Abstract

The invention relates to an elastic sealing ring and a circular-arc slide sealing device, and belongs to the technical field of fluid sealing. The elastic sealing ring comprises an elastic sealing ring body, a sealing slot, lubricating grease, a circular-arc surface fixing part, a circular-arc surface rotating part, a liquid flow hole I and a liquid flow hole II, wherein the elastic sealing ring is mounted in the sealing slot; the sealing slot is formed in the slide surface of the circular-arc surface rotating part; the lubricating grease is coated between the elastic sealing ring and the circular-arc surface fixing part; the circular-arc surface rotating part is assembled in the circular-arc surface fixing part and is in clearance fit with the circular-arc surface fixing part; and a sealing hole is circular. The sealing ring can realize three-stage sealing, is high in sealing pressure grade, and can be used for planar sealing or peripheral rotating sealing or reciprocating sealing.

Description

technical field [0001] The invention relates to an elastic sealing ring and an arc sliding sealing device, belonging to the technical field of fluid sealing. Background technique [0002] Sealing is a measure to prevent fluid or solid particulate media from leaking from adjacent joint surfaces in a machine (or equipment, device) and to prevent external impurities, such as dust, moisture, etc. from intruding into its interior. Poor sealing will reduce the efficiency of the machine (or equipment, device), cause waste and pollute the environment. Leakage is a phenomenon in which a small amount of fluid that does not perform useful work leaks out of the seal. [0003] In sealing, according to whether there is relative movement of the sealing coupling surface, it is divided into static sealing and dynamic sealing. In the dynamic sealing method and structure, it is mostly aimed at the sealing of the rotating pair and the reciprocating sliding pair, such as the shaft seal and the...
