Item name: gravity explosion-proof door with horizontal arrangement

Technical requirements for gravity type explosion proof doors:

1. swing type explosion-proof door should adopt circular or rectangular structure.

2. the action pressure of gravity explosion-proof door is used for the beam type explosion-proof door of coal bunker. According to the 1KPa operation pressure design, it is used for the gravity type explosion-proof door of the flue, according to the operation pressure design of not less than 2KPa.

3. there should be a good sealing joint between the door plate and the base of the gravity type explosion-proof door to prevent leakage. The sealing strip shall be an elastic flame retardant material, and the sealing structure shall be easy to disassemble and replace the sealing material.

4. the rotating mechanism of gravity explosion-proof door should be of little friction, no rust and no oil lubrication.

5. gravity type explosion-proof door, in the door swing about 90 degrees position should be set back frame, prevent the door plate big angle turn, damage rotating mechanism.
