Product description

cold and hot air, isolation and adjustment door have the following characteristics
1. The air door has adjustment, isolation and sharing, adjustment flexibility, its isolation performance is good.
2. When working normally, the damper switch is flexible and free of jam.
3. After closing, there is no leakage, leakage, good shaft seal, no leakage or air leakage.
4. High degree of automation, with remote, close - range, and manual operation.
5. The power distribution system can be connected with DCS for automatic operation.
6. The air leakage rate after closing is less than 0.1%.
7. The manufacturing process meets the relevant industry standards.
8. Easy operation, short installation cycle, can be completed within the minor repair period.
9. Long service life, no maintenance is required for a single installation, which can be installed on the duct at any Angle.

Our company (factory) products throughout the country the size of the current power plant (station), especially used in delivering, induced draft fan, dust catcher, and contact on the door, two-way mother tube mill and use effect is very good, for the power plant (stand) save money more than tens of millions of yuan, my company to another, secondary air adjusting door, design, production also has the unique feature, flexible adjustment, no jamming phenomenon, no leakage, leakage phenomenon of the shaft sealing system.

Structure and features

1. The reliable drive and compression of the valve structure are the same instruction, which takes precedence over the previous drive step. When the switch is in place, the pressure is another step, and the operation degree and maintenance procedure are shortened.
2. The special plate rack drive is adopted in the pneumatic door drive parts, which is flexible and durable. It is preferred to the previous phenomenon of worm screw, steel wire, chain easy to die, ash accumulation and high temperature deformation.
3. The multi-function limit device used in the air door positioning system is accurate when the switch is in position and has secondary protection device.
4. Manual air door, design reasonable switch light and flexible.
5. Cold and hot air doors are driven by different structures and can be selected according to the needs of users.
6. If there is dust in the duct, a reasonable sewage system is provided.
7. According to the work needs to design the switch in place time.
