Dynamic sealing structure with pressure detection function

Abstract

The invention discloses a dynamic sealing structure with a pressure detection function, and the structure comprises a sealing seat, a sealing cover, a pressure detection device, and a rotating shaft.The sealing seat is a U-shaped sealing seat, and the external surface of the sealing seat is provided with a threaded fixing hole through welding. The sealing cover is connected with the threaded fixing hole welded on the external surface of the sealing seat through a locking bolt. The sealing cover comprises a longitudinal rod and a lateral rod cooperating with the sealing seat, wherein the longitudinal rod is welded at one end of the lateral rod to form a T-shaped integrated structure. The other end of the lateral rod extends to the interior of the cavity of the sealing seat. The rotating shaft sequentially passes through the longitudinal rod, the lateral rod and the sealing seat and then extends to the outside of the sealing seat. According to the invention, one end, far from the longitudinal rod, of the lateral rod is provided with the pressure detection device, thereby effectively preventing the excessive internal pressure of the sealing seat from causing damages to the sealing seat, and prolonging the service life of the structure.

Description

technical field [0001] The invention relates to the technical field of sealing structures, in particular to a dynamic sealing structure with a pressure detection function. Background technique [0002] In many manufacturing industries, sealing performance, as an extremely important characteristic, directly determines the quality of equipment technology. As we all know, the seals of the more common mechanical equipment are usually static seals, which are used to ensure the tightness between two relatively static parts, and the static seal technology has been relatively mature. [0003] At present, for many equipment that needs to move in the production process, it is often necessary to ensure the sealing between two relatively moving parts in the equipment. This type of equipment needs to be sealed by packing, and the existing dynamic sealing structure does not have a pressure detection function. During the packing process, the pressure in the sealing seat may increase due t...

AI Technical Summary

Problems solved by technology

This type of equipment needs to be sealed by packing, and the existing dynamic sealing structure does not have a pressure detection function. During the packing process, the pressure in the sealing seat may increase due to excessive packing and cause damage to the sealing seat, shortening The service life of the dynamic seal structure is reduced; the use is limited
