Description

Technical Field

[0001] The utility model relates to the technical field of flat plate valves, in particular to a manual flat plate valve regulating structure with a buffer component. Background Art

[0002] A manual gate valve, also known as a manual flat plate valve, is a common valve type primarily used to regulate fluid flow in pipeline systems. Its key feature is that a handwheel or handle controls the upward and downward movement of the valve disc, thereby opening and closing the flow in the pipeline. Below are some basic features and instructions for use of manual flat plate valves: Structural Features: A manual flat plate valve typically consists of a valve body, valve seat, valve disc, valve stem, and handwheel. The valve disc is a flat, disc-shaped component. When it is parallel to the valve seat, the valve is closed; when it is perpendicular to the seat, the valve is fully open. Working Principle: Rotating the handwheel or handle rotates the valve stem, which in turn moves the valve disc up and down. Lifting the valve disc opens the valve, allowing fluid to flow; depressing it closes the valve, preventing fluid flow. Applications: Due to its simple structure, easy operation, and excellent sealing performance, manual flat plate valves are widely used in pipeline systems in various industries, including the petroleum, chemical, water conservancy, power, pharmaceutical, and food industries, to shut off or regulate the flow of media. When selecting and using manual flat valves, appropriate materials and specifications should be selected according to specific working conditions to ensure the reliability and service life of the valve.

[0003] In the prior art, during the use of some manual flat valves, whenever the manual flat valve is opened and closed, the liquid inside the water pipe will instantly impact the pipe wall. If no external buffering intervention is performed during this process, the risk of the pipe wall rupture will increase in the long run, thereby causing dangerous accidents. Some manual flat valves are provided with buffer devices, but the buffer devices of the manual valves only act on the outside of the pipe wall, but cannot act as a buffer on the inside of the pipe wall. The external buffer devices of some pipe walls are not convenient to disassemble, so whenever the manual flat valve and the water pipe connected to it need to be inspected and repaired, it takes a long time to disassemble and install, thereby reducing the overall inspection efficiency.
