Publish Time: 2025-06-02
In modern industrial automation systems, valves are an important part of fluid control systems, and the efficiency of opening, closing and regulating directly affects the stability and safety of the entire production process. Partial rotary valve electric device, such as QW, QB, DQW, DQB series, is widely used in automatic control scenarios of 90-degree rotary valves such as butterfly valves, ball valves, plug valves and damper dampers due to its compact structure, flexible operation and strong adaptability. So, among many valve drive devices, why should this type of partial rotary electric device be preferred? What practical application value can it bring to various industrial sites?The biggest feature of partial rotary valve electric device is its high adaptability. This type of device is specially designed for valves that only need partial rotation (usually 90 degrees) to complete the switching action, avoiding the waste of space and energy consumption of full-stroke electric actuators, making the control more precise and the response faster. Whether in power, petroleum, chemical, food, pharmaceutical, sewage treatment and other industries, it can meet the needs of precise control of fluid media.According to different usage requirements, this series of products has been subdivided and configured. Among them, QW and DQW are outdoor electric devices with good waterproof and dustproof performance, suitable for long-term operation in open air or humid environments; while QB and DQB are explosion-proof products that meet relevant national explosion-proof standards and can operate safely in flammable and explosive gas environments. They are widely used in high-risk places such as chemical industry and natural gas.From the perspective of structure and function, Q represents full-rotation design, which is suitable for valve types that require multiple turns; while DQ represents superimposed structure, that is, a secondary reducer is added on the basis of Z-type electric device to provide greater torque output to meet heavy load or high-precision control requirements. This modular design not only enhances the versatility of the product, but also facilitates later maintenance and function expansion.In terms of operation mode, partial rotary valve electric device supports remote centralized control and on-site manual switching, which can realize intelligent management through PLC system and local operation in emergency, which improves the flexibility and reliability of the system. At the same time, the device has built-in limit switch and torque protection mechanism, which can effectively prevent equipment damage caused by overload or misoperation and extend service life.In addition, this type of electric device has strong environmental adaptability. Its internal motor, reduction mechanism and control circuit are optimized and designed to operate stably under various complex working conditions such as high temperature, low temperature, corrosive gas, etc., ensuring the safety and stability of long-term continuous operation. Some models also support signal feedback function, which can transmit the valve status to the central control system in real time to provide data support for factory automation.In summary, partial rotary valve electric device has shown strong application potential in the field of modern industrial automation control with its multiple advantages such as compact structure, strong adaptability, convenient operation, wide environmental adaptability, safety and reliability. Whether it is used in new projects or in the transformation of old equipment to improve the level of automation, it is an ideal choice to improve production efficiency and reduce operation and maintenance costs. With the development of Industry 4.0 and intelligent manufacturing, this type of electric device will play a key role in more industries and application scenarios.
