Abstract
The utility model discloses a pressure volume automatic gas distribution system, which comprises a feed gas system used for storing feed gas, a constant temperature system used to provide heat for enabling the feed gas to transfer from the liquid state into the gaseous state, an allocation system, a gas storage system and a control system. Due to the adoption of the constant temperature system, the temperature of the feed gas is ensured to be constant, so that the gas distribution error due to the temperature influence is minimized. Since the low-pressure gas distribution is performed through the allocation system during the gas distribution process, the gas distribution error due to the gas compressibility during the high-pressure gas distribution process can be eliminated. The gas storage system is used for uniformly mixing and storing the gas entering the system from the upstream thereof. The control system controls and monitors the feed gas system, the constant temperature system, the allocation system and the gas storage system and then responds timely. Due to the adoption of the pressure volume automatic gas distribution system, the contradiction between the gas distribution precision and factors, such as the pressure fluctuation, the ambient temperature, the system temperature and the uneven gas mixing, is economically and maximally solved. The pressure volume automatic gas distribution system is simple in structure and reliable and can meet the requirement on gas supply in various occasions.
