Abstract
The utility model discloses a no elbow of welding seam, the installation structure comprises an elbow, the elbow includes return bend and joint, the first end of return bend is provided with the interface, connect set up in the second end of return bend, connect including taking over and being fixed in sleeve nut on the taking over, sleeve nut is located take over neighbouring the one end of return bend, connect with return bend structure as an organic whole. Compared with the prior art, the utility model discloses an elbow need not to weld as integrated into one piece, and then need not to test, has improved production efficiency greatly, simple structure, easily realization.
Description
Technical Field
The utility model relates to a tubular product accessory technical field especially relates to an elbow of no welding seam.
Background
The elbow is a commonly used connecting pipe fitting in water heating installation, is used for connecting the corner of a pipeline and is used for changing the direction of the pipeline.
At present, elbows on the market are mostly split structures, the elbows and joints are included, during production, the elbows and the joints are produced respectively, and finally the elbows and the joints are connected in a welding mode. The increase of the test process greatly affects the production efficiency, and thus, the solution is urgently needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to above-mentioned problem, provide a no elbow of welding seam to solve current external screw thread elbow and for dividing the body structure, need test, the problem that production efficiency is low after the production is accomplished.
The utility model aims at realizing through the following technical scheme:
the utility model provides a no elbow of welding seam, includes the elbow, the elbow includes return bend and joint, the first end of return bend is provided with the interface, the joint set up in the second end of return bend, the joint is including taking over and being fixed in sleeve nut on the takeover, sleeve nut is located take over the vicinity the one end of return bend, the joint with return bend structure as an organic whole.
As an optimized scheme of the utility model, the return bend includes first straight section, the straight section of second and is used for connecting first straight section the linkage segment of the straight section of second, first straight section with the straight section of second is mutually perpendicular, the linkage segment is the arc structure.
As a preferred scheme of the utility model, the bore of interface is by keeping away from the one end of return bend is to neighbouring the one end of return bend steadilys decrease in proper order.
As an optimized scheme of the utility model, the takeover is kept away from be provided with the external screw thread on the outer terminal surface of the one end of return bend.
As an optimized proposal of the utility model, knurls are arranged on the external thread.
As an optimal scheme of the utility model, the takeover is kept away from be provided with the internal thread on the one end inner wall of return bend.
As an optimized proposal of the utility model, the elbow is a stainless steel elbow.
The beneficial effects of the utility model are that, compared with the prior art, the utility model discloses an elbow is integrated into one piece, need not the welding, and then need not to test, has improved production efficiency greatly, simple structure, easily realization.

Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings. It is to be understood that the embodiments described herein are merely illustrative of the present invention and are not limiting thereof.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a weldless elbow.
In this embodiment, a no-weld elbow includes elbow 101, elbow 101 includes return bend 1 and joint 2, the first end of return bend 1 is provided with interface 11, joint 2 set up in the second end of return bend 1, joint 2 includes takeover 23 and is fixed in sleeve nut 21 on the takeover 23, sleeve nut 21 is located takeover 23 is close to the one end of return bend 1, joint 2 with return bend 1 is structure as an organic whole.
Specifically, in this embodiment, the bent tube 1 includes a first straight section, a second straight section, and a connecting section for connecting the first straight section and the second straight section, the first straight section is perpendicular to the second straight section, and the connecting section is an arc-shaped structure.
Specifically, in this embodiment, the caliber of the interface 11 decreases from the end far away from the elbow 1 to the end near the elbow 1.
Specifically, in this embodiment, an external thread 22 is provided on an outer end surface of one end of the connection pipe 23, which is far away from the elbow pipe 1, and a knurl is provided on the external thread 22, so that a scratch can be prevented.
It should be noted that although in the present embodiment, the outer end surface of the end of the connecting pipe 23 away from the elbow pipe 1 is provided with the external thread 22, the present invention is not limited thereto, and an internal thread structure may also be adopted, as shown in fig. 2.
Specifically, in this embodiment, the elbow 101 is a stainless steel elbow.
The elbow without the welding seam is integrally formed, welding is not needed, testing is not needed, production efficiency is greatly improved, and the elbow without the welding seam is simple in structure and easy to achieve.
The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims.
