Description

Drainage device

Technical Field

The utility model relates to the field of pipelines, in particular to a drainage device.

When the vertical pipe is used, the lower end of the vertical pipe is in butt joint communication with the floor drain, and the other end of the transverse pipe is used for butt joint of a drain pipe of the washing machine. Thus, although the drainage requirements can be satisfied, the drainage smoothness is low. When the sewage volume of discharging is very big, there is a large amount of sewage long-time gathering in the butt joint department of drain pipe and horizontal pipe, and sewage can be bigger to the butt joint department effort also, the condition that sewage oozes extremely easily appears in the butt joint department like this to can cause indoor pollution, this is liable to bring inconvenience for people's life. While it is now possible to use a sloped tube configuration at the inlet end of the transfer tube, the slope of the existing sloped tube is either too small or too large. When the inclination of the inclined pipe is too small, the smoothness of the drainage is still low, which still causes leakage. When the gradient of hang-up pipe is too big (mostly be vertical state, the gradient is 90 degrees promptly), dock at the drain pipe and back on the hang-up pipe, drain pipe butt joint department can extend upwards naturally, and the middle part of drain pipe can receive gravity effect whereabouts, the export height position of drain pipe is too big like this, the too big condition of middle part sagging extremely easily appears to easily influence the drainage of sewage, this is easy to remain a large amount of sewage in the drain pipe, and then easily deposit too much dirt in the drain pipe, this just easily leads to the life of drain pipe to shorten.

Therefore, it is necessary to redesign the structure of the transfer tube.
