What is the purpose of a double sealed single shaft round baffle door?

The double-sealed single-shaft circular baffle door is mainly used in the air duct and flue of power plant to intercept or adjust the flow of medium, and can also be used in the air duct and flue in other industries. Flue gas baffle doors are generally required to be 100% tight under the action of the maximum differential pressure. The flue gas baffle door is usually of the double-layer louvered type, and in addition to the sealing elements on each layer of the baffle door, the sealing gas is usually introduced into the cavity of the two-layer flue gas baffle door to further improve the tightness of the flue gas baffle door.

The double-sealed, single-shaft circular baffle door can make all the flow of the medium in a certain pipeline of the system cut off or the flow rate of the medium changes with the control. For the double-sealed single-shaft circular baffle door with a small diameter, it has two functions of intercepting and adjusting the flow of the medium, and for the round damper with a large diameter, its linear adjustability is not obvious, and its interception function is mainly applied.

The desulfurization baffle damper belongs to a device used in the desulfurization system of thermal power plants, specifically a baffle door. What are the characteristics and uses of the desulfurization baffle damper?

1. The desulfurization baffle damper is easy to corrode due to the sulfur dioxide contained in the air duct, and the 316L material is selected for design and production.

2. In order to make the damper door panel not easy to deform under high temperature, the desulfurization baffle door is designed with double-layer 316L plate, and there is a reinforcing channel steel between the double-layer plates, with a single-layer plate thickness of 5mm and a total thickness of 10mm. Huaye double louver desulfurization baffle damper shaft head, bearing, sleeve and shaft are made of several different high-temperature, wear-resistant and corrosion-resistant materials.

3. The electric device and the damper shaft are integrated, there is no gap, and the air leakage rate is less than 1% after closing

4. There is a multi-functional limiting device on the electric device, and the switch is in place accurately.

5. There is a DCS interface in the flue gas baffle distribution cabinet to achieve the effect of automatic operation.

6. It has adjustment, isolation and sharing, flexible adjustment and good isolation performance.

7. The double louver desulfurization baffle damper switch is flexible, no jamming, no internal leakage, no external leakage, and good shaft sealing.

8. Huaye brand flue gas baffle has a high degree of automation, and the inlet flue baffle isolation door of the dust collector has the functions of remote, short-distance and manual operation.

Double-sealed, single-axle round baffle door.

It is okay for the oil tank to be cleaned and injected with nitrogen pneumatic fire construction! Nitrogen is an inert gas.

It may be that the tip of the hook head is not at the right time, and when the needle rises 2 to 3 mm, the tip of the hook head is turned to 1 mm above the eye of the needle
