There is connecting terminal on the overhanging end of electric column.Solid sealing material is filled in the sleeve.However, solid sealing material and set
Cylinder and conductive intercolumniation meeting gap, cause sealing effect bad, there are some potential safety problemss, are not available the anti-of marine environment
It answers on heap containment, use scope is small.Moreover, solid sealing material needs covered with inflated with nitrogen equipment to guarantee air-tightness
Nitrogen is filled in pipe, and install pressure gauge carry out air-tightness monitoring, cause the volume of entire penetration piece larger, the space occupied compared with
Greatly.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of liquid-seal type nuclear reactor safety shell electrical penetrations, should
The sealing effect of electrical penetration is good, avoids security risk, and use scope light, small in size, the space occupied is smaller.
To solve the above problems, the following technical schemes are provided:
The liquid-seal type nuclear reactor safety shell electrical penetration of the utility model includes sleeve, and the oral area of sleeve is provided with column
Plug connects between plunger and sleeve in seal shape, has conductive column in sleeve, there is gap between conductive column and the inner wall of sleeve, conductive
The both ends of column are each passed through plunger and the cylinder bottom of sleeve extends, and connect between conductive column and plunger and sleeve cylinder bottom in seal shape
It connects.Its main feature is that being filled with dielectric in the sleeve, it is provided with liquid level mouth in sleeve lateral wall, there is liquidometer, liquid in liquid level mouth
It is connected between the outer wall of position meter and the inner wall of liquid level mouth in seal shape.
Wherein, the plunger includes two support columns, and two support columns are arranged concentrically in sleeve, two support intercolumniations
There is gap, there is casing between the opposite end of two support columns, is in be tightly connected between the inner wall of casing and the outer wall of two support columns, two
There is support plate in the casing of a support intercolumniation, the plate face of support plate and the axis of casing are vertical, between the surrounding and casing of support plate
In sealed connection.There is resigning mouthful in the corresponding support column of the conductive column and support plate, two between support column and support plate
Through there is support tube in relief hole, corresponding that section of conductive column of plunger is located in support tube, and in close between conductive column and support tube
Envelope connection.
That section of sleeve outer diameter between the inner end and sleeve cylinder bottom of the plunger is gradually reduced.
There is evacuation port on the side wall of the sleeve, has exhaust-valve on evacuation port.
The above scheme has the following advantages:
Due to being filled with dielectric, set in the casing of the liquid-seal type nuclear reactor safety shell electrical penetration of the utility model
It is provided with liquid level mouth on cylinder side wall, there is liquidometer in liquid level mouth, is connected between the outer wall of liquidometer and the inner wall of liquid level mouth in seal shape
It connects.This electrical penetration is filled into sleeve using dielectric, due to the characteristic of liquid, dielectric and sleeve and conductive intercolumniation
There is no gaps.To substantially increase sealing effect, the security risk of nuclear leakage is avoided, available to the anti-of marine environment
It answers on heap containment, widened use scope.Moreover, without matching inflated with nitrogen equipment, so that the volume of entire penetration piece
Smaller, the space occupied is smaller.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the liquid-seal type nuclear reactor safety shell electrical penetration of the utility model；
Fig. 2 is the A-A of Fig. 1 to schematic cross-sectional view.
Specific embodiment
The utility model is described in further details below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the liquid-seal type nuclear reactor safety shell electrical penetration of the utility model includes sleeve 1, set
The oral area of cylinder 1 is provided with plunger, connects between plunger and sleeve 1 in seal shape, there is conductive column 4, conductive column 4 and sleeve 1 in sleeve 1
Inner wall between have gap, the both ends of conductive column 4 are each passed through plunger and the cylinder bottom of sleeve 1 extends, and conductive column 4 and column
Plug is connected between 1 bottom of sleeve in seal shape.It is filled with dielectric 7 in the sleeve 1, is provided with liquid level mouth on 1 side wall of sleeve
3, there is liquidometer 2 in liquid level mouth 3, is connected between the outer wall of liquidometer 2 and the inner wall of liquid level mouth 3 in seal shape.
The plunger includes two support columns 8, and two support columns 8 are arranged concentrically in sleeve 1, between two support columns 8
