Abstract

The invention relates to a sealing device with an automatic compensation function, and belongs to the technical field of sealing. The sealing device comprises a flexible sealing body for sealing and apressure regulation part, wherein a pressure regulation cavity is formed in the flexible sealing body, and the pressure regulation part communicates with the pressure regulation cavity and is used for regulating the pressure in the pressure regulation cavity. The provided sealing device is simple and compact in structure and can not only automatically compensate for the sealing pressure, but alsoautomatically compensate for the sealing clearance, thereby being capable of effectively solving the problems of the prior art, being beneficial to prolonging the sealing life and achieving a bettersealing effect; and besides, the sealing device can regulate the sealing pressure in the use process to improve the sealing effect or meet the requirement for different sealing pressures, and is especially suitable for sealing fluid materials.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a sealing device with an automatic compensation function. Background technique [0002] In the process of various industries such as chemical industry, energy, pharmaceuticals, etc., there is a wide range of sealing requirements. In the prior art, sealing rings are usually used for sealing. There are many types of sealing rings, such as O-shaped sealing rings, rectangular sealing rings, U Type rings, V-type sealing rings, etc., can meet the needs of different occasions. [0003] However, due to factors such as the error of the production process and the matching degree of the assembly space of the existing sealing rings, there is usually a gap between the sealing ring and the surface to be sealed, which affects the sealing effect, and after a period of use, usually due to the sealing The wear and deformation of the ring lead to the gradual failure of the seal, which needs to be ...
