The miniature electric valve plays a role in controlling the flow of hydrogen in the hydrogen energy storage system. A hydrogen energy storage system usually includes three links: hydrogen storage, hydrogen delivery, and hydrogen utilization. Hydrogen pipelines and valves need to be used to control the flow of hydrogen during hydrogen delivery. The miniature electric valve has the advantages of small size, light weight, corrosion resistance, and convenient operation. It can accurately control the flow and pressure of hydrogen to ensure the safety and effectiveness of hydrogen delivery. Therefore, in the hydrogen energy storage system, the miniature electric valve plays a vital role.
Miniature motorized electric ball valves refer to electric valves with compact structure and small volume, which are often used to control and adjust the flow and pressure of various media. In clean energy equipment, miniature electric valves are widely used in fluid control during the collection, conversion and utilization of solar energy, wind energy, biomass energy and other energy sources.
For example, in a solar water heater, a miniature electric valve controls the flow and direction of the heating medium to ensure that the water in the water tank is always within an appropriate temperature range. In wind power generation equipment, miniature electric valves are used to control the speed and angle of the wind rotor to ensure the maximum conversion efficiency of electric energy. In biomass power generation equipment, micro electric valves are used to adjust gas flow and gas pressure to ensure complete combustion of fuel and maximize power generation efficiency.
In addition to the above applications, miniature electric valves can also be used for fluid control and regulation in other clean energy equipment, such as the manufacture of solar photovoltaic cell components, hydraulic control of various new energy vehicles, and medium transportation in geothermal energy utilization. Overall, miniature electric valves play an important role in clean energy equipment, contributing to energy transition and low-carbon economic development.

4. Miniature electric valves play an important role in controlling the working parameters of fuel cells. Fuel cells usually need to work properly under specific temperature, pressure and flow, and micro electric valves can be used to control the entry and exit of hydrogen and the discharge of reaction products, thereby controlling temperature, pressure and flow. In addition, the electric valve can also be used to control the start-stop and switching of the fuel cell system.
6. As an important safety control device, miniature electric valves usually have a variety of safety functions, such as power-off hold function, overload and overheat protection function, automatic emergency stop function, etc. These functions can improve the security performance and reliability of the equipment.
In the control of the working parameters of the fuel cell, the micro electric valve can provide precise control, effectively adjust the engine combustion, optimize fuel consumption, and achieve energy saving effect; in the hydrogen energy storage system, the combination of the micro electric valve and the safety circuit can Effectively control and prevent hydrogen leakage to protect personal safety.

In the hydrogen energy storage system, electric valves of the following specifications are mainly used:
1. Electric ball valve: generally used in pipelines with large flow, which can realize the functions of fast switching and flow adjustment.
2. Electric butterfly valve: It is often used for pipeline control of gas and liquid media, and is generally used in small and medium flow pipelines.
3. Electric gate valve: mainly used to control the flow of gas or liquid medium, especially for high-pressure pipelines, electric gate valve is a necessary control device.
4. Electric cut-off valve: mainly used to cut off the medium flow in the pipeline, with the advantages of good stability and strong sealing performance.
In clean energy equipment, on-off electric valves are used more. This is because clean energy devices often require precise flow control to function properly and efficiently. The on-off electric valve can realize fast and accurate flow control, which is simpler and more convenient than the regulating electric valve.
The on-off electric valve has only two states - fully open or fully closed, so it is not suitable for occasions that require precise flow adjustment. The regulating electric valve can adjust the opening of the valve according to the needs to achieve precise control, but it requires more control and calculation, and more energy to maintain a stable opening. Therefore, in clean energy equipment, on-off electric valves are more common.
The emergence of clean energy equipment is the result of the efficient use of energy in today's society. The application of micro electric valves has promoted the development of clean energy equipment and plays an irreplaceable important role. Although the application range of miniature electric valves continues to expand, the development still requires the support and promotion of professional technology and innovative thinking.
