The invention relates to a regulating device (1) for the improved self-regulating regulation of a flow regulating valve (2). The adjustment device (1) is arranged to raise the opening position of the flow control valve (2) along the adjustment stroke to an opening position with a larger flow cross section when various conditions occur, after which the opening position of the flow control valve (2) is readjusted on the basis of the adjustment difference ([Delta] Tcontrol difference). These conditions relate to the region of the adjusted opening position of the flow control valve (2), the temperature difference ([Delta] Tist) and the expiration of the repetition interval. 本发明提出了一种用于对流量调节阀(2)进行改进的自调节式调节的调节装置(1)。调节装置(1)设置成在发生各种条件时将流量调节阀(2)的开度位置沿调节行程提高到具有较大流量横截面的开度位置，之后基于调节差(ΔTcontrol difference)重新调节流量调节阀(2)的开度位置。这些条件涉及流量调节阀(2)的已调节的开度位置的区域、温度差(ΔTist)和重复间隔的到期。
