Rubber joint for sewage treatment pipeline

The utility model discloses a rubber joint for a sewage treatment pipe, including a rubber tube body and a flange plate connected to the pipe to be connected to each end of the rubber pipe body. The outer side of the rubber pipe body is arranged in a circumferential direction with a positioning ring groove for locating and preventing the flange to be positioned and taken off. There is also a circular convex set used to fit in with the circumference of the flange in the flange, and the inner side of the flange is fitted with the circular convex in the circumference direction. When the flange is installed, the flange plate is inserted in the positioning ring groove along the circumference and is installed in the positioning ring trough through the fastening force, and the ring groove is positioned as a whole shaft of the flange plate. When the flange is connected to the flange structure of the pipe to be connected, it is not easy to form a loosening, thus ensuring a stable connection structure of the pipe as a whole, when the flange is connected to the flange structure to be connected to the pipe.

Rubber joint for sewage treatment pipeline

technical field

The utility model relates to the field of sewage treatment, in particular to a rubber joint for sewage treatment pipelines.

Background technology

In the process of pipeline installation of sewage treatment, in order to absorb the vibration, eccentricity, distortion and stretching produced by the pipe supercharging equipment, it usually needs to be used to the flexural rubber joint, connecting the pipes at both ends of the rubber joint to realize the connection of the whole pipe. In the field of sewage treatment, the existing rubber joints are easily connected by the external force when connecting the pipe to the flange of the rubber joint, and the above problems will have a significant impact on the normal conduct of the sewage treatment process, and even need to stop the maintenance and waste of the operation. Force physical force.

Therefore, it is necessary to improve the existing rubber joints of sewage treatment pipelines, making it difficult to cause joint loosening when connecting with the pipes to be connected.

Practical new content

In view of this, the utility model provides a rubber joint for sewage treatment pipeline, which is simple in structure and easy to use. It is not easy to cause joint loosening when connecting the flange to the pipe to be connected.

The rubber joint of the utility model is used for the rubber pipe body and the corresponding rubber pipe body at each end. The flange of the rubber pipe body is arranged in the circumference direction, which is used for the flange plate to locate and install and prevent from being removed, and the positioning ring grooves are also arranged in the slot. The utility model is used for the annular protrusion which is embedded in the periphery of the flange pan, and the inner side of the flange plate is arranged with a groove embedded with the annular protrusion along the circumferential direction.

Further, the two ends of the rubber tube body are not provided with the first radial flange and the second radial flange, and the positioning ring groove is formed by the axial gap between the first radial flange and the second radial flange.

Further, the first radial flange extends outwards along the radial direction of the rubber pipe body, and the clamping part is formed when the flange plate is connected with the flange structure to be connected to the pipeline.

Further, the reinforcing ring is arranged at the location of the root of the first radial flange and the second radial flange.

Further, the ends of the rubber tube body are respectively formed with a positioning and stopping structure for extending into the pipeline to be positioned and matched.

The beneficial effect of the utility model is that the rubber joint used in the sewage treatment pipe of the utility model is set by setting the positioning ring groove and setting the positioning convex in the positioning ring groove. When the flange plate is installed, the flange plate is inserted in the positioning ring groove along the circumference and is installed in the fixed ring groove through the fastening force, and the ring groove is positioned to the flange. The body shape is axially restricted, and the positioning convex is embedded in the socket to form a stable anti - off structure. When the flange structure is connected to the flange structure to be connected to the pipe, it is not easy to form the loosening, thus ensuring the pipe to form a stable connection structure.
