Dali natural gas voltage regulator is full and complete
Work monitoring and voltage regulation system
Monitoring for the spare time we usually say, that is, in the work of the Run Feng gas pressure regulating valve failure, the downstream pressure to monitor the setting point of the pressure control valve of the Run Feng gas, the monitoring and control of the moistening gas pressure valve quickly switch to work state, immediately replace the main pressure regulator to adjust pressure, ensure the continuity and stability of gas supply]. It is divided into parallel monitoring and series monitoring according to monitoring mode.
2.2.1 parallel monitoring mode
In parallel, two models of the same type are used in parallel. As shown in Figure 5, a main road to moisten the gas pressure regulating valve, and one of the monitoring and control valve for the spare road.
Figure 5 voltage regulation system for parallel monitoring
In Figure 5, the above line is on the road, the following line is the backup road. Under normal circumstances, the reason for the low pressure setting due to the pressure relief valve of the standby line is the reason for the low pressure setting (P
