Safety catalyzing valve for lead-acid storage battery

Abstract

The invention provides a safety catalyzing valve for a lead-acid storage battery. The safety catalyzing valve comprises a valve body, wherein the upper part of the valve body is hollow, and internally provided with a pneumatic safety valve of the lead-acid storage battery, and the lower part of the valve body is provided with an installing seat for a catalyst; a ventilating hole in communication with the pneumatic safety valve is arranged between the installing seat and the pneumatic safety device; an installing hole for the catalyst is arranged in the installing seat and filled with the catalyst, and a filtering layer is arranged outside the catalyst; and the catalyst is the catalyst for catalyzing hydrogen and oxygen to react to generate water. According to the safety catalyzing valve, the catalyst is filled in the lead-acid storage battery in a relatively reasonable mode with a relatively reasonable structure; the characteristics of the structure of the valve, the structure of the pneumatic safety device and the installing structure of the catalyst are organically and integrally fused; the safety catalyzing device is convenient to assemble and install without influence to the internal structure of the storage battery; and the catalyst has a long service life and high service efficiency, so water loss and floating current of the battery can be relatively reduced.

Description

technical field

[0001] The present invention relates to valves used in valve-regulated lead-acid batteries. Background technique

[0002] The lead-acid batteries used in the present invention generally have backup type, energy storage type, high temperature type, power type, start-up type and the like.

[0003] Among them, the backup type, energy storage type and high temperature type batteries are used for floating charging, and the battery is prone to defects such as excessive current and high internal temperature during floating charging. These defects directly lead to thermal runaway of the battery and end of life.

[0004] The power type and starting type batteries are under the condition of recycling. During the use of the battery, more water is electrolyzed to produce hydrogen and oxygen and discharged from the battery. The battery often ends in life due to excessive water loss. When the hydrogen concentration in the use environment reaches a certain value, it is ea...
