Problems solved by technology

[0003] At present, the flap door equipped with the traditional large-scale flow channel is basically a whole flap door. Its volume and weight are huge, it is not easy to open the flap door (especially when the water output is small), and it consumes a lot of energy; when it is closed, Due to the effect of gravity, when the flap door is closed downward, the force is relatively large, which greatly damages the flow channel.

Embodiment Construction

[0050] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0051] like Figure 1 to Figure 11 As shown, an energy-saving three-page flap door includes: a rectangular parallelepiped large-scale flow channel 1, a middle flap door 3 located at the center of the end surface of the flow channel, side flap doors 2 located on both sides of the flow channel, and electromagnetic valves arranged on the side flap doors. Iron one 21, the water-stop rubber 22 between the side flap door and the end face of the exit, the iron bar 23 arranged on the upper and lower sides of the side flap door, the magnet one 31 arranged on the middle flap door, between the middle flap door and the side flap door Waterstop rubber 32, hinge device one 4, rotating rod 41, center fixed ring 42, rubber gasket layer 5, magnet two 6 embedded in the rubber gasket layer, hinge device two 7, rod cap 71, center fixing Rod 72, rotating circle 73, connecti...

Abstract

The invention discloses an energy-saving three-page flap door and its operation method. The flap door is composed of a middle flap door and side flap doors on both sides of the middle flap door. The side is hinged, and the top of the middle flap door is hinged at the top position of the outlet of the water outlet channel. When there is less water coming from the large runner, the middle flap door will be opened, and the two side flap doors will not be opened; when there is more water coming from the large runner, the middle flap door and the two side flap doors will be opened simultaneously. The invention realizes the opening and closing of the flap door through the cooperation of the electromagnet and the magnet, provides a certain buffer force when the middle flap door and the side flap door are opened and closed, and avoids the opening and closing of the middle flap door and the two side flap doors when the flap door is opened. collision, prolong the service life of the valve.

Description

technical field [0001] The invention belongs to the technical field of water pump station engineering, and in particular relates to a novel flap structure and an operating method thereof for water conservancy projects, that is, an energy-saving three-leaf flap flap and an operating method thereof. Background technique [0002] The flap door is a one-way check valve to prevent backflow of external water. It is installed at the outlet of the liquid flow channel and is mainly used in water conservancy and municipal engineering. [0003] At present, the flap door equipped with the traditional large-scale flow channel is basically a whole flap door. Its volume and weight are huge, it is not easy to open the flap door (especially when the water output is small), and it consumes a lot of energy; when it is closed, Due to the effect of gravity, the flap door has a greater force when it is closed downwards, which greatly damages the flow channel. Contents of the invention [0004]...
