still kept at 850 DEG C, softening transform does not occur；The thermal coefficient of heat-conducting glue 32 is greater than
63W/ (mK), the good heat conductivity of heat-conducting glue 32, close to the capacity of heat transmission of iron, the thermal coefficient of iron is 80W/ (mK).
For the electrical safety for guaranteeing equipment, and facilitate installation；It is secondary that the internal diameter of first conductor tube 231 is equal to insulation
The internal diameter of pipe 232, the outer diameter of the first conductor tube 231 are equal to the outer diameter of insulation looped pipeline 232, and insulation looped pipeline 232 is facilitated to lead with first
It is fixedly connected between body pipe 231 by glue or rivet；The internal diameter of the insulation looped pipeline 232 is equal to the second conductor tube 233
The outer diameter of internal diameter, insulation looped pipeline 232 is equal to the outer diameter of the second conductor tube 233, facilitates insulation looped pipeline 232 and the second conductor tube 233
Between can be fixedly connected by glue or rivet；The internal diameter of the insulation supervisor 23 is equal to the internal diameter of the second conductor tube 233, absolutely
The outer diameter of edge supervisor 23 is equal to the outer diameter of the second conductor tube 233, and facilitating can pass through between the second conductor tube 233 and insulation supervisor 23
Glue or rivet are fixedly connected.
Since the heat preservation star discharge valve uses at high operating temperatures, although to take muff 30 heat-insulated for shaft 21,
But under the transmitting of connecting rod, still there is partial heat to be transmitted in shaft 21, causes the temperature in shaft 21 slightly higher；For convenience
Cool down to shaft 21, avoids influencing to drive, the outside of the shaft 21 is provided with the air jet pipe 16 of minimum of one " 7 " shape, jet
