Detailed Description

The present utility model will be further described in detail with reference to examples so as to enable those skilled in the art to more clearly understand and understand the present utility model. It should be understood that the following specific embodiments are only for explaining the present utility model, and it is convenient to understand that the technical solutions provided by the present utility model are not limited to the technical solutions provided by the following embodiments, and the technical solutions provided by the embodiments should not limit the protection scope of the present utility model.

Examples

As shown in fig. 1 and 2, this embodiment provides a structure for preventing water backflow applied to sanitary installation, which is mainly used for preventing water backflow in a toilet, and the structure adopts a design concept of preventing water backflow in a toilet by combining dredging and blocking, and mainly uses dredging and blocking as assistance, so as to solve the defects existing in the prior art that the water backflow preventing measures of blocking are mainly adopted.

In this embodiment, be applied to sanitary installation prevent water backflow structure including the first downcomer that is used for connecting the washing machine drain pipe, be used for connecting the second downcomer of floor drain, be used for connecting the third downcomer of closestool, be used for connecting the fourth downcomer of wash basin, with first downcomer, second downcomer, third downcomer and fourth downcomer connected main drain pipe, set up the overflow subassembly on first downcomer, second downcomer, third downcomer and the fourth downcomer, the overflow main pipe of being connected with overflow subassembly, the exit end of overflow main pipe passes the outer wall and is connected with vertical drain pipe at this end. The structure is a sparse structural design, wherein the overflow assembly comprises a first inclined three-way pipe arranged on the first sewer pipe, a second inclined three-way pipe arranged on the second sewer pipe, a third inclined three-way pipe arranged on the third sewer pipe and a fourth inclined three-way pipe arranged on the fourth sewer pipe.

In this embodiment, the first diagonal three-way pipe, the second diagonal three-way pipe, the third diagonal three-way pipe and the fourth diagonal three-way pipe have the same structure, and are named herein for convenience of distinction, the following description bases on the first diagonal three-way pipe, the upper end and the lower end (vertical) of the first diagonal three-way pipe are respectively communicated with the first sewer pipe, the third end of the diagonal three-way pipe is communicated with the overflow main pipe, and the inclined direction of the third end of the diagonal three-way pipe is inclined upwards to the right (with the illustration as the description base); the implementation principle of the technical scheme is as follows: when the water is reversed, sewage flows back to the first sewer pipe from the main drain pipe, when the water level reaches the inclined third end of the first inclined three-way pipe, overflows to the overflow main pipe through the inclined third end, then flows to the vertical drain pipe of the outer wall through the overflow main pipe, the vertical drain pipe of the outer wall is connected with the external sewage discharging structure, and overflowed sewage is finally discharged through the vertical drain pipe, so that the diversion of the water is realized through the structure, the water pressure of the water is reduced, and the effect is excellent by combining measures of blocking the water.

The water backflow preventing measures for overflow dredging are insufficient, and when dealing with large water quantity, water backflow caused by insufficient overflow is still unavoidable, so that the structure for blocking water backflow is further arranged on the basis of the structure, and the measures adopted are different according to different uses of the sewer pipes, and the water backflow preventing measures are specifically as follows: the floor drain adopts a water-reflecting prevention floor drain which is of an existing mature structure, so that the description is omitted here; the upper end of the third sewer pipe is provided with a toilet check valve which is of an existing mature structure, so that the description is omitted here.

In addition to the above structure, the upper end of the first downcomer is provided with an adapter for connecting a drain pipe of the washing machine; specifically, the adapter comprises a main body part, a connecting part, a plugging part, a one-way valve and a plurality of sealing rings, wherein the connecting part is arranged at the side part of the upper end of the main body part and communicated with the main body part; compared with the traditional structure that the drain pipe of the washing machine is directly inserted into the sewer pipe, the upper port of the sewer pipe can be plugged by the plugging part of the adapter, odor is prevented from being strung out, the sealing ring sleeved at the lower end of the main body is sealed on one hand, the sealing ring is abutted against the inner wall of the first sewer pipe on the other hand, the connection firmness is improved, the drain pipe is prevented from being flushed by large water pressure, the check valve adopts a rebound structure, the one-way drainage to the first sewer pipe is realized, and the valve is rebound and closed when the drain pipe is not discharged.

The foregoing is a preferred embodiment of the present utility model. It should be noted that those skilled in the art may make several modifications without departing from the design principles and technical solutions of the present utility model, and these modifications should also be considered as the protection scope of the present utility model.
