Description

Simple and quick connection device for oil filter pipeline

technical field

The utility model relates to a quick connection device, in particular to a simple and quick connection device for oil purifier pipelines.

Background technique

The oil filter unit is required for the overhaul of the main transformer and high-resistance, as well as for oil filtering, oil injection, and hot oil circulation for the main transformer and high-resistance. Among them, an important step in the preparation work of the oil filter before oil filtering is to connect all the oil pipelines of the oil filter with the main transformer (or high resistance) and the oil filter.

The currently used connection method between the oil pipeline and the main transformer end is as follows: Two workers shall connect one end of an oil filter pipeline with a metal iron pipe (the iron pipe is about 20 cm long and has a screw connector at one end) After stacking, use iron wire to bind, and then use screws to connect the oil inlet of the main transformer (or high resistance), and use the same method to connect the other end of the pipeline to the oil outlet of the oil filter unit to complete the main transformer (or high resistance) The connection between the oil injection port of the main transformer and the oil outlet of the oil filter unit; according to the above method, use another pipeline of the oil filter unit to complete the connection between the oil outlet of the main transformer and the oil inlet of the oil filter unit.

This connection method requires two workers, and the operation process is complicated and takes a long time, and in the process of oil filtering and hot oil circulation, unsafe factors such as oil leakage are prone to occur at the connection port of the oil pipeline. The simple and fast pipeline connection device designed by us solves the above problems, greatly shortens the time required for connection, and has been well applied in actual work.
