Part includes filling valve and fills goat's horn, and tap has oxygen to return on the body that main pipeline is located between liquid main valve and liquid valve
Closed tube road, it is sequentially installed with along oxygen recovery direction on oxygen recovery pipeline and fills goat's horn, fills service valve assembly and return-air valve.
One end of reflux pipeline described in the utility model connects with liquid oxygen storage tank, the other end and main pipeline of reflux pipeline
Connection, return valve is mounted at the both ends of reflux pipeline.
The service valve assembly described in the utility model that fills is comprised at least for detecting the analysis valve of liquid oxygen purity, for clear
Except the blow through valve of foreign gas in pipeline and for preventing the too high safety valve of pipeline pressure.
Main pipeline described in the utility model is located between liquid main valve and oxygen recovery pipeline and liquid valve and Low Temperature Liquid
Body between oxygen pump is the bellows for eliminating stress.
General principle of the utility model in terms of oxygen recovery be：Oxygen in tank car on oxygen recovery pipeline through filling
Analysis valve in service valve assembly B detects to its purity, after detection purity meets recovery requirement, because groove tank pressure is more than
The pressure of liquid oxygen storage tank, for oxygen in the presence of pressure differential, oxygen is by oxygen recovery pipeline, main pipeline and goes out the entrance of liquid main valve
In liquid oxygen storage tank, because liquid oxygen temperature is extremely low in liquid oxygen storage tank, oxygen is cooled after liquid oxygen storage tank is entered, becomes liquid oxygen naturally；
In removal process, with being continuously increased for oxygen recovery amount, the liquid oxygen temperature in liquid oxygen storage tank can gradually rise, and now, need
Liquid nitrogen cooling is utilized in reservoir surface, to ensure the pressure and temperature in liquid oxygen storage tank.
The advantage that the utility model possesses is：
1st, oxygen recovery pipeline is installed additional in traditional fill of liquid oxygen system, to needing discharge to slattern in conventional liquid oxygen tank car
Oxygen reclaimed, solve in traditional handicraft the significant wastage phenomenon to caused by oxygen, meanwhile, it also avoid high pressure tank car
Potential safety hazard caused by oxygen discharge；
2nd, for there was only the present situation of single charging joint in conventional liquid oxygen charging system, the utility model fills in conventional liquid oxygen
According to actual production demand on the basis of dress system, multiple charging joints are added, substantially increases and fills efficiency, reduce groove
Car fills waiting time, improves productivity effect；
3rd, the utility model technical pattern is simple and practical, ingenious in design, spends lower cost to be improved traditional handicraft,
More obvious effect is achieved, brings great economic benefit to enterprise, cost performance is notable.
