Description

Technical Field

[0001] The utility model relates to the field of drainage pipes, in particular to a high-strength explosion-proof drainage pipe. Background Art

[0002] High-strength composite drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including trunk pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the streets or anywhere else, as long as they are used for drainage, they should be counted as drainage pipes;

[0003] The utility model patent with publication number CN 212506618 U in the prior art proposes a high-strength composite drainage pipe. During the normal use of the drainage pipe, when water flows through the inner wall of the drainage pipe, when noise passes through the sound insulation layer, it is repeatedly reflected inside the sound insulation groove until it is weakened and absorbed by the sound insulation layer, which has a good sound insulation effect and is convenient for stabilizing the placement of the pipe body. The drainage pipe has a simple structure and a better use effect than the traditional method.

[0004] However, it disperses the impact of water flow through the cooperation of water baffles and water guide holes. Although it can alleviate the impact force, the water guide holes are easily blocked due to stains and dust. It is not easy to clean it inside the pipe, which can easily cause pipe blockage and is not conducive to being set in the drainage pipe. At the same time, it does not have the ability to strengthen the seal of the pipe joints, and the external connection position of the pipe is prone to leakage when it is pressurized. Therefore, we need to upgrade and transform it based on the existing technology to overcome its existing problems and shortcomings. Utility Model Content

[0005] The purpose of the utility model is to provide a high-strength explosion-proof drainage pipe to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0023] The guide ring 51 facilitates the water flow at the upper end to be guided to the central position, the rotating shaft 53 and the hinge seat 52 cooperate to facilitate the rotation of the movable plate 54, and the stainless steel spring 55 facilitates the elastic reset of the movable plate 54.

[0024] Preferably, the connecting assembly 4 comprises a lower flange 41 and an upper flange 42, a flange bolt 43 is connected between the lower flange 41 and the upper flange 42, an inner tube body 44 is provided inside the lower flange 41 and the upper flange 42, a conical head 45 is provided at the upper and lower ends of the inner tube body 44, the lower flange 41 is fixed on the main tube body 2, the upper flange 42 is fixed on the external tube 3, the two ends of the inner tube body 44 are respectively fitted and inserted in the main tube body 2 and the external tube 3, a sealing gasket 46 is fixed at the middle position of the outer wall of the inner tube body 44, an embedded groove 47 is opened on the inner side of the lower flange 41 and the upper flange 42, and the sealing gasket 46 is squeezed and fitted in the embedded groove 47;

[0025] The cooperation of the lower flange 41, the upper flange 42 and the flange bolt 43 facilitates the fixed connection between the main pipe body 2 and the external pipe 3. The internal pipe body 44 and the conical head 45 facilitate the internal conduction of the main pipe body 2 and the external pipe 3, thereby reducing the pressure at the connection and avoiding leakage problems at the connection. The sealing gasket 46 further improves the sealing of the connection.

[0026] The use principle and use process of the utility model: when using, firstly, a group of inner tube bodies 44 can be inserted into the upper end of the main tube body 2, so that the outer sealing gasket 46 of the inner tube body 44 is clamped in the inner embedding groove 47, and then the main tube body 2 is docked with the external tube 3, so that the upper end of the inner tube body 44 is inserted into the external tube 3, so that the lower flange 41 and the upper flange 42 are correspondingly fitted, and the two groups of flanges are fixedly connected by the flange bolt 43. The inner tube body 44 and the sealing gasket 46 can effectively improve the sealing of the pipeline connection and reduce the pressure on it, avoiding the connection. The leakage problem occurs. During the use of the main pipe 2, the discharged waste water will be discharged downward through the guide ring 51, and the waste water passing through the guide ring 51 will first contact the movable plate 54. The movable plate 54 blocks the water flow and loses its impact force. After passing through the movable plate 54, the water flow falls into the corner position of the main pipe 2, effectively preventing the main pipe 2 from being impacted and causing the pipeline to rupture. At the same time, the movable plate 54 can be compressed outwardly under the action of the stainless steel spring 55, so that the middle opening position expands, effectively preventing the pipeline from being blocked or having poor circulation.
