Abstract
The invention discloses a kind of stainless steel connection structures of anticorrosion, including cylindrical the first tube body and the second tube body, the internal diameter of first tube body is greater than the outer diameter of the second tube body and first internal diameter of tube body and the second outer tube diameter are adapted, and second tube body is plugged in first tube body.The reinforced multiple tracks ring that a kind of structure is simple it is an advantage of the invention that it is provided, be quickly and expediently installed, be low in cost, good seal performance, anti-drawing strength are high presses adhered thin-wall stainless steel connection structure.
Description
Technical field
The technology of the present invention is related to thin-wall stainless steel interconnection technique field, specifically discloses a kind of anticorrosion stainless steel connection knot
Structure.
Background technique
Common stainless steel thin-wall tube is connected with argon arc welding mode at present: thin-wall stainless steel and weld are formed one
Sealing, construction influenced by field condition, construction bother.Card pressure mode: by stainless-steel thin-wall pipe and with the connector of sealing ring
Connection is formed and is tightly connected.Since sealing performance declines over time for sealing ring weatherability and elastic recoil, leakproofness drop
It is low.There are also using simple crimping bonding connection mode, this mode solves sealing problem, but pulling capacity is less desirable,
Bonding strength is not so good as first two, does not have two sides extruding, sealing position air more sealing cavity easy to form when in addition sealing.
Summary of the invention
The object of the present invention is to provide a kind of stainless steel connection structure of anticorrosion, structure is simple, be quickly and expediently installed, at
This cheap, good seal performance, anti-drawing strength are high.
To achieve the goals above, present invention employs technical solutions below: a kind of stainless steel connection structure of anticorrosion,
Including cylindrical the first tube body and the second tube body, the internal diameter of first tube body is greater than the outer diameter of the second tube body and described the
One internal diameter of tube body and the second outer tube diameter are adapted, and second tube body is plugged in first tube body.
Further, the big groove depth is 0.3-5mm, and quantity is 1-6；The little groove depth is 0.15-
4mm, quantity are greater than 1；And the groove spacing is 0.5-50mm.
Further, the shape of the big groove and little groove is arc-shaped or trapezoidal or diamond shape or knife-edge.
Further, first tube body and the second tube body are the thin-wall stainless steel of DN10-DN200 specification.
The beneficial effects of the present invention are: the internal diameter of first tube body of the invention is greater than the internal diameter of the second tube body, in this way can be with
It realizes the quick grafting of the first tube body and the second tube body, and is connect the first tube body with the second tube body by adhesive layer, gluing
Layer realizes that the first tube body is sealed and connect with tube body, and first squeezes intermediate big groove and can increase bonding strength, excludes press section
Position sealant air, fills sealant to two sides completely, increases sealing reliability, and it is intensive to squeeze two sides little groove formation multiple tracks
Ring groove improves axial, radially connected intensity, and squeezes out sealant with big groove and form multiple tracks ring packing, further mentions
The sealing performance and tensile strength of the first tube body and the second tube body are risen, external close up is connected and uses the forms such as circular arc or bevel edge,
Increase port sealing performance.
Detailed description of the invention
Technical solution in order to illustrate the embodiments of the present invention more clearly, below will be to needed in embodiment description
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only the present invention in order to illustrate more clearly of this hair
Bright embodiment or technical solution in the prior art, below will be p- required for describing the embodiments or the prior art attached
Figure is briefly described, for those of ordinary skill in the art, without creative efforts, can be with root
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The stainless steel connection structure of a kind of anticorrosion as shown in Figure 1, including the first cylindrical tube body 3 and the second tube body
1, the internal diameter of first tube body 3 is greater than the outer diameter of the second tube body 1 and 3 internal diameter of the first tube body and 1 outer diameter phase of the second tube body
It adapts to, second tube body 1 is plugged in first tube body 3, and second tube body 1 is provided with 3 junction of the first tube body
Adhesive layer 2.
When first tube body 3 is connect with the second tube body 1, first coated on the outer wall of the second tube body 1 and the inner wall of the first tube body 3
Anaerobic adhesive, anaerobic adhesive will be smeared uniformly, then by 3 grafting of the second tube body 1 and the first tube body, since the internal diameter of the first tube body 3 is big
In the outer diameter of the second tube body 1, anaerobic adhesive can form adhesive layer 2, gluing between 3 inner wall of 1 outer wall of the second tube body and the first tube body
2 anoxic of layer, which solidify rapidly, connect with the second tube body 1 by the first tube body 3 and realizes that the first tube body 3 and 1 junction of the second tube body are close
Envelope is extruded with specific purpose tool in the first tube body 3 and 1 junction middle part of the second tube body after 3 grafting of the second tube body 1 and the first tube body
Then big groove 4 squeezes out multiple little grooves 5 in 4 two sides of big groove.
Wherein, 4 depth of big groove is 0.3-5mm, and quantity is 1-6；5 depth of little groove is 0.15-4mm,
Quantity is greater than 1, and the groove spacing is 0.5-50mm.
The shape of the big groove 4 and little groove 5 is arc-shaped or trapezoidal or diamond shape or knife-edge.
In addition, first tube body 3 and 1 connecting pin of the second tube body close up using arc-shaped or bevel edge squeeze it is close
Envelope, can further promote the sealing performance of the first tube body 3 and the second tube body 1 in this way.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
