　　Multi-way valve compared with JMA many valve controller

　　多路阀系统

　　Multi-way valve system

　　目前，在水的过滤、软化、除盐等工艺中应用的自动控制装置多采用进口的全自动控制多路阀，此阀的设计是将自动控制器(相当于人脑)和执行操作的阀门(相当于人手)合为一体，在一定的条件下虽具有自动、简单的优点，但同时也存在着如下缺点：

　　At present, in the water filtration, softening, desalination technology in the application of automatic control device, such as imported full automatic control of multi-way valve, the design of this valve is automatically performed on the controller (the equivalent of the human brain) and valve (hand), under certain conditions it is automatic, the advantages of simple, but at the same time it still has the following disadvantages:

　　■ 结构复杂，不易拆卸、维修

　　S structure is complex, difficult to remove, maintenance

　　■ 出现问题难被发现，且某个部件出现故障将影响整个系统的正常运行

　　S a problem hard to be found, and some parts failure will affect the normal operation of the whole system

　　■ 厂家的售后服务如不易到位，用户将无法自行维修，情况严重时会造成整个多路阀连同控制器的报废。

　　S manufacturer of after-sales services such as difficult to reach the designated position, the user will not be able to repair, severe cases will cause the abandonment of the multi-way valve, together with the controller.

　　■ 调节性、互换性差

　　S regulatory, poor compatibility

　　北京洁明公司针对用户需求，在分析了解全自动控制多路阀的优缺点后，于2003年研发、生产出自动JMA多阀控制器。

　　Beijing jie Ming company in view of the user requirements, based on the analysis to understand the advantages and the disadvantages of automatic control multi-way valve, in more than 2003 research and development, producing automatic JMA valve controller.

　　这种控制器首先把“脑”“手”的功能分开，“手”的功能采用常规的液动或气动隔膜阀，保持其灵活、简单、稳定的优点，同时，专门设计的控制器又把“脑”的功能大提高。

　　This kind of controller is firstly to separate the function of the "brain" "hand", the function of "hand" of the conventional hydraulic or pneumatic diaphragm valve, maintain its the advantages of flexible, simple, stable, at the same time, the designed controller and the ability to "brain" big increase.

　　JMA多阀控制器工作原理

　　JMA valve working principle of the controller

　　JMA多阀控制器由信号分配器和程序控制器构成，固定于防水控制器外壳内。

　　JMA valve controller made up of signal distributor and program controller, fixed in waterproof controller inside the shell.

　　信号分配器根据程序控制器的设定，驱动小型电机转动(特殊情况 下也可手动旋转)，转至不同位置就有一个或几个孔道打开或关闭。

　　Signal distributor, according to a set program controller to drive the small motor rotation (special circumstances can also be manual rotation), moved to different positions have one or several channel on or off.

　　分配器孔道位置编号与系统运行步骤相对应，被打开或关闭的孔道引导信号压力源驱动隔膜阀动作。

　　Distributor channel position number corresponding with the system operation steps, open or close the channel guide signal pressure source driver diaphragm valve action.

　　驱动隔膜阀的信号压力源为液体或气体，无持续电压，大大减小了由于电器引起的故障与维护工作。

　　Pressure signal source which drives the diaphragm valve for liquid or gas, no continuous voltage, greatly reduced due to electrical fault and maintenance work.

　　各种信号分配器与程序控制器的多种组合设计，可满足各种水处理系统复杂的程序控制要求。

　　Various signal distributor and a variety of combination design of program controller, can satisfy all kinds of water treatment systems, complex process control requirements.

　　JMA多阀控制器功能简介

　　Introduction of JMA valve controller function

　　● 采用纯中文操作界面，参数设定简单明了，操作人员无须掌握复杂的编程语言;

　　Using pure Chinese interface, parameter setting straightforward, operating personnel do not need to master complex programming language;
