QJ（D/S）R3型精小型气动三通球阀，气动三通球阀概述Outline

QJ（D/S）R3型精小型气动三通球阀是由气动活塞执行机构和三通球阀组成。改变球芯与管道的相对位置，可以对三条管路流体实现不同的组合控制。
该产品以压缩空气为动力源，接受控制系统的开关信号，通过电磁阀换向，操作球阀按规定要求对管路进行切换。
T型三通可使三路正交的管道互相连通，即起分流（合流）作用，也可使其中两条管道连通而切断另一条管道。
L型三通只能连通互相正交的两条管道或切换方向，即起分配作用。
三通球阀按作用方式分单作用和双作用两种形式。单作用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。

QJ （D / S） R3-type small air-way ball valve is fine by the pneumatic piston actuator and ball valve components. Change the ball core and the relative position of pipes, pipe flow can be achieved for three different combinations of control.
The product is compressed air as power source, the control system switches the signal received by reversing solenoid valve, operating valve piping according to requirements of the switch.
Three three-way T-orthogonal channel can connect with each other, that divert traffic （mixing） effect, which can also cut off the two tubes connected and another pipeline.
L-type links connecting only two mutually orthogonal channel or switch directions, that is, from the distribution function.
Three way ball valve according to the role of single and double acting points in two forms. Once the role is characterized by a single power source fails, the ball will be in the state of the control system requirements.
