The working principle of electric automatic control water valve mainly depends on the control of the valve by the electric actuator. When the solenoid valve is powered on or off, the valve is controlled by the pressure of the water in the pipeline. Specifically, the electric automatic control water valve is usually composed of components such as the main valve, solenoid valve, needle valve and ball valve. When the solenoid valve coil is energized, the solenoid valve opens, and the water in the main valve control room flows out through the solenoid valve and the ball valve, causing the pressure in the main valve control room to drop, and the main valve opens to supply water. When the solenoid valve is powered off, the water in the main valve control room cannot flow out, Налягането се увеличава и диафрагмата се изтласква да затвори основния клапан .
In addition, the electric automatic control water valve also has some special functions and installation requirements. For example, the 600X hydraulic electric control valve should be installed horizontally and the valve cover should be upward. There should be drainage facilities behind the pressure reducing valve of the fire water supply system. The pressure reducing valve used in the hot water supply Проектът трябва да приеме клапана за намаляване на налягането на топла вода и да обърне внимание, за да предотврати повредата на циркулацията на горещата вода .
Електрическите задействащи механизми обикновено приемат интегриран структурен дизайн, имат функция за самодиагностика, много са удобни за използване и регулиране и могат да показват стойност на контролния сигнал, стойността на сигнала за обратна връзка и електрическата стойност на ръката .
