Embodiment Construction

[0051] Such as figure 2 As shown, the present invention provides a seal 100, the seal 100 basically includes a ring-shaped elastic seal body 20, the seal body 20 includes a through hole 60, a sealing surface 101, an inner force-bearing surface 50, a shaft To the force surface 70.

[0052] Wherein, the through hole 60 runs through the sealing body 20 . The through hole 60 can be slidably connected with a through shaft, that is, the through shaft is sleeved in the through hole 60 to limit the overall movement direction of the sealing body 20 to the axial direction.

[0053] Wherein, the sealing surface 101 is formed on the axially extending outer surface 10 of the sealing body 20 .

[0054] Wherein, the inner force-bearing surface 50 is formed on the inner surface extending axially of the sealing body 20 and is close to the end of the sealing body 20, the inner force-bearing surface 50 is arranged around the through hole 60, so The inner force-receiving surface 50 shrinks gr...

Abstract

The invention relates to the sealing field, in particular to a sealing element and a compression packer with the sealing element. A sealing element, comprising a sealing body, the sealing body includes: a through hole penetrating through the sealing body; a sealing surface, formed on the outer surface; an inner force bearing surface, formed on the inner surface and close to the end of the sealing body, and the inner side is stressed The surface is arranged around the through hole, and the inner force-bearing surface shrinks gradually from outside to inside so that the inner force-bearing surface is in a shrinking shape as a whole; and the axial force-bearing surface is formed on the side wall; when the axial force-bearing surface is axially squeezed When the inner force-bearing surface is pressed outward, the outer surface protrudes radially to drive the sealing surface formed on the outer surface to protrude radially for sealing. According to the sealing element of the present invention, since the axial force-bearing surface and the inner force-bearing surface can be simultaneously squeezed and deformed, the deformation capacity of the sealing element is increased, and the problem that the sealing element cannot be sealed due to insufficient deformation is effectively prevented.

Description

technical field [0001] The invention relates to the sealing field, in particular to a sealing element and a compression packer with the sealing element. Background technique [0002] Sealing materials refer to materials that can withstand joint displacement to achieve airtight and watertight purposes and are embedded in building joints. Seal materials include metal materials (aluminum, lead, indium, stainless steel, etc.), non-metallic materials (rubber, plastic, ceramics, graphite, etc.), composite materials (such as rubber-asbestos board, airgel felt-polyurethane), but The most used is rubber-like elastomer material. [0003] When the seal needs to withstand a certain pressure to make it deform to seal, it is necessary to consider the deformation capacity of the seal itself. If the deformation is insufficient, it will not be able to perform the sealing function; if the deformation is too large, it may cause the seal to collapse due to crushing. failure, loss of resilienc...
