Accompanying drawing explanation
Fig. 1 is the schematic front view of one preferred embodiment of this utility model.
Diagram sequence number:
1 filler box body, 2 glands, 3 filling bodies, 4 springs, 5 shroudings, 6 sealing rings, 7 exterior seal rings,
31 holding tanks, 32 grooves.
Detailed description of the invention
As it is shown in figure 1, this hot blast regulation Circular ventilation door axle head composite sealing assembly disclosed in the present embodiment, including stuffing box
Body 1, gland 2, filling body 3, spring 4, shrouding 5, sealing ring 6 and exterior seal ring 7；Wherein filling body 3 is bronze rounding cylinder, in it
Footpath is matched with the external diameter of valve shaft 4, its external diameter is matched with the internal diameter of filler box body 1, and filling body 3 has two, axial along rotary shaft
Positioned opposite, the axial outer end inner wall of end of filling body 3 be provided with place on the holding tank 31 of sealing ring 6, outer wall axial interior
End is provided with the groove 32 for placing exterior seal ring 7, and the material of sealing ring 6 and exterior seal ring 7 is graphite；Shrouding 5 is positioned to be filled out
The material axial two ends of body 3, wherein the shrouding 5 of one end and filler box body 1, between the shrouding 5 of the other end and gland 2 all by spring 4
Being connected, gland 2 is connected locking by bolt with filler box body 1.
The present embodiment makes this utility model the most not only by arranging sealing ring holding tank on the inwall of filling body
