Liquid hydrogen ultra-low temperature high-pressure solenoid valves: In recent years, our country has been seeking sustainable new energy sources – green energy. Hydrogen energy has emerged as an alternative to traditional coal and other polluting energy sources used in the chemical industry. However, due to the late start of hydrogen energy development in our country, many of the key components for hydrogen energy equipment still have to be imported； By \"high pressure\" we mean values such as 35MPa, 70MPa, and 100MPa. This applies to high-pressure explosion-proof hydrogen solenoid valves (35MPa, 70MPa), hydrogen storage tanks (carbon fiber-based), as well as compressors, filters, sensors, and other related products. Shenzhen Deteng Electromechanical Equipment Co., Ltd. specializes in high-pressure, leak-free fluid components, including high-pressure explosion-proof solenoid valves, carbon fiber gas storage tanks, and filters. These products are widely used in various hydrogenation units, CNG, LNG systems, as well as in applications involving ultra-low temperatures and high pressures. They boast the advantages of a compact design, light weight, few moving parts, easier maintenance, and lower costs. Among the key components used in hydrogen energy applications is the carbon fiber gas storage tank; Shenzhen Deteng Electromechanical Equipment Co., Ltd. offers models with a pressure rating of 70MPa. Their solenoid valves also have high-pressure explosion-proof capabilities at 70MPa or 105MPa, while their filters can handle pressures of 150MPa with a precision of 10μm and a pressure drop of less than 50PSIg. The company also provides high-pressure solenoid valves for liquid hydrogen, liquid nitrogen, and liquid oxygen, as well as solenoid valves designed for ultra-low temperature and high pressure conditions, using special materials that allow operation at temperatures as low as -250°C℃ ； High-pressure ultra-low temperature solenoid valves are designed using special control principles, featuring direct-acting switch control for fast response times. The maximum operating pressures vary depending on the flow rate: 10 Mpa, 70 Mpa, 103.4 Mpa… In today’s economic landscape focused on reducing carbon emissions, hydrogen energy will become one of the key energy sources. To meet the space constraints imposed by equipment, hydrogen needs to be stored and transported in liquid form; this liquid hydrogen is in an ultra-low temperature state, and therefore ultra-low temperature solenoid valves are required for such storage and transportation tasks. Our solenoid valves can meet these requirements, offering a service life of over 1 million cycles along with zero-leakage reliability. Ultra-low temperature high-pressure solenoid valves are core components in the storage and transportation of liquid hydrogen. Key technologies for the production, storage, and transportation of liquid hydrogen. The production, storage, and transportation of liquid hydrogen involve many core components and key technologies. The equipment used for liquefying hydrogen includes core components such as helium turbine expanders, low-leakage heat exchangers, helium screw compressors, ultra-low temperature solenoid valves, and ortho-para hydrogen converters. Meanwhile, the process of storing and transporting liquid hydrogen places high demands on devices such as liquid hydrogen pumps, liquid hydrogen storage tanks, and liquid hydrogen tank trucks. The helium turbine expander is the core component of the helium-refrigerated hydrogen liquefier; it determines the liquefaction capacity, energy consumption, and stability of this system. It needs to reach a speed of over 100,000 revolutions per minute at temperatures below 50K, withstand the impact of high-pressure, high-speed air streams at 20 bar, and achieve an adiabatic efficiency of over 65%. Therefore, gas bearings with gas lubrication are used, and extremely high requirements are placed on machining precision; often, five-axis precision CNC machines are required for processing. After liquid hydrogen is transported to the liquid hydrogen refueling station, the key issue is how to move it to the hydrogenation equipment and pressurize it; in this regard, liquid hydrogen pumps represent an option with significantly higher energy efficiency compared to hydrogen compressors. Liquid hydrogen pumps were previously used mainly in the aerospace sector to supply low-temperature liquid hydrogen fuel to spacecraft; they are essentially large turbine pumps, with turbines serving as the power source to drive the pump. Currently, liquid hydrogen pumps are gradually shifting towards civilian applications. Research on small liquid hydrogen pumps has a history of many years; abroad, companies such as Linde have successfully developed high-pressure liquid hydrogen piston pumps. Its technical features are: compact size, allowing it to fit inside a 20-foot container ； Single-stage compression ； The maximum filling capacity reaches 120 kg/h ； The minimum input pressure reaches 2 bara ； The maximum output pressure reaches 900 bar ； Noise level below 74dB(A) ； The export status is liquid. And when liquid hydrogen arrives at the customer’s site, a storage tank for liquid hydrogen is required to hold it. As a cryogenic liquid storage tank, the liquid hydrogen tank must be insulated in order to minimize evaporation losses caused by heat leakage. For liquid hydrogen storage tanks, the vacuum multi-layer insulation currently offers the best thermal insulation properties and is the most widely used; it is considered the best insulation method available today. The daily evaporation rate of a high-performance 100 m3 liquid hydrogen tank is approximately 0.5%. A typical liquid hydrogen storage tank uses stainless steel as the material for its inner lining; the lining is supported by internal components, which must have good thermal insulation properties in order to meet the tank’s insulation requirements. The internal component is fixed by being welded at one end to the circular iron groove at the bottom of the tank’s inner lining ； The other end is connected to the support frame at the bottom of the tank shell via screws. https://cbu01.alicdn.com/img/ibank/O1CN01CAHlqv1uRcWzcmkYW_!!934146034-0-cib.jpg A negative pressure solenoid valve is essentially a vacuum solenoid valve; in fact, both negative pressure and vacuum solenoid valves require a leakage rate of zero ； Only in this way can vacuum extraction and operation under negative pressure be ensured. Therefore, for a negative pressure solenoid valve, it is essential that its leakage rate be zero. How is the leakage rate of such a solenoid valve determined? It is based on the negative pressure value of the valve Normally, negative pressure solenoid valves require a very low leakage rate; they are also known as zero-leakage solenoid valves, negative pressure solenoid valves, or vacuum solenoid valves. There are also micro-high-frequency solenoid valves and high-frequency solenoid valves, with a maximum frequency of 100 Hz or 200 Hz ； High-frequency solenoid valves can be used for pressure compensation, as well as as regular solenoid valves to regulate flow and compensate for pressure. High-frequency solenoid valves are cheaper than regular ones and yet reliable. Our leak-free solenoid valves are designed specifically for analytical instruments, environmental testing equipment, biochemical instruments, and custom leak detection devices; they operate in a pressure range of vacuum to 15,000 PSI (104 MPa), with diameters ranging from 0.5 mm to 50 mm, and support a wide range of power sources.
