The working principle of the solenoid valve:
solenoid valve in the closed chamber, in different positions with
holes, each hole leads to a different pipeline, the middle valve
chamber is, both sides are two electromagnet, which faces the
magnet coil energizing the body will be attracted to which side
live or leaked to file different oil discharge hole by controlling
the movement of the valve body, and into the hole is normally open,
the hydraulic oil will enter a different outlet pipe, and then oil
pressure to push the oil just pistons, piston and drive the piston
rod drive mechanism moving. Thus by controlling the solenoid
current is controlled mechanical movement. Looking at domestic and
solenoid valve, so far from the action can be divided into three
categories namely: direct acting, kick, pilot, and the difference
from the valve different structures and materials as well as on the
principle of reverse punch type can be divided into: diaphragm
recoil solenoid valve, piston recoil solenoid valve; pilot can be
divided into: pilot operated diaphragm solenoid valve, pilot
operated piston solenoid valve; from the valve seat and seal
material points can be divided into: soft sealing valve, solenoid
valves sealed steel, semi-steel seal solenoid valves.
