Principle of baode electromagnetic valve
Direct acting solenoid valve
Principle: when energized, the electromagnetic coil generates electromagnetic force to lift off the closing part from the seat and the valve opens; When the power is off, the electromagnetic force disappears and the spring closes the closing piece on the seat and the valve closes. Features: it can work normally when vacuum, negative pressure and zero pressure
No more than 25mm.
Distributed direct acting solenoid valve
Principle: it is a direct acting and pilot operated the principle of combining, when the inlet and outlet no pressure difference, after electrify, electromagnetic force directly to the pilot valve and main valve closed, in turn, lift, the valve opens. When the inlet and outlet reach the starting pressure difference, when the power is energized, the electromagnetism first pilot small valve, the pressure of the lower cavity of the main valve increases, the upper chamber pressure drops, so that the main valve is pushed up by the pressure difference; When the power is off, the pilot valve USES the spring force or medium pressure to push the closure, moving down and closing the valve. Features: in zero pressure difference or vacuum, high pressure can also be the action, but the power is larger, the requirement must be installed horizontally.
Pilot solenoid valve
Principle: electricity, electromagnetic force open the pilot hole, the chamber pressure drops rapidly, in closed form around the high low differential pressure, fluid pressure push close up, the valve open; Power off, the spring force to close the guide hole, inlet pressure chamber through the by pass hole quickly in closing valve using a form around the high differential pressure, fluid pressure push close move down, close the valve. Features: high fluid pressure range, optional installation (to be customized) but must meet the fluid pressure differential conditions. 2. Electromagnetic valve from the valve structure and material of different on the principle of distinction, is divided into six branches small classes: diaphragm structure, step by step of moving heavy piece of membrane structure, the structure, the forerunner in straight moving piston structure, step by step piston structure, the forerunner of moving piston structure.
