Electric barrier door

product detailsProduct Feature

The design of the electric baffle air valve is based on the design and production of pipeline components for smoke, air, and coal powder by the Electric Power Design Institute and Jiangsu Shouchuang. The baffle valves of our power plant's smoke and air pipelines are all steel welded baffle doors. For the baffle valves of coal powder pipelines, there are castings used by user units, which can be used for the wear-resistant pipeline needs of coal powder pipelines.

The electric rectangular baffle air valve is used to regulate the working medium flow in the boiler flue gas and air duct. When the blade rotates 90 degrees, it controls the pressure, temperature, quantity and other parameters of the working medium in the system through different working medium flows. It has the characteristics of flexible rotation and excellent adjustment performance. The air door adopts a relative action type of adjacent blades. Jiangsu Shouchuang Pipeline Equipment Co., Ltd. produces air valve baffle devices in this way.

The electric rectangular baffle air valve adopts a steel plate folding and welding structure, and the blades are streamlined diamond shaped structures with sharp corners at both ends, which can change the distribution of the airflow wake. Its regulating characteristic is that the resistance coefficient is approximately linearly proportional to the blade opening within the range of 25 degrees to 75 degrees; The air door has electric, manual, pneumatic and other driving modes; There are Jiangsu's first pipeline professional design air valve control methods such as on-site, remote control, and centralized control.

The electric rectangular baffle air valve is used for the air door of the positive pressure hot air system. The shaft end bearing is equipped with a sealed air interface, which can be connected to seal air to block the leakage of hot air.

There are two types of structures for electric rectangular baffle dampers: ordinary and sealed. Ordinary type regulating air valves only play a regulating role and must be used in conjunction with other types of isolating air valves; Sealed type regulating air valve has regulating function and wind blocking function. For small capacity units, it can eliminate the need to close the baffle damper or baffle air valve.

The two sides of the blades and the inner side of the frame of the sealed rectangular regulating air valve are pressed with stainless steel sealing plates. When the blades are closed, they are tightly attached to the steel pipe and the inner side of the frame, ensuring the sealing effect and absorbing the thermal expansion generated when the blades are heated.

The rectangular regulating air valve bearing adopts self-lubricating self-aligning spherical bearings, which can absorb the bending reaction force generated by the blades under pressure, thereby ensuring that the air valve rotates flexibly and does not get stuck.
