Electromagnetic water inlet valve with automatic pressure reducing function

The utility model provides an electromagnetic water inlet valve with an automatic pressure reducing function, which mainly comprises a valve body, a U-shaped bracket (the bracket is rotated by 90 degrees to right), an inner sleeve, an electromagnetic coil, a piston, a spring, an iron core, a fast interface, a sliding block, a shaft, a sealing ring, a sealing gasket, a rubber cup and a gasket, wherein pressure reduction is conducted at a water inlet to enable water supply inside the valve to be smooth and pressure to be reduced, so that the piston can move up and down flexibly, and high pressure impacting on the iron core and the valve body can not happen any more; and the pressure in the inner sleeve in the valve is reduced, simultaneously the number of laps of the electromagnetic coil can be reduced, and the spring with smaller elastic coefficient can be chosen for use, so that the cost can be saved.
