SOLENOID VALVE AND SOLENOID VALVE DEVICE

摘要

Provided is a solenoid valve, including a housing, comprising a valve head and a valve body defining a containing chamber; a stationary iron core, installed in the containing chamber; a moving iron core, disposed in the containing chamber and being movable between a lower proximal position and an upper distal position from the stationary iron core; a coil, fitted over an outer circumference wall of the valve body and configured to produce electromagnetic force for driving the moving iron core to move in the containing chamber; and an elastic spacer, disposed at at least one of the stationary iron core and the moving iron core and configured to enable the moving iron core to be spaced apart from the stationary iron core at a predetermined distance L when the moving iron core is located at the lower proximal position, so as to avoid the moving iron core from colliding with the stationary iron core.
