A system of controlling differential pressure in a hot water distributor is provided to reduce a differential pressure between a water supplying header and a water returning header without losing heat by transferring pressure, which is introduced into a static pressure signal tube of the water supplying head, into a differential pressure control valve, through a pressure injection plug. A system of controlling differential pressure in a hot water distributor for heating comprises a water supplying header(2), a water returning header(4), a water supply line(6) connected between the water supplying header and the water returning header and a differential pressure control valve(50). The differential pressure control valve is connected between the water returning header and the water returning tube. A static pressure signal pipe(1a) is formed on the water supplying header. The static pressure signal pipe is connected to a pressure injection plug installed on the differential pressure control valve. |
