Description

Oval water tee bend pipe fitting that follows

Technical Field

The utility model relates to a PVC drain pipe technical field, concretely relates to oval following water tee bend pipe fitting.

Background

The downstream tee joint is a pipe fitting in a drainage pipeline and is used for vertically connecting a branch pipe with a main pipe. Although the branch pipes are vertically connected, the joints of the branch pipes entering the main pipe are not vertically intersected but are connected by a small section of circular arc along the flowing direction of water, so that the water of the branch pipes smoothly flows to the main pipe, and the small section of circular arc plays a role in following the water. The bell mouth of a common downstream tee pipe fitting is circular.

In the secondary reconstruction of indoor drainage pipeline systems such as a floor drain opening, a platform basin drain opening displacement and the like, the use of a common downstream tee joint has the following defects: 1) the grooving is deep, and the construction is inconvenient; 2) the water flow of the trunk and branch pipes is strongly intersected, and the noise is large; 3) because the three-way pipe fitting of indoor secondary reconstruction is used for connecting the horizontal pipe, the water flow of the main pipe has the possibility of flowing into the branch pipe; 4) the erosion of branch pipe water flow to the pipe wall is serious.

1) the three-way pipe fitting adopts an elliptical flat pipe structure, and is shallow in grooving during laying, small in damage to a structural floor layer and low in construction difficulty;

2) the arrangement of the drainage baffle plate can avoid the cross flow of water flow of the main pipe to the branch pipe, and meanwhile, the drainage baffle plate can change the water flow direction of the branch pipe, so that the included angle between the water flow and the pipe wall is smaller when the water flow impacts the pipe wall, and the impact force on the pipe wall is reduced.

3) The rigidity near the structure excitation point is enhanced by the arrangement of the reinforcing ribs, so that the structure vibration is reduced, the sound source power is reduced, and the surface is uneven by the reinforcing ribs to cause sound wave scattering to cause sound energy attenuation in the transmission process.

Detailed Description

The invention is further described with reference to the accompanying drawings.

As shown in fig. 1-2, an elliptical downstream three-way pipe fitting is made of plastic and is formed in one step by using an injection molding process, and comprises a first bell mouth 1, a reinforcing rib 2, a third bell mouth 3, a second bell mouth 4, a drainage baffle 5, a downstream arc 6, a drainage elliptical main pipe 7 and a drainage elliptical branch pipe 8.

A drainage baffle 5 is arranged at the top of the inner part of the joint of the drainage elliptical main pipe 7 and the drainage elliptical branch pipe 8, and the drainage baffle 5 is arranged in a downward inclination manner along the drainage direction of the drainage elliptical main pipe 7; the inner bottom position of the joint of the drainage elliptical main pipe 7 and the drainage elliptical branch pipe 8 is provided with a downstream arc 6, the outer wall of the drainage elliptical main pipe 7 is provided with a reinforcing rib 2 for noise reduction, and the reinforcing rib 2 is arranged at the position opposite to the drainage elliptical branch pipe 8.

A first bellmouth 1 is arranged at the water inlet position of the water drainage elliptical main pipe 7, a third bellmouth 3 is arranged at the water outlet position of the water drainage elliptical main pipe 7, and a second bellmouth 4 is arranged at the water inlet position of the water drainage elliptical branch pipe 8; the first bell mouth 1, the second bell mouth 4 and the third bell mouth 3 are arranged in the same diameter or different diameters.

The working principle is as follows:

when the drainage flow is small, water flows at the bottom of the drainage elliptical branch pipe, the drainage baffle does not work, the water flow of the drainage elliptical main pipe and the drainage elliptical branch pipe is not strongly intersected, and the noise is small. When drainage flow is big, the oval main pipe rivers of drainage and the oval branch pipe rivers of drainage produce obvious reposition of redundant personnel through the drainage baffle, reduce rivers strength of crossing, simultaneously, because the existence of the strengthening rib of making an uproar falls in the outer pipe wall, branch pipe rivers impact the pipe wall and produce the vibration less to holistic noise has been reduced. In addition, the existence of the baffle also changes the original streamline of the water flow of the water discharge oval main pipe, and compared with a common downstream three-way pipe, the condition that the water flow of the water discharge oval main pipe flows to the second socket in a cross flow mode is avoided, and meanwhile, the phenomenon that the downstream arc generates extra noise under the impact of the water flow of the water discharge oval main pipe is also avoided. The drainage baffle also changes the flow line of the water flow of the drainage elliptical branch pipe, so that the acute angle between the drainage elliptical branch pipe and the pipe wall is smaller when the drainage elliptical branch pipe impacts the pipe wall, the impact force on the pipe wall is reduced, and the noise reduction reinforcing ribs increase the strength of the pipe wall, thereby enhancing the erosion resistance of the pipe fitting.
