Abstract

The invention relates to the field of heat dissipation of liquid cooling systems of converters, in particular to a dual-closing quick connector. The dual-closing quick connector solves the technical problem that currently, a device capable of achieving quick connection and also achieving pipe closing after disconnection does not exist. The dual-closing quick connector comprises a tubular male connector assembly and a tubular female connector assembly. The male connector assembly comprises a first pipe body and a pipe joint connected with a non-connecting-opening end of the first pipe body. A slider is arranged at the connecting-opening end of a second pipe body in a sliding opening and closing mode. The female connector assembly comprises the second pipe body and an ejector rod, and a slider is arranged at the connecting-opening end of the second pipe body in a sliding opening and closing mode. The outer diameter of the connecting-opening end of the first pipe body is smaller than the inner diameter of the connecting-opening end of the second pipe body, and the connecting-opening end of the first pipe body is matched with the slider so as to open and close the female connector assembly. An ejector head is matched with a sliding sealing block so as to open and close the male connector assembly. The dual-closing quick connector is ingenious in design, capable of achieving fast connection and closing between the connector assemblies, and wide in application range.

Description

technical field [0001] The invention relates to the heat dissipation field of a converter liquid cooling system, and is mainly applied to the connection between a pipeline and a heat dissipation system in a converter liquid cooling circuit, and is specifically a double-closed quick joint. Background technique [0002] At present, there are many ways to adopt the heat dissipation system of the locomotive converter, among which the liquid cooling heat dissipation system is one of the more commonly used ones. The basic principle of liquid cooling and heat dissipation is that the heat dissipation element takes away the heat through the coolant, and the liquid circulates through the pipeline. The liquid circulation is mainly to dissipate the heat of the circuit element, so there must be a reliable connection between the pipeline and the cooling system of the element, and at the same time, the replacement of the pipeline and the element does not affect each other, which requires t...
