technical field

The utility model relates to a municipal pipeline connection facility, in particular to a municipal pipeline connection device.

Background technique

When underground water pipes or underground liquefaction pipes are connected, how to seal the pipes more tightly to prevent water leakage and air leakage has always been a long-standing problem. At the same time, if a certain pipe leaks water and air, it must be accurately It often takes a long time and effort to find the leak point, and if it is not dealt with in time, it may lead to safety accidents. Therefore, the pipeline connection device is an important component connecting pipelines and requires great attention. It can not only better avoid the occurrence of safety accidents, but also better extend the service life.
