Abstract

The utility model particularly relates to a drainage pipeline which comprises a horizontal branch pipe, a vertical pipe and a horizontal main pipe, wherein the horizontal branch pipe is connected with the vertical pipe by a pipeline connecting piece; and the vertical pipe is connected with the horizontal main pipe by an elbow. The drainage pipeline is characterized in that the pipeline connecting piece comprises a main pipe and a branch pipe, wherein the main pipe is vertical to the branch pipe; one part of the pipeline of the main pipe is in a frustum shape; the inner wall of the main pipe is provided with a guide vane which is formed by symmetrically arranging two arc-shaped plates along the inner wall of the main pipe by taking a longitudinal axis of the main pipe as bisector; the elbow comprises a water inlet and a water outlet, wherein the pipe diameter of the water inlet is not equal to the pipe diameter of the water outlet; and the elbow is characterized in that the cross section of the bending part between the water inlet and the water outlet takes on ellipse. The drainage pipeline has no phenomenon of backwater and blocking an air duct; and as the guide vane is arranged inside the pipeline connecting piece, a ventilation channel can be formed in the center of water flow flowing into the main pipe, the pressure of a pipe fitting can be prevented from being too high, and the drainage capacity of a drainage system can be improved.

Description

A kind of drainage pipe

Technical field:

The utility model belongs to the pipe drainage system, is specifically related to a kind of drainage pipe.

Background technique:

As everyone knows, drainage system has single standpipe to stretch top ventilation drainage system, two standpipe is stretched top ventilation drainage system, being connected of their standpipe and horizontal arm all adopts threeway to connect, in use, it is less that single standpipe is stretched top ventilation drainage system drainage capacity, and the draining hydraulic regime is relatively poor, in drainage procedure, when particularly having a large amount of water to discharge simultaneously, the water plug can take place in the pipeline and choke water phenomenon.Two standpipes stretch that top ventilation drainage system drainage capacity is bigger, and the draining hydraulic regime is better, but it is many to consume tubing, and it is bigger to take up room in the installation process, and it is longer that the time spent is installed.

Summary of the invention:

The utility model aims to provide a kind of drainage pipe that the water plug can not take place in the drainage procedure and choke water phenomenon.

The realization the technical solution of the utility model is: comprise horizontal arm, standpipe, horizontal main, horizontal arm connects standpipe by pipe joint, standpipe is connected by elbow with horizontal main, it is characterized in that pipe joint comprises the person in charge, arm, be responsible for be provided with vertical with arm, some is taper type for the pipeline of being responsible for, on the inwall of being responsible for guide vane is installed, to be two arc plates along the inwall of being responsible for and with the longitudinal axis of being responsible for be guide vane is symmetrical arranged, elbow comprises water intake, water outlet, the caliber of water intake and the caliber of water outlet are inequality, and the cross section of the crooked position between water intake and the water outlet is the egg circle.

Described egg circle is half laterally oval shape that combines with half vertical ellipse.

Laterally oval for major axis is a horizontal axis, minor axis is a pivotal axis; Vertically oval for major axis is a pivotal axis, minor axis is a horizontal axis.

Described pipe joint is threeway or four-way or five-way or six logical.

Horizontal main of the present utility model road elbow drain outlet is bigger than the water inlet inlet calibre, elbow uses larger radius of curvature and form of fracture to be the egg circle, like this when the standpipe current transfer the transverse tube current to, can not occur choking water phenomenon and air passageways is hindered phenomenon, be arranged on pipe joint and be responsible for the guide vane of output tube inwall, can make the middle of the stream that flows in the standpipe form air communication channel, making the draining current be the rotation shape in soil stack discharges, can control water in the drainage procedure, the flow direction of air, reach and prevent that pipe fitting pressure is excessive, the drainage capacity of raising drainage system.
