此系统为防腐手动取样装置。取样物料接触各部件均采用里衬PFA、衬氟材质，达到防腐目的；四氟吸料管配套插入管（衬氟／搪玻璃材质）浸于釜内料液以下，增加其过程的稳定性。通过抽真空将物料在系统中安全、快捷取样。
     This system is an anti-corrosion manual sampling device. The parts in contact with the sampling medium are lined with PFA or Fluorine to achieve anti-corrosion purpose. The Teflon suction pipe matched with the insertion pipe (fluorine lined/ glass lined) is immersed below the medium liquid in the vessel to increase the stability of the process. The medium is sampled safely and quickly in the system by vacuuming.

安装步骤：Installation procedure:
1.将（插入管）安装到反应釜相应管口上紧固螺栓。
Install (the insertion pipe) on the corresponding nozzle of the reactor and fasten the bolts.
2.将取样系统下端（底座）与（隔膜阀1)拆分，将（底座）安装到（插入管）上端。
Separate the lower end (base) of the sampling system from (diaphragm valve 1), and install (base) to the upper end of (insertion pipe).
3.将四氟外翻边（吸料管）装入（底座）内腔，四氟（吸料管）外翻边处于（阀座）密封面处吻合。
Put the Teflon outer flanging (suction pipe) into the inner cavity of the (base), and the Teflon outer flange of (the suction pipe) is matched at the sealing surface of the (valve seat) .
4.将其余取样系统主体与其连接紧固，保证（底座）密封处压紧、无泄漏。
Connect and tighten the rest of the sampling system body to ensure that the sealing part of (base) is tight and without leakage. 
备注：连接设备小口管径时可取消底座部件。
Note: The base part can be canceled when connecting the device with small diameter pipe. 
取样步骤:
Sampling procedure
1.取样前确认、检查：Confirm and check before starting: 
a：所有隔膜阀处于关闭状态。
All diaphragm valves are closed.
b：取样系统内、外无残余物视镜无破损。
There is no residue inside and outside the sampling system, and no damage to the sightglass.
c：真空系统与对应真空接口相连并确保密封无泄漏。
The vacuum system is connected to the corresponding vacuum interface and ensure that the seal is leak-free.
d：反吹用0.2~0.3MPa氮气气源。
0.2~0.3 MPa nitrogen gas source is used for back blowing.
e：备用150/250mL硼硅玻璃取样瓶1支。
One spare 150/250 ml borosilicate glass sampling bottle is needed.

2.吸料：Suction：
a：打开（隔膜阀1)。
Open (diaphragm valve 1) .
b：适时打开（隔膜阀2)。
Open (diaphragm valve 2) in time.
c：观察（视镜）。浮球缓慢上升，充满视镜窗。
Observe (sightglass). The floater slowly rises and medium fills the sightglass window.
d：关闭（隔膜阀1、隔膜阀2)。
Close (diaphragm valve 1 and diaphragm valve 2) .
3.取样：Sampling:
a：打开（隔膜阀3)。
Open (diaphragm valve 3)
b：打开（隔膜阀4)。观察取样瓶量剂。
Open (diaphragm valve 4). Observe the dosage of the sam­piing bottle.
c：关闭（隔膜阀3、隔膜阀4)。
Close (diaphragm valve 3 and diaphragm valve 4). 
d：取下（取样瓶）密封瓶口——装入（备用取样瓶）。

Remove the (sampling bottle) and seal the bottle mouth - put in (spare sampling bottle) 。

e：打开（隔膜阀1)——打开（隔膜阀5)——打开（隔膜阀3、隔膜阀4)。

Open (diaphragm valve 1)—Open (diaphragm valve 5)—Open (diaphragm valve 3 and diaphragm valve 4) .
氮气将系统内残余物料反吹釜内。
Make nitrogen blow the residual medium in the system back into the vessel.
f：关闭（隔膜阀1、隔膜阀3、隔膜阀4、隔膜阀5)。
Close (diaphragm valve 1、diaphragm valve 3、diaphragm valve 4 and diaphragm valve 5) .
g：取祥结束。
Sampling complete.
