Importance of DC Electric Valve Motor in Motor Operated Control Valve
Electric valves are indispensable core components in modern industrial and civil fields, and are widely used in water treatment, agricultural irrigation, household soft water valves, etc. They achieve efficient and precise fluid control by driving the valves to open or close or adjust the flow through motors.
Function of the Electric Valve Motor
| Function | Description | Application Advantage |
|---|---|---|
| High Torque Output | Provides High torque drives the valve open or closed | Ideal for ball and butterfly valves in water systems. |
| Precision Control | Enables multi-position valve adjustment with feedback systems. | Perfect for flow regulation in industrial systems. |
| IP54/IP67 Protection | Dustproof and waterproof design for harsh environments. | Ensures durability in outdoor or corrosive conditions. |
| Compact Size | Space-saving design for tight installations. | Suitable for multi-channel valves and portable devices. |
Working Principle of Electric Valve （Motor Operated Control Vlave）
A. Structural Principle
Electric valves utilize high flatness design with two plane surfaces to achieve sealing and flow control. The fixed sealing component (static seal) and moving sealing component (dynamic seal) are designed with different hole patterns, allowing the valve to form different fluid channels at different positions, thereby achieving five functions: water production, backwashing, salt absorption + slow washing, water replenishment, and forward washing.
(Note: The filter valve supports only three functions: water production, backwashing, and forward washing.)
B. Control Principle of Electric Valves
Automatic valves are controlled by a microprocessor system, which activates based on time, flow rate, or water quality signals. The operation process is as follows:
| Step | Description |
|---|---|
| 1. Signal Start | The system starts when a signal (based on time, flow rate, or water quality) is received. |
| 2. Drive Mechanism | The drive mechanism rotates the valve disk to the desired position. |
| 3. Position Feedback | Once the valve disk reaches the correct position, the position signal is sent back to the microprocessor, stopping the operation. |
| 4. Cycle Control | When the next signal is received, the system restarts and moves to the next position, repeating the process to achieve the required functions. |
This system ensures precise automatic control of the valve.
Why do Electric Valves Require Electric Valve Gear motors?
