How does a steam prepaid system implement valve control?

The steam prepayment system is a system that integrates computer technology, communication technology, and metering technology. It uses mobile data transmission networks to connect the metering monitoring substations with the heating network monitoring center to achieve data collection, processing, transmission, Monitoring and control effects. Among them, the valve and its electric actuator are part of the metering and monitoring substation and an important part of monitoring and control in the steam prepayment system.

In the Supmea Measurement and Control Steam Prepayment System, valve control is mainly reflected in two aspects. On the one hand, it is reflected in the authorized opening of the valve in the heating network monitoring center after recharging the heat user. When the user's balance is higher than the limited alarm value, the valve opens normally and the user uses gas normally; when the balance is greater than zero but lower than the alarm value, the prepayment system automatically sends a balance reminder message to the hot user manager. At this time, the valve is normal Open; when the prepaid amount in the account is consumed and the balance reaches zero, the prepayment system issues an instruction to close the valve and cut off the gas use. On the other hand, in the Hesheng Measurement and Control Steam Prepayment System, the valves use high-performance electric valves and imported actuators. The valve switch state does not change in case of unexpected power outage, preventing accidental closing of the valve from causing disputes between the two parties. In addition, the steam prepayment system can also be divided into manual on-off valves and automatic on-off valves, which can fully meet different needs under different working conditions and facilitate efficient management of the steam supplier.

The steam prepayment system fundamentally eliminates the phenomenon of hot users or units defaulting on steam payment through remote control of valves, and completes the charging concept from "use steam first, pay later" to "pay first , the transformation of "post-use steam". Hesheng Measurement and Control Steam Prepayment System has been widely used in the construction projects of many groups such as National Energy Group, Huaneng Group, Datang Group, Huadian Group, and Everbright Group. In the future, Hesheng Measurement and Control will always adhere to the development concept of "technological innovation and continuous improvement", continue to delve into the field of thermal energy measurement, and work with various enterprises to recommend industry technological progress and scientific development!
