Problems solved by technology

The valve cannot be solved by the interference of hydraulic imbalance (that is, there is no dynamic hydraulic balance function), which brings inconvenience to users
[0004] 2. The existing energy valve only has the function of temperature monitoring, and cannot perform constant water temperature difference control in real time
[0005] 3. The existing energy valve needs to use other means (flowmeter) to detect the flowing flow, and it needs to install a corresponding flowmeter when monitoring the flow, which brings inconvenience to the user.
[0006] 4. The temperature difference ΔT between the inlet and outlet of the heating or cooling equipment (controlled loop) is too small, resulting in a decrease in the efficiency of the equipment (loop) and an increase in the input power of the water pump
The flow and energy data measured by the energy meter cannot be linked with the control valve, and cannot solve the operating conditions of large flow and small temperature difference
Control valves and building automation cannot achieve optimal control according to actual parameters

Abstract

The invention discloses an intelligent energy valve with dynamic balance and energy-saving internet-of-things functions, and relates to the technical field of energy valve devices. The intelligent energy valve with the dynamic balance and energy-saving internet-of-things functions comprises a valve body mounted on a pipeline; an intelligent actuator is arranged at the upper end of the valve body;the valve body is provided with a plurality of opening degrees; the opening degrees of the valve body are controlled by the intelligent actuator; the intelligent actuator is connected with an Internet-of-Things controller; and a first water temperature sensor and a second water temperature sensor which communicate with the pipeline are arranged on the front side and the rear side of the valve bodycorrespondingly. As the valve body receives temperature and load changes to adjust the flow, the valve body can automatically stabilize the pressure difference between the two sides, so that the influence from system pressure fluctuation is avoided, and it is guaranteed that the flow and the position of the intelligent actuator only change according to load requirements.

Description

technical field [0001] The invention relates to the technical field of energy valve devices, in particular to an intelligent energy valve with dynamic balance and energy-saving IoT functions. Background technique [0002] The energy valve is a commonly used valve body in the prior art, but the existing energy valve has the following disadvantages: [0003] 1. The existing energy valve does not have the function of dynamic balance. The structure of the valve body is ball valve, butterfly valve and seat valve. The valve authority is 0.3-0.6, and the flow characteristic curve has a large deviation in actual use. It has a relatively large impact on the regulation performance. The valve is disturbed by the hydraulic imbalance and cannot be solved (that is, there is no dynamic hydraulic balance function), which brings inconvenience to the user. [0004] 2. The existing energy valve only has the temperature monitoring function, and cannot perform constant water temperature differ...
