A multifunctional fully automatic pressure reducing valve and its control method

Abstract

The invention belongs to the technical field of valves and discloses a multifunctional full-automatic pressure reducing valve. The pressure reducing valve comprises a valve body, wherein an actuator used for controlling the opening degree of the valve body; the pressure reducing valve also comprises a power generation device, a data collection component and a data processing device; the power generation device comprises a power generation component arranged inside the valve body and a battery component arranged outside the valve body; the data collection component is arranged in the front of the valve body, and / or is arranged inside the valve body and or is arranged in the back of the valve body; the data collection component is used for collecting medium parameters in the valve body and transmitting the parameters to the data processing device; the data processing device is used for controlling the actuator to work according to the real-time parameters provided by the data collectioncomponent; the power generation device is used for supplying working power to the data collection component, the data processing device and the actuator. The pressure reducing valve has a data collection function and is capable of generating power by using the self kinetic energy of the circulation medium in the pressure reducing valve, supplying the working power to the data processing componentand the actuator of the pressure reducing valve; the self-sufficiency of electric energy of the multifunctional pressure reducing valve is achieved; the external power supply is not needed.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a multifunctional automatic pressure reducing valve 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 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 parameters such as water qu...

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.
