Intelligent regulating valve electric device is suitable for some rotary valves (such as butterfly valves, ball valves, dampers, etc.) and similar equipment. The bracket can be used as an angular stroke electric actuator. Aluminum alloy die-casting shell, with fine and smooth, small size and light weight, maintenance-free, strong corrosion resistance and other excellent properties, because of its compact size, can be used in narrow areas.
Functional Characteristics of Intelligent Regulating Valve Electric Device
1. Strong motor
The motor designed according to the working characteristics of the valve has high starting moment, low starting current and small turning inertia. Stator winding is assembled with built-in overheat protector (automatic recovery type). When the valve is accidentally blocked, the protector controls the motor to stop and protects the safety of the whole set of equipment.
2. Small volume and large moment
The overall volume and weight are only 1/3 of the same kind of traditional products; the overall input power is small, the output torque is large, and the installation space is small; the installation and transportation is very convenient.
3. Valve opening display
The lens and the body are bonded with imported food-grade glass glue. The bonding height is strong, which makes the product pollution-free and high temperature resistant, and can effectively resist the corrosion of the harsh environment such as rain blistering.
4. Mechanical Limiting Device
No. Mechanical travel restriction bolts and stop blocks made of stainless steel can adjust the travel mechanism to the required angle. For easy adjustment, the bolt for the outer shell, after each adjustment with stainless steel nuts to lock the required position.
5. Artificial rocker
Stainless steel handle can be used to drive the valve when debugging or power off. S is clockwise and O is counterclockwise.
6. Precision Gears
The gear and shaft are made of heat treated high alloy steel. They have high strength and good resistance and can withstand long-term fatigue load impact. The gear mechanism is filled with imported food grade molybdenum base grease to complete lubrication without spot inspection or maintenance.
7. Cable Interface
There are two G1/2 waterproof cable connectors for cable and signal lines respectively to prevent interference.
8. Micro-switch
HD series adopts imported micro-switch, which has excellent and reliable contact quality, operation life, insulation performance and other indicators.
9. Servo mechanism
The built-in control module continuously compares the input signal with the feedback signal of the potentiometer. When the balance is reached, the motor stops working, and then the output shaft keeps the valve in the corresponding position until the input signal changes. Ensure continuous valve opening.
10. Control module
The control module of resin encapsulation is characterized by high decomposition, strong function, anti-vibration, long life and reliability.
11. Precision potentiometer
Imported high precision potentiometer, service life up to 30,000 times! Very suitable for small valve opening adjustment needs! Effectively ensure the accuracy adjustment of electric valves.
12. Automatic Control
Intelligent integrative device has 4-20 mA. DC input and output signal which can be controlled by computer PLC and DCS system. It can adjust the proportion and position without manual control. It can position self-locking, simple connection, stable and reliable performance, high control precision and fast reaction speed.
