    SELF-SEALING FLANGE
    TECHNICAL FIELD
    The present invention relates to the field of flange connection, in particular to a self-sealing flange.
    BACKGROUND
    Flanges are used to connect pipeline as a connection device, which is convenient for mounting and demounting; existing flange connections have a good sealing performance, but fluid leakage occurs to the flange joint due to corrosion from fluid in the pipeline and flange aging; if timely repair could not be performed, this may cause resource waste and environmental pollution.
    Chinese patent CN204986119U, filed on 8th October, 2015, discloses a flange connection comprising a flange gasket for high-pressure water pipeline, a short-circuit jumper, a first flange, a second flange, a signal line, a buzzer and a power source; the flange gasket is set between a contact surface of the first flange and the second flange, with the short-circuit jumper embedded in an outer ring of the flange gasket; the signal line is embedded into the surface layer of the first flange and the second flange, and the buzzer which links to the power source is connected with the short-circuit jumper through the signal line.
    The flange structure provided by the above patent can be used to control the buzzer to raise alarm when fluid leakage occurs, so that the fluid leakage can be discovered and repaired by staff in time; in other circumstances, if serviceman could not be present in time, the fluid will keep leaking to pollute the environment, which means a low security level.
    SUMMARY OF THE INVENTION
    To solve above problems in prior art, the present invention provides a flange connection capable of automatically preventing fluid leakage. On the occasion that fluid leakage occurs to the flange and the serviceman cannot arrive at the scene timely, this flange is able to prevent the fluid from continuously leaking and raise an alarm at the same time, which will reduce spillage of the fluid in the pipeline and decrease the danger coefficient.
    In order to achieve the above purpose, the present invention adopts a technical scheme as follows: A self-sealing flange, comprises a flange body, a wire connector, a power source, a short-circuit jumper, a sealing gasket and a signal wire; the flange body comprises an upper flange and a lower flange; the sealing gasket is arranged between contact surfaces of the upper flange and the lower flange, and the short-circuit juniper is embedded in the sealing gasket; the upper flange is provided with an upper step, while the lower flange is provided with a lower step; an electromagnet is fixed to the upper step, and an iron ring, which is allowed to move up and down along a central axis of the flange, is placed on the lower step; a sealing component is attached to an inner ring of the iron ring; the electromagnet is connected to the power source through the wire connector, which is then connected to the short-circuit jumper through the signal wire. A first jumper switch is set in the wire connector. A buzzer with a second jumper switch therein is connected to the power source.
    The electromagnet is formed into annulus.
    The sealing component is formed into a cylinder.
    The power source, the short-circuit jumper, the buzzer and the wire connector are arranged outside the flange.
    The advantages of the present invention are as follows:
    The self-sealing flange provided by the present invention comprises an electromagnet attached to the inner wall of the flange and a sealing component attached to the iron ring; the sealing component moves up and down together with the iron ring in the flange. The flange also includes a power source, a signal wire, a short-circuit jumper, a buzzer and a wire connector. When the fluid in the pipeline leaks, short circuit occurs to the short-circuit jumper so as to switch on the wire connector, and the electromagnet will be activated to attract the iron ring to approach. The sealing component will move together with the iron ring to the connecting portion of the upper flange and the lower flange, in order to prevent the fluid leakage and decrease danger coefficient, and the buzzer will raise an alarm at the same time.

    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
    The present invention will be further described with reference to the accompanying figures:
    Embodiment 1
    Fig. 1 and 2 show a self-sealing flange comprising a flange body, a wire connector 5, a power source 7, a short-circuit jumper 8, a sealing gasket 11 and a signal wire 9; the flange body comprises an upper flange 1 and a lower flange 2; the sealing gasket 11 is arranged between contact surfaces of the upper flange 1 and the lower flange 2, and the short-circuit jumper 8 is embedded in the sealing gasket 11. The upper flange 1 is provided with an upper step, while the lower flange 2 is provided with a lower step. An electromagnet 3 is fixed to the upper step, and an iron ring 4, which is allowed to move up and down along a central axis of the flange, is placed on the lower step. A sealing component 10 is attached to an inner ring of the iron ring 4. The electromagnet 3 is connected to the power source 7 through the wire connector 5, which is then connected to the short-circuit jumper 8 through the signal wire 9.
    The direction of arrows in fig 1 and fig 2 shows the flow direction of the fluid in the pipeline. The electromagnet 3 is a fixing part connected to the power source 7 through the wire connector 5, while the iron ring 4 is a moving part. When the fluid in the pipeline leaks, short circuit occurs to the short-circuit juniper 8 so as to switch on the wire connector 5, and the electromagnet 3 will be activated by the power source 7 to attract the iron ring 4 to approach. The sealing component 10 will move together with the iron ring 4 to realize sealing the flange joint. Thus, when fluid in the pipeline leaks, the flange is able to automatically seal and stop the leaking.
    Embodiment 2
    Fig 1 and 2 show a self-sealing flange comprising a flange body, a wire connector 5, a power source 7, a short-circuit jumper 8, a sealing gasket 11 and a signal wire 9; the flange body comprises an upper flange 1 and a lower flange 2; the sealing gasket 11 is arranged between contact surfaces of the upper flange 1 and the lower flange 2, and the short-circuit juniper 8 is embedded in the sealing gasket 11. The upper flange 1 is provided with an upper step, while the lower flange 2 is provided with a lower step. An electromagnet 3 is fixed onto the upper step, and an iron ring 4, which is allowed to move up and down along center axis of the flange, is placed on the lower step. A sealing component 10 is attached to an inner ring of the iron ring 4. The electromagnet 3 is connected to the power source 7 through the wire connector 5, which is then connected to the short-circuit jumper 8 through the signal wire 9. A first juniper switch is set in the wire connector 5. A buzzer 6 with a second jumper switch therein is connected to the power source 7.
    The direction of arrows in fig 1 and fig 2 shows the flow direction of the fluid in the pipeline. The electromagnet 3 is a fixing part connected to the power source 7 through the wire connector 5, while the iron ring 4 is a moving part.
    When the fluid in the pipeline leaks, short circuit occurs to the short-circuit jumper 8 so as to switch on the wire connector 5, and the electromagnet 3 will be activated by the power source 7 to attract the iron ring 4 to approach. The sealing component 10 will move together with the iron ring 4 to realize sealing the flange joint by the sealing component 10.
    Similarly, when fluid leaks at the flange, short circuit occurs to the short-circuit jumper 8, and the signal wire 9 transfers a signal which in turn switches on the first jumper switch in the wire connector 5 and the second jumper switch in the buzzer 6 at the same time; the electromagnet 3 will be activated to attract the iron ring 4 to approach. The sealing component 10 will move together with the iron ring 4 to the electromagnet 3, and realize sealing the flange joint; meanwhile, the buzzer 6 will raise an alarm. This invention realizes automatic sealing when fluid leaks at the flange; it is also able to prevent the fluid from continuously leaking and raise an alarm simultaneously to inform serviceman.
