Abstract
The utility model relates to a pipeline connecting piece which comprises a rectangular pipeline joint flange and a circular pipeline joint flange deviating from the axis of the rectangular pipeline joint flange. A connecting pipe is arranged between the rectangular pipeline joint flange and the circular pipeline joint flange. The connecting pipe is provided with first side walls extending to the circular pipeline joint flange from the long sides of the rectangular pipeline joint flange, second side walls extending to the circular pipeline joint flange from the short sides of the rectangular pipeline joint flange and arc transitional walls extending to the four corners of the rectangular pipeline joint flange from the circular pipeline joint flange, wherein the arc transitional walls are connected with the first side walls and the second side walls respectively in a sealed mode. According to the pipeline connecting piece of the structure, connection between a rectangular pipeline and a circular pipeline can be achieved conveniently.
Description
Technical field
The utility model relates to pipe joint, specifically refers to a kind of for connecting the link of rectangular duct and circular pipe.
Background technique
Pipeline of the prior art, in the laying of pipeline, only adopts a kind of pipeline of form conventionally, for example, adopt the water pipe of circular pipe, the ventilation duct of employing rectangular duct etc.But in actual application, need sometimes circular pipe and rectangular duct to couple together, due to the pipeline property of there are differences of two kinds of forms, therefore implement comparatively difficulty.
Model utility content
The purpose of this utility model is to overcome the problem of above-mentioned prior art, and a kind of pipe joint is provided, and it can be realized being connected between rectangular duct and circular pipe easily.
The purpose of this utility model is to be achieved through the following technical solutions:
Pipe joint, comprise rectangular duct flange and depart from the circular pipe flange of described rectangular duct flange axis, between described rectangular duct flange and circular pipe flange, be provided with connecting tube, described connecting tube has the first side wall that extends to described circular pipe flange from the long limit of described rectangular duct flange, from the minor face of described rectangular duct flange, extend to the second sidewall of described circular pipe flange, and from described circular pipe flange, extend to the arc-shaped transition wall in four corners of described rectangular duct flange, described arc-shaped transition wall is tightly connected with described the first side wall and the second sidewall respectively.
Further, described the first side wall, described the second sidewall and described circular pipe flange are tightly connected; Described arc-shaped transition wall and described rectangular duct flange are tightly connected.
Pipe joint described in the utility model, comprise rectangular duct flange and depart from the circular pipe flange of described rectangular duct flange axis, between rectangular duct flange and circular pipe flange, be provided with connecting tube, connecting tube has the first side wall that extends to circular pipe flange from the long limit of rectangle pipe interface flange, from the minor face of rectangle pipe interface flange, extend to the second sidewall of circular pipe flange, and from circular pipe interface flange, extend to the arc-shaped transition wall in four corners of rectangular duct flange, arc-shaped transition wall is tightly connected with the first side wall and the second sidewall respectively.The pipe joint of this structure, has realized being connected between rectangular duct and circular pipe easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of pipe joint described in the utility model.
Embodiment
