Side opening flap valve with stable butt joint function

Abstract

The side opening flap valve with the stable butt joint function comprises a door frame and four door leaves, the door leaves are located at the top of the door frame, a limiting frame is arranged in an inner cavity of the door frame, supporting frames are fixedly connected to the two sides of the front side and the rear side of the door frame, and supporting plates are fixedly connected to the tops of the supporting frames. Through cooperative use of the door leaf, the limiting rod, the limiting hole, the movable groove and the positioning mechanism, when the door leaf is deformed or deviated after being used for a long time, the damaged door leaf is pulled downwards, the limiting rod leaves the limiting hole and an inner cavity of the movable groove, then a new door leaf is reset, and the door leaf drives the limiting rod to penetrate through the limiting hole to enter the inner cavity of the movable groove; and then the limiting rod is fixed through the positioning mechanism, replacement is completed, and the problems that most of existing side opening flap valves do not have the capacity of rapidly replacing the door leaf, and the sealing performance becomes poor due to the fact that the door leaf is prone to deformation or deviation after being used for a long time are solved.

Description

technical field [0001] The invention belongs to the technical field of side-opening flap doors, in particular to a side-opening flap door with a stable docking function. Background technique [0002] The flap door is installed at the tail end of the drainage pipe and has the function of preventing the backflow of external water. The side-opening flap door is a kind of flap door. The problem in the prior art is that most of the existing side-opening flap doors do not It has the ability to quickly disassemble and assemble the door leaf. When the door leaf is used for a long time, it is easy to deform or shift, resulting in poor sealing performance. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a side flap door with a stable docking function, which has the advantage of quick replacement of the door leaf, and solves the problem that most of the existing side flap doors do not have the ability to quickly repl...
