Abstract
The invention discloses a sealing element. The sealing element comprises a tubular body and is characterized in that the tubular body comprises an inner layer, a buffer layer and an outer layer from inside to outside in the radial direction; multiple positioning protrusions are arranged on the outer layer; the buffer layer is composed of multiple springs; the two ends of the springs are fixed between the inner layer and the outer layer. The sealing element is convenient to position when installed and used, the fixing effect is good, and the sealing effect of the sealing element can be guaranteed.
Description
Technical field
The present invention relates to mechanical fitting technical field, particularly relate to a kind of Sealing.
Background technique
Sealing is the parts sealed, and works the parts of the gas leakage leakage of oil that prevents from leaking.Along with the develop rapidly of modern industrial technology, in order to ensure the safe and stable operation of machinery, requiring that Sealing sealing effect is in use stablized, therefore needing to be improved further the structure of Sealing.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of Sealing, its novel structure, easy to install and use, location and good fixing effect, ensured sealing effect further.
The technical solution adopted in the present invention is: a kind of Sealing, comprise tubular body, it is characterized in that: described tubular body comprises and radially arranges internal layer, buffer layer and skin from the inside to the outside, skin arranges some positioning convex, and buffer layer forms for being individually fixed in spring between internal layer and skin by some two ends.
Particularly, described internal layer is rubber layer, and skin is stainless steel lining.
Particularly, described spring adopts cylindrically coiled spring.
Owing to have employed technique scheme, the present invention has following technique effect: when the present invention uses, and owing to having certain compressibility, good fixing effect, when installing, location is convenient simultaneously, can ensure the sealing effect that Sealing uses.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is structural representation of the present invention.
Embodiment
