Today we are going to focus on manufacturers to tell you about the relevant multi-leaf blast of air flow control valve structural features, to know that a majority of users of this knowledge is more concerned in understanding this knowledge, we can understand that it's safer applications. Let's look at the specific, as follows: Characteristic (l) of the air flow control valve in the unity of the whole blade width four sizes, leaf-shaped diamond-shaped double blades, vanes between soft lap 18,605,342,909, so good airtight performance. Features (2) air volume control valve body frame with an electric pressure delivery after 2 mm cold rolled galvanized sheet molding air, carbon dioxide gas welding or welding by ordinary Q235 plate processing; blades with 1 mm cold rolled galvanized sheet for corrugated, two synthetic spot-square shaft inserted, or 2 mm G235 steel cold forming, punching chip interpolating axes or welding circular shaft. Features (3) of the valve sub-manual, electric, divided according to the materials used: iron, galvanized sheet, aluminum plate, stainless steel four, the same body structure and size specifications. For more information about multi-leaf outlet of knowledge that we will continue to bring you organize, please look forward to when it comes to positive outlet we should not unfamiliar stairwell pressure delivery outlet, now positive outlet to bring our lives a great convenience, because life often use pressure delivery outlet, so manufacturers can also be customized to produce the required specifications. Pressure delivery outlet is characterized by flexible operation, low noise, leaking a small amount (closed type leakage <0.5%) Operating temperature region wide, reliable structure, safe and convenient. On the other hand we know can do open air grille Fire positive outlet for aluminum alloy, anodized surface, in accordance with user requirements or electrostatic spray paint, color according to user choice. Positive outlet blade angle can be in the range of 0 to 90 adjustments for different air diffusion distances and angles. And it can be coupled with user requirements regulating valve or filter. Pressure delivery outlet using stainless steel, and it has smooth as a mirror, excellent workmanship and shiny texture advantage. And that the material is not easy deformation, super corrosion resistance.
