Position Indicator 

一.概述  General description

FT-10 型液压控制阀开度指示器是一种用于指示液压遥控阀门的开启度的装置。通过开度指示器内部测量室的椭圆齿轮流量计对阀门动作液压流量的计数,由齿轮旋转来驱动脉冲发生器,以电子计数值转换成液压控制阀的开启度信号。该阀位信号既可从指示器本身的指示面板上直接读出, 又可以通过电控柜以4-20mA电流形式或RS485总线通信输出以满足液压系统的不同的阀位信号的需要。

 

TypeFT-10 Valve Position Indicator of Hydraulic Controlled valve is one kind of opened angle indication meter for hydraulic remote control valve. The hydraulic flow for driving valve is counted by oval gear flow meter in the measuring chamber, and the rotating of this oval gear is being activated the pulse generator, therefore the valve position signal is produced by conversion from the counting of the pulse generator. This valve position signal can not only be read directly from indicator itself, but also can be output to hydraulic system by 4-20mA current or RS 485-bus cable to meet the deferent requirement from system.

四.使用说明  Help for use

1. 安装调试:Installation and commissioning

注意:在现场调试前,必须检查全部液压管路的清洁,以免液压管路内的垃圾和其他杂质进入指示器或电磁阀,使系统不能正常工作。

 

A. 接入液压系统:把“IN”接口接入液压动力油进口,“OUT”口接上执行器进油口;当液压动力油通过阀位指示器后,阀位指示器仪表盘指针顺时针旋转显示通过的液压油流过的总容积,直到液压动力油充满执行器后,阀位指示器指针停止转动,此刻指针显示的位置即为阀门打开的位置。(备注:不同大小的执行器显示的容积不同)。同理,当执行器关闭时,阀位指示器的指针会逆时针旋转恢复0位,即显示执行器已关闭。

B. “0”调整:由于初次接入液压系统时液压管路的容积和管路及执行器中空气的影响,往往执行器在关闭时阀位指示器的指针回复不到“0”位;此时应反复打开和关闭执行器若干次,待执行器和管路中的残余空气排尽后,揿下阀位指示器面板上的铜按钮,把指针调回“0”位。

 

Note: Before adjusting on site, it must check with the cleanness of all hydraulic pipe lines in order to avoid the refuse and other impurities in the pipe lines coming into the indicator or the solenoid valve and thus the system cannot function properly.

 

A . Connect hydraulic system: the" IN"port connected to the hydraulic power oil imports," OUT" port connected to the actuator oil inlet; when the hydraulic power oil through the valve position indicator, valve position indicator panel rotating display through the hydraulic oil flowing through the total volume, until the full implementation of hydraulic power oil converter, valve position indicator pointer stops rotating, now pointer indicating the location of the valve open position. ( Note: depending on the size of the actuator to display different volume ). Similarly, when the actuator is closed, the valve position indicator pointer will rotate counterclockwise recovery “0”, whereby the display actuator has been closed.

B.  "0"position to adjust: due to the initial access of hydraulic system of hydraulic pipeline volume and pipeline &actuator air effects,  when the actuator is closed the valve position indicator cant pointer back to"0" position;so the actuator should be repeatedly opened and closed several times until theactuator and pipeline residual air exhaust, press the valve position indicator on the panel copper button, move the pointer to the "0"position.

 

2. 正常使用: Normal use

 

在平常使用中,液压控制阀开度指示器具有记忆功能,甚至在整个阀门遥控系统失电或者系统电源切断情况下。当电源恢复后,液压控制阀开度指示器仍旧显示阀门原来的开启度。

 

注意: 在操作阀门遥控系统中任何一个阀门时,当指示器上指示阀门到达位置后,操作开关必须停留12分钟,使阀门确实到位,这样可以消除误差。

 

In normal use, the valve position indicator has the feature of memory function even after power failure of whole valve remote control system or system power switched off. The position indicator still displays primary position indication after the power supply switches on again.

 

Note: During operation any valve of valve remote control system, the operating switch should be put at the required position for 1~2 minutes after the required valve position is indicated on indictor. The purpose is to ensure that the valve is reached indeed at this position and eliminate the errors.

 

3. 对液压遥控阀门进行应急操作后的恢复  

Indicator re-setting after emergency operation for hydraulic remote control valve

 

如果用应急操作手动泵对液压遥控阀门操作后,阀门的开启度改变,使实际的阀门开启度与指示的不一致。此时,仅仅需要将该阀门从全关闭→全开启→全关闭,操作一个周期;然后调整“复位铜按钮”令指针归“0”,该指示器就恢复原来正常的工作状态。

 

The position indication shall be differed from valve actual position after valve emergency operation by hand pump and the valve position changed. In this case, the valve should be operated for one cycle from full close to full open and from full open to full close againthen move the pointer to the "0"position.  the position indicator will be recovered to original normal working condition.
