When a user indoor temperature reaches the preset value, the indoor thermostatic valve semi-automatic down, user backwater pressure relief, differential pressure increases, differential pressure valve will be appropriate office thermostatic valve, semi-automatic down fixed users differential pressure valve port to eternity. Then inverter based on user perceived needs, semi-automatic adjusting variable frequency pump operation, thus reach energy-saving variable flow operation. Depends on the change of heat supply network flow in the user's request, with hot hot objects and the change of adjusting control is given priority to with the user, the user needs a number of calories, hot objects have to supply a number of calories. Circulating water pumps, in contrast, on the basis of outdoor air temperature reduction, demand cycle water, user valve opening change, the user differential pressure for self-reliance type differential pressure stem valve stem, using the flow rate increase will not come up. Q: self-reliance type differential pressure stem valve suitable for occasions of answer: self-reliance type differential pressure valve stem uncomfortable or use with hot objects to active, variable flow control system when the system is implemented by hot objects to active flow control ( Number of frequency conversion, loss circulation pump, in pulmonary circulation pump, etc. ) And decrease the system flow, pipe network pressure will decrease, because the pressure decreases, the proximal users semi-automatic differential pressure valve valve core will be up, keeping the original differential pressure is fixed, eternal flow changes just remote user Marine valve, make the remote user traffic seriously insufficient. Pressure valve stem adapt to user to active variable flow operation of the network. The user as active variable flow form of variable flow operation is the trend from now on, is also the most energy-efficient. Near end user and the remote user can not change as traffic and geometric changes, can not maintain hydrodynamic equilibrium condition, the heat-supply revealed dynamic hydrodynamic disorders. So self-reliance type differential pressure valve stem not comfortable using active variable flow control system for hot objects. To the user to active variable flow operation has a premise, the user must install thermostatic valve automatic control device, such as thermal power self-reliance type differential pressure stem valve door entrance installed capacity successful implementation. 。 Indoor thermostatic valve installation, thermal power door entrance to install self-reliance type differential pressure stem valves, heat supply network circulation pump sees fit and use frequency conversion stem.
