The high-pressure hydrogen storage bottle neck pressure reducing valve has very high technology, and the high-end market has always been monopolized by European and American companies.
SHWS Hydrogen Energy Technology Corporation is committed to the R&D and manufacturing of storage and transportation systems for hydrogen fuel systems.
The products cover hydrogen storage system, fuel cell stack, hydrogen storage tank valve system, etc.
In June 2020, SHWS launched China's first 70MPa multi-functional integrated pressure reducing valve group product certified by a third-party authority, overcoming the problems of high efficiency, high reliability and high safety for hydrogen storage, and announced that it has filled the gap of Chinese enterprises in the field of high-pressure valves. Another key technology gap.
Safety, energy saving and environmental protection are the three major labels for the application of hydrogen fuel cell technology, and the pressure reducing valve is the most critical part of safeguarding safety.
According to reports, high safety, high integration, high reliability and long life have been well reflected in the 70MPa multifunctional integrated pressure reducing valve group product.
The technology platform of SHWS contains more than 100 enterprise standards, more than 500 hardware requirements, more than 5000 software requirements, thousands of tests and tens of thousands of tests. Relying on this positive R&D platform system, fuel cell engine systems, components and materials can be quickly defined, decomposed, simulated and designed from top to bottom according to customer needs, and the high performance, high quality and low cost of products can be ensured through trial production experiments. cost.
On the R&D side, SHWS has built an international-level integrated supply chain ecology of "manufacturing-storage-transportation-plus-application", successfully connecting the upstream and downstream industrial chains, and effectively reducing or sharing R&D costs through the coordinated integration of resources.
On the production side, SHWS reduces the number of integrated parts while reducing the manufacturing cost by optimizing the structural design and improving the integration level for the design and production of pressure reducing valve products.
The 70MPa multi-functional integrated pressure reducing valve group product has a development cycle of 31 months. According to the operating conditions of the whole vehicle, the efficient operation of the system and the technical requirements of safety performance, a total of 17 categories of more than 1000 bench tests have been carried out, including hydraulic blasting. A number of key tests such as testing, hydraulic cycle testing, high and low temperature internal and external leakage tests, etc., and supporting a variety of hydrogen fuel cell models to complete a number of vehicle-level performance tests such as winter calibration and cruising range, and use a large number of measured data to interpret safety performance , Verified the excellent quality.
In the most critical leak test link, through the routine high and low temperature internal and external leakage tests, the whole life cycle pure hydrogen test is less than 100ppm, the hydrogen leakage rate is less than 0.6Nml/h, and far exceeds the leakage index of the general standard guidelines at home and abroad <10Nml/h , redefines the industry's "hydrogen safety" standard.
