Abstract

The utility model relates to a sewer line odor proof and overflowing proof device, which is an inner hollow spherical shell structure. The spherical shell is provided with the structure therein, upper end of the spherical shell is communicated with a drainage pipe, and lower end of the spherical shell is communicated with the sewer line. Due to the structure, when the sewer line is blocked and sewage is refluxed, a floating ball in the spherical shell is lifted to block the pipe mouth of the drainage pipe; therefore reaching the aim of preventing the sewage in the sewer line from being refluxed and overflowed from the drainage pipe efficiently. The utility model has the advantages of simple structure, convenient installation and low cost, etc.

Description

Sewer pipe deodorization anti-overflow device

Technical field

The utility model relates to a kind of improvement of sewer pipe anti-overflow device, particularly a kind of sewer pipe deodorization anti-overflow device.

Background technology

In civilian construction, the sewer pipe of pond, urinal generally adopts the trap structure, and the waste gas rising of blocking in the pipeline hypomere with the water body in the trap escapes, and plays the function of deodorization.But when sewer pipe blocks and the waste water that takes place when rise refluxing, trap can not play the effect of blocking-up, and waste water is back to pond, urinal by trap, even spill-over pollutes to ground, influences sanitation of environment.

Summary of the invention

The purpose of this utility model is exactly that a kind of sewer pipe deodorization anti-overflow device that can prevent the sewer pipe sewage backflow, its simple structure, easy for installation, with low cost will be provided.

The purpose of this utility model is achieved in that a kind of sewer pipe deodorization anti-overflow device, this device is the structure of interior empty spherical shell 1, be provided with ball float 2 in spherical shell 1, the upper end of spherical shell 1 communicates with gutter 3, and the lower end of spherical shell 1 communicates with sewer pipe 4.

Owing to adopt said structure,, reach and prevent that effectively sewage is from the excessive purpose of gutter backflow in the sewer pipe so when sewer pipe blocked sewage backflow, the ball float in the spherical shell rose the mouth of pipe of gutter is blocked.The utility model also has advantages such as simple in structure, easy for installation, with low cost.

Description of drawings

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a kind of enforcement illustration of the present utility model.

Fig. 3 is the another kind of illustration of implementing of the present utility model.

Fig. 1 double as Figure of abstract.

Among the figure: 1, spherical shell, 2, ball float, 3, gutter, 4, sewer pipe.

The specific embodiment

As shown in Figure 1, a kind of sewer pipe deodorization anti-overflow device, this device is the structure of interior empty spherical shell 1, is provided with ball float 2 in spherical shell 1, and the upper end of spherical shell 1 communicates with gutter 3, and the lower end of spherical shell 1 communicates with sewer pipe 4.

Under normal circumstances, as shown in Figure 2, the water level of spherical shell 1 inner chamber is in the centre position, and the mouth of pipe of the gutter 3 that ball float 2 communicates with spherical shell 1 top breaks away from, and the waste gas of the water body of spherical shell 1 inner chamber in can shutoff sewer pipe 4 plays the effect of deodorization.

When sewer pipe 4 obstructions causing waste water rising backflow takes place when, as shown in Figure 3, the water level of spherical shell 1 inner chamber rises to full state, ball float 2 is under buoyancy function, be closely buckled in the mouth of pipe of the gutter 3 that spherical shell 1 top communicates, close waste water and continue the passage that rising is back to gutter 3, play the effect of anti-overflow.

Claims

1. sewer pipe deodorization anti-overflow device, it is characterized in that: this device is the structure of interior empty spherical shell (1), be provided with ball float (2) in spherical shell (1), the upper end of spherical shell (1) communicates with gutter (3), and the lower end of spherical shell (1) communicates with sewer pipe (4).
