Abstract
The utility model provides a sealing washer. The sealing washer comprises a washer body and an annular bulged groove arranged on the washer body. The sealing washer is provided with a through abut connection hole, and the bulged groove and the abut connection hole are coaxial. According to the sealing washer, the annular bulged groove is tightly attached to the contact surfaces of pieces to be sealed when stressed to deform, and an annular sealed space is formed. The contact method between the pieces to be sealed and the sealing washer is line contact, and therefore the sealing washer is tightly compressed with little installation moment of force, good sealing effect is achieved. The sealing washer is simple in structure and reliable in sealing.
Description
Technical field
The utility model relates to the field of sealing technology of aeroengine pipe joint, especially, relates to a kind of seal washer.
Background technique
Existing aeroengine pipe seal packing ring has two kinds usually, and a kind of is the sealing plain washer of non-metal rubber material preparation, and nonmetal rubber material elastic performance is good, but the rubber product shelf-life is short, and non-refractory is easily aging, fragile, every assembling once must more renew part; Another kind is the sealing plain washer of aluminum metallic material preparation, the plane of aluminum metal plain washer is squeezed easily to produce to be out of shape and realizes sealing, it is better than rubber seal plain washer temperature tolerance, but often need add very large mounting torque during assembling and could realize sealing, the plane rear difficult resilience that is squeezed, the sealing effect forfeiture is fast, and poor durability is fragile.
The model utility content
The utility model purpose is to provide a kind of novel seal washer, the easy technical problem that lost efficacy of sealing that causes because of poor heat resistance, poor durability and easy aged deterioration etc. to solve existing sealing plain washer.
For achieving the above object, provide a kind of seal washer according to the utility model, comprised packing ring body and the tongue that is arranged at the annular on the packing ring body; And seal washer is provided with the butt hole of perforation, tongue and butt hole coaxial line.
Further, the packing ring body comprises the body first surface and second of the body that be oppositely arranged with the body first surface, the direction projection that tongue is second to the body first surface to body.
Further, tongue is the V-type groove.
Further, seal washer is the seal washer of stainless steel material preparation.
Further, seal washer is the seal washer of 1Cr18Ni9Ti stainless steel material preparation.
Further, the surface of second of body first surface and body is provided with coating layer.
Further, the surface of second of body first surface and body is provided with silver-plated coating layer.
Further, seal washer is provided with the mounting hole of a plurality of perforations.
The utlity model has following beneficial effect: seal washer of the present utility model, its annular tongue when compressive deformation and to be sealed surface of contact fit tightly, formed the annular seal space, and to be sealed is the line contact when contacting with seal washer, so just seal washer of the present utility model can be compressed with less mounting torque, thereby play good sealing effect, this is simple in structure, and sealing is reliable.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the gasket structure schematic representation of the utility model preferred embodiment; And
Fig. 2 is the cross-sectional schematic of A-A of Fig. 1 of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1, the utility model provides a kind of seal washer, this seal washer is arranged at two to be sealed joints, this seal washer comprises packing ring body 1, is arranged at the tongue 2 of the annular on the packing ring body 1 and the butt hole 30 that connects, wherein, butt hole 30 and tongue 2 coaxial lines, butt hole 30 all is communicated with two to be sealed endoporus.
In conjunction with Fig. 2, packing ring body 1 comprises body first surface 11 and second 12 of the body that be oppositely arranged with body first surface 11, the direction projection that tongue 2 is second 12 to body first surface 11 to body, and then form projection on the surface of second 12 of body, form the groove that the projection with second 12 of body adapts on the surface of body first surface 11.Preferably, tongue 2 is the V-type groove, convenient preparation.
For easy for installation, seal washer of the present utility model also is provided with the mounting hole 31 of a plurality of perforations, is used for being fixedly connected with two to be sealed.
During seal washer work, second 12 while of body first surface 11 and body pressurized, at this moment, the annular tongue 2 of projection is compressive deformation at first, fit tightly with to be sealed surface of contact, formed the annular seal space, and to be sealed is the line contact when contacting with seal washer, so just seal washer of the present utility model can be compressed with less mounting torque, thereby play good sealing effect.
Preferably, seal washer of the present utility model is shaped with the stainless steel metal slice stamping, and Stainless Steel Products is high temperature resistant, is difficult for aging and damage; More preferably, seal washer adopts the preparation of 1Cr18Ni9Ti stainless steel material.
Preferably, be second 12 of the body first surface 11 that prevents seal washer and the body coating surface bonding with to be sealed, be provided with coating layer on the surface of second 12 of body first surface 11 and body; More preferably, this coating layer is silver-plated coating layer, can improve antiseptic property, guarantee good contact and sealing reliability.
Seal washer of the present utility model, its annular tongue 2 when compressive deformation and to be sealed surface of contact fit tightly, formed the annular seal space, and to be sealed is the line contact when contacting with seal washer, so just seal washer of the present utility model can be compressed with less mounting torque, thereby play good sealing effect, this is simple in structure, and sealing is reliable.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
