[0022] In specific implementation, the impurities inside the valve body 1 can be quickly guided to the inside of the external thread drain pipe 6 through the inclined plate 8. At this time, the rotating block 16 can be rotated to drive the rotating rod 13 to rotate through the bearing seat 12, so as to drive the scraper 15 and the moving plate 14 to rotate. When the scraper 15 rotates, the impurities clogging the inner wall of the external thread drain pipe 6 can be scraped. Then, the connecting block 11 is reversed. When the connecting block 11 is reversed, the internal thread ring 9 is screwed away from the valve body 1.
