Detailed Description

The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1-5, the utility model relates to a to open square flap valve, including the slope set up pat a seat 7, articulate pat a seat 7 left and right sides and to open the left side of setting and pat a door 1 and the right side of setting and pat a door 2, a left side is patted a door 1 and is patted a door 2 for the arc door plant with the right side, pat and be provided with supporting component 8 in the middle of the seat 7, the both sides of a left side is patted a door 1 and the right side is patted a door 2 all with pat a seat 7 and supporting component 8 sealing contact, the inclination of clapping a seat 7 is 85 ~ 87.

The utility model discloses change left side flap door 1 and right side flap door 2 and the articulated position of flap seat 7 into side vertical arrangement by upper portion, left side flap door 1 and right side flap door 2 one side are provided with flap door lug 3, flap door seat 7 one side is provided with door seat lug 4, flap door lug 3 and door seat lug 4 are connected through hinge 5. Specifically, the hinge shaft 5 can be made of stainless steel, the hinge shaft seat bushing is made of a copper-based alloy self-lubricating shaft sleeve, and the flap valve seat 7, the left flap valve 1 and the right flap valve 2 can be made of carbon steel or stainless steel according to actual working conditions.

The utility model discloses the flap valve comprises two opposite opening flap valves, and left flap valve 1 and right flap valve 2 change the arc door plant into by conventional plate structure, and the running resistance is little, and opening angle is big, and the impact is little when closing the door, has eliminated the swirl that produces when water hammer and play water. Considering that the bearing water pressure is larger, a support rib 6 is arranged in the arc door panel.

For making a left side flap valve 1 and a right side flap valve 2 be close to hole central part and 8 laminatings of supporting component, make things convenient for the installation of water seal simultaneously, the utility model discloses a supporting component 8 includes U-shaped mounting panel, clamp plate and connecting block, and two vertical parts of U-shaped mounting panel are respectively through clamp plate and the fixed P type rubber water seal 9 of connecting block, and clamp plate and connecting block are located the 9 vertical part both sides of P type rubber water seal respectively, and specifically, connecting block and clamp plate are rectangular shape, adopt the stainless steel bolt to fix together P type rubber water seal 9, clamp plate, connecting block, U-shaped mounting panel. Because the U-shaped mounting panel often receives water impact, for the steadiness of guaranteeing U type mounting panel, the utility model discloses supporting component 8 is still including setting up the isosceles right angle reinforcing plate at the U-shaped mounting panel back to improve the life who claps a seat 7.
