Examples

The utility model provides an improve aircraft nose of vulcanizing tube leakproofness, as shown in fig. 1-5, including aircraft nose body 1, outwards extend boss 2 by the open end of aircraft nose body 1, inlay the inside sealing washer group 3 that plays multilayer seal of boss 2, and with boss 2 through the bolt fastening, be used for the fixed annular briquetting 4 of sealing washer group 3 of extrusion, this sealing washer group 3 includes flat ring seal 31, conical ring seal 32 and sets up the V type ring seal 33 between flat ring seal 31 and conical ring seal 32, this V type ring seal 33 is provided with more than one, and the cooperation of overlapping each other.

In this scheme, sealing washer group 3 adopts multilayer structure, including flat bottom ring sealing washer 31, conical ring sealing washer 32 and V type ring sealing washer 33, and this kind of multilayer design can increase sealed effect, improves sealing performance.

Moreover, annular briquetting in this scheme passes through the bolt fastening on the boss for extrude fixed flat bottom ring sealing washer, conical ring sealing washer and V type ring sealing washer, wherein flat bottom ring sealing washer and V type ring sealing washer's crooked shape can laminate pipeline level boss inside better, improves sealing performance, thereby avoids the problem of gas leakage in the production process, ensures equipment normal operating.

The outward end of the boss 2 is provided with a seal ring caulking groove 21 for assembling the seal ring group 3.

In this solution, the outward end of the boss 2 is provided with a seal ring caulking groove 21 for assembling the seal ring group 3. The design has the advantages that the sealing ring group can be conveniently installed on the boss, the installation steps are simplified, and the installation efficiency is improved. The existence of the seal ring caulking groove 21 can ensure that the seal ring group 3 is correctly fixed on the convex seat during assembly, thereby avoiding the deviation or falling of the seal ring. Therefore, the normal operation of the sealing ring is effectively ensured, the sealing performance is improved, and the occurrence of gas leakage is prevented.

In this embodiment, the flat bottom ring seal 31, the conical ring seal 32 and the V-ring seal 33 are teflon seals.

The seal ring group 3 is formed by sequentially superposing a flat-bottom circular ring seal ring, three V-shaped circular ring seal rings 33 and a conical circular ring seal ring.

In this scheme, flat bottom ring sealing washer is the first layer of sealing washer group, and its smooth bottom can effectively be contacted with the junction site to provide stable sealed effect. Then, the V-shaped ring seal ring is arranged between the flat-bottom ring seal ring and the conical ring seal ring, and has good elasticity and deformability. The bending shape of the sealing device can adapt to the deformation of the pipeline, and a more reliable sealing effect is provided. Finally, the conical ring sealing ring is used as the last layer of sealing ring, so that the sealing effect can be further enhanced, the conical design of the conical ring sealing ring can generate larger sealing force under the action of pressure, the sealing ring group can be tightly attached to the connecting part, and leakage is avoided.
