Mining gas electric butterfly valve is a valve designed for high explosive and highly corrosive media such as coal mine gas. It is mainly used in coal mine gas extraction systems, pump rooms, and power plants, and has functions such as explosion-proof, corrosion-resistant, and bi-directional sealing.
function
Explosion proof safety design: Adopting a mining explosion-proof electric actuator, it has passed coal safety certification and meets the explosion-proof requirements of underground gas environment.
Corrosion resistant material: The valve body is often made of ductile iron, cast steel or stainless steel, and the sealing surface is covered with corrosion-resistant materials such as nitrile rubber and polytetrafluoroethylene, which are suitable for strong gas corrosion.
Bidirectional sealing structure: The soft sealing butterfly plate design ensures bidirectional pressure sealing, with low flow resistance and zero leakage, suitable for pipelines that frequently open and close.
Strong corrosion resistance:
The valve body material can be selected from WCB cast steel or 304/304L/316/316L stainless steel, suitable for corrosive media such as acid and alkali liquids in mines.
The sealing ring is made of PTFE or stainless steel, which has the dual advantages of metal hard seal and elastic seal, and is resistant to low temperature, high temperature and corrosion.
Good sealing performance:
Adopting a three eccentric sealing structure, the valve seat and butterfly plate have almost no wear, and the sealing effect increases over time.
The sealing surface of the disc plate is welded with cobalt based hard alloy, which is wear-resistant and has a long service life.
Bidirectional sealing function, installation is not limited by the flow direction and spatial position of the medium.
Application scenarios
Gas extraction system: As a key control equipment, it ensures the safe extraction and utilization of gas, and prevents explosion accidents caused by leaks.
Mine ventilation system: Real time adjustment of airflow to ensure air quality in the mine and dilute gas concentration to a safe range.
Mine water treatment system: controls water flow, prevents sewage backflow or leakage, and protects the mine environment.
Fire protection system: Quickly cut off gas supply in emergency situations such as fires to prevent the spread of fire.
