FIG. 1 is a schematic structural view of an anti-reverse sewer cover with a movable valve in a free state;

fig. 2 is a schematic structural view of a sewer cover for preventing reverse water, and a movable valve is in a state of closing a water inlet.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the sewer cover for preventing reverse water supply comprises a manhole cover 1, a sealing ring 3, a manhole ring 2, a movable valve 4, a floating device 5, a connecting seat 7, a connecting shaft 8 and a fixing screw 9.

The walling crib 2 is used for being installed at the top of sewer, is equipped with apron groove 21 on the walling crib 2, and annular array is equipped with a plurality of screw holes 22 in the apron groove 21. Sealing ring 3 is the rubber ring, and sealing ring 3 is installed in apron groove 21, and the top of well lid 1 is equipped with a plurality of screw holes 12, and well lid 1 is installed in apron groove 21, and screw hole 12 sets up with screw hole 22 relatively to screw hole 12 is the counter bore, and set screw 9 inserts in screw hole 12, and is connected with screw hole 22, fixes well lid 1 in apron groove 21, and sealing ring 3 realizes the sealed of well lid 1 and walling crib 2.

Be equipped with a plurality of water inlets 11 on the well lid 1, connecting seat 7 is installed in the bottom of well lid 1, and is located one side of water inlet 11, and connecting axle 8 is fixed on connecting seat 7, and movable valve 4 rotates to be installed on connecting axle 8, and

movable valve

4 and 11 one-to-ones of water inlet to relative setting, movable valve 4 is located the sewer. The front surface of the movable valve 4 opposite to the water inlet 11 is provided with a valve sealing gasket 6, and the valve sealing gasket 6 is a rubber gasket and is used for sealing the water inlet 11.

The floating device 5 comprises an air bag or a floating ball which is fixed on the back of the movable valve 4.

When the water level in the sewer rises to be close to the well lid 1, the air bag or the floating ball pushes the movable valve 4 to rotate towards the water inlet 11 under the action of buoyancy, when the water level in the sewer rises to the well lid 1, the movable valve 4 is tightly pressed on the water inlet 11 under the action of the air bag or the floating ball, the valve sealing gasket 6 realizes the sealing of the water inlet 11, and the sewage in the sewer cannot overflow and is limited in the sewer. Sealing ring 3 also prevents that sewage from flowing out from the gap between well lid 1 and the walling crib 2.

In order to prevent that activity valve 4 antiport is equipped with limiting plate 71 on the connecting seat 7, the contained angle A between limiting plate 71 and the well lid 1 is less than 90 to make activity valve 4 can only rotate to water inlet 11, can not rotate to the direction of keeping away from water inlet 11, guarantee that activity valve 4 can seal water inlet 11.

The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the claims of the present invention.
