Description

Technical Field

[0001] This utility model relates to the field of hydraulically controlled check butterfly valve technology, and more specifically, it relates to a hydraulically controlled check butterfly valve. Background Technology

[0002] A butterfly valve is a common type of industrial valve. Its core component is a disc-shaped closing element (butterfly plate), which can rotate around the valve's axis. When the butterfly plate rotates to be parallel to the pipeline centerline, the valve is fully open, allowing fluid to flow. When the butterfly plate rotates to be perpendicular to the pipeline centerline, the valve is closed, cutting off fluid flow. The butterfly valve's opening and closing element (butterfly plate) is usually driven by the valve stem, and the flow rate of the medium is controlled by its rotation.

[0003] However, most existing butterfly valves cannot be reinforced after installation, which affects the stability and safety of the butterfly valve during long-term use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hydraulically controlled check butterfly valve, which has the characteristics of being able to be reinforced after installation and ensuring the stability and safety of the butterfly valve during long-term use.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides a hydraulically controlled check butterfly valve, including a valve body, a valve body itself inside the valve body, an installation assembly on the surface of the valve body, a support block on one side of the installation assembly, a support frame on one side of the support block, a threaded sleeve inside the support frame, a threaded rod threadedly connected inside the threaded sleeve, a rotating shaft welded to one end of the threaded rod, a clamping plate sleeved to the rotating shaft via a bearing, and a limit assembly between the clamping plate and the support frame.

[0008] When using a hydraulically controlled check butterfly valve based on this technical solution, the support frame can be easily disassembled and assembled by setting up installation components. By rotating the threaded rod and using the threaded sleeve, the threaded rod, rotating shaft, and clamping plate can be moved, facilitating adjustment and control of the clamping plate. This allows for clamping and fixing of the pipeline surface, ensuring the stability of the pipeline and structure during operation. By setting up a limit component, the clamping plate can be limited and supported, ensuring the stability and safety of the clamping plate during movement and adjustment.

[0009] Furthermore, a connecting plate is provided on the surface of the valve body, and a connecting hole is provided inside the connecting plate.

The installation component 5 facilitates the disassembly and assembly of a support frame 6. A support block 13 is provided on one side of the installation component 5, and a support frame 6 is provided on one side of the support block 13. A threaded sleeve 10 is provided inside the support frame 6, and a threaded rod 11 is threadedly connected inside the threaded sleeve 10. A rotating shaft 12 is welded to one end of the threaded rod 11, and a clamping plate 7 is sleeved on the rotating shaft 12 through a bearing. By rotating the threaded rod 11, the threaded rod 11, rotating shaft 12, and clamping plate 7 can be moved with the help of the threaded sleeve 10, facilitating the adjustment and control of the clamping plate 7. This allows for clamping and fixing of the pipe surface, ensuring the stability of the pipe and structure during operation. A limit component 8 is provided between the clamping plate 7 and the support frame 6, providing limit support for the clamping plate 7 and ensuring its stability and safety during movement and adjustment.
