Single-axis double-flapper door

Product Introduction

Single-axis double-baffle door is one of the series of shutter-type flue gas baffle. It adopts the double sealing structure of mechanical seal and compressed air seal to ensure 100% sealing effect. This product is made on the basis of introducing foreign advanced technology and absorbing the experience of domestic design and operation of similar products.
Single-axis double-baffle door is mainly used in smoke and air duct system for completely cutting off medium. It has the functions of full opening and 100% full closing, flexible action and reliable operation. After closing, it can ensure that no medium leaks into the pipeline behind the smoke baffle. For ordinary media, carbon steel materials can be used, and for corrosive media, nickel-based alloy materials can be used.

Performance characteristics of single-axis double-flapper doors:
1. The single-axis double-baffle door adopts a single-axis driven double-louver baffle structure, and a sealed chamber for introducing sealed air is designed in the middle of the double-layer blades, and the sealed air higher than the flue gas pressure of 500Pa is passed into the baffle, so that a sealed air isolation layer is formed between the double-layer baffles to block the passage of flue gas flow.
2. Damper opening and closing time ≤60S (can be selected according to user requirements).
3. A connecting rod mechanism is designed externally, so that several blades can be opened or closed synchronously.
4. The double louver baffle door has reasonable design structure, good blade rigidity and stable operation. The louver baffle blade sealing type: elastic seal and air seal.
5. The sealing air inlet valve is designed and installed on the double baffle. After the sealing air is introduced, the sealing efficiency of the baffle door is 100%.
6. Drive mode: pneumatic or electric.
7. The driving device is usually installed by direct connection and damper connection.
8. The electric device adopts mechatronic products, with torque protection and limiting devices and can be controlled and operated remotely. The electric device also has manual and electric switching functions for installation, debugging and maintenance.
9. Connection mode between damper and pipeline: flange seal welding connection or flange bolt connection.
10. The sealed fan and electric heater of the sealed air system can also be selected by our company and provided in complete sets.
