Abstract
The utility model discloses a reinforced seal ring which comprises a cylindrical seal ring body, wherein grooves are respectively formed in the upper and lower circular faces of the seal ring body, the grooves are matched with gratings which are externally connected, and two protruding seal lips are further arranged on the side face of the seal ring body. According to the reinforced seal ring, the grooves and the sealing lips are arranged on the cylindrical seal ring body, so that the problems that seal is untight, displacement is easily caused, service life is short are solved.
Description
Technical field
The utility model relates to a kind of Sealing, is specifically related to a kind of reinforcing sealing ring.
Background technique
In the valve body of water treatment apparatus, between cavity and piston, can add grid, the seal ring of a ring is set between grid, but this seal ring is a kind of individual pen sealing, easily poorly sealed, cause leakage, there is no fixed groove between seal ring and grid, be easy to be subjected to displacement, cause the seal ring off normal, the seal ring thinner thickness, wear and tear than very fast simultaneously, 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 utility model provides a kind of reinforcing sealing ring, has solved poorly sealed, easy displacement and short problem of life-span.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of reinforcing sealing ring, comprise and the seal ring body of annulus cylindricality on the toroidal surface up and down of described seal ring body, respectively be provided with a groove, and described groove and external grid coupling also are provided with the sealing lip of two projections on the side of described seal ring body.
Described groove is circular, and the center of circle of described groove is on the central axis of seal ring body.The seal ring body is connected together by groove and external grid, is not easy to be subjected to displacement.
Described sealing lip is circular, and described seal lip ring is 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, have strengthened sealing effect.
Beneficial effect of the present utility model fruit: 1, the seal ring body be shaped as the annulus post, with traditional seal ring, increased thickness, strengthened working life; 2, on upper and lower toroidal surface, respectively be provided with a groove, the seal ring body is connected together by groove and external grid, is not easy to be subjected to displacement; 3, the side of seal ring body is provided with the sealing lip of two projections, has strengthened sealing effect.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1: a kind of reinforcing sealing ring, the seal ring body 1 that comprises the annulus cylindricality, on the toroidal surface up and down of described seal ring body 1, respectively be provided with a groove 2, described groove 2 mates with external grid, on the side of described seal ring body 1, also is provided with the sealing lip 3 of two projections.
Described groove 2 is circular, and the center of circle of described groove 2 is on the central axis of seal ring body 1.The seal ring body is connected together by groove and external grid, is not easy to be subjected to displacement.
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, have strengthened sealing effect.
Above-described a kind of reinforcing sealing ring when mounted, only need be connected together grid and seal ring to get final product by groove.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
