Abstract
The utility model belongs to the field of aviation and relates to a structure for sealing a gravity oil filler cap. The size of the structure for sealing the gravity filler cap is matched with that of the sealing part of the gravity filler cap and the structure; the lower part of the structure for sealing the gravity filler cap is provided with a sealing ring for sealing an oil tank, and a sealing ring structure which faces upward is extended outward from the upper part of the structure for sealing the gravity filler cap; and a downward bulge is formed on the outer edge of the sealing ring structure. The sealing ring can fill a gap between the gravity oil filler cap and a surrounding structure of an airplane, and the structure for sealing the gravity filler cap can be in tight fit with the surrounding structure by the extrusion deformation between the annular bulge and the surrounding structure to achieve the sealing effect, so that accumulated water at a gravity oil filler can be effectively prevented; and therefore, the erosion caused by the accumulated water or pollution caused when foreign matter enters the oil tank during opening of the gravity oil filler cap can be prevented.
Description
Technical field
The utility model belongs to aviation field, relates to a kind of gravity oiling flap sealing configuration.
Background technique
Aircraft gravity oiling flap generally adopts quick-disconnect to be mounted on the aircraft upper surface; Between gravity oiling flap and peripheral structure, have several mm clearance, very easily produce ponding and cause corrosion or when opening the gravity oiling flap, have foreign matter entering fuel tank to pollute.
Because aircraft gravity oiling flap needs open and close, is inconvenient to carry out traditional sealer encapsulation process.
The model utility content
The purpose of the utility model provides a kind of gravity oiling flap sealing configuration that can effectively prevent gravity fuel filler ponding of simple in structure, good seal performance.
The technical solution of the utility model: a kind of gravity oiling flap sealing configuration; Its size and gravity oiling flap and sealing structure partly are complementary; Sealing structure bottom is the seal ring that is used for the fuel tank sealing; Its top is outward extended with seal ring structure up, and sealing ring structure outer rim has downward convexity.
The seal ring that is used for the fuel tank sealing is the O RunddichtringO.
Convexity that sealing ring outer rim is downward and seal ring form 45 ° of angles.
Adopt special-shaped seal ring to realize the sealing of gravity oiling flap and fuel tank and the gap between filling gravity oiling flap and the peripheral structure, reach the purpose that prevents ponding.
Advantage of the utility model and beneficial effect: the utility model seal ring can be filled the gap between aircraft gravity oiling flap and the peripheral structure; And fit tightly with it through the extrusion-deformation between annular protrusion and peripheral structure; Reach seal action; Thereby prevent the ponding at gravity fuel filler place effectively, and then prevent that ponding from causing corrosion or when opening the gravity oiling flap, having foreign matter entering fuel tank to pollute.
Description of drawings
Fig. 1 is the plan view of the utility model gravity oiling flap sealing configuration;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the I portion enlarged view of Fig. 2;
Fig. 4 is the scheme of installation of the utility model gravity oiling flap sealing configuration,
Wherein, 1-gravity oiling flap, 2-gravity oiling flap sealing configuration, the 3-peripheral structure, the 4-O RunddichtringO, the 5-seal ring, 6-is protruding.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described further:
Please consult Fig. 1, Fig. 2 and Fig. 3 simultaneously, wherein, Fig. 1 is the plan view of the utility model gravity oiling flap sealing configuration, and Fig. 2 is the A-A sectional view of Fig. 1, and Fig. 3 is the partial enlarged drawing of Fig. 1.The utility model gravity oiling flap sealing configuration 2 is the seal ring that partly is complementary with gravity oiling flap seal groove, and sealing circle bottom is the O RunddichtringO 4 that is used for the fuel tank sealing, and this O RunddichtringO top is outward extended with seal ring 5 up.Sealing ring 5 outer rims have downward convexity 6; This annular protrusion and peripheral structure extrusion-deformation mutually; Can fit tightly, fill the gap between gravity oiling flap 1 and the peripheral structure 3, thereby prevent ponding effectively; And then prevent that ponding from causing corrosion or when opening the gravity oiling flap, having foreign matter entering fuel tank to pollute, as shown in Figure 4.
In this mode of execution, the maximal clearance between aircraft gravity oiling flap and the peripheral structure is 2.5mm, and sealing ring radial width is 2.6mm, axial thickness 2mm, and its outer rim has downward convexity and seal ring forms 45 ° of angles.
Claims (3)
1. gravity oiling flap sealing configuration; It is characterized in that: its size and gravity oiling flap and sealing structure partly are complementary; Sealing structure bottom is the seal ring that is used for the fuel tank sealing; Its top is outward extended with seal ring structure up, and sealing ring structure outer rim has downward convexity.
2. gravity oiling flap sealing configuration according to claim 1 is characterized in that: the seal ring that is used for the fuel tank sealing is the O RunddichtringO.
