Regular self-lubricating scraper flowmeter

The invention discloses a regular self-lubricating scraper flow meter which is characterized in that the aims of lubricating a magnetic scraper and improving the rotating effect of the magnetic scraper are fulfilled by virtue of the action of a lubricating bearing, and lubricating oil is sprayed by virtue of the action of a first spraying cover and a second spraying cover, so that the lubricating bearing is lubricated, and the rotating effect of the magnetic scraper is improved. By means of guiding of a first flow guide cavity, lubricating oil can enter a second flow guide cavity easily, when the oil pressure exceeds the original upper limit of the pressure valve, the lubricating oil can be input into the inner wall of the shell conveniently, the lubricity of the contact face of the magnetic scraper blade and the inner wall of the shell is achieved, the friction of the magnetic scraper blade is effectively reduced, and the rotating effect is improved; and finally, the timer is beneficial for a worker to prese
