Refering to fig. 10, the working principle of the present embodiment natural gas supply system is: on pipeline 42 after pressure maintaining valve 6, slow
The gas-phase space of the connection gas cylinder 2 of pipeline 43 is drawn before rushing tank 32 to constitute primary Ioops, the gas phase day for utilizing vaporizer 31 to vaporize
Right conductance enters in gas cylinder 2 to be pressurized.Meanwhile to avoid causing surge tank 32 for unsaturated vapor, surge tank 32 for the pressurization
It is preceding to be provided with check-valves 5, prevent gas phase natural gas from being returned in the lower gas cylinder 2 of pressure by surge tank 32.When 2 pressure of gas cylinder is less than
Pressure maintaining valve 6 sets pressure, opens pressurization opening valve 8, and gas phase natural gas returns in the low gas cylinder 2 of pressure, as vehicle is (slow with gas
The gas supply of tank 32 is rushed, pressure gradually decreases) and the pressurization of gas cylinder 2 (2 pressure of gas cylinder is gradually increasing), gas cylinder 2 and 32 pressure of surge tank hair
Changing, subsequent gas phase natural gas enter the low component of pressure, alternately enter in gas cylinder 2 or surge tank 32, carry out gas cylinder 2 and increase
Pressure or vehicle gas supply.Pressure maintaining valve 6 is that rear end controls pressure regulation, i.e., when 32 pressure of surge tank sets pressure lower than pressure maintaining valve 6, gas phase day
Right gas enters surge tank 32 by pressure maintaining valve 6, and 32 pressure of surge tank is greater than pressure maintaining valve 6 and sets pressure, and pressure maintaining valve 6 is closed, gas phase
Natural gas stops entering surge tank 32, and the setting of pressure maintaining valve 6 pressure is higher, guarantees have sufficient natural gas to enter by pressure maintaining valve 6
Surge tank 32, surge tank 32 has the natural gas of enough volume storage certain pressures, and vaporizer 31 heat exchange coil 311a, 311b have
Sufficient length has enough vaporization capacities, can guarantee that the natural gas of vaporization is sufficient, can meet the pressurization of gas cylinder 2 simultaneously and vehicle supplies
Gas.
The present invention realizes the highly integrated of Vehicular liquefied natural gas supply system, and component valve pipeline is less, and system is more
Add and simplify beauty, reduce manually, air supply system cost is lower, has more the market competitiveness.And vehicle applicatory is more,
Versatility is stronger, while being also to be ready by the use of the car of fuel of liquefied natural gas.
Although describing the present invention with reference to the above exemplary embodiment, it is to be understood that, term used be explanation and
Term exemplary, and not restrictive.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 embodiment is not limited to any of the foregoing details, and should be defined by the appended claims
The whole change and modification widely explained, therefore fallen into claim or its equivalent scope in spirit and scope all should be with
Attached claim is covered.
