I. Introduction to Sliding Gate

The plug door is a crucial auxiliary equipment for boilers, installed in the cold and hot air ducts of thermal power plant boilers where shutdown and isolation is required, such as the air ducts at the inlet and outlet of the coal mill. This product operates reliably, has flexible opening and closing, and provides tight sealing, fundamentally solving the previous shortcomings of insufficient closure and excessive closing time for isolation doors. It greatly facilitates equipment switching and maintenance shutdowns, and is now widely used in power plants across the country.

Section 2: Key Features of the Insert Plate Door:

The plug-in door features adjustable and isolating capabilities, offering flexibility and excellent isolation performance.

2. The shutter door operates normally with smooth operation of the air door switch, free from any sticking or jamming.

3. After the plug door is closed, there is no internal or external leakage, the shaft seal is in good condition, and there is no gas or air leakage.

4. High degree of automation, featuring remote, close-range, and manual operation capabilities.

5. The power distribution system can interface with the DCS, achieving automated operation effects.

Post-closing, the air leakage rate is less than 0.1%.

7. The manufacturing process for electric and manual plug-type doors complies with relevant industry standards.

Electric and manual plug-in door operation is simple, with a short installation cycle, and can be completed within a minor maintenance period.

9. Long lifespan, requires minimal maintenance after installation, and can be mounted on any angle of the ductwork.
