Abstract
The utility model relates to a return overflow preventing floor drain which belongs to a floor drain used on the drain outlets of sewers. The utility model is the improvement of the existing floor drains. The utility model is characterized in that the utility model comprises an outer sleeve, a panel, a leaking cylinder and an outer sleeve pipe, wherein, an inner sleeve pipe is arranged on the outer sleeve pipe, a water inlet is arranged on the inner sleeve pipe, a floating plate is arranged in the inner sleeve pipe, and a stopper is arranged on the upper part of the inner sleeve pipe. The utility model has the advantages of good tightness and reasonable structure. The utility model can prevent the overflow of smell or sewage in sewers and protect indoor environmental sanitation effectively.
Description
The utility model relates to the floor drain that a kind of sewer outfall is used.
Employed in the past indoor floor drain all is directly to leak, and usually has addle, peculiar smell etc. and invades indoor.So the overflow-proof floor drain occurred, as the automatic closed floor drain that Chinese patent 94230829.8 provides, it is to adopt a movable floor, and base plate one side connects firmly weight, and weight gravity closes base plate to seal tube bottom aperture Lou to realize sealing automatically by this.But the poor sealing of this floor drain after use a period of time, is difficult to prevent that the oxious gas in the sewer from escaping.
The purpose of this utility model provides a kind of good airproof performance, novel overflow-proof floor drain rational in infrastructure.
The purpose of this utility model is to adopt following technical proposal to realize: this overflow-proof floor drain comprises the leakage tube and an outer tube that links to each other with the leakage tube of shell, panel, panel bottom, delivery port is arranged on the outer tube, inner sleeve is arranged in the outer tube, water inlet is arranged on the inner sleeve, be provided with kickboard in the inner sleeve, and blind be set on the top of inner sleeve.Form water seal when between leakage tube and outer tube water being arranged, kickboard is floated under buoyancy function, makes Lou tube exit seal.During use, when ground water entered Lou tube from panel after, the weight of water can make kickboard sink, and current are by water seal, in the space inflow sewer between shell and outer tube.
The utility model is owing to be provided with inner sleeve in outer tube, make in the water seal capacity of water big, is difficult for dry; In addition, the kickboard in the inner sleeve not only makes the sealing performance of floor drain obviously improve, and can prevent that the sewage in the sewer from returning excessive.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the sectional view of the overflow-proof floor drain that provides of the utility model.
As shown in the figure, this overflow-proof floor drain comprises shell 1, panel 2, inner sleeve 3, outer tube 4, leaks tube 5 and kickboard 6 etc.Panel 2 connects with shell 1 by screw thread.On the outer tube 4 delivery port is arranged, on the inner sleeve 3 water inlet is arranged, and the position of delivery port is higher than water inlet.Kickboard 6 in the inner sleeve 3 adopts rubber to make.Be provided with blind 7 in inner sleeve 3 tops and leakage tube 5 junctions.The position of blind 7 is lower than the delivery port position of outer tube 4.After forming water seal between leakage tube 5 and the outer tube 4, kickboard 6 is floated, and is blocked by blind 7 at last.In the rubber kickboard 6 cavity is arranged.The size design of cavity will make the buoyancy of kickboard 6 be a bit larger tham the weight of kickboard 6.Like this, as long as there is water to enter Lou the tube 5 from panel 2, the deadweight of water just can make kickboard 6 sinkings, and current can be entered in the sewer through the delivery port of outer tube 4 by the water inlet of inner sleeve 3.Yet oxious gas in the sewer or sewage can not be excessive owing to water seal and kickboard stops, can effectively protect indoor environmental hygiene.
