Problems solved by technology

However, since the O-ring as the basic elastic carrier cannot avoid the Achilles heel of permanent deformation during use, the combined sealing ring developed on the basis of the O-ring also cannot maintain a good sealing effect for a long time
Therefore, the service life of hydraulic and pneumatic cylinders using this type of sealing technology is relatively short.

Abstract

The invention relates a combined seal ring for a hole. The combined seal ring comprises an elastic rubber ring with an arc-shaped upper part, a seal ring arranged on the elastic rubber ring, check rings arranged at two sides of the seal ring and guide rings, wherein the guide rings are connected with the check rings in a matching manner and are provided with grooves. According to the invention, the combined type seal ring is adopted, the limits of back pressure generation, inaccuracy in positioning, low working pressure and the like generated when two sides of the traditional one-way sealing are respectively provided with one piece are broken through, the seal effect of the combined seal ring is increased and the service life of the combined seal ring is prolonged.

Description

technical field [0001] The invention relates to the field of seals, in particular to a combined seal ring of a piston and a cylinder in hydraulic and pneumatic transmission. Background technique [0002] With the continuous development of the domestic economy and the continuous improvement of national living standards, the degree of industrial automation of many domestic industrial and mining enterprises has been further improved, and sealing products play an important role in industrial automation. The quality of sealing products depends on the fluid power transmission in industrial automation. plays a key role. Especially in the national major equipment related to the national economy and the people's livelihood, the stable performance, reliable quality and tolerance of various fluid media of sealing products are very important. At the same time, the use of seals imported from foreign developed countries in major domestic key equipment is not only expensive, but also take...
