Air bag shock absorber is a heavy industrial shock absorber, a pneumatic shock absorber, is the use of pneumatic resistance to shock products Shock absorbers 81417226053 have nonlinear characteristics, and their characteristic lines can be designed into ideal curves according to needs. Air bag shock absorber absorbs high frequency vibration and has good performance of sound insulation. Through the height control valve, the working height of the air spring can be maintained under any load, and the spring can also have different heights under the same load. Therefore, it is conducive to adapt to the requirements of a variety of structures. The structure of the shock absorber is that the piston rod with a piston is inserted into the cylinder, which is filled with oil. The piston has throttle holes so that the oil in the two Spaces separated by the piston can complement each other. Damping is produced when the viscous oil passes through the throttle hole, the smaller the throttle hole, the greater the damping force, the greater the viscosity of the oil, the greater the damping force. If the size of the throttle hole is constant, too much damping will affect the absorption of shock when the shock absorber is working at a high speed. Therefore, a disc spring valve is set at the outlet of the throttle hole. When the pressure increases, the valve is pushed open, the opening of the throttle hole increases, and the damping becomes smaller. Because the piston is two-way movement, so on both sides of the piston are equipped with spring valves, respectively called compression valve and extension valve.
