Abstract
The utility model discloses a kind of lead accumulator disjunctor process safety valve, comprise multiple safety valve be disposed on intercell connector, safety valve is the hollow cylinder be enclosed to form by perisporium and roof, the inwall of described roof and side perisporium offers the air discharge duct of connection, air discharge duct end extends to inwall exit, and described air discharge duct end is the triangular structure of introversion.Just cover the utility model when battery charging terminates undercarriage, can ensure that in battery, too much gas is got rid of in time and do not jump valve, improves the consistency of battery open circuit voltage and the reliability of voltage combo, and significantly improve operability and work efficiency.
Description
Technical field
the utility model relates to lead accumulator field, is specifically related to a kind of lead accumulator disjunctor process safety valve.
Background technology
Electric motor car valve-regulated sealed DZM series lead accumulator now generally uses, and this series battery, for use in groups, is all through producer's acid dosing and charging, carries out capacity and open circuit voltage combo is dispatched from the factory.In order to ensure battery after acid dosing and charging before packaging the stability of open circuit voltage and consistency during this, thus ensure the reliability of combo, after battery charging end undercarriage leaves standstill a period of time, usual employing covers the method for disjunctor process safety valve (being also disjunctor fur cap), avoid the pole plate of inside battery and air bump contact to be oxidized, thus slow down the decline of battery charge state and open circuit voltage.
As shown in Figure 3, there is following defect and deficiency in the disjunctor fur cap of current use: (1) battery removes lid fur cap again after standing a period of time, there is the restriction in place and space, operates very inconvenient, and can not jump valve in standing period by absolute guarantee's battery.(2) if just cover fur cap when battery charging undercarriage, operation can be very convenient, but battery is in standing period, and because there being gas not get rid of in advance in battery, the fur cap of percentage of batteries can tripping or displacement.Two kinds of negative consequences will be produced, one be the open circuit voltage of battery consistency decline, the reliability decrease of open circuit voltage combo; Two is battery washing steps below, and inside battery is easily intake.These all can produce more serious harm to battery or battery pack.
summary of the invention
The technical problems to be solved in the utility model is to provide a kind of lead accumulator disjunctor process safety valve, when battery charging terminates undercarriage with regard to lid valve, can ensure that in battery, too much gas is got rid of in time and do not jump valve, improve the consistency of battery open circuit voltage and the reliability of voltage combo, and significantly improve operability and work efficiency.
The utility model is achieved through the following technical solutions:
A kind of lead accumulator disjunctor process safety valve, comprise multiple safety valve be disposed on intercell connector, safety valve is the hollow cylinder be enclosed to form by perisporium and roof, the inwall of described roof and side perisporium offers the air discharge duct of connection, and air discharge duct end extends to inwall exit.
The further improvement project of the utility model is, described air discharge duct end is the triangular structure of introversion.The easy valve opening of triangular structure.
The utility model further improvement project is, described exhaust groove width 2mm, dark 0.75 ~ 1mm, thick 2mm, the Zhou Bihou 1.5mm of the roof outside described safety valve air discharge duct.The existing safety valve wall of wall ratio of safety valve suitably thickeies, and increases tightness.
The utility model further improvement project is, the air discharge duct on described roof is located at center, and the air discharge duct on the perisporium of side is vertical with the air discharge duct on roof.
The utility model compared with prior art, has following obvious advantage:
The utility model is owing to the inwall of roof and side perisporium offering the air discharge duct of connection, and air discharge duct end extends to inwall exit.The gas that inside battery produces can be diffused into safety valve inwall exit in time along the air discharge duct of safety valve, and the position that safety valve inwall is thicker, because interior wall thickness cracking pressure value is large, the tightening state of valve closing can be in always, can ensures that safety valve is not shifted.
Accompanying drawing explanation
Fig. 1 is the utility model elevational cross-sectional view.
Fig. 2 is the utility model upward view.
Fig. 3 is existing disjunctor safety valve elevational cross-sectional view.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises three safety valves 2 be disposed on intercell connector 1, safety valve 2 is the hollow cylinders be enclosed to form by perisporium and roof, the inwall of described roof and side perisporium offers the air discharge duct 21 of connection, air discharge duct 21 end extends to inwall exit, and described air discharge duct 21 end is the triangular structure 22 of introversion.Air discharge duct on described roof is located at center, and the air discharge duct on the perisporium of side is vertical with the air discharge duct on roof.
Thick 2mm, the Zhou Bihou 1.5mm of roof outside described safety valve air discharge duct.The wide 2mm of described air discharge duct 21, dark 0.75 ~ 1mm.
Operation principle:
Turn down the valve opening value of safety valve at 10-15KPa, valve closing value is at 5-10KPa.The gas that inside battery produces can be diffused into safety valve inwall exit in time along air discharge duct, exhaust cell wall is thinner, reaching necessarily can be slightly protruding when pressing, exit is because being designed to the triangular structure of easy valve opening, gas in battery at low pressures will valve opening exhaust, and inwall beyond safety valve air discharge duct is thicker, because interior wall thickness cracking pressure value is larger, the tightening state of valve closing can be in always, can ensure that safety valve is not shifted.
