Abstract
The utility model relates to an S-shaped metal multi-layer bellow elastic and flexible part, comprising an S-shaped metal multi-layer bellow pipe 4 and a flange 5. The S-shaped metal multi-layer bellow pipe 4 is composed of circular arc wave peaks 3, circular arc wave troughs 2 and the straight line sections 7 which are arranged on the both ends of the S-shaped metal multi-layer bellow pipe 4. The circular arc wave peaks 3 and the circular arc wave troughs 2 are connected by bevel face wave walls 1. The included angle of the center line of the bevel face wave wall 1 and the wave is the wave root angle alpha of 5 DEG-30 DEG. The both ends of the S-shaped metal multi-layer bellow pipe 4 are meshed with the circular groove of a bearing member, and are welded in skull-melting, and then the skull-melting welding section 6 is formed. Compared with the existing U-shaped bellow elastic part, the utility model has the advantages of high compensation capacity, strong pressure resistance capacity, long service life, low rigidity, high plane stability, and high tensile strength.
Description
The utility model relates to elasticity, the flexible element of bellows, especially a kind of S type metallic multilayer bellows elasticity, flexible element.
The bellows of producing generally is a U-shaped at present.The crest circular arc of this bellows is to connect with parallel lines with the trough circular arc with being connected of ripple wall, wave root angle α is 0 °, intensity is relatively poor, if improve intensity by the thickness that increases single layer board, then cause bellows stiffness bigger, compensation rate is less, in addition, there is short, poor stability of life-span, shortcoming such as voltage endurance capability is lower.
The purpose of this utility model is the elasticity of making at U type bellows, the problem that flexible element exists, and provides that a kind of compensation performance is good, rigidity is low, precision is high, the life-span is long, the S type metallic multilayer bellows elasticity of good stability, flexible element.
The utility model is achieved in that S type metallic multilayer bellows elasticity, flexible element comprise bellows and stressed member.Bellows is a S type metallic multilayer bellows.S type metallic multilayer bellows is that circular arc crest, circular arc trough and the oblique line Duan Bobi that is connected crest and trough constitute by section.The angle of ripple wall and waveform center line is that wave root angle α is 5 °-30 °.S type metallic multilayer bellows two ends are connected with stressed member in the annular groove of Bao Rong on stressed member, constitute bag fusion welding section.
S type metallic multilayer bellows material is a metal, and the stressed member that is connected with S type metallic multilayer bellows two ends is flange or connecting ring.
Compare with existing U type corrugated pipe elastic element, the elasticity of S type metallic multilayer bellows, the advantage of flexible element are:
1. compensation ability improves more than 25%;
2. voltage endurance capability improves more than 1 times;
3. the life-span improves more than the twice;
4. rigidity descends 50%;
5. plane stability,
By former 1.8 times of design working pressure condition parallelism error ± 1mm, the error of perpendicularity ± 0.9mm brings up at 1.96 times of design working pressure condition parallelism error ± 0.17mm, the error of perpendicularity ± 0.14mm.
6. circumferential weld tensile strength reaches more than the 176KN.Accompanying drawing is a tectonic maps of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in drawings, S type metallic multilayer bellows elasticity, flexible element are made of S type metallic multilayer bellows 4 and flange 5.S type metallic multilayer bellows 4 comprises the straightway 7 at crest 3, trough 2, two ends.Crest 3, trough 4 are circular arc.Crest 3 and trough 4 are that the ripple wall 1 of oblique line links to each other by section.The wave root angle α of ripple wall 1 is 5 °-30 °.S type metallic multilayer bellows 4 two ends straightways part is the bag fusion welding with annular groove on the flange 5; the method that this structure realizes is to adopt gas shielded arc welding; with the shielding gas blow, make in the annular groove of metallic material fusing back Bao Rong on flange of welded part corrugated tube end.
Described stressed member can be other stressed members such as flange, connecting ring.
The material of the utility model bellows can be selected stainless steel, copper, aluminium carbon steel, titanium alloy etc. for use.
