The actuator of the Check Valve is a fully electronic electric actuator, which adopts a mechatronic structure and has functions such as in-machine servo operation and opening signal position feedback, position indication, and manual operation. It has powerful functions, reliable performance, and simple wiring. The use of Universal Valve has been greatly improved and improved in terms of work. The purpose of the Universal Valve has been greatly improved and improved in terms of work. It can be widely used in petroleum, chemical industry, water treatment, papermaking, power stations, heating, light industry and other industries.
1. Shell: The shell is made of hard aluminum alloy, anodized and polyester powder coated, with strong corrosion resistance and protection level of IP67.
2. Motor: Fully enclosed squirrel cage motor with small size, large torque, small inertia force, insulation grade F, and built-in thermal protection switch to prevent damage to the motor.
3. Manual structure: The design of the handwheel ensures safety, reliability, labor saving and small size. When power is off, manual operation can be performed by pulling the clutch handle.
4. Indicator: The indicator is installed on the central axis and adopts a protruding mirror design, which does not accumulate water and is easy to observe.
5. Dryer: It can prevent moisture condensation inside the actuator due to changes in temperature and weather, and keep internal electrical components dry.
6. Limit switch: mechanical and electronic dual limit. The mechanical limit can be adjusted by rotating the screw, which is safe and reliable; the cam mechanism controls the electronic limit switch, the adjustment mechanism is simple to adjust and the positioning is accurate.
7. Torque switch: It can provide overload protection to prevent damage to the motor.
8. Self-locking: Using a precision double worm gear mechanism, it has high transmission efficiency, large torque, high efficiency, low noise, prevents reverse rotation, and the transmission part is stable and reliable, no need to refuel.
9. Worm gear: The concave gear design ensures a large contact surface with the worm, large transmission torque, balance and wear resistance, and long service life. Of course, the driving method and connection method of this Check Valve are not limited to worm gear, but also flange type, manual type, etc.
Characteristics of the Check Valve: It means that the electric actuator on the Check Valve meets the explosion-proof standard and is used in occasions that require explosion-proof, such as liquids or gases and other flammable and explosive places in the chemical industry. It is used for opening and closing Universal Valve. Close or adjust. Explosion-proof Universal Valve can be divided into two types: intrinsically safe and explosion-proof. The intrinsically safe type uses a DC motor, and the explosion-proof type uses an AC motor.
