[0023] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model.

For example, detachable connection can select screw connection, bolt connection, threaded connection, snap connection, mortise and tenon connection, magic tape connection and other methods as needed. The various technical features in the creation of the present utility model can be interactively combined without conflicting with each other.

[0024] Referring to Figure 1 , Figure 2 , an HDPE spiral silent drain pipe device includes a drain pipe 1 and a socket joint 2. Among them, a spiral protrusion 3 is provided inside the drain pipe 1. The spiral protrusion design on the inner wall of the pipe makes the water flow generate eddy currents when passing through, thereby slowing down the impact speed of the water flow and reducing the impact noise of the water flow on the pipe wall; the end of the drain pipe 1 is inserted into the socket joint 2, which simplifies the installation process, improves the construction efficiency and reduces the installation cost; a sealing member 4 is provided at the connection between the drain pipe 1 and the socket joint 2 to ensure the sealing and stability of the pipe connection.

[0025] Referring to Figure 2 , in the embodiment of the present utility model, the spiral angle of the spiral protrusion 3 is set to 10° - 30°, the pitch of the spiral protrusion 3 is set to 500 mm - 700 mm, and the height of the spiral protrusion 3 is set to 8 mm. By accurately calculating the spiral angle, height and pitch of the protrusion, not only the noise reduction effect of the pipe is improved, the impact noise of the water flow is effectively reduced, but also the rigidity and toughness of the pipe are enhanced, and the service life is extended.

[0026] Specifically, the pipe wall of the drain pipe 2 includes a high-density polyethylene layer, a barium sulfate layer and a high-density polyethylene layer from outside to inside, that is, the drain pipe 2 is made of a three-layer composite material. The barium sulfate intermediate layer in the three-layer composite material has good sound insulation effect, further enhancing the noise reduction ability, effectively reducing the impact noise generated when the water flow passes through, and meeting the requirement that the night noise does not exceed 30 DB.

[0027] Specifically, the end of the drain pipe 1 is provided with a chamfer, and the angle of the chamfer is set to 15° - 30°, so that the thickness of the bevel of the drain pipe 1 is about 1 / 2 - 1 / 3 of the wall thickness of the pipe material, which plays a certain guiding role and facilitates the insertion of the drain pipe into the interface.

[0028] Specifically, the cross-section of the spiral protrusion 3 is set as an isosceles triangle structure, and the base of the isosceles triangle is connected to the inner wall of the drain pipe 1 to improve the wall attachment effect of the water flow.

[0029] Refer to Figure 3 , in the embodiment of the present invention, an installation groove 21 is provided inside the socket joint 2, and the seal 4 is arranged in the installation groove 21, which can not only ensure the unobstructed insertion of the drain pipe 1 into the socket joint 2, but also ensure the sealing performance of the pipeline connection; the seal 4 is set as a rubber ring, which forms a tight sealing structure between the socket end and the spigot end of the pipeline, significantly improving the sealing performance and stability of the pipeline connection and reducing the risk of leakage.

[0030] The drain pipe device of the present invention can be installed and connected by two socket and spigot installation methods. The specific installation methods are as follows:

[0031] Embodiment 1:

[0032] The drain pipe device of the present invention adopts a flexible socket and spigot installation method. The specific installation steps are as follows: Select the diameter of the drain pipe 1 according to the drainage construction drawing. The end face of the cut pipe material should be perpendicular to the pipe axis. At the same time, remove the burrs and rough edges on the cut end face of the pipe material. Then use a special chamfering machine to chamfer the pipe end by 15° - 30°, and the thickness of the bevel is about 1 / 2 - 1 / 3 of the wall thickness of the pipe material. Clean the inner side of the socket and the outer side of the spigot with cotton yarn or dry cloth. If necessary, use a cleaner such as acetone to keep it clean. Then subtract 10 mm from the socket depth of the pipe fitting, which is the insertion length of the pipe material. Mark this length on the pipe material. Finally, check and adjust the rubber sealing ring, and evenly apply the lubricant on the surface of the rubber sealing ring and the outer surface of the socket of the pipe material or pipe fitting. Insert the socket of the pipe material or pipe fitting into the socket of the pipe fitting at a uniform speed until the marked line is reached, and the pipeline connection can be completed.

[0033] Embodiment 2:

[0034] The drain pipe device of the utility model adopts the hot melt socket connection installation method, and the specific installation steps are as follows: Cut the drain pipe 1 according to the required length. The end face of the cut drain pipe 1 should be perpendicular to the pipe axis. At the same time, remove the burrs and rough edges on the cut end face of the drain pipe 1, and ensure that the connection end face between the drain pipe 1 and the socket interface 2 is clean, dry, and oil-free. When necessary, it can be cleaned with a dry cloth or acetone, etc. Then, use a caliper and a suitable pen to measure and mark the socket depth at the insertion end of the drain pipe 1. Insert the insertion end of the drain pipe 1 into the heating sleeve of the hot melt machine without rotation until the marked depth is reached. At the same time, push the socket interface 2 onto the heating head of the hot melt machine without rotation until the specified mark is reached. After the heating time is reached, immediately remove the drain pipe 1 and the socket interface 2 from the hot melt machine at the same time, and then quickly and linearly insert them into place without rotation to complete the pipe connection.
