Abstract
The utility model relates to the technical field of flange manufacture, in particular to a flange with a heavy caliber bushing ring, comprising a sealing surface bushing ring, wherein the flange is provided with a through hole in the center, an inner wall bushing ring is inserted in the through hole; the inner wall bushing ring, the flange and the sealing surface busing ring are welded into an integral structure; and the flange is also provided with a leakage hole used for discharging air in a clearance between the bushing ring and the flange, and the flange is made of carbon steel. In the utility model, the main part of the flange is made of carbon steel, and simultaneously, in order to guarantee the decay resistance of the flange, the inner wall bushing ring and the sealing surface bushing ring are made of stainless steel, thus greatly decreasing the cost.
Description
Technical field
The utility model relates to flange manufacturing technology field, especially a kind of heavy caliber lined flange.
Background technique
Flange is flange plate or bead again, is to make pipe and the interconnective part of pipe, and it is connected in pipe end, and perforation on the flange can be worn bolt, and two flanges are close to, and seals with liner between flange.In industrial pipeline, the use that flange connects is very extensive.Flange is owing to have relatively high expectations, and its material all is a stainless steel, and cost is just bigger like this.
The model utility content
The utility model provides a kind of heavy caliber lined flange, becomes to produce too high this technical problem of cost to solve the heavy caliber lined flange.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of heavy caliber lined flange, has the sealing surface grommet, flange center offers a through hole, insert an inwall grommet in the through hole, inwall grommet, flange and the integrally welded structure of sealing surface grommet three, also offer on the flange and be used to discharge that in the space leakage of air hole between grommet and the flange, the material of flange is a carbon steel.
In order to save material, and guarantee the technical order of flange, inwall grommet length slightly is shorter than the height of flange further, inwall grommet one end and grommet welding, and the other end built-up welding is extremely equal with the flange height.
In order to guarantee the rigidity requirement of flange, further: the material of sealing surface grommet and inwall grommet is stainless steel.
Main body flange of the present utility model is made by carbon steel, and simultaneously in order to guarantee the decay resistance of flange, its inwall grommet and grommet are all made by stainless steel, thereby have significantly reduced cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, flange, 2, the inwall grommet, 3, the sealing surface grommet, 4, Leak hole.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of heavy caliber lined flange, has sealing surface grommet 3, flange 1 center offers a through hole, insert an inwall grommet 2 in the through hole, inwall grommet 2, flange 1 and the integrally welded structure of sealing surface grommet 3 threes also offer on the flange 1 and are used to discharge that in the space leakage of air hole 4 between grommet 3 and the flange 1, the material of flange 1 is a carbon steel, and the material of sealing surface grommet 3 and inwall grommet 2 is stainless steel.
In order to save material, and guarantee the technical order of flange, inwall grommet length slightly is shorter than the height of flange further, inwall grommet one end and grommet welding, and the other end built-up welding is extremely equal with the flange height.
Reprocess sealing surface, sealing surface Ra3.2～6.3 behind flange, grommet and the inwall grommet assembly welding.
Do not have crackle and influence the defective of sealing reliability of adjacent two bolts hole of leak hunting aperture span centre, grommet sealing surface.
Flange size is pressed HG20616, and the flange technical requirements is pressed HG20624 " steel pipe flanges technical specifications (inter-American system) " and carried out.
Main body flange of the present utility model is made by carbon steel, and simultaneously in order to guarantee the decay resistance of flange, its inwall grommet and grommet are all made by stainless steel, thereby have significantly reduced cost.
