Description

V-shaped sealing element

Technical Field

The utility model relates to a sealing member technical field specifically is a V type sealing member.

Background

The seal is a material or a part that prevents fluid or solid particles from leaking from between adjacent bonding surfaces and prevents foreign substances such as dust and moisture from intruding into parts inside the machine equipment. The storage room temperature of the sealing element is preferably below 30 ℃, so that the sealing element is prevented from high-temperature aging. Although the sealing element is small, the sealing element has the function of becoming a basic part and a fitting in the main national economy industries such as national defense, chemical engineering, petroleum, coal, transportation, mechanical manufacturing and the like, and plays a very important role in the development of the national economy. In recent years, with the rapid growth of economics, the seal manufacturing industry has kept a two-digit growth. The domestic sealing industry generally presents the development situation that the enterprise scale is smaller and the technical level is lower. From the economic type of an enterprise, the percentage of civil-camp enterprises and three-fund enterprises is over 95 percent, and the enterprise is the main economic type of the industry; meanwhile, enterprises are basically concentrated in east China, and the east China occupies a considerable share and has high market concentration in terms of the number of the enterprises, sales income and asset scale.

However, the existing sealing element only has one annular sealing ring, so that the sealing effect is poor, the stability is poor in working, and the phenomenon of play can occur; thus, the existing need is not met, for which we propose a V-seal.
