Abstract
The utility model relates to a kind of expansion joint with Mobile flange, comprise bellows and be located at the flange at bellows two ends, bellows one end is provided with step, the intermediate portion of bellows is bellows segment, a smooth section is respectively provided with between the bellows segment of bellows and the two ends of bellows, two flanges are divided into fastening flange and loose flange, and fastening flange is fixedly connected with bellows end; Loose flange is located in the smooth section of close step of bellows, and loose flange is flexibly connected with bellows.The beneficial effects of the utility model are: by improving conventional expanded joint, it is made to be optimized for fixed flange one end, one end Mobile flange by the fixed flange in two ends, the basis reaching expansion joint function well solves conventional expanded joint install in assembling and unloading process difficult efficiency low with problem can not be installed etc., for industrial production brings convenience and high-efficiency, save cost.
Description
Technical field
The utility model relates to a kind of expansion joint, particularly relates to a kind of expansion joint with Mobile flange.
Background technique
Metal corrugated pipe expansion joint (abbreviation expansion joint) is that be heated in modern times pipe network and equipment carries out one of critical component of thermal compensation, there is the effect of bit shift compensation, vibration and noise reducing and sealing, be widely used in each industrial fields such as oil, machinery, electric power, heat supply network, boats and ships, building and metallurgy at present.Conventional expanded joint is when carrying out assembly connection with the flange on other equipment, after one end is connected and fixed, because the mounting hole contraposition of the reason the other ends such as design error, foozle and equipment error there will be certain deviation, cause the mounting hole on flange cannot be connected smoothly with the mounting hole on equipment, there is the situations such as installation is difficult or can not install, industrial production is brought inconvenience, even can cause construction delay, cause unnecessary time and property loss.In addition when equipment break down, expansion joint reaches working life or cause expansion joint to damage to need dismounting and change because of other reasons time, conventional expanded joint also there will be flange mounting hole deviations problem, not easily installs.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of expansion joint with Mobile flange, solves the problem that conventional expanded joint is installed, dismounting is inconvenient.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of expansion joint with Mobile flange, comprise bellows and be located at the flange at described bellows two ends, described bellows one end is provided with step, the intermediate portion of described bellows is bellows segment, a smooth section is respectively provided with between the described bellows segment of described bellows and the two ends of described bellows, it is characterized in that, two described flanges are divided into fastening flange and loose flange, and described fastening flange is fixedly connected with described bellows end; Described loose flange is located in the described smooth section of the close described step of described bellows, and described loose flange is flexibly connected with described bellows.
The beneficial effects of the utility model are: by improving conventional expanded joint, it is made to be optimized for fixed flange one end, one end Mobile flange by the fixed flange in two ends, the basis reaching expansion joint function well solves conventional expanded joint install in assembling and unloading process difficult efficiency low with problem can not be installed etc., for industrial production brings convenience and high-efficiency, save cost.
Accompanying drawing explanation
Fig. 1 is partial sectional view of the present utility model;
In figure 1, bellows segment; 2, smooth section; 3, step; 4, loose flange; 5, fastening flange; 6, external pipe; 7, inner tube.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of expansion joint with Mobile flange, comprise bellows and be located at the flange at described bellows two ends, described bellows one end is provided with step 3, the intermediate portion of described bellows is bellows segment 1, is respectively provided with a smooth section 2, it is characterized in that between the described bellows segment 1 of described bellows and the two ends of described bellows, two described flanges are divided into fastening flange 5 and loose flange 4, and described fastening flange 5 is fixedly connected with described bellows end; Described loose flange 4 is located in the described smooth section 2 of close described step 3 of described bellows, and described loose flange 4 is flexibly connected with described bellows.Described bellows is set to inner tube 7 and external pipe 6 is two-layer.Double-layer structure has high elastic limit, tensile strength and fatigue strength, ensures that bellows normally works.The upper end of described inner tube 7 embeds described step 3, and the upper-end surface of described inner tube 7 is concordant with the upper-end surface of described step 3.Described inner tube 7 lower end embeds described fastening flange 5, and the lower end surface of described inner tube 7 is concordant with the lower end surface of described fastening flange 5.The upper end of described external pipe 6 is welded in described step 3 lower end surface, and the lower end surface of described external pipe 6 is welded in the upper-end surface of described fastening flange 5.
Described fastening flange and described bellows end are welded and fixed.
Described bellows adopts Langaloy, iron-nickel alloy or austenitic stainless steel material to make.
Because described loose flange 4 is flexibly connected with described bellows, so described loose flange 4 can freely rotate at described smooth section 2 place and move.During use, described fastening flange 5 is first connected by bolt with the equipment of one end through gasket seal, then described loose flange 4 carries out contraposition through over-rotation and mobile adjustment with the mounting hole of this section of equipment upper flange, adds gasket seal and add bolt-locking connection again after contraposition completes.
The expansion joint that this kind of band Mobile flange connects assemble and dismounting time very convenient and accurate, while well can realize again the function of expansion joint bit shift compensation, vibration and noise reducing and sealing.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
