Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a corrosion-resistant pipeline connection component for sewage treatment. Background Technology

[0002] Corrosion-resistant pipe connection assemblies for wastewater treatment are used to connect different corrosion-resistant pipes together, ensuring the sealing and stability of the piping system to adapt to the complex chemical environment during wastewater treatment.

[0003] Existing patents, such as Chinese Patent Publication No. CN220268733U, relate to the field of pipe connection technology and disclose a pipe connection assembly. This assembly includes two pipes, each with a flange welded to its end. Both flanges have mounting holes into which bolts are inserted. A sealing ring is placed between the outer seams of the two flanges. An annular groove is formed on the flange outside the mounting hole, with a cap threaded into the groove. A second sealing ring is placed at the bottom of the groove. This structure, using the cap and sealing ring, seals both ends of the flange connection bolts, protecting them. Simultaneously, the sealing ring prevents external moisture from entering through the flange connection seam and corroding the bolts. The entire structure effectively protects the flange connection bolts, extends their service life, and minimizes the risk of leakage due to bolt corrosion causing flange loosening.

[0004] Although the aforementioned patented technology can prevent external moisture from entering the flange connection seam and corroding the bolts, and the entire structure can effectively protect the bolts of the flange connection, improve the service life of the bolts, and minimize the risk of leakage caused by loosening of the flange connection due to bolt corrosion, the above-mentioned connection components are usually not suitable for connecting two pipes of different diameters. It is often difficult to guarantee the sealing effect during connection. Therefore, a corrosion-resistant pipe connection component for sewage treatment is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the above-mentioned patented technology that the connecting components are usually not adaptable to connecting two pipes of different diameters, and it is usually difficult to guarantee the sealing effect during connection. Therefore, a corrosion-resistant pipe connecting component for sewage treatment is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a corrosion-resistant pipe connection assembly for sewage treatment, comprising a connecting pipe, wherein four first annular grooves are formed on the inner wall of the connecting pipe near both ends, and a sealing groove is formed on one side of the inner wall of each of the first annular grooves. A sealing gasket is embedded and fixedly connected inside each of the sealing grooves.

A connecting rod is slidably connected through the inside of each protrusion. Both ends of the connecting rod pass through the protrusions and are slidably connected to them. A nut is fitted and threadedly connected to one end of each connecting rod. A groove is opened on one side wall of each protrusion. An insert is embedded in the inside of each groove. The insert is fixedly connected to one end of each connecting rod.

[0007] Preferably, the diameters of the four first annular grooves decrease sequentially from the outside to the inside.

[0008] Preferably, the outer surface of the sealing gasket is inclined inward, and one end of the sewage inlet pipe and the sewage outlet pipe are adapted to the sealing gasket.

[0009] Preferably, a corrosion-resistant layer is embedded and fixedly connected to the inner wall of the connecting pipe near the center.

[0010] Preferably, the inner wall of the rotating cover is threaded, and both ends of the connecting pipe are embedded inside the rotating cover and adapted to the threads on its inner wall.

[0011] Preferably, each side wall of the rotating cover is provided with a second annular groove, and a rotating annular plate is embedded and rotatably connected inside the second annular groove, and the rotating annular plate is fixedly connected to the ring.

[0012] Preferably, one of the rotating covers has a third annular groove on one side wall, a connecting ring is embedded inside the third annular groove, the third annular groove is in communication with the insert groove, and the connecting ring is fixedly connected to the insert block.

[0013] Preferably, the surface of the rotating cover is provided with anti-slip texture.

[0014] Preferably, one side wall of the fixed retaining ring is embedded inside the inner wall of the rotating cover and slidably connected thereto.

[0015] Preferably, the edges of the bump and the convex plate are rounded.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, by embedding one end of two pipe fittings of different diameters into the first annular grooves at both ends of the connecting pipe, the two different pipe fittings can be connected, thereby improving the practicality of the connecting component.

[0018] 2. In this utility model, by placing two rotating sleeves on both ends of the connecting pipe and rotating them, the rotating sleeves can be threaded onto both ends of the connecting pipe. This allows the rotating sleeves to press against the fixed retaining ring, which in turn causes one end of the drain pipe and the inlet pipe to press against the sealing gasket. This can improve the sealing performance of the connecting components and prevent leakage due to poor sealing. Attached Figure Description

[0031] Working principle: By embedding one end of the inlet pipe 5 and outlet pipe 6 of different diameters into the first annular groove 2 at both ends of the connecting pipe 1, the rotating cover 8 is then rotated and fitted onto both ends of the connecting pipe 1. During the rotation, the rotating cover 8 moves radially along the thread and pushes the fixed retaining ring 7. The fixed retaining ring 7 then causes the inlet pipe 5 and outlet pipe 6 to squeeze the sealing gasket 4. Then, by rotating the ring 12, the protrusion 13 is aligned with the protrusion plate 19. The connecting rod 20 can then pass through the protrusion 13 and the protrusion plate 19. At this time, the connecting ring 15 and the insert 17 will be embedded into the third annular groove 14 and the insert groove 16, respectively. Finally, by fitting the nut 21 and threading it onto the other end of the connecting rod 20, the rotating cover 8 can be prevented from automatically detaching during use.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
