Description

Technical Field

[0001] This utility model relates to the field of water pipe technology, specifically a large arc-shaped water pipe that allows for smooth water flow. Background Technology

[0002] When water flows through a right-angle bend, its flow direction changes abruptly, causing a significant change in momentum within a short period. Due to the principle of momentum conservation, this change generates a corresponding impact force, resulting in a large impact at the right-angle bend. As water flows through the pipe, its pressure fluctuates with changes in flow velocity. At the right-angle bend, the sudden change in velocity causes a sharp increase or decrease in local pressure. This pressure fluctuation also increases the impact of the water flow on the bend. Therefore, the sealing structure at the bend of traditional pure right-angle bends is prone to premature failure over time. Structural improvements are needed to reduce the impact of water flow on the bend. Therefore, we propose a large-arc bend water pipe with smooth water flow. Utility Model Content

[0003] The purpose of this invention is to provide a large arc-shaped water pipe that allows for smooth water flow, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a large arc-shaped water pipe with smooth water flow, comprising a drain pipe, an elbow structure, and a drainage bend connected in sequence. The elbow structure includes an L-shaped elbow, with a connector A connected to one side of the bottom of the L-shaped elbow, and a branch pipe connector connected to one side of the vertical end of the L-shaped elbow. The output end of the branch pipe connector is connected to the branch drainage pipe, and the output section of the branch drainage pipe is connected to the drainage bend.

[0005] Furthermore, the drainage bend includes a horizontal short pipe, a vertical pipe, and a horizontal long pipe connected in sequence, with a connector B connected to the top circumferential surface of the horizontal long pipe.

[0006] Furthermore, the branch drainage pipes are folded pipes, and the branch pipe joints are beveled joints with the beveled surface facing downwards.

[0007] Furthermore, the angle between the branch pipe joint and the vertical end of the L-shaped elbow is set to °. The branch drainage pipe includes an inclined pipe and a vertical pipe. The inclined pipe of the branch drainage pipe is connected to the branch pipe joint in a concentric circle, and the vertical pipe of the branch drainage pipe is connected to the joint B in a concentric circle.

[0008] Furthermore, the horizontal short pipes and horizontal long pipes are arranged parallel to each other vertically, and the vertical pipes are all arranged perpendicular to the horizontal short pipes and horizontal long pipes.

[0009] Furthermore, the bottom end of the L-shaped elbow has an integrally formed rounded chamfer on one side.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The technical solution of this application, by combining the elbow structure with the drainage elbow, changes the original traditional pure right-angle elbow structure into a pipe structure with three buffer arcs, which can reduce the impact force of water flow on the elbow and extend the service life of the pipe elbow seal. The position design of the three buffer arcs is ingenious and does not affect the smoothness of drainage.

[0012] 2. The technical solution of this application adds a set of drainage channels on one side of the elbow structure, which consists of a branch pipe joint and a branch drainage pipe. Even if the connection between the elbow structure and the drainage bend is blocked, the drainage can still be smoothly discharged from the branch drainage pipe, thus achieving the effect of dual-channel drainage.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1, such as Figure 1-3 As shown, this utility model provides a technical solution: a large arc bend water pipe with smooth water flow, including a drain pipe 1, an elbow structure 2 and a drainage bend 3 connected in sequence. The elbow structure 2 includes an L-shaped elbow 201. A connector A202 is connected to one side of the bottom of the L-shaped elbow 201. A branch pipe connector 203 is connected to one side of the vertical end of the L-shaped elbow 201. The output end of the branch pipe connector 203 is connected to a branch drainage pipe 4. The output section of the branch drainage pipe 4 is connected to the drainage bend 3.

[0020] In one specific embodiment of this utility model, the top end of the L-shaped elbow 201 is heat-fused to the bottom end of the drain pipe 1, the inlet end of the horizontal short pipe 301 is heat-fused to the connector A202, the inlet end of the branch drain pipe 4 is heat-fused to the branch pipe connector 203, and the outlet end of the branch drain pipe 4 is heat-fused to the connector B304. During normal drainage, since the inlet of the branch pipe connector 203 is located on the vertical surface of the L-shaped elbow 201, most of the water will flow along the L-shaped elbow 201 and connector A202 into the drain bend 3 for drainage. When the horizontal short pipe 301 and vertical pipe 302 are blocked, the water level will rise until the water can enter the horizontal long pipe 303 from the branch pipe joint 203, the branch drain pipe 4, and the joint B304 for drainage. Even if the connection between the elbow structure 2 and the drainage bend 3 is blocked, the water can still drain smoothly from the branch drain pipe, achieving the effect of secondary drainage. During normal drainage, the water will pass through the elbow structure 2 and the drainage bend 3. The pipe structure with three buffer arcs can reduce the impact of water flow on the elbow and extend the service life of the pipe elbow seal.

[0021] In the preferred technical solution, the drainage bend 3 includes a horizontal short pipe 301, a vertical pipe 302, and a horizontal long pipe 303 connected in sequence. The top circumferential surface of the horizontal long pipe 303 is connected to a connector B304. The horizontal short pipe 301 and the horizontal long pipe 303 are arranged parallel to each other vertically. The vertical pipes 302 are all arranged perpendicular to the horizontal short pipe 301 and the horizontal long pipe 303. The bend structure 2 and the drainage bend 3 form a pipe structure with three buffer arcs, which can reduce the impact force of water flow on the bend and extend the service life of the pipe bend seal.

[0022] In the preferred technical solution, the branch drainage pipe 4 is a folded pipe, and the branch pipe joint 203 is an oblique joint. The oblique surface of the branch pipe joint 203 is set downwards, and the angle between the branch pipe joint 203 and the vertical end of the L-shaped elbow 201 is set to 45°. The branch drainage pipe 4 includes an oblique pipe and a vertical pipe. The oblique pipe of the branch drainage pipe 4 is connected to the branch pipe joint 203 in a concentric circle, and the vertical pipe of the branch drainage pipe 4 is connected to the joint B304 in a concentric circle. The oblique setting of the branch pipe joint 203 is consistent with the folded shape of the branch drainage pipe 4. The oblique channel is conducive to accelerating the drainage efficiency.

[0023] In the preferred technical solution, the bottom side of the L-shaped elbow 201 is integrally formed with a rounded chamfer 204, which serves to buffer and guide water flow and foreign objects through the corner.

[0024] In summary: the pipe structure formed by the elbow structure 2 and the drainage bend 3 creates three buffer arcs. The water flow passes through three buffer arc inflection points, which reduces the impact force of the water flow on the elbow and extends the service life of the pipe elbow seal. When the L-shaped elbow 201, joint A202, horizontal short pipe 301, and vertical pipe 302 are blocked, the water level will rise until the water can enter the horizontal long pipe 303 from the branch pipe joint 203, branch drain pipe 4, and joint B304 for drainage. Even if the connection between the elbow structure 2 and the drainage bend 3 is blocked, the water can still drain smoothly from the branch drain pipe, achieving the effect of secondary drainage.
