Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a flange for a water pump. Background Art

[0002] A water pump flange, also known as a flange or flange, is a disc-shaped component primarily used to connect water pumps to pipes or other equipment. It is typically made of metal materials such as steel, copper, and aluminum, and possesses sufficient strength and rigidity to withstand the pressure and tension in the system. A flange consists of a circular disk with one or more holes in the center for mounting bolts or nuts to achieve a tight connection with other flanges.

[0003] When connecting flanges, the two disks are usually first made to fit together and the holes are aligned, and then the two are fixedly connected with bolts to achieve flange connection. However, the above connection method has high requirements on the strength and precision of the bolts, because the bolts bear almost all the loads at the connection. While being pulled, they are also subjected to the shear force caused by the relative rotation between the disks, which makes the working conditions of the bolts more complicated and severe. Long-term use can easily lead to a decrease in the connection effect of the bolts, resulting in poor airtightness of the connection and affecting normal use. In addition, due to the lack of positioning and guiding measures, it takes a lot of time to align the holes when the flanges are docked, and the holes will be misaligned from time to time during the connection process and need to be corrected. Therefore, a flange for a water pump is proposed to address the above problems. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a flange for a water pump, which can, after the flange is connected, fit tightly between the bite block and the bite groove, so that the disc body cannot rotate relative to each other, and the torque transmitted by the pipeline will be shared by the clamping action between the bite blocks, and the bolt connector that plays a connecting role only needs to share the axial tension, which can greatly optimize the stress condition of the bolt connector, so that the strength and precision requirements of the bolt connector are not too high, and the effective connection can be maintained for a long time. When connecting the disc body, the engagement between the bite block and the bite groove can play a guiding and positioning role, so that workers do not need to spend effort to align the holes. At the same time, in the process of connecting with the bolt connector, the disc bodies cannot be offset, and it can be ensured that the holes are always aligned, which is convenient for installation and connection. It solves the technical problems in the prior art that the bolt working conditions for connecting flanges are relatively complex and severe, long-term use can easily lead to a reduction in its connection effect, and it takes a lot of time to align the holes when the flanges are connected, and the holes will be misaligned from time to time during the connection process and need to be corrected.

At the same time, in the process of connection using the bolt connector, the disk bodies cannot be offset, which can ensure that the holes are always aligned, making it easy to install and connect.

[0008] In a possible implementation, the end surface of the disc body provided with the engaging block is provided with a centrally arranged annular groove, and a sealing ring is fixedly provided in the annular groove.

[0009] With the above structure, when the disc bodies are attached to each other and firmly connected, the sealing ring will be compressed and deformed to seal the gap at the connection, thereby improving the airtightness of the connection and preventing water from overflowing from the connection.

[0010] In a possible implementation, the outer end surface of the sealed ring of one of the disk bodies is provided with a plurality of bite lines with alternating concave and convex shapes, and the outer end surface of the sealed ring of the other disk body is provided with corresponding bite lines.
