Abstract

The invention relates to an auxiliary tool of a converter, in particular to a water-cooled converter liquid injection and liquid drainage device. The problem that an existing manual type liquid injection tool is single in function, low in efficiency and poor in convenience is solved. The device comprises a liquid injection pipeline formed by sequentially connecting a first filter, a first electricthree-way ball valve, a water pump, a second electric three-way ball valve and a quick joint; a three-way joint is also connected between the second electric three-way ball valve and the quick jointin series, a liquid drainage side pipe is connected between a third pipe orifice of the three-way joint and a third valve port of the first electric three-way ball valve, and a third valve port of thesecond electric three-way ball valve is connected with a liquid drainage main pipe, wherein a second filter is connected with the liquid drainage main pipe in series. The device provided by the invention realizes automatic liquid injection and liquid drainage on a water-cooled converter by using one water pump by virtue of unique pipeline design, liquid injection efficiency and operation convenience are improved at the same time, and mass and large-scale production need of converters is met.

Description

technical field [0001] The invention relates to an accessory tooling of a converter, in particular to a liquid injection and liquid discharge device for a water-cooled converter. Background technique [0002] The cooling methods of the converter are divided into: natural cooling, forced air cooling, liquid cooling, phase change cooling. The converters of electric locomotives are cooled by liquid, and each converter is filled with 50-70 liters of cooling liquid. The existing liquid injection tool is a manual form, which is composed of pipelines, manual pumps, quick connectors, and hoses. It has a single function and can only perform liquid injection operations, which is difficult to meet the needs of the cooling system to remove part of the liquid or discharge the liquid. In addition, manual operation is inefficient and inconvenient. With the expansion of production scale, it is becoming more and more difficult to meet the production needs of frequent filling of cooling flui...
