Multifunctional pressure reducing valve capable of stable self-generation

Abstract

The invention belongs to the technical field of a valve, and discloses a multifunctional pressure reducing valve capable of performing stable self power generation. The multifunctional pressure reducing valve comprises a valve body which is internally provided with an actuator for controlling aperture of the valve body. The multifunctional pressure reducing valve further comprises a power generating device, a data acquisition assembly and a data processing device. The power generating device is used for supplying working power to the data acquisition assembly, the data processing device and adisplaying terminal. The data acquisition assembly is arranged in front of the valve and / or in the valve and / or behind the valve. The data acquisition assembly acquires a medium parameter in real timeand transmits to the data processing device. The data processing device makes the actuator operate according to the supplied real-time parameter. The power generating device comprises a power generating assembly and a battery assembly. The front side wall and the back side wall of the valve are respectively provided with a connecting hole. The two connecting holes are connected through an external pipe. The power generating assembly is arranged in the external pipe. The battery assembly is arranged outside the external pipe. The inner diameter of the external pipe matches the outer circumference of an assembly housing. The pressure reducing valve has a data acquisition function and furthermore can utilize the kinetic energy of a flowing medium for generating power, thereby supplying working power to the data acquisition assembly and the actuator.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a multifunctional decompression valve capable of stabilizing self-generating power and a control method thereof. 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 has emerged as the times require. How to save water and achieve effective leakage control, among which the United States China and Italy have successively proposed some advanced pressure valves with flow detection function, which can control the leakage as small as possible, but the flow detection device needs an external power supply or battery, which depends on the external power supply, and it only needs to control the flow parameters. Detection, low power consumption. However, smart water services are not limited to leakage control, but a...

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 flow power generation technology in the prior art mainly uses the force of the fluid to directly drive the turbine to rotate, thereby driving the electromagnetic induction generator to generate electricity, but the turbine is not specifically designed for the flow of water flow, that is, when the water flow is large, it will A large impact on the turbine may cause damage to the turbine. At the same time, due to the uneven water flow, the electromagnetic induction generator will not generate electricity when it flows through the turbine, which will directly affect the service life of its rechargeable battery.
