Description

Technical Field

[0001] The utility model relates to the technical field of half joints, and more particularly to a steel half joint. Background Art

[0002] In existing technologies, when connecting pipes, traditional steel half joints may not be completely and tightly fixed on both ends of the pipes in some cases due to improper installation or slight deformation of the pipes, resulting in a loose sealing surface, which in turn leads to problems such as water leakage and air leakage.

[0003] In actual applications, the process of connecting two pipes with existing steel half joints is not always simple and quick, especially in complex piping systems or narrow spaces. It often requires a lot of manpower and time to complete the connection. Many traditional half joints require the use of multiple bolts, nuts and other fasteners for connection. The installation process requires alignment and adjustment, and the operator needs to have certain skills and experience.

[0004] In practical applications, especially when pipelines need to be repaired or temporarily connected, the unstable placement of the pipeline often affects the fixing process of the half joint, resulting in a loose connection. Since the pipeline may have a certain displacement or deformation, the half joint cannot be accurately docked with the pipeline interface, which makes the connection process difficult and even affects the stability and sealing of the pipeline.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a steel half joint with the following beneficial effects:

[0018] 1. The connection component is detachably connected to the first tube body and the second tube body, which facilitates the assembly and disassembly of the equipment. In particular, the coordinated design of the boss and the sealing groove not only ensures the firmness of the connection, but also improves the convenience of installation. The design of the insertion platform and the insertion groove enables more precise docking between the sections, which improves the stability and sealing of the connection. The coordination of the fixing groove and the fixing platform further enhances the firmness of the connection and avoids loosening due to vibration or external force during use.

[0019] 2. The design of the sealing assembly, especially the use of the sealing sleeve and the rotating ring, can effectively prevent medium leakage and ensure the safety and efficiency of the equipment during operation. The close fit between the sealing sleeve and the sealing groove and the sleeve design of the rotating ring can ensure the reliability of the seal. The sealing sleeve and the rotating ring used in the sealing assembly have strong adaptability and can effectively maintain the sealing performance under different working conditions. Especially when the pipeline needs to withstand a certain pressure or temperature fluctuation, it can provide long-lasting sealing protection.

[0020] 3. The stabilizing component can effectively stabilize the pipeline and its connecting parts through the cooperation of the fixing plate, rubber pad and fixing sleeve to prevent deformation or damage caused by external force during transportation or use. The rubber pad can play a buffering role and reduce the impact of external vibration on the equipment. The design of the fixing bolts and gaskets ensures that the stabilizing component can withstand greater pressure during the tightening process. At the same time, the gasket plays a protective role, avoiding direct friction between the bolts and other components, reducing wear and damage. BRIEF DESCRIPTION OF THE DRAWINGS
