Description
Technical field the utility model relates to a kind of non-maintaining valve controlled sealed lead-acid accumulator safety valve, belongs to being used for doing reciprocally the directly field of the device of transformation between electric energy and chemical energy.
Background technology is owing to exist water in the electrolyte and produce oxygen and produce the secondary reaction of hydrogen at negative electrode by electrolysis and at anode in battery in the non-maintaining valve controlled sealed lead-acid accumulator, also exist oxygen and hydrogen to be reduced into water, i.e. the compound secondary reaction of hydrogen-oxygen at negative electrode.Though these two secondary reactions can be reached balance in the ideal case, in actual use the reaction speed of last reaction be greater than the back one the reaction reaction speed, overcharge and cross put in more so.So the gas at inside battery in the battery use can constantly gather, thereby air pressure inside is risen.One of effect of safety valve will in time be opened passage exactly and be reduced inner pressure of battery to discharge gas.As this moment valve can not in time open, will cause cell internal pressure constantly to rise, cause the battery bulge, even cause battery explosion.In addition, though aforementioned two reaction reaction speeds can not be reached balance fully, the oxygen that produces from anode finally can both obtain reduction at negative electrode, can reach the balance of inner oxygen cycle.And when the air outside the battery entered, the higher oxygen of content also can be reduced and causes the oxygen cycle balance destroyed at negative electrode in the air, increases extra self-discharge of battery, causes battery storage voltage on the low side.So two of the effect of non-maintaining valve controlled sealed lead-acid accumulator safety valve is when the battery internal gas pressure is lower than a certain value, valve will cut out automatically, makes the outer air of battery not enter in the battery.As seen, the non-maintaining valve controlled sealed lead-acid accumulator safety valve critical component that is non-maintaining valve controlled sealed lead-acid accumulator.Automatic valve opening and when cell internal pressure is reduced to a certain value, close the main function that valve is non-maintaining valve controlled sealed lead-acid accumulator safety valve automatically when cell internal pressure is increased to a certain value.Force value when this drives valve and the force value when closing valve are called out valve and press and close valve and press.The magnitude relationship of these two force value also is related to the height of cell voltage to the quality of non-maintaining valve controlled sealed lead-acid accumulator charge-discharge performance and the length in life-span.And the service behaviour of the safety valve of each battery also is related to the performance and the life-span of whole battery group in the batteries.Press the too high battery that will make to press and bulging in being subject to if wherein drive valve, close valve and pressed and lowly gas is released let out excessive and caused that electrolyte evaporates, battery dries up.Difference between two other pressure will be tried one's best and just can effectively be stoped the electrolyte dehydration for a short time.Other effects of non-maintaining valve controlled sealed lead-acid accumulator safety valve are can avoid hydrogen in the battery and oxygen to meet with outside naked light and set off an explosion in addition.In a word, non-maintaining valve controlled sealed lead-acid accumulator safety valve should possess following function: 1, reduce inner pressure of battery, prevent the blast of battery bulge.2, prevent that the battery outer air from entering in the battery.3, make battery keep certain interior pressure, making that hydrogen-oxygen is compound can successfully carry out.4, prevent the interior unnecessary discharging of hydrogen-oxygen that is produced of battery, dry too early to avoid battery.5, anti-acid mist prevents that promptly the acid mist of electrolyte evaporation generation from discharging outside battery.6, prevent to meet naked light and make the inside ignition.Existing non-maintaining valve controlled sealed lead-acid accumulator safety valve can be divided into plunger type and Capsule formula.Both compare, because problem such as the non-maintaining valve controlled sealed lead-acid accumulator safety valve of plunger type has valve casing and spool is yielding, sensitivity is low, the service behaviour of the non-maintaining valve controlled sealed lead-acid accumulator safety valve of Capsule formula just is better than the former.The hat brim of the Capsule in the original product of the non-maintaining valve controlled sealed lead-acid accumulator safety valve of Capsule formula is straight wall, and the exhaust nozzle on hat brim and the exhaust valve contacts with cylinder and is called face contact Capsule formula.Open and close the long and switching each safety valve of the line of the buckling defectives such as the line consistency is bad of buckling because the non-maintaining valve controlled sealed lead-acid accumulator safety valve of face contact Capsule formula still exists, German sunlight company has developed the non-maintaining valve controlled sealed lead-acid accumulator safety valve of line contact Capsule formula again.The hat brim bead that the non-maintaining valve controlled sealed lead-acid accumulator safety valve of so-called line contact Capsule formula is wherein Capsule hook inwards goes out a thin limit, Capsule is only contacted with the exhaust nozzle cylinder with this loop wire of thin limit, the interference factor of Capsule itself when having reduced the Capsule distortion has shortened opening and closing buckle line consistency of buckle line and the switching that has improved each safety valve.Simultaneously increased by three lips again in cap, when inner pressure of battery raises valve has been opened easily, air pressure is closed again after discharging easily, thereby the sensitivity that has improved safety valve makes the switching pressure difference littler.But, since in this product between Capsule and the valve gap without any coverage, the explosion-proof and the anti-acid mist performance of this non-maintaining valve controlled sealed lead-acid accumulator safety valve have been influenced, check way according to defined in People's Republic of China's communication industry standard " communication " with the non-maintaining valve controlled sealed lead-acid accumulator specification requirement and the method for inspection (YD/T 799-1996), it is done the explosion-proof performance test and prevents the acid mist performance test, all can not pass through.
