Abstract
A kind of combined metal sealing ring pad, the made of metal ontology including annular are connected with the Metallic Pairs pad of annular on the internal perisporium of ontology, and the upper and lower end face of Metallic Pairs pad is all covered with the soft seal bed of material, form auxiliary plane sealing structure.The utility model it is structurally reasonable, in addition to ontology can be sealed cooperation, Metallic Pairs pad and equipment joint face also constitute flat seal cooperation, accordingly even when there is sealing cooperation deviation and leaks in the side wall of the trapezoidal annular groove of preprocessing of the oblique side and equipment joint face of ontology, flat seal at Metallic Pairs pad can also make up holding leakproofness, leakage is stopped, the integral sealing reliability of metal ring pads is substantially increased.
Description
Technical field: the utility model relates to the hard sealing rings that the fields such as a kind of industrial container, pipeline use, especially golden
Belong to sealing ring pad.
Background technique: the metal sealing ring pads of hard sealing are distinguished by cross-sectional structure form, it can be common that octagonal and
Two kinds of ellipse.This two kinds of metal ring pads when in use, require the preprocessing ladder for being placed on the equipment joint face such as pipeline, valve
In shape annular groove, the oblique side of ring pads ontology and the side wall pressing contact of trapezoidal annular groove seal cooperation, mutual dimensional fits tolerance
It is more demanding.In actual installation process, in fact it could happen that sealing cooperation it is unreliable and the case where leak, maintenance replacement can reduce life
Efficiency is produced, accessory cost is increased.
Summary of the invention: in view of the deficiencies of the prior art, the utility model provides a kind of structurally reasonable, raising sealing reliability
Combined metal sealing ring pad.
The utility model includes the made of metal ontology of annular, and the Metallic Pairs pad of annular is connected on the internal perisporium of ontology,
The upper and lower end face of Metallic Pairs pad is all covered with the soft seal bed of material, forms auxiliary plane sealing structure.
The utility model it is structurally reasonable, in addition to ontology can be sealed cooperation, Metallic Pairs pad and equipment joint face are also
It may make up flat seal cooperation, accordingly even when the side wall of the trapezoidal annular groove of preprocessing of the oblique side and equipment joint face of ontology occurs
Sealing cooperates deviation and leaks, and the flat seal at Metallic Pairs pad can also make up holding leakproofness, stop leakage, greatly improve
The integral sealing reliabilities of metal ring pads.
The utility model is further illustrated with reference to the accompanying drawings and examples.
Detailed description of the invention: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the portion the I enlarged diagram of Fig. 1.
Specific embodiment: as depicted in figs. 1 and 2, annular made of metal ontology 1 is connected with the gold of annular on internal perisporium
Belong to secondary pad 2, the upper and lower end face of Metallic Pairs pad 2 is all covered with the soft seal bed of material 3, forms auxiliary plane sealing structure.This implementation
It is releasable connection between the ontology 1 and Metallic Pairs pad 2 of example, it, can be by Metallic Pairs in the case where seal request is not very stringent
Pad 2 is removed, and is used merely with ontology 1 as common metal sealing ring pads, save the cost.
When installing and using, preprocessing has trapezoidal annular groove on the connecting flange faces of the equipment such as pipeline, valve, metal ring pads
Ontology 1 is placed in trapezoidal annular groove, and the oblique side of ontology 1 and the side wall pressing contact of trapezoidal annular groove seal cooperation.Metallic Pairs pad 2
Together with plane contact sealing cooperation between the soft seal bed of material 3 and the connecting flange faces of equipment, auxiliary plane sealing structure is formed,
Substantially increase the integral sealing reliability of metal ring pads.As shown in figure 3, the upper and lower end face of Metallic Pairs pad 2 is equipped with several together
The annular stria 4 of the heart, annular stria 4 are also covered by the soft seal bed of material 3, and annular stria 4 generally has three or more, from transversal
It sees to form continuous wave on face, deformable when being pressurized in this way, flat seal is more preferable.
