一， 概述
   UQK-65-C系列船用浮球液位控制器（以下简称控制器）。它山浮球，连杆，铁心部分和磁性开关发生转换机构组成，由浮球检测到的液位变化直接传给磁性开关转换机构。控制器合理地选用全密封引磁隔离开关转换机构，使永磁元件不能直接接触介质，避免了介质内部的混杂蚀质引起轧熬和卡死现象，也不因机构的摩擦而发生故障。
   控制器还符合国际电工委会（IEC）92-504（1974年）船用电器设备器特殊要求-控制和测量仪表，中华人民共和国船舶检验局（1983）钢质海船入级与建造规范有关规定，部分还符号英国劳氏船级社的控制和电器设备的形式认可实验规则（1975年）。
二， 用途
   UQK-65-C系列位控制器广泛适用于海洋船舶及其它设备的机舱副机锅炉等装置的润滑油，燃油，废油，淡水，污水等密闭或开口容器内的液位报警和控制的作用。但不适宜于对不锈钢材料起腐蚀作用和易燃，易爆的流体的危险场所。
三， 主要技术参数
1. 控制作用；单点位式
Ⅰ，BRIEF
  Marine Floating Ball Liquid Level Controlleru (calledcontroller in following),is made up of the floating ball theconnccting rod,iron core party and the maghetic switching mechanismThe Liquid Level change checked by the floating ball will bedircctiy sent to the magnetic switching mechanism The controllerresonably selects sealing magnetic isolated on-off switchingmechanism in order that the permnnent-magnet component donitdircctly contact the agent So there aren’t both rolling stop andstoping machine by the mixed impurity of the internal agent and tooccur the stoppage for the mechanical frictiou of themcchanism
  The controller also meets the special requirment of marinecontrol and mcasurement instruments provided by IEC 92-504(1974)ofthe Intenational Elcctical Industrial committee and is up to theSteel Structure Ocean Ship Classification and the relativestipulations on the marine measurement instrument of MarineInspection Bureau of the People’sRepublic of China,and is partallyup to the test rules on control and electric equipment for modelacceptance of Lioyd’s Register of Shipping
Ⅱ,APPLICATION
  Marine Floating Ball Level Controllcr seriesUQK-65-C,iswidciy used in Ocean Ships and various closevessele andopenvessels for liquid level alarm of control in other equipmentfor lubicating-oil,kerosene of waste oil fresh water,industialwaste water ctc in auxiliary machine boiler in engine room of aship But the controller is not suitable for the agent corrosive tostainless and in the explosive and inflammable dangeroussites
Ⅲ,MAIN TECHNICAL PARAMETER
1. Control function;single-point position

   控制器工作原理基于阿基米德定律，即浮球在液体里受到向上的浮力，浮力的大小等于浮球所排开液体的重量。随着容器内液位的变化，浮球随之上下运动，从而带动连杆，铁心上下移动，使铁心与磁钢的相对位置发生变化。通过铁心与磁钢相互磁力的作用磁钢微动开关转换机构翻转，使微动开关动作，切换差约10-40或10-70mm如图-所示。该微动开关可来操作报警器，阀门或控制其他装置。
五， 结构及外型尺寸（见图二，图三）
   端子接线图见图四,图四中在低位时，触电C和B之间的线路导通，而触电C和A之间的线路断开。在高液位时触电C和B之间的线路断开，而触电C和A之间的线路接通。

Ⅳ，WORKINGPRINCIPLE
  The controller’s working principle is based on theArchimedes’principle,I,e the floating ball immersed in the liquid aupward floatage which is equal to the liquid weight drained off bythe fioating ball,With the variation of the liquid level in thevessels,the floating ball will go up anddown and drive theconnecting rod and the iron core to move upwards anddownards,andmake the relative position to chang between the ieoncore and the magntic steel,The funcion of magnetic between ironcore and the magentic steel makes the minatre on-off switchingmechanism turn over and makes the switch act,the changing overdifference about 10-40mmof 10-70mmshown in fig,The miniature seitchwill send a signal to realize level alarm,to operate the valve,tocontrol other equipment.

七，安装使用
1. 控制器在使用前，应检查各部位是否有磨擦和螺钉松动现象。
2. 控制器必须安装在易观察，维修方便的部位上，并要保持连杆的中心线垂直。
3. 被控制介质液面的波动频率不宜太大。
4. 当被控介质粘度较大，容易结晶的介质不宜使用。
5. 控制器不适宜于对不锈钢材料起腐蚀作用和易燃易爆的流体的危险场所。

Ⅶ.ERECTION AND USAGE
1. Before mounting the controller,the controller should be examindin order to make sure that there is ont any fricion ofscrew-loosing.
2. The controller should be mounted in the position where it iseasy to observe and con-venient for maintenance,And the verticalityof the connecting fod centreline should be main-tained.
3. The frequency and the amplitude of the level fluctuation of theagent measured shouldn’t be too much.
4. When the viscosity of the agent measure is rather high of whenthe agent is easy to becrystallized,the controller is notavailable.
5. The controller is not suitable for the agent corrosive tostainless steel and in the ex-plosive and inflammable dangeroussites.
Ⅷ.ORDER GUIDE
1. When you place an order,please specify the type,the name,themeasure scope,the pressure,the temperature and the specifv gravityof agent.
