Description

Technical Field

[0001] The utility model relates to the technical field of heat supply regulation, in particular to a regulation mechanism of a heat supply device. Background Art

[0002] A regulating valve, also known as a control valve, is a final control element in industrial automation process control that uses power to change process parameters such as flow, pressure, temperature, and liquid level by receiving control signals from a regulating control unit. It generally consists of an actuator and a valve. Regulating valves can be categorized by stroke characteristics as linear or angular. Based on the power used by their actuators, they can be divided into pneumatic, electric, and hydraulic types. Their functions and characteristics are categorized into linear, equal percentage, and parabolic characteristics. Regulating valves are suitable for use with media such as air, water, steam, various corrosive media, mud, and oil.

[0003] For example, the Chinese patent with publication number CN211289216U proposes an insulation device for a regulating valve actuator for a heating system. The assembly includes a front insulation shell and a rear insulation shell. The lower ends of the front insulation shell and the rear insulation shell are rotatably connected by a hinge. When in use, the front insulation shell and the rear insulation shell are placed on the front and rear sides of the regulating valve actuator, the upper ends of the front insulation shell and the rear insulation shell are closed, and locked with a connecting buckle. At this time, a closed cavity is formed between the front insulation shell and the rear insulation shell and the regulating valve actuator, and a one-way air outlet pipe is used to connect the front insulation shell and the rear insulation shell. The air inside the cavity is extracted and observed through a pressure gauge until the cavity is in a vacuum state, thereby performing vacuum insulation on the regulating valve actuator. Compared with the existing insulation device, the new insulation device for the regulating valve actuator of the heating system has good insulation effect and is easy to install. It reduces the heat loss of the heat source when passing through the regulating valve. However, in the actual application of this solution, if the driving mechanism of the regulating valve is accidentally damaged or cannot function normally, the regulating valve will be unable to adjust the heating. In order to solve the above problem, we have proposed a regulating mechanism for the heating device. Utility Model Content
