Abstract

The invention discloses an unbiased load gasket used for bolt fastening. The force arm gasket includes an upper end surface, a lower end surface and an outer circular surface. A through hole is provided in the middle of the upper end surface, the two sides of the lower end surface extend horizontally towards the middle direction, the end of the extension end is inclined upwards and connected with the bottom edge of the through hole, and the bottom of the extension end of the lower end surface is provided with knurling . The unbiased load gasket used for bolt fastening of the present invention reduces the possibility of flange leakage caused by the loose contact between the flange and the gasket, greatly improves the use effect of the gasket, and its application field has certain advantages. market space.

Description

technical field [0001] The invention relates to a washer, in particular to an unbiased load washer used for bolt fastening. Background technique [0002] At present, for petrochemical and other industries, in the process of production and processing, there are various toxic, harmful, flammable and explosive dangerous substances in equipment and pipelines. The connection inside the equipment, the connection between equipment, the equipment Most of the connection with the pipeline and the connection between the pipeline and the pipeline are completed by bolt fastening. Since the contact surface between each flange and the nut is different during the fastening process, the fastening effect is not ideal, which will cause the flange to have a risk of leakage, causing the diffusion of toxic and harmful substances, and there is also a hidden danger of explosion. Contents of the invention [0003] The object of the present invention aims at the fact that the flange in the prior a...
