Description

Technical Field

[0001] This utility model specifically relates to a stable connection of water supply and drainage pipelines in municipal engineering, belonging to the field of water supply and drainage pipeline connection technology. Background Technology

[0002] In municipal engineering, water supply and drainage systems are a key component of urban infrastructure. With the rapid development of cities, the demand for water supply and drainage pipelines is increasing. Municipal engineering water supply and drainage pipelines are mainly used for the collection and discharge of urban sewage and rainwater. They are generally laid under municipal roads. The ever-expanding scope of pipeline laying and the complex and diverse environments have a significant impact on the stable connection of water supply and drainage pipelines. Unstable connections of water supply and drainage pipelines can lead to water leakage, which not only wastes water resources and pollutes the environment, but may also cause safety hazards such as ground subsidence. Stable connections of water supply and drainage pipelines can effectively ensure the stability of the pipelines, thereby meeting the modern urban demand for high quality, long life and low maintenance in municipal engineering.

[0003] For example, CN219888943U discloses a stable connection structure for municipal engineering water supply and drainage pipelines, including a first fixing ring. The inner wall of the first fixing ring has a first groove, and a first sealing strip is snapped into the inner wall of the first fixing ring. Two first fixing plates are fixedly connected to the outer surface of the first fixing ring. A second fixing ring is provided on the bottom surface of the first fixing plate, and a second groove is provided on the inner wall of the second fixing ring. Through the cooperation of the first fixing ring, the first groove, the first sealing strip, the second fixing ring, the second groove, and the second sealing strip, not only can the sealing effect of the equipment be improved, but it is also convenient for workers to replace the first and second sealing strips. This allows the equipment to fix and seal pipes of different sizes, thereby greatly increasing the practicality of the equipment. The cooperation of the nut, shank, screw, spring, and plug prevents the nut from falling off.

[0004] However, the existing connection structures of some water supply and drainage pipes are mostly simple connections of bolts and nuts. In a relatively dry environment, the connection of water supply and drainage pipes is relatively stable, but in a relatively humid environment, the bolts and nuts at the pipe connection are prone to corrosion, which leads to unstable water supply and drainage pipe connections and leakage, thus affecting the quality of water supply and drainage pipes in municipal engineering. Utility Model Content

[0005] The purpose of this utility model is to provide a stable connection for municipal engineering water supply and drainage pipelines in order to solve the above-mentioned problems, thereby solving the problem of water leakage caused by unstable connection of municipal engineering water supply and drainage pipelines.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a stable connection of municipal engineering water supply and drainage pipelines, including a first pipeline and a second pipeline. A first connector is fixedly installed at one end of the first pipeline, and a second connector is fixedly installed at one end of the second pipeline.

In use, the first connector is sleeved on the second connector to enhance the sealing effect and facilitate use.

[0009] Preferably, each of the connecting holes is provided with a bolt for connecting the first connector and the second connector. Each bolt passes through the connecting hole, and one end of each bolt is threaded with a nut. Each bolt is fitted with a washer, which is located on one side of the nut. In use, the first connector and the second connector are connected by the cooperation of the bolt and the nut. The washer is used to enhance the connection effect between the bolt and the nut.

[0010] Preferably, one side of the washer abuts against one end face of the first connector, and the other side of the washer abuts against one side of the nut. In use, the washer provides a larger contact area, thereby achieving a better connection between the bolt and the nut.

[0011] Preferably, the sealing cover includes a cover body, one end face of which is provided with a third sealing ring, and the other end face of which is fixedly mounted with a connecting seat. A through hole is fixedly opened on the surface of the connecting seat, and a pull ring is fixedly mounted on the connecting seat, and the pull ring passes through the through hole. In use, the cover body is moved by pulling the pull ring, thereby achieving the effect of quick-release installation of the sealing cover, which is convenient to use.

[0012] Preferably, the other end face of the first connector and the second connector are respectively provided with a third sealing groove, and the third sealing groove corresponds to the position of the connecting hole. In use, the third sealing groove is used in conjunction with the third sealing ring to achieve sealing of the head of the bolt and the nut.

[0013] Preferably, the sealing covers are all installed on the connection holes of the first connector and the second connector. When in use, the third sealing groove corresponds to the connection hole, which facilitates the installation and removal of the sealing covers and makes them easy to use.

[0014] The beneficial effects of this utility model are as follows: During use, the positioning holes and positioning posts can assist in the positioning and connection of the first and second connecting parts, thereby reducing the working time of the workers. The first and second connecting parts are respectively provided with sealing grooves and sealing rings for sealing. By fitting the first connecting part onto the second connecting part, a better sealing effect can be achieved. The other end face of both the first and second connecting parts is provided with a sealing cover. After the first and second connecting parts are connected with bolts and nuts, by installing the sealing cover on the connection port, the bolt head and nut can be sealed, thereby reducing the corrosion of the water supply and drainage pipe connection and thus reducing water leakage at the water supply and drainage pipe connection, thereby increasing the service life of the connection structure and reducing costs.
