1results about How to "Reduce internal leakage" patented technology

The utility model relates to control valve technical field, concretely is a kind of flat plate type high wear-resisting multiway distribution valve, including valve body, the inside of valve body is equipped with multiple valve core driven by driving rod drive to advance, the side of valve body is fixed with valve cover, the inside of valve cover is fixed with sealing seat, sealing seat is equipped with the valve cavity corresponding with valve core position one to one, the inside of every valve cavity can detachably install wear-resisting nested ring, the inside of wear-resisting nested ring is embedded and is installed with flexible sealing ring, and the rear end of every valve core is equipped with the self-adapting compensation mechanism by auxiliary sealing snap ring and spring piece. The flat plate type high wear-resisting multiway distribution valve effectively improves the wear resistance and sealing reliability of valve core and valve body mating surface, reduces internal leakage, improves control accuracy, prolongs service life, and is suitable for stable operation under high-frequency commutation and high-pressure working condition.
