Abstract
It is a kind of for the slim adsorption type seal ring without the sealing of groove flange face that the utility model provides, there is O RunddichtringO, on two working surfaces of described O RunddichtringO, symmetry is shaped with V-type adsorption tank, two hypotenuses of described V-type adsorption tank are 35 degree angles, the exterior edge face of described two hypotenuses is the first contact sealing surface, the width of described contact sealing surface is 1/3rd of V-type adsorption tank opening width, and two hypotenuses of described V-type adsorption tank are the second contact sealing surface.The utility model symmetry on two working surfaces of O RunddichtringO is shaped with V-type adsorption tank, when giving the certain fastening force of sealing flange, gas in the V-type adsorption tank of both sides is discharged, seal ring will produce suction-operated two flanged surfaces are firmly attached together, thereby plays the effects such as sealing, dustproof, damping.
Description
Technical field
The utility model belongs to the Sealing manufacturing technology field between mechanical fitting, is specifically related to a kind of for the slim adsorption type seal ring without the sealing of groove flange face.
Background technique
In medium and small machinery, railway locomotive, transformer, automobile, petroleum pipeline etc. have the equipment manufacturing technology field of liquid or gas conveying, in order to make mechanical internal cavity sealing effect better, prevent that liquid or gas are to external leakage, usually between axially docking with mechanical fitting, mechanical fitting processes groove, then adopt homogenous material to seal, the processing precision direct influence of groove is to sealing effect, as rubber seal, metal o-ring, spring sealed circle etc.During special employing " O " RunddichtringO, larger connection power need to be between two connected components, applied and effective sealing could be realized, when the parts wall thickness that connects when needs is thinner, larger connection power can make connected element distortion cause seal failure, is therefore necessary to propose to improve.
Model utility content
The technical problem that the utility model solves: provide a kind of for the slim adsorption type seal ring without the sealing of groove flange face, on two working surfaces of O RunddichtringO, symmetry is shaped with V-type adsorption tank, when giving the certain fastening force of sealing flange, gas in the V-type adsorption tank of both sides is discharged, seal ring will produce suction-operated two flanged surfaces are firmly attached together, thereby plays the effects such as sealing, dustproof, damping.
The technical solution adopted in the utility model: for the slim adsorption type seal ring without the sealing of groove flange face, there is O RunddichtringO, on two working surfaces of described O RunddichtringO, symmetry is shaped with V-type adsorption tank, two hypotenuses of described V-type adsorption tank are 35 degree angles, the exterior edge face of described two hypotenuses is the first contact sealing surface, the width of described contact sealing surface is 1/3rd of V-type adsorption tank opening width, and two hypotenuses of described V-type adsorption tank are the second contact sealing surface.
Further, the degree of depth of described V-type adsorption tank and its hypotenuse are equal in length.
Further, described V-type adsorption tank bottom thickness is its groove depth 1/2nd.
The utility model advantage compared with prior art:
1, being applicable to the vessel flange face that fastening force is less seals, prevents dust;
2, be applicable to the poor flanged surface of rigidity or the sealing between object, dustproof;
3, be applicable to flanged surface or the sealing between object, dustproof that surface finishment is higher.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is used view before the utility model assembling;
Fig. 4 is used view after the utility model assembling.
Embodiment
Below in conjunction with accompanying drawing 1-4, a kind of embodiment of the present utility model is described.
For the slim adsorption type seal ring without the sealing of groove flange face, there is O RunddichtringO 1, on two working surfaces of described O RunddichtringO 1, symmetry is shaped with V-type adsorption tank 2, two hypotenuses of described V-type adsorption tank 2 are 35 degree angles, the exterior edge face of described two hypotenuses is the first contact sealing surface 3, the width of described contact sealing surface 3 is 1/3rd of V-type adsorption tank 2 opening width, and two hypotenuses of described V-type adsorption tank 2 are the second contact sealing surface 4; Described V-type adsorption tank 2 bottom thickness are its groove depth 1/2nd; The degree of depth of described V-type adsorption tank 2 and its hypotenuse are equal in length.Above-mentioned feature makes to give the fastening force that parts to be sealed are less just can be made well to seal between the two.
The utility model is shaped with V-type adsorption tank 2 at two working surfaces, between flange or two articles, the first contact sealing surface 3 first contacts with flange or two articles, when giving certain fastening force, gas in both sides V-type adsorption tank 2 is discharged, the second contact sealing surface 4 will produce suction-operated and flange or two articles and firmly fit together, thereby play the effects such as sealing, dustproof, damping, solved that the requirement of vessel flange face fastening force is low, highly polished or vessel rigidity is little and need sealing technical barrier.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
