In remote areas and off grid power supply scenarios, traditional valve control systems are often limited due to unstable power supply or high costs. The emergence of solar wind solar complementary electric valves provides an efficient and environmentally friendly solution for fluid control by integrating wind and solar power generation technologies. The following analysis will be conducted from two aspects: working principle and application scenarios.

1、 Core working principle: Dual energy complementarity and intelligent regulation

The core of the solar wind solar complementary electric valve is to combine wind turbines with solar panels to form a complementary power supply system. Its working principle can be divided into three stages:

Energy harvesting stage

When there is sufficient sunlight, solar panels convert light energy into electrical energy, providing power to the valve actuator and charging the battery at the same time; When there is insufficient sunlight at night or on rainy days, the system automatically switches to wind power generation mode, converting wind energy into electrical energy through wind turbines. This dual energy complementary mechanism ensures that the system24Stable power supply within hours.

Intelligent management stage

Electric energy management controller as a system“brain”Real time monitoring of light intensity, wind speed, and battery capacity. When there is an excess of solar power generation, the controller stores the excess electrical energy in the battery; When wind power generation is sufficient, the system can prioritize using wind power to reduce reliance on batteries. For example, the products of Shanghai Huquan Valve Group Co., Ltd. optimize energy allocation through intelligent algorithms, enabling the system to maintain continuous rainy and cloudy days72Stable operation for over hours.

Valve control phase

The electric valve actuator receives instructions from the controller or remote terminal and drives the valve to open and close through an intelligent brushless motor. The motor adopts a low heat design, combined with a wireless communication module (such asLORATechnology enables remote control of multiple terminals such as mobile phones and computers. For example, in a certain water conservancy project, management personnel use their mobile phones to access informationAPPReal time adjustment of the flow rate of cross basin water transfer pipelines, reducing response time to3Within seconds.

2、 Typical application scenario: Green coverage from wilderness to city

Infrastructure in remote areas

In areas without power grid coverage such as Gobi Desert and plateau, wind solar complementary electric valves are widely used in fields such as water conservancy irrigation and natural gas transportation. For example, a wind farm in Inner Mongolia has used this technology to control the valves of gas pipelines, saving more diesel power generation costs annually20Ten thousand yuan, while reducing carbon emissions150Ton.

Municipal and Industrial Automation

In urban water supply systems, this valve can replace traditional electric valves and achieve automatic pressure regulation of the pipeline network. A case study of a certain water management group shows that the system has passedGISPositioning and abnormal alarm function, reducing the leakage rate of the pipeline network from12%drop to5%During the annual festival, the water level exceeded300Ten thousand cubic meters.

Environmental Protection and Emergency Response

In scenarios such as ecological protection monitoring stations and temporary disaster relief sites, wind solar complementary electric valves provide independent power for sewage treatment equipment and emergency water supply systems.2024In the rescue of a certain earthquake in the year, this technology ensured the temporary water supply valve in the disaster area7224-hour uninterrupted operation, recognized by the Emergency Management Department.

3、 Technological advantages and future trends
