The drainage pipeline is characterized in that the measures of diversion of rain and sewage are taken into consideration, namely, the rain water is generally discharged into a river nearby, and the sewage is discharged into a sewage treatment plant, so that the municipal drainage pipeline comprises two pipelines, namely the rain water and the sewage.

The municipal water supply and drainage pipeline system has higher requirements on the tightness of pipelines and pipe fittings, and if the pipeline system has leakage accidents during operation, the maintenance is time-consuming and labor-consuming, and the cost is higher. Therefore, the pipe system needs to be subjected to a pressing test after being installed, and some pipe fittings need to be subjected to a hydrostatic test before leaving the factory. In all test processes, a pressing connector connected with pressing equipment is needed.

In the past, most of the pressing connectors are steel-plastic conversion external thread connectors, before the pressing test, the plastic part of the steel-plastic conversion external thread connector and the end cap pipe fitting are subjected to hot-melt socket welding to form a whole, and then the end cap is welded on a pressing pipeline or pipe fitting for use.

In the process of designing the adapter, the inventor of the application finds that at least the following technical problems exist in the technology:

after the pressing experiment is finished, the end cap and the steel-plastic conversion external thread joint are scrapped at the same time, so that certain waste is caused; and the steel-plastic conversion external thread joint cannot bear too high experimental pressure due to the self structure, therefore, we propose a multifunctional joint for pressing a pipeline assembly to solve the problems.
