Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, specifically to a drainage riser connection structure. Background Technology

[0002] High-rise buildings typically use PVC (polyvinyl chloride) as drainage risers. PVC drainage risers are low in cost, lightweight, easy to install and maintain, and have strong pressure resistance and corrosion resistance, making them widely used in the drainage systems of mid- to high-rise buildings.

[0003] In related technologies, PVC drainage risers, during long-term use, experience significant impact from the vertical flow of water, which may contain gravel and foreign objects. This often leads to deformation or damage at the bend, causing water leakage. Furthermore, when the drainage riser becomes blocked, excessive pressure accumulates between the riser and the bend. Since the PVC bend is connected by adhesive, repairs can only be performed by sawing the PVC pipe, making pipe restoration difficult and increasing the risk of continued leakage.

[0004] Therefore, there is an urgent need for a drainage riser connection structure that can replace the original PVC bend to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage riser connection structure to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drainage riser connection structure, comprising:

[0008] A first drain pipe and a second drain pipe, wherein a bend is provided between the first drain pipe and the second drain pipe;

[0009] The bend is fitted with clamps at the connection points with the first drain pipe and the second drain pipe, respectively.

[0010] The first and second drain pipes are each made of PVC material independently.

[0011] The bend is made of cast iron.

[0012] The drainage riser connection structure of this scheme has at least the following technical advantages:

[0013] The drainage riser connection structure uses a cast iron elbow instead of the original PVC elbow, which effectively enhances the impact force generated by the vertical and rapid descent of water from the first drainage pipe in high-rise buildings. This prevents the elbow from deforming or breaking due to the impact, greatly improving its impact resistance and service life. Furthermore, the clamps facilitate the disassembly of the elbow, allowing for the cleaning of the first and second drainage pipes and preventing blockages. This ensures the stability and efficiency of the drainage system. The elbow is also easy to replace, improving the convenience and flexibility of replacement.

[0014] As a further improvement of this utility model, a rubber sealing sleeve is provided at the bottom of the clamp.

[0015] By installing a rubber sealing sleeve at the bottom of the clamp, the two ends of the bend can fit tightly with the first and second drain pipes respectively, filling the tiny gaps between the pipes and preventing water or sewage from leaking from the pipe connection, thus ensuring the sealing effect between the pipes. It also prevents the clamp from directly contacting the pipe, avoiding wear between the clamp and the pipe that could damage the pipe surface, effectively improving the sealing performance and safety of the pipe.

[0016] As a further improvement of this utility model, the bend is a W-shaped bend.

[0017] Because the bend is a W-shaped bend, the water flow channel is larger, reducing water flow resistance and enabling more efficient drainage. Especially in high-rise buildings where the water flow speed is high, the W-shaped bend can effectively prevent water blockage or backflow. It also facilitates the connection between the vertically installed first drainage pipe and the horizontally installed second drainage pipe, meets the impact resistance requirements of the drainage pipes in high-rise buildings, and ensures the stability of the drainage system.

[0018] As a further embodiment of this utility model, the included angle between the first drain pipe and the middle of the W-shaped bend is 45°.

[0019] As a further embodiment of this utility model, the included angle between the second drain pipe and the middle of the W-shaped bend is 45°.

[0020] Because the angle between the first drain pipe and the middle of the W-shaped bend is 45°, and the angle between the second drain pipe and the middle of the W-shaped bend is also 45°, the bend is inclined at 45° between the first and second drain pipes. Compared with the traditional L-shaped bend, this avoids the excessive impact force of the vertical water flow, which could cause deformation or damage to the bend. This further improves the impact resistance of the bend and ensures the stability and reliability of the drainage system.

[0021] As a further improvement of this utility model, the clamp is made of flexible stainless steel.

[0022] Because the clamps are made of flexible stainless steel, they have excellent corrosion resistance and can resist the erosion of water and moisture, meeting the purpose of use in humid environments and ensuring the service life of the clamps. They can also be quickly tightened and loosened for the installation or disassembly of bends, and are applicable to pipes of different diameters, improving the versatility and flexibility of the clamps.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] like Figure 1 The present invention provides a drainage riser connection structure, comprising: a first drainage pipe 101 and a second drainage pipe 102, wherein a bend 103 is provided between the first drainage pipe 101 and the second drainage pipe 102; clamps 104 are respectively provided at the connection points of the bend 103 with the first drainage pipe 101 and the second drainage pipe 102; the first drainage pipe 101 and the second drainage pipe 102 are each independently made of PVC material; the bend 103 is made of cast iron material.

[0034] Specifically, the drainage riser connection structure uses a cast iron elbow 103 instead of the original PVC elbow, which effectively enhances the impact force generated by the vertical and rapid fall of water from the first drainage pipe 101 on the elbow 103 when draining water from the first drainage pipe 101 in high-rise buildings. This prevents the elbow 103 from deforming or breaking due to the impact force, greatly improving the impact resistance and service life of the elbow 103. Furthermore, the clamp 105 allows for easy disassembly of the elbow 103 to clean the first drainage pipe 101 and the second drainage pipe 102, preventing blockage and ensuring the stability and efficiency of the drainage system. At the same time, the elbow 103 is easy to replace, improving the convenience and flexibility of elbow 103 replacement.

[0035] like Figure 1 As shown, a rubber sealing sleeve 105 is provided at the bottom of the clamp 104.

[0036] Specifically, by setting a rubber sealing sleeve 105 at the bottom of the clamp 104, the two ends of the bend 103 can be tightly fitted to the first drain pipe 101 and the second drain pipe 102 respectively, filling the tiny gaps between the pipes, preventing water or sewage from leaking from the pipe connection, and ensuring the sealing effect between the pipes; it can also prevent the clamp 104 from directly contacting the pipe, avoiding wear between the clamp 104 and the pipe that could damage the pipe surface, effectively improving the sealing performance and safety of the pipe.

[0037] According to an embodiment of the present invention, the bend 103 is a W-shaped bend.

[0038] Specifically, since the bend 103 is a W-shaped bend, the water flow channel is larger, the water flow resistance is reduced, and the drainage is more efficient. Especially in high-rise buildings, where the water flow speed is relatively fast, the W-shaped bend 103 can effectively prevent water flow blockage or backflow. It also facilitates the connection between the vertically installed first drainage pipe 101 and the horizontally installed second drainage pipe 102, meets the impact resistance requirements of the drainage pipes in high-rise buildings, and ensures the stability of the drainage system.

[0039] Furthermore, the included angle between the first drain pipe 101 and the middle of the W-shaped bend is 45°; the included angle between the second drain pipe 102 and the middle of the W-shaped bend is 45°.

[0040] Specifically, since the angle between the first drain pipe 101 and the middle of the W-shaped bend is 45°, and the angle between the second drain pipe 102 and the middle of the W-shaped bend is also 45°, the bend 103 is inclined at 45° between the first drain pipe 101 and the second drain pipe 102. Compared with the traditional L-shaped bend, this avoids excessive impact force from the vertical water flow, which could cause deformation or damage to the bend 103, further improving the impact resistance of the bend 103 and ensuring the stability and reliability of the drainage system.

[0041] It should also be noted that the clamp 104 is made of flexible stainless steel.

[0042] Specifically, since the clamp 104 is made of flexible stainless steel, it has good corrosion resistance and can resist the erosion of water and moisture, thus meeting the purpose of use in humid environments and ensuring the service life of the clamp 104. It can also be quickly tightened and loosened to install or disassemble the bend 103, and can be used for pipes of different diameters, improving the versatility and flexibility of the clamp 104.

[0043] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
