The present invention belongs to the technical field of
oil mist lubrication system, and specifically relates to a fast opening and closing switching valve for
oil mist lubrication system and its
control system, comprising a main
oil mist box and a spare oil mist box, the main oil mist box and the spare oil mist box are respectively connected to a group of
piston valve bodies, the
left valve body and the right valve body are both provided with vertically arranged
piston channels, the tops of the
left valve body and the right valve body are connected to the
piston valve body; the controller seat is fixed on the oil mist outlet
pipe, the top of the controller seat is connected to the high-pressure air intake
pipe, the bottom of the controller seat is connected to the left air intake
pipe group and the right air intake pipe group, the piston valve body is provided with a columnar pressure block, and the bottom of the columnar pressure block is connected to the piston through a connecting rod. Compared with the prior art, the present invention has the following advantages: by reasonably setting the internal structure of the valve core and the controller seat, the valve core moves according to a predetermined path, realizing the automatic switching of "one open and one closed", reducing manual control, fast execution speed, realizing the
continuous operation of the oil mist
lubrication system, and extending the service life of the oil mist system.
