Description

Technical Field

[0001] The present application relates to the technical field of water supply and drainage, and in particular to a flexible socket-and-spigot silent drainage pipe fitting with a large arc bend. Background Art

[0002] In the water supply and drainage system, the elbow is a pipe fitting that changes the direction of the pipeline. It is a commonly used connecting pipe fitting in the installation of the pipeline system. As an accessory for adjusting the layout direction of the pipeline according to the needs of the pipeline system, it plays an extremely important role.

[0003] Existing elbow fittings, due to the long distances of the piping system, are subject to high-speed water flow, which can cause significant impact on the elbows. This impact can easily damage elbow fittings at the bends, compromising the safety of the piping system and causing water leaks. Furthermore, replacing damaged elbow fittings is extremely cumbersome. Therefore, there is an urgent need for an elbow fitting that can withstand the impact of high-speed water flow and reduce noise to address these issues.

[0004] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art known to those skilled in the art. Summary of the Invention

[0005] In view of the above problems, a flexible socket-and-spigot silent drainage pipe fitting with a large arc bend is provided. The flexible socket-and-spigot silent drainage pipe fitting with a large arc bend can reduce the impact of water flow on the elbow, avoid damage to the elbow, and at the same time achieve the purpose of sound insulation and noise reduction.

[0006] Specifically, the present application provides a flexible socket-and-spigot silent drainage pipe fitting with a large arc bend, comprising an elbow, a water inlet joint and a drainage joint respectively arranged at both ends of the elbow; a rotating blade is provided in the cavity of the elbow near the water inlet joint, and the rotating blade is used to rotate accordingly under the impact of the water flow; a buffer plate is provided at the bottom of the inner wall of the elbow near the drainage joint.

[0008] Optionally, the rotating blades and the buffer plates are both in the shape of arc-shaped sheets.

[0009] Optionally, the diameter of the end of the elbow connected to the drainage joint is larger than the diameter of the end of the elbow connected to the water inlet joint.

[0010] Optionally, a bracket is provided at the bottom of the outer wall of the elbow, and the bracket includes a support plate and a support column provided on the support plate.

[0013] The flexible socket-and-spigot silent drainage pipe fitting of the present application has a large arc bend, so that the water flow first consumes part of its kinetic energy through the rotation of the rotating blades in the elbow, and then consumes part of its kinetic energy again through the buffering effect of the buffer plate. Through double energy consumption, the energy of the water flow is greatly weakened, thereby reducing the impact of the water flow on the elbow and avoiding damage to the elbow. In addition, by consuming the kinetic energy of the water flow, the purpose of silencing and reducing noise can also be achieved.

[0020] Figure 1 This is a schematic structural diagram of a flexible socket-and-spigot silent drainage pipe with a large arc bend in an embodiment of the present application, as shown in FIG. Figure 1 As shown, and reference Figure 2 and Figure 3 The present invention provides a flexible, socket-and-spigot silent drainage pipe fitting with a large arc bend, comprising an elbow 110, an inlet connector 120, and a drain connector 130, respectively connected to the ends of the elbow 110. Rotating blades 141 are disposed within the cavity of the elbow 110 near the inlet connector 120. Rotating blades 141 are configured to rotate about the direction of the water flow under the impact of the water flow. A buffer plate 150 is disposed at the bottom of the inner wall of the elbow 110 near the drain connector 130.

[0021] In the large-arc bend of the flexible socket-and-spigot silent drainage pipe fitting of the embodiment of the present application, water flows into the elbow 110 through the water inlet joint 120, and the water impacts the rotating blades 141, causing the rotating blades 141 to rotate and continue to flow downward. The water then flows onto the buffer plate 150 and is finally discharged through the drainage joint 130. In the large-arc bend of the flexible socket-and-spigot silent drainage pipe fitting of the present application, the water first consumes a portion of its kinetic energy through the rotation of the rotating blades 141 in the elbow 110, and then consumes another portion of its kinetic energy through the buffering effect of the buffer plate 150. This double energy consumption greatly weakens the energy of the water flow, thereby reducing the impact of the water flow on the elbow 110 and preventing damage to the elbow 110. Furthermore, by consuming the kinetic energy of the water, the water also achieves the purpose of silencing and reducing noise.

