Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of knife gate valves, in particular to a flow regulating knife gate valve. Background Art
[0002] Knife gate valves are widely used in pipeline systems in industries such as chemical, papermaking, and sewage treatment to control the flow of media. They are especially suitable for intercepting sewage pipes that carry mud, stones, wood blocks, and strips of fiber. Since the gate disc is designed as a flat structure, it will be subjected to large bending forces during use. In order to effectively protect the gate disc, the current gate valve design is mainly limited to the interception function, that is, it can only achieve two states of fully open or fully closed, and cannot finely control the flow. However, in some scenarios where flow control is required, although other types of valves are considered, these valves are often bulky and costly. In view of this, in-depth research on the above issues has led to the creation of this case. Utility Model Content
