Abstract

A valve control hydrogen elimination safety valve is used for sealed batteries, the bottom end of a valve body is provided with a hydrogen elimination room filled with palladium catalyst, a through hole of the valve body arranged on the top of the hydrogen elimination room is provided with an explosion rupture disc, a ring-shape boss stretches towards the upper port of the valve body along an axial direction in the through hole arranged in the center of the valve body, a lip valve is sleeved on the ring-shape boss, an explosion rupture disc is clipped in the through hole arranged in the center of the valve body on the upper end of the lip valve through two tablet formings, the upper port of the valve body is provided with a plastic cap. The utility model has reasonable structure and convenient use, the pressure difference of opening and closing the valve is small, thus effectively reducing the water loss inside a battery and being applicable to being used together with current sealing and maintenance-free batteries.

Description

Valve controlling sealed lead accumulator hydrogen-removing safety valve
Technical field
The utility model relates to a kind of valve controlling sealed lead accumulator safety valve, and refering in particular to is a kind of valve controlling sealed lead accumulator hydrogen-removing safety valve.
Background technology
The safety valve of traditional valve controlling sealed lead accumulator has the extraneous gas of preventing and enters inside battery; When battery charge, provide certain interior pressure, to promote the ability of negative pole absorption oxygen in the battery; Prevent that battery from producing functions such as blast.But because the problem that its structural design exists, in the use, part still comes with some shortcomings: at first cylindrical or hat safety valve pressure temperature influence is very big, and the pressure differential of open and close valve is bigger.This has on the one hand proposed harsh requirement to the operating ambient temperature of battery, and on the other hand, inner pressure of battery changes greatly, causes the instability of battery performance; Secondly, can not reach 100% because battery cathode absorbs the efficient of oxygen, therefore the hydrogen that produces of remaining oxygen that is not absorbed by negative pole and the negative pole battery container of can only overflowing causes the loss of inside battery moisture content, thereby shortens the useful life of battery.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of rational in infrastructure, and easy to use, open and close valve pressure differential is little, can effectively reduce the valve controlling sealed lead accumulator hydrogen-removing safety valve of inside battery moisture loss.
The utility model is to adopt following proposal to realize: it has a valve body that is provided with central through hole, be provided with a hydrogen chamber that disappears that wherein is filled with palladium catalyst in the valve body bottom, in the valve hole at top, hydrogen chamber that disappears, be provided with a burst disk, in the valve body central through hole, be extended with an annular boss towards the valve body upper port vertically, and form a U-loop groove between the valve interior wall, one lip valve retaining ring is on annular boss, in the valve body central through hole of lip valve upper end, clamped a burst disk, one plastic cap has been installed in the valve body upper port by 2 compressing tablets.
In the utility model, the lip valve is the circular cylinder of an acid-resisting rubber one end sealing of making, and is equipped with a circle triangle boss at the cylinder inboard wall open end, is provided with three grooves on circular cylinder inwall and end face inner surface at least, contacts with annular boss.
The utility model on the one hand, can utilize the palladium catalyst in the hydrogen chamber that disappears that hydrogen unnecessary in the battery, oxygen catalytic reaction are generated water owing to adopt said structure, is back in the battery, reduces the inside battery moisture loss, effectively prolongs battery useful life; On the other hand, owing to adopt the version of lip valve, utilize the annular boss outer surface of establishing in triangle boss that lip valve end is provided with and the valve body to contact, reach sealing, prevent that outside gas from entering the purpose in the battery, simultaneously, the groove that utilizes lip valve cylinder body and end face inner surface to be provided with, reduce the bulk strength of lip valve, accurately set its cracking pressure, when inner pressure of battery reduced, the lip valve is self-return again, valve is closed in realization, reaches the purpose of sealing; Thereby the pressure differential that can effectively reduce out valve, close valve guarantees the constant of cell internal pressure, improves battery operated reliability.Be suitable for and the supporting use of existing closed maintenance free lead accumulator.
