HEATING FLOW CONTROL SYSTEM

摘要

The present invention relates to a household heating flow control system by a complex differential pressure flow rate control valve. Specifically, the household heating flow control system is to evenly control a heating flow rate of a household heating unit using a pressure control consistent flow rate control unit and maintain a heating flow rate of each room heating unit to be consistent in accordance with selective heating of the room heating unit of the household heating unit. According to the present invention, the household heating flow control system comprises: a differential pressure flow rate control unit (10) having the complex differential pressure flow rate control valve (1) controlling a flow rate of the each heating unit in order for the flow rate of the each heating unit to evenly flow in a supply pipe (110) of a heating flow rate control unit, wherein the differential pressure flow rate control unit (10) controls the flow rate discharged through a water collection pipe (130) in proportion to pressure difference of the water collection pipe (130) and a supply pipe (110) using the complex differential pressure flow rate control valve (1); and a strainer (30) controlling and discharging the flow rate discharged through the water collection pipe (130) to correspond to a setting flow rate in accordance with the household heating unit and removing foreign substances of a heating fluid and the pressure control consistent flow rate control unit controlling a water flow cross-section area of the heating fluid in the water collection pipe, wherein the strainer (30) stabilizes the flow of the fluid. The household heating flow control system prevents noise due to concentration of the flow rate by preventing the concentration of the flow rate and consistently maintains the heating flow rate of the each room heating unit used in accordance with change of the household heating flow rate in accordance with the selective heating of the room heating unit of the household heating unit. The household heating flow control system can evenly control the heating flow rate of the household heating unit by the pressure control consistent flow rate control unit.
