Hanging ball valve pneumatic butterfly valve is a pneumatic butterfly valve for lifting equipment. The quality is related to the safety of equipment and also bears the weight of equipment, so the selection of hanging ball valve pneumatic butterfly valve is very critical.
Dongfeng suspended ball valve pneumatic butterfly valve is processed by stamping, combined with synthetic parts and components, and its appearance is treated by electrostatic coating. It has passed the salt spray test and strict quality control; The structure is beautiful, and CR materials are added at the upper and lower ends to further isolate vibration and noise. It is used for suspended air conditioning equipment, fans, large and small pipelines and other suspended equipment. Suspended ball valve dampers are widely and well used in the market. After years of R&D and improvement by the manufacturer, the valve effect can basically reach 95% - 100%. It is applicable to vibration reduction and isolation of suspended equipment such as suspended fans, suspended air conditioning boxes, suspended air ducts, suspended water pipes, suspended ceilings, etc.
Applicable equipment: ceiling air conditioner, axial flow fan, fresh air fan, pipeline and other hoisting equipment
Damping ball valve pneumatic butterfly valve is a damping controllable structure that works depending on the rheological characteristics of magnetorheological fluid itself. The output of damping pneumatic butterfly valve mainly depends on the performance of magnetorheological fluid, the size of damping pneumatic butterfly valve and the type of damping pneumatic butterfly valve. The flow form and stress state of MR fluid are different, so the working mode of MR damper pneumatic butterfly valve can be divided into flow mode (FlowMode, also known as pressure driven mode), shear mode (ShearMode), squeeze mode (SqueezeMode) and any combination of these three basic modes.
(1) Flow mode (also known as pressure driven mode, or valve type)
This is a working mode that has been widely used so far. The magnetorheological fluid is filled between the two stationary plates. The external magnetic field acts on the magnetorheological fluid between the two plates vertically through the two plates, changing the flow performance of the magnetorheological fluid, thereby changing the resistance of the piston driving the flow of the magnetorheological fluid, so as to achieve the purpose of controlling the damping force by the external magnetic field. The system can be used for servo control valve, damping pneumatic butterfly valve, shock absorber, etc.
(2) Cut Mode
The principle of shear mode magnetorheological damping pneumatic butterfly valve is similar to that of flow mode. The magnetorheological fluid is filled between the two opposite moving plates. The external magnetic field acts on the magnetorheological fluid between the two plates vertically through the plates, changing the flow performance of the magnetorheological fluid. The upper and lower plates move at a relative speed v, and the movement direction of the magnetic plate is perpendicular to the direction of the magnetic field, so as to control the damping force. This system can be used for magnetorheological devices such as clutch, brake, locking device, machine tool fixture and damping pneumatic butterfly valve.
(3) Extrusion mode
