The invention provides an edible oil storage tank breathing valve capable of automatically cleaning the filter membrane, comprising a valve body, an exhalation valve disc and a rain cover are installed on the top of the valve body, a central rod is fixedly connected to the bottom of the rain cover, and the exhalation valve disc There is a support ring fixedly connected to the bottom of the support ring, a filter membrane is laid on the support ring, a turntable is connected to the inside of the exhalation valve disc and located outside the central rod, and a swivel sleeve is installed on the outside of the turntable, and the interior of the exhalation valve disc is located on the outside of the swivel sleeve. The outer rotary connection has evenly distributed scrapers. A filter membrane is installed under the exhalation valve disc to prevent small particles in the external environment from entering the inside of the cooking oil storage tank. When the exhalation valve disc moves up and down to adjust the pressure, the scraper in the exhalation valve disc rotates and stretches out, The filter membrane is scraped to automatically remove the debris adhering to the filter membrane, reducing the possibility of the filter membrane being blocked, improving the safety of the breathing valve, and the multi-stage scraper can clean the filter membrane more thoroughly .

The invention discloses a hole cleaning and threading device used during machining of a titanium alloy connector for aeronautic equipment. The hole cleaning and threading device comprises a workbench,a connector hopper, a carrying disc, front cleaning tables, a rear cleaning table, a cable bearing disc and a loading disc. The workbench is of a cuboid-shaped structure, and the connector hopper isobliquely arranged at one end of the upper end face of the workbench. The carrying disc is arranged on one side of the connector hopper, and the multiple front cleaning tables are arranged on one sideof the carrying disc at equal intervals. The hole cleaning and threading device has the beneficial effects that first motors drive rotary polishing barrels to rotate to conduct polishing and removalburrs or projections in preformed holes in the connector, the effect that the inner walls of the preformed holes of the connector are smoother and rounder is ensured, and scraping damage between a metal cable and the hole walls of the connector is prevented during threading of the titanium alloy connector in the preformed holes; and in addition, the first motors are arranged in an equal-height mode, first hydraulic pumps correspondingly drive different-height first motors and the rotary polishing barrels to conduct hole cleaning treatment on the preformed holes in different-height positions onthe titanium alloy connector, and working adaptive universality of the hole cleaning and threading device is ensured.
