Abstract
The utility model discloses a kind of anti-wear gas leakage bellows, comprise bellows body, described bellows body two ends are provided with end flange, it is characterized in that, the bellows body between described two end flange is also arranged with at least two body flanges; Connected by least two flexible rods between described end flange; Described flexible rod is through described body flange, and described two flexible rods are arranged axisymmetricly about the central shaft of bellows body.This anti-wear gas leakage bellows is reinforced by flexible rod and body flange, and the avoidable partial loop variation caused because of unbalance stress when compressing, has very wide market prospects.
Description
Technical field
The utility model relates to vacuum machine part field, particularly a kind of anti-wear gas leakage bellows.
Background technique
Bellows is the tubular elastomeric sensing element that collapsible wrinkle sheet connects into along folding retractable direction, bellows is according to the difference of user demand and condition, mainly be divided into the materials such as metal, plastics and composite material, wherein metal bellows is welded by several sheet metal usually, displacement can be produced under the effect of the pressure, play the effects such as compensation pipes thermal distortion, damping, absorption pipeline sedimentation and deformation, be widely used in the industries such as petrochemical industry, instrument, space flight, chemical industry, electric power, cement, metallurgy.
But, bellows of the prior art often occurs bending and deformation under pressure, the inwall at place of curving inwardly inevitably will produce with the lifting arm in body and rubs, after repeatedly and long friction, bellows breakage will cause gas leakage, not only cannot continue to use, also can be oxidized because leaking gas to making inner body.
Therefore, how providing a kind of bellows, make it can not occur bending and deformation in compression process, thus avoid gas leakage, is the required technical problem solved in related domain.
Model utility content
The purpose of this utility model is to provide a kind of anti-wear gas leakage bellows, this bellows is when being under pressure compression, body can be avoided to occur bending and deformation, thus prevent from the lifting arm in curved section and body from producing rubbing and break leaking gas, extend the working life of bellows.
For achieving the above object, the utility model provides a kind of wearing and tearing gas leakage bellows, and comprise bellows body, described bellows body two ends are provided with end flange, and the bellows body between described two end flange is also arranged with at least two body flanges; Connected by least two flexible rods between described end flange; Described flexible rod is through described body flange, and described two flexible rods are arranged axisymmetricly about the central shaft of bellows body.
Preferably, the quantity of described body flange is 3.
Preferably, described 3 body flanges are sheathed on the bellows body between described end flange at equal intervals.
Preferably, the thickness of described body flange is less than the thickness of described end flange.
Preferably, the quantity of described flexible rod is 4.
Preferably, described body flange is welded flange.
Preferably, described bellows is corrugated stainless steel tubing.
Anti-wear gas leakage bellows provided by the utility model; body between the end flange at two ends is set up one or more body flange; and end flange is connected by flexible rod; carry out firmly to bellows body portion; when bellows is stressed compression, make body uniform force, thus protection body can not produce bending deflection; the thickness of body flange used is less than the end flange at two ends, while playing firm effect, alleviate body weight.

Embodiment
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, bellows body 3 of the prior art is welded by multiple sheet metal, in organ shape, the upper and lower two ends of body are welded with two end flange 1,2, and bellows body 3 can be connected with miscellaneous part (as pipeline, tube sheet etc.) by end flange 1,2.But this bellows is when compressing easily because unbalance stress produces bending deflection, and the lifting arm of variant part branch and bellows interior rubs, and causes gas leakage.
Please refer to Fig. 2, the utility model is in order to solve the problem, the first-class spacer sleeve of bellows body 3 between two end flange 1,2 is provided with 3 body flange 4-6, end flange 1,2 is connected by two flexible rods 7,8, and flexible rod 7,8 is through body flange 4-6.In bellows compression or recovery process, flexible rod 7,8 is also along with body shortens or extend, flexible rod 7,8 is arranged axisymmetricly about the central shaft (i.e. the card center of end flange 1,2 and body flange 4-6) of bellows body 3, as further improvement, please refer to the plan view of Fig. 3, it is cruciform symmetry that the perpendicular bisector direction of flexible rod 7,8 lines arranges the flexible rod 9 of two positional symmetry, 10(i.e. 4 flexible rod 7-10 again).
The utility model is reinforced three, the upper, middle and lower part of bellows body 3 by body flange 4-6 and flexible rod 7-10 comprehensively, make body when being subject to axial pressure compression, can not occur bending and deformation because local pressure is uneven, thus avoid occurring to rub with the lifting arm of pipe inside and leaking gas.The thickness of body flange 4-6 is less than the thickness of end flange 1,2, while guarantee is reinforced bellows body 3, alleviate body overall weight.
Bellows body 3 is stainless steel body, has good rigidity, not easily deforms, and body flange 4-6 is welded flange, and welding manner simple and fast is economical and practical.
Above-mentioned anti-wear gas leakage bellows is only preferred version of the present utility model, is specifically not limited thereto, and can make pointed adjustment according to actual needs on this basis, thus obtain different mode of executions.Such as, increase according to the length of bellows body 3 or the actual operation requirements quantity to body flange and flexible rod or reduce, the spacing changing body flange etc., because mode in the cards is more, illustrate no longer one by one at this.
Above anti-wear gas leakage bellows provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment just understands core concept of the present utility model for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
