Example Embodiment

[0038] The pipeline system of the hydraulic CNG refilling sub-station provided in the first embodiment includes a gas storage mechanism, a refilling machine 300, a pressure boosting mechanism 400 and a distribution valve 500.

[0039] The gas storage mechanism includes a plurality of gas storage cylinders. According to different connection relationships, the plurality of gas storage bottles form two groups, which are called the first gas storage cylinder group 100 and the second gas storage cylinder group 200. The first gas cylinder group 100 includes a plurality of first gas cylinders 110, and the plurality of first gas cylinders are respectively marked as S1, S2...Sm. Similarly, the second gas cylinder group 200 includes a plurality of second gas cylinders 210, and the plurality of second gas cylinders are respectively marked with T1, T2...Tm. Among them, m is an integer.

[0040] On the one hand, a plurality of output control valves corresponding to the gas cylinders are provid...

Abstract

The invention discloses a pipeline system and a control system of a gas filling substation and the gas filling substation comprising the same and also discloses a control method of the gas filling substation. The disclosed pipeline system of the gas filling substation comprises a pressurization mechanism and a gas dispenser and also comprises a first gasbomb set and a second gasbomb set, wherein the first gasbomb set comprises a plurality of first gasbombs, and the second gasbomb set comprises a pluraity of second gasbombs; the output ends of the first gasbombs are communicated with the first input port of a distributing valve by a first output control valve; the output ends of the second gasbombs are communicated with the second input port of the distributing valve by a second output control valve; and the pressurization ends of the first gasbombs and the pressurization ends of the second gasbombs are respectively communicated with the pressurization port the pressurization mechanism by a first pressurization control valve and a second pressurization control valve. The technical scheme can improve the gap pickup rate of the system while improving the gas supply capacity of the hydraulic CNG (Compressed Natural Gas) gas filling substation.

Description

technical field [0001] The present invention relates to a hydraulic CNG (Compressed Natural Gas, compressed natural gas) gas filling technology, in particular to a pipeline system, a control system of a hydraulic CNG gas filling substation and a hydraulic system including the pipeline system and the control system. A control method for a type CNG sub-station and a hydraulic CNG sub-station. Background technique [0002] At present, natural gas has been widely used in many aspects of society and life. Among them, the use of natural gas as fuel to drive the operation of other equipment has become an important aspect of natural gas utilization. In order to facilitate transportation and loading, compressed natural gas (CNG) is formed by pressurizing natural gas, which has become one of the important ways of natural gas utilization. [0003] In order to expand the scope of use of CNG, currently it is usually adopted to set up a CNG refueling sub-station at a predetermined posit...
