Description
Technical field
The utility model relates to a kind of valve, in particular to a kind of IC card flow control low-power consumption ball valve.
Background technique
As what China's natural gas used popularizes, coal changes vigorously supporting for gas policy, and gas industry will be public utilities
Middle entirety speedup is most fast, the strongest subdivision field of attribute of growing up.According to China " planning of energy development 13 " and " natural gas hair
Open up 13 planning " etc. guide, it is desirable that the year two thousand twenty Natural Gas Consumption Using accounts for non-renewable energy ratio and is promoted to from 6.3% in 2016
6—10%.It is natural to the year two thousand twenty China if consuming planning guidance by China's natural gas by 2016 in terms of 206,500,000,000 cubes of gas consumption
The consumption figure of gas will can then calculate 2016 up to 360,000,000,000 cubes --- and between the year two thousand twenty, the consumption figure year of national natural gas, which increases, to be reached
To 15%.
Gas discharge pre-payment automatically controls that the product market demand is strong, and IC card flow control valve is and gas flowmeter
Matching used control component, the two are combined into intellective IC card gas Flowrate Control System, to realize to natural gas motorcar
