The damping butterfly valve has the double advantages of the low frequency of the butterfly valve damper and the large damping of the damper. It separates the advantages of the two points, eliminates the phenomenon of amplitude surge when the butterfly valve damper resonates, and deals with the natural frequency of the damper
High difficulty is an ideal product for active and passive vibration isolation. The ZD damping butterfly valve shock absorber has a wide load range and strong compliance. It can simultaneously produce obvious effects on active vibration isolation, passive vibration isolation and impact vibration isolation. It is a versatile vibration isolation product with multiple functions and is suitable for the working environment of - 20 ° C-80 ° C. It is an ideal vibration reduction product for air conditioners, thermostatic equipment, fans, cooling towers, refrigeration units, compressors, pumps and other airborne equipment.
The suspended tension spring electric butterfly valve is used for lifting equipment and valves. The combined component of the suspended tension spring electric butterfly valve is composed of the steel frame of the electric butterfly valve and the tension spring. The following section will introduce the planning principle of the downward hanging tension spring electric butterfly valve. The criteria for determining the rigidity of the electric butterfly valve: the engine oscillation has six degrees of freedom, including front and rear, left and right, up and down, yaw, pitch and roll (displacement along the X and Z directions and rotation around the three axes).
6 degrees of freedom shall be considered for the placement of elastic support. When the elastic support (damping pad) is placed, the direction of interference force, the center of gravity of equipment and the geometric dimension of elastic support placement shall be considered. When the disturbing force passes through the center of gravity of the equipment and the direction is vertical, as long as the elastic support (damping pad) is placed symmetrically according to the center of gravity, the elastic support is placed with equal force. When the frequency of interference force is greater than the natural frequency of the vibration isolation system composed of equipment and elastic support.
The environment around the equipment has an outstanding vibration isolation effect. When the mass of the supported object is unevenly distributed, and the elastic support cannot be symmetrically distributed according to the center of gravity, the same type of damping pad with different stiffness can be selected, so that the damping pad near the center of gravity has greater stiffness, and the damping pad far from the center of gravity has smaller stiffness, so that the resultant force of each damping pad is the same as the center of gravity of the supported object.
