Abstract
The invention discloses a reinforced sealing ring. The reinforced sealing ring comprises a ring-shaped cylindrical sealing ring body, the upper ring surface and the lower ring surface of the sealing ring body are respectively provided with a groove, which is matched with external barriers; the side surface of the sealing ring body is provided with two protruded sealing lips. By means of the grooves and the sealing lips on the ring-shaped cylindrical sealing ring body, the reinforced sealing ring solves the problems of poor sealing performance, shifting proneness and short service life.
Description
Technical field
The present invention relates to a kind of Sealing, be specifically related to a kind of reinforcing sealing ring.
Background technique
In the valve body of water treatment apparatus, can add grid between cavity and piston, the seal ring of a ring is set between grid, but this seal ring is the sealing of a kind of individual pen, easily poorly sealed, cause leakage, between seal ring and grid, there is no fixed groove, be easy to be subjected to displacement, cause seal ring off normal, seal ring thinner thickness simultaneously, wearing and tearing are than very fast, and the life-span is shorter.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of reinforcing sealing ring, solves poorly sealed, easy displacement and life-span short problem.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of reinforcing sealing ring, comprise the seal ring body of annulus cylindricality, the toroidal surface up and down of described seal ring body is respectively provided with a groove, described groove mates with external grid, the side of described seal ring body is also provided with two protruding sealing lips.
Described groove is circular, and the center of circle of described groove is on the central axis of seal ring body.Seal ring body is connected together by groove and external grid, and displacement is less likely to occur.
Described sealing lip is circular, and described seal lip ring is around on the side of seal ring body, and the center of circle of described sealing lip is on the central axis of seal ring body.In reciprocating motion of the pistons, two sealing lips and piston outer wall are close together closely, strengthen sealing effect.
Beneficial effect of the present invention: 1, the shape of seal ring body is annulus post, adds thickness, enhance working life with traditional seal ring; 2, upper and lower toroidal surface is respectively provided with a groove, seal ring body is connected together by groove and external grid, and displacement is less likely to occur; 3, the side of seal ring body is provided with two protruding sealing lips, strengthens sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1: a kind of reinforcing sealing ring, comprise the seal ring body 1 of annulus cylindricality, the toroidal surface up and down of described seal ring body 1 is respectively provided with a groove 2, described groove 2 mates with external grid, the side of described seal ring body 1 is also provided with two protruding sealing lips 3.
Described groove 2 is circular, and the center of circle of described groove 2 is on the central axis of seal ring body 1.Seal ring body is connected together by groove and external grid, and displacement is less likely to occur.
Described sealing lip 3 is circular, and described sealing lip 3 is looped around on the side of seal ring body 1, and the center of circle of described sealing lip 3 is on the central axis of seal ring body 1.In reciprocating motion of the pistons, two sealing lips and piston outer wall are close together closely, strengthen sealing effect.
Grid and seal ring when mounted, only need be connected together by groove by above-described a kind of reinforcing sealing ring.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
