The purpose of this utility model promptly is to provide a kind of high temperature resistant, high pressure resistant, aging, life-span length, steady quality (product qualified rate height), is applicable to the reinforced metal vibration damping soft connector of the environment protection type of domestic water.
Above-mentioned purpose of the present utility model is realized by following technological scheme.
A kind of reinforced metal vibration damping soft connector is characterized in that: connect a corrosion-resistant torpescence metal bellows between two flange plate; Be provided with a plurality of lugs on the circumference of this two flange plate symmetrically, lug is provided with a step hole, and the step hole of upper flange makes progress, and the step hole of lower flange is downward, respectively be provided with damping ring and pad in the step hole, a pull-rod device is passed pad and damping ring and will be gone up lower flange and draw solid; Be surrounded by the rubber layer that one deck is filled with the longitude and latitude tyre cord in the outside of bellows.
Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:
Above-mentioned corrosion-resistant torpescence metal bellows is to be corrugated stainless steel tubing.
Above-mentioned corrosion-resistant torpescence metal bellows is to be titanium or titanium alloy corrugated pipe.
The ripple sectional shape of above-mentioned bellows is to be Ω shape or U-shaped.
The a plurality of lugs that are provided with symmetrically on the circumference of two flange plate are for more than 3 or 3.
Damping ring is to be rubber ripple damping ring.
Above-mentioned pull-rod device is to be screw rod, and two ends are held the location with nut collar with upper and lower flange.
Above-mentioned pull-rod device is the pull bar that is provided with nut for two ends, and a bolt passes pad and the damping ring be located in the flange step hole upper and lower flange is held the location.
Also be provided with locking nut on the bolt of pull-rod device.
Advantage of the present utility model is:
Adopt high-strength corrosion-resistant erosion metal bellows, heat resisting and pressure resisting height, aging, life-span length, steady quality (product qualified rate height), be applicable to the domestic water environment protection type; The ripple sectional shape of bellows is to be Ω shape or U-shaped, has flexible preferably; Equally distributed lug and rubber ripple damping ring can further improve intensity and effectiveness in vibration suppression; Be surrounded by the rubber layer that one deck is filled with the longitude and latitude tyre cord in the outside of bellows, make reinforced metal vibration damping soft connector have higher compressive strength.
