Abstract

The invention discloses a combined sealing ring, which comprises a sealing ring body, a No. 1 groove is arranged on the inner wall of the sealing ring body, and a No. A No. 2 groove is provided, and a No. 2 O-ring is arranged in the No. 2 groove. The lower end of the sealing ring body is provided with a grease storage tank. Both the No. 1 groove and the No. 2 groove are connected with the grease storage tank. The invention has the advantages of simple structural design and long service life. Through the cooperation of the sealing ring body, the No. 1 O-ring and the No. 2 O-ring, the multi-layer sealing of the piston rod is realized, and the sealing quality of the piston rod is guaranteed. At the same time, a grease storage tank is provided on the sealing ring body, which facilitates the lubrication of the No. 1 O-ring and the No. 2 O-ring, and increases the service life of the sealing ring.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to a combined sealing ring. Background technique [0002] Rotary hydraulic rotation exists in various industrial fields such as construction machinery, construction machinery, and automotive equipment. It is used to seal rods, shafts, rotary joints, etc. that have rotating or swinging motions. It is a two-way rotating sealing ring that can withstand pressure on both sides or alternating pressure. At present, during the use of the sealing ring, the service life of the sealing ring is extremely short due to the harsh environment in which the sealing ring is used. Therefore, there is a need for a composite sealing ring with a long service life on the market. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is to propose a combined sealing ring. [0004] The present invention solve...
