Description
Technical Field
The utility model relates to a flange joint seals the field, especially relates to a metal winding piece.
Background
The metal wound gasket is a combined flat gasket formed by alternately winding a formed steel strip with a certain geometric section (such as a V shape or a W shape) and a non-metal strip. The inner side and the outer side of the metal winding gasket are both composed of a plurality of circles of steel belts, and the winding gasket is formed into a whole by butt welding the starting end of the inner steel belt and the tail end of the outer steel belt. The metal winding gasket makes full use of the heat resistance and compression resilience of the formed steel strip, and has excellent sealing performance of the non-metal filling strip through the combination of the formed steel strip and the non-metal strip. Metal wound gaskets are generally available, particularly for flange seals under conditions of stress relaxation, temperature and pressure fluctuations, shock and vibration. The utility model provides a novel metal winding piece, the structure is optimized more, and impact resistance, leakproofness and reliability further strengthen.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a metal winding piece, the structure is optimized more, and impact resistance, leakproofness and reliability further strengthen, the utility model discloses a following technical scheme:
the utility model relates to a metal winding piece, including holding ring, inner support ring and outer support ring, be provided with first sealing layer between inner support ring and the holding ring, be provided with the second sealing layer between outer support ring and the holding ring, first sealing layer and second sealing layer include the strap and the packing material area that a plurality of layers twine in turn and set up.
Furthermore, grooves are formed in the upper surface and the lower surface of the positioning ring, and rubber sealing rings are arranged in the grooves.
Further, the metal belt comprises a V-shaped support, an upper straight section and a lower straight section, the opening angle of the V-shaped support is 60 degrees, and the upper straight section and the lower straight section both slightly exceed the upper surface and the lower surface of the inner support ring and the outer support ring.
Further, the filling material belt is specifically a graphite sealing layer, a polytetrafluoroethylene or ceramic fiber sealing layer.
Further, the V-shaped support openings on the metal strips in the first sealing layer and the second sealing layer face opposite directions.
Furthermore, the metal strips are arranged on two sides of any filling material belt.
Compared with the prior art, the utility model discloses a beneficial technological effect:
the metal winding sheet of the utility model is provided with the first sealing layer and the second sealing layer which are independent of each other, and the first sealing layer and the second sealing layer act independently, and after one sealing layer is damaged by impact load, the other sealing layer can still ensure the original function of the metal winding sheet; in the utility model, the V-shaped support openings in the metal belts in the first sealing layer and the second sealing layer are opposite in direction, so that the first sealing layer and the second sealing layer have different stress structures, thereby improving the possibility that at least one sealing layer survives when the utility model is subjected to single-direction impact load; the utility model discloses and through setting up independent rubber seal, further improved the leakproofness. The utility model discloses rational in infrastructure, the leakproofness is good, and shock resistance is good, the good reliability.
Drawings
The invention will be further explained with reference to the following description of the drawings:
FIG. 1 is a front view of a metal winding sheet according to the present invention;
fig. 2 is a sectional view of the metal-wound sheet of the present invention taken along line a-a.
Description of reference numerals: 1. a positioning ring; 2. an inner support ring; 3. an outer support ring; 4. a first sealing layer; 5. a second sealing layer; 6. a metal strip; 7. filling the material belt; 8. a groove; 9. a rubber seal ring; 10. a V-shaped bracket; 11. an upper straight section; 12. a lower straight section.
Detailed Description
As shown in fig. 1 and 2, the metal winding sheet comprises a positioning ring 1, an inner support ring 2 and an outer support ring 3, wherein a first sealing layer 4 is embedded between the inner support ring 2 and the positioning ring 1, a second sealing layer 5 is embedded between the outer support ring 3 and the positioning ring 1, and the first sealing layer 4 and the second sealing layer 5 comprise a plurality of layers of metal strips 6 and filling material strips 7 which are alternately wound. The metal belt 6 is arranged on both sides of any filling material belt 7.
As shown in fig. 2, grooves 8 are formed in the upper surface and the lower surface of the positioning ring 1, rubber sealing rings 9 are arranged in the grooves 8, and the independent rubber sealing rings 9 are arranged to cooperate with the first sealing layer 4 and the second sealing layer 5, so that the sealing effect is better; the rubber seal 9 can maintain a certain sealing property even if both the first seal layer 4 and the second seal layer 5 break when subjected to an impact load.
The metal belt 6 comprises a V-shaped bracket 10, an upper straight section 11 and a lower straight section 12, the opening angle of the V-shaped bracket 10 is 60 degrees, and the upper straight section 11 and the lower straight section 12 both slightly exceed the upper surface and the lower surface of the inner support ring 2 and the outer support ring 3. Under the compression action of the flange walls on the two sides, the V-shaped bracket 10 has certain bending resistance and resilience, the metal belt 6 is matched with the filling material belt 7 to rebound, and the sealing performance is further enhanced.
The filling material belt 7 is specifically a graphite sealing layer, a polytetrafluoroethylene or ceramic fiber sealing layer.
