Description

technical field [0001] The invention relates to the field of valves, and more particularly, to an intelligent pressure reducing valve integrating the functions of power generation and data acquisition. Background technique [0002] At present, global resources are in short supply, and various energy sources such as water resources and gas sources are in a state of shortage. For water resources, the concept of smart water affairs came into being. How to save water and achieve effective leakage control, among which the United States and Italy have successively put forward some advanced pressure valves with flow detection function, which can control the leakage as small as possible, but their flow detection device needs an external power supply or battery, and relies on external power supply, and it only needs to check the flow parameters. Detection, low power consumption. However, smart water affairs is far from limited to leakage control. It also needs to measure various par...

Problems solved by technology

However, smart water services are not limited to leakage control, but also need to measure various parameters such as water quality in order to make a comprehensive evaluation of the water flowing in the valve. Therefore, it is necessary to add various types of testing instruments. At this time, simply set the external power supply Or the battery can no longer fully drive all kinds of testing instruments to operate at the same time. If in order to achieve the effect of comprehensive power supply, it is necessary to carry out complex design on the external power supply or battery, which results in a large amount of engineering, high cost and troublesome maintenance in the later stage.

[0003] There are also related cases of hydropower generation in the prior art, but it is only the combination of hydropower generation and valves, and does not involve the detection module, that is, there is no case in the prior art that uses the electric energy of hydropower generation to power the detection module

At the same time, the current water power generation technology in the prior art mainly uses the force of the fluid to directly drive the turbine to rotate. The prior art also uses a spherical runner to drive the electromagnetic induction generator to generate electricity, but the turbine does not specifically target the process of the water flow. The flow is related to the design, that is, when the water flow is large, it will have a large impact on the turbine, which may cause damage to the turbine. At the same time, due to the uneven water flow, the electromagnetic induction generator is unstable when flowing through the turbine, which will directly affect The service life of its rechargeable battery
