The connecting structure of the stainless steel pipe comprises the stainless steel pipe and the connecting pipe, and is characterized in that the outer wall of the stainless steel pipe is provided with a positioning concave part, the inner wall of the connecting pipe is provided with a corresponding positioning convex part, the connecting pipe and the stainless steel pipe are connected together in a clamping and pressing mode, and the positioning convex part is clamped in the positioning concave part. The connecting structure of the stainless steel pipe changes the stress relation between the two connecting pipelines by arranging the positioning convex part and the positioning concave part, so that the connecting reliability is ensured by pressure and clamping force between the two connecting pipelines, and the connecting reliability and the sealing performance are greatly improved.
Description
Technical Field
The invention belongs to the technical field of stainless steel products, and particularly relates to a connecting structure of stainless steel pipes.
Background
The stainless steel pipe has the advantages of safety, no toxicity, no corrosion, no exudate, no turbidity and no peculiar smell, does not cause secondary pollution to water quality, keeps the water quality pure and sanitary, and is very suitable for water transportation. However, during the installation of the water pipe, a problem of connection of the stainless steel pipe is inevitably encountered. At present, the connection of the stainless steel pipe is realized by sleeving a connecting pipe and the stainless steel pipe together and then clamping and pressing the end part of the connecting pipe by using a special pressing clamp, so that the end parts of the stainless steel pipe and the connecting pipe are simultaneously contracted (the outer part is small and the inner part is large, and the surface forms a hexagon), thereby achieving the connection strength and meeting the sealing requirement. However, the inner wall of the connecting pipe and the outer wall of the stainless steel pipe are fixed relatively by pressure, and in such a fixing mode, when the stainless steel pipe expands with heat or contracts with cold due to weather or water temperature, relative movement between the connecting pipe and the stainless steel pipe is easy to occur, so that the reliability of connection and sealing is affected.
Disclosure of Invention
The invention aims to provide a stainless steel pipe connecting structure with good connection reliability and good sealing performance.
The connecting structure of the stainless steel pipe comprises the stainless steel pipe and the connecting pipe, and is characterized in that the outer wall of the stainless steel pipe is provided with a positioning concave part, the inner wall of the connecting pipe is provided with a corresponding positioning convex part, the connecting pipe and the stainless steel pipe are connected together in a clamping and pressing mode, and the positioning convex part is clamped in the positioning concave part.
Among the above-mentioned connection structure, not only rely on the pressure between the two to realize relatively fixed between nonrust steel pipe and the connecting pipe, but also realize relatively fixed through the joint relation between location convex part and the location concave part, just so improved the reliability of connecting greatly, and then improved the leakproofness. The connecting pipe can be made of stainless steel, the positioning convex part is processed at one end or two end parts of the connecting pipe in advance, and the positioning concave part of the stainless steel pipe can be processed and formed at a construction site, so that the requirements of different pipeline lengths can be met more flexibly.
Furthermore, the positioning concave part and the positioning convex part are both of annular structures, the size of the positioning concave part (the positioning convex part) is greatly increased by the annular structures, the connecting force between the stainless steel pipe and the connecting pipe can be improved, and the distribution of the connecting force can be more balanced, so that the damage caused by stress concentration at the positioning concave part (the positioning convex part) is avoided.
Furthermore, the outer wall of the stainless steel pipe and the inner wall of the connecting pipe are also provided with sealing concave rings corresponding to the positions, and sealing rings are installed at the positions of the sealing concave rings. Through the annular and set up the sealing ring between nonrust steel pipe and connecting pipe, can improve the leakproofness between the two greatly under the prerequisite that does not influence both connection reliability, and the sealing washer is sealed between nonrust steel pipe and connecting pipe, does not expose in the outside air, can reduce the probability of oxidizing to improve life.
The connecting structure of the stainless steel pipe changes the stress relation between the two connecting pipelines by arranging the positioning convex part and the positioning concave part, so that the connecting reliability is ensured by pressure and clamping force between the two connecting pipelines, and the connecting reliability and the sealing performance are greatly improved.

Detailed Description
The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.
Example 1:
this embodiment has provided a connection structure who connects good reliability, the good nonrust steel pipe of leakproofness.
As shown in fig. 1 and 2, the connecting structure of the stainless steel pipe of the present embodiment includes a stainless steel pipe 1 to be connected and a connecting pipe 2 made of stainless steel, wherein two spaced annular positioning concave portions 3 are provided on an outer wall of an end portion of the stainless steel pipe 1, a corresponding annular positioning convex portion 4 is provided on an inner wall of an end portion of the connecting pipe 2, the connecting pipe 2 and the stainless steel pipe 1 are connected together by a clamping and pressing manner, and the positioning convex portion 4 is clamped in the positioning concave portion 3. In addition, the outer wall of the stainless steel pipe 1 and the inner wall of the connecting pipe 2 are also provided with sealing concave rings 5 corresponding in position, the sealing concave rings 5 are arranged between the two annular positioning convex parts 4 (positioning concave parts 3), and sealing rings 6 are arranged at the sealing concave rings 5.
The connecting pipe 2 may be made of stainless steel, and the positioning protrusion 4 is pre-machined at one end or both ends of the connecting pipe, while the positioning recess 3 of the stainless steel pipe 1 may be machined at the construction site, so as to more flexibly meet the requirements of different pipe lengths. Certainly, two sections of stainless steel pipes 1 are connected together, and it is necessary to set positioning protrusions 4 at both ends of the connecting pipe 2, and this embodiment is only directed to how one end of the connecting pipe 2 is connected with the stainless steel pipe 1, and the connection structure and operation at the other end are the same, and are not described here again.
