气动三通法兰球阀
气动三通法兰球阀是一种结合了气动驱动、三通结构与法兰连接的多功能阀门,主要用于管路系统中实现流体的换向、分流或合流控制。
气动三通法兰球阀结构由阀体、带三通流道的球体(常见L型或T型流道)、气动执行器、阀杆、法兰接口及密封组件等组成。工作时,通过气动执行器接收控制信号(如气压信号),驱动阀杆带动球体旋转,使球体内流道与阀体的不同端口对接,从而快速切换流体通路(例如L型流道可实现两通道间的换向,T型流道可实现一路流体分成两路或两路流体汇合成一路)。
气动三通法兰球阀兼具气动驱动的快速响应、远程控制优势,以及三通结构的多功能性,同时法兰连接方式便于安装与维护。具有流阻小、密封度好、操作便捷的特点,适用于石油、化工、水处理、轻工等行业的自动化管路系统,尤其适合需要频繁切换流体路径的工况。
Product Overview of Pneumatic Three-Way Flanged Ball Valve
The pneumatic three-way flanged ball valve is a multi-functional valve integrating pneumatic actuation, three-way structure, flanged connection, mainly used in pipeline systems to control fluid direction switching, splitting, combining.
Its structure includes a valve body, a ball with three-way flow channels (commonly L-type T-type), a pneumatic actuator, a valve stem, flanged interfaces, sealing components. During operation, the pneumatic actuator receives control signals (such as air pressure signals) to drive the valve stem rotate the ball, aligning the internal flow channel of the ball with different ports of the valve body, thereby quickly switching fluid paths (e.g., the L-type flow channel can realize direction switching between two channels, while the T-type flow channel can split one fluid into two paths combine two fluids into one).
This valve combines the advantages of rapid response remote control pneumatic actuation, the versatility of the three-way structure, the ease of installation maintenance flanged connection. It features low flow resistance, reliable sealing, convenient operation, making it suitable for automated pipeline systems in industries such as petroleum, chemical engineering, water treatment, light industry, especially for working conditions requiring frequent switching of fluid paths.
