Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-3, the seal ring for improving the bolt sealing in this embodiment includes a seal ring body 2, an upper grinding pad 1, a lower grinding pad 6 and a seal ring edge 3, the upper grinding pad 1 is fixed on the periphery of the upper end of the seal ring body 2 by means of clamping and pressing, the lower grinding pad 6 is arranged on the periphery of the bottom end of the seal ring body 2, clamping and fixing grooves 5 are formed on the seal ring body 2 near the upper grinding pad 1 and the lower grinding pad 6, a through hole 4 is formed in the middle of the seal ring body 2, a seal ring edge 3 is formed on the periphery of the bottom end of the seal ring body 2 near the through hole 4, a seal groove 7 is formed on the periphery side wall of the seal ring edge 3, and by the design of the upper grinding pad 1, the lower grinding pad 6, the seal ring edge 3, the clamping and the seal groove 5 and the seal groove 7, the sealing performance between the seal ring body 2 and the bolt and, the sealing performance of the sealing ring is better, the wear resistance of the sealing ring body 2 is improved, the service life of the sealing ring is prolonged, and the practicability is good.
As shown in fig. 1-3, in this embodiment, the bottom end of the upper grinding pad 1 adopts a wedge-shaped annular structure, the upper end of the lower grinding pad 6 adopts a wedge-shaped annular structure, the clamping groove 5 adopts a wedge-shaped annular structure, the size of the clamping groove 5 matches with the sizes of the upper grinding pad 1 and the lower grinding pad 6, so that the sealing ring body 2 is pressed by pressing the upper grinding pad 1 and the lower grinding pad 6 into the clamping groove 5, and the sealing ring body 2 is more tightly attached to the bolt, the sealing ring edge 3 adopts a cone-shaped annular structure, the maximum inner diameter of the sealing ring edge 3 is the same as the diameter of the through hole 4, so as to ensure that the diameter of the bolt rod is between the minimum inner diameter of the sealing ring edge 3 and the diameter of the through hole 4, and further facilitate the bottom end of the sealing ring edge 3 to be screwed with the bolt, the gap between the bolt and the upper end of the screw hole on the connecting piece is filled and, the upper grinding pad 1 and the lower grinding pad 6 are made of wear-resistant iron sheets, so that the wear resistance of the upper grinding pad 1 and the lower grinding pad 6 can be ensured.
