Abstract
A kind of air-bag sealing ring, including the annular body portion made of rubber material and positioned at the elastic balloon layer of annular body portion two sides, the airflow channel of connection elastic balloon layer is equipped in the annular body portion, the outer end of the annular body portion is equipped with the valve of connection airflow channel, inflation/deflation is carried out to control the thickness of elastic balloon layer to elastic balloon layer by valve, is fixedly connected with the rubber sealant being equipped on the outside of the elastic balloon layer.After sealing ring is fit into, pass through the inflation to valve, so that elastic balloon layer expands outward, so that the gap between sealing ring and other parts is constantly decreased to zero, so that product has sealing function, and rubber sealant directly contacts with other components and both improves leakproofness and increase thickness, avoiding other field from directly contacting with elastic balloon layer causes elastic balloon layer to rupture gas leakage.
Description
Technical field
The utility model relates to mechanical seal fields, and in particular to a kind of air-bag sealing ring.
Background technique
Existing sealing ring generallys use rubber material, machinery field components installation connection in application range and its
There is certain flexible upper limit, pass through in the environment of existing application in broadness although existing sealing ring sealing effect is preferable
Often it is easy to appear that gap existing for sealing ring is excessive, sealing ring is insufficient for the elastic pressure of two sides, in this case once
Cavity indoor pressure is excessive, the phenomenon that leakage will occurs.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of air-bag sealing ring:
A kind of air-bag sealing ring, including the annular body portion made of rubber material and positioned at annular body portion two sides
Elastic balloon layer, the interior airflow channel for being equipped with connection elastic balloon layer of the annular body portion, the outer end of the annular body portion
Valve equipped with connection airflow channel carries out inflation/deflation to elastic balloon layer by valve to control the thickness of elastic balloon layer
Degree, the elastic balloon layer outside are fixedly connected with the rubber sealant being equipped with.After sealing ring is fit into, by valve
Inflation, so that elastic balloon layer expands outward, so that the gap between sealing ring and other parts is constantly decreased to zero, in turn
So that product has sealing function, and rubber sealant directly contacts with other components and both improves leakproofness and increase thickness
Degree, avoiding other field from directly contacting with elastic balloon layer causes elastic balloon layer to rupture gas leakage.
It is equipped with axial rubber tube among the annular body portion, is fixedly connected with elastic balloon layer on the outside of the rubber tube,
For preventing from causing elastic balloon layer damaged with elastic balloon layer generation scraping when penetrating spindle-type part.
The utility model has the following beneficial effects: can directly pass through when the gap where finding sealing ring is excessive
Valve is inflated air bag layer, to further fill gap, keeps stable pressure value, and when the gap where sealing ring
When too small, then it can be deflated by valve to air bag layer, consequently facilitating the installation of sealing ring is fixed.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is the diagrammatic cross-section of the utility model.
Attached drawing 3 is the enlarged diagram of A in attached drawing 2.
1 annular body portion, 2 elastic balloon layers, 3 airflow channels, 4 valves, 5 rubber sealants, 6 rubber tubes.
Specific embodiment
The utility model is further described in 1-3 and embodiment with reference to the accompanying drawing.
A kind of air-bag sealing ring, including the annular body portion 1 made of rubber material and be located at 1 two sides of annular body portion
Elastic balloon layer 2, the airflow channel 3 of connection elastic balloon layer 2, the annular body portion 1 are equipped in the annular body portion 1
Outer end be equipped with the valve 4 of connection airflow channel 3, inflation/deflation is carried out to elastic balloon layer 2 to controlling elastic gas by valve 4
The thickness of cystoblast 2 is fixedly connected with the rubber sealant 5 being equipped on the outside of the elastic balloon layer 2.After sealing ring is fit into,
By the inflation to valve 4, so that elastic balloon layer 2 expands outward, so that the gap between sealing ring and other parts is not
Disconnected to be decreased to zero, so that product has sealing function, and rubber sealant 5 is directly contacted with other components and was both improved
Leakproofness increases thickness again, and avoiding other field from directly contacting with elastic balloon layer 2 causes elastic balloon layer 2 to rupture gas leakage.
It is equipped with axial rubber tube 6 among the annular body portion 1, is fixedly connected with elastic balloon on the outside of the rubber tube 6
Layer 2 causes elastic balloon layer 2 damaged when penetrating spindle-type part for preventing with the generation of elastic balloon layer 2 scraping.It is close when finding
When gap where seal is excessive, directly air bag layer can be inflated by valve 4, to further fill gap, protected
Keep steady fixed pressure value, and when the gap where sealing ring is too small, then it can be deflated by valve 4 to air bag layer, from
And it is fixed convenient for the installation of sealing ring.
Obviously, the above embodiments of the present invention is merely to illustrate that examples for clearly illustrating the present invention, and is not
Limitations of the embodiments of the present invention.For those of ordinary skill in the art, on above explained basis
On can also make other various forms of variations or variation.There is no need and unable to give poor example to all embodiments.
And these connotation changes and variations that derived from for belonging to the utility model still fall within the utility model
Protection scope.
