What are the things to note when setting up explosion-proof doors

Hebei Citong Door Window Co., Ltd. will help you understand what are the suggestions when setting up an explosion-proof door:

1. Explosion-proof door installation location:

1. Explosion-proof door installation location:

1. Explosion-proof door installation It is arranged on the same axis as the Tongyin well and is located in the direction of the wind flow of the Fengyin well.

2. The distance between the intersection of the outlet shaft and the wind tunnel to the explosion-proof door is at least 10 meters shorter than the distance between the main ventilation suction port of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of the air outlet of

2. Explosion-proof door closure: not less than the area of ​​the exit wellhead.

3. Explosion-proof door structure: the structure is tight, and it must have sufficient strength, as well as anti-corrosion and anti-stripping facilities.

4. Explosion-proof door seal: Explosion-proof doors must be kept closed at any time, so they are strictly tight and not leaking. Also install balanced weights or take other measures to make the explosion-proof door easy to open, and strictly prohibit the locking.

5. Requirements for the exit of explosion-proof doors: Exit of explosion-proof doors is strictly prohibited from being used against other buildings.

六、防爆門Processing and installation must meet the following requirements:

1. The door frame structure is selected as a semi-circular arch or rectangular overall style according to the tunnel shape. The material is made of 11# mines, and a I-shaped steel is welded in the center of the door frame. Each I-shaped steel has the same model, and the connection between them is welding, and the processing technology is simple. The plane degree of engagement with the door panel on the door frame is easily guaranteed.

2. The door plate is also semi-arched or rectangular, with one left and right sides, and the material is 75×75×8mm corner steel and 3mm thick steel plate. The door plate is welded to form a door plate, and the horizontally designed reinforced plate is designed so that the door plate can have sufficient resistance to pressure deformation. Similarly, because of its simple and convenient structure, the plane of the door surface is easy to protect.

3. Sealing method: The door panel and the door frame are sealed using 10×45×1660mm or 10×45×3255mm rubber strips. The rubber strip is fixed to the door plate with iron pressure strips 5×30×1620mm or 5×30×3220mm and bolts. The front of the left and right door plates are equipped with sealed rubber strips along the outer edges for one round, and the rubber strips are processed to 450 at both ends. Adhesive with chloroprene adhesive (813) to form a sealing ring with the word \”mouth\” on the left and right doors respectively.

When the explosion-proof door is closed, the mine is pressed tightly on the door frame. This forms a closed door to prevent the occurrence of wind leakage.

4. The doorway axis and the support are used to cooperate with a gap to consider sufficient adjustment gap. When the sealing rubber strips wear, their height dimensions become smaller, under negative pressure. It can still be guaranteed to seal the rubber strips tightly to prevent the sealing of the explosion-proof door.
