Description

Technical Field

[0001] This utility model relates to an integrated intelligent measurement and control device for a heat inlet, belonging to the field of heating application technology. Background Technology

[0002] The heat inlet is a crucial component of the heating system, located in a dedicated room in the basement. Traditional heat inlet devices typically consist of on / off valves, filters, balancing valves (static and dynamic), control valves, heat meters, two thermometers, and three to four pressure gauges, and are operated manually. With the development of intelligent heating systems, parameters such as temperature, pressure, flow rate, and heat output at the heat inlet need to be collected, requiring the installation of two temperature transmitters and three pressure transmitters. Remote control capabilities are also required, and manual control valves are now commonly replaced by intelligent control valves for remote regulation.

[0003] In recent years, our company has launched an intelligent heat inlet device and obtained a utility model authorization. This device adds intelligent data acquisition and control components to the traditional heat inlet device. However, in actual use (installation), it suffers from problems such as excessive device length, increased construction difficulty, technical complexity, and increased difficulty in cross-construction. Its high cost has prevented widespread acceptance by users. Meanwhile, some balancing valve manufacturers have launched integrated heat inlet devices, which have gained recognition primarily due to their integrated factory production and balancing valve technology. However, these devices mainly operate in a traditional manual mode and are not well-suited to the current demands of intelligent systems. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an integrated intelligent monitoring and control device for heat inlets. This device integrates a straight-pipe ultrasonic heat meter, intelligent control valve, temperature transmitter, pressure transmitter, digital display acquisition and control instrument, and pipeline into a single unit, which is then processed, manufactured, and debugged in the workshop and connected to an Internet of Things (IoT) platform. The entire unit can then be transported to the site for welding to complete the process. The specific technical solution is as follows:

[0005] This utility model proposes an integrated intelligent measurement and control device for a thermal inlet. The integrated intelligent measurement and control device is an integrated type, including a first integrated unit A and a second integrated unit B. The first integrated unit A is installed on the water supply pipe, and the second integrated unit B is installed on the return water pipe.

[0006] The first integrated unit A includes a first straight pipe section, both ends of which are connected to a water supply pipe. A straight pipe type ultrasonic heat meter is installed on the first straight pipe section, and the straight pipe type ultrasonic heat meter and the straight pipe section are manufactured as one piece. A first temperature transmitter and a first pressure transmitter are also installed on the first straight pipe section. The first integrated unit A also includes a digital display acquisition and control instrument, and the straight pipe type ultrasonic heat meter, the first temperature transmitter and the first pressure transmitter are all electrically connected to the digital display acquisition and control instrument.

[0007] The second integrated unit B includes a second straight pipe, both ends of which are connected to the return water pipe. An intelligent control valve, a second temperature transmitter, and a second pressure transmitter are installed on the second straight pipe. The intelligent control valve, the second temperature transmitter, and the second pressure transmitter are all electrically connected to the digital display acquisition and control instrument.

[0008] Connect the digital display acquisition and control instrument to the Internet of Things platform.

[0009] Furthermore, a mounting base for a first temperature transmitter and a first pressure transmitter is provided on the first straight section pipe, and a mounting base for a second temperature transmitter and a second pressure transmitter is fixed on the second straight section pipe.

[0010] Furthermore, the mounting base is fixed by welding.

[0011] Furthermore, a first welded ball valve is provided between the left end of the first straight section pipe and the water supply pipe, and a second welded ball valve is provided between the right end of the first straight section pipe and the water supply pipe.

[0014] Furthermore, a third welded ball valve is provided between the left end of the second straight section pipe and the return water pipe, and a fourth welded ball valve is provided between the right end of the second straight section pipe and the return water pipe.

[0015] Compared with the prior art, this utility model has the following functions and beneficial effects:

[0016] 1. The process involves prefabrication, processing, assembly, and debugging at a processing plant, followed by integrated transportation to the site for installation. This reduces the randomness of on-site construction, significantly lowers the difficulty of on-site installation, and ensures quality.

[0017] 2. The traditional thermometers (2) and pressure gauges (3-4) were eliminated. Temperature transmitters and pressure transmitters were installed to collect data, which was then displayed on-site through a digital display controller. This enabled data acquisition, ensured on-site data viewing, reduced costs, and shortened pipe sections.

[0018] 3. A straight-pipe ultrasonic heat meter is adopted, with temperature transmitters, pressure transmitters, and other mounting bases welded onto the straight pipe section. This eliminates the need for flanges, enabling a flangeless connection for the integrated control cabinet. The straight pipe section effectively ensures the accuracy of metering and reduces the difficulty of on-site construction. Furthermore, a protective coating is applied to the entire device, and it undergoes factory testing, greatly guaranteeing the quality of the device.

[0019] 4. The integrated intelligent monitoring and control device for the heat inlet integrates the monitoring and control equipment together, and completely entrusts the procurement and installation of the switching valves and filters to the heating installation team. This greatly reduces the difficulty and workload of coordinating the three disciplines of heating, electrical and intelligent systems, which not only reduces the probability of errors and ensures the quality of the device, but also saves labor costs.

[0020] 5. This device includes a digital display acquisition and control instrument, which can display parameters such as temperature, pressure, flow rate, and heat on site. It can also control intelligent valves on site and remotely to realize multiple control strategies such as return water temperature, pressure difference, flow rate, and heat, and achieve balanced and energy-saving operation of the two networks.

[0021] 6. The digital display acquisition and control instrument of this device can automatically upload data to the Internet of Things (IoT) platform after leaving the factory (already debugged). Users can manage and control the device through the IoT platform and connect it to their own platform, which greatly reduces the management difficulty for heating companies.

[0022] 7. This device controls pressure, temperature, and flow rate acquisition instruments and electric regulating valves, which are stable in operation, resistant to interference, have good real-time data upload, high response speed, and high control accuracy, and can monitor, acquire, and control in real time, bringing users a better experience.
