Abstract

The invention relates to a manufacturing method of a combustion chamber for a silver-zinc battery. The manufacturing method comprises the manufacturing steps of manufacturing a combustion chamber body with a partial-thread air inlet and a full-thread air outlet; manufacturing a joint of a full-thread air inlet and a full-thread air outlet; adjusting the threaded connection position of an air guide tube with two ends in threaded connection with the air outlet of the combustion chamber body and the air inlet of the joint according to a mounting position, and then welding the connection parts between the air guide tube and the combustion chamber as well as the joint by silver brazing; and then bluing to complete the manufacturing of the combustion chamber for the silver-zinc battery. According to the invention, the two ends of the air guide tube are in threaded connection with the air outlet of the combustion chamber body and the air inlet of the joint respectively, so that the adjustability of the mounting position and the mounting mode are improved; a lug boss is adopted at the outer end of the air outlet of the combustion chamber body, so that the effective length of the threaded connection is increased; the ports of the air outlet of the combustion chamber body and the air inlet of the joint are conical, so that the welding length of the silver brazing is increased; and the reliability of the combustion chamber is improved when a gas generator works.

Description

technical field [0001] The invention belongs to the technical field of zinc-silver batteries, in particular to a method for preparing a combustion chamber for zinc-silver batteries. Background technique [0002] Zinc-silver reserve battery has unique characteristics such as high specific energy, high specific power, large current discharge, stable discharge voltage, high voltage accuracy, good reliability and safety. Zinc-silver batteries are widely used as DC power supply in high-power devices in countries all over the world. Zinc-silver reserve battery is composed of welding wire socket, gas generator, liquid reservoir, combined plate group, electric heater, battery pack casing and other components. When in use, connect the external activation power supply through the welding wire socket to ignite the gas generator to generate sufficient pressure, inject the separately stored electrolyte into the combined plate group within the specified time, activate it to establish an ...
