Description

Technical Field

[0001] The utility model provides a control device for constant flow regulation in a heat exchange station, belonging to the technical field of heat exchange stations. Background Art

[0002] The heat exchange station is a key facility in the centralized heating system. It plays the role of heat energy conversion and distribution. The heat exchange station transfers the heat from the heat source such as high-temperature hot water or steam generated by thermal power plants and regional boiler rooms to the secondary circulating water system through high-efficiency heat exchangers, instead of directly mixing the heat source water with the user system, thereby realizing the safe and efficient utilization and distribution of thermal energy. In this process, the high-temperature heat medium circulates on one side of the heat exchanger and transfers the heat to the low-temperature circulating water on the other side. The heated circulating water is then transported to various buildings through the pipeline network to provide users with heating or domestic hot water, while the heat source water flows back to the heat source for reheating, forming a closed-loop circulation. The automatic control system of the heat exchange station can accurately adjust the water supply temperature and flow rate, ensure the quality of heating, and optimize energy utilization efficiency. It is an important part of the modern urban centralized heating system.

[0019] according to Figure 1 As shown: the top of the console 5 is located at the waist of the worker; this makes it convenient for the worker to operate the remote control module 1, the main control module 2, and the control panel 3. The main control module 2 can conveniently control the device. At the same time, with the help of the remote control module 1, the working status of the device can be monitored and sent to the external mobile terminal, which can assist the operator to control the device. The control panel 3 can control the electrical components of the device, thereby facilitating the control of the device.

[0020] according to Figure 1 , 2 As shown: the plate heat exchanger 6 includes a plurality of heat exchange plates 602, frames 603 arranged at both ends of the plurality of heat exchange plates 602, bolts 604 for clamping the two frames 603 to make the plurality of heat exchange plates 602 fit tightly, water holes are respectively arranged at the four corners of the plurality of heat exchange plates 602, the two frames 603 are provided with water holes corresponding to the heat exchange plates 602, sealing strips are arranged at both ends of the two water holes on one side of the heat exchange plate 602 and at the outer edge of the heat exchange plate 602, a frame 603 is located outside the water hole and is provided with a heat exchange pipe 1 6011, and the other frame 603 is located outside the water hole and is provided with heat exchange pipes 2 6012 on both sides thereof that are connected to the water holes on the same side; the plate heat exchanger 6 designed in this way has high heat exchange efficiency;

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
