Wave spring applied to ultra-long sealing strip

Abstract

The invention relates to a wave spring applied to a super-long sealing strip, which comprises a mounting strip, a plurality of groups of abutting pieces are arranged on the mounting strip, and the plurality of groups of abutting pieces are used for abutting each position of the sealing strip against a special-shaped sealed device and fixing two ends of the mounting strip together when the sealed device is sleeved with the mounting strip. According to the sealing strip provided by the invention, the mounting strip is arranged on the sealed equipment in a sleeving manner, and at the moment, each position of the sealing strip can be propped against the special-shaped sealed equipment by the multiple groups of propping pieces, so that the contact effect between each position of the sealing strip and the sealed equipment is improved, and the sealing effect between the sealing strip and the special-shaped sealed equipment is improved.

Description

technical field [0001] The present application relates to the sealing field, in particular to a wave spring applied to an ultra-long sealing strip. Background technique [0002] As a common mechanical part, the sealing ring is widely used in all walks of life. It is often used in the dynamic sealing between the shaft and the hole, mainly to prevent liquid or gas leakage. Most of the sealing rings produced in the prior art are sealed by the elastomer body, and the sealing force is mainly provided by the system itself and the elasticity of the lip body of the sealing ring itself. In addition, there are some non-elastic sealing strips. When this kind of sealing strip is used, it usually needs to set a ring of elastic elements on the outer ring of the sealing strip. The elastic elements can tighten the sealing strip on the equipment to be sealed, so that the sealing strip follows the The thermal expansion and contraction of the sealing equipment expand and contract. When the se...

Problems solved by technology

In addition, there are some non-elastic sealing strips. When this kind of sealing strip is used, it usually needs to set a ring of elastic elements on the outer ring of the sealing strip. The elastic elements can tighten the sealing strip on the equipment to be sealed, so that the sealing strip follows the The thermal expansion and contraction of the sealing equipment expand and contract. When the sealed equipment is circular, the circular sealed equipment can drive the elastic ring to expand and contract as a whole. Consistent, but when the sealed equipment of the equipment is a special shape such as a square sealed equipment, the elastic ring will cause the four corners of the elastic ring to contact with the four corners of the square sealed equipment when it stretches, but the four sides of the elastic ring and the square The contact force between the four faces of the sealed equipment is small, which reduces the sealing effect between the sealing strip and the square sealed equipment
