Pneumatic swing valve,Its material is 45 and Q345 ect,for the Pneumatic Conveying System:
The working principle:
Pneumatic actuators by rotation and swing arm turn the valve plate, valve plate and the sealing surface load between the spiral compression spring, spring force keeps the valve plate seal face and sealing ring surface fit closely, and allow the valve plate in the vertical direction, so as to help compensation valve parts of heat bilges cold shrink, and any back pressure change on the influence of the seal, it also can prevent the granular medium into the surface. Valve plate seal face sealing ring surface friction in the tangent direction can make the difference between the valve plate rotation in the process of opening and closing, this feature makes between the sealing surface grinding, polishing effect is produced. All these characteristics make the swing valve has a long service time and provided the reliable safeguard for your system security.
The valve adopts hard alloy friction pair or toughening ceramic friction pair structure, with strong wear resistance and good sealing, small startup load, the valve cavity no dust, no card plug phenomenon, long service time.
