Abstract

The invention relates to a drain pipe joint, which consists of a guide chamber, a transverse branch pipe and guide vanes. The guide chamber is a columnar cavity; 3 to 4 guide vanes are spirally distributed in the guide chamber; the rotating directions of the transverse branch pipe and the guide vanes are consistent; and the guide vanes are willow-leaf shaped, the vane surface is a concave curved surface, and the distance between the upper and lower guide vanes positioned in the guide chamber accounts for 70 to 95 percent of the length of the drain pipe joint. The drain pipe joint is characterized in that the joint between the transverse branch pipe and the guide chamber is provided with a transverse branch pipe guide baffle plate, and the transverse branch pipe is rotationally connected along the outer wall of the guide chamber. The provided drain pipe joint can keep vertical communication with the air in the drain pipe, and has good exhaust and drainage effects.

Description

A kind of drain connection

Technical field

The present invention relates to a kind of liquid drainage means, the piecing devices of particularly this liquid waste pipe.

Background technique

Existing drain connection can be divided into threeway and four-way, all is horizontal arm is directly carried out draining with UNICOM of diversion chamber, and owing in the process of draining, ducted air is subjected to the influence of overflow can't discharge conduit, causes impeded drainage.

Summary of the invention

Purpose of the present invention is intended to overcome the defective of prior art, provides a kind of and can keep the upper and lower perforation of draining inner air tube, and exhaust is good, the drain connection that drainage effect is good.

Drain connection of the present invention, constitute by diversion chamber, horizontal arm, guide vane, diversion chamber is the column cavity, and the upper end of diversion chamber is inlet, and the other end is outlet, diversion chamber's internal spiral is distributed with 3-4 sheet guide vane, the angle of guide vane and horizontal plane is the 10-80 degree, and guide vane and diversion chamber are integral structure, and at least one horizontal arm is positioned at the top of diversion chamber, horizontal arm is consistent with the sense of rotation of guide vane, and UNICOM with it.

Described drain connection, guide vane are wicker leaf shape, and the blade face is a concave curved surface.Distance between upper and lower two guide vanes in diversion chamber accounts for the 70-95% of drain connection length.

Described drain connection has horizontal arm water guide baffle plate at horizontal arm and diversion chamber connection.Horizontal arm water guide baffle plate and diversion chamber's locular wall are 5-80 degree angle.When horizontal arm was two, two horizontal arms were positioned at same plane, and were 90-180 degree angle each other.Horizontal arm is rotatably connected along diversion chamber's outer wall.

Drain connection of the present invention; can connect the three-way pipe or the four-way pipe of waste pipe; angle between two horizontal arms of four-way pipe is the 90-180 degree; rectangular four-way; it also can be straight angle four-way; can be used as the special-purpose connection set of single standpipe drainage pipe in the construction engineering; when water flows down from the top; enter into diversion chamber from inlet; last guide vane through the spiral distribution; following guide vane and middle guide vane draw cloth; guide vane is wicker leaf shape, and the blade face all is indent streamline curved surface, and this curved surface and water advance to match under the gravity rotating flow; make the centrifugal cyclone of current attached wall of formation in diversion chamber and in the honeycomb duct pipeline; rotate from outlet again and flow into waste pipe, the air in the waste pipe also can be discharged along vacancy in centrifugal, guarantee that the air in the waste pipe is protected up/down perforation all the time; thereby reach the effect of steady pipe internal pressure; improved the unobstructed ability of draining of waste pipe, current are attached wall eddy flow under the effect of gravity, has improved drain discharge.Last guide vane is positioned at the top of horizontal arm water conservancy diversion inlet; clog the draining of horizontal arm with the water resistance that flows down above preventing; further the draining of the horizontal arm of protection is unobstructed; the water conservancy diversion inlet of horizontal arm flows into diversion chamber in counterclockwise pin mode; its sense of rotation is consistent with guide vane; flow into diversion chamber with attached wall rotation mode when making horizontal arm current flow into diversion chamber, the attached wall eddy flow of this kind can not produce overflow, thereby has avoided the obstruction of the overflow of horizontal arm direct current generation to the waste pipe air.When horizontal arm current flow into diversion chamber, the horizontal arm water guide baffle plate of current on horizontal arm flows into diversion chamber, horizontal arm water guide baffle plate and water conservancy diversion locular wall are miter angle, current can be imported the locular wall that side direction flows into diversion chamber on the one hand, connect with guide vane on the locular wall, on the other hand, the relative aperture of the horizontal arm water conservancy diversion inlet horizontal arm water guide baffle plate of flowing through is big, form funnel-like, quicken the rotation flow velocity of water.

Drain connection of the present invention, rational in infrastructure, can better keep the upper and lower perforation of draining inner air tube, exhaust is good, and drainage effect is good.
