Between connected in fixing seal shape, have conductive column in sleeve, there is gap, the both ends point of conductive column between conductive column and the inner wall of sleeve
Not Chuan Guo the cylinder bottom of plunger and sleeve extend, and connect, lead in sealed solid shape between conductive column and plunger and sleeve cylinder bottom
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.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of liquid-seal type nuclear reactor safety shell electrical penetrations, this is electrical
The sealing effect of penetration piece 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:
Liquid-seal type nuclear reactor safety shell electrical penetration of the invention includes sleeve, and the oral area of sleeve is provided with plunger, plunger
It is connect between sleeve in seal shape, has conductive column in sleeve, there is gap, the both ends of conductive column between conductive column and the inner wall of sleeve
The cylinder bottom for being each passed through plunger and sleeve extends, and connects between conductive column and plunger and sleeve cylinder bottom in seal shape.It is special
Point is in the sleeve filled with dielectric, is provided with liquid level mouth in sleeve lateral wall, there is liquidometer in liquid level mouth, liquidometer it is outer
It is connected between wall 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 in the casing of liquid-seal type nuclear reactor safety shell electrical penetration of the invention, in sleeve lateral wall
It is provided with liquid level mouth, 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.This electricity
Gas penetration piece is filled into sleeve using dielectric, due to the characteristic of liquid, dielectric and sleeve and conduction intercolumniation there is no
Gap.To substantially increase sealing effect, the security risk of nuclear leakage is avoided, available to the reactor safety of marine environment
On shell, widened use scope.Moreover, without matching inflated with nitrogen equipment, so that the small volume of entire penetration piece, occupies
Space it is smaller.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of liquid-seal type nuclear reactor safety shell electrical penetration of the invention；
Fig. 2 is the A-A of Fig. 1 to schematic cross-sectional view.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings.
As depicted in figs. 1 and 2, liquid-seal type nuclear reactor safety shell electrical penetration of the invention includes sleeve 1, sleeve 1
Oral area be provided with plunger, connected between plunger and sleeve 1 in seal shape, there is conductive column 4 in sleeve 1, conductive column 4 and sleeve 1
There is gap between inner wall, 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 plunger
It 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 3 on 1 side wall of sleeve,
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
There is gap, there is casing 9 between the opposite end of two support columns 8, connects between the inner wall of casing 9 and the outer wall of two support columns 8 in sealing
