Abstract
The utility model provides a fire-retardant explosion-proof relief valve of valve accuse sealed lead acid battery, includes valve body, rubber post, adjusting bolt, filter disc, upper cover plate, is equipped with the fire-retardant explosion-proof piece of taking a plurality of equipartition through-holes in the cavity between filter disc and upper cover plate, and the through-hole is generally 6 ~ 9, and the aperture is phi 1.5 ~ 3 mm. The utility model is used for the valve control sealed lead-acid storage battery, which can effectively control the internal pressure of the battery and realize the sealing of the battery; and the excessive accumulation of hydrogen and oxygen in the safety valve can be prevented, so that flame cannot be generated even when open fire occurs, and the explosion of the battery cannot be caused.
Description
The utility model relates to a kind of sealed lead acid storage battery safety valve, especially for the flame-proof explosion-proof safety valve of valve-control sealed lead acid battery.
Mainly to act on be to be used for controlling inner pressure of battery to used safety valve on the valve-control sealed lead acid battery, reduces separating out of acid mist in the battery, realizes the sealing of battery.Its groundwork principle is the later stage in charging, the amounts of hydrogen that oxygen that produces when galvanic anode and negative electrode produce has little time compound tense more greatly, the interior pressure of battery will raise, when the pressure in the battery is elevated to setting, safety valve is opened automatically, allows unnecessary gas run out of, and this gas comprises hydrogen and oxygen, when this hydrogen and oxygen run into naked light, will send " " sound.Existing safety valve has a cavity between upper cover plate and filter disc, if above-mentioned gas is when burden is big in cavity, meet naked light and not only can send bigger sound, but also can produce flare, this flare will extend to the inside of battery after the regular hour, thereby cause the blast of battery, cause serious consequence.
The purpose of this utility model is to overcome the weak point of existing safety valve, provides a kind of and can control inner pressure of battery, realizes cell sealing, can prevent to cause the Flame Retardant Explosion-Proof Safety Valve for Valve-Regulated Lead-Acid Batteries of battery explosion again.
The technical solution of the utility model is: Flame Retardant Explosion-Proof Safety Valve for Valve-Regulated Lead-Acid Batteries comprises valve body, rubber column, adjusting bolt, filter disc, upper cover plate, and improvements are the flame-proof explosion-proof sheets that are provided with in the cavity between filter disc and upper cover plate with a plurality of through holes.
Through hole on the above-mentioned flame-proof explosion-proof sheet is 6～9, and the aperture is φ 1.5～3mm, and through hole is uniform, and flame-proof explosion-proof sheet thickness is 2～4mm, generally makes with ABS plastic.
Adopt technique scheme,,, can effectively control inner pressure of battery when cell internal pressure is elevated to existing definite value, when safety valve is opened, can influence the smooth discharge of unnecessary gas in the battery owing to have a plurality of through holes on the flame-proof explosion-proof sheet; Simultaneously the flame-proof explosion-proof sheet the burden that has reduced hydrogen, oxygen in the safety valve is set, both made to run into naked light and also can not produce flare, can not cause battery explosion.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structural representation.
The inner chamber of valve body 1 is equipped with rubber column 2 from bottom to up, regulate bolt 3 and filter disc 4, upper cover plate 6 is equipped with in the valve body upper end, is provided with flame-proof explosion-proof sheet 5 in the cavity between filter disc 4 and upper cover plate 6, the through hole 7 that on this sheet 8 equally distributed apertures to be arranged be φ 2mm, sheet is thick to be 3mm.
Claims (3)
1, a kind of Flame Retardant Explosion-Proof Safety Valve for Valve-Regulated Lead-Acid Batteries comprises valve body, rubber column, adjusting bolt, filter disc, upper cover plate, it is characterized in that being provided with in the cavity between filter disc and upper cover plate the flame-proof explosion-proof sheet with a plurality of through holes.
2, by the described safety valve of claim 1, it is characterized in that the through hole on the flame-proof explosion-proof sheet is 6～9, the aperture is φ 1.5～3mm, and through hole is uniform.
3, by the described safety valve of claim 1, it is characterized in that flame-proof explosion-proof sheet thickness is 2～4mm.
