Abstract
The utility model discloses a gland bush, which comprises an outer ring and an inner ring; wherein, the outer ring is a metal framework; the inner ring is a sealing rubber ring; and the metal framework is tightly jointed with the sealing rubber ring. By utilizing a sealing zone formed by the compressed sealing rubber ring and a sealed element, the purpose of sealing can be achieved. The gland bush is characterized by simple design, good sealing effect and easy installation.
Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to a kind of gasket seal of diesel low-voltage pipeline.
Background technique
At present, in the low pressure line of diesel engine, the gasket seal that end face seal structure connects generally adopts metallic packing, combined labyrinth and carbon gland pad or composite seal pad.Metallic packing does not possess the function that is repeatedly used, combined labyrinth and carbon gland pad and composite seal pad require very strict to the aperture chamfer machining of sealed part, be not suitable for the general processing technology of China at present, make the sealing material of pad often all be absorbed in the aperture chamfering of part to be processed, can not form sealing strip, cause the poorly sealed seepage that causes.Simultaneously, above-mentioned three kinds of standard pads all exist with a kind of principle hidden danger, the through-hole diameter that is pad is generally all than the about 0.2mm of hinge bolt nominal diameter, and this will will cause gasket seal not overlap with the hinge bolt center line in assembly process, thereby reduce seal band.For above-mentioned reasons, cause the diesel low-voltage line seal not tight, the seepage phenomenon takes place easily, influence quality, when serious even can influence the engine start performance.
The model utility content
At the deficiencies in the prior art, the utility model provides a kind of to be satisfied centralized positioning, increase seal band and meets the gasket seal that has the processes demand now.
The utility model provides a kind of gasket seal, and the sealing pad comprises outer ring and inner ring, and described outer ring is a metal frame, and described inner ring is a sealing rubber ring, described metal frame and described sealing rubber ring fluid-tight engagement.
In the utility model, described metal frame inboard has flange, is provided with the groove that holds described flange in the described sealing rubber ring outside, and described flange closely cooperates with described groove and connects.
In the utility model, described metal frame is whole punching press type.
In the utility model, the internal diameter of described sealing rubber ring is than the little 0～0.2mm of nominal diameter of sealing pad.
In the utility model, the external diameter of described sealing rubber ring is than the big 3～4mm of nominal diameter of sealing pad.
In the utility model, the monolateral of described sealing rubber ring exceeds 0.1～0.3mm than metal frame.
In the utility model, described sealing rubber ring is made by nitrile butadiene rubber or acrylate rubber.
Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect:
1, have simple in structure, easy to process;
2, sealing effect is better;
3, has the centralized positioning function, easily assembling.
Description of drawings
Fig. 1 is the schematic representation of the gasket seal of the utility model diesel low-voltage pipeline.
The 1-metal frame; The 2-sealing rubber ring; The 3-flange.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, the sealing pad comprises outer ring and inner ring, and described outer ring is a metal frame 1, and described inner ring is a sealing rubber ring 2, described metal frame 1 and described sealing rubber ring 2 fluid-tight engagement.Gasket seal utilizes metal frame 1 to bear the pressure of end face, utilizes sealing rubber ring 2 to be out of shape the purpose that reaches sealing with sealed formation seal band by compression.The inboard of metal frame 1 also has flange 3, is provided with the groove that holds described flange 3 in described sealing rubber ring 2 outsides, and it is tightr to make that the sealing rubber ring connects in metal frame, and the vulcanized quality of sealing rubber ring 2 is played the effect of enhancing.
In the present embodiment, the inside diameter D 1 of sealing rubber ring 2 makes sealing rubber ring more effectively hold whelk bolt (general whelk bolt excessively is all little by about 0～0.2 than nominal diameter because of thread crest shape influences its actual outside diameter) tightly than the little 0～0.2mm of nominal diameter of gasket seal.The outer diameter D 2 of sealing rubber ring 2 is than the big 3～4mm of nominal diameter of gasket seal, (general screw chamfering adopts several modes in the space that the screw chamfering that makes rubber fill sealed part more effectively stays, a kind of be the screw chamfering to Major Diam, another kind is 1～1.5mm * 30 °～45 °).
The utility model relates to the diesel engine gasket seal, utilizes metal frame to do the outer ring, and inner round portion adopts rubber material.Metal frame adopts steel material, has the rubber locating flange, be stamped to form through integral body, caulking gum in mould through the sulfuration aftershaping.The sealing pad has simplicity of design, good sealing effect, the easy characteristics of installation.In addition, as long as sealing rubber ring 2 does not have breakage, the sealing pad just can be reused.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
