Description

Technical Field

[0001] The utility model relates to the technical field of loose flanges, and particularly relates to a loose flange for ocean engineering. Background Technique

[0002] A loose flange is a common pipe connection component, which has the characteristics of simple structure, convenient installation and maintenance. In ocean engineering, due to the harsh environment, higher requirements are imposed on the strength and corrosion resistance of the flange.

[0003] When the traditional loose flange is in use, there is a lack of a support structure at the bottom of the flange disc. Especially in the ocean environment, the flow of seawater and the wind and waves will have an unstable impact on the structure, resulting in insufficient connection strength. Therefore, a loose flange for ocean engineering is proposed.

[0004] A kind of rigid-inserted loose flange for ocean engineering disclosed in the publication number CN219473004U. Although, this rigid-inserted loose flange for ocean engineering includes a flange disc, a reinforcing groove is opened on one side of the flange disc, a steel plate is fixedly installed in the reinforcing groove, a number of fixing screw holes are opened on the other side of the flange disc, and a number of positioning screw holes equal to the fixing screw holes are opened on the side of the steel plate close to the fixing screw holes. The flange disc is installed with fixing screws through the fixing screw holes and the positioning screw holes. Beneficial effects: Steel plates and reinforcing components are respectively added to the butting surfaces of the flange disc and the flanged flange, thereby increasing the strength of the loose flange after the butting surfaces are butted, increasing its service life, and further increasing the service performance. The stability of the flanged flange in the flange disc is increased through the fixing components.

[0005] Although the above patent has achieved adding steel plates and reinforcing components to the butting surfaces of the flange disc and the flanged flange respectively, thereby increasing the strength of the loose flange after the butting surfaces are butted, increasing its service life, and further increasing the service performance, and increasing the stability of the flanged flange in the flange disc through the fixing components; however, the sealing performance of this device is poor, there is a lack of a support mechanism inside the sealing ring, and the sealing performance will decrease after long-term use of the sealing ring. The support mechanism can help the sealing ring better adapt to the surface of the pipeline or equipment, thereby improving the sealing performance.

[0006] Therefore, it is very necessary to invent a loose flange for ocean engineering to solve the above problems. Content of the Utility Model

[0017] (3) Beneficial effects

[0018] The utility model provides a loose flange for ocean engineering, which has the following beneficial effects:

[0019] 1. For the loose flange used in ocean engineering, through the settings of the support mechanism, grounding pestle, buffer mechanism and buffer spring, when in use, after rotating the telescopic support rods on both sides of the support plate to appropriate positions, the length of the telescopic support rods can be changed using the limit posts. Then, place the connection block on one side of the fixed rod on the ground and apply pressure to the surface of the connection block, so that the grounding pestle at the bottom of the connection block penetrates into the ground, which can provide additional support force for the equipment on both sides. Secondly, when an external force acts on the interface, a downward impact force will be generated. At this time, the four damping hydraulic rods drive the buffer springs sleeved on the surface to contract, generating a reverse force to relieve the impact force above, achieving the effect of buffering and shock absorption, and avoiding the unstable influence of seawater flow and wind and waves on the flange, resulting in loosening at the flange interface.

[0020] 2. For the loose flange used in ocean engineering, through the setting of the sealing mechanism, when docking the flange and the pipeline, insert the two ends with sealing rings into the pipeline. Since there is a support spring inside the sealing ring, the sealing ring will firmly fit the surface of the pipeline, thereby improving the sealing performance of the sealing ring, reducing the friction and wear between the sealing ring and the surface of the pipeline or equipment, thus extending its service life and reducing the maintenance cost.
