Description
Technical Field
The utility model relates to a lead acid battery adds sour equipment, in particular to lead acid battery's double sealing leak protection filling head.
Background
A lead-acid accumulator is an accumulator whose electrodes are made of lead and its oxide and whose electrolyte is sulfuric acid solution. English: a Lead-acid battery. In a discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in a charged state, the main components of the positive electrode and the negative electrode are lead sulfate. And is divided into vented accumulator and maintenance-free lead-acid battery. The battery mainly comprises a tubular positive plate, a negative plate, electrolyte, a partition board, a battery jar, a battery cover, a pole, an injection cover and the like.
Lead acid battery need add acid when production, but the in-process of adding acid can produce a problem, easy bubble production, influences and adds acid quality, so adopt the evacuation to add acid now mostly, prevent to produce the bubble, but the leakproofness and the stability of the filling head of current acidification equipment are not good, and easy gas leakage after the evacuation influences and adds acid effect. .
Disclosure of Invention
The utility model provides a lead acid battery's double sealing leak protection filling head, the leakproofness of the filling head of having solved among the prior art lead acid battery acidification device is not good with stability, the defect of easy gas leakage behind the evacuation.
The technical scheme of the utility model is realized like this:
a double-sealing leakage-proof filling head of a lead-acid storage battery comprises a sealing pipe sleeve with an opening at the lower end, wherein a sealing gasket is fixed on the inner top surface of the sealing pipe sleeve, a sealing air bag is fixedly connected to the inner side wall of the sealing pipe sleeve, the sealing air bag is connected with an air inlet pipe, and the air inlet pipe is connected with an electromagnetic air inlet valve, an air pressure sensor and an electromagnetic exhaust valve; the middle of the sealing pipe sleeve is connected with a filling pipe head which comprises an outer vacuum pipe, an inner liquid injection pipe is arranged in the middle of the outer vacuum pipe, and a vacuum pumping port is arranged on the outer vacuum pipe.
Further, the sealing pipe sleeve and the outer vacuum pipe are fixed and sealed through welding.
Further, the lower end of the outer vacuum tube is higher than the lower end of the inner liquid injection tube.
Further, the sealing gasket is a fluororubber gasket.
The utility model has the advantages that: the utility model discloses during the use, downstream under outside elevating gear's the drive, seal gasket pushes down lead acid battery's the upper surface that adds sour mouth, plays sealed effect, then sealed gasbag aerifys, and the side parcel lives lead acid battery's the mouth that adds sour, plays double seal's effect, and is sealed effectual, stability and good reliability.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
