Before, I presented the electric ball valve introduction. Today, I am going to discuss the explosion-proof electric ball valve, which falls under the electric ball valve category. Below, I will provide information about this particular valve.
The explosion-proof electric ball valve utilizes a full-electronic execution agency, which is an integrated structure of electromechanical components. It offers organic servo operation and opening signal position feedback, as well as location indication and manual operation functions. With such powerful features and reliable performance, the wiring is made easy. The valve has proved to be very efficient, thus enhancing productivity. The explosion-proof electric ball valve is widely used in various industries, such as oil, chemical, water treatment, papermaking, power stations, heating, and light industry, which has significantly improved its functionality.
Advantages of the structural function include the following features:
1. Robust Shell: The shell is constructed using a durable aluminum alloy that undergoes anode oxidation and polyester powder treatment. This results in excellent strength and corrosion resistance. Despite its small size, it offers a high torque capacity and minimal inertia force. Moreover, it meets insulation safety standards with an F-grade rating. Additionally, a built-in thermal protection switch prevents motor damage.
2. Manual Operation: Designed with a hand wheel, this structure ensures safe and reliable operation with minimal effort. In the absence of power, the clutch handle can be pulled for manual operation, providing versatility.
3. Convenient Indicators: The indicator is strategically placed on the central axis with a protruding mirror design. This prevents water accumulation and allows for easy observation.
4. Dryer Function: To prevent internal water condensation within the actuator caused by temperature and weather fluctuations, a dryer is integrated. This ensures the internal electrical components remain dry and protected.
5. Dual Limit Switch: The actuator features both mechanical and electronic limit switches for enhanced safety. The mechanical limit can be adjusted using a rotating screw, guaranteeing reliable operation. The electronic limit switch is controlled by a cam mechanism, offering simple adjustment and accurate positioning.
6. Tingle-distance Switch: This switch provides overload protection, preventing damage to the motor.
7. Self-locking Mechanism: Utilizing a precise double snail wheel snail mechanism, the actuator enables efficient transmission with high torque, efficiency, and low noise levels. It has the added benefit of preventing reversal and ensures stability and reliability in the transmission without the need for frequent lubrication.
8. Reliable Sniler Design: The actuator incorporates a concave wheel design which maximizes the contact surface area with the worm. This design ensures a large transmission torque, balanced performance, and excellent wear resistance, resulting in a longer lifespan.
It is worth noting that the driver and connection methods of this ball valve are not limited to worm wheels, but can also include flanges and manual types, providing flexibility and adaptability to different applications.
Explosion-proof electric ball valves are specifically designed to meet safety regulations regarding explosive environments. These valves are equipped with electric actuators that adhere to explosion-proof standards, making them suitable for use in flammable and explosive areas involving liquids or gases. Their primary function is to close or adjust the flow of these substances. There are two types of explosion-proof valves: security type and explosion type. The security type utilizes DC motors, while the explosion-proof type operates with an AC motor. It is crucial to ensure that the electric actuator on the ball valve meets the necessary explosion-proof criteria to guarantee safety in hazardous environments.
