Example Embodiment

[0008] The present invention will be further described below in conjunction with the drawings and embodiments.

[0009] See figure 1 , A floating seal, comprising a sealing groove 1, a metal sealing ring 2 is arranged in the sealing groove 1, and an O-ring 3 is arranged inwardly of the metal sealing ring 2, and the sealing surface is held by the O-ring 3 4 Avoid draining the soil from the inside.

[0010] The beneficial effect of the present invention is that it can be applied to pipeline construction equipment, so that the soil will not be discharged from the inside to the outside into the device and affect normal operation. It can achieve radial end face sealing, with small friction, small contact area, and sealing. Good effect, long life and low price.

Abstract

The invention relates to a floating seal, which includes a sealing groove, and a metal sealing ring is arranged in the sealing groove, and an O-shaped sealing ring is arranged on the inner side of the metal sealing ring, and the O-shaped sealing ring withstands the sealing surface to prevent the inner soil from moving to the inside. Exhaust. It can be applied to pipeline construction equipment, so that the soil will not be discharged from the inside to the outside and enter the device to affect the normal work. It can realize radial end face sealing, with small friction, small contact area, good sealing effect, long life and low price. low-level features.

Description

technical field [0001] The invention belongs to the technical field of sealing structures and relates to a floating seal. Background technique [0002] The existing seals are all used to avoid sealing the outside to prevent dirt from entering the inside of the device, while the underground construction equipment for small-diameter pipelines works from the middle output shaft, so the soil is scattered from the inside to the outside. Therefore existing sealing all can't be applied to pipeline construction equipment. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a floating seal, which can be applied to pipeline construction equipment, so that the soil will not be discharged from the inside to the outside and enter the device to affect normal work, and it can realize radial end face sealing. It has the characteristics of small friction, small contact area, good sealing effect, long lif...
