Description

Technical Field

[0001] This application relates to the field of building drainage technology, and in particular to a lateral inlet and outlet tee. Background Technology

[0002] With social development, people's quality of life continues to improve, and their environmental awareness also increases accordingly, leading to higher requirements for living environments and buildings. In existing building drainage pipe systems, risers and horizontal branch pipes are mostly connected by tee fittings.

[0003] Most existing tee fittings connecting risers and horizontal branches are T-shaped with smooth inner surfaces.

[0004] The existing technical solutions mentioned above have the following drawbacks: when water enters the horizontal branch pipe of the existing tee fitting, it is easy to collide with the water flow in the riser, resulting in a decrease in drainage speed and an increase in noise. Utility Model Content

[0005] In order to increase drainage speed and reduce noise, this application provides a side-inlet drainage tee.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A lateral inlet and outlet tee includes a vertical pipe, which is vertically installed and connected to a horizontal pipe. A section of the horizontal pipe near the vertical pipe is bent to form an arc-shaped segment. One end of the arc-shaped segment of the horizontal pipe is connected to the vertical pipe along the tangent of the vertical pipe, so that the water flow in the horizontal pipe enters the vertical pipe in a certain arc-shaped swirling motion. A corrugated pipe is fitted on the vertical pipe.

[0008] By adopting the above technical solution, when water flows from the horizontal branch pipe into the vertical pipe through the horizontal pipe, the arc-shaped section of the horizontal pipe guides the water flow into the vertical pipe in a certain arc swirling motion, increasing the water flow velocity, reducing the noise generated by the water flow impact in the vertical pipe, and increasing the drainage speed. The corrugated pipe sleeved on the outer wall of the vertical pipe can improve the overall structural strength of the drainage tee, reduce the vibration amplitude of the vertical pipe, and reduce the resonance of the pipe wall caused by water flow impact. When the vertical pipe vibrates, the folds of the corrugated pipe rub and squeeze against each other, which can reduce the vibration energy of the vertical pipe. The sound waves enter the corrugated pipe and are reflected multiple times in the cavity between the corrugated pipe and the vertical pipe, which can reduce the guiding intensity, reduce the vibration transmission of the drainage tee, and reduce noise.

[0009] Optionally, a sleeve is fixedly connected inside the corrugated pipe, and the sleeve is fitted onto the vertical pipe so that the inner wall of the corrugated pipe is away from the vertical pipe.

[0010] By adopting the above technical solution, the inner wall of the corrugated pipe is moved away from the inner wall of the vertical pipe, forming an air damping layer between the corrugated pipe and the vertical pipe, thereby reducing noise.

[0011] Optionally, the height of the corrugated pipe gradually increases.

[0012] By adopting the above technical solution, the peak height of the bellows gradually increases, which can reduce the uniformity of the bellows wall and reduce the resonance noise of the bellows. The different peak heights of the bellows can reduce the occurrence of noise peaks at a single frequency and reduce noise.

[0013] Optionally, the corrugated pipe is made of HDPE material.

[0014] By adopting the above technical solution, the corrugated pipe made of HDPE material has sound absorption properties, which can absorb the sound waves generated by the water flow in the drain tee, reduce the sound transmission through the drain tee, and reduce noise.

[0015] Optionally, the end of the horizontal tube connected to the vertical tube is bent into an arc shape towards the lower end of the vertical tube.

[0016] By adopting the above technical solution, the water flow can be guided to spiral down along the inner wall of the vertical pipe, reducing the impact of the water flow from the horizontal pipe into the vertical pipe on the inner wall of the vertical pipe, reducing the noise generated by the vertical pipe, and increasing the drainage speed.

[0017] Optionally, a spiral protrusion is fixedly connected inside the vertical tube, and the spiral protrusion is spirally arranged.

[0018] By adopting the above technical solution, the spiral ridge can guide the water flow to spiral downward along the inner wall of the vertical pipe, which can reduce water turbulence, reduce the impact between the air column and the water flow, increase the drainage speed, and reduce noise.

[0019] Optionally, the inner diameter of the vertical tube gradually decreases from the top to the bottom.

[0020] By adopting the above technical solution, the inner diameter of the vertical pipe is gradually reduced, which can guide the water flow along the inner wall of the vertical pipe, and the auxiliary spiral ridges reduce water flow turbulence, increase drainage speed, and reduce noise.

[0021] Optionally, a guide pipe is fixedly connected inside the vertical pipe, and one end of the guide pipe is inclined inward into the vertical pipe.

[0022] By adopting the above technical solution, the guide pipe can guide the water flow into the vertical pipe to flow along the inner wall of the vertical pipe, reduce the noise caused by the rapid fall of the water flow in the vertical pipe hitting the water flow flowing out of the horizontal pipe, ensure smooth water flow in the horizontal pipe, and reduce noise.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up vertical pipes, horizontal pipes and corrugated pipes, the arc section of the horizontal pipe guides the water flow into the vertical pipe in a certain arc swirling motion, increasing the water flow velocity, reducing the noise generated by the water flow impact in the vertical pipe, increasing the drainage speed, reducing the vibration amplitude of the vertical pipe, reducing the resonance of the pipe wall caused by the water flow impact, and when the vertical pipe vibrates, the folds of the corrugated pipe rub and squeeze against each other, reducing the vibration transmission of the drainage tee and reducing noise;

[0025] 2. By setting the spiral protrusions, the spiral protrusions can guide the water flow to flow spirally downward along the inner wall of the vertical pipe, which can reduce water flow turbulence, reduce the impact between the air column and the water flow, increase the drainage speed, and reduce noise;

