ZCS / DF groove type solenoid valve, the use of clamp type connection, suitable for water or liquid for industrial media, automated control or remote control of water, oil, liquid and other working media pipeline on and off.ZCS / DF groove type solenoid valve using rubber seal, so the cleanliness of the working medium is greatly reduced, with rapid opening and closing, high reliability.
Structural Principles
ZCS / DF trench solenoid valve for the diaphragm once open valve pilot-operated solenoid valve, its structure is mainly composed of a secondary valve and the main valve. According to the different state of power failure, can be divided into normally closed solenoid valve and normally open solenoid valve.
ZCS/DF groove normally closed solenoid valve
In normal position, the movable iron core seals the vice-valve port, the pressure balance in the valve cavity, the vice-valve, the main valve port is closed. When the coil is energized, electromagnetic force will be active core suction on the secondary valve open, the main valve cavity of the medium from the pilot valve leakage, so that the main valve diaphragm up and down the pressure difference, the diaphragm was quickly raised, the main valve opening, the valve is a pass state. When the coil power failure, the magnetic field disappears, the activity of the iron core reset, closed the vice valve mouth, followed by the vice valve diaphragm cavity pressure rises, the main valve diaphragm pressure to the valve seat, the valve is closed.
ZCS/DF grooved normally open solenoid valve
When the coil is energized, a magnetic force is generated, and the armature moves down under the magnetic force, pushing the cup of the secondary valve down, and the secondary valve closes. With the main valve valve up and down pressure difference tends to be equal, the main valve diaphragm by the spring and self-weight pressure to seal, the valve closed. When the coil is de-energized, the magnetic force is zero, the armature and the valve ring due to the role of the spring rises, the secondary valve open, the main valve diaphragm chamber medium through the secondary valve flow away, the pressure drops, when the pressure drops to a certain value, the main valve by the upper and lower pressure difference up, the main valve open, the valve opens.
