Abstract
The utility model discloses an amortization bellows relates to tube machine technical field, including the bellows body, the outer tube is established with the axle sleeve in bellows body both ends, connects through the connecting piece between this end of body of bellows outer wall and the outer tube tip inner wall, it has acoustical coating to fill between bellows body outer wall and the outer tube inner wall, it has acoustical coating to connect still to fill between bellows body outer wall and the outer tube inner wall, the utility model discloses an amortization bellows simple structure stabilizes safety, has to fall the noise cancelling effect that makes an uproar, can reduce the noise that the bellows produced at the during operation, and convenient to use has prolonged the life of bellows.
Description
Technical field
The utility model relates to tubing equipment technical field, is specifically related to a kind of noise reduction bellows.
Background technique
Bellows refers to the tubular elastomeric sensing element connected into along folding retractable direction with collapsible wrinkle sheet.Bellows is widely used in instrument and apparatus, and predominant use is the measuring cell as pressure measuring instruments, pressure is converted to displacement or power.Bellows tube wall is thinner, and sensitivity is higher, and measuring range is that tens of handkerchief is to tens of MPa.Its opening end is fixed, and sealed end is in free state, and utilizes auxiliary helical spring or reed to increase elasticity.Extend along tube length direction under the effect of internal pressure during work, make movable end produce the displacement becoming certain relation with pressure.Movable end drives pointer to get final product the size of direct indicated pressure.Bellows usually combines with displacement transducer the pressure transducer forming and export as electricity, is sometimes also used as isolated component.Because the stretching, extension of bellows requires larger volume-variation, therefore its speed of response is lower than Bourdon tube.Bellows is suitable for measuring low pressure.If Chinese application number is that CN104377622A discloses a kind of New corrugated pipe, provide a kind of easy-to-operat and fast cable can be put into a kind of New corrugated pipe of bellows, but the bellows of this technology does not have erasure effect, cost is relatively high.
Model utility content
The purpose of this utility model is to provide a kind of noise reduction bellows, to solve the above-mentioned multinomial defect caused in prior art.
A kind of noise reduction bellows, comprise bellows body, the coaxial sheathed outer sleeve in described bellows body two ends, connected by link between bellows body end outer wall and outer sleeve inner wall of end, be filled with quieter material between described bellows body outer wall and outer sleeve inner wall, be also filled with quieter material between described bellows body outer wall and outer sleeve inner wall and connect.
Preferably, the outer wall of described bellows body is provided with quieter material.
Preferably, described outer sleeve outer wall is also provided with quieter material.
Preferably, described quieter material material is polyester fibre sheet material, and polyester fibre sheet material is provided with sound-absorption hole.
Preferably, described link is section is hollow circular stainless steel metal thin slice.
The utility model has the advantage of: noise reduction bellows structure of the present utility model is simple, stability and safety, the outer wall of bellows body is provided with quieter material, outer sleeve outer wall is also provided with quieter material, the bellows of this structure has good noise-reduction effect, the noise that bellows operationally produces can be reduced, easy to use, extend the working life of bellows.

Wherein: 1-bellows body, 11-bellows body outer wall, 2-outer sleeve, 21-outer sleeve inner wall, 22-link, 3-quieter material, 31-sound-absorption hole.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of noise reduction bellows, comprise bellows body 1, the coaxial sheathed outer sleeve 2 in described bellows body 1 two ends, connected by link 22 between bellows body end outer wall 11 and outer sleeve inner wall of end 21, quieter material 3 is filled with between described bellows body outer wall 11 and outer sleeve inner wall 21, also be filled with quieter material 3 between described bellows body outer wall 11 and outer sleeve inner wall 21 to connect, noise reduction bellows structure of the present utility model is simple, stability and safety, the outer wall of bellows body 1 is provided with quieter material, outer sleeve 2 outer wall is also provided with quieter material 3, the bellows of this structure has good noise-reduction effect, the noise that bellows operationally produces can be reduced, easy to use, extend the working life of bellows.
It should be noted that the outer wall of described bellows body 1 is provided with quieter material, outer sleeve 2 outer wall is also provided with quieter material, the bellows of this structure has good noise-reduction effect.
In addition, described quieter material 3 material is polyester fibre sheet material, and polyester fibre sheet material is provided with sound-absorption hole 31, and the quieter material 3 of this structure has good erasure effect, has saved resource.
Based on above-mentioned, noise reduction bellows structure of the present utility model is simple, stability and safety, the outer wall of bellows body 1 is provided with quieter material, outer sleeve 2 outer wall is also provided with quieter material 3, and the bellows of this structure has good noise-reduction effect, can reduce the noise that bellows operationally produces, easy to use, extend the working life of bellows.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
