Embodiment Construction

[0016] specific implementation

[0017] Referring to Figures 1-4, the present invention is composed of battery tank 5, battery cover 2, positive and negative plates 6, glass fiber separator 7, colloidal electrolyte 4, safety explosion-proof valve 1, battery lead-out terminal 12 and bus bar 3, etc. The above-mentioned positive and negative plates 6 are separated by glass fiber separators 7, which are sequentially stacked and then placed in the battery tank 5 under pressure. All flame-retardant ABS engineering plastics are used, the seal between the tank covers is bonded by heat sealing, and the battery lead-out terminal 12 and the battery cover 2 are double-sealed: that is, the bottom layer uses plastic nuts 9 and is pressed tightly through plastic gaskets 10 Acid-resistant and aging-resistant silicone fluororubber sealing ring 11, the upper layer is sealed with epoxy resin terminal glue 8. The colloidal electrolyte 4 is perfused in the battery tank, and the safety explosion-p...

Abstract

This invention discloses a valve-controlled lead-acid storage battery used in subway cars composed of a battery tank, a cover, positive pole plates, negative pole plates, glass fiber baffles, a colloidal electrolyte, a safety anti-explosion valve, terminals and collecting bars, among which, said positive and negative pole plates are isolated by the glass fiber membranes, laminated and pressed in the battery tank, the ears are connected with the terminals by the collecting bars, the tank and the cover are sealed by hot seal, anti-acid and anti-ageing silico-fluoride rubber coil is set between the terminal and the cover to be fixed by plastic nuts and glued by resin, the shell is filled with colloidal electrolyte and the exhaust valve is installed on the valve base on the cover.

Description

technical field [0001] The invention relates to a valve-regulated lead-acid battery, in particular to a valve-regulated lead-acid battery for subway vehicles. Background technique [0002] The batteries used in subway locomotives used to be alkaline nickel-cadmium batteries, which had to be imported from abroad. The cost was high, the price was high, the procurement cycle was long, the procurement cost was high, and the operating cost was also high. At present, its price is 1.5 times higher than that of valve-regulated lead-acid batteries, and alkaline batteries need to regularly replenish electrolyte and adjust the specific gravity of electrolyte due to leakage, and then charge the electrolyte uniformly, the materials and energy used for maintenance The fee is high. The acid battery does not need to add electrolyte, nor does it need to adjust the specific gravity of the electrolyte. Alkaline batteries are short-circuited due to liquid leakage, and the bottom is often scor...
