Surface attachment inside the internal layer end cone has high-temperature resistant coating, and the top of the high-temperature resistant coating is provided with gas outlet, described
The bottom of high-temperature resistant coating is provided with connectivity port, and bayonet is provided with the connectivity port.
As a kind of optimal technical scheme of the utility model, the outer layer end cone and internal layer end cone are disposal vacuum pressure
Conjunction is made, and the high-temperature resistant coating is made for inorganic compound.
As a kind of optimal technical scheme of the utility model, the shape of the internal layer end cone is interior convex.
Compared with prior art, the beneficial effects of the utility model are as follows：
The utility model is attached to internal layer end cone using refractory inorganic paint, can play heat-resisting, erosion-resisting effect, interior
Convex design in layer end cone, can make noise play noise reduction by internal consumption, double-deck end cone and heat-insulated vacuum space can be effective
Play heat-insulated effect.
