Described corrugated tube elastic body is provided with spring and rising limiter, and this rising limiter can effectively be controlled corrugated tube and move in its elastic range.
Described corrugated tube can adopt metal or nonmetallic materials.
Described gas compartment can be selected to fill different compressible fluids according to the application scenario difference, comprises air or nitrogen.
Described gas compartment is filled with pressure and is lower than below the interior material working pressure 0.1～2.0MPa of surge chamber preferred 0.2～1.0MPa.
Described gas filling valve mainly is made up of bonnet, gasket seal, valve body, spool, regulating ring, O-ring seal and spring, can inflate flexibly and exit, and its regulating ring scalable aeration speed effectively avoids overcharging phenomenon.
Described impact damper convey materials enters surge chamber by adapter, along with the pulsation of material, promotes the corrugated tube elastic body and makes stretching motion, changes the material active volume size of surge chamber, has absorbed the energy that causes because of pulse, thereby has played stable effect.
The present invention has utilized the favorable elasticity of metallic bellows and higher temperature tolerance, and this impact damper can be used under high-temperature condition, is provided with aerating device easily in addition, can regulate gaseous tension in the corrugated tube easily, makes impact damper can use the elevated pressures situation.This invention also is provided with spring and at the corrugated tube peripheral hardware limiting plate is arranged in bellows interior, has increased the impact damper resistance to pressure.
Compared with prior art, the present invention has the following advantages:
One, usable range is wide: corrugated tube can carry out selection according to material characteristic, can adopt metal, nonmetallic materials, especially to heat resisting and pressure resisting requirement height, have special occasions such as corrosion particularly suitable.
Two, safe and reliable: gas filling valve and corrugated tube elastic body have all taken into full account safety in utilization in the invention; Gas filling valve can charge and discharge gas flexibly, is provided with double seal, guarantees that gaseous tension changes within the specific limits in the gas compartment; The corrugated tube elastic body is provided with spring and rising limiter, has guaranteed that corrugated tube changes in elastic range, has avoided the flattening that causes because of inside and outside differential pressure and has drawn bad phenomenon.
Three, airtight performance is good: this invention material when parts damages such as corrugated tube does not leak.
Four, maintenance is convenient: the present invention such as corrugated tube lost efficacy and can embody from two tensimeters fast.
