Abstract

The utility model relates to an air dew point detecting pipeline which comprises a capacitive dew point detector, wherein an air inlet of the capacitive dew point detector is connected with at least two air path pipelines used for detecting the air dew point of a monitoring point; a switching valve used for controlling on/off of the air path pipeline is arranged on each air path pipeline. According to the air dew point detecting pipeline, the at least two air path pipelines are connected with the air inlet of the capacitive dew point detector; during detection, only the switching valve of one air path pipeline arranged at the monitoring point needs to be turned on, and the air dew points of different monitoring points can be detected through different air path pipelines, so that the utilizing efficiency and the detecting efficiency of the dew point detecting device are improved.

Description

Air dew point signal piping
Technical field
The utility model belongs to checkout equipment technical field, relates to a kind of signal piping for lithium battery workshop air dew point checkout equipment.
Background technology
The detection of lithium battery workshop air dew point at present is generally used moisture detection probe, and this probe is fixed on the position that needs detection, detects primary data and is transferred to data acquisition module by the data line on probe, after treatment, forms dew point data.This detection probe has an open defect: insensitive to air dew point variation, even if air dew point changes, show that numerical value still remains unchanged, and this can cause the control of lithium battery workshop air dew point to lose efficacy, and then affects the quality of production of lithium battery.In order to overcome these drawbacks, adopt condenser type dew point detecting device to act on behalf of detection probe, make the accuracy of accuracy of detection and data higher, but this mode is all to detect a monitoring point to build primary system, very inconvenient, and once can only detect a monitoring point, efficiency is lower.
Utility model content
The purpose of this utility model is to provide a kind of air dew point signal piping, builds primary system and can only detect an inefficient problem in monitoring point to solve existing condenser type dew point detecting device.
For achieving the above object, air dew point signal piping of the present utility model, comprise condenser type dew point detecting device, the air intake of described condenser type dew point detecting device is connected with that at least two-way is for detection of the gas path pipe of monitoring point air dew point, and each gas circuit pipeline is provided with the switch valve for controlling gas path pipe break-make.
The front end of described each gas path pipe is equipped with air boost pump.
Described air boost pump and the gas path pipe length detecting between mouth are less than 2m.
Described air boost pump is membrane pump.
The air intake of described condenser type dew point detecting device connects each gas path pipe by bus-bar.
Described each gas path pipe is polishing pipeline in stainless steel.
The interior diameter of described each gas path pipe is 4~8mm.
Described switch valve is pneumatic valve.
Gas path pipe length between described air boost pump and pneumatic valve is less than 50m.
Air dew point signal piping of the present utility model, tow channel gas road pipeline is at least connected with the air intake of condenser type dew point detecting device, in the time detecting, only the switch valve of a certain gas path pipe of being located at monitoring point need be opened, realize the detection to different check point air dew points by different gas channels, improved utilization ratio and the detection efficiency of dew point checkout equipment.
