Description

Technical Field

[0001] The utility model relates to the technical field of water pump pipeline installation, and more specifically to a water pump leakage-proof quick connection device. Background Art

[0002] A water pump is a machine that transports liquid or pressurizes liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid. In the daily use of water pumps, pipes are installed at the liquid inlet and outlet of the water pump. The pipes are usually connected through flanges, and rubber rings are added between the flanges to ensure leakage during water pump transportation.

[0003] When installing the existing pipe flange, the bolts are passed through the connecting holes between the two flanges and then the bolts are fixed to complete the flange installation. However, there is no connection between the two flanges. When installing the bolts, the staff is required to stabilize the flange on the pipe and align the connecting holes on the two flanges to facilitate the installation of the bolts. At this time, multiple staff members are required to cooperate in the installation, which is inconvenient. Therefore, we propose a water pump anti-leakage quick connection device.
