Use, the pressure in storage tank 2 can reduce with the reduction of liquid, when pressure is less than setting value, it is impossible to meet that gas starts
Requirement of the machine to gas fuel pressure, and the liquid phase medium in the control storage tank 2 for passing through pressure charging valve can be through the first pressure piping
51 inflow heat-exchanger rigs 301 are gasified, and afterwards, the gas medium after gasification flows into the gas phase of storage tank 2 through the second pressure piping
Space, so as to realize the supercharging to storage tank 2, when reaching supercharging setting value, pressure charging valve is closed automatically.
A heat-exchanger rig 301 is only set in each gas supply pipe system, it can be not only used for the heat exchange to outside supply
Device, it can also be used to the supercharging of the pressure charging system 5 so that heat-exchanger rig 301 is combined into one with dual-use function, saves ship
Upper limited space.
Wherein, be only arranged in the gas supply pipe system of left end preferential is included with gas system 6：Gas piping is (in figure not
Show) and the valve (not shown) that is arranged on gas piping；One end of gas piping connects with the gas-phase space of storage tank 2
Logical, the other end to gas engine to supply.When gaseous pressure is higher in storage tank 2 and reaches setting safety value, whole system
Valve can be preferentially opened, the gas phase media allowed in storage tank 2 supplies through gas piping to gas engine, so that the gas in storage tank 2
Phase medium is preferentially used, and to avoid the emptying of the hypertonia of storage tank 2 and fuel from losing, reduces the service wear of LNG fuel
Rate.
The charging system being only arranged in the gas supply pipe system of right-hand member includes：Liquid phase pipeline 71, gas phase pipeline 72, filtering
Device 701 and overflow mechanism 702.
Liquid phase pipeline 71 and gas phase pipeline 72 respectively with storage tank 2 and the filling equipment (such as tank car or gas station) of outside
The gentle phase pipeline connection of liquid phase pipeline, filter 701 are arranged on liquid phase pipeline 71.Specifically, liquid pump or supercharging are passed through
The LNG fuel of outside filling equipment is delivered into filter 701 through liquid phase pipeline 71 to be filtered, and by after filtering
LNG fuel carries out topping up to storage tank 2；During topping up is carried out to storage tank 2, when the pressure in storage tank 2 reaches an early warning value,
Gas phase media in storage tank 2 can be delivered to the filling equipment of outside through gas phase pipeline 72, release pressure, and can reduce and put
Sky loss.After the LNG fuel in storage tank 2 reaches preset value, overflow mechanism 702 can send alarm and automatically cut off to storage tank
2 topping up, prevent from overcharging.
In the present embodiment, positioned at the left and right ends of storage tank 2 gas supply pipe system it is slightly different in structure so that both ends
Also difference, the gas supply pipe system main system of the present embodiment right-hand member, left end have been pair to function possessed by gas supply pipe system
System, on the premise of double supply functions are ensured, system cost is reduced as far as possible.However, in actual use, positioned at left and right ends
Gas supply pipe system structure can with identical, can also by increase and decrease make storage tank both ends gas supply pipe system have it is required
Function.
Although describing the present invention with reference to above exemplary embodiment, it is to be understood that, term used be explanation and
Exemplary and nonrestrictive term.Due to the present invention can be embodied in a variety of forms without departing from invention spirit or
Essence, it should therefore be appreciated that above-mentioned embodiment is not limited to any foregoing details, and should be limited in appended claims
