A conductive sheet A15 is installed at the bottom of the conductive sheet C19 through an elastic sheet 18, a connecting frame 17 is installed on one side of the valve core 14 near the top and in the middle, an inlet pipe 2 is installed on one side of the valve body 1 near the bottom, a drain pipe 7 is installed on the outer surface of the valve body 1 away from the inlet pipe 2, an electromagnetic seat 4 is installed on both sides of the outer surface of the valve body 1 near the top, a timing switch 3 is installed on one side of the electromagnetic seat 4 on one side of the valve body 1, a spring groove 12 is provided in the middle of the valve body 1, and a spring A13 is installed on the outer surface of the valve core 14 located inside the spring groove 12 through a spring seat.

[0025] like Figure 2 and Figure 3 As shown, a battery 10 is installed on the top of the valve body 1, and a light source 9 is installed on the top of the valve body 1 inside the green display cover 5 and the red display cover 6. The light source 9, conductive sheet C19, conductive sheet A15 and battery 10 inside the green display cover 5 are electrically connected to facilitate lighting up the light source 9 inside the green display cover 5, and the light source 9, conductive sheet B16, conductive sheet A15 and battery 10 inside the red display cover 6 are electrically connected to facilitate lighting up the light source 9 inside the red display cover 6.

[0026] The working principle of a timing solenoid valve based on Example 1 is as follows: after the utility model is installed, the utility model is connected to the place of use through the water inlet pipe 2 and the drain pipe 7, and the electromagnetic seat 4 is controlled by the timing switch 3 to perform timed power on and off. When the power is turned on, the valve core 14 is adsorbed by the electromagnetic seat 4, thereby driving the valve core 14 to move up, that is, connecting the water inlet pipe 2 and the drain pipe 7 to transport the fluid, and at the same time, the moving valve core 14 drives the connecting frame 17 to move up, thereby driving the conductive sheet A15 to move up, closing the conductive sheet A15 and the conductive sheet C19, thereby opening the green display.
