Abstract
The utility model relates to a safety valve used for a valve controlled lead acid battery. The safety valve is characterized in that a catalytic plug is added in the safety valve. The catalytic plug consists of an acid filtering sheet, a catalytic plug casing and catalyzer, wherein the acid filtering sheet adopts a Teflon sheet with the aperture between 15 and 40 micron, the catalytic plug casing adopts F4-6 plastics, and the catalyzer is composed of palladium (1.5 to 5 percent) and activated carbon (98.5 to 95 percent). Because using the acid filtering sheet, the utility model greatly reduces the probability of sulphuric acid entering the catalytic plug, and ensures the catalyzer not to be poisoned; Because a large amount of heat can be generate during the catalytic reaction, the high temperature resistant catalytic plug casing is selected, thereby ensuring the safety of the device; the catalytic plug adopts the carbon-based palladium, to enable hydrogen and oxygen to make composite reaction, thereby greatly reducing the water loss ratio of the battery, and greatly prolonging the service life of the battery.
Description
Technical field
The utility model relates to a kind of lead acid accumulator safety valve, belongs to the lead acid accumulator field.
Background technology
Along with the raising of people's living standard, environmental protection is rooted in the hearts of the people, and in each application, valve-control sealed lead acid battery is progressively replacing traditional open type lead acid accumulator.Relative open type lead acid accumulator, valve-control sealed lead acid battery has the safety valve control, does not in use have acid mist and overflows, and can not produce harm to people and equipment, and need not to add acid in whole useful life, adds water, promptly so-called " non-maintaining ".But by actual motion in recent years, true really not so, in use for some time, valve-control sealed lead acid battery just can be owing to dehydration, the dry inefficacy.The battery dehydration mainly is that the effusion battery causes owing to water decomposition when charging is hydrogen and oxygen.Someone reduces the influence of this problem by improving inner pressure of battery, obtained certain effect really, but the thing followed is the reduction of battery security.How can be satisfactory address this problem mentioned on people's the schedule.
The utility model content
The purpose of this utility model provides a kind of fail safe valve-regulated lead-acid battery safety valve good, that can effectively reduce the battery dehydration.
The technical solution of the utility model is: the lead acid accumulator safety valve, comprise the Capsule in valve body and the inner chamber thereof, it is characterized in that the below of Capsule is provided with the catalysis bolt in the body cavity, this catalysis bolt is made of catalytic bolt shell that catalyst is housed and the filter acid film that is positioned at catalysis bolt upper port.
Above-mentioned filter acid film aperture is 15 μ m～40 μ m.Catalytic bolt shell body material is high temperature resistant fluoro-containing plastic, and high temperature resistant fluoro-containing plastic is F4-6.Catalyst is the carbon back palladium material of depositing Pd on the activated carbon.
Adopt above technical scheme, the probability that the use of filter acid film makes sulfuric acid enter the catalysis bolt reduces greatly, has guaranteed that catalyst is not poisoned; Owing to when catalytic reaction, can produce a large amount of heat, thereby select resistant to elevated temperatures catalytic bolt shell for use; Catalyst adopts the carbon back palladium, makes hydrogen and oxygen generation recombination reaction, thereby the percentage of water loss of battery is reduced greatly, has effectively prolonged the life-span of battery.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
As figure, safety valve 1 is made up of valve body 2, Capsule 3, catalysis bolt 4, and wherein Capsule 3 is installed in valve body 2 inside, control open and close valve pressure; Catalysis bolt 4 is made up of filter acid film 5, catalytic bolt shell 6 and catalyst 7, wherein filter acid film 5 employing apertures are the polytetrafluoroethylene of 20 μ m, catalytic bolt shell 6 adopts the F4-6 high-temperature resistance plastice, and 7 of catalyst are palladium at high temperature to be deposited on prepared the carbon back palladium that contains palladium 2% on the activated carbon powder.
The utility model safety valve is assembled on the valve-control sealed lead acid battery of 2V300Ah, with the 2.35V/ monomer battery is carried out bulk charge, the time is 6 months, the average fluid loss of 24 batteries only is 26 grams, and be furnished with the battery of common safety valve, under similarity condition, dehydration is up to 80 grams.As seen, New-type safety valve is significant to the inhibitory action of battery dehydration.
