Abstract
A liquefied petroleum gas filling device of the utility model belongs to the technical field of liquefied petroleum gas filling equipment, comprising two sets of liquid gas cylinders. Gas phase ports of the two sets of cylinders are respectively connected in parallel with two gas phase tubes and one end of the gas phase tube is enclosed. Liquid phase ports of the two sets of cylinders are connected in parallel with a liquid phase tube whose one end is enclosed. The other end of the gas phase tube is connected with a compressor by a four-way valve, and the other end of the liquid phase tube is connected with a filling tube with a valve. Every set of the cylinders comprises four cylinders. Manometers are arranged on the gas phase tubes. A safety valve is arranged on the liquid phase tube. The valves are arranged on the gas phase ports of the cylinders, the liquid phase port, the gas phase tubes, the liquid phase tube and a communication tube. The utility model is convenient to fill liquid gas in towns and countries.
Description
Technical field
The utility model belongs to liquefied petroleum gas (LPG) filling apparatus technical field, particularly a kind of liquefied petroleum gas (LPG) charging device that the civil liquefied gas bottle is filled of being suitable for.
Background technique
Liquid gas calorific value height, deposit the health little, easy to use that takes up space, do not had the natural gas supply area common people to welcome deeply.But, liquid gas is inflammable, explosive, volatile, storage and transportation are very limited, generally be large-scale liquefied gas tank to be set in large-scale liquefied gas station, utilize connected charge gun to give the end user's who collects in advance empty liquefied air bottle inflation, again the reality bottle of breaking through gas is used instead the empty bottle at family, sell thereby finish liquid gas.Building large-scale liquefied gas station like this needs substantial contribution and large-area place, and considers that for secure context these liquefied gas stations are less, and all are built in outskirts of a town, and are far away apart from the end user, and inflation is inconvenient, makes troubles to people's life.This situation brings very big difficulty also for the popularization of dual-fuel automobile.
The model utility content
The small liquid petroleum gas charging device that the utility model purpose is to provide a kind of to be convenient in cities and towns, lpg filling is carried out in the rural area.
For reaching above-mentioned purpose, the utility model adopts following technological scheme: the liquefied petroleum gas (LPG) charging device, comprise two groups of cylinder for liquefied gas, the gas phase mouth of two groups of steel cylinders is connected in parallel in respectively on the gas phase pipe of two one end sealings, the liquid phase mouth of two groups of steel cylinders is connected in parallel on the liquid-phase tube of one one end sealing, article two, the gas phase pipe the other end connects with compressor by four-way valve, liquid-phase tube the other end connecting band valve fill pipe.
Every group of steel cylinder comprises four steel cylinders.
On the gas phase pipe pressure gauge is installed, safety valve is installed on the liquid-phase tube, steel cylinder gas phase mouth, liquid phase mouth and gas phase pipe, liquid-phase tube are equipped with valve on connecting tube.
When the utility model is started working,, just B group steel cylinder is boosted with the gas phase in the A group steel cylinder as filling with the liquefied petroleum gas (LPG) liquid phase in the B group steel cylinder.Its working procedure is: close the liquid phase valve of A group steel cylinder, open gas valve, open the gas valve and the liquid phase valve of B group steel cylinder simultaneously, start compressor, enter B group steel cylinder after at this moment can extracting the liquid gas gas phase compression in the A group steel cylinder.At this moment, the pressure in the A group steel cylinder reduces, when being lower than the saturation vapor pressure of liquid gas, liquid phase in the A group steel cylinder begins to change into gas phase, gas pressure in the B group steel cylinder raises simultaneously, and when surpassing the saturation vapor pressure of liquid gas, liquid gas becomes liquid phase by gas phase.At this moment can by link to each other with liquid-phase tube fill the pipe or fill rifle small steel cylinder carried out lpg filling.Close compressor when the pressure reduction of two groups of steel cylinders is 0.5MPa, along with the minimizing of liquid phase in the B group steel cylinder, pressure reduces, and when pressure reduction was reduced to 0.2MPa, in order to increase lpg filling speed, starting compressor was that B group steel cylinder boosts.Liquefied petroleum gas (LPG) liquid phase in the B group steel cylinder fills and finishes, and B group steel cylinder is replaced by the real bottle that is full of liquid gas.Change the position of four-way valve simultaneously, close the liquid phase valve of B group steel cylinder, open the liquid phase valve of A group steel cylinder, start compressor, the gas phase that can extract in the B group steel cylinder is boosted to A group steel cylinder, with the liquid phase in the A group steel cylinder small steel cylinder is filled.Can guarantee that so the liquid gas gas phase that compressor extracts has higher lower carbon number hydrocarbons content, can improve A group steel cylinder pressure, improve the speed that fills, reduce the compressor operating time.
The utility model utilizes two groups of steel cylinders, two vapor lines, liquidus curve, four-way valve and a compressor to connect, and can realize that device structure is simple, invests little to the filling of end user's little cylinder for liquefied gas; Be easy to produce, be convenient in cities and towns, rural multiple spot arranges, is convenient to the lives of the people; Both can be used for the lives of the people and filled, also can be used for the dual-fuel automobile aerating with cylinder for liquefied gas.The utility model cooperates with metering equipment can realize quantitative aerating.
