Abstract
The invention discloses a kind of double main cylinders of branch cylinder shell, including the spaced apart two branch cylinders of cylinder, the same side bus of cylinder lateral wall upper edge；Branch cylinder is formed by cylinder lateral wall trepanning outward flanging, and arc transition connects at cylinder, branch cylinder intersection；Minimum range L1 >=8t between adjacent branch cylinder flange（T is cylinder wall thickness）；Cylinder both ends are equipped with outer groove.When branch cylinder flange of the present invention adjacent branch cylinder will not be deformed.
Description
Technical field
The present invention relates to high voltage substation field more particularly to a kind of main cylinders of shell.
Background technology
Set on some main cylinders of shell there are two branch cylinder, two branch cylinders in the same side bus arranged for interval of cylinder lateral wall upper edge,
Two branch cylinders are formed by cylinder lateral wall trepanning outward flanging.The major defect of this main cylinder of shell is：Two branch cylinder distances
It is too close, it influences each other in flange, branch cylinder gross distortion may be caused.
Invention content
This is practical in view of the deficiencies of the prior art, proposes one kind to be avoided that when branch cylinder flange stretches and adjacent branch cylinder is made to generate
Double main cylinders of branch cylinder shell of deformation.
The present invention is achieved through the following technical solutions technical goal.
Double main cylinders of branch cylinder shell, including the spaced apart two branch cylinders of cylinder, the same side bus of cylinder lateral wall upper edge；Institute
Stating branch cylinder is formed by cylinder lateral wall trepanning outward flanging, and arc transition connects at cylinder, branch cylinder intersection；Its improvements exists
In：Minimum range L1 >=8t between adjacent branch cylinder flange（T is cylinder wall thickness）.
In above structure, the cylinder both ends are equipped with outer groove.
Compared with prior art, the present invention having the positive effect that：
1. minimum range L1 >=8t between adjacent branch cylinder flange（T is cylinder wall thickness）, make adjacent branch when branch cylinder flange being avoided to stretch
Cylinder is deformed.
2. cylinder both ends are equipped with outer groove, convenient for being cleared up when welding, while when welding wlding close to root.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is Fig. 1 left views.
Fig. 3 is A-A sectional views in Fig. 1.
Specific implementation mode
The invention will be further described below according to attached drawing and in conjunction with the embodiments.
The main cylinder of double branch cylinder shells shown in attached drawing, including cylinder 2, the 2 same side bus of side wall upper edge spaced apart two of cylinder
A branch cylinder 1, branch cylinder 1 are formed by 2 side-wall hole outward flanging of cylinder, and arc transition connects at cylinder 2,1 intersection of branch cylinder, adjacent
Minimum range L1 >=8t between 1 flange of branch cylinder（T is 2 wall thickness of cylinder）, in the present embodiment, 2 wall thickness t of cylinder is 10mm, adjacent branch
Minimum range L1 is 80 mm between 1 flange of cylinder.
2 both ends of cylinder are equipped with outer groove.
Claims (2)
1. a kind of double main cylinders of branch cylinder shell, including cylinder（2）, cylinder（2）Spaced apart two of the same side bus of side wall upper edge
Branch cylinder（1）；The branch cylinder（1）It is by cylinder（2）Side-wall hole outward flanging is formed, cylinder（2）, branch cylinder（1）Circular arc at intersection
Transition connects；It is characterized in that：Adjacent branch cylinder（1）Minimum range L1 >=8t between flange（T is cylinder（2）Wall thickness）.
2. double main cylinders of branch cylinder shell according to claim 1, it is characterised in that：The cylinder（2）Both ends are equipped with outer slope
Mouthful.
