Abstract

The application discloses a domestic water pipeline anti-back-flow device, which relates to the field of life and comprises a drain pipe, wherein the bottom of the drain pipe is rotationally connected with a rotatable sealing cover through a rotating shaft, a sealing surface is arranged between the sealing cover and the drain pipe, a suspension part is fixed at the bottom of the sealing cover, the suspension part can be driven to move towards the water inlet end of the drain pipe along with the rising of the sewage liquid level in an external sewage pipeline, the sealing cover can be driven to rotate around the rotating shaft in the moving process of the suspension part, and a gap between the sealing cover and the drain pipe can be sealed by matching with the sealing surface, so that sewage is prevented from reversely flowing out of the drain pipe; and along with the pressure of sewage in the external pipeline is bigger, the buoyancy of the suspension piece is bigger, and then the sealing cover and the drain pipe are extruded more tightly, the sealing performance is higher, and the anti-water-return performance of the device is greatly improved.

Description

Anti-water installation is prevented to domestic water pipe line

Technical Field

The utility model belongs to the field of life specifically is a water installation is prevented returning by domestic water pipe line.

Background

In the life, among the drainage pipeline of kitchen or bathroom, when the blocking phenomenon appears, because rivers can't circulate, can make domestic drainage pipeline, the phenomenon of returning water appears.

In addition, when the public sewage discharge pipeline is blocked to cause reverse water, the sewage pressure in the public pipeline is higher, so that the one-way valve in the household sewage pipeline is easily damaged, and the sewage reverse water is caused.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved is as follows:

the utility model provides a not enough to prior art, the utility model provides a reverse water installation is prevented to domestic water pipeline circuit has solved the problem that mentions in the background art.

The technical scheme is as follows:

in order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

the utility model provides a domestic water pipeline line prevents anti-device of swimming, includes the drain pipe, the bottom of drain pipe is rotated through the pivot and is connected with rotatable sealed lid, be provided with sealed face between sealed lid and the drain pipe, and the bottom of sealed lid is fixed with the suspension.

In a possible implementation, the sealing surface may be the sealing cover and the drain pipe itself, or may be an additional sealing gasket.

In one possible implementation, the suspension is made of a material having a density less than water, and the suspension is insoluble in water.

Has the beneficial effects that:

the suspension piece can be driven to move towards the water inlet end of the drain pipe along with the rising of the sewage liquid level in the external sewage pipeline, the sealing cover can be driven to rotate around the rotating shaft in the moving process of the suspension piece, and the gap between the sealing cover and the drain pipe can be sealed by matching the sealing surface, so that the sewage is prevented from reversely flowing out of the drain pipe;

and along with the pressure of the sewage in the external pipeline is larger, the buoyancy of the suspension piece is also larger, the sealing cover and the drain pipe are extruded more tightly, the sealing performance is higher, and the anti-reverse performance of the device is greatly improved.

Detailed Description

The embodiment of the application solves the problems in the prior art by providing the anti-reverse device for the household water pipe line.

In order to solve the problems, the technical scheme of the application has the following general idea:

as shown in fig. 1, the anti-reverse device for the household water pipeline comprises a drain pipe 3, wherein the bottom of the drain pipe 3 is rotatably connected with a rotatable sealing cover 2 through a rotating shaft 5, a sealing surface 1 is arranged between the sealing cover 2 and the drain pipe 3, a suspension part 4 is fixed at the bottom of the sealing cover 2, and the suspension part 4 can be foam, an air bag and the like.

In some examples, the sealing surface 1 may be the sealing cap 2 and the drain pipe 3 itself, or may be an additional sealing gasket.

In some examples, the suspension 4 is made of a material that is less dense than water, and the suspension 4 is insoluble in water.

By adopting the technical scheme:

the drain pipe 3 is arranged on a household drain pipeline, and sewage can normally pass through the drain pipe 3 and is discharged to an external sewage pipeline in the using process;

when the external sewage pipeline has a reverse water phenomenon, the suspension piece 4 can be driven to move towards the water inlet end of the drain pipe 3 along with the rising of the sewage liquid level in the external sewage pipeline, the sealing cover 2 can be driven to rotate around the rotating shaft 5 in the moving process of the suspension piece 4, and the gap between the sealing cover 2 and the drain pipe 3 can be sealed by matching the sealing surface 1, so that the sewage is prevented from reversely flowing out of the drain pipe 3;

in addition, the larger the pressure of sewage in the external pipeline is, the larger the buoyancy of the suspension 4 is, the tighter the sealing cover 2 and the drain pipe 3 are extruded, the higher the sealing performance is, and the anti-water-return performance of the device is greatly improved.

Finally, it should be noted that: it should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the scope of the invention.
