:< Anti-shock wave doors are mainly used at the bottom of mines and coal mines. When danger occurs in the underground explosive depot, the shock wave will push the explosion-proof door outwards, which plays a role in releasing and mitigating the shock wave.
:3 Instructions for use of anti-shock wave valve
:
:< This design is suitable for ventilation negative pressure<
< Welded steel pipes are used in reverse wind and do not need to be properly kept during normal operation
< Necessary measures should be taken to prevent deformation when transporting explosion-proof doors
< The installation of the door frame of the explosion-proof door must be closely coordinated with the mining industry to prevent deformation
< The door frame and the door leaf should be matched closely, and rubber should be added to the back of the center column of the door frame to prevent air leakage
< Part number<
< When installing the hinge, lubricate it to ensure flexibility
< All explosion-proof doors should be painted with red camphor and then black paint.
:3 Requirements and methods for anti-shock wave valves in explosive depots
:
:< Installation requirements:
< When installing anti-shock wave doors, follow the installation instructions Method, after installation, it should be vertical and flat, and it should be flexible to open. Then close the explosion-proof door, place the blocking rods on the fixed frames on both sides of the door frame, and bury the door with sand, gravel or soil <
< cm under the outer door.
< Installation method:
< (<
<) First organize and measure the width and height of the tunnel entrance to ensure that the entire explosion-proof door (including pre-embedded parts) is placed .
< (<
<) Place the two doors flat on the ground, arrange the sealing rubber plates between the two doors, and fix the two doors with bolts, ready for installation.
< (<
<) Correct the direction to ensure that the explosion-proof door can only open outward, and then stand the two doors at the mouth of the well at the same time.
< (<
<) After adjustment, use wooden supports to fix the overall door.
< (<
<) Start building walls and fixing them according to the design of the wellhead.
< (<
< ) After the wall solidifies, close the explosion-proof door, place the blocking rods on the fixed frames on both sides of the door frame, and seal the door with sand, gravel or soil under the outer door. Buried <
< cm, it can be used normally. 3 copies

:3 Repair and maintenance of anti-shock wave valves in explosive depot
:
:< (<
< ) Any anti-rust material Any areas that fall off or are knocked off should be reapplied at any time.
< (<
<) If the sealing rubber strip is damaged or degummed, it should be replaced or bonded in time. The replacement period of the sealing strip is about <
< years.
< (<
< ) If there is rust on the pivoting part of the door, it should be scrubbed clean and re-oiled.
