Abstract
The utility model discloses a lip-shaped sealing ring which comprises a lip-shaped ring body. A metal elastic part is arranged in a groove between two lips of the lip-shaped ring body, a polyether-ether-ketone casing is arranged on the outer lateral wall of the lip-shaped ring body, an annular groove is arranged on the inner lateral wall of the lip-shaped ring body, and an O-shaped rubber ring is arranged in the annular groove. The lip-shaped sealing ring utilizes elastic force of the metal elastic part to provide sealing pressure so that the sealing pressure of the lip-shaped sealing ring is not influenced by working environments, abrasion of the sealing ring and aging of materials. Furthermore, the polyether-ether-ketone casing is arranged on the outer lateral wall of the lip-shaped ring body so that the lip-shaped sealing ring has good self-lubricating performance and weather resistance. Additionally, the O-shaped rubber ring is arranged to provide auxiliary sealing so that the using range of the lip-shaped sealing ring is widened, and service life of the lip-shaped sealing ring is prolonged.
Description
Technical field
The utility model relates to the Sealing that uses in a kind of machinery equipment, relates in particular to a kind of lip-type packing.
Background technique
Existing lip-type packing, its circle body cross section is a lip, and its upper and lower lip body is compressed on the sealing surface during use, and its sealing load is provided by lip body self elasticity and the pressure that is filled in the sealing medium in the groove between two lips.When this single lip-type packing is used in the high-pressure medium environment; Because the sealing load that sealed medium pressure produces is big; Thereby good seal performance; But when in the low pressure media environment, using, the sealing load that sealed medium pressure produces is little, and this moment, the main elasticity of lip body self material that relies on provided sealing load.Along with its wearing and tearing and material aging can make lip body elasticity assembly descend so that disappearance, thereby its sealing effect can not get guaranteeing.Therefore, this single lip-type packing is short sealing life, and is applicable to hyperbaric environment usually and is not suitable for environment under low pressure.
Summary of the invention
To the problem that above-mentioned existing technology exists, the utility model purpose is to provide a kind of long service life, not only has been applicable to the high-pressure work environment but also has been applicable to the lip-type packing of operating on low voltage environment.
The technological scheme of the utility model is: a kind of lip-type packing; Comprise the lip circle body; Be provided with metallic elastic spare in the groove between two lips of said lip circle body; The outer side wall of said lip circle body is provided with the polyether-ether-ketone shell, and the madial wall of said lip circle body has circular groove, is provided with O type rubber ring in the circular groove.
As preferably, said metallic elastic spare is established and is supportted the U type elastic spring that is connected between two lips by several adjacent rows and constitutes.
As preferably, said lip circle body is processed by teflon.
The beneficial effect of the utility model is: utilized the elastic force of metallic elastic spare that sealing load is provided; Guaranteed that its sealing load does not receive the wearing and tearing of working environment and seal ring and the aging influence of material; And the outer side wall of lip circle body is provided with the polyether-ether-ketone shell, and self-lubricating property, weatherability are good, and are provided with O type rubber ring as auxiliary seal; Thereby widened using scope, prolonged the working life of seal ring.
