Abstract
The invention relates to a pipeline adapting piece structure. The pipeline adapting piece structure comprises a rectangular pipeline connection flange and a round pipeline connection flange coaxial with the rectangular pipeline connection flange, wherein a connection pipe is fixedly connected between the rectangular pipeline connection flange and the round pipeline connection flange and comprises connection boards which are buckled in a sealed mode; the connection boards are provided with first side connection walls formed by necking from the long edge of the rectangular pipeline connection flange to the round pipeline connection flange; the two sides of each first side connection wall are provided with arc transition portions formed by necking from the round pipeline connection flange to four corners of the rectangular pipeline connection flange; the arc transition portions are connected with folding connection portions; the folding connection portions are mutually in butt joint and sewn to form second side connection walls. By means of the pipeline adapting piece structure of the structure, connection between a round pipeline and a rectangular pipeline is conveniently achieved.
Description
Technical field
The present invention relates to a kind of pipeline connecting parts structure, particularly relating to a kind of connecting-piece structure for connecting circular pipe and rectangular duct.
Background technique
Pipeline of the prior art, in the laying of pipeline, only adopts a kind of pipeline of form usually, such as, adopt the water pipe of circular pipe, adopt the ventilation duct etc. of rectangular duct.But in the application of reality, need circular pipe and rectangular duct to couple together sometimes, due to the pipeline property of there are differences of two kinds of forms, therefore implement comparatively difficulty.
Summary of the invention
The object of the invention is to the problem overcoming above-mentioned prior art, provide a kind of pipeline connecting parts structure, it can realize the connection between circular pipe and rectangular duct easily.
The object of the invention is to be realized by following technology square case:
A kind of pipeline connecting parts structure, comprise rectangular duct flange and the circular pipe flange coaxial with described rectangular duct flange, be connected with connecting tube between described rectangular duct flange and described circular pipe flange, described connecting tube comprises the connecting plate that sealing mutually fastens; Described connecting plate has from the long limit of described rectangular duct flange to the first side connecting wall that described circular pipe flange constriction is formed; The both sides of described first side connecting wall have from described circular pipe flange respectively to the curved transition sections that four corner constriction of described rectangular duct flange are formed; Described curved transition sections is connected with doubling joint, and described doubling joint docks mutually sews up formation second side connecting wall.
Further, the opening area of described rectangular duct flange is greater than the area of described circular pipe flange.
Further, the A/F of described rectangular duct flange is identical with the diameter of described circular pipe flange.
A kind of pipeline connecting parts structure of the present invention, comprise rectangular duct flange and the circular pipe flange coaxial with rectangular duct flange, be connected with connecting tube between rectangular duct flange and circular pipe flange, connecting tube comprises the connecting plate that sealing mutually fastens; Connecting plate has from the long limit of rectangle pipe interface flange to the first side connecting wall that circular pipe flange constriction is formed; The both sides of the first side connecting wall have from circular pipe interface flange respectively to the curved transition sections that four corner constriction of rectangular duct flange are formed; Curved transition sections is connected with doubling joint, and doubling joint docks mutually sews up formation second side connecting wall.By the pipeline connecting parts structure of this structure, achieve the connection between circular pipe and rectangular duct easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pipeline connecting parts structure of the present invention;
Fig. 2 is the expansion schematic diagram of connecting plate in Fig. 1;
concrete enforcement square formula
According to drawings and embodiments the present invention is described in further detail below.
As shown in Figure 1 to Figure 2, a kind of pipeline connecting parts structure described in the embodiment of the present invention, comprise rectangular duct flange 1 and the circular pipe flange 2 with rectangular duct flange 1 axis, be connected with connecting tube 3 between rectangular duct flange 1 and circular pipe flange 2, connecting tube 3 comprises the connecting plate 31 that sealing mutually fastens; Connecting plate 31 has from the long limit of rectangle pipe interface flange 1 to the first side connecting wall 31a that circular pipe flange 2 constriction is formed; The both sides of the first side connecting wall 31a have the curved transition sections 31b formed from four corner constriction of circular pipe interface flange 2 to rectangular duct flange 1 respectively; Curved transition sections 31b is connected with doubling joint 31c, and doubling joint 31c mutually docks and sews up formation second side connecting wall.
The opening area of rectangular duct flange 1 is greater than the area of circular pipe flange 2.The A/F of rectangular duct flange 1 is identical with the diameter of circular pipe flange 2.
The foregoing is only and enforcement square formula of the present invention is described; be not limited to the present invention, for a person skilled in the art, within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
