Description

Jacket pipe high pressure joint flange
Technical field
The utility model relates to a kind of jacket pipe high pressure joint 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 high pressure pipe line, if or adopted the jacket flange in Fig. 1 to connect, could potential safety hazard would be there is.
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 high pressure sheath flange.
The utility model solves the technological scheme that its technical problem adopts: a kind of jacket pipe high pressure joint flange, comprise flange body, welded connection is formed at one end evagination of described flange body, the other end of described flange body is provided with jacket pipe connecting end, the overall tapered structure of described jacket pipe connecting end, the bigger diameter end of described jacket pipe connecting end is connected with flange body, the miner diameter end of described jacket pipe connecting end is connected with inner sleeve connecting end and outer sleeve connecting end, the length of described inner sleeve connecting end is greater than the length of outer sleeve connecting end, described welded connection, flange body, have between jacket pipe connecting end and inner sleeve connecting end and communicate, and the flange endoporus be positioned on same shaft axis.
The jacket pipe connecting end of cone structure can improve the join strength of whole flange.
Further, the size of described jacket pipe connecting end bigger diameter end is greater than the size of welded connection.
Further, the wall thickness of described inner sleeve connecting end is greater than the wall thickness of outer sleeve connecting end.
Further, described inner sleeve connecting end and outer sleeve connecting end are formed with the taper weld bond for welding.Taper soldering opening mainly can conveniently weld, and makes welded structure reliable and stable.
The beneficial effects of the utility model are: be convenient to jacket flange of the present utility model and be connected with jacketed piping, and in the process connected, the inner and outer tubes of 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 high 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 high pressure sheath flange;
Fig. 3 is the long splice composition between high pressure sheath flange and jacket pipe;
Wherein: 1, flange body, 2, welded connection, 3, jacket pipe connecting end, 4, inner sleeve connecting end, 5, outer sleeve connecting end, 6, 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 high pressure joint flange, comprise flange body 1, welded connection 2 is formed at one end evagination of flange body 1, the other end of described flange body 1 is provided with jacket pipe connecting end 3, the overall tapered structure of jacket pipe connecting end 3, the bigger diameter end of jacket pipe connecting end 3 is connected with flange body 1, the miner diameter end of jacket pipe connecting end 3 is connected with inner sleeve connecting end 4 and outer sleeve connecting end 5, the length of inner sleeve connecting end 4 is greater than the length of outer sleeve connecting end 5, welded connection 2, flange body 1, have between jacket pipe connecting end 3 and inner sleeve connecting end 4 and communicate, and the flange endoporus be positioned on same shaft axis.
The size of jacket pipe connecting end 3 bigger diameter end is greater than the size of welded connection 2.The wall thickness of inner sleeve connecting end 4 is greater than the wall thickness of outer sleeve connecting end 5.
Inner sleeve connecting end 4 and outer sleeve connecting end 5 are formed with the taper weld bond for welding.Taper soldering opening mainly can conveniently weld, and makes welded structure reliable and stable.
As shown in Figure 3, high pressure sheath flange is in the linkage structure with jacket pipe 6, the inner and outer tubes of jacket pipe 6 are welded to connect with the inner sleeve connecting end 4 of high pressure sheath flange and outer sleeve connecting end 5 respectively, make that the connection of high pressure sheath pipe 6 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.
