                                一、概述Outline

                                QJ(D/S)R3型精小型氣動三通閥是由氣動活塞執行機構和三通球閥組成。改變球芯與管道的相對位置,可以對三條管路流體實現不同的組合控制。
                                      氣動三通閥以壓縮空氣為動力源,接受控制系統的開關信號,通過電磁閥換向,操作球閥按規定要求對管路進行切換。
                                T型三通可使三路正交的管道互相連通,即起分流(合流)作用,也可使其中兩條管道連通而切斷另一條管道。
                                L型三通只能連通互相正交的兩條管道或切換方向,即起分配作用。
                                三通球閥按作用方式分單作用和雙作用兩種形式。單作用的特點是一旦動力源發生故障時,球閥將處于控制系統要求的狀態。

                                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.
