600X hydraulic electric control valve is used for water supply, air conditioning and fire pipeline system. Medium: water, temperature ≤ 80 ℃. The solenoid valve is used as the pilot valve. When the solenoid valve is powered on or off, the switch of the valve is controlled by the pressure of water in the pipeline
Part of the medium at the inlet end of the valve runs along the conduit. Needle valve. Enter the upper chamber of the diaphragm. When the solenoid coil is energized, the solenoid opens. The medium in the upper chamber of the main valve diaphragm flows to the outlet along the solenoid valve and ball valve, and the pressure in the upper chamber of the diaphragm decreases. Under the action of pressure difference, the medium pressure pushes open the main valve core and the main valve opens. Start water supply
When the solenoid valve coil is powered off, the solenoid valve remains closed. At this time, the outflow channel of the upper chamber of the main valve diaphragm remains closed. As the membrane area is larger than the main valve core area, the main valve is closed under the action of the pressure difference between the two
For pool level control: when the liquid level drops to the set low level, the liquid level switch sends a signal, the solenoid valve coil is energized, the solenoid valve is opened, and then the main valve is opened to start water supply. When the liquid level in the pool reaches the set height value, under the action of the liquid level switch, a control signal is sent, and the solenoid valve is closed, so that the main valve is closed and the water supply is stopped. Such reciprocating circulation keeps the liquid level in the pool stable within a certain range
