русскийThe chemical and physical composition of fine dust composed of interactions of sulfur oxides, nitrogen oxides, volatile organic compounds, and other compounds in ambient air varies by location, climate, and season of year. Respirable particles typically come from vehicles moving on unpaved or cemented roads, the shredding process of materials, and dust blown by the wind. Total suspended particles are the general term for solid and liquid particles suspended in the air, the particle path plan is about 0.1-100 microns, the particle size is large or the color is black and visible to the naked eye.
The maneuverability is ahead of over-valve and flammable high-pressure ball valve, especially in high-risk pipelines, electric high-pressure valve can play a powerful role. The multi-channel ball valve can not only flexibly control the confluence, diversion and flow conversion of the medium in the pipeline, but also close one of the two channels and connect the other two channels.
