Abstract
The utility model relates to a sealing piece, in particular to a combination sealing ring which comprises a skeleton and a rubber sealing body and is characterized in that the skeleton and the rubber sealing body are in a split type combination structure. In the combination sealing ring, as the original sealing ring is improved, the combination sealing ring does not have the problems of eccentricity and rubber overflow, therefore, the quality of products can be ensured, the cost is lowered, the efficiency is improved, and the requirements of the actual conditions can be met.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of combined seal ring.
Background technique
Present valve stem packing ring generally is made up of metal frame and rubbery sealed body, is used for the automotive engine valves bar, seals; Its skeleton and rubbery sealed body are integral by sulfuration adhesion, and there is excessive glue in various degree in most product surfaces, and the gluing that overflows is difficult for removing on the skeleton surface, influences quality of product; The more important thing is in process of production, skeleton need simultaneously axially and radially with the mould location, radial location is in order to guarantee and the concentricity of lip, axially locating is in order to reduce the skeleton surface glue that overflows; This just requires the processing of skeleton and mould that very high precision will be arranged, thereby has increased the production difficulty, and is difficult for guaranteeing quality of product, causes the cost-effective rate low.For this reason, need a kind of eccentric and excessive glue problem that do not exist, can guarantee quality of product, reduce cost, the seal ring of raising the efficiency satisfies the needs of actual conditions with this.
The model utility content
A kind of combined seal ring of the present utility model, it has it and does not exist eccentric and the glue problem of overflowing by to the improvement of original seal ring, can guarantee quality of product, reduces cost, and the advantage of raising the efficiency can satisfy the needs of actual conditions.
The technological scheme that the utility model adopted is:
A kind of combined seal ring comprises skeleton and rubbery sealed body, it is characterized in that: skeleton and rubbery sealed body are split type composite structure.
Described combined seal ring, the external diameter groove of rubbery sealed body is the consistent structure of shape with the upper end portion of skeleton.
Like this when work, a kind of combined seal ring of the present utility model, skeleton and rubbery sealed body are split type composite structure, skeleton does not need and the mould location, has only rubbery sealed body to be made by the mould sulfuration, and then rubbery sealed body and skeleton simple combination are got final product, do not exist eccentric and the glue phenomenon of overflowing, guarantee quality of product, reduced cost, improved efficient; The external diameter groove of rubbery sealed body is the consistent structure of shape with the upper end portion of skeleton, and its assembling back is difficult for axially deviating from like this, makes that sealing is more reliable.
A kind of combined seal ring of the present utility model, it has it and does not exist eccentric and the glue problem of overflowing by to the improvement of original seal ring, can guarantee quality of product, reduces cost, and the advantage of raising the efficiency can satisfy the needs of actual conditions.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is original ring structure schematic representation;
Fig. 2 is a kind of combined seal ring composite structure schematic representation of the present utility model;
Fig. 3 is that a kind of combined seal ring of the present utility model is taken back rubbery sealed body structural representation apart;
Fig. 4 is that a kind of combined seal ring of the present utility model is taken the back skeleton structural representation apart.
Among the figure, 1 is skeleton, and 2 is rubbery sealed body, and 3 are the glue that overflows, and 4 is the external diameter groove of rubbery sealed body, and 5 is the upper end portion of skeleton.
Embodiment
Embodiment
As shown in Figure 1, be original seal ring, form, be used for the automotive engine valves bar, seal by skeleton 1 and rubbery sealed body 2; Its skeleton 1 and rubbery sealed body 2 are integral by sulfuration adhesion, and there is excessive glue 3 in various degree in most product surfaces, and the gluing that overflows is difficult for removing on skeleton 1 surface, influences quality of product; The more important thing is in process of production, skeleton 1 need simultaneously axially and radially with the mould location, radial location is in order to guarantee and the concentricity of lip, axially locating is in order to reduce the skeleton surface glue 3 that overflows; This just requires the processing of skeleton 1 and mould that very high precision will be arranged, thereby has increased the production difficulty, and is difficult for guaranteeing quality of product, causes the cost-effective rate low.Fig. 2 is a kind of combined seal ring of the present utility model to shown in Figure 4, comprises skeleton 1 and rubbery sealed body 2, it is characterized in that: skeleton 1 is split type composite structure with rubbery sealed body 2; The external diameter groove 4 of rubbery sealed body is the consistent structure of shape with the upper end portion of skeleton 5.
Like this when work, a kind of combined seal ring of the present utility model, skeleton 1 is split type composite structure with rubbery sealed body 2, skeleton 1 does not need and the mould location, has only rubbery sealed body 2 to be made by the mould sulfuration, and then rubbery sealed body 2 and skeleton 1 simple combination are got final product, do not exist eccentric and glue 3 phenomenons of overflowing, guarantee quality of product, reduced cost, improved efficient; The external diameter groove 4 of rubbery sealed body is the consistent structure of shape with the upper end portion of skeleton 5, and its assembling back is difficult for axially deviating from like this, makes that sealing is more reliable.
A kind of combined seal ring of the present utility model, it has it and does not exist eccentric and the glue problem of overflowing by to the improvement of original seal ring, can guarantee quality of product, reduces cost, and the advantage of raising the efficiency can satisfy the needs of actual conditions.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
Claims (2)
1. a combined seal ring comprises skeleton and rubbery sealed body, it is characterized in that: skeleton and rubbery sealed body are split type composite structure.
2. combined seal ring according to claim 1 is characterized in that: the external diameter groove of rubbery sealed body is the consistent structure of shape with the upper end portion of skeleton.
