Description

Float type anti-sewage checker

technical field

The utility model relates to an anti-sewage backflow device installed in the urinal of a building, in particular to a floating ball type anti-sewage backflow device.

Background technique

At present, there is a U-shaped pipe at the sewer pipe in the residents' homes. A certain amount of water is stored in the U-shaped pipe to prevent the odor in the sewer from overflowing. The pipe and the urinal flow back into the room, which brings troubles to people's life.

Contents of the invention

The purpose of the utility model is to overcome the above disadvantages and provide a floating ball type anti-sewage check device for preventing sewage and feces from flowing back into the room.

The purpose of this utility model is achieved in this way: the floating ball type anti-sewage checker is composed of a water inlet pipe, a floating ball chamber, a water outlet pipe, a floating ball, and an odor-proof elbow. The floating ball chamber is in the shape of a conical tube. There is a floating ball, the upper part of the floating ball chamber is connected with the water inlet pipe, and the bottom is connected with the water outlet pipe, and the upper end of the anti-odor elbow is threaded and sealed and connected to the inner wall of the water outlet pipe at the bottom of the floating ball chamber. The inner diameter of the water inlet pipe on the top of the float chamber is the same as that of the deodorant elbow, and the diameter of the float is greater than the inner diameter of the water inlet pipe on the top of the float chamber and less than the inner diameter of the outlet pipe at the bottom of the float chamber.

When specifically using the utility model, the utility model is installed below the urinal, the water inlet pipe at the upper end of the float chamber is connected with the urinal drain, and the water outlet at the lower end of the anti-odor elbow is connected with the sewer pipe in the building. The drainage of the water pipe is blocked. When the water level in the downpipe rises, the sewage enters the float chamber through the anti-odor elbow. Sewage will not flow back into the urinal and into the room.

The utility model has the advantages of simple structure, convenient assembly, safe use, can prevent the backflow of sewage, ensure indoor sanitation, and relieve the worries of low floors, especially residents on the first floor.

Description of drawings

Accompanying drawing is the structural sectional view of the utility model.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings: the floating ball type anti-sewage checker is composed of a water inlet pipe 1, a floating ball chamber 2, a water outlet pipe 3, a floating ball 4, and an odor-proof elbow 5. The floating ball chamber 2 It is in the shape of a conical tube. There is a floating ball 4 inside the floating ball chamber 2. The upper part of the floating ball chamber 2 is connected with the water inlet pipe 1, and the bottom is connected with the water outlet pipe 3. On the inner wall of the water outlet pipe 3. The inner diameter of the water inlet pipe 1 on the top of the float chamber 2 is identical to the inner diameter of the deodorant elbow 5, and the diameter of the float 4 is greater than the inner diameter of the water inlet pipe 1 on the top of the float chamber 2 and less than the inner diameter of the outlet pipe 3 at the bottom of the float chamber 2. This structure is convenient for making of the present utility model, and when assembling, ball float 4 is packed into ball float chamber 2 from the water outlet pipe 3 at the bottom of ball float chamber 2, and the upper end of deodorant elbow 5 is thread-tightly connected to the inner wall of water outlet pipe 3 to ensure floating. Ball 4 is in the ball float chamber 2 all the time, can not enter in the water inlet pipe 1 and the deodorant elbow 5.
