Q45F三通法兰球阀有T形和L形。T形能使三条正交的管道相互联通和切断第三条通道，起分流、合流作用。L形只能连接相互正交的两条管道，不能同时保持第三条管道的相互连通，只起分配作用。

Q45F三通法兰球阀产品特点：

       1、三通球阀在结构上采用一体化结构，4面阀座的密封型式，法兰联接少，稳定性高，设计实现了轻量化。
       2、三通球芯分T形和L形，使用寿命长，流通能力大，阻力小。
       3、球阀按作用式分单作用和双作用两种型式，单作用式的特点是一旦动力源发生故障时，球阀将处于控制系统要求的状态。

三通法兰球阀

三通法兰球阀是一种具有三个通道的球阀，采用法兰连接方式，通过球体的旋转实现不同通道间的流体切换或分流、合流功能。其核心结构包括阀体、带三个端口的球体、阀杆、法兰接口及密封组件等。

三通法兰球阀工作时，通过旋转阀杆（手动或驱动装置控制）带动球体转动，使球体内部通道与阀体的不同端口对接，可实现多种通路组合（如L型通路实现两通道切换，T型通路实现分流或合流）。

三通法兰球阀具有结构紧凑、流通阻力小、密封性能好的特点，能适应多种介质（液体、气体等），且法兰连接方式便于安装和维护。广泛应用于石油、化工、水处理、暖通等行业的管路系统中，用于介质的换向、分流控制。

Product Overview of Three-Way Flanged Ball Valve

The three-way flanged ball valve is a type of ball valve with three ports, adopting a flanged connection. It enables fluid switching, splitting, combining between different channels through the rotation of the ball. Its core structure includes a valve body, a ball with three ports, a valve stem, flanged interfaces, sealing components.

During operation, the valve stem (controlled manually by an actuator) rotates to drive the ball, aligning the internal channel of the ball with different ports of the valve body. This allows various通路 combinations (e.g., L-type channel for switching between two channels, T-type channel for splitting combining flows).

This type of valve features a compact structure, low flow resistance, excellent sealing performance, adaptable to various media (liquids, gases, etc.). The flanged connection facilitates installation maintenance. It is widely used in pipeline systems of petroleum, chemical, water treatment, heating, ventilation industries for medium direction switching flow splitting control.
