Description
Technical field
The present invention relates to capacitor areas, are specifically Leak-proof capacitor.
Background technology
Capacitor is common electrical equipment in circuit, will be in capacitor after in capacitor internal, installation is complete
Portion carries out fluid injection, because if electrolyte runs into air and can discharge, first extracts the air in capacitor out before fluid injection,
Electrolyte is noted again, and theoretically fluid injection is best again for capacitor perfect vacuum, but existing technology is unable to reach, and electrolyte will
Injection, since capacitor internal also has certain air before injection, causes capacitor internal until capacitor is full
Pressure is larger, and when priming device leaves liquid injection port, electrolyte, which can overflow, to be come, primarily now quickly will note by worker
The method of liquid mouth capping, electrolyte have certain corrosivity, and capping has certain risk to worker by hand, and is connect with air
Its working performance can also be influenced by touching.
The content of the invention
For the present invention in view of the shortcomings of the prior art, devising Leak-proof capacitor, this capacitor can reduce electrolysis hydrorrhea
Go out, reduce worker's work risk.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：Leak-proof capacitor, bag
The liquid injection hole on filling head and capacitor is included, is provided with polygon cylinder at the top of the filling head, the filling head is circumferentially disposed
There is the first external screw thread, be provided with inside the filling head for liquid injecting pipeline, the liquid injecting pipeline outside both sides and the filling head
The passage of wall connection, is provided with internal thread in the liquid injection hole, plug is provided in the liquid injection hole, is set outside the plug
The second external screw thread is equipped with, the upper part of the plug is provided with polygonal hole, and the polygonal hole coordinates with the polygon cylinder,
With the screw-internal thread fit, the liquid injection hole inside is fixedly installed branch for first external screw thread and second external screw thread
Frame, the internal stent form slideway, and the slideway side is provided with through hole, spring is provided in the slideway.This capacitance
When device needs fluid injection, under the polygonal hole inward turning steering that the polygon cylinder on filling head is inserted on plug, until described
Passage and through hole cooperation and then progress fluid injection, again rotate together with filling head and plug upwards, directly after fluid injection is completed
Cylinder out of polygonal hole is extracted after departing from the internal thread to the first external screw thread and completes fluid injection, in this way capacitance
Electrolyte in device is closed always, and is automatically performed closure, and worker safety improves, and fluid injection better quality.The present invention with
The prior art is compared, and is had the advantages that：It, will be polygon on filling head when this capacitor of the present invention needs fluid injection
Shape cylinder is inserted under the polygonal hole inward turning steering on plug, until the passage coordinates and then noted with the through hole
Liquid again rotates together with filling head and plug upwards after fluid injection is completed, until the first external screw thread departs from the internal thread
Cylinder out of polygonal hole is extracted afterwards and completes fluid injection, the electrolyte in capacitor is closed always in this way, and
And closure is automatically performed, worker safety improves, and fluid injection better quality.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of filling head.
Fig. 2 is filling head and the structure diagram of liquid injection hole cooperation.
Specific embodiment
Below in conjunction with the accompanying drawings with specific embodiment, the present invention is described further.
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1 to Fig. 2,
Leak-proof capacitor, including the liquid injection hole 2 on filling head 1 and capacitor, 1 top of filling head is provided with polygon
Cylinder 11, the filling head 1 are circumferentially provided with the first external screw thread 12, and 1 inside of filling head is liquid injecting pipeline 13,
The liquid injecting pipeline 13 is provided with the passage 14 connected from both sides with 1 outer wall of filling head, is set in the liquid injection hole 2
Internal thread 21 is equipped with, plug 3 is provided in the liquid injection hole 2, the second external screw thread 31 is provided with outside the plug 3,
3 top of plug is provided with polygonal hole 32, and the polygonal hole 32 coordinates with the polygon cylinder 11, described
First external screw thread 12 and second external screw thread 31 coordinate with the internal thread 21, and 2 inside of liquid injection hole is solid
Surely stent 4 is provided with, 4 inside of stent forms slideway 41, and 41 side of slideway is provided with through hole 42, described
Spring 43 is provided in slideway 41, the diameter of the direct and through hole 42 of the spring 43 is identical, the spring 43
It is vanadium iron material, the both sides of the passage 14 tilt, and drain effect is good after passage 14 tilts.
When this capacitor needs fluid injection, the polygon cylinder 11 on filling head 1 is inserted into more on plug 3
Under 32 inward turning of side shape hole turns to, until the passage 14 and the through hole 42 cooperation and then fluid injection is carried out, it is complete in fluid injection
Into afterwards again rotating together with filling head 1 and plug 3 upwards, by cylinder after the first external screw thread departs from the internal thread
11 extract i.e. completion fluid injection out of polygonal hole 32, and the electrolyte in capacitor is closed always in this way, and
Closure is automatically performed, worker safety improves, and fluid injection better quality.
Protection scope of the present invention includes but not limited to embodiment of above, and protection scope of the present invention is with claims
Subject to, any replacement being readily apparent that those skilled in the art that this technology is made, deformation, improvement each fall within the present invention's
Protection domain.
