Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to a metal gasket. Background Art

[0002] A metal gasket is a part used to seal the connection part to prevent fluid or gas leakage. It is usually made of various metal materials such as stainless steel, copper, aluminum, titanium, etc. Metal gaskets are widely used in many fields such as chemical industry, petroleum, machinery, aerospace, etc. There are various types of metal gaskets, and common ones include flat gaskets, serrated gaskets, elliptical gaskets, octagonal gaskets, etc. Its sealing performance depends on factors such as the material, structure, dimensional accuracy, surface roughness of the gasket, and the pre-tightening force during installation.

[0003] When the existing metal gasket is in use, due to the high hardness of the metal gasket, precise fitting cannot be guaranteed, which further reduces the sealing performance of the gasket, easily leads to insufficient gas or liquid sealing, and even causes the problem of gas-liquid leakage. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the existing technology that due to the high hardness of the metal gasket, precise fitting cannot be guaranteed, which further reduces the sealing performance of the gasket, easily leads to insufficient gas or liquid sealing, and even causes the problem of gas-liquid leakage, and a metal gasket is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a metal gasket, including a metal gasket, second sealing rings are installed on both the upper and lower surfaces of the metal gasket, an upper clamping ring is installed on the upper surface of the metal gasket, a lower clamping ring is installed on the lower surface of the metal gasket, an upper sealing ring is installed on the surface of the upper clamping ring, a plurality of buffer dampers are distributed inside the upper clamping ring, a buffer pad is installed at one end of the buffer damper, and a lower sealing ring is installed on the surface of the lower clamping ring.

[0006] Preferably, a plurality of heat dissipation grooves are opened on the outer side of the metal gasket, and heat dissipation fins are installed inside the heat dissipation grooves.

[0007] Preferably, springs are symmetrically installed inside the heat dissipation grooves, a limiting plate is installed at one end of the spring, and the side surface of the limiting plate is connected to the side surface of the heat dissipation fin.

[0008] Preferably, a plurality of convex points are distributed on the surface of the lower clamping ring.

[0010] Preferably, the inner diameter of the metal gasket is 40 mm.

[0011] Preferably, the outer diameter of the metal gasket is 45 mm.

[0012] Preferably, the thickness of the metal gasket is 4.5 mm.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, second sealing rings are installed on both the upper and lower surfaces of the metal gasket. Cooperating with the first sealing ring helps to ensure the sealing performance of the metal gasket, avoid liquid leakage, and thus prevent resource waste. An upper clamping ring is installed on the upper surface of the metal gasket, which facilitates the connection between the outer side of the bolt and the inner side of the upper clamping ring. The upper sealing ring helps to further provide a good sealing effect, thereby extending the service life of the metal gasket. A lower clamping ring is installed on the lower surface of the metal gasket. The multiple bumps distributed at the bottom of the lower clamping ring help to improve the tightness of the connection with the nut, and the lower sealing ring further provides an effective sealing effect.

[0015] 2. In the present utility model, by utilizing the elastic support of the spring, the limiting plate effectively limits the heat sink, which helps to ensure the stability of the heat sink. The heat sink helps to increase the heat dissipation area of the metal gasket, and thus helps to quickly dissipate the heat generated at the sealing part, reduce the temperature of the metal gasket, reduce deformation caused by high temperature, extend the service life of the metal gasket, and thus ensure a good heat dissipation effect and the normal use of the metal gasket.
