Abstract: In this paper, a kind of non-electric transfer point spray control valve with anti-plugging function is designed, which can adapt to water pressure from 0.5 to 10 MPa, service life more than 100 000 times. The working principle of the control valve is introduced, and the anti-plugging design of the inlet water of the valve plate and the design of the valve core are introduced. Because of its simple structure without electricity, it has the advantages of convenient installation, easy maintenance, low failure rate and adaptability to all kinds of bad working environment.
