Abstract
The utility model relates to a kind of jacket pipe low-pressure continuous acting 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 inner sleeve connecting tube and overcoat connecting tube, described inner sleeve connecting tube is arranged in overcoat connecting tube, described welded connection, flange body and inner sleeve connecting tube are respectively arranged with and communicate and the flange endoporus be positioned on same shaft axis, the length of described inner sleeve connecting tube is greater than the length of overcoat connecting tube.Jacket flange of the present utility model is facilitated to 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 jacket flange respectively, and linkage structure is relatively stable, is applicable to the jacketed piping of low pressure.
Description
Technical field
The utility model relates to a kind of jacket pipe low-pressure continuous acting 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 in Fig. 1 to connect, certain potential safety hazard can be caused to the pipeline after connection.
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 jacket pipe low-pressure continuous acting flange.
The utility model solves the technological scheme that its technical problem adopts: a kind of jacket pipe low-pressure continuous acting 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 inner sleeve connecting tube and overcoat connecting tube, described inner sleeve connecting tube is arranged in overcoat connecting tube, described welded connection, flange body and inner sleeve connecting tube have and communicates and the flange endoporus be positioned on same shaft axis, the length of described inner sleeve connecting tube is greater than the length of overcoat connecting tube.
Further, the diameter of described overcoat connecting tube is less than the diameter of welded connection.
Further, the wall thickness of described overcoat connecting tube is less than the wall thickness of inner sleeve connecting tube.
Further, the outboard end of described inner sleeve connecting tube and overcoat connecting tube is formed with the cone mouth for being welded to connect.
The beneficial effects of the utility model are: facilitate jacket flange of the present utility model to be connected with low pressure jacketed piping, and in the process connected, the inner and outer tubes of low pressure jacket pipe can be made to be welded to connect with jacket flange respectively, linkage structure is relatively stable, is applicable to the jacketed piping of low 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 the utility model low pressure jacket flange;
Fig. 3 is long splice composition between low pressure jacket flange and jacket pipe;
Wherein: 1, flange body, 2, welded connection, 3, inner sleeve connecting tube, 4, overcoat connecting tube, 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 low-pressure continuous acting flange, comprise flange body 1, welded connection 2 is formed at one end evagination of flange body 1, the other end of flange body 1 is provided with inner sleeve connecting tube 3 and overcoat connecting tube 4, inner sleeve connecting tube 3 is arranged in overcoat connecting tube 4, and welded connection 2, flange body 1 and inner sleeve connecting tube 3 have and communicates and the flange endoporus be positioned on same shaft axis, the length of inner sleeve connecting tube 3 is greater than the length of overcoat connecting tube 4.Such length differs, and when being connected with jacket pipe 5 road, the interior pipe of jacket pipe 5 can being made first to be connected with the inner sleeve pipe 3 and be welded to connect, then the outer tube of jacket pipe 5 and overcoat connecting tube 4 are being welded to connect, and connects relatively safe and reliable like this.
The diameter of overcoat connecting tube 4 is less than the diameter of welded connection 2.The wall thickness of overcoat connecting tube 4 is less than the wall thickness of inner sleeve connecting tube 3.
The outboard end of inner sleeve connecting tube 3 and overcoat connecting tube 4 is formed with the cone mouth for being welded to connect.Be convenient to be welded to connect by cone mouth.
As shown in Figure 3, long splice composition between the utility model jacket flange and jacket pipe 5, the inner sleeve connecting tube 3 of jacket flange and the interior pipe of jacket pipe 5 are welded to connect, the overcoat connecting tube 4 of jacket flange and the outer tube of jacket pipe 5 are welded to connect, linkage structure is relatively stable, is applicable to jacket pipe 5 road of low pressure.
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.
