Abstract
The utility model discloses a novel flexible check valve for a floor drain, which comprises a stainless steel flat leaking net, wherein a flexible duckbill valve is embedded on the stainless steel flat leaking net, and the bottom part of the flexible duckbill valve is provided with a sealing surface. When water drainage is required for road surface, a kitchen and a lavatory or a bathroom, sewage props the sealing surface open under the action of gravity, water flows out from the flexible duckbill valve, and the sealing surface is closed up after water outflow is finished, thus effectively preventing stink or mosquitoes from coming up. When a sewer pipe is blocked or rainstorm begins, the external water level rises, and the sealing surface of the flexible duckbill valve clings to the back surface of the whole flexible duckbill valve due to pressing, thus realizing sealed water closing, and effectively preventing the sewage from overflowing.
Description
Technical field
The utility model relates to and a kind ofly is used between building washroom, kitchen or the floor drain on the surface of the street, relates in particular to a kind of floor drain that prevents that sewage from instead overflowing.
Background technology
Between building washroom, kitchen or on the surface of the street, in order to make in the room or the ponding of surface of the street or sewage flow in the sewer, between the kitchen, washroom or surface of the street all be equipped with floor drain.Floor drain in the market roughly is divided into two big classes: a class is a deodorization type floor drain, i.e. hydrolock floor drain, and it utilizes water in the trap to stop on the foul odour in the sewer and escapes; But this mode need take between the kitchen and the washroom under the space of one deck, influence the height of its furred ceiling and attractive in appearance, and the sewage in the sewer instead overflow do not have interception; Another kind ofly be the counnter attack type floor drain that overflows, " a kind of counnter attack overflow backwater floor drain " that provides as Chinese patent 962301825, it is to have flanging in the upper end of conduit, chamber suitable for reading of turning one's coat also has flanging, suitable for reading of the upper end of conduit and the chamber of turning one's coat has a pad, top in the chamber of turning one's coat has weep hole, and the shape of inversion object is arranged in the chamber of turning one's coat.Utilize the buoyancy of being inverted the shape object, it is floated in the chamber of turning one's coat, block the end opening in the chamber of turning one's coat, make floor drain reach the purpose that counnter attack is overflow.The sewage that this floor drain can be sealed in the sewer instead overflows, but owing to the sealing of being inverted the shape object and turn one's coat between the chamber is good inadequately, overflows so can't prevent the foul smell in the sewer.
The utility model content
The utility model purpose is to provide a kind of flexible one way valve of floor drain of new structure, by flexible duckbill valve, can prevent that the sewage in the sewer from instead overflowing, and can avoid foul smell or mosquito in the sewer to come up again.
The technical scheme that realizes the utility model purpose is:
The flexible one way valve of a kind of novel floor drain comprises that stainless steel flat plate slips through the net, and it is characterized in that: be inlaid with a flexible duckbill valve on described stainless steel flat plate is slipped through the net, a sealing surface is arranged at described flexible duckbill valve bottom.
It is square or circular that stainless steel flat plate is slipped through the net.
The utility model compared with prior art has following advantage:
1. flexible duckbill valve is uncovered up, sealing surface down.When surface of the street, kitchen and toilet or bathroom need descend water, sewage strutted sealing surface under action of gravity, and flexible duckbill valve water outlet, the water outlet back sealing surface closure that finishes effectively like this prevents that foul smell or mosquito from coming up.When drainage pipeline stopped up or rains in torrents, outer water level rose, and flexible duckbill valve sealing surface and whole flexible duckbill valve back side pressurized are fitted, and realized sealing and closed water, had effectively prevented sewage outflow.
2. flexible duckbill valve adopts the flexible rubber structure, has corrosion resistant, anti-clamping stagnation, need not the manual maintenance maintenance etc. characteristics.
3. utilize oppositely to close to press and realize positiver sealing, improved the anti-overflow effect with self elasticity.
4. general with old-fashioned floor drain specification, can change at any time.

1. stainless steel flat plate 2. flexible duckbill valve 3. sealing surfaces of slipping through the net
The specific embodiment
As can be seen, the flexible one way valve of a kind of novel floor drain comprises that square or circular stainless steel flat plate slips through the net, and is inlaid with a flexible duckbill valve on described stainless steel flat plate is slipped through the net from Fig. 1 and Fig. 2, and a sealing surface is arranged at described flexible duckbill valve bottom.When surface of the street, kitchen and toilet or bathroom need descend water, sewage strutted sealing surface under action of gravity, and flexible duckbill valve water outlet, the water outlet back sealing surface closure that finishes effectively like this prevents that foul smell or mosquito from coming up.When drainage pipeline stopped up or rains in torrents, outer water level rose, and flexible duckbill valve sealing surface and whole flexible duckbill valve back side pressurized are fitted, and realized sealing and closed water, had effectively prevented sewage outflow.
