Embodiment Construction

[0016] specific implementation

[0017] see Figure 1-4 , the present invention is composed of a battery tank 5, a battery cover 2, positive and negative plates 6, a glass fiber separator 7, a colloidal electrolyte 4, a safety explosion-proof valve 1, a battery lead-out terminal 12 and a bus bar 3, etc., the positive and negative electrodes Plates 6 are separated by glass fiber separators 7, stacked in sequence and placed in the battery tank 5 under pressure. The tab 15 of the pole plate 6 is connected to the battery lead-out terminal 12 by the bus bar 3, and the tank cover is all made of flame-retardant ABS engineering plastics, the seal between the tank covers is bonded by heat sealing, and the double sealing method is used between the battery lead-out terminal 12 and the battery cover 2: that is, the bottom layer uses a plastic nut 9, and the acid-resistant and aging-resistant silicon is pressed tightly through the plastic gasket 10. Fluorine rubber ...

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, an...
