Problems solved by technology

However, when the water enters the large curvature elbow, when there is garbage, sometimes it will vortex along the wall in the elbow to close the pipe, and the phenomenon of water plugging will occur, which will affect the stability of the water flow and the smooth flow of the pipe.

Embodiment Construction

[0011] Such as figure 1 It is a structural schematic diagram of the present invention, an elbow, including an elbow body 1, an arc-shaped segment 13 is formed between the inlet 11 and the outlet 12 of the elbow body 1, and the inner wall surface of the outer ring of the arc-shaped segment 13 is provided with a groove 14. A filter screen 15 is provided on the groove 14 to connect with the wall. The overall inner wall of the elbow body 1 is provided with guide threads 16 . When in use, when water and some garbage flow through the elbow, they flow out along the direction of the diversion thread. When there is too much garbage, the filter screen has limited bearing capacity. Under the impact of the water flow, the garbage and the filter screen are brought into the groove together. Ensure the smoothness of the elbow.

Abstract

The invention relates to the technical field of an auxiliary part of a drainage pipe and particularly relates to an elbow. The elbow comprises an elbow main body, wherein an arc-shaped section is arranged between an inlet and an outlet of the elbow main body; a groove is formed in the inner wall surface of an outer ring of the arc-shaped section, and is provided with a filter screen which is connected with the wall surface. According to the elbow, a water blocking phenomenon can be effectively prevented in a draining process, and the draining smoothness is guaranteed.

Description

technical field [0001] The invention relates to the technical field of auxiliary parts of drainage pipes, in particular to an elbow. Background technique [0002] In the existing toilet drainage system, the connecting pipe fittings between the drainage standpipe and the horizontal main pipe are either large curvature elbows or two 45-degree elbows, among which, the large-curvature elbow is generally more effective than the two 45-degree elbows. better. [0003] The existing large-curvature elbows have circular or elliptical inner surfaces and smooth surfaces. When the water in the drainage standpipe passes through the large curvature elbow, if the water can enter the horizontal main pipe smoothly, it is necessary to ensure that the phenomenon of water plugging is reduced, which is also the goal achieved. However, when the water enters the large curvature elbow, when there is garbage, it will sometimes vortex along the wall in the elbow to close the pipe, and a water plug p...
