HEAT SUPPLY SYSTEM Russian patent published in 2023 - IPC F24D3/02 

FIELD: heat supply systems.

SUBSTANCE: heat supply system includes heating devices, supply and return pipelines, two single-section diaphragm pumps, one section being the working section and the second being the pumping section. Each section is divided by diaphragms into active and passive chambers; the diaphragms are connected to each other by a rigid rod, in the middle part of which, on the side of the passive working chamber, a stop is rigidly installed on the rod, supported by a spring. The active working chamber is equipped with an inlet and outlet valve connected to switching devices mechanically connected to the diaphragm. The active pump section is hydraulically connected in parallel through the discharge check valve to the heating devices and the outlet valve, and through the suction check valve in parallel with the return pipeline and the outlet of the heater. A direct-acting weather regulator is installed on the supply pipeline, hydraulically connected to a control heat exchanger installed on the return pipeline bypass line.

EFFECT: efficiency of operation of consumer heating devices due to a deeper use of the coolant potential at the pulsation frequency of a two-section diaphragm pump, regulation of the mixing coefficient depending on the established quality control schedule.
