DETAILED DESCRIPTION

[0026] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", "clockwise", "counterclockwise", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0027] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] In order to solve the technical problem of poor sound insulation effect of existing silent pipe embedded parts, this example discloses a FRPP silent pipe embedded part, which is made of FRPP material, so that it has high structural strength to withstand the extrusion force during concrete pouring and ensure service life. Figure 1 In this embodiment, the FRPP silent pipe includes an upper joint 1 and a lower joint 2, wherein the upper joint 1 and the lower joint 2 are coaxially connected and respectively connected to the silent pipes on both sides to construct a corresponding water supply and drainage pipe system.

[0029] In this embodiment, the upper joint 1 and the lower joint 2 are an integrated structure, which is formed by injection molding in one step. Figure 1 and Figure 2 The inner diameter of the upper joint 1 matches the outer diameter of the silent pipe to be inserted, so that the silent pipe can be firmly inserted into the upper joint 1 during installation, and the upper joint 1 pre-buried in the building structure supports and limits the silent pipe to prevent it from shaking. In order to avoid the silent pipe from being over-inserted and affecting the insertion depth of the lower silent pipe, or to avoid the silent pipe from being inserted too short and causing leakage or instability of the pipe body, in this embodiment, see Figure 2 The upper joint 1 includes a reducing shoulder 11 provided at the bottom position of the upper joint. The minimum diameter of the reducing shoulder 11 is smaller than the outer diameter of the silent pipe. The insertion depth of the silent pipe is limited by the reducing shoulder 11 to ensure the installation effect of the silent pipe. At the same time, the water transported by the silent pipe connected to the upper joint 1 directly enters the lower joint 2. Part of the water flowing to the reducing shoulder 11 can also flow into the lower joint 2 under the diversion effect of the inclined slope of the reducing shoulder 11, which can reduce the risk of leakage and water retention and improve the drainage effect.

[0030] See also Figure 2 The lower joint 2 includes a socket cavity 21 provided at the top of the lower joint. The thickness of the socket cavity 21 matches the thickness of the silent pipe, and the inner edge contour of the cavity matches the inner edge and outer edge contour of the silent pipe to be inserted, respectively, so that the silent pipe can be inserted into the socket cavity 21. The cavity wall of the socket cavity 21 limits the silent pipe and prevents the inserted silent pipe from shaking. In addition, in this embodiment, the socket cavity 21 has a certain depth, and at the same time controls the end of the silent pipe inserted into the socket cavity 21 to leave a certain gap with the bottom of the cavity, thereby achieving the purpose of bearing the thermal expansion and contraction of the silent pipe, reducing or eliminating the adverse effects of the silent pipe on the water supply and drainage pipeline caused by the change in the expansion and contraction length due to the influence of the ambient temperature.

[0031] In addition, in order to reduce the noise generated by the embedded parts of the silent pipe, in this embodiment, Figure 2The embedded part also includes a spiral guide flange 3 provided on the inner wall of the embedded part. In this example, the spiral guide flange 3 is provided on the outer edge surface of the inner groove wall of the socket cavity 21, so that the water discharged from the silent pipe socketed at the upper joint 1 is guided by the spiral guide flange 3, causing the water to generate a vortex, thereby reducing the potential energy of the water body and reducing the water hammer effect generated by the water body, thereby achieving the purpose of reducing drainage noise. Among them, in this embodiment, considering that in some cases the water body flows down along the pipe wall, in order to ensure that the water body flowing down at any point along the pipe wall can generate a vortex effect after contacting the spiral guide flange 3, thereby reducing the potential energy of the water body, the number of spiral turns of the spiral guide flange 3 is set to be no less than 1.5 turns, so that the water body flowing down along the wall of the silent pipe has at least 0.5 turns of the spiral guide flange, which can play a diversion role on the corresponding part of the water body, thereby ensuring the silent effect of the silent pipe embedded part.

