Abstract
The utility model discloses a gas filling device, which is additionally provided with a gas recycling pipeline in an existing scheme. A recycling valve is mounted on the recycling pipeline. The gas filling device can effectively recycle residual gas after filling via the gas recycling pipeline after completing gas filling, reduces waste of gas, protects environment, and also improves benefits.
Description
Technical field
The utility model relates to a kind of gas filling device, is specifically related to a kind of gas filling device that has gas recovery system.
Background technique
Existing carbon dioxide charging system, critical piece is liquid gas storage tank, liquid pump and filling equipment.Its cardinal principle is to utilize the liquid pump pressurization, by pipeline the gas branch is filled in each steel cylinder again, after filling at every turn, owing on the liquid pump check device is arranged, behind the liquid pump and the residual gas in the pipeline between gas filling device part can not return the liquid gas storage tank, this part liquid gas is all carried out emptying and is handled, so just cause the significant wastage of gas, if not carrying out emptying handles, liquid gas will be gasified after temperature raise, volume sharply expands, and this moment, manifold pressure can sharply raise, and caused security incident.
The model utility content
The utility model fills the deficiency that liquefied gas remaining behind the gas can not be recovered in order to overcome in the prior art, a kind of gas filling device is provided.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of gas filling device, comprise liquid gas storage tank, liquid pump, filling equipment, also be provided with the gas recovery pipe road, gas recovery pipe Lu Yiduan is connected on the pipeline between liquid pump and the filling equipment, the other end is connected on the liquid gas storage tank, and the gas recovery pipe road is provided with the recovery valve.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is simple in structure, behind the gas filling, has effectively reclaimed remaining gas, thereby reduces gaseous emission, has protected environment; Reduce the waste after filling, increase the benefit; Prevent the air accumulation of emptying, caused security incident.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representations.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
Embodiment 1
As shown in Figure 1, a kind of gas filling device, comprise liquid gas storage tank 1, liquid pump 3, filling equipment 5, also be provided with gas recovery pipe road 7, gas recovery pipe road 7 one ends are connected on the pipeline between liquid pump and the filling equipment, the other end is connected on the liquid gas storage tank 1, and gas recovery pipe road 7 is provided with reclaims valve 6.
Splendid attire is liquefied carbon dioxide gas in the liquid gas storage tank 1, and carbon dioxide is through behind the liquid pump 3, and in filling equipment 5 was packed dioxy flower carbon steel bottle into, reclaimed valve 6 and close by this moment by pipeline 2 for carbon dioxide.Fill finish after, valve 4 is closed, remainder carbon dioxide in the pipeline 2 is opened and is reclaimed valve 6, and residual carbon dioxide is poured in the liquid gas storage tank 1.
As shown in Figure 2, a kind of gas filling device, comprise liquid gas storage tank 1, liquid pump 3, filling equipment 5, also be provided with gas recovery pipe road 7, gas recovery pipe road 7 one ends are connected on the pipeline between liquid pump and the filling equipment, the other end is connected on the liquid gas storage tank 1, and gas recovery pipe road 7 is provided with reclaims valve 6.
Splendid attire is liquid oxygen in the liquid gas storage tank 1, and oxygen is through behind the liquid pump 3, and in filling equipment 5 was packed oxygen bottle into, reclaimed valve 6 and close by this moment by pipeline 2 for oxygen.Fill finish after, valve 4 is closed, remainder oxygen in the pipeline 2 is opened and is reclaimed valve 6, and remaining oxygen is poured in the liquid gas storage tank 1.