[0026] 3. By installing a guide pipe, the water flowing into the vertical pipe can be guided to flow along the inner wall of the vertical pipe, reducing the noise caused by the rapid fall of water in the vertical pipe hitting the water flowing out of the horizontal pipe, ensuring smooth water flow in the horizontal pipe and reducing noise.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a lateral inlet and outlet tee, referring to... Figure 1 and Figure 2 The drainage tee includes a vertical pipe 1, which is vertically installed. A horizontal pipe 2 is connected to a section of the vertical pipe 1 near its upper end. The section of the horizontal pipe 2 near the vertical pipe 1 is bent to form an arc-shaped segment. The central angle of the arc-shaped segment is 88.5° to 94.5°. In the preferred embodiment, the angle is 91.5°. The arc-shaped segment of the horizontal pipe 2 is connected to the vertical pipe 1 tangentially along the vertical pipe 1, so that the water flow in the horizontal pipe 2 enters the vertical pipe 1 in a certain arc-shaped swirling motion. The end of the horizontal pipe 2 near the vertical pipe 1 bends downward.

[0033] Reference Figure 1 and Figure 3A corrugated pipe 3 is fitted on the outer wall of the vertical pipe 1. The corrugated pipe 3 is arranged along the length direction of the vertical pipe 1. The height of the corrugated pipe 3 gradually increases from the top to the bottom. In this embodiment, the corrugated pipe 3 is a corrugated pipe 3 supported by HDPE material. A sleeve 31 is bonded to the inner wall of both ends of the corrugated pipe 3 along the length direction. The sleeve 31 is fitted on the vertical pipe 1, and the inner wall of the sleeve 31 is bonded to the vertical pipe 1, so that the inner wall of the corrugated pipe 3 is far away from the inner wall of the vertical pipe 1.

[0034] Reference Figure 3 The inner diameter of the section of the vertical tube 1 near its lower end gradually decreases. The inner wall of the section of the vertical tube 1 near its lower end is integrally formed with a spiral protrusion 4. The spiral protrusion 4 is spirally arranged along the length direction of the vertical tube 1. There are three spiral protrusion 4 arranged at intervals, and the three spiral protrusion 4 have the same spiral direction.

[0035] Reference Figure 3 A guide tube 5 is attached to the inner wall of the upper end of the vertical pipe 1. One end of the guide tube 5 is connected to the upper end of the vertical pipe 1, and the other end of the guide tube 5 extends into the guide tube 5. The section of the guide tube 5 extending into the vertical pipe 1 is bent into an arc shape, so that the end of the guide tube 5 extending into the vertical pipe 1 is inclined towards the inner wall of the vertical pipe 1.

[0036] When using this drainage tee, both ends of the riser 1 are connected to the riser of the drainage system, and the end of the horizontal pipe 2 away from the riser 1 is connected to the horizontal branch pipe of the drainage system. When water flows from the horizontal pipe 2 into the riser 1, the arc-shaped section of the horizontal pipe 2 guides the water flow into the riser 1 in a certain arc swirling motion, increasing the water flow velocity, reducing the noise generated by the water flow impact in the riser 1, and increasing the drainage speed. The corrugated pipe 3 fitted on the outer wall of the riser 1 can improve the overall structural strength of the drainage tee, reduce the vibration amplitude of the riser 1, and reduce the resonance of the pipe wall of the riser 1 caused by the water flow impact. When the riser 1 vibrates, the folds of the corrugated pipe 3 rub and squeeze against each other, which can reduce the vibration energy of the riser 1. The sound waves enter the corrugated pipe 3 and are reflected multiple times in the cavity between the corrugated pipe 3 and the riser 1, which can reduce the guiding intensity, reduce the vibration transmission of the drainage tee, and reduce noise.

[0037] The horizontal pipe 2 bends downward at the end closest to the vertical pipe 1, which can guide the water flow to spiral down along the inner wall of the vertical pipe 1, reduce the impact of the water flow from the horizontal pipe 2 into the vertical pipe 1 on the inner wall of the vertical pipe 1, reduce the noise generated by the vertical pipe 1, and increase the drainage speed.

[0038] The corrugated pipe 3, made of HDPE material, has sound-absorbing properties. It can absorb the sound waves generated by the water flow in the drain tee, reduce the sound transmission through the drain tee, and reduce noise.

[0039] The increasing height of the corrugated pipe 3 can reduce the uniformity of the pipe wall and reduce the resonance noise of the corrugated pipe 3. The different heights of the corrugated pipe 3 can reduce the occurrence of noise peaks at a single frequency and reduce noise.

[0040] A sleeve 31 is installed between the corrugated pipe 3 and the vertical pipe 1, so that the inner wall of the corrugated pipe 3 is far away from the inner wall of the vertical pipe 1, forming an air damping layer between the corrugated pipe 3 and the vertical pipe 1 to reduce noise.

[0041] The spiral ridge 4 can guide the water flow to spiral downward along the inner wall of the vertical pipe 1, which can reduce water turbulence, reduce the impact between the air column and the water flow, increase the drainage speed, and reduce noise.

[0042] The inner diameter of the vertical pipe 1 gradually decreases, which can guide the water flow along the inner wall of the vertical pipe 1, and assist the spiral protrusion 4 to reduce water flow turbulence, increase drainage speed, and reduce noise.

[0043] The guide pipe 5 can guide the water flow into the vertical pipe 1 to flow along the inner wall of the vertical pipe 1, reduce the noise caused by the rapid fall of the water flow in the vertical pipe 1 hitting the water flow flowing out of the horizontal pipe 2, ensure smooth water flow in the horizontal pipe 2, and reduce noise.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
