Abstract
An adapter flange used for pipeline connection comprises a small-bore pipeline and a large-bore pipeline, and the small-bore pipeline and the large-bore pipeline are connected together through the connecting flanges of the respective ends of the small-bore pipeline and the large-bore pipeline. An inner passage which is gradually reduced to be a small-bore passage from a large-bore passage is arranged in at least one connecting flange. An inner passage which is gradually reduced to be a small-bore passage from a large-bore passage is arranged in the connecting flange connected with the end portion of the small-bore pipeline. An inner passage which is gradually reduced to be a small-bore passage from a large-bore passage can also be arranged in the connecting flange connected with the end portion of the large-bore pipeline. Or, an inner passage which is formed by being gradually changed into a large-bore passage communicated with the large-bore pipeline from a small-bore passage communicated with the small-bore pipeline is arranged in the two connected flanges. According to the adapter flange, production and manufacturing cost is saved, the welding operation is reduced, a lot of potential safety hazards are avoided, and due to the fact that weld joints in a cold box in an inner passage is reduced, the safety of equipment operation is greatly improved.
Description
Technical field
The utility model relates to a kind of adapter flange connected for pipeline, it is mainly used in interconnecting between the chemical plant installations tapered pipeline, belongs to the pipeline coupling flange technical field.
Background technique
Air separation facility ice chest interior conduit all moves under installation, low temperature at normal temperatures, and every one weld seam all will bear larger pipeline shrinkage distortional stress.In ice chest, all docking pipelines all need to carry out 100% radiographic inspection, and welding is had relatively high expectations, and from the analysis of air separation plant accident over the years, also often find, a lot of leakages or pipeline break accident always occur on the weld seam problem of pipeline.Under the prerequisite that guarantees the air separation plant performance, should make great efforts to reduce energy consumption, the cost of reducing investment outlay.Often big or small pipe diameter is different because of the equipment from connected, valve etc. for the ice chest interior conduit, while especially being docked with reducer coupling for the heavy caliber welded pipe, as shown in Figure 1, is easy to form the cross weld seam, causes stress to concentrate, and to equipment, brings potential safety hazard.Narrow space in ice chest, welding job inconvenience, take off sand as occurred that when equipment moves accident also needs to shut down, and wastes a large amount of manpower and financial resources.
The model utility content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of ice chest interior conduit welding capacity that can reduce is provided, and save material, improve Economy, easy to use, install reliably, can greatly improve the adapter flange connected for pipeline of equipment safety in operation.
The purpose of this utility model completes by following technical solution, it comprises that a small-bore pipeline and a large diameter pipeline interconnect by the adpting flange of holding separately, is characterized in that in described at least one adpting flange being provided with the footpath at a gulp passage internal channel that reducing is small-bore passage gradually.
Be provided with a small-bore passage internal channel that reducing is the heavy caliber passage gradually in the adpting flange that described small-bore pipeline end joins.
Be provided with the footpath at a gulp passage internal channel that reducing is small-bore passage gradually in the adpting flange that described large diameter pipeline end joins.
Be provided with the small-bore passage formed internal channel of heavy caliber passage that reducing is the connection large diameter pipeline gradually of a connection small-bore pipeline in described two adpting flanges that are connected together.
The utility model, due to flange inside is designed to the reducing form, makes flange be connected with reducer pipe, in flange inside, realizes reducing, has both met the requirement of pipeline reducing diameter, meets again the characteristic of flange itself, and it is succinct that piping layout more is tending towards.Because reducing reducer pipe, effectively avoid the cross weld seam, reduced weld seam.Welding capacity reduces, and has not only saved manufacturing cost but also can reduce weld job, avoids a lot of potential safety hazards.When the minimizing of ice chest interior conduit weld seam also makes the equipment operation, Security improves greatly.
The accompanying drawing explanation
Fig. 1 is the structural representation in a kind of flange connections road of prior art.
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 2, the utility model comprises that a small-bore pipeline 1 and a large diameter pipeline 5 interconnect by the adpting flange 2,4 of holding separately, are provided with footpath at a gulp passage 6 internal channel 7 that reducing is small-bore passage 8 gradually in described at least one adpting flange.
Structure shown in Fig. 2 is: be provided with small-bore passage 8 internal channel 7 that reducing is heavy caliber passage 6 gradually in the adpting flange 2 that described small-bore pipeline 1 end joins.
Other embodiment of the present utility model can be also: be provided with footpath at a gulp passage 6 internal channel 7 that reducing is small-bore passage 8 gradually in the adpting flange 4 that described large diameter pipeline 5 ends join.
Perhaps, be provided with the small-bore passage 8 formed internal channel 7 of heavy caliber passage 6 that reducing is connection large diameter pipeline 5 gradually of a connection small-bore pipeline 1 in described two adpting flanges that are connected together 2,4.
The utility model in the inside of flange, makes weld seam while connecting reduce, the Security of raising equipment operation the reducer pipe design; It effectively utilizes the flange inner space, and flange inside is designed to the reducing form, in flange inside, realizes reducing; Pipeline and flange directly weld, and no longer use the reducer pipe transition, and pipeline connects and is tending towards succinct;
The utility model reduces independent reducer coupling (reducer pipe), not only saves material but also facilitate installation; Weld seam reduces, and can reduce leakage, risk of breakage that the ice chest interior conduit causes because of weld seam, greatly the Security of raising equipment operation.
