Description

Technical Field

[0001] The utility model relates to the field of valves, and more specifically, to a valve interface structure. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium (temperature, pressure, and flow). Based on their function, they can be categorized as shutoff valves, check valves, and regulating valves. Valves are control components in fluid conveying systems, performing functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, and overflow pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from the simplest shutoff valve to the most complex valves used in automated control systems.

[0003] However, when valves in the prior art are connected to connecting pipes, they are usually connected through threaded connections or flange connections. When connected through threaded connections, it is easy to cause poor sealing between the valve and the connecting pipe, resulting in leakage at the connection between the valve and the connecting pipe, causing safety hazards and waste. To address this problem, it is necessary for technicians in this field to develop a valve interface structure. Utility Model Content
