The technical solution of the utility model is: a kind of drainage pipe automatic valve device, formed by floor drain operator end cap, upper hopper, check ball, lower funnel and drainage outlet and external panel sequential combination, floor drain operator end cap is connected with upper hopper, large mouthful of large mouthful of inserting lower funnel of upper hopper, insert the check ball in the empty chamber in the middle of upper hopper and lower funnel, the end mouth of lower funnel inserts the import of drainage outlet pipe.

The plastic material manufacturing of check ball, slightly larger in diameter are in drainage outlet pipe diameter, and the difference of large mouthful of sectional area of its sectional area and upper hopper is not less than the sectional area of drainage outlet pipe.

The vertical cartel of upper hopper, check ball, lower funnel consists of the body of drainage pipe automatic valve device, and the osculum diameter of body is half of large mouthful, highly is 3 times of check bulb diameter between the cavity upper and lower opening of body, and internal diameter is 2 times of check bulb diameter.

External structure is the sectional type structure.Formed by the external panel of floor drain or drainage system interface section, anti-automatic valve main pipe (abbreviation valve body) two macrostructures that overflow that emit.Wherein external panel is ground plane, square-outside and round-inside, and interior circular diameter is the external diameter of valve body, is convenient to valve body and freely plugs, the valve body lower end directly is plugged in the drainage pipe.The valve body internal construction is, at first the loam cake imports such as existing floor drain and drainage system rain operator, sink hole is combined with the end cap of valve body, and wherein the floor drain intake section is operator, and other parts are cover plate, and external diameter equals circular diameter in the external panel; Valve body adopts the funneling concentric reducing that (identical with water inlet aperture) suitable for reading is little, end opening is large; Be inserted in a plastic ball in it, its slightly larger in diameter is in drainage pipe diameter, and its sectional area should be not less than the gutter sectional area with the difference of large mouthful sectional area; And then insert in the concentric reducing place underground big upper and lower small mouth (identical with drainage pipe diameter, and be connected with gutter) and consist of valve body.

The beneficial effects of the utility model are: during normal draining, sewage emits the check ball in the automatic valve that overflows to produce buoyancy to anti-, makes the check ball by jacking, and sewage flows through under the check ball; Overflow and during general flavor when emitting, because the check ball is got lodged in bell mouth by sewage or the foul smell jacking that makes progress, therefore stoped sewage and foul smell retrograde; Along with resident family upstairs constantly increases draining, make this valve Outer Tube internal pressure increasing, can make obstruction place the sliding even disintegration of pine occur; When even pressure is not high, anti-emit excessive automatic valve if had by other outfall of blocked pipeline, also be convenient to stick up with skin the instrument of simply calming the anger such as son and just can solve the line clogging problem; At ordinary times, because the check ball replaces traditional pressure of water seal on mouth at the bottom of the valve, so end mouth is water not, often is to do cleanly, and the drawback of having avoided traditional water seal " to deposit sewage envelope foul smell " solved smelly water and infested problem well; Upper part and the bottom of this valve belongs to peg graft to twist mouth structure, is convenient to put into and takes out the check ball, is conducive to clear up obstruction.
