Abstract
The utility model belongs to the mechanical field and particularly relates to a sealing ring which can be used for structures of to-be-sealed maintenance port covers of liquid-gas related boxes (tanks) of airplanes, ships, vehicles, oil depots and the like. The sealing ring adopts an elliptic, round or long-circle-shaped structure; the cross section of the sealing ring is transversally U-shaped; and the working end 1 of the sealing ring is thicker than its installation end 2, and a plurality of bulges 3 are arranged at the bottom of the working end 1. The sealing ring is made of the composite material of nitrile -butadiene rubber NBR-18 and chloroprene rubber CR-120. The working end is thicker than the installation end and can bear a larger extruding force, in addition, the bulges are arranged at the bottom of the working end 1, so that the compression force is further reduced and the situations of poor sealing reliability caused by uneven compression can also be reduced, and the sealing reliability is greatly improved.
Description
Technical field
The utility model belongs to mechanical field, and a kind of specifically seal ring can be used in the structure of safeguarding flap of relevant case (jar) the needs sealing of liquid such as aircraft, boats and ships, vehicle, oil depot and gas.
Background technique
Existing seal ring adopts circle more, and section shape is horizontal U font, and working surface and stationary plane uniform thickness through the compression work face seal, need pressure big, and be poorly sealed; High temperature resistant, not low temperature resistant, low temperature resistant, non-refractory, water-fast not oil resistant, short shortcomings such as (3 years) of life-span.
Summary of the invention
The technical problem that the utility model will solve:
The utility model has overcome of the prior art poorly sealed, high temperature resistant, not low temperature resistant, low temperature resistant, non-refractory, and water-fast not oil resistant, the shortcoming that the life-span is short etc. provides a kind of seal ring of high temperature resistant, low temperature resistant, Waterproofing/oilproofing.
The technological scheme of the utility model:
This seal ring is adopted as the circular or oval type structure of ellipse, and said seal ring section shape is horizontal U font, and said seal ring working end 1 is thicker than mounting end 2.
Preferably, 1 bottom, working end is provided with some protruding 3.
Preferably, the section of the convexity 3 of 1 bottom, working end is del or circular arc.
Preferably, seal ring is the composite material of nitrile butadiene rubber NBR-18 and neoprene CR-120 blend, and sulfuration back outer surface is coated with fluorine.
The beneficial effect of the utility model:
On the one hand, working end 1 is thicker than mounting end, makes it can bear extruding force better; On the other hand; The bottom of working end 1 is provided with some protruding 3, has further reduced to compress that required power is big, the uneven situation that causes the sealing reliability difference of pressure, improves sealing reliability greatly; Adopt the composite material of nitrile butadiene rubber NBR-18 and neoprene CR-120 blend, sulfuration back outer surface is coated with fluorine, solution seal ring non-refractory, not low temperature resistant, the shortcoming of Waterproofing/oilproofing not; After the product sulfuration, surfaces coated fluorine coating improves the seal ring life-span greatly outside, and long service life improves the seal ring life-span greatly.

Fig. 4 the utility model sectional drawing.
Wherein, the 1-working end, the 2-mounting end, 3-is protruding.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 3, said Sealing is oval circular or oval type structure, and said seal ring section shape is horizontal U font, and is as shown in Figure 4, and said seal ring working end 1 is thicker than mounting end 2.
Preferably, 1 bottom, working end is provided with some protruding 3.The bottom of working end 1 is provided with some protruding 3, has further reduced to compress that required power is big, the uneven situation that causes the sealing reliability difference of pressure, improves sealing reliability greatly
Preferably, the section of the convexity 3 of 1 bottom, working end is del or circular arc.Protruding 3 section is set to inverted triangle or circular arc, is convenient to processing on the one hand, on the other hand, can play the effect of good minimizing impacting force, realizes sealing function better.
Preferably, seal ring is the composite material of nitrile butadiene rubber NBR-18 and neoprene CR-120 blend, and sulfuration back outer surface is coated with fluorine.Through sulfuration, surfaces coated fluorine coating improves the seal ring life-span greatly outside, and long service life improves the seal ring life-span greatly.
To sum up, the utility model is thicker than mounting end in working end 1 on the one hand, makes it can bear extruding force better; On the other hand, the bottom of working end 1 is provided with some protruding 3, has further reduced to compress that required power is big, the uneven situation that causes the sealing reliability difference of pressure; Adopt the composite material of nitrile butadiene rubber NBR-18 and neoprene CR-120 blend; Sulfuration back outer surface is coated with fluorine, solves seal ring non-refractory, not low temperature resistant, the shortcoming of Waterproofing/oilproofing not, improves the seal ring life-span greatly.
