Description

Technical Field

[0001] The utility model relates to a connecting device, in particular to a sliding sleeve type connecting structure used for connecting a valve and a pipeline. Background Art

[0002] In the pipeline system, the connection between valves and pipelines is a key link to ensure the efficiency and safety of fluid transmission. Although traditional valve and pipeline connection methods, such as flange connection and welding, can meet basic connection requirements, they still have many shortcomings in practical applications. For example, flange connection requires flange centering and bolt tightening during installation, which is cumbersome and prone to deviations; welding connection requires preheating, welding and cooling of pipelines and valves, which is a complex process and prone to welding defects. In addition, these traditional connection methods also have certain limitations in terms of sealing performance, corrosion resistance, and disassembly and maintenance.

[0003] Therefore, in order to overcome the shortcomings of traditional connection methods and improve the efficiency and reliability of valve-pipe connection, it is particularly important to develop a new connection structure. Based on this background, we propose a sliding sleeve connection structure for connecting valves and pipelines. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a device for connecting a valve with a pipeline.

[0005] The technical problem to be solved by the utility model is achieved by the following technical solutions:

[0006] A sliding sleeve connection structure for connecting a valve and a pipeline comprises a sliding sleeve, which is sleeved on the connection position between the valve and the pipeline, and the sliding sleeve is fixed on the connection position between the valve and the pipeline by conical flanges and bolts at both ends, and sealing rings are embedded in the inner walls of the left and right ends of the sliding sleeve.

[0007] There is at least one sealing ring embedded in the inner walls of the left and right ends of the sliding sleeve.

[0008] The sealing ring may be made of one of polytetrafluoroethylene (PTFE) and synthetic rubber.

[0009] The sliding sleeves are pre-sleeved on both ends of the valve before connection.

[0010] The beneficial effects of the utility model are as follows: the operation is simple and quick: when installing the sliding sleeve connection structure, it is only necessary to put the sliding sleeve on the connection position of the valve and the pipeline, and then fix the conical flange to the valve and the pipeline by bolts. No complicated welding or flange connection process is required, which greatly simplifies the installation process and improves work efficiency.

[0011] Excellent sealing performance: The inner wall of the sleeve is embedded with a sealing ring, which can effectively prevent fluid leakage at the connection and improve the sealing performance of the connection. At the same time, the sealing ring is made of highly elastic material with good corrosion resistance and wear resistance, which can ensure long-term and stable sealing effect.

[0012] Strong adaptability: The sleeve connection structure is suitable for connecting valves and pipes of various materials and specifications, and has a wide range of applicability. At the same time, due to the design of the sleeve and conical flange, the structure can also adapt to a certain degree of pipeline and valve deviation, reducing the installation accuracy requirements.

[0013] Easy disassembly and maintenance: When the valve needs to be disassembled or replaced, the sleeve and conical flange can be easily removed by loosening the bolts without destroying the structure of the pipeline and valve, which is convenient for subsequent maintenance and replacement.

No complicated welding or flange connection process is required, which greatly simplifies the installation process and improves work efficiency.

[0022] The inner wall of the sleeve is embedded with a sealing ring, which can effectively prevent fluid leakage at the connection and improve the sealing performance of the connection. At the same time, the sealing ring is made of highly elastic material, has good corrosion resistance and wear resistance, and can ensure long-term and stable sealing effect.

[0023] The sleeve connection structure is suitable for connecting valves and pipes of various materials and specifications, and has a wide range of applicability. At the same time, due to the design of the sleeve and conical flange, the structure can also adapt to a certain degree of pipeline and valve deviation, reducing the installation accuracy requirements.
