Below with reference to the accompanying drawings and in conjunction with the embodiments describing the invention in detail.
As shown in figure 1, a kind of penetration piece suitable for hot environment, including corrugated tube 4, the upper end and upper end of corrugated tube 4
Flange cylinder 2 is fixed together by welding, and the lower end of corrugated tube 4 is passed through welding with lower end flange cylinder 6 using same method
It is fixed together, upper flanges cylinder 2 is affixed with the upper end of outer tube 3 away from the side wall of 4 axial line of corrugated tube, lower end flange cylinder 6 is remote
Side wall from 4 axial line of corrugated tube is affixed with the lower end of outer tube 3.Fixed plate 5 is connected with by welding on the lateral wall of outer tube 3.
5 points of fixed plate is symmetrical arranged for two groups and two groups, and per group includes two fixed plates 5 and with the fixed plate 5 organized in the outside of outer tube 3
Upper and lower setting on wall.In concreting, fixed plate 5 is cast in concrete walls and plays fixed effect, now run through
Part has been embedded in concrete walls.Corrugated tube 4 is concentric with outer tube 3, for the heat transfer for avoiding accelerator pipe 8 as far as possible
