Description

Technical Field

[0001] The utility model relates to the technical field of building shock absorption, in particular to a high-sealing and quick-installation VFD viscous damper. Background Technique

[0002] The quick-installation VFD viscous damper is a high-sealing viscous damper, which is made according to the principle that throttling resistance will be generated when fluid passes through a throttling hole, and is a damper related to the piston movement speed. It is widely used in high-rise buildings, bridges, seismic retrofit of building structures, seismic resistance of industrial pipeline equipment, military industry and other fields.

[0003] Most of the currently common high-sealing quick-installation VFD viscous dampers on the market are similar in overall structure. They take a steel cylinder body as the main body, and the viscous fluid medium is sealed inside the cylinder body through a sealing end cover. A piston rod is inserted on one side of the cylinder body. Both the piston rod and the side of the cylinder body have connecting bodies for connecting to the building wall. When the wall vibrates and is displaced, the piston rod moves, and the pressure difference before and after the piston causes the viscous fluid to pass through the damper hole, thereby generating a damping force and dissipating the vibration energy input from the outside to the structure, so as to achieve the purpose of reducing the structural vibration response. In the actual use process, there are some functional deficiencies and there is a certain room for improvement. For example, during the operation of the damper, once the pressure is too high, the cylinder body will expand and deform, and then the sealing performance will decrease, and the buffering performance will also drop significantly. Minor deformations are difficult to visually detect with the naked eye and need to be checked one by one regularly, which is rather troublesome and does not have the function of monitoring the deformation of the cylinder body.

[0004] Now, a new type of high-sealing quick-installation VFD viscous damper is proposed to solve the above problems. Content of the Utility Model
