Abstract
The invention discloses a damping compensator which is arranged on the inlet and outlet of a pump, and comprises an S-shaped corrugated pipe and connecting flanges which are movably sheathed on the straight sections of the two ends of the corrugated pipe; the wave trough of the corrugated pipe is provided with a rubber ring the cross section of which is in a tadpole shape; the connecting flange is in a hollow out structure; the straight section is welded with a V-shaped groove pad to be used as a connection seal element; the S-shaped corrugated pipe is adopted in the damping compensator; and a high-quality rubber ring is inlaid between the wave troughs, thus satisfying the requirements of damping, and preventing the extrusion deformation caused by the too-large deformation of the corrugated pipe; the V-shaped groove pad ensures the sealing quality and simultaneously reduces the energy transmission, thus enhancing the damping effect; and the connecting flange is in a hollow out structure, has the characteristics of simple structure, light weight, saved cost and good damping effect, and is easy to popularize and use.
Description
Technical field
The present invention relates to a kind of shock-absorption device, relate in particular to a kind of damping compensator that pump discharge is used for absorbing vibration and noise that is installed in.
Background technique
As everyone knows, import and export at pump are provided with vibrations and the noise that the damping compensator can reduce pipe-line system, at present, traditional pump is imported and exported the damping compensator and is generally adopted stainless steel ripple compensator or rubber compensator, the axial cross section of stainless steel ripple compensator is a corrugated, has certain amount of deflection, but absorbing vibration, reduce noise, anti-higher pressure and temperature, but owing to make the material of bellows is metallic material, its damping noise reduction effect is not as rubber compensator, and that rubber compensator exists is unhygienic, easily aging, delamination is torn, fatal shortcomings such as high voltage performance difference, so the market of rubber compensator is in atrophing state these years always, difficult quilt is extensively promoted.
Summary of the invention
The object of the present invention is to provide a kind of damping compensator, it has simple in structure, and is in light weight, saves the characteristics of cost and good damping effect.
The objective of the invention is to be achieved through the following technical solutions:
A kind of damping compensator, the adpting flange that it comprises bellows and is arranged at the bellows two ends, the trough of described bellows is equipped with rubber ring, and described adpting flange kink is at the straight section of bellows.
Especially, described straight section is welded with " V " type groove pad as connecting Sealing.
Especially, the described cross section that is arranged at the rubber ring of bellows trough is a tadpole shape.
Especially, the ripple of described bellows is " S " type.
Especially, described adpting flange is a Pierced structure.
Beneficial effect of the present invention is that described damping compensator adopts ripple to be the bellows of " S " type, is bumped into a top-quality rubber circle between each trough, when satisfying the damping requirement, can prevent the extrusion-deformation that bellows causes too greatly because of distortion; The Placement of adpting flange and bellows is for to be welded on the bellows straight flange on the stainless steel V groove pad, and V groove pad can reduce the transmission of energy when guaranteeing airtight quality, strengthen damping effect; Adpting flange is a Pierced structure, and is not only simple in structure, in light weight, saves cost, and good damping effect, easily is used more widely.

Embodiment
Referring to figs. 1 through shown in Figure 4, in present embodiment, a kind of damping compensator, it comprises the bellows 2 of " S " type, the two ends of described bellows 2 are connected with adpting flange 1, described adpting flange 1 adopts Pierced structure, by finite element analysis, main force bearing point is strengthened, a little do not carry out attenuate to stressing, can satisfy the requirement of strength of product, again can weight reduction, save cost.
The trough of described bellows 2 all is equipped with the rubber ring of being made by top-quality rubber 3, the cross section of described rubber ring 3 is a tadpole shape, utilize the energy of the flexible absorbent system vibration of rubber, rubber ring 3 can prevent the extrusion-deformation that bellows 2 causes too greatly because of distortion when satisfying the damping requirement.
Described adpting flange 1 kink is on bellows straight section 4, and described adpting flange 1 is tightly connected by stainless steel V groove pad 7 with bellows straight section 4, described V groove pad 7 is integrally welded with the 4 usefulness argon arc weldings of bellows straight section, V groove pad 7 can reduce the transmission of energy when guaranteeing airtight quality, strengthen damping effect.
Described adpting flange 1 is provided with negative angle groove 11 with the connecting part of rubber ring 3, in addition, be provided with pull bar 8 between the described adpting flange 1, described pull bar 8 is provided with adjusting nut 9 and nut 10, and an end of described pull bar 8 utilizes set screw nut to be fixed on the adpting flange 1 after the damping pad 5 made by stainless steel and Rubber shock-absorbing pad 6 are installed, and described damping pad 5 is arranged at the outside of Rubber shock-absorbing pad 6.
This damping compensator has simple in structure, and is in light weight, and the characteristics of good damping effect can improve the competitiveness of product greatly, easily are used more widely.
