Description

Technical Field

[0001] The utility model belongs to the technical field of building drainage, and in particular relates to a novel interlayer drainage fitting. Background Art

[0002] In the field of building drainage, multiple P-type water traps are usually set under the floor for interlayer drainage. The P-type water trap includes two 45-degree elbows, in which a water column of a certain height (usually 50-100 mm) is formed. The water height of this part is called the water seal height, which can prevent various pollutants and small insects in the drainage pipe from entering the room. At present, most of the common water traps on the market have two problems. 1. The height is high, occupying the ceiling space of the bathroom; 2. The structure is not perfect, which becomes a blockage point for household drainage. Utility Model Content

[0003] The utility model aims to provide a novel interlayer drainage fitting to solve the above-mentioned technical problems.

[0004] In order to achieve the above-mentioned purpose, the specific technical scheme of a new type of interlayer drainage fitting of the utility model is as follows:

[0005] A novel interlayer drainage fitting comprises a first elbow, a second elbow, a third elbow and a straight pipe, wherein one end of the first elbow is connected to a round pipe reserved for a floor slab, and the other end is connected to the second elbow, the second elbow is connected to the third elbow, and the third elbow is connected to the straight pipe, the first elbow is a 45-degree elbow with a different diameter, the second elbow is a 90-degree elbow, and the third elbow is a 45-degree elbow.

[0006] Furthermore, the first elbow is an inserted elbow, and the first elbow is inserted into the second elbow and fixedly connected to one end of the second elbow.

[0007] Furthermore, the third elbow is an inserted elbow, and the third elbow is inserted into the other end of the second elbow and fixedly connected to the second elbow.

[0008] Furthermore, the connecting end of the first elbow and the second elbow, the second elbow, the third elbow and the straight pipe cross-section are all elliptical.

[0009] Furthermore, the first elbow is an interpolated elliptical reducing 45-degree elbow, the second elbow is an elliptical 90-degree elbow, the third elbow is an interpolated elliptical 45-degree elbow, and the straight pipe is an elliptical pipe.

[0010] Furthermore, the major diameter of the ellipse is parallel to the horizontal plane, and the minor diameter is perpendicular to the ground.

[0011] The utility model has the following advantages: the ... BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to better understand the purpose, structure and function of the utility model, a new type of interlayer drainage accessory of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 1-2 As shown, a novel interlayer drainage fitting of the utility model comprises a first elbow 1, a second elbow 2, a third elbow 3 and a straight pipe 4. One end of the first elbow 1 is connected to a round pipe reserved for the floor slab, and the other end is connected to the second elbow 2. The second elbow 2 is connected to the third elbow 3, and the third elbow 3 is connected to the straight pipe 4. The first elbow 1 is a 45-degree elbow with a different diameter, the second elbow 2 is a 90-degree elbow, and the third elbow 3 is a 45-degree elbow. Two 45-degree elbows are connected by a 90-degree elbow, which reduces the minimum height of the two 45-degree elbows, thereby reducing the overall height of the trap.

[0017] The first elbow 1 is an inserted elbow, which is inserted into the second elbow 2 and fixedly connected to one end of the second elbow 2 ; the third elbow 3 is an inserted elbow, which is inserted into the other end of the second elbow 2 and fixedly connected to the second elbow 2 .

[0018] In order to further reduce the height of the water trap, the connecting end of the first elbow 1 and the second elbow 2, the second elbow 2, the third elbow 3 and the straight pipe 4 are all elliptical in cross section. That is, the first elbow 1 is an interpolated elliptical reducing 45-degree elbow, the second elbow 2 is an elliptical 90-degree elbow, the third elbow 3 is an interpolated elliptical 45-degree elbow, and the straight pipe 4 is an elliptical pipe. The long diameter of the ellipse is parallel to the horizontal plane, and the short diameter is perpendicular to the ground, which further reduces the height of the water trap.

[0019] The new interlayer drainage fitting of the utility model connects two 45-degree elbows through a 90-degree elbow, which reduces the minimum height of the connection of the two 45-degree elbows. By setting the end of the first elbow 1, the second elbow 2, the third elbow 3 and the straight pipe 4 into an ellipse, the height of the water trap is further reduced, and the height space of the bathroom is increased; the drainage angle is increased, the anti-blocking and self-cleaning ability of the pipeline system is greatly improved, and the blockage problem of household drainage is unblocked. The drainage fitting of the utility model can be applied to various scenes that are limited by space and require water sealing function.
