Abstract
The utility model provides a kind of for pressing the provision for disengagement of electrical penetration sealing ring in nuclear power station, it is characterized in that, comprise drawing sleeve, the middle part of drawing sleeve has screwed hole, threaded mandrel to be located in screwed hole and to be threaded with screwed hole, and threaded mandrel can move up and down relative to drawing sleeve, and the bottom of drawing sleeve is provided with external screw thread, described external screw thread can be fixedly connected with the internal thread at porcelain vase top, and conductor can be withstood in the bottom of threaded mandrel.The utility model has simple for structure, easy to use, and simple operation, safety, without advantageous feature such as destructivenesses, are applicable to press electrical penetration in nuclear power plant containment shell in production or maintenance maintenance process, has needed to use during the work of dismounting sealing ring.
Description
Technical field
The utility model relates to a kind of plant equipment extracting tool, and particularly a kind of being exclusively used in nuclear power plant containment shell presses electrical penetration conductor sealing ring, withdrawable type provision for disengagement.
Background technology
Electrical penetration plays a part to keep electrical continuity and maintenance containment pressure boundary integrality inside and outside containment in nuclear power station, together form the 3rd road barrier of reactor, prevent radioactive substance from leaking with containment.Therefore electrical penetration is very high to the requirement of sealing.
The mode of extrusion metal sealing ring is adopted to seal between middle pressure electrical penetration conductor and porcelain vase.This sealing means is safe and reliable, has again high temperature resistant, resistance to irradiation, not easily aging advantage, is suitable for very much the sealing of the electrical penetration of nuclear power station.But because this sealing means needs copper sealing ring to be squeezed to Light deformation to fill up the space between porcelain vase and conductor, reach outstanding sealing effectiveness, the copper sealing ring dismounting therefore after distortion is very difficult.Owing to changing and the needs of dismounting parts, dismantle sealing ring and to be absolutely necessary again work, therefore devise this withdrawable type provision for disengagement.The outer end of this provision for disengagement is connected to porcelain vase end, and conductor ends is fixed in inside, by relative movement, is extracted by related for porcelain vase sealing ring from conductor.Compared with the method dismantled again after destroying sealing ring with now conventional use sharp instruments, use this provision for disengagement not only time saving and energy saving, and due to uniform force application, metal o-ring or porcelain vase also can not be made to scratch conductor.
Summary of the invention
The purpose of this utility model is to provide and is a kind ofly exclusively used in nuclear power plant containment shell the withdrawable type provision for disengagement of pressing electrical penetration conductor sealing ring used, this device can after middle pressure electrical penetration has been assembled Simple detachable conductor sealing ring used, can't to conductor, porcelain vase etc. produce destroy.
In order to achieve the above object, the technical solution of the utility model there is provided a kind of for pressing the provision for disengagement of electrical penetration sealing ring in nuclear power station, it is characterized in that, comprise drawing sleeve, the middle part of drawing sleeve has screwed hole, threaded mandrel to be located in screwed hole and to be threaded with screwed hole, threaded mandrel can move up and down relative to drawing sleeve, the bottom of drawing sleeve is provided with external screw thread, described external screw thread can be fixedly connected with the internal thread at porcelain vase top, and conductor can be withstood in the bottom of threaded mandrel.
Preferably, the top of described threaded mandrel connects auxiliary swing handle.
More preferably, described auxiliary swing handle is detachable.
Preferably, the barrel of described drawing sleeve is provided with anti-rotational handle.
More preferably, described anti-rotational handle is collapsible.
The utility model is when dismantling sealing ring, make use of the relation that porcelain vase and sealing ring clamp, conductor is withstood by threaded mandrel, and constantly rotate, make porcelain vase and sealing ring can along with outwards movement together with drawing sleeve, the utility model is compared with the method for existing direct destruction sealing ring, must not use the destructive instrument such as hammer, chisel, singlely easily can complete dismantlement work fast, and due to uniform force application, also metal o-ring and porcelain vase can not be made to scratch conductor, or cause the injuries such as splash, improve job safety coefficient.Be more suitable for using aborning.
Compared with prior art, the utility model has the advantages that:
The utility model can be used for the porcelain vase of middle pressure penetration piece and sealing ring pull-out conductor, the utility model has simple for structure, easy to use, simple operation, safety are without advantageous feature such as destructivenesses, be applicable in nuclear power plant containment shell, press electrical penetration in production or maintenance maintenance process, needed to use during the work of dismounting sealing ring.Compared with the method dismantled again after destroying sealing ring with now conventional use sharp instruments, use this provision for disengagement not only time saving and energy saving, and due to uniform force application, metal o-ring or porcelain vase also can not be made to scratch conductor.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment
As shown in Figure 1, for the provision for disengagement structural representation for pressing electrical penetration sealing ring in nuclear power station, described for pressing the provision for disengagement of electrical penetration sealing ring to comprise drawing sleeve 1 in nuclear power station, the long 400mm of drawing sleeve 1, external diameter 60mm, the bottom of drawing sleeve 1 is provided with the external screw thread 12 of M68, for connecting the internal thread at porcelain vase 5 top, the middle part of drawing sleeve 1 has M24 screwed hole 11, threaded mandrel 3 with M24 screw thread to be located in screwed hole 11 and to be threaded with screwed hole 11, threaded mandrel 3 length 300mm, threaded mandrel 3 can move up and down relative to drawing sleeve 1, described external screw thread 12 can be fixedly connected with the internal thread at porcelain vase 5 top, conductor 6 can be withstood in the bottom of threaded mandrel 3.The top of described threaded mandrel 3 connects dismountable auxiliary swing handle 4, is the work-saving device rotating threaded mandrel 3.Can not install when rotating threaded mandrel 3 and being lighter, when needs larger torque rotates threaded mandrel 3, load onto auxiliary swing handle 4, can easily rotate threaded mandrel 3.The barrel of described drawing sleeve 1 is provided with folding anti-rotational handle 2, length is 200mm, drawing sleeve 1 side is placed in parallel in after collapsible, save space, when rotating threaded mandrel 3, for preventing drawing sleeve 1 from rotating with threaded mandrel 3, just can use by unclamping to be propped with the latch of drawing sleeve 1 junction when needing to use.
