Abstract
The utility model discloses a strengthened engine sealing ring. The strengthened engine sealing ring comprises a ring body. The ring body is in a three-layer structure and a sealing layer, a strengthened layer and a fitting layer are arranged from top to bottom in sequence. Annular circular arc protrusions are installed on the upper surface of the ring body and corresponding annular circular grooves are formed in the lower surface of the ring body. The ring body of the strengthened engine sealing ring is in the three-layer structure and can preferably conduct fitting and sealing to components. The annular circular arc protrusions are installed on the upper surface of the ring body and the corresponding annular circular grooves are formed in the lower surface of the ring body. When the strengthened engine sealing ring is used, the protrusions are planished so as to be further fitted with a sealing face. Meanwhile, the strengthened layer can improve overall resistant strength.
Description
Technical field
The utility model relates to a kind of mechanical part, relates in particular to a kind of enhanced locomotive seal ring.
Background technique
The joint seal request of engine exhaust pipe and pressurized machine is high, and temperature is also very high.In prior art, the ring packing pad of a kind of surfacing take the expanded graphite composite sheet as material is generally adopted in this joint, and its deficiency is when gas temperature acquires a certain degree, and sealing effect can be affected, and has increased simultaneously maintenance cost.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of enhanced locomotive seal ring.
To achieve these goals, the technical solution adopted in the utility model is: a kind of enhanced locomotive seal ring, comprise circle body, circle body is three-decker, be followed successively by from top to bottom sealing layer, reinforced layer and laminating layer, the upper surface of circle body is provided with the projection of ring-type circular arc, and lower surface is provided with the groove of the corresponding ring-type circular arc of projection.
As preferably, reinforced layer is titanium alloy layer.
Compared with prior art, the utility model has the advantage of: modern design, circle body is three-decker, better parts fitted and seal, the upper surface of circle body is provided with the projection of ring-type circular arc, and lower surface is provided with the groove of the corresponding ring-type circular arc of projection, during use, projection is driven plain, and further fits tightly with sealing surface, and reinforced layer improves whole anti-shock strength simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 11, sealing layer; 12, reinforced layer; 13, laminating layer; 21, projection; 22, groove.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As a kind of mode of execution of the present utility model, consult Fig. 1, the utility model comprises circle body, circle body is three-decker, be followed successively by from top to bottom sealing layer 11, reinforced layer 12 and laminating layer 13, the upper surface of circle body is provided with the projection 21 of ring-type circular arc, and lower surface is provided with the groove 22 of projection 21 corresponding ring-type circular arcs.Reinforced layer 12 is titanium alloy layer.
Circle body of the present utility model is three-decker, better parts fitted and seal, the upper surface of circle body is provided with the projection 21 of ring-type circular arc, lower surface is provided with the groove 22 of projection 21 corresponding ring-type circular arcs, during use, projection 21 is driven plain, and further fits tightly with sealing surface, and reinforced layer 12 improves whole anti-shock strength simultaneously.
Although be recognized as a most practical and preferred embodiment and described the utility model in conjunction with current, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended on the contrary contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims.
