Abstract
The utility model provides a compressed natural gas filling substation, which comprises a liquid storage tank. The liquid storage tank is provided with a delivery pipe and a return pipe; the delivery pipe is provided with a high-pressure pump; the crossed position of the delivery pipe and the return pipe is provided with a pressure control valve; the pressure control valve is mutually connected with a plurality of gas storage steel bottles after being controlled by a programmable logic controller (PLC) control system; the inlet position of each gas storage steel bottle is provided with a valve; and outlets of the gas storage steel bottles are mutually connected with a gas filling machine after being joined. The compressed natural gas filling substation provided by the utility model has the beneficial effects that the degree of automation of gas filling is high; the gas filling efficiency is improved; and the gas filling pressure can be controlled.
Description
Technical field
The utility model belongs to the compressed natural gas transportation semitrailer field, especially relates to a kind of compressed natural gas filling substation.
Background technique
Natural gas automobile secondary gas filling station is that the Medium Oil with special nature is filled with in the bottle formula pressurized container of compressed natural gas long-tube trailer with high pressure (being not more than 24MPa), compressed natural gas in the bottle formula pressurized container is released, realized giving the cluster tool that rock gas is the refueling of fuel by the filling machine in standing.The aerator of present employed compressed natural gas transportation semitrailer fails to realize automation, and aerating needs the human assistance aerating, and aerating efficient is lower, wastes time and energy, and does not satisfy the needs of modern society.
Summary of the invention
Problem to be solved in the utility model provides a kind of compressed natural gas filling substation, has especially that the aerating automaticity is high, aerating efficient improves, and can control the advantage such as aerating air pressure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of compressed natural gas filling substation, comprise wet tank, be provided with delivery pipe and reflow pipe at described wet tank, be provided with a high-pressure service pump at described delivery pipe, infall at described delivery pipe and reflow pipe is provided with pressure controlled valve, pressure controlled valve is connected with several gas storage cylinders after the control of PLC control system, entrance location place at each gas storage cylinder is provided with respectively a valve, is connected with filling machine after described several gas storage cylinder outlets converge.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, the aerating automaticity is high, aerating efficient improves so that the utlity model has, and can control the advantage such as aerating air pressure.

Embodiment
As shown in Figure 1, the utility model comprises wet tank 1, be provided with delivery pipe 2 and reflow pipe 3 at described wet tank 1, be provided with a high-pressure service pump 4 at described delivery pipe 2, infall at described delivery pipe 2 and reflow pipe 3 is provided with pressure controlled valve 6, pressure controlled valve 6 is connected with several gas storage cylinders 8 after 5 controls of PLC control system, be provided with respectively a valve 7 at the entrance location place of each gas storage cylinder 8, after converging, described several gas storage cylinder 8 outlets are connected with filling machine 9, in the present embodiment, have 3 gas storage cylinders 8.
The working procedure of this example: when beginning starting device or PLC control system 5 monitor hydraulic system pressure when low, high-pressure service pump 4 is started working, in gas storage cylinder 8, be filled with high-pressure liquid medium, the liquid outlet pressure control range that pressure controlled valve 6 is set is 20-24MPa, there is PLC control system 5 by pressure transducer and pneumatic actuator pressure controlled valve 6 to be controlled, when hydraulic system pressure reaches upper limit 24MPa, pressure controlled valve 6 stops to gas storage cylinder 8 feed flows, and by reflow pipe 3 highly pressurised liquid is back in the wet tank 1, high-pressure service pump 4 is through after a while time-delay, if the pressure of gas storage cylinder 8 does not still fall, then high-pressure service pump 4 quits work, when the Pressure Drop of gas storage cylinder 8 during to lower limit 20MPa, high-pressure service pump 4 restarts work.Valve 7 is used for the switch of control gas storage cylinder 8, and when gas storage cylinder arranged side by side 8 during greater than 3, the pipeline after converging should be connected with the high pressure admission mouth of filling machine 9; When only having 1-2 valve 7 to open, should with filling machine 9 low, in compress into gas port and connect, so valve 7 has played the effect of control air pressure intensity.
Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
