Rotary sealing device

Abstract

The invention discloses a rotary sealing device which comprises a base. A rotating body is arranged at one end of the inner side of the base, a rotating piece and a fixing piece are arranged at the inner side of the rotating body, the rotating piece and the fixing piece are connected in a rotating manner, elastic rubber is arranged at one side of the rotating piece and one side of the fixing piece, and the elastic rubber is of an annular structure; and the elastic rubber is arranged in the inner side of the rotating body. According to the rotary sealing device, sealing is carried out in a screwing and extruding manner, sealing can be carried out within the deformation range of the elastic rubber and within the range that the internal diameter reaches zero, the sealing range is ultra-wide, and the sealing practicability is improved; when the device is used, the sealing structure can be pre-installed in advance, sealing can be carried out by screwing the rotating piece after a cable penetrates through the sealing structure, the installation time is saved, and the installing efficiency is improved; and meanwhile, the sealing structure is simple and convenient to install, later part replacement is facilitated, secondary construction is not needed, and the practicability of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of hole sealing, and in particular relates to a rotary sealing device. Background technique [0002] Seals can be divided into two categories: static seals and dynamic seals. Static seals mainly include gasket seals, sealant seals and direct contact seals. According to the working pressure, the static seal can be divided into medium and low pressure static seal and high pressure static seal. Medium and low pressure static seals are commonly used for gasket seals with softer materials and wider widths, while high-pressure static seals use metal gaskets with harder materials and narrower contact widths. Dynamic seals can be divided into two basic types: rotary seals and reciprocating seals. [0003] The existing rotary sealing device usually seals the cable hole. At present, the original sealing method is still used in the sealing field market. The pain point is that the cable cannot be sealed well, and it c...

Problems solved by technology

[0004] The purpose of the present invention is to provide a rotary sealing device to solve the existing rotary sealing device proposed in the above-mentioned background technology. Usually, when sealing the wire hole, the original sealing method is still used in the current sealing field market, and the pain point is that : The cable cannot be sealed well, and it cannot be operated in some scenes with limited construction space. After sealing, the equipment cannot be moved, and the later maintenance needs to be disassembled and then sealed, which causes a secondary waste of manpower and material resources and affects the practicality of the seal.
