| 摘要 |
The invention relates to a pre-adjustable flow-rate controller for heating systems, comprising a housing, which has a heating medium feed connection, a heating medium drain connection, and a pre-adjustment connection, and comprising a rate regulating insert, which changes the flow cross-section for the heating medium depending on the pressure in the rate regulating insert, wherein the rate regulating insert has a cone on the drain-connection side, which cone interacts with a hollow cone. The cone and the hollow cone together form an annular space for the draining heating medium. The hollow cone is connected to the control sleeve and the cone penetrates the opening of a pot bottom. |
