Description

Jacket pipe with in press adpting flange
Technical field
The utility model relate to a kind of jacket pipe with in press adpting flange.
Background technique
Jacket flange is mainly used in being connected and fixed two jacket pipes, linkage structure in the past between jacket flange and jacket pipe as shown in Figure 1, the interior pipe of jacket pipe is welded in flange endoporus, outer tube is welded on the end face of flange, welding connection structure in Fig. 1, for the inconvenience be connected between jacket flange with jacket pipe very, is unfavorable for installing.
Vacuum pipe, low-voltage tube, middle pressure pipe and high-voltage tube are also divided into for jacket pipe itself, the requirement that the Pipe installing of different brackets connects is also different, but adopting when welded flange in the past to adopt the welding manner connection in Fig. 1 can cause certain potential safety hazard to the pipeline after connection, especially for middle pressure pipeline, if or adopt the jacket flange in Fig. 1 to connect, obviously not be applicable to present in press jacketed piping.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of middle pressure jacket flange being applicable to middle pressure jacket pipe and using.
The utility model solves the technological scheme that its technical problem adopts: a kind of jacket pipe with in press adpting flange, comprise flange body, the welded connection of evagination is formed in one end of described flange body, one section of connection pipe body is connected at the other end of described flange body, the body connecting end for being connected with jacket pipe is formed in the end of this connection pipe body, described body connecting end comprises inner sleeve connecting end and outer sleeve connecting end, the radial dimension of described inner sleeve connecting end is less than the radial dimension of outer sleeve connecting end, described welded connection, flange body, have between body connecting end and inner sleeve connecting end and communicate, and the flange endoporus be positioned on same shaft axis.
Further, the diameter of described connection pipe body is less than the diameter of welded connection, and the diameter of outer sleeve connecting end is greater than the diameter of connection pipe body, and the diameter of inner sleeve connecting end is less than the diameter of connection pipe body.
Further, described inner sleeve connecting end and outer sleeve connecting end are provided with the cone mouth for welding.
Further, the body connecting end between described outer sleeve connecting end and inner sleeve connecting end is cone structure.
The beneficial effects of the utility model are: be convenient to jacket flange of the present utility model and be connected with middle pressure jacketed piping, and in the process connected, the inner and outer tubes of middle pressure jacket pipe can be made to be welded to connect with the inner sleeve connecting end of jacket flange and outer sleeve connecting end respectively, linkage structure is relatively stable, is applicable to the jacketed piping of middle pressure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the long splice composition between traditional jacket flange and jacket pipe;
Fig. 2 is the structural representation of middle pressure jacket flange;
Fig. 3 is the long splice composition between middle pressure jacket flange and jacket pipe;
Wherein: 1, flange body, 2, welded connection, 3, connection pipe body, 4, body connecting end, 41, inner sleeve connecting end, 42, outer sleeve connecting end, 5, jacket pipe.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 2, a kind of jacket pipe with in press adpting flange, comprise flange body 1, the welded connection 2 of evagination is formed in one end of flange body 1, one section of connection pipe body 3 is connected at the other end of flange body 1, the body connecting end 4 for being connected with jacket pipe 5 is formed in the end of this connection pipe body 3, body connecting end 4 comprises inner sleeve connecting end 41 and outer sleeve connecting end 42, the radial dimension of inner sleeve connecting end 41 is less than the radial dimension of outer sleeve connecting end 42, welded connection 2, flange body 1, have between body connecting end 4 and inner sleeve connecting end 41 and communicate, and the flange endoporus be positioned on same shaft axis.
The diameter of connection pipe body 3 is less than the diameter of welded connection 2, and the diameter of outer sleeve connecting end 42 is greater than the diameter of connection pipe body 3, and the diameter of inner sleeve connecting end 41 is less than the diameter of connection pipe body 3.
Inner sleeve connecting end 41 and outer sleeve connecting end 42 are provided with the cone mouth for welding.Body connecting end 4 between outer sleeve connecting end 42 and inner sleeve connecting end 41 is in cone structure.
As shown in Figure 3, middle pressure jacket flange is in the linkage structure with jacket pipe 5, the inner and outer tubes of jacket pipe 5 are welded to connect with the inner sleeve connecting end 41 of middle pressure jacket flange and outer sleeve connecting end 42 respectively, make that the connection of jacket pipe 5 is more stable, safety, and the phenomenon revealed not easily occurs.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
