Abstract

The invention discloses a piston sealing part. The piston sealing part comprises a sealing part base, an inner ring and an outer ring, the inner ring is arranged on the sealing part base, the outer ring is arranged on the upper portion of the inner ring, a groove is arranged on the outer side of the outer ring, and a check ring is arranged in the groove. The piston sealing part is simple in structure and higher in stability, and is adaptive to larger squeezing clearance of a cylinder block as the outer ring can bear higher force.

Description

A kind of piston seal
Technical field
The present invention relates to rubber-plastic sealing spare field, particularly relate to a kind of piston seal.
Background technique
Piston seal of the prior art only is provided with an inner ring and is arranged on outer ring on the inner ring on its Sealing matrix, therefore, when the cylinder body Gap-Ratios was larger, when the cylinder body relative movement, the outer ring was extruded easily, thereby lost the effect of sealing.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of seal ring of good seal performance.
For achieving the above object, the present invention adopts following technological scheme:
A kind of piston seal comprises the Sealing matrix, and is arranged on the inner ring on the Sealing matrix, and the outer ring that is arranged on inner ring top, described outer ring, and its arranged outside is fluted, is provided with a back-up ring in the groove.
Described outer ring, its outside is a stressed in the other direction side.
In technique scheme, the inner ring on the Sealing matrix, and the outer ring that is arranged on inner ring top, the stressed side of its opposite direction is provided with groove, be provided with a back-up ring in the groove, larger power can be born in the outer ring like this, so as to adapt to cylinder body larger extrude the gap.
Beneficial effect of the present invention is: simple in structure, increased stability, larger power can be born in the outer ring so that adapt to cylinder body larger extrude the gap.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure, 1 is the Sealing matrix, and 2 is inner ring, and 3 is the outer ring, and 31 is back-up ring.
Embodiment
Below by specific embodiment, the present invention is done detailed description.
Referring to Fig. 1, a kind of piston seal, comprise Sealing matrix 1, and be arranged on inner ring 2 on the Sealing matrix 1, and the outer ring 3 that is arranged on inner ring 2 tops, described outer ring 3, its outside is equipped with groove, be provided with a back-up ring 31 in the groove, described outer ring 3, its outside is a stressed in the other direction side.

Claims (2)

1. a piston seal comprises the Sealing matrix, and is arranged on the inner ring on the Sealing matrix, and the outer ring that is arranged on inner ring top, it is characterized in that: described outer ring, its arranged outside is fluted, is provided with a back-up ring in the groove.
2. a kind of piston seal according to claim 1 is characterized in that: described outer ring, its outside be the stressed side of opposite direction.
