Abstract
The utility model relates to a jacket type nonmetal expansion joint, and belongs to the technical field of fluid transportation pipelines. The expansion joint comprises frames at the two ends, and ring belts connected between the frames at the two ends. The frames are composed of rings with the inner ends and the outer ends extending out of inner vertical plates and outer vertical plates respectively in the radial direction, and the sections of the frames are of L shapes. The inner vertical plates of the frames at the two ends are fixedly connected with the two ends of the inner ring belt through pressing plates respectively, and the outer vertical plates of the frames at the two ends are fixedly connected with the two ends of the outer ring belt through pressing plates respectively. An isolation cavity is formed between the inner ring belt and the outer ring belt, and the outer vertical plates are provided with connection pipe mouths communicated with the isolation cavity. Safety can be guaranteed through dual sealing and sealing performance which can be monitored, and the expansion joint is suitable for transporting dangerous media such as inflammable media, explosive media, poisonous media and harmful media.
Description
Technical field
The utility model relates to a kind of non-metal expansion joint, and especially a kind of jacketed type non-metal expansion joint, belongs to technical field of fluid transportation pipelines.
Background technique
According to the applicant understood, existing non-metal expansion joint adopts wall scroll astragal element by way of compensation, in running, when astragal body or sealed at both ends generation leakage, expansion joint interior media can directly leak in external environment condition, and cannot be monitored at short notice, therefore can not be used for carrying the harmfulness media such as inflammable, explosive, poisonous, harmful.
Summary of the invention
The purpose of this utility model is: the problem existing for above-mentioned prior art, proposes a kind of jacketed type non-metal expansion joint reliable and can monitoring leakage that seals.
In order to reach above object, jacketed type non-metal expansion joint of the present utility model comprises the framework at two ends and is connected to the astragal between the framework of two ends, it is characterized in that: the ring that described framework radially extends respectively inner vertical plate and outer vertical plate by interior outer end forms, its cross section is L-shaped, between the inner vertical plate of described two ends framework, by the two ends of inner clip plate and internal layer astragal, be connected respectively, between the outer vertical plate of described two ends framework, by the two ends of outer plate and outer astragal, be connected respectively, between described internal layer astragal and outer astragal, form separate cavities, described outer vertical plate is provided with the ozzle that is connected being communicated with separate cavities.
In work, the connection ozzle of expansion joint one end frame is connected with detector, and the connection ozzle of the other end framework is connected with spacer medium pipeline, and spacer medium pressure is greater than fed sheet of a media pressure.When expansion joint internal layer astragal or astragal and frame seal face appearance leakage, because delivered inside pressure medium is less than spacer medium pressure, therefore fed sheet of a media can not leak, and spacer medium in rush down make separate cavities pressure change, thereby by detector, find out rear system alarm.
Therefore, the utility model can be monitored and can guarantee safety by double seal and sealing, is suitable for carrying the harmfulness media such as inflammable, explosive, poisonous, harmful.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is an embodiment's of the utility model structural representation.
Embodiment
Embodiment one
The jacketed type non-metal expansion joint of the present embodiment as shown in Figure 1, mainly consists of the framework 1 at two ends and the nonmetal astragal 2,3 being connected between the framework of two ends.The ring that framework 1 radially extends respectively inner vertical plate and outer vertical plate by inside and outside end forms, and its cross section is L-shaped.Between the inner vertical plate of two ends framework 1, the inner clip plate 4 by ring-type is connected by fastening piece 6 with the two ends of internal layer astragal 3 respectively, and between the outer vertical plate of two ends framework, the outer plate 5 by ring-type is connected by fastening piece 6 with the two ends of outer astragal 2 respectively.Between internal layer astragal 3 and outer astragal 2, formed airtight separate cavities, the outer vertical plate of two ends framework 1 is respectively equipped with separate cavities is communicated with and is connected ozzle 7.One of connection ozzle is wherein connected with detector, and another is connected with spacer medium pipeline.
During work, in separate cavities, pass into the spacer medium that pressure is greater than fed sheet of a media.When leaking appears in internal layer astragal 3 or itself and framework 1 sealing surface, because fed sheet of a media pressure is less than spacer medium pressure, therefore can not leak, but this thing spacer medium can in rush down, the pressure of separate cavities will decline, and after being predicted, cause system alarm by detector.When leaking appears in the sealing surface of outer astragal 2 or itself and framework 1, spacer medium can outer rush down, and the pressure of separate cavities also can change, and also can cause system alarm after detector predicts.
As can be seen here, the non-metal expansion joint of the present embodiment has the double seal effect by spacer medium isolation, reliably avoid fed sheet of a media to leak, guarantee safety, and when leaking appears in spacer medium, can monitor and learn in time, send warning message, thereby for carrying the harmfulness medium such as inflammable, explosive, poisonous, harmful to create condition.
Claims (3)
1. a jacketed type non-metal expansion joint, comprise the framework at two ends and be connected to the astragal between the framework of two ends, it is characterized in that: the ring that described framework radially extends respectively inner vertical plate and outer vertical plate by interior outer end forms, its cross section is L-shaped, between the inner vertical plate of described two ends framework, by the two ends of inner clip plate and internal layer astragal, be connected respectively, between the outer vertical plate of described two ends framework, by the two ends of outer plate and outer astragal, be connected respectively, between described internal layer astragal and outer astragal, form separate cavities, described outer vertical plate is provided with the ozzle that is connected being communicated with separate cavities.
2. jacketed type non-metal expansion joint according to claim 1, is characterized in that: the connection ozzle of the end frame in the framework of described two ends is connected with detector, and the connection ozzle of the other end framework is connected with spacer medium pipeline.
3. jacketed type non-metal expansion joint according to claim 1 and 2, is characterized in that: in described separate cavities, pass into the spacer medium that pressure is greater than fed sheet of a media.
