· Shockwave resistant valves

Anti-shock wave valve parameters:

Figure No. Door frame size(mm) Pressure(kPa) Ventilation capacity(m3/h)
T86-FH2500/918 900*1800 2500 6000
T86-FH1500/918 900*1800 1500 6000

FH1500/918 net pass width 900mm, height 1800mm, shock wave overpressure resistance 1500Kpa;
FH2500/918 net passage width 900mm, height 1800mm, shock wave overpressure resistance 2500Kpa;

The structure of the shockwave resistant valve is as follows:

1. There are three ventilation valves, and the pressure inside and outside the door can be adjusted by adjusting the ventilation valve.

2. The door frame is an unequal corner assembly welding frame structure.

3. The locking device is provided with 2 groups, one group is the locking shaft that is usually closed, and the handle is rotated; The other group is the emergency locking device,

4. The lower dumpling page is supported by one-way thrust ball bearings, and the spring folding is used in the middle to ensure that the door is automatically closed.

5. The sealing method is sealed with a rubber strip with a zigzag section of "9".

The appearance of the door is beautiful and generous, the pure steel structure is welded, sturdy and durable, the installation and use of maintenance are more convenient, the installation of the door frame and the wall hole as a whole, before pouring concrete, the fixed angle steel of the hinge should be checked, corrected, fixed firmly, to ensure that the upper and lower hinge holes are in a vertical line in the center, and the allowable error of different centrality is 2mm.
The airtight door, also called the underground airtight door, is installed in the passage leading to the underground parking lot from the underground main substation and the main drainage pump room, which is easy to close, can be waterproof, can also be fireproof, and can also prevent the shock wave and flame generated by accidents, and the installation and operation are also very convenient;
