摘要： functions in the three-way valve 103, it connects the inlet 8 and the output 10, and furthermore the water is routed to the pump 105 and back to the primary heat exchanger 108.
Industrial Applicability
The invention is usable in heating devices, especially in hot water boilers, to prevent damage to the heating device caused either by high pressure differences in the system of radiators and their thermostats or in an emergency shutdown of the system. The desired differential pressure of the heating system is adjusted on the spring of an electronically controlled bypass valve integrated into the three-way valve and the valve thus adjusted is engaged in a system with either one or two heating circuits. The differential pressure can be electronically adjusted with the same electric drive that electronically controls the three-way valve. While the device is operating, the desired differential pressure for the heating system can be electronically adjusted by changing the preload of the spring in the bypass valve integrated into the three-way value, without needing to exchange springs physically.
