进口三阀组德国洛克广东地区畅销

一、进口三阀组结构作用：

三阀组是在安装和撤除的时候,需要用到平衡阀.否则,差压的量程一般很小,如果厂家的过载能力不强,很容易损坏,在流量传感器仪表接入工艺管道时要用“三阀组”，作用是：

1、在管道由初始状态（空）加入介质时，传感器两侧压力会突然变化，压差增大，为避免，应先关闭传感器两侧的阀A、B，打开旁通阀C；

2、在介质充满管道，并趋近平稳、平衡后，逐渐打开A、B，使传感器两侧均匀施加压力；

3、*关闭阀C，传感器开始正常工作；

4、关闭顺序与上述情况相反。此外，三阀组还有其它作用，如运行一段时间后清洗管道，传感器部分不受影响（管路被旁通）

二、进口三阀组描述：

德国《DE LOCKE》洛克进口三阀组可配接：3051、3095、1151、EJA、FX-2、FCX-A/C及霍尼韦尔ST3000系列等变送器,由阀体、二个截止阀及一个平衡阀组成,差压变送器投入运行时的操作程序,打开差压变送器上两个排污阀，而后打开平衡阀，再慢慢打开二个截止阀，将导压管内的空气或污物排除掉,关闭二个排污阀，再关闭平衡阀，变送器即可投入运行。 差压变送器零点在线校验操作程序：先打开平衡阀，关闭二个截止阀，即可对变送器进行零点校验。

Inlet three valve manifold

一、 The structure and function of imported three valve manifold are as follows:
The three valve group needs to use the balance valve when installing and removing. Otherwise, the range of differential pressure is generally small. If the overload capacity of the manufacturer is not strong, it is easy to damage. When the flow sensor instrument is connected to the process pipeline, the "three valve group" should be used. Its function is to:

1. When the medium is added into the pipeline from the initial state (empty), the pressure on both sides of the sensor will change suddenly, and the pressure difference will increase. To avoid this, the valves a and B on both sides of the sensor should be closed first, and the bypass valve C should be opened;
2. After the medium fills the pipe and approaches stable and balanced, gradually open a and B to apply pressure evenly on both sides of the sensor;
3. Finally, close the valve C and the sensor starts to work normally;
4. The closing sequence is the reverse of the above. In addition, the three valve group has other functions, such as cleaning the pipeline after a period of operation, and the sensor part is not affected (the pipeline is bypassed)

二、 Description of inlet three valve manifold:
The imported three valve manifold of German "de Locke" can be matched with: 3051, 3095, 1151, EJA, FX-2, fcx-a / C and Honeywell ST3000 series transmitters, which are composed of valve body, two stop valves and one balance valve. The operation procedure of differential pressure transmitter when put into operation, Open the two blowdown valves on the differential pressure transmitter, then open the balance valve, and then slowly open the two stop valves to remove the air or dirt in the pressure pipe, close the two blowdown valves, and then close the balance valve, and the transmitter can be put into operation. Differential pressure transmitter Zero online calibration operation procedure: first open the balance valve, close the two stop valves, then the transmitter zero calibration.
