Detailed Description

Referring to fig. 1 to 3, in the embodiment of the present invention: pneumatic flap valve is used in filtering pond, including filtering pond 1, wastewater disposal basin 3 has been pour to one side in filtering pond 1, and overflow pond 6 has been pour at the top of wastewater disposal basin 3, and the binding face of filtering pond 1 and wastewater disposal basin 3 is provided with connecting plate 5, and one side that is located filtering pond 1 inside of connecting plate 5 is the vertical form symmetry and is equipped with a set of slide rail 13, and sliding connection has slider 12 on slide rail 13, and the pin joint has the board 8 that turns over on slider 12, and the both sides pin joint that turns over board 8 has connecting rod 7, and the tip swing joint of connecting rod 7 is at the top front end of connecting plate.

In fig. 2, the lower extreme of connecting plate 5 has been seted up delivery port 11, and the area of delivery port 11 is the half of turning over 8 areas, and one side that delivery port 11 is located filtering pond 1 is equipped with the round retaining ring, and delivery port 11 is used for releasing waste water, opens and shuts through turning over 8, and the effect of retaining ring is: because the turning plate is connected on the sliding rail 13 in a sliding way, a certain plane difference exists between the turning plate and the connecting plate 5, the turning plate 8 cannot be flatly attached to the connecting plate 5 and naturally cannot completely seal the water outlet 11, and therefore, a check ring is additionally arranged to eliminate the difference caused by the sliding rail 13, so that the turning plate 8 can be tightly attached to the check ring to seal the water outlet 11.

In fig. 2, a connecting piece 16 is arranged at one end of the turning plate 8, which is attached to the water outlet 11, and a crank arm connecting rod 18 is connected to the connecting piece 16 through a pin, the crank arm connecting rod 18 penetrates through the water outlet 11 and extends into the wastewater tank 3, the connecting piece 16 is movably connected with the crank arm connecting rod 18, so that torsion caused by the fixed connection of the crank arm connecting rod 18 is prevented in the rotating process of the turning plate 8, and the crank arm connecting rod 18 can push the turning plate 8 to rotate obliquely upwards by utilizing a special structure of the crank arm connecting rod 18, so that the water outlet 11 is opened.

In fig. 2, the end of the crank arm connecting rod 18 is movably connected with a connecting rod 9, the end of the connecting rod 9 is movably connected with a cylinder 10, the cylinder 10 is located at the upper end of the wastewater disposal basin 3, the cylinder 10 is sleeved with a ring sleeve 4, the ring sleeve 4 is welded at the top of the wastewater disposal basin 3, the cylinder 10 is a power part of the whole valve, the cylinder 10 pushes the crank arm connecting rod 18 to move obliquely downwards through the connecting rod 9, but due to the structure of the crank arm connecting rod 18, when the whole crank arm connecting rod moves downwards, the upper end moves upwards to push the turning plate 8 to move obliquely upwards, and the ring sleeve 4 is used for fixing the cylinder 10.

In fig. 3, a circle of peripheral edge 14 is arranged at the center of the inner surface of the turning plate 8, a circle of inner peripheral edge 15 is arranged inside the peripheral edge 14, an embedding groove 17 is formed between the peripheral edge 14 and the inner peripheral edge 15, the embedding groove 17 is filled with silica gel, and the silica gel is filled with half of the depth of the embedding groove 17, when the valve is closed, the peripheral edge 14 and the inner peripheral edge 15 on the inner side of the turning plate 8 embed a check ring of the water outlet 11, so that the check ring of the water outlet 11 is attached to the silica gel in the embedding groove 17, under the action of pulling of the cylinder 10 and water pressure, the check ring presses the silica gel to complete sealing, the turning plate in traditional fixed connection is changed into sliding connection, thereby eliminating the problem of loosening of a joint caused by frequent movement of the turning plate, when the valve is opened, the cylinder 10 pushes the crank arm connecting rod 18 through the connecting rod 9, the crank arm connecting rod 18 pushes the turning, thereby slide a distance through slider 12 and rotate again inwards in slide rail 13 to emit waste water, turn over board 8 sliding connection and not only eliminate the pressure of water pressure to junction in the in-process that opens and shuts, also prevent simultaneously that traditional lever from opening and shutting from causing to turn over board 8 and the delivery port 11 laminating problem that closely leads to leaking.

The length of slide rail 13 is half of turning over board 8 length, and the height of slide rail 13 is slide rail 13 width twice, and the spout degree of depth and the silica gel thickness of filling of slide rail 13 are equal, turns over board 8 with traditional fixed connection and becomes sliding connection to eliminate because the board 8 frequently moves and the not hard up problem of joint that leads to of turning over.

In fig. 1, a water distribution pipe 2 is arranged at the bottom end inside the filter tank 1, a gravel layer and a filter material layer are arranged at the top of the water distribution pipe 2, and the water distribution pipe 2 releases back-flushing water flow to flush the gravel layer and the filter material layer.

The utility model discloses a theory of operation is: when the device is used, the water distribution pipe 2 releases backwash water flow to wash a gravel layer and a filter material layer, the valve is opened after washing, the air cylinder 10 (with the model of CDA2HB40-50) pushes the crank arm connecting rod 18 to move obliquely downwards through the connecting rod 9, but due to the structure of the crank arm connecting rod 18, when the whole body moves downwards, the upper end moves upwards to push the turning plate 8 to move obliquely upwards, so that the valve is opened, washing water flows out through the water outlet 11, after the release is finished, the valve is closed, the air cylinder 10 pulls the crank arm connecting rod 18 through the connecting rod 9 to drive the turning plate 8 to be attached to the water outlet 11, because the turning plate is connected to the sliding rail 13 in a sliding manner, a certain plane difference exists between the turning plate 8 and the connecting plate 5, the turning plate 8 cannot be attached to the connecting plate 5 flatly, and the water outlet 11 cannot be sealed completely naturally, so that the, when the valve is closed, the outer peripheral edge 14 and the inner peripheral edge 15 on the inner side of the turning plate 8 embed the check ring of the water outlet 11, so that the check ring of the water outlet 11 is attached to the silica gel in the embedding groove 17, and under the action of pulling of the cylinder 10 and water pressure, the check ring presses the silica gel to complete sealing.

The above-mentioned, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
