Novel seal components

Abstract

The invention provides a novel sealing element, in particular to the novel sealing element made of a bimetallic material with high-temperature resistance and high-pressure resistance. The appearance of the sealing element is of a hollow cylinder body, wherein the cylinder body is generally of a round shape or a square shape, and the hollow part is used for fluid passing through. The novel sealing element consists of at least two layers of different metals, and also can be combined of different metals with three layers or more than three layers. The novel sealing element solves the problem of difficult sealing in a high-temperature high-pressure environment, and makes up the defects in the prior art.

Description

technical field [0001] The invention relates to a new type of sealing part, in particular to a new type of sealing part of bimetallic material resistant to high temperature and high pressure. Background technique [0002] In the melt spinning equipment, the seal plays an important role in connection and sealing between the spinning box and the spinning assembly. [0003] At present, known seals can be divided into two categories, traditional seals composed of a single material, and composite seals composed of two or more materials. [0004] Seals composed of a single material can be mainly divided into three types: 1) organic material seals such as PTFE (polytetrafluoroethylene), FPM (fluororubber), etc. Limited capacity (generally lower than 40bar); 2) Inorganic material seals, such as graphite and asbestos, have limited deformation capacity, difficult molding, inaccurate dimensions, and instability; 3) Metal seals can withstand high temperatures, but sealing is difficult,...