[0022] In some embodiments of the present application, Figure 3 As shown, the flexible socket-and-spigot silent drainage pipe fitting with a large arc bend also includes a rotating column 142 and a support frame 143. The rotating blades 141 are evenly distributed on the outer wall of the rotating column 142 around the axis of the rotating column 142. The support frame 143 is connected to the inner wall of the elbow 110 to support the rotating column 142, which is arranged along the direction of water flow.

[0023] In the embodiment of the present application, water flow impacts rotating blades 141, which drive rotating column 142 to rotate within support frame 143. Support frame 143 includes multiple support bars evenly distributed on the inner wall of elbow 110. The middle portions of the multiple support bars are provided with rotation grooves, into which rotating column 142 is inserted.

[0024] In some embodiments of the present application, Figure 3 As shown, the rotating blades 141 and the buffer plate 150 are both in the shape of arcuate sheets. In the embodiment of the present application, the arcuate sheet-shaped rotating blades 141 and the buffer plate 150 can reduce the impact of the water flow when the water flow reaches the rotating blades 141 and the buffer plate 150.

[0025] In some embodiments of the present application, Figures 1 to 3 As shown, the diameter of the elbow 110 at one end connected to the drain connector 130 is larger than the diameter of the elbow 110 at one end connected to the water inlet connector 120. In this embodiment of the present application, since the diameter of the drain end of the elbow 110 is larger than the diameter of the water inlet end, the water flow is smoother and blockage in the elbow 110 can be avoided.

[0026] In some embodiments of the present application, Figures 1 to 3 As shown, a bracket 160 is provided at the bottom of the outer wall of the elbow 110, and the bracket 160 includes a support plate 161 and a support column 162 provided on the support plate 161. In the embodiment of the present application, the bracket 160 can support the elbow 110 and ensure the stability of the elbow 110.

[0027] In some embodiments of the present application, Figure 2 As shown, an inspection port 170 is provided at a corresponding position on the elbow 110. Inspection port 170 is cylindrical in shape. A blocking block 181 is provided within inspection port 170, and an inspection cover 182 is threadedly connected to inspection port 170. A retaining groove 171 is provided on the inner wall of inspection port 170, and a retaining boss 1811 is provided on the outer wall of blocking block 181 to match the retaining groove 171.

[0028] In this embodiment of the present application, the outer wall of inspection port 170 is provided with external threads, and the inner wall of inspection cover 182 is provided with internal threads that match the external threads. This facilitates the installation of inspection cover 182 on inspection port 170, thereby ensuring the noise reduction effect of elbow 110. The provision of block 181 further seals inspection port 170, enhancing the noise reduction effect. The provision of retaining groove 171 and retaining boss 1811 facilitates the placement of block 181 on inspection port 170. The outer end of block 181 is also provided with a gripping portion for removal, which can be two raised strips or a handle.

[0029] In some embodiments of the present application, Figure 3As shown, annular grooves are provided on the inner walls of the water inlet joint 120 and the drain joint 130 . A first sealing ring 191 is embedded in the annular groove of the water inlet joint 120 , and a second sealing ring 192 is embedded in the annular groove of the drain joint 130 .

[0030] In the embodiment of the present application, since sealing rings are provided at the water inlet joint 120 and the drain joint 130, the water inlet joint 120 and the drain joint 130 are connected to the corresponding drain pipe in a flexible socket connection. On the one hand, the sealing is better to avoid water leakage. On the other hand, the flexible socket connection also allows axial expansion and contraction between the water inlet joint 120, the drain joint 130 and the drain pipe, thereby avoiding bending and damage of the drain pipe, the water inlet joint 120 and the drain joint 130 due to thermal expansion and contraction.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0032] Obviously, those skilled in the art may make various changes and modifications to this application without departing from the spirit and scope of the inventive concept. Thus, if such changes and modifications fall within the scope of the claims of this application and their equivalents, this application is intended to include such changes and modifications.
