Embodiment Construction

[0009] In the above drawings, the gas filling machine for automatically sorting and taking gas is formed by connecting the gas taking control system, the gas flow meter 7 and the gas filling gun 8 . The air intake control system is composed of three intake pipelines 1 equipped with pressure transmitters 2 and solenoid valves 3 in sequence, and an electronic control panel 4 with a display screen 5 . The electronic control panel 4 is equipped with a microcomputer information processing system, a management system and an acousto-optic prompting system, which can automatically open each solenoid valve 3 in the order of low, medium and high pressure according to the signals of the pressure transmitter 2 on the three intake pipelines 1. Gas, pressure switching time can be adjusted, can set the pressure is too low to remind the replacement of the data of the gas cabinet, then the audible and visual reminder will be given. The medium of the gas flowmeter 7 is natural gas, the maximum ...

Abstract

The invention relates to a gas feeding device which can automatically feed gas in sequence, belonging to the compression natural gas vehicle feeding technique. It is formed by a gas feeding control system, a gas flow counter, and a gas feeding gun. Wherein, the gas feeding system comprises three air inlet tubes which are individually mounted with pressure transmitter and electromagnetic valve, and a electric control disc with the display screen to accept the pressure variable signal of each air inlet tube, and automatically switch the electromagnetic valve to attain gas according the sequence of low, middle and high; and the pressure switch time can be adjusted while it can process audio-virtual prompt on the gas bank with too low pressure. The aforementioned devices are mounted inside a frame. Compared to present products, the invention can improve the gas feeding rate, simplify the process, avoid fixing air bank and compressor, reduce investment, reduce operation cost, simplify operation and it especially apply the gas feeding stations with pry gas banks.

Description

Technical field: [0001] The invention relates to the technical field of gas filling for compressed natural gas vehicles, in particular to a gas filling machine for automatically sorting and taking gas. technical background: [0002] Existing compressed natural gas filling machines are usually used in gas filling stations with fixed low, medium and high pressure gas storages, and gas is taken from the fixed gas storages in the order of fixed low, medium and high pressure to refuel gas vehicles . However, it cannot adapt to the frequent changes in the sequence of low, medium and high pressure caused by the frequent replacement of skid-mounted gas tanks during the work of gas stations using skid-mounted gas tanks, so it cannot be used for more and more skid-mounted gas tanks in China. Station and gas filling sub-stations supplied by skid-mounted gas tanks. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the existing gas di...
