The national standard “High pressure hydrogen storage cylinder combination valve for vehicles” was officially released
Bus network was informed on June 6, 2023, approved by the State Administration for Market Supervision and Administration (National Standardization Administration Committee), “Vehicle high-pressure hydrogen storage cylinder combination valve” (GB/T 42536-2023) was recently officially released, the standard is centralized by the National gas cylinder standardization Technical Committee, It is implemented by the Automotive high-pressure Fuel Cylinder branch of the National Gas Cylinder Standardization Technical Committee, and will be implemented on June 1, 2024.
The standard is jointly drafted by China Special Equipment Testing and Research Institute, Dalian Boiler and Pressure Vessel Inspection and Testing Institute Co., LTD., Zhejiang University, Weishi Energy Technology Co., LTD., Tehi Hydrogen Testing (Baoding) Co., Ltd. and other influential authoritative scientific research institutions and hydrogen energy enterprises in the industry.
This is also after participating in the preparation of a number of “hydrogen valve” group standards, Weisei Energy once again participated in the preparation and development of national standards, marking Weisei Energy has taken another solid step in the construction of hydrogen energy technical standard system.
As one of the hydrogen energy enterprises, Weizei Energy passed the screening of the relevant departments, and had the honor to participate in the formulation of the national standard, and Wang Dongyu, the national technical subject leader and senior expert on hydrogen storage technology of Weizei energy, deeply participated in the preparation of the standard based on his own years of experience in hydrogen storage and supply technology and independent research and development and application verification results of Weizei energy hydrogen valve products. Focus on valve sealing, structural design, pressure test, test methods, acceptance standards, etc., to participate in the development of standards and provide targeted professional advice.
The standard for the first time in the country to unify the automotive high pressure hydrogen storage cylinder valve test methods and technical specifications, clear hydrogen valve products related quality standards, the release and implementation of the standard will help China’s automotive high pressure hydrogen storage cylinder valve products to follow the standard as the fundamental, continue to iterate and upgrade, to fuel cell vehicles high quality development, leading the hydrogen energy industry to forge ahead.
Pressure reducing valve, bottle valve
Focusing on the research and development and industrial application of hydrogen storage and transportation technology, hydrogen storage products and core components, Wepotential Energy continues to innovate in the field of hydrogen valve subdivision, achieving full category coverage of hydrogen valves, and achieving innovative breakthroughs in the field of high pressure hydrogen storage valves, and independently developed and launched a number of representative products such as 70MPa high pressure bottle valve and 70MPa pressure reducing valve. The comprehensive performance standards are in line with the European Union, and the safety standards far exceed the general safety standards at home and abroad, covering the standard flow rate of 35MPa/70MPa and the large flow pressure range of the vehicle hydrogen storage system, and have a complete set of hydrogen storage system hydrogen valves for commercial vehicles and passenger vehicles, customized development and large-scale production and supply capabilities.
In addition, based on the high efficiency storage and application requirements of liquid hydrogen technology, Wepotential Energy has successively broken through key technical problems such as ultra-low temperature adaptive internal leakage sealing technology in liquid hydrogen temperature zone and low-power electromagnetic drive technology in the development of vehicle liquid hydrogen valve, developed and completed a series of valves such as automotive liquid hydrogen flow valve and electromagnetic liquid hydrogen stop valve, and carried out vehicle tests with liquid hydrogen system. Product safety and effectiveness have been fully verified.
The participation in the development of national standards, highlighting the potential energy in the field of hydrogen valve technology innovation ability and product development ability has been in the forefront of the industry, confirmed the industry and relevant institutions of the potential energy high affirmation and recognition, but also the potential energy in the field of standard development of a high-standard breakthrough, marking the potential energy in the field of hydrogen valve is seizing the commanding heights of scientific and technological development, It will help non-potential energy to further seize market opportunities and occupy more industry discourse power.
