Abstract
The invention discloses a connecting elbow with a connecting nut. The connecting elbow comprises a connecting bend and the connecting nut, wherein a first spacing ring is arranged on the connecting nut; the connecting bend comprises a first connecting pipe, a second connecting pipe and a third connecting pipe, a second spacing ring is arranged at one end of the first connecting pipe, and the connecting nut and the first connecting pipe are in turning connection. The connecting elbow with the connecting nut of the invention has the advantages that the connecting bend with three segments of the connecting pipes is arranged, so that the stress in a pipeline can be better reduced, and the drag loss when fluid flows the elbow is smaller; the connecting nut is arranged so that the connecting elbow is convenient and reliable to connect.
Description
Technical field
The present invention relates to a kind of connecting bend, more precisely a kind of connecting bend with attaching nut.
Background technique
Connecting bend is used for connecting two sections of mutual vertically arranged pipelines, but orthogonal two sections of directly vertical connections mutually of connecting bend of the prior art, this Placement is larger at the stress of joint, pipeline has curvedization of length after expanding with heat and contract with cold on its length direction, stress is larger, and the drag losses in this elbow is larger simultaneously.
?
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby provide a kind of bridge piece with being formed by three sections of connecting tubes, can reduce preferably the stress in pipeline, when fluid flows through elbow, drag losses is less, with attaching nut, the reliable connecting bend with attaching nut easy to connect.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of connecting bend with attaching nut, comprise a bridge piece, described connecting bend also comprises an attaching nut, on described attaching nut, be provided with one first limited ring, described bridge piece comprises one first connecting tube, one second connecting tube and one the 3rd connecting tube, one end of the first described connecting tube is provided with one second limited ring, and described attaching nut and described the first connecting tube are rotationally connected.
As preferred embodiment of the present invention, the end of the first described connecting tube is provided with a fastening groove.
As preferred embodiment of the present invention, the first described connecting tube and described the 3rd connecting tube are arranged vertically mutually.
As preferred embodiment of the present invention, on the 3rd described connecting tube, be provided with more than three non-slip process.
The advantage of the connecting bend with attaching nut of the present invention is: with the bridge piece being made up of three sections of connecting tubes, can reduce preferably the stress in pipeline, when fluid flows through elbow, drag losses is less, with attaching nut, easy to connect reliable.

Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The advantage of the connecting bend with attaching nut of the present invention is: with the bridge piece being made up of three sections of connecting tubes, can reduce preferably the stress in pipeline, when fluid flows through elbow, drag losses is less, with attaching nut, easy to connect reliable.
As shown in Figure 1 to Figure 3, a kind of connecting bend with attaching nut, comprise a bridge piece 1, this connecting bend also comprises an attaching nut 2, on this attaching nut 2, be provided with one first limited ring 21, this bridge piece 1 comprises one first connecting tube 11, one second connecting tube 12 and one the 3rd connecting tube 13, and one end of this first connecting tube 11 is provided with one second limited ring 111, and this attaching nut 2 is rotationally connected with this first connecting tube 11.
As shown in Figure 2, Figure 4 shows, the end of this first connecting tube 11 is provided with a fastening groove 112.
As shown in Figure 1 and Figure 2, this first connecting tube 11 is arranged vertically mutually with the 3rd connecting tube 13.
As shown in Figure 2, on the 3rd connecting tube 13, be provided with more than three non-slip process 131.
Below only with a mode of execution, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more function module simultaneously, thereby expands to greatest extent its function.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
