product description

The beneficial effects of the present utility model are:

1. A ring-shaped flexible sealing airbag is added on the outer ring of the flap valve, and the flexible sealing airbag is filled with inert gas. The flexible sealing airbag is more conducive to extrusion deformation, so that the flexible sealing airbag can be connected with the check valve body. The sealing surface is in closer contact to ensure the non-return sealing effect of the flap valve;

2. An auxiliary seal recovery mechanism is set on one side of the flap disc. When the liquid on the fluid input side decreases, the auxiliary recovery weight ball in the auxiliary seal recovery mechanism can accelerate the reset of the flap valve under the action of gravity to ensure the stop The back sealing action is reliable, and when the flap valve is opened, the auxiliary return weight ball will not interfere with the action of the flap valve, and will not affect the valve performance;

In a word, the flap valve flap of the utility model has a stable structure, is not easy to be aged and deformed, the flap flap valve flap has reliable check sealing operation, good check sealing effect, and can be used stably for a long time.
