Metal compensator
Metal compensator
The metal compensator is used to compensate the displacement of the pipe due to thermal expansion on the flue duct, and is generally used for hot air ducts with external thermal insulation structures. The metal expansion joint is composed of several corrugated joints, and the material of the corrugated joints is generally stainless steel. The metal compensator should generally be pre-stretched before installation.
Fan inlet control valve
Fan inlet control valve
This kind of regulating valve is a valve dedicated to the inlet of the fan and used to adjust the air volume at the inlet of the fan. The regulating valve is a fan-shaped rotating blade regulating valve, which causes the passing wind to rotate through the regulating valve, which is consistent with the direction of rotation of the fan blades. The fan inlet regulating valve can be equipped with a manual actuator or a pneumatic actuator.
Explosion-proof door
Explosion-proof door
The explosion-proof door installed on the wall of the heating furnace shell is a safety valve to ensure the safe operation of the heating furnace. When the operating pressure of the heating furnace exceeds the design value, the explosion-proof door will automatically open to release the furnace pressure and ensure the safety of the heating furnace. The explosion-proof door is generally made of gray cast iron, which is manufactured by static casting process, and the door cover is equipped with heat insulation material.
Watch the fire gate
Watch the fire gate
The fire-watching door installed on the wall of the heating furnace shell is used to manually open and observe whether the flame of the burner in the heating furnace is normal. The fire door is generally made of gray cast iron, which is manufactured through a static casting process.
Bottom-opening pneumatic quick-opening damper
Bottom-opening pneumatic quick-opening damper
This is a quick-opening damper installed at the bottom of the hot air duct. It uses a pneumatic actuator to advance and retract the door cover through a long-stroke pneumatic actuator to close and open the damper. This kind of damper is simple in structure and reliable in use, and is a commonly used quick-open damper.
Pneumatic quick opening damper
Pneumatic quick opening damper
Our company designs and produces quick-opening dampers of various forms and specifications. 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. The pneumatic quick-opening damper is a side-opening type, with a manual opening door, installed on the side of the hot air duct.
Large flue baffle
Large flue baffle
With the expansion of petrochemical plants, the specifications of flue baffles have become larger and larger. Our company has actively improved and perfected the design and manufacture of large flue baffles, and has many application achievements. The board has significant advantages.
Pneumatic rectangular flue baffle
Pneumatic rectangular flue baffle
The flue baffle is a valve installed on the flue duct of the heating furnace for switching or adjusting functions. The flue baffle is complete with an actuator, generally a pneumatic actuator or an electric actuator.
Sealed double baffle
Sealed double baffle
The sealed air double baffle is a kind of baffle or butterfly valve that can achieve 100% isolation. The main structural feature is that the valve plate is a double-layer structure. The cavity in the middle of the double-layer valve plate enters the sealing air, and the pressure of the sealing air is higher than that of the pipeline. The internal medium pressure is used to achieve full sealing.
Casting valve plate flue butterfly valve
Casting valve plate flue butterfly valve
The cast valve plate flue butterfly valve is a special flue butterfly valve. The valve plate is cast in one piece. The material is generally ductile iron or stainless steel. Due to the three-dimensional structure of the butterfly valve, it has strong resistance to deformation, high temperature and corrosion, so , This kind of butterfly valve is suitable for the top flue of heating furnace. The sealing surface is machined and matched to ensure high sealing performance and long-term operation without jamming.
