Abstract
The utility model discloses a mica compound type winding sealing gasket, which comprises a body, wherein the body comprises a plurality of graphite layers, the inner ring of the body is provided with a plurality of mica layers, and the graphite layers are positioned on the outer ring of the body and surround the mica layers; the gasket has the advantages that the gasket with the structure keeps the compensation performance of graphite materials on the surface roughness of the flange, and the inner ring is reinforced by the mica materials which have extremely high temperature resistance, so that the direct impact of high-temperature gas of the flange pipe of the inner ring on the graphite is blocked, the integral temperature resistance of the gasket is improved, and the requirement of low leakage under the high-temperature condition can be met.
Description
Technical Field
The utility model relates to a sealed field especially relates to a compound winding of mica is sealed to be filled up.
Background
The sealing gasket used at the connecting part of the flange and the hot end flange of the exhaust system of the automobile has higher requirements on temperature resistance and sealing performance, and the conventional graphite material and the winding gasket of the stainless steel metal structure have limited temperature resistance, so that after long-term durable use, a certain amount of burning loss of graphite can obviously reduce the sealing performance and have leakage hidden trouble.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a compound winding of mica is sealed that high temperature resistant performance is good, and compensatory ability is strong is provided.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a compound winding of mica is sealed fills up, includes the body, the body includes a plurality of layers of graphite layer, the inner circle of body is provided with a plurality of layers of mica layer, the graphite layer is located the body outer lane and encircles the mica layer.
Compared with the improvement of the scheme, metal layers are arranged between the adjacent graphite layers, between the adjacent mica layers and between the graphite layers and the mica layers.
Compared with the improvement of the scheme, the mica layer and the graphite layer are respectively provided with two layers.
Compared with the improvement of the scheme, the innermost circle and the outermost circle of the body are both provided with metal layers.
Compared with the improvement of the scheme, the cross section of the metal layer is V-shaped or W-shaped.
Compared with the improvement of the scheme, the metal layer is made of stainless steel.
Compared with the prior art, the utility model has the advantages that, metallic stainless steel and graphite material and mica material winding combination, the product adopts the reinforcing of metallic stainless steel fixed in the inner circle, and the stainless steel of V-arrangement, W shape increases the resilience that seals up, then adopts the mica material winding in the inner circle, uses the winding of graphite material again in the outer lane, uses the reinforcing of metallic stainless steel fixed in the outermost circle, and the shape and the size of a dimension that the outer lane size was fit for the flange assembly in the product. The sealing gasket with the structure keeps the compensation performance of graphite materials on the surface roughness of the flange, and the inner ring is reinforced by the mica materials which have extremely high temperature resistance, so that the direct impact of high-temperature gas of the flange pipe of the inner ring on the graphite is blocked, the integral temperature resistance of the gasket is improved, and the low leakage requirement under the high-temperature condition can be met.

Fig. 2 is an enlarged view of fig. 1 at a.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
FIG. 1 is a mica composite type wound sealing gasket, wherein the innermost ring of the sealing gasket is reinforced and fixed by metal stainless steel, the V-shaped stainless steel and the W-shaped stainless steel are used for increasing the resilience of the sealing gasket, then the inner ring is wound by mica materials, and the mica layer 1 has two layers. And the outer ring is wound by using graphite materials, and the graphite layer 2 has two layers. And a metal layer 3 is arranged between the mica layer 1 and the graphite layer 2 and between the mica layer 1 and the graphite layer 2, so that the resilience of the gasket is enhanced. And the outermost ring is reinforced and fixed by using metal stainless steel, and the sizes of the inner ring and the outer ring of the product are suitable for the shape and size of flange assembly. The sealing gasket with the structure keeps the compensation performance of graphite materials on the surface roughness of the flange, and the inner ring is reinforced by the mica materials which have extremely high temperature resistance, so that the direct impact of high-temperature gas of the flange pipe of the inner ring on the graphite is blocked, the integral temperature resistance of the gasket is improved, and the low leakage requirement under the high-temperature condition can be met.
