Abstract
The invention discloses a railway brake valve with an automatic lubricating oil circulating function. The railway brake valve comprises a main valve body assembly, a main piston rod, a slide valve and a main valve lower cover, wherein the main piston rod is provided with a lubricating oil circulating device and provided with an oil way inside, an oil outlet of the oil way aligns to an oil inlet of the upper end face of the slide valve to communicate the upper end face with the work face of the slide valve. Since the lubricating oil circulating device is additionally arranged on the main piston rod, lubricating oil in the main valve lower cover is extracted to the upper end face of the slide valve, flows to the work face to generate oil film through the oil inlet of the upper end face of the slide valve, redundant lubricating oil flows back to an oil tank of the main valve lower cover along two sides of the slide valve. Thus, the slide valve vertically moves during working and is lubricated, lubricating of a slide valve pair is effectively guaranteed, existence time of the oil film is prolonged, slide abrasion is reduced, work environment of the slide valve pair is improved, and service life of the slide valve pair is prolonged.
