进口电动内螺纹三通球阀有两座和四座密封结构，阀芯孔道有L型和T型两种结构形式，采用控制阀芯旋转角度，改变阀芯孔道与管道口的连接状态，可实现对三条支管不同的组合控制

retz The imported electric internal thread three-way ball valve has two and four sealing structures, and the valve core port has two types of structure: L-shaped and T-shaped. By controlling the rotation angle of the valve core and changing the connection state between the valve core port and the pipeline port, different combinations of three branch pipes can be controlled

功能介绍 Function introduction

进口电动内螺纹三通球阀配置角行程电动执行机构，以AC220V、AC380V或DC24V电源电压作动力，接受工业自动化仪表控制系统输入的（4-20mA、或1-5VDC）电流信号或电压信号，即可控制运转retz The imported electric internal thread three-way ball valve is equipped with an angular stroke electric actuator, which is powered by AC220V, AC380V or DC24V power supply voltage and receives (4-20mA, or 1-5VDC) current signal or voltage signal input from the industrial automation instrument control system to control the operation

L型流道的三通4面阀座球阀，采用2面阀座，受力平衡，保证闭止通道的可靠密封。主要用于流路的换向 Three-way four-side valve seat ball valve with L-shaped flow passage adopts two-side valve seat, with balanced stress, to ensure reliable sealing of the closing channel. Mainly used for commutation of flow path

T型流道的三通4面阀座，由于采用4面阀座，亚力平衡，保证闭止通道的可靠密封。主要用于分流、混 流、换向以及三通道的完全开放 The three-way four-face valve seat of the T-shaped flow passage is balanced by Yali due to the four-face valve seat, which ensures the reliable sealing of the closing channel. It is mainly used for shunt, mixed flow, commutation and full opening of three channels
