Problems solved by technology

[0003] The main technical problem to be solved by the present invention is to provide a high-sealing flange, which can increase the number of gaskets to three pieces for the shortcomings of single-piece gaskets, such as poor sealing performance, weak tension, concentrated pressure, and easy wear. The thread is connected, and the contact surface with the flange is a wave thread, which can enhance the sealing performance and tension of the gasket, and at the same time distribute the pressure evenly, so that the gasket for flange connection is not easy to be worn

Abstract

The invention discloses a high-leakproofness flange which comprises a gasket for connection of first high-pressure water pipe flanges, a gasket for connection of second high-pressure water pipe flanges, a gasket for connection of third high-pressure water pipe flanges, convex-side threads, concave-side threads and wavy threads. The gasket for connection of the first high-pressure water pipe flanges is arranged on the upper layer of the gasket for connection of the second high-pressure water pipe flanges. The gasket for connection of the third high-pressure water pipe flanges is arranged on the lower layer of the gasket for connection of the second high-pressure water pipe flanges. The convex-side threads are arranged on the surface of the gasket for connection of the first high-pressure water pipe flanges and the gasket for connection of the third high-pressure water pipe flanges. The concave-side threads are arranged on the surface of the gasket for connection of the second high-pressure water pipe flanges. The wavy threads are arranged on the faces, in contact with the flanges, of the gasket for connection of the first high-pressure water pipe flanges and the gasket for connection of the second high-pressure water pipe flanges. By means of the manner, the high-leakproofness flange can enhance the leakproofness of the gaskets and improve tension, pressure is evenly divided, and abrasion is not likely to happen.

Description

technical field [0001] The invention relates to the field of flange manufacturing, in particular to a flange with high sealing performance. Background technique [0002] Flanges are parts connected between pipes, and gaskets are used to increase the sealing between flanges. There are many types of gaskets for existing flanges, including full-plane gaskets, convex gaskets, concave-convex gaskets, and tongue-and-groove gaskets, but there are only single-piece gaskets, which have poor sealing performance and weak tension. Concentrated pressure, easy to wear. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a high-sealing flange, which can increase the number of gaskets to three pieces for the shortcomings of single-piece gaskets, such as poor sealing performance, weak tension, concentrated pressure, and easy wear. The thread is connected, and the contact surface with the flange is a wave thread, which can enha...
