Hangfang is one of the important gearbox industry bases in China. Recently, another advance research and development technology of the Hangzhou Advance Gearbox Group "J035 ultra-high speed gearbox" won the national utility model patent.
Where is the surprising result of this invention? The JO35 ultra-high speed reducer project is mainly used in solar thermal power generation systems. This project not only generates electricity, but also provides various functions such as heating and hot water, energy saving and environmental protection, and it is said that it has filled China's super High-speed gearbox design and manufacturing space. In addition, reducers can also be widely used in geothermal energy, industrial waste heat and other efficient energy use.
It is understood that the JO35 ultra-high speed reducer recommended by the Technology Association of the Hangzhou Tooth Technology Co., Ltd. won the gold medal in the 4th China Cross-Strait Workers' Innovation Achievement Exhibition in 2010.
Silent Check Valve
Space of the valve cavity employs streamlined design, overcoming turbulent flow of the media.
The spherical structure at the front part of the discs and beveled sealed surface reduce impacts on media and also the flow -resistant coefficient.
The inner guide vane adopts a style of thin eggshell so as to ensure the flow of the media unblocked. At the same time, the weight of the valve reduces as well.
A largest flowing sectional area is created by reasonably lifting the height and enlarging the inner space, which also effectively avoid the produce of an air-chamber, upgrade the valve`s Cv value and overcome noise.
