1.5 Inch Perforated Insulation Pins Self Locking Washers Flat Washer Round Galvanized Steel Plaster Washers for Wall and Ceiling

Product Description

Metal wrapped gasket is a widely used sealing gasket, which is a resilient gasket in semi metal sealing gaskets. It is made of V-shaped or W-shaped thin steel strips alternately wrapped with various fillers, and can withstand high temperature, high pressure, and adapt to temperature or vacuum conditions. By changing the material combination of the gasket, the chemical corrosion problem of various media on the gasket can be solved. Its structural density can be made according to different locking force requirements. To strengthen the main body and accurately position, the wrapped gasket is equipped with a metal inner reinforcement ring and an outer positioning ring. The compression degree is controlled by the inner and outer steel rings, and the surface accuracy of the flange sealing surface in contact with the gasket is not required to be high.

Operation Process

The working principle of self-locking washers can be simply summarized as "frictional resistance". When the threaded connection is subjected to external force, the self-locking washer will generate a reverse frictional force to prevent the thread from loosening. This friction force is determined by the special structure and material of the self-locking washer.

The structure of self-locking washers is usually composed of a metal ring and a layer of elastic material. Metal rings are usually made of stainless steel or copper, and their surfaces have some protruding tooth like structures. These tooth shaped structures can increase the friction between self-locking washers and threaded connections. Elastic materials are usually made of rubber or plastic, and their function is to increase the elasticity of self-locking washers, making them easier to fit tightly with threaded connections.

When the self-locking washer is installed at the threaded connection, its metal ring will generate friction with the threaded surface. This friction can prevent thread loosening. At the same time, the elastic material will also increase the elasticity of the self-locking washer, making it easier to tightly fit with the threaded connection. In this way, the self-locking washer can play a good role in preventing loosening.
