Problems solved by technology

However, due to working in a high-pressure environment, the O-ring is subjected to a large extrusion force, which makes the sealing ring in a deformed state for a long time, and is prone to permanent deformation and loss of elasticity, resulting in seal failure.

Embodiment approach

[0021] Such as figure 1 and figure 2 As shown, as an embodiment of the present invention, the inner wall of the sealing ring 1 is provided with a water inlet hole 12 along the radial direction, and the water inlet hole 12 communicates with the circular reaction tank 11 inside the sealing ring 1, When the sealing ring 1 is installed, the ionic liquid is injected into the annular reaction tank 11 of the sealing ring 1 through the water inlet hole 12, and the ionic liquid entering the annular reaction tank 11 is used as the reaction medium to make the iron powder and carbon powder undergo micro-electrolysis reaction, Iron powder and carbon powder have a micro-electrolysis reaction to produce iron sludge and hydrogen gas, and the hydrogen gas is discharged through the water inlet hole 12, so that the iron sludge fills the circular reaction tank 11 of the sealing ring 1, which improves the rigidity of the sealing ring 1 and avoids sealing Excessive plastic deformation of the ring...

Abstract

The invention belongs to the technical field of seal parts and particularly provides an O-shaped seal ring. A circular-ring-shaped reaction groove is axially formed in the seal ring, the mixture of iron powder and carbon powder is put in the circular-ring-shaped reaction groove, the mass ratio of the iron powder to the carbon powder is 20-25 to 1, and the diameter of the iron powder is 10-20 microns. The rigidity of the seal ring can be improved, the size of the seal ring can be increased, and accordingly the sealing effect of the seal ring can be improved.

Description

technical field [0001] The invention belongs to the technical field of sealing elements, in particular to an O-shaped sealing ring. 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 takes a long time to arrive. During the mainte...
