Mining water sealed explosion-proof device DN350 FBQ-4 mining explosion-proof device
The DN350 FBQ-4 mining water sealed explosion-proof device is used to extract or discharge gas through the water cover during normal drainage. The automatic water addition device can keep the water seal of the water sealed explosion-proof device constant at the preset position; Once an explosion or combustion occurs inside the gas pipe, the explosion wave and flame are isolated by the water seal, and at the same time, the explosion-proof cover rubber plate is opened or broken, releasing the explosive energy. When gas is pumped out, the gas enters the water through the inlet bend, then separates from the water and is discharged through the outlet bend. The inlet and outlet pipelines are isolated by a water seal; When an explosion occurs at one end, a continuous explosion cannot be formed under the isolation of the water seal. At this time, the rubber plate of the pressure relief device is flushed open to release pressure, protecting the safety of the well, pumping station equipment, and users.
