Filling liquid valve port.Liquid-feeding pump 615 and the first liquid phase control valve 618 are closed, completion fills external reservoir.If failing to close in time
Liquid-feeding pump 615 and the first liquid phase control valve 618, the liquefied gas in the first liquid phase pipeline 61 is assembled, and then leads to first
Pressure rise in liquid phase pipeline 61, it is other when the pressure in the first liquid phase pipeline 61 reaches the setup pressure value of by-passing valve 642
Port valve 642 is opened, so that the liquefied gas in the first liquid phase pipeline 61 flows back into tank by bypass line 64 and gas phase pipeline 63
In body 2, and then reduce the pressure in the first liquid phase pipeline 61.If by-passing valve 642 breaks down at this time, the first liquid phase pipeline 61
In liquefied gas can be discharged by the first bleeder valve 616 and the first diffusion valve 619, the first bleeder valve 616 and the first diffusion valve
619 play the role of multiple security.
When tank car needs to fill liquefied gas to external fueling station, gas phase handling connector 635 is connected to external fueling station, and
Liquid phase loads and unloads fittings in external fueling station.If the pressure in tank body 2 is greater than the pressure of the gas-phase space of external fueling station,
Close the gentle phase control valve 633 of gas phase quick action emergency valve 631.If the pressure in tank body 2 is less than the gas-phase space of external fueling station
Pressure, then gas phase control valve 633 and gas phase quick action emergency valve 631 are opened, so that the gaseous oil gas in external fueling station
It under differential pressure action, is flowed in tank body 2 by gas phase pipeline 63, so that the gas of the pressure in tank body 2 and external fueling station
The pressure of phase space balances each other, and closes gas phase control valve 633, fills liquefied gas to external fueling station conducive to tank body 2.Open the
Two liquid phase control valves 622 enable the liquefied gas in tank car to be transferred in external fueling station by second liquid phase pipeline 62.
When tank car receives the liquefied gas that external fueling station transmission comes, gas phase handling connector 635 is connected to external fueling station,
And liquid phase handling fittings are in external fueling station.If the pressure in tank body 2 is less than the pressure of the gas-phase space of external fueling station,
Then close the gentle phase control valve 633 of gas phase quick action emergency valve 631.If the gas phase that the pressure in tank body 2 is greater than external fueling station is empty
Between pressure, then gas phase control valve 633 is opened, so that the gaseous oil gas in tank body 2 passes through gas phase pipe under differential pressure action
Road 63 flows in external fueling station, so that the pressure in tank body 2 and the pressure of the gas-phase space of external fueling station balance each other,
Gas phase control valve 633 is closed, fills liquefied gas to tank body 2 conducive to external fueling station.Second liquid phase control valve 622 is opened, is made
The liquefied gas obtained in external fueling station can be transferred in tank car by second liquid phase pipeline 62.
In handling 6 course of work of liquid device, if burst fortuitous event occurs, staff can by operating assembly 66 or
Long-range control assembly closes liquid phase quick action emergency valve 614 and gas phase quick action emergency valve 631, to protect tank car.
The present invention has at least the following advantages:
Firstly, offering gas phase mouth 22 and liquid phase mouth 21 on tank body 2；The input end and second liquid phase of first liquid phase pipeline 61
One end of pipeline 62 is connected to same liquid phase mouth 21 jointly, and the outlet end of the first liquid phase pipeline 61 is used to be connected to external reservoir, and
The other end of second liquid phase pipeline 62 is for being connected to external fueling station；When second liquid phase pipeline 62 is connected to external fueling station,
First liquid phase control valve 618 is closed；When the first liquid phase pipeline 61 is connected to external reservoir, second liquid phase control valve 622 is closed,
The first liquid phase pipeline 61 and second liquid phase pipeline 62 are independent of each other use as a result,.First liquid phase pipeline 61 and second liquid phase pipeline
62 share a liquid phase mouth 21, so that 2 upper opening quantity of tank body is reduced, and then reduce the risk factor that tank body 2 is revealed.
Also, tank car can give external reservoir gas supply whenever and wherever possible, avoid user external reservoir is transported to fueling station and fill
Gas saves the time of user, eliminates user and voluntarily carries the security risk occurred when external reservoir, improves and fill efficiency,
Risk in transit is reduced, optimization fills the frequency, reduces risk in transit, improves safety；And it is not necessarily to user's connecting line, most
Amateur operation is avoided in big degree.
