[0015] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0016] Referring to Figs. 1-3 A drainage pipe joint with a thread connection and a water down end face inner socket adhesive, comprising at least two groups of liquid inlet ports 1 and a group of liquid outlet ports 4, the outer side of the liquid inlet port 1 is provided with a thread 2, the liquid outlet port 4 comprises a double-layer structure of a first pipe body 5 and a second pipe body 6, the second pipe body 6 is arranged on the inner side of the first pipe body 5, and an inner groove 7 is formed between the first pipe body 5 and the second pipe body 6.
[0017] As Fig. 2 And Fig. 3 It is a connection mode of some connecting pipe ports in the prior art, Fig. 2 The external connecting pipe port is arranged in the inner part of the connecting pipe port, when liquid flow passes, the end of the external connecting pipe port is directly impacted by the liquid flow, so that more vibration and noise are generated at the connecting pipe port and the external connecting pipe port, and the connecting position of the connecting pipe port and the external connecting pipe port is prone to loosening and water leakage in long-term use; Fig. 3The connecting pipe opening and the external connecting pipe opening are flatly connected, and the connecting position of the connecting pipe opening and the external connecting pipe opening cannot be completely tightly attached, even if the two are tightly attached, the pipe deformation will affect the attachment effect in the use process, and the liquid flow will still generate impact vibration at the connecting position after being converged, noise is generated, and the subsequent connection sealing performance is affected;
[0018] The liquid outlet port 4 is provided with a double-layer structure of the first pipe body 5 and the second pipe body 6, wherein the second pipe body 6 is an inner pipe, the second pipe body 6 is an extension of the internal flow passage of the connecting pipe opening, the first pipe body 5 is an outer pipe, and the first pipe body 5 is integrally arranged outside the second pipe body 6, and an inner groove 7 is formed between the two. When the present technical solution is connected with the external connecting pipe opening, the external connecting pipe is clamped into the inner groove 7, the end of the external connecting pipe is hidden in the inner groove 7, and the external connecting pipe and the connecting pipe opening are fixedly connected by glue and kept sealed. The connecting position of the external connecting pipe and the connecting pipe opening will not be in contact with the liquid flow, thereby avoiding the impact of the liquid flow. The liquid flow is discharged through the liquid inlet port 1 and the second pipe body 6, and the liquid flow is transported more smoothly, which helps to reduce the vibration in the liquid flow process. The noise of the connected pipe is small, and the use stability is good.
[0019] The liquid inlet port 1 is fixed by screw thread connection, the pipe opening is convenient to connect, and the use effect is good.
[0020] Further, the length of the second pipe body 6 is less than the length of the first pipe body 5, and the wall thickness of the second pipe body 6 gradually decreases from the rear end to the front end.
[0021] Through the technical solution, the wall thickness of the second pipe body 6 gradually decreases from the rear to the front, so that the distance between the second pipe body 6 and the wall of the external connecting pipe opening becomes smaller and smaller, thereby guiding the liquid flow more smoothly. The liquid flow passes through the second pipe and then passes through the first pipe to be transported backward, and will not directly collide with the connecting position, thereby reducing the vibration generated in the liquid transportation process; the first pipe body 5 is slightly longer than the second pipe body 6, which can effectively support the external connecting pipe opening, increase the friction force, and make the connection effect of the connecting pipe opening and the external connecting pipe opening better.
[0022] Further, the inner groove 7 is steppedly reduced from the opening to the inside.
[0023] Through the technical solution, the inner groove 7 is largest at the opening and smallest at the end, and is steppedly reduced in the middle. Correspondingly, the external connecting pipe opening which is connected with the inner groove 7 is provided with a stepped structure, which is convenient to clamp and can effectively increase the friction force to avoid leakage in connection.
[0024] Further, the liquid inlet port 1 is provided with two groups, and the two groups of liquid inlet ports 1 are connected with external pipe fittings through threads 2 and thread sleeves.
[0025] Further, the arc-shaped flow guide part 3 is arranged on one group of liquid inlet ports 1.
[0026] The flow guide part 3 can make the confluence of the two groups of liquid inlet ports 1 more stable, reduce the impact, and effectively reduce the vibration and noise.
[0027] Working principle: the liquid outlet port 4 connected with the pipe opening is provided with a double-layer structure of a first pipe body 5 and a second pipe body 6, the second pipe body 6 is an inner pipe, the second pipe body 6 is an extension of the inner flow channel of the pipe opening, the first pipe body 5 is an outer pipe, and the first pipe body 5 is integrally arranged outside the second pipe body 6, and an inner groove 7 is formed between the two pipes, when the technical scheme is connected with the external pipe opening, the external pipe is clamped into the inner groove 7, and the end of the external pipe is hidden in the inner groove 7, so that the impact of the liquid flow is avoided, the vibration in the liquid flow process is reduced, the noise of the connected pipe is small, and the use stability is good.
