Our company, designs and manufactures pneumatic baffles and butterfly valves for flue ducts of heating furnaces of various specifications. Using ASCO series solenoid valve, FISHER, Siemens and other intelligent positioners, external maintenance-free self-aligning wear-resistant rolling bearings, advanced structural design, reliable operation.
Pneumatic quick opening damper
Our company designs and produces various types of quick-opening dampers. The petrochemical industry is generally equipped with pneumatic actuators. The quick-opening dampers are normally closed and interlocked to open quickly when the system fails. Generally, the quick-opening time is less than 5S. This pneumatic quick-opening damper is a side-opening type with manual opening door, which is installed on the side of the hot air duct.
Bottom opening pneumatic quick opening damper
This is a quick-opening damper installed at the bottom of the hot air duct. It adopts a pneumatic actuator to advance and retract the door cover through a long-stroke pneumatic actuator to close and open the damper. The damper is simple in structure and reliable in use, and is a commonly used quick-opening damper.
blast doorThe explosion-proof door installed on the shell wall of the heating furnace is a safety valve to ensure the safe operation of the heating furnace. The explosion-proof door is generally made of gray cast iron, which is produced by static casting process, and the door cover is provided with thermal insulation material.
Fan inlet control valve
This kind of regulating valve is a valve specially used for the fan inlet to adjust the air volume of the fan inlet. The regulating valve is a fan-shaped rotary vane regulating valve, which makes the passing wind rotate through the regulating valve and is consistent with the rotation direction of the fan blades.
Metal compensator
The metal compensator is used to compensate the displacement of the pipe due to thermal expansion on the flue air duct, and is generally used in the hot air duct with an external thermal insulation structure. The metal expansion joint consists of several nodes, and the material of the nodes is generally stainless steel. Metal compensators should generally be pre-stretched before installation.
watch fire door
The fire door installed on the shell wall of the heating furnace is used to manually open it to observe whether the flame of the burner in the heating furnace is normal. The material of the fire door is generally gray cast iron, which is produced by a static casting process.
