Electric Pneumatic Slide Gate Dampers For Boilers Flue Air Ducts And Pulverized

Product Specification

Electric Manual Pneumatic Slide Gate Damper For boilers flue air ducts and pulverized coal pipe

Product description

The slide gate damper is an important auxiliary equipment for the boiler. It is installed in the occasions where the cold and hot air ducts of the thermal power plant boilers need to be shut off and isolated, such as the inlet and outlet ducts of coal mills. The product is reliable, flexible to open and close, and tightly sealed, which fundamentally solves the disadvantages of the previous isolation door that is not tightly closed and the closing time is too long, which greatly facilitates the switching and decommissioning of equipment,Power plant.

Classification of sliding door

Electric sliding door, manual sliding door, pneumatic sliding door.

Manual plug-in door is also called manual screw gate valve. Most of them are used for unloading device. There are two types: square mouth and round mouth. The manual plug-in valve is durable, has small flow resistance, small size, light weight, convenient maintenance, and is widely used.

Pneumatic sliding door is a main control device for the flow or conveyance of powder, grain, granules and small pieces of material. It is widely used in metallurgy, mining, building materials, food, chemical and other industries to control the flow change or quickly cut off the flow. .

There is a round port with a diameter on the gate plate of the electric plug-in door. The opening and closing of the gate plate makes the round port on the gate plate completely separate from and match the path.

Features

1. The slide gate damper is an indispensable device for the safe operation system of the power plant boiler. Compared with similar products, it has a simple structure, good tightness and high temperature resistance. Abrasion resistance and other advantages, fast opening and closing speed, convenient operation, safe and reliable operation, easy maintenance and repair.

2. The slide gate damper is installed vertically or horizontally on the pulverized coal pipeline at the entrance of the combustion chamber, and the door plate is moved in the door frame by a driving device to cut off the pulverized coal mixed gas between the coal mill and the combustion chamber (boiler), and Ensure that the combustion chamber flame does not enter the pulverized coal pipeline.

Application

1. The slide gate damper adopts a new design in structure. The door is made convex and has a groove at the top for high sealing. The door is made of stainless steel and has high temperature and corrosion resistance. A high temperature resistant silicone rubber is installed between the upper and lower door frames, and the degree of sealing can be controlled by adjusting the tightness.
