2013 
The utility model discloses a filter control valve and aims to solve the problem of complex valve switching during operation and backwashing of a traditional filter. The filter control valve comprises a valve body, a valve element, a water outlet pipeline, a water inlet pipeline and a backwashing water outlet pipeline, wherein the water inlet pipeline is arranged on one side of the valve, and the water outlet pipeline and the backwashing water outlet pipeline are symmetrically arranged on two sides of the water inlet pipeline, a first pipeline and a second pipeline are symmetrically arranged on the other side, which is opposite to the water inlet pipeline, of the valve body; and a first through hole and a second through hole are symmetrically formed in the valve element. According to the filter control valve, five pipelines are arranged on the valve body, so that the valve is applicable to simple switching between filtering and backwashing of a water treatment filter system. The filter control valve has the advantages as follows: 1, the valve is simple in structure, high in reliability and low in cost; 2, the valve is simple and intuitive in operation and particularly applicable to small household filters; 3, the valve only has a filtering gear and a backwashing gear, so that the failure rate is reduced, and the service life is prolonged.
