Design of check valve

There are convex check loops around the ventilation holes of the support plate, and a circular protrusion on the inner side of the center of the rubber membrane. When the fine bubble diffuser stops. The membrane firmly covers the non-return loop under the action of its own rebound and water depth pressure. At the same time, the bumps on the film are caught in the plate's non-return loop. Effectively prevent mud water from flowing backwards.