[0032] In this embodiment, the upper silent pipe is limited in the upper joint 1 by the reduced diameter shoulder 11, and the lower silent pipe is correspondingly inserted into the socket cavity 21, so that the water flowing down from the upper silent pipe is guided by the spiral guide flange 3 after passing through the corresponding position of the reduced diameter shoulder 11 and then flows into the lower silent pipe, and the lower silent pipe is socketed into the socket cavity 21, so that the water flow path is relatively smooth under the action of gravity, and the water is not easy to leak upward from the connection between the upper interface and the silent pipe and the lower interface and the silent pipe, which can play a greater role in preventing water seepage. In order to avoid the problem of blocked drainage due to pipe blockage, water accumulation in the silent pipe and then leakage from the connection between the embedded parts and the silent pipe, in this embodiment, see Figure 1 and Figure 2 , sealing rings 4 are respectively provided at both ends of the embedded parts. Specifically, in this example, sealing shoulders 12 for filling the sealing rings 4 are respectively provided at the ends of the upper joint 1 and the lower joint 2. The depth of the sealing shoulder 12 is not less than the thickness of the sealing ring 4, and the diameter of the sealing shoulder 12 is not less than the diameter of the sealing ring 4. As a result, after the sealing ring 4 is filled into the sealing shoulder 12, the inner edge of the sealing ring 4 contacts the outer edge of the silent tube, thereby achieving a sealing and anti-seepage effect. Then, in order to prevent the sealing ring 4 from detaching and causing the seal to fail, in this embodiment, see Figure 1 and Figure 2A sealing pressure ring 41 is embedded in the sealing shoulder 12. The cross section of the sealing pressure ring 41 is correspondingly angled, and the outer edge diameter thereof matches the diameter of the sealing shoulder 12. This allows the sealing pressure ring 41 to be clamped on the sealing shoulder 12 and to press the sealing ring 4. In addition, in order to improve the positioning effect of the sealing pressure ring 41, in this example, a positioning flange is provided on the outer edge surface of the sealing pressure ring 41, and a sealing groove is provided on the corresponding surface of the sealing shoulder 12. Therefore, after the sealing pressure ring 41 is pressed into the sealing shoulder 12, the sealing flange has a certain slight deformation characteristic, which allows the positioning flange to slide into the sealing groove on the wall of the sealing shoulder, thereby ensuring the compression effect of the sealing pressure ring 41.

[0033] In addition, in this embodiment, in order to ensure the sealing effect of the sealing ring 4, the annular surface of the sealing ring 4 used to contact the silent tube is provided with a plurality of sealing lips, thereby achieving multiple sealing protection effects, and each sealing lip includes an inclined surface corresponding to the insertion direction of the silent tube. On the one hand, the inclined surface can guide the insertion of the silent tube and reduce the insertion resistance of the silent tube; on the other hand, since the inclined surface is deflected toward the insertion direction of the silent tube, the leakage resistance of the water body in the reverse direction of the insertion direction of the silent tube is increased, so as to achieve the purpose of improving the sealing effect.

[0034] See also Figure 3 and Figure 4 In other embodiments, considering the differences in structural thickness of different buildings, the adaptability of the embedded silent pipe parts to the embedded thickness of the building structure is achieved, providing a universal effect of the embedded parts. In this example, the upper joint 1 and the lower joint 2 are connected by a coaxial thread. By adjusting the length of the threaded connection accordingly, the height of the embedded part can be adjusted, thereby achieving the purpose of adapting to different embedded thicknesses. For details, see Figure 4 In this example, the bottom end of the upper joint 1 is provided with an externally threaded connection portion 13. Correspondingly, the outer edge of the groove wall of the socket cavity of the lower joint 2 in the embedded part is also a threaded structure, thereby realizing a threaded connection between the upper joint 1 and the lower joint 2, and further achieving adaptive adjustment of the embedded part height. In addition, in this example, a spiral guide flange 3 is provided at the inner edge of the externally threaded connection portion to achieve a diversion effect. After the water passes through the diversion effect of the spiral guide flange 3, it directly enters the lower silent pipe, so that the water is not likely to flow back along the threaded connection and leak, which has a good anti-leakage effect.

[0035] To prevent relative movement between the threaded upper joint 1 and the lower joint 2, which would cause the height of the embedded part to change during pre-embedded casting, in this embodiment, a fastening ring 14 is threadedly connected to the external threaded connection portion 13 of the upper joint 1. After adjusting the embedded part height to an appropriate level, the fastening ring 14 is screwed in so that it contacts the end surface of the lower joint, thereby achieving a fastening effect and preventing relative rotation between the upper joint 1 and the lower joint 2. In addition, to avoid the risk of water accumulation in the embedded part due to clogging of the lower silent pipe and leakage from the threaded connection, in this embodiment, a corresponding sealing groove is provided on the annular surface of the fastening ring 14 for contacting the external threaded connection portion 13, and a sealing ring 15 is correspondingly embedded in the sealing groove. Specifically, the sealing groove is provided at the inner edge of the end surface of the fastening ring for contacting the lower joint, that is, the sealing ring 15 is limited by the fastening ring 14 to the intersection of the external threaded connection portion and the lower joint, thereby achieving a sealing effect and preventing leakage.
