DETAILED DESCRIPTION

[0036] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figure 1-5 As shown, a combiner of the present invention comprises a pipe body 1 , in which a first channel 101 and a second channel 102 are arranged.

[0038] The two ends of the first channel 101 are used to be connected to a main pipeline, such as a main drainage pipe in a drainage system.

[0039] One end of the second channel 102 is connected to the first channel 101, and the other end is connected to a branch pipe, such as each branch drainage pipe connected to a floor drain and other components in a drainage system, so as to merge the medium in the branch pipe and flow into the main pipe.

[0040] like Figure 1 As shown, the second channel 102 includes a confluence section 1021 and a connecting section 1023, wherein one end of the confluence section 1021 is connected to the middle position of the first channel 101, and its center line is inclined to the center line of the first channel 101, and the confluence section 1021 is inclined toward the direction close to the inlet end of the first channel 101, and the angle is preferably 10-60 degrees. When the medium flows in the first channel 101, it is not easy to flow into the confluence section 1021, thereby preventing the medium in the main pipeline from flowing back into the branch pipeline.

[0041] The multiple pipes in the current common piping system are usually arranged in parallel or vertically, and the branch pipes and the main pipes are usually arranged vertically. One end of the connecting section 1023 is connected to the end of the confluence section 1021 away from the first channel 101, and its center line is perpendicular to the center line of the first channel 101, so that the connecting section 1023 can be directly connected to the pipe perpendicular to the first channel 101 without using a connecting elbow, making the present combiner more suitable for the current common piping system.

[0042] The second channel 102 also includes a flat flow section 1022, and both ends of the flat flow section 1022 are respectively connected to the confluence section 1021 and the connecting section 1023; the smaller the angle between the confluence section 1021 and the first channel 101, the better the backflow and confluence effects, and the connecting section 1023 is perpendicular to the first channel 101, therefore, the angle between the connecting section 1023 and the confluence section 1021 is large, and the flat flow section 1022 can buffer the medium in the second channel 102 to reduce the impact of the medium on the pipeline body 1 and allow the media in the two medium channels to better merge and converge.

[0043] In order to improve the flow uniformity of the medium, it is preferred that the center line of the confluence section 1021, the center line of the horizontal flow section 1022, the center line of the connecting section 1023 and the center line of the first channel 101 are located in the same plane; and in order to improve the stroke of the second channel 102 and achieve a better buffering effect, it is preferred that the center line of the horizontal flow section 1022 is parallel to the center line of the first channel 101.

[0044] like Figure 1 , Figure 3 and Figure 5 As shown, a first connecting groove 104 is provided at both ends of the first channel 101, the inner diameter of the first connecting groove 104 is larger than the inner diameter of the first channel 101, and is coaxially arranged therewith; a second connecting groove 105 is provided at the end of the connecting section 1023 away from the first channel 101, the inner diameter of the second connecting groove 105 is larger than the inner diameter of the connecting section 1023, and is coaxially arranged therewith; thereby facilitating the insertion of the pipes in the piping system into the first channel 101 and the second channel 102, and sealing against the first connecting groove 104 or the second connecting groove 105, so as to improve the connection sealing performance of the combiner.

[0045] like Figure 1 As shown, the second channel 102 is provided with multiple bends, which will cause the pipeline body 1 to be inconvenient to process and maintain. In order to solve this problem, it is preferred to set the pipeline body 1 as a split structure.

[0046] The pipeline body 1 includes a first tube body 11 and a second tube body 12. The first channel 101 includes an input section 1011 and an output section 1012. The input section 1011, the horizontal flow section 1022 and the connecting section 1023 are opened in the first tube body 11; the output section 1012 and the confluence section 1021 are opened in the second tube body 12; the second tube body 12 is detachably fixed on the first tube body 11 and is sealed therewith.

[0047] Specifically, Figure 2 As shown, the first pipe body 11 includes an input pipe 111, a cover plate 112 and a connecting pipe 113, wherein the input section 1011 is opened in the input pipe 111; the cover plate 112 is integrally formed on the outer side of the input pipe 111, and is enclosed therewith to form a horizontal flow section 1022; the connecting pipe 113 is integrally formed on a side of the cover plate 112 away from the input pipe 111, and is located at an end thereof away from the second pipe body 12, and the connecting section 1023 is opened in the connecting pipe 113; the input pipe 111, the cover plate 112 and the connecting pipe 113 are combined to form the input section 1011, the horizontal flow section 1022 and the connecting section 1023 which are convenient for processing and maintenance.

[0048] like Figure 4 As shown, the second tube body 12 includes an output pipe 121 and an expansion plate 122. The expansion plate 122 is arranged on the outside of the output pipe 121 near one end of the first tube body 11. The expansion plate 122 and the output pipe 121 are integrally formed and continuously arranged, and are enclosed therewith to form an output section 1012 and a confluence section 1021, which is also convenient for processing and maintenance. The second tube body 12 and the first tube body 11 are spliced ​​together to form the first channel 101 and the second channel 102, and when the two are disassembled, it is convenient to clean and maintain the interior of the first channel 101 and the second channel 102.

[0049] It is preferred that the first tube body 11 and the second tube body 12 are connected by plugging; specifically, Figure 3 As shown, a card groove 103 is provided inside the second tube body 12 near one end of the first tube body 11, and one end of the first tube body 11 near the second tube body 12 is sealed in the card groove 103. The first tube body 11 is used to connect the inlet end of the main pipeline. After being inserted into the second tube body 12, the impact of the medium on the connection gap between the first tube body 11 and the second tube body 12 can be reduced, thereby improving the connection sealing between the first tube body 11 and the second tube body 12.

[0050] The working principle of a combiner of the utility model is as follows:

[0051] like Figure 1As shown, the left end of the first channel 101 is connected to the entrance end of the main pipeline, the right end of the first channel 101 is connected to the discharge end of the main pipeline, and the upper end of the connecting section 1023 is connected to the entrance end of the branch pipeline. When the medium in the two pipelines flows, the effect of allowing the medium in the second channel 102 to merge into the medium in the first channel 101 can be achieved; at the same time, since the confluence section 1021 is inclined with the first channel 101, the medium in the first channel 101 will not flow back into the second channel 102, and the connecting section 1023 is perpendicular to the first channel 101, which is more suitable for the current common situation where the main pipeline and the branch pipeline are perpendicular, thereby improving the versatility of the present combiner.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
