Pipeline connecting structure for municipal water supply and drainage

Abstract

The invention relates to the field of municipal engineering facilities, in particular to a pipeline connecting structure for municipal water supply and drainage. The pipeline connecting structure comprises a first connecting seat fixedly connected to a first pipeline and a second connecting seat fixedly connected to a second pipeline; a first insertion pipe communicating with the first pipeline is fixedly connected to the first connecting seat; a second insertion pipe communicating with the second pipeline is fixedly connected to the second connecting seat; an annular insertion groove is formed in the end face of a pipe opening of the first insertion pipe, and the second insertion pipe is in sliding inserted connection with the annular insertion groove; the second insertion pipe is provided with a filling device for filling a gap between the second insertion pipe and the inner groove wall of the annular insertion groove; and the first connecting seat and the second connecting seat are provided with fixing devices used for connecting and fixing the first connecting seat and the second connecting seat. The pipeline connecting structure has the effects that the pipeline repair and maintenance frequency caused by bolt corrosion can be reduced, and manpower and energy consumption is reduced.

Description

technical field [0001] The present application relates to the field of municipal engineering facilities, in particular to a pipe connection structure for municipal water supply and drainage. Background technique [0002] In my country, municipal facilities refer to various buildings, structures and equipment that are set up within the planning and construction scope of urban districts and towns to provide residents with paid or unpaid public products and services based on government responsibilities and obligations, and various public facilities supporting urban life. Infrastructure construction belongs to the category of municipal engineering, such as common urban roads, bridges and subways, such as various pipelines closely related to life. [0003] refer to figure 1 , in the related art, the connection mode of the municipal sewage pipeline is usually that a flange 32 is respectively arranged at the ends of the two sections of the pipeline. There is a rubber ring 33. Afte...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that pipeline one and pipeline two are only fixed by bolts, and the connection structure between pipeline one and pipeline two is single. Accelerate the corrosion rate of the bolts. After the bolts are continuously corroded, with the continuous flow of water in the pipes, a force will be generated to promote the relative movement of the connection between the two pipes. The fastening ability of the bolts will decrease due to corrosion. The bonding degree of the flange will be reduced, which will reduce the sealing performance of the pipeline connection and affect the sealing performance of the pipeline connection, thus increasing the frequency of pipeline repair and maintenance, which will increase the consumption of manpower and energy
