The plug-in type quick-connection overflow valve is characterized in that the outer wall of the fixing seat is provided with a clamping rib, the inner wall of the main body is provided with a limiting groove, and the clamping rib is in limiting fit with the limiting groove, or the outer wall of the fixing seat is provided with a positioning groove, the inner wall of the main body is provided with a clamping rib, and the clamping rib is in limiting fit with the limiting groove.

The mounting ring under system have the mounting groove, set up sealed the pad in the mounting groove, perhaps system has the seal receptacle under the mounting ring, sealed pad cladding is at the seal receptacle outer wall.

The outer wall of the mounting ring is provided with an outer flow guide rib groove.

The upper end of the guide post is provided with a limit convex rib.

The inner wall of the fixed seat is provided with an inner flow guide rib groove.
