Description

The flow characteristic curve has a large deviation in actual use. It has a relatively large impact on the adjustment performance. The valve cannot be resolved by hydraulic imbalance (that is, there is no dynamic hydraulic balancing function), which brings inconvenience to users.

[0004] 2. The existing energy valve only has the function of monitoring temperature and cannot perform constant water temperature difference control in real time.

[0005] 3. The existing energy valve needs to detect the flow rate through other means (flow meter), and the corresponding flow meter needs to be installed when monitoring the flow, which brings inconvenience to the user.

[0006] 4.

[0020] As a further preferred embodiment of the present invention: the Internet of Things controller is provided with TCP / IP, WiFi, power line carrier, 4G / 5G, Bluetooth, WiFi, and power line carrier modules.

[0021] The beneficial effects of the present invention are embodied in:

[0022] 1. The present invention is provided with a first water temperature sensor and a second water temperature sensor on the front and rear sides of the valve body, that is, to measure the temperature difference between the water supply pipe and the return pipe of the closed-loop water circuit. The Internet of Things controller automatically adjusts according to the set water supply temperature difference, thereby reducing the water flow output, solving the working conditions of large flow and small temperature difference, and reducing the energy consumption of the water pump. The first water temperature sensor and the second water temperature sensor are used to detect the temperature of the supply and return water of the smart energy valve control loop (terminal equipment), and the measured temperature is uploaded to the Internet of Things controller. The Internet of Things controller can calculate the supply and return water temperature difference based on the measured temperature, and measure the energy value of the controlled loop in real time based on the measured flow and temperature difference. The valve body only adjusts the flow rate according to temperature and load changes, and is not affected by system pressure fluctuations, ensuring that the flow rate and the position of the smart actuator only change when the load demand changes.

[0023] 2. The two ends of the valve body are connected by flanges or threads to achieve quick disassembly and installation of the valve body and the pipeline.

[0024] 3. The first water pressure sensor and the second water pressure sensor installed on the pipeline are arranged before and after the valve body, and the pressure sensor and the Internet of Things controller are connected to each other through wires. The first water pressure sensor and the second water pressure sensor are used to detect the pressure before and after the energy valve, and the measured pressure is uploaded to the Internet of Things controller. The Internet of Things controller can calculate the pressure difference before and after the valve according to the measured pressure. The BMS building automation can adjust the water pump frequency according to this data, reduce it to the minimum pressure difference at the most unfavorable end required for system operation, and reduce the energy consumption of the water pump. The relevant parameters can be read online in real time, which brings convenience to users.

[0025] 4. The smart actuator, the first water temperature sensor, the second water temperature sensor, the first water pressure sensor and the second water pressure sensor can all be connected to the controller signal, and are further preferably connected to each other through wires. Through the Internet of Things controller, the calculation data of the valve body smart actuator, the first water temperature sensor, the second water temperature sensor, the first water pressure sensor and the second water pressure sensor can be read. And the relevant parameters are calculated and output as energy value, temperature difference and pressure difference. Upload to the BMS control room through the communication protocol, or read relevant operating data online through mobile phone Bluetooth or wifi, power carrier, etc. The Internet of Things controller is connected to these devices through wires. The control instructions are all issued by the Internet of Things controller, and the devices are connected through wires. The Internet of Things controller can transmit the relevant data remotely through the communication protocol, thereby realizing the Internet of Things function.

[0026] 5. When the valve body is at different openings, the water flow of the valve body is the calibrated flow value, and the different openings are accurately controlled by the smart actuator. The flow values ​​of the corresponding openings are solidified in the smart actuator. The IoT controller can instantly read the flow value of the valve body at the corresponding opening.

[0027] 6. The IoT controller is equipped with Bluetooth, WiFi, and power carrier modules. The IoT controller can read flow, energy, temperature, pressure, temperature difference, pressure difference and other operating parameters on-site through Bluetooth and mobile phone App. The dynamic balancing electric regulating valve shields the pressure fluctuation and interference of the water system (pressure is irrelevant). At the same time, it also reduces the difficulty of hydraulic balancing and debugging of the balancing valve, ensures the constant flow of the area or equipment, and displays the water flow through the valve in real time. Through the temperature sensor on the supply and return pipes, the supply and return water temperature and temperature difference, the pressure and pressure difference before and after the valve are monitored in real time. The IoT controller can automatically adjust the valve opening according to the measured data to ensure operation with an economical temperature difference.

[0028] The IoT controller can upload relevant data (flow, heat and cold, temperature difference, pressure difference, etc.) to the building control system. Through the relevant data monitored by the system software, the performance of each device and coil can be monitored online, and the energy usage of the equipment can be calculated. The coil performance can be optimized by adjusting the control valve, the water pump flow can be reduced, and the water pump operation frequency can be optimized based on the measured pressure difference to reduce the water pump energy consumption. The software can automatically analyze the relevant data based on the historical operation data parameters of the project, and propose energy-saving optimization operation plans and reasonable measures to improve the working condition operation.

[0029] The device can be connected to the cloud platform through simple settings, and the relevant parameter data can be stored in the cloud. The operation data can be analyzed online, which is conducive to energy-saving analysis, and historical data reports can be exported. Secondary development and upgrade of the platform can be carried out according to customer needs.

[0030] 7. The present invention sets a partition inside the valve body to separate the water inlet channel and the water outlet channel. The partition includes a horizontal flow portion and a connecting portion that connects the flow portion to the inside of the valve body. The flow portion is provided with a water hole. The bushing is threadedly connected to the inner wall of the water hole, which is convenient for quick replacement and installation of the bushing. By customizing the inner diameter of the bushing, the maximum diameter of the water flow can be adjusted to meet the use needs of different users. The valve core can be lifted and moved under the action of the valve stem. The shape of the valve core is truncated cone, and the diameter of the valve core gradually decreases from top to bottom. When the valve core moves upward, the annular ring width formed between the valve core and the inner wall of the bushing gradually increases, thereby increasing the opening component of the valve body. The sealing of the bushing and the inner wall of the water hole is ensured by the first sealing ring and the second sealing ring; the sealing of the valve core and the inner wall of the bushing is ensured by the sealing ring and the sealing protrusion. The guide block and the valve stem are filled into the ball groove through the ball body so that the valve stem and the guide block maintain an integrated performance and are lifted and lowered together, and the valve stem can rotate relative to the guide block. The lifting and lowering movement of the valve stem can be achieved by: the gear and rack meshing transmission of the valve stem outside the valve body; or a ball screw transmission method, where the screw rotates to achieve linear motion of the screw. The power device that drives the valve stem to lift and lower is set inside the IoT controller, and the upper end of the valve stem extends into the IoT controller. BRIEF DESCRIPTION OF THE DRAWINGS
