Butterfly valve with filtering function

Abstract

The utility model relates to valve technical field, concretely is a butterfly valve with filtering function. It includes valve body shell, spherical shell, sealed ball and filter assembly. The both ends of valve body shell are respectively communicated with and are provided with water outlet connecting pipeline and water inlet connecting pipeline, spherical shell is located in the middle part of water inlet connecting pipeline, the upper and lower ends of spherical shell are respectively communicated with and are provided with upper communication casing and lower communication casing, the bottom end of lower communication casing is communicated with and has residue discharge pipe, the upper communication casing is communicated with water inlet connecting pipeline and has communication pipe, first valve and second valve are respectively installed on communication pipe and residue discharge pipe, sealed ball is rotatably installed in the inside of spherical shell, and the through hole is formed in sealed ball, filter assembly is located in the inside of through hole. In the technical scheme, filter assembly is arranged in the spherical shell of butterfly valve, the setting of filter screen can effectively intercept the impurities in fluid, and through rotating sealed ball, backwashing function is realized, and the impurities on filter screen can be quickly removed.
