Abstract
The invention discloses a valve controlled heat-preservation vacuum lead-acid storage battery which comprises a battery tank, a battery cover, a safety valve and a heat preservation layer, wherein a liquid filling hole is arranged on the battery cover, a valve rod of the safety valve and a valve sheet of the safety valve are arranged in the liquid filling hole, the battery tank is matched with the battery cover, and the battery tank and the battery cover form a vacuum sealed inner space. The interior of the storage battery is vacuumized so that thermal runaway is avoided, and the heat preservation layer enables the storage battery to be scarcely influenced by the outside temperature. The valve controlled heat-preservation vacuum lead-acid storage battery is large in charge-discharge capacity, good in deep discharge restoring performance, small in self-discharging capacity, free of acid mist or acid liquor overflow during charging and little in water loss, can adapt to fast charging and high-power discharging, and has the advantages of being long in service life, large in storage capacity, efficient, durable, corrosion resistant, free of maintenance and pollution and the like. In addition, stored electric quantity of the storage battery is increased, and electrolyte is not layered.
Description
Technical field
The present invention relates to storage battery, be specifically related to a kind of valve-regulated insulation vacuum lead acid accumulator.
Background technology
Valve controlled sealed lead-acid accumulator in the market is difficult to avoid moisture loss, can't further improve its useful life.Excessive moisture loss meeting causes electrolyte minimizing, valve controlled sealed lead-acid accumulator capacitance loss; Cause that positive and negative pole plate disengages or supply sour quantity not sufficient with barrier film; Cause valve controlled sealed lead-acid accumulator can not put electricity and come, and the storage battery thermal capacitance is reduced greatly, the heat of generation speeds up the battery temp rising; Cause the battery cell case dilatancy or burst, influence safe in utilization.
The reason of valve controlled sealed lead-acid accumulator dehydration has a lot, such as, gas recombination is incomplete; Seal bad or opening pressure of safety valve is provided with lowly excessively; Float charge voltage control is not tight, and positive/negative plate gate etching consumes certain moisture or the like, sometimes because the safety valve fault; A large amount of hydrogen, oxygen can be discharged storage battery, also cause moisture loss in the electrolyte.In addition, temperature drift, opening pressure of safety valve are crossed low and shell adopts oxygen to keep the material of poor performance also can accelerate the storage battery dehydration.Safety valve is the vitals of valve controlled sealed lead-acid accumulator, and present valve controlled sealed lead-acid accumulator is difficult to accomplish safety valve in long-term use opening and closing pressure is uniformity all the time.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art; The present invention provides a kind of valve-regulated insulation vacuum lead acid accumulator; Problems such as electrolyte reduces in the existing storage battery use to avoid to greatest extent, be subject to externally temperature influence, be prone to produce " thermal runaway ", yielding and easy self discharge; Can add liquid to greatest extent, arranged long useful life.
Technical scheme: for realizing above-mentioned purpose; Valve-regulated insulation vacuum lead acid accumulator of the present invention; Comprise battery case, battery cover, safety valve and heat-insulation layer, said battery cover is provided with liquid injection hole, and said safety valve cooperates with the liquid injection hole assembling; Said battery case and battery cover are suitable, and said battery case and battery cover form a vacuum-packed inner space.
As preferably, said safety valve is the umbrella ledge structure, and said safety valve comprises bonnet, valve rod and valve block, and valve rod and valve block are installed in the liquid injection hole, and said valve rod is provided with a blind hole, and said safety valve is processed by soft materials such as rubber.
As preferably, said heat-insulation layer is processed to the hard-foam polyurethane integral foam of 60 degree at 45 degree with density, and said heat-insulation layer wraps up storage battery fully.
Beneficial effect: valve-regulated insulation vacuum lead acid accumulator of the present invention, extract the air of internal out through vacuum equipment, make internal become negative pressure of vacuum; Bonnet adsorbed close liquid injection hole outer wall has greatly improved the opening pressure of safety valve, avoids dehydration; Avoid air outside to get into, storage battery dispatched from the factory in the early stage add liquid to greatest extent under the without leakage prerequisite, avoid rich solution in transportation and use, push open safety valve cause run acid, leak sour; Delay or avoid " thermal runaway ", internal becomes negative pressure of vacuum, and then electrolyte evenly adsorbs on the battery terminal; Stopped concentration stratification problem, but the storage battery any direction is placed; The battery electrode group upper space is a vacuum, and then float charge voltage is just low, analyses the oxygen amount just seldom, and electrolyte has good thermal diffusivity in addition, has stopped thermal runaway, has prolonged float life.
Heat-insulation layer has reduced the influence of ambient temperature to storage battery.Itself produces heat charge in batteries and when discharge, and when ambient temperature is lower than internal temperature, the heat that heat-insulation layer produces internal does not shed, and because of temperature is low electric weight can not the degree of depth be emitted when avoiding battery discharging; When ambient temperature was higher than inner temperature, heat-insulation layer can not get into extraneous temperature, and the moisture of internal can not gasify, and the exhaust, safety valve can not opened, and storage battery can dehydration.The insulation of heat-insulation layer, water resistance have improved the cycle performance and the deep discharge recovery capability of storage battery greatly; Heat-insulation layer makes storage battery keep a normal environment for use temperature, reduces the generation of storage battery self discharge and lead sulfate, has prolonged the useful life of storage battery.
