Abstract
The invention relates to a jacket flange which comprises a flange body. The flange body is provided with a flange hole, and one end of the flange hole is provided with an inner sleeve connecting pipe which is connected with the flange body; the jacket flange further comprises an outer sleeve connecting pipe which is arranged outside the inner sleeve connecting pipe in a sleeving mode and connected with the flange body, an annular cavity is formed between the outer sleeve connecting pipe and the inner sleeve connecting pipe, diversion holes are formed in the corresponding two sides of the flange body in the radial direction, and the diversion holes are communicated with the annular cavity. The jacket flange has the advantages that the position is stable during welding, the welding performance is strong, and the leakproofness between the jacket flange and a pipeline is enhanced; meanwhile, the heat radiating area is increased, and the heat-tracing effect is enhanced.
Description
Technical field
The present invention relates to a kind of flange, particularly relate to a kind of jacket flange.
Background technique
Jacket flange is generally used for needs the inner sleeve of heating inner sleeve medium, the pipeline of outer sleeve connects.It comprises flange body, and flange body has a flange hole, one end of flange hole arranges an inner sleeve connecting tube and is connected with flange body.Lead to steam for outer sleeve, the situation that pressure is high, the connection of existing jacket flange and inner sleeve, outer sleeve also exists the shortcoming of welding performance difference, and seal between jacket flange and pipeline finally can be caused to be deteriorated.And cut off the flowing of heat medium in outer sleeve in the joint of outer sleeve and jacket flange, companion's thermal effect has herein been deteriorated, thus affects the temperature requirement of medium in inner sleeve.
Summary of the invention
For above-mentioned shortcoming, the object of the present invention is to provide and a kind ofly can strengthen welding performance, and improve the jacket flange of companion's thermal effect.
Technology contents of the present invention is: a kind of jacket flange, comprise flange body, flange body has a flange hole, one end of flange hole arranges an inner sleeve connecting tube be connected with flange body, also comprise an outer sleeve connecting tube, the outside that described outer sleeve connecting tube is enclosed within inner sleeve connecting tube is connected with flange body, toroidal cavity is formed between outer sleeve connecting tube and inner sleeve connecting tube, be disposed radially pod apertures in the corresponding both sides of flange body, pod apertures is connected with toroidal cavity.
Further improvement of the present invention is that described inner sleeve connecting tube connects pipe range than described outer sleeve.
Of the present invention further improvement again welds an articulating joint at described pod apertures place.
The present invention is compared with prior art advantageously: owing to being provided with inner sleeve connecting tube and outer sleeve connecting tube respectively, so position can be more stable when jacket flange welds with inner sleeve, outer sleeve, welding performance is strong, enhances the seal of jacket flange and pipeline.Companion's thermal effect simultaneously owing to being provided with pod apertures, adds heat diffusion area, so have also been obtained improvement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is use schematic diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of jacket flange, comprise flange body 1, flange body 1 has a flange hole 2, one end of flange hole 2 arranges an inner sleeve connecting tube 3 be connected with flange body 1, also comprise an outer sleeve connecting tube 4, the outside that described outer sleeve connecting tube 4 is enclosed within inner sleeve connecting tube 3 is connected with flange body 1, toroidal cavity 5 is formed between outer sleeve connecting tube 4 and inner sleeve connecting tube 3, be disposed radially pod apertures 6 in the corresponding both sides of flange body 1, pod apertures 6 is connected with toroidal cavity 5.Inner sleeve connecting tube 3 is longer than outer sleeve connecting tube 4.
As shown in Figure 2, an articulating joint 7 is welded at each pod apertures 6 place of jacket flange, two jacket flanges weld with the inner sleeve that will be connected and outer sleeve respectively, two jacket flange fastening pieces 8 after welding are connected, seal at the joint gasket seal 9 of two jacket flanges, the pod apertures 6 of two jacket flange homonymies is communicated with U-shaped bend pipe 10, and is connected and fixed with articulating joint 7.
Claims (3)
1. a jacket flange, comprise flange body, flange body has a flange hole, one end of flange hole arranges an inner sleeve connecting tube be connected with flange body, it is characterized in that: also comprise an outer sleeve connecting tube, the outside that described outer sleeve connecting tube is enclosed within inner sleeve connecting tube is connected with flange body, forms toroidal cavity between outer sleeve connecting tube and inner sleeve connecting tube, be disposed radially pod apertures in the corresponding both sides of flange body, pod apertures is connected with toroidal cavity.
2. jacket flange according to claim 1, is characterized in that inner sleeve connecting tube connects pipe range than outer sleeve.
