Yucheng Design of Coal Mine Water Sealing, Fire Blocking and Explosion Relief Device

Description :

　　Yucheng Design of Coal Mine Water Sealing, Fire Blocking and Explosion Relief Device

　　Water sealed flame retardant and explosion-proof device, structure of water sealed flame retardant and explosion-proof device, manufacturer of water sealed flame retardant and explosion-proof device

　　Safety is more important than Tai'an. The water seal fire prevention and explosion relief device is used in the coal mine gas pipeline transportation system to prevent the shock wave generated by the explosion from damaging the drainage system and blocking the flame generated by the explosion from entering the underground to prevent the accident from expanding. Therefore, the water seal fire prevention and explosion relief device is essential

　　1、 Parameters of water seal fire prevention and explosion relief device:

　　Specification and model: DN100~DN500mm.

　　The nominal pressure of the flame retardant and explosion-proof device (excluding explosion-proof components) is ≥ 1.0MPa;

　　Release pressure of explosive components: 90-120kPa;

　　Device pressure loss: ≤ 2.0 kPa;

　　Environmental temperature: (2-50) ℃;

　　Relative humidity: ≤ 95% (25 ℃);

　　Atmospheric pressure: (80-106) kPa;

　　Gas flow velocity inside the pipeline: ≤ 10m/s;

　　Gas transmission design pressure: ≤ 30kPa;

　　Sealed water quality: suspended solids ≤ 20mg/L, total hardness ≤ 6mmol/L, 6.5 ≤ pH (25 ℃) ≤ 8.

　　2、 Structure of water seal fire prevention and explosion relief device:

　　The water seal fire prevention and explosion relief device is purchased from the inlet (outlet) gas pipe, inlet water tank, explosion relief rubber, explosion relief tank, water level controller, metal diversion network, etc. The metal diversion net is made of stainless steel mesh with a mesh size of not less than 4 mesh. The pressure loss of the gas pipeline transportation water seal fire prevention and explosion relief device shall not exceed 2kPa.

　　Our company has complete equipment for explosion-proof and fire-resistant coal mine gas drainage pipelines, such asWater sealed fire and explosion prevention device,Automatic positive and negative pressure drain device, FHQbackfire arrester， The FBQ water seal explosion-proof device is made of high-quality materials, and we will not cut corners. We sincerely cooperate with you.
