Example 1
As shown in fig. 1:
the drain floor drain capable of preventing sewage from flowing back is composed of a shell unit and an inner drain unit, and the two units are connected by means of threads.
The outer shell of the floor drain is ring-shaped, and the inner wall is a connecting thread. The outer shell is fixed with the floor by cement mortar or waterproof adhesive. The inner drainage unit is cylindrical and consists of an inner cylinder, a movable rod, a fixed frame, a telescopic spring and a drainage plate. The inner drainage unit pressure port is provided with a threaded connection gasket, the top is provided with 6 fastening lugs, the shell and the threads of the inner drainage unit are screwed up through the fastening lugs, and meanwhile, the connection gasket is pressed tightly, so that a sealing effect is achieved. The drain bar is fixedly connected with the movable rod, the movable rod penetrates through the middle inner hole of the fixed frame to be fixed, the outer surface of the movable rod is smooth and wear-resistant, the diameter of the inner hole of the fixed frame is 1-3 mm greater than the outer diameter of the movable rod, and the drain bar and the movable rod can integrally move up and down by virtue of the telescopic spring. The outer diameter of the drain plate is 5-10mm larger than the outer diameter of the inner cylinder. The thickness of the inner cylinder is not less than 3.0mm, and the lower opening surface is flat. And a silica gel gasket is arranged at the contact part of the drain plate and the bottom of the inner cylinder, the whole gasket is adhered to the drain plate, the inner diameter of the drain plate gasket is smaller than the diameter of the inner cylinder by 5-10mm, and the outer diameter of the drain plate gasket is the same as the outer diameter of the drain plate.
In the drainage floor drain, sewage is converged into the floor drain, and the drainage panel and the sewage interception plate intercept sundries of hair or large particles to prevent the inner drainage unit and the sewer from being blocked. When the sewage quantity flowing into the floor drain exceeds 1/6-1/5 of the total volume of the inner cylinder, the compression spring is compressed, the drain board moves downwards, and the sewage is discharged out of the floor drain and enters the sewer. After the drainage is finished, the drainage plate moves upwards to be in contact with the lower opening of the inner cylinder under the action of the telescopic spring, and the drainage gasket on the drainage plate is sealed to block odor or mosquito reverse strings of the sewer from entering a room. Because the building goes out the reason such as drain pipe jam or flowing water are unsmooth, lead to the sewage in the sewer to flow back upwards, interior drainage unit and shell unit resist through threaded connection that interior drainage unit is because of the water pressure come-up, the drain bar is under ascending water pressure effect, closes more tightly with the inner tube lower mouth, has blocked sewage and has flowed back into indoor through the drainage channel, and the drainage floor drain has played the effect that prevents sewage and flow back simultaneously. In order to prevent the inner drainage unit from being blocked by sundries and having the phenomenon of odor reversion and the like, the threads are loosened by using a wrench through fastening lugs at intervals of a week at maximum, the inner drainage unit is taken out, cleaned and reinstalled. The drainage floor drain has simple structure and convenient use and maintenance.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims. The information disclosed in the background section herein is only for enhancement of understanding of the general background of the utility model and is not to be taken as an admission or any form of suggestion that this information forms the prior art already known to those of ordinary skill in the art.
