Portable nitrogen purging, leakage detection, vacuum pumping and inflation device and application method

Abstract

A portable nitrogen purging, leakage detection, vacuum pumping and inflation device is characterized by comprising a nitrogen source, a pressure adjuster, a control box and plastic gas pipelines, all of which are sequentially connected, and the control box regulates and controls the whole set. The nitrogen source, the pressure adjuster, the control box and the two plastic gas pipelines are placed in a packaging box. During using, the nitrogen source and the pressure adjuster are connected with the control box. An upper path system of the control box is provided with a gas path interface I and a gas path interface II, wherein the gas path interface I is connected with an inflation valve through the corresponding plastic gas pipeline, and the gas path interface II is connected with a to-be-detected photoelectric device through the corresponding plastic gas pipeline. The control box is further provided with a digital pressure gauge, a three-position gas flow distribution valve, an intelligent vacuum pump, a power switch and power display lamps. The portable nitrogen purging, leakage detection, vacuum pumping and inflation device has the beneficial effects that a miniature, modular and flexible assembly manner is adopted, and multiple functions integrating purging, vacuum pumping, leakage detection and nitrogen inflation are achieved; and parts can be conveniently and flexibly replaced, and the performance of the whole set is changed and improved.

Description

Technical field [0001] The invention relates to a nitrogen purging device of a photoelectric device, in particular to a portable nitrogen purging, leak detection, vacuuming and charging device. Background technique [0002] Optoelectronic instruments and devices, such as visible light observation cameras, low-light night vision, red-look sight imaging and laser instruments, are often used in the field and have to withstand harsh environments such as wind, sand, rain and snow. Generally, these optoelectronic devices will have gas leakage, pollution and condensation during the use process, which will cause the image quality to decline and lead to use errors. To keep it in a good working condition, it must be dust-proof, moisture-proof, anti-condensation, anti-mold, anti-high voltage breakdown, anti-rain, anti-wind and sand to ensure the image quality of the optical system and the stable operation of the electronic circuit, so that it can See clearly, see far. The effective mainte...

AI Technical Summary

Problems solved by technology

The front nitrogen charging vehicle uses large industrial gas cylinders, which are heavy and cannot be carried around. It can only be filled with nitrogen, and the inflation pressure is difficult to control accurately, and may even damage the internal parts; Difficult to control, affecting drying degree and image quality, and can only be done indoors
