Description

Fastening type sealing ring

Technical Field

The utility model belongs to the technical field of pipeline connection, and particularly relates to a buckling type sealing ring.

Background

The sealing ring is mainly used for preventing leakage of gas and liquid, and the sealing ring used in industry is mainly a rubber or metal sealing ring. Most of the sealing rings used at present are closed annular structures, such as O-shaped rubber sealing rings, and the cross sections of the sealing rings can be round, oval or rectangular. The O-shaped sealing ring is widely applied due to the simple structure and low cost, but due to the closed annular structure, the equipment is almost completely disassembled in the process of installation or replacement, and all parts are required to be reinstalled after the sealing ring is installed or replaced, so that time and labor are wasted, and the service efficiency of the equipment is affected. For example, a double-wall corrugated pipe with a socket connection is required to be sleeved with a sealing ring in a trough of the outer wall of a pipe socket in advance, and then the socket is pulled into a socket of the pipe by adopting a special tool. The sealing rings are sleeved in the trough of the outer wall of the pipe socket in advance by manual work, so that the time and the labor are wasted for pipes with DN315 or more, the sealing rings are not easy to sleeve, and the construction progress is seriously affected.

Therefore, as a sealing ring disclosed in the patent with publication number CN101956826A, the sealing ring with the open-loop structure is bonded into an annular structure by adopting a bonding technology during installation or replacement, so that almost all equipment is not required to be disassembled, and the workload is greatly reduced. The sealing ring is arranged to be of an open-loop structure and then is arranged on the socket through detachable connection, although the installation process is simple and convenient, in the practical use of the sealing ring such as a corrugated pipe, the sealing ring is detachably connected and then is arranged on the socket, the socket is inserted into the bell mouth, in the insertion process, the sealing ring needs to generate friction with the inner wall of the bell mouth with larger positive pressure, the detachable mouth is easily damaged, and then the installation and sealing effect of the sealing ring are affected.
