    摘要： An anti-siphon one-way valve includes a valve seat, a valve core, a return spring, and a Y-shaped ring. The valve seat has an inlet and an outlet. The valve seat has a valve cavity therein. The valve cavity communicates with the inlet and the outlet respectively. The valve core is slidably mounted in the valve cavity. The Y-shaped ring is installed on the valve core and leans against the side wall of the valve cavity. The Y-shaped ring has a Y-shaped cross-section. The return spring is fitted on the valve core. The present invention provides a better anti-siphon effect, and the requirements for precision in size and installation are lower, and the production cost is reduced.
