Problems solved by technology
[0002] During the working process of the seal ring, in addition to bearing the working temperature, pressure, corrosion and other factors, it also needs to bear a certain temperature caused by the friction of the end face of the friction pair of the seal ring, which intensifies the wear of the end face of the friction pair of the seal ring. Thus affecting the sealing effect and service life of the sealing ring
If the width of the end face of the friction pair of the seal ring is appropriately increased, although the strength of the end face of the friction pair of the seal ring can be increased and the wear can be alleviated, it will increase the specific pressure of the end face, and at the same time increase the friction resistance and friction heat; if the seal ring is properly reduced Although the width of the end face of the friction pair can reduce frictional resistance and reduce frictional heat, it will reduce the strength of the end face of the friction pair of the seal ring, aggravate wear, and affect the sealing effect and service life of the seal ring

Embodiment Construction
[0013] The present invention is described below in conjunction with accompanying drawing.
[0014] as attached figure 1 The shown seal ring of the present invention includes a seal ring body 1, and a plurality of flow grooves 2 are evenly opened on the friction pair end surface of the seal ring body 1; the flow grooves 2 and the seal ring body 1 The outer circumferential surface of the trough is connected; the launder 2 is semicircular. When the end surface of the friction pair of the seal ring body 1 reaches a certain temperature due to friction, the heat can be dissipated in time through the flow groove 2, which can reduce the wear degree of the end surface of the friction pair of the seal ring, thereby increasing the sealing effect of the seal ring and extending the life. The sealing ring has a long service life.
[0015] The aforesaid sealing ring of the present invention has the best effect when there are eight launders.
[0016] The above-mentioned embodiments are onl...

The invention discloses a sealing ring, which comprises a sealing ring body. Eight semicircular runners are uniformly arranged on friction pair end faces of the sealing ring body and are communicated with the outer circumferential surface of the sealing body, and the depth of each runner is one fifth of the thickness of the sealing ring body. When the friction pair end face of the sealing ring body is heated by friction, heat can be dissipated in time through the runners 2 so that abrasion degree of the friction pair end faces of the sealing ring can be reduced, and accordingly, the sealing effect of the sealing ring is improved and the service life thereof is prolonged.
Description
technical field [0001] The invention relates to a sealing ring, in particular to a sealing ring capable of reducing wear on the end face of a friction pair, with good sealing effect and long service life, and belongs to the technical field of sealing parts. Background technique [0002] During the working process of the seal ring, in addition to bearing the working temperature, pressure, corrosion and other factors, it also needs to bear a certain temperature caused by the friction of the end face of the friction pair of the seal ring, which intensifies the wear of the end face of the friction pair of the seal ring. Then it affects the sealing effect and service life of the sealing ring. If the width of the end face of the friction pair of the seal ring is appropriately increased, although the strength of the end face of the friction pair of the seal ring can be increased and the wear can be alleviated, it will increase the specific pressure of the end face, and at the same ...
