Abstract
A packing seal comprises a bottom lining, a shell, soft filler, a gland and a shaft sleeve. The outer surface of the bottom lining on a sealing cavity between the shell and the shaft sleeve is made into an inclined face corresponding to the end face of the soft filler (packing). The surface, pressing the end cover, of the outer end face of the soft filler (packing) is made into an inclined face corresponding to the outer end face of the soft filler (packing) as well. In this way, in the pressing process, the soft filler uniformly bears force when pressed and basically does not deform after being pressed. In this way, the soft filler is good in sealing effect, and a shaft bears force uniformly.
Description
Technical field
This technology belongs to motive sealing, is widely used in various pump machines equipment.
Background technique
Present sealing technique, mainly contains traditional packing seal, mechanical seal, pureed sealing etc., and wherein packing seal exists the uneven and axle unbalance stress problem of soft packing compression, causes equipment leakage and axle heel and toe wear.
Summary of the invention
Uneven and the axle unbalance stress problem of soft packing compression is there is in order to solve packing seal, solution of the present invention is: sleeve outer surface at the bottom of the Seal cage between housing with axle sleeve makes the inclined-plane corresponding with soft packing (packing) end face, soft packing (packing) exterior edge face compresses end cover surface and also makes the inclined-plane corresponding with soft packing (packing) exterior edge face, like this when compressing, soft packing compresses uniform force, substantially keep the shape after compression distortion, so not only soft packing seal is effective, axle stressed also more even.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present invention.
Fig. 2 is end sleeve outer surface and A direction view thereof.
In figure: 1, end liner cover, 2, housing, 3, soft packing (packing), 4, gland, 5, axle sleeve.
Embodiment
End liner is housed bottom the Seal cage between figure middle shell 2 and axle sleeve 5 and overlaps 1, fill soft packing (packing) 3 in Seal cage, soft packing (packing) 3 outer end has gland 4 press against, and soft packing (packing) 3 both ends of the surface overlap 1 respectively with end liner, gland 4 liang of inclined-planes are corresponding.
Claims (1)
1. soft packing seal, comprise: end liner cover, housing, soft packing (packing), gland, axle sleeve, it is characterized in that: sleeve outer surface at the bottom of the Seal cage between housing with axle sleeve makes the inclined-plane corresponding with soft packing (packing) end face, soft packing (packing) exterior edge face compresses end cover surface and also makes the inclined-plane corresponding with soft packing (packing) exterior edge face.
