Piston type solenoid valve is switched on to drive the valve fluid control components to generate electromagnetic forceelectromagnetic coil, pipeline control actuator is one commonly used. According to the principle is divided into: the straight type,straight type, step by step guide type three categories.
Working principle
1.Direct acting solenoid valve: power, the electromagnetic coil of electromagnetic force, the valve spool position directly pull.Power, the electromagnetic force disappears, the valve core by the reset spring.
2.Step by step direct acting solenoid valve: he is a principle of direct drive type and leading type combination. Normally closed - when the entrance and exit when no pressure, power the electromagnetic force directly open the pilot hole is connected with the main valve piston turn upward, the valve opens; when theentrance and outlet pressure to start, the power, the electromagnetic force to open the pilot hole, the main valve pistonchamber pressure drops, thus using the differential pressure and electromagnetic force pulling the main piston, valve open; power,the pilot hole closed by a spring reset, the main piston chamberpressure, promote the main piston moves down, closed the valve. Normally open and normally closed instead.
3.The pilot solenoid valve: normally closed, when the power is switched on, the electromagnetic force is the pilot valve, pilot holeopened, the main valve piston chamber pressure drops, the mainpiston cavity and a lower cavity formed on the high pressure low,thus promote the main piston subarachnoid pressure valve is opened; when the power is off, the spring force reduction andclose the pilot hole, main piston chamber pressure, in the mainpiston cavity and a lower cavity formed under low pressure,medium pressure and spring force to push a piston, valve closed.Normally open and normally closed instead.
