Abstract
The utility model relates to a full corrugated section annular corrugation corrugated pipe which is made of stainless steel materials. A pipe body is in an annular corrugation shape; convex body pipe edges are arranged at both ends of the corrugated pipe body; screw nuts are connected on the corrugated pipe body through the convex pipe body edges; gaskets are arranged on the upper ends of the convex pipe edges in the screw nuts; positions of both ends of the corrugated pipe body which are connected with the screw nuts are not provided with straight sections, and are fully covered by annular corrugations; and the distance from the outer side of the last corrugation of the pipe body end to the bottom of the screw nuts is between 3 and 8 mm. When the corrugated pipe is connected and installed with other rigid pipelines in a state that the root of the corrugated pipe is bended, because the root near the screw nuts does not have the straight sections, the root of the pipe body is fully covered by the annular corrugations, and the phenomenon of permanent bending or depression can be avoided when the root is bended. In addition, the sealing during the connection of the convex pipe body edges, the gaskets and the fixed screw nuts with other pipelines is tight, and the phenomenon of fluid leakage does not occur. The utility model has the advantages of simple structure, good integral bending effect, wide installation positions and long service life.
Description
Technical field
The utility model relates to a kind of full bellows segment circumferential wave bellows, relates to a kind of circumferential wave bellows that does not have straight section in the joint, two ends specifically, belongs to the metal pipe element field.
Background technique
The circumferential wave bellows generally is to be made by stainless steel material, the main connection part that uses at industrial and mining enterprise, chemical enterprise and other pipeline, and its using scope is very extensive.Existingly have its two ends of circumferential wave bellows of straight section and the junction of nut is that one section length is 30～60 millimeters straight section (not having ripple on the straight section), when needs under bent state during with other hard pipeline connection, body root (straight section position) near nut needs bending, owing to do not have ripple on the straight section, its rigidity is strong, can not bending or sheathed poor, when under unavoidable situation, forcing bending, its straight section position can occur killing curved, the depression situation, so not only can cause the passage of bellows to become narrow or be plugged, influence normally passing through of fluid, and after the bellows bending, the body convex edge at bellows body two ends can not form contacting fully of whole plane with the set screw nut convex edge with pad, the body convex edge that can cause the bellows body two ends like this, pad, set screw nut is not poorly sealed or fixing tight with the joint of other pipeline, thereby causes the fluid leakage phenomenon.
The model utility content
The purpose of this utility model is to provide a kind of full bellows segment circumferential wave bellows in order to address the above problem, this bellows is under the root bending state during with other hard pipeline connection, because its body root near nut does not have straight section, the body root is covered by the circumferential wave ripple fully, so not only can overcoming, it kills curved or depressed phenomenon when bending, and the body convex edge at its bellows body two ends, pad, set screw nut are when being connected with other pipeline, seal tightlyer, the fluid leakage phenomenon can not occur.The utility model is simple in structure, and integrally bending is effective, and the mounting point is extensive, long service life.
In order to achieve the above object, the utility model is realized by following technological means:
A kind of full bellows segment circumferential wave bellows, this bellows is made by stainless steel material, and its body is wave ringwise, is provided with the body convex edge at the bellows body two ends, nut is connected on the bellows body by the body convex edge, and the upper end, body convex edge in nut is provided with pad; Straight section is not established at the position that the bellows body two ends are connected with nut, is covered by the circumferential wave ripple fully, and the outside of last ripple of body end is 3～8 millimeters to the distance between nut 2 bottoms.
When full bellows segment circumferential wave bellows need be under the root bending state during with other hard pipeline connection, situation curved, depression can not appear killing, and, the end of bellows body all becomes 90 ° of vertical angles in the curved interior and the outside with nut, body convex edge in nut and pad can run-off the straights, therefore, body convex edge, pad are that whole plane contacts with the convex edge of nut, have so just improved the sealing effect of connection part.
The beneficial effects of the utility model are:
The joint area sealing of this bellows nut is tight, the fluid leakage phenomenon can not occur.The utility model is simple in structure, and integrally bending is effective, and the mounting point is extensive, long service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing 1 is the cross-sectional view of the full bellows segment circumferential wave of the utility model bellows;
Accompanying drawing 2 is the root of the full bellows segment circumferential wave of the utility model bellows cross-sectional view when being in bent state.
As shown in the figure, the Arabic numerals among the figure are expressed as follows:
1. pad, 2. nut, 3. bellows body, 4. body convex edge.
The utility model is described in further detail below in conjunction with embodiment and Figure of description:
Embodiment
Embodiment
As shown in Figure 1, a kind of full bellows segment circumferential wave bellows, this bellows is made by stainless steel material, its body is wave ringwise, be provided with body convex edge 4 at bellows body 3 two ends, nut 2 is connected on the bellows body 3 by body convex edge 4, and 4 upper ends, body convex edge in nut 2 are provided with pad 1.
As shown in Figure 1, straight section is not established at the position that bellows body 3 two ends are connected with nut 2, is covered by the circumferential wave ripple fully, and the outside of last ripple of body end is 3～8 millimeters to the distance between nut 2 bottoms.
As shown in Figure 2, when full bellows segment circumferential wave bellows need be under the root bending state during with other hard pipeline connection, situation curved, depression can not appear killing, and, the end of bellows body 3 all becomes 90 ° of vertical angles in the curved interior and the outside with nut 2, and body convex edge 4 in nut 2 and pad 1 can run-off the straights, therefore, body convex edge 4, pad 1 are that whole plane contacts with the convex edge of nut 2, have so just improved the sealing effect of connection part.
