The electric butterfly valve of the suspended butterfly valve is an electric butterfly valve that can be used to lift the equipment. The quality is related to the safety of the equipment and also bears the weight of the equipment. Therefore, the selection of the electric butterfly valve of the suspended butterfly valve is very critical.
Dongfeng suspended butterfly valve electric butterfly valve is processed by stamping, combined with composite 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 butterfly valve electric butterfly valve is 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
The electric butterfly valve of damping butterfly valve is a damping controllable structure that works depending on the rheological characteristics of the magnetorheological fluid itself. The output of the electric butterfly valve of damping mainly depends on the performance of the magnetorheological fluid, the size of the electric butterfly valve of damping and the type of the electric butterfly valve of damping. The flow form and stress state of MR fluid are different, so the working mode of MR damper electric 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 electric butterfly valve, electric butterfly valve, etc.
(2) Cut Mode
The principle of shear mode magnetorheological damping electric 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 electric butterfly valve.
(3) Extrusion mode
