Either irregular turning, flexible either thermal deformation of extraction duct etc. or it is not easy to do pipe with the occasion of fixed elbow installation
The connection of the connection of road and pipeline or pipeline and equipment uses.And the high pressure resistant effect of reality of metal bellows many at present
Fruit is unsatisfactory, thus is limited in practical applications by more.
Utility model content：
Technical problem to be solved in the utility model is：It provides a kind of simple in structure, easy to install and use and effectively carries
The metal bellows of high high voltage performance.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
A kind of high pressure resistant metal bellows, including tube body, the tube body is equipped with that multiple corrugated to be set as pressure-bearing convex
Edge structure, multiple compression flange structure equidistant arrangements are set on body outer tube wall, and the compression flange structure includes outer
Portion's pressure-bearing wall and internal bearing ring, are hollow pressure-bearing space between the external pressure-bearing wall and inboard wall of tube body, the pressure-bearing
Ring is placed in pressure-bearing space, and the bearing ring includes four metal rings, when four beckets are placed in pressure-bearing space,
Cross section is filled with bullet in the distribution setting of inverted trapezoidal vertex in the gap between the inner wall of the bearing ring and external pressure-bearing wall
Property buffer layer, the elastic cord breaker is wrapped on the outside of becket.
Preferably, it is set as horizontal pressure-bearing top at the top of the external pressure-bearing wall.
Preferably, the pressure-bearing top of the level is set as corrugated, including multiple pressure-bearing cambered surfaces.
Preferably, the inner wall of the external pressure-bearing wall is equipped with the metal bearing plate of ring inner wall setting, the metal pressure-bearing
The cross section of plate is in inverted groove-like structure setting.
Preferably, the bearing ring further includes multiple endless metal belts, multiple endless metal belt ring sets are in four metals
On the outside of ring, four beckets are then connected as to the metal bearing ring of an entirety.
Preferably, the becket is set as double-deck sleeve structure.
Compared with prior art, the usefulness of the utility model is：The high pressure resistant metal bellows overall structure letter
Single, installation makes and easy to use, can effectively improve the bearing capacity of metal bellows, improve high pressure resistant effect, thus has
There is preferable practicability, be suitble to promote and apply.
Description of the drawings：
The utility model is further illustrated below in conjunction with the accompanying drawings：
Fig. 1 is the partial cross-sectional structural diagram of the utility model.
Specific embodiment：
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained without making creative work belong to
The range of the utility model protection：
A kind of high pressure resistant metal bellows as shown in Figure 1, including tube body 1, the tube body is equipped with multiple corrugated
Compression flange structure is set as, multiple compression flange structure equidistant arrangements are set on body outer tube wall, and the pressure-bearing is convex
Edge structure includes external pressure-bearing wall 2 and internal bearing ring, is hollow pressure-bearing between the external pressure-bearing wall 2 and inboard wall of tube body
Space 4, the bearing ring are placed in pressure-bearing space 4, and the bearing ring includes four metal rings 5, and four beckets 5 are put
When in pressure-bearing space, cross section in the distribution setting of inverted trapezoidal vertex, the bearing ring and external pressure-bearing wall inner wall it
Between gap in filled with elastic cord breaker 6, the elastic cord breaker 6 is wrapped on the outside of becket.
In the present embodiment, further to improve pressure-bearing effect, it is set as horizontal at the top of the external pressure-bearing wall
Pressure-bearing top 7, preferably, the pressure-bearing top of the level is set as corrugated, including multiple pressure-bearing cambered surfaces, institute
The effect for improving pressure-bearing effect can be effectively played by stating pressure-bearing cambered surface.
In addition, to further improve high pressure resistant effect, the inner wall of the external pressure-bearing wall is equipped with the metal of ring inner wall setting
Bearing plate 8, the cross section of the metal bearing plate 8 is in inverted groove-like structure setting, and the becket is set as double-deck
Sleeve structure, due to the structure design of bilayer sleeve, not only save material, but also can also effectively mitigate the weight of bulk metal ring
Amount, thus practicability is high.
When in the present embodiment, to avoid pressure-bearing strong pressure, becket generates excessive side to the side wall of external pressure-bearing wall
Pressure and the side wall for destroying external pressure-bearing wall, the bearing ring further include multiple endless metal belts 9, multiple endless metal belt ring sets
On the outside of four beckets, four beckets are then connected as to the metal bearing ring of an entirety.
Thus, in practical applications, when external strong pressure is acted on the tube body of bellows, pass through external pressure-bearing
Wall, metal bearing plate disperse a part of pressure and then remaining pressure are transferred to becket, due to the ladder of four beckets
Shape designs, thus, whole pressure-bearing effect is more preferable, and effectively reduces the lateral pressure generated to side wall, avoids damage to outside and holds
The side wall of wall is pressed, and the elasticity biography filled between it rushes layer and could be provided as elastic silica gel or elastic rubber, effectively improves protection
Effect and elastic buffer effect, thus practicability is high.
Above-mentioned high pressure resistant metal bellows overall structure is simple, installation make and it is easy to use, metal can be effectively improved
The bearing capacity of bellows, improves high pressure resistant effect, and practicability is high.
It is emphasized that：The above is only the preferred embodiment of the present utility model, and not the utility model is appointed
What formal limitation, every any simple modification made according to the technical essence of the utility model to above example, etc.
With variation and modification, in the range of still falling within technical solutions of the utility model.
