Plug in type isolation door

 

1、 Overview of plug-in isolation doors:
Plug in type isolation doors are important auxiliary equipment for boilers, installed on the cold and hot air ducts of boilers in thermal power plants where isolation is required, such as the inlet and outlet ducts of coal mills. The plug-in type isolation door is reliable in operation, flexible in opening and closing, and tightly sealed, fundamentally solving the shortcomings of previous isolation doors that were not tightly closed and had long closing times. It greatly facilitates equipment switching and shutdown maintenance, and has been widely used in major power plants across the country.    

2、 The main characteristics of plug-in isolation doors are:
1. The plug-in isolation door has adjustable and shared isolation functions, flexible adjustment, and good isolation performance.
When the plug-in type isolation door is working normally, the air door switch is flexible and there is no jamming phenomenon.
After the plug-in isolation door is closed, there is no internal or external leakage, the shaft seal is good, and there is no air leakage or air leakage.
4. High degree of automation, with remote, close range, and manual operation functions.
5. The distribution system can be integrated with DCS to achieve automated operation.
6. The air leakage rate after closure is less than 0.1%.
7. The production process of electric and manual plug-in isolation doors complies with relevant industry standards.
8. Electric and manual plug-in type isolation doors are easy to operate, have a short installation cycle, and can be completed during minor repairs.
9. Long service life, basically no maintenance required after installation, can be installed on any angle position of the air duct.
10. Electric and manual plug-in isolation doors have low investment and quick results.

   3、 Technical parameters of plug-in isolation door:

1) Model: FZM-B (length) × (width) × H (height)
Note: A × B can be various specifications of air ducts such as rectangular, circular, etc., to be determined by the user.

The thickness of the H air door is generally 300-600mm.
