The mining gas electric butterfly valve is driven by an electric actuator to rotate the butterfly plate, changing the opening of the butterfly plate to control the fluid flow rate. When the butterfly plate rotates 90 degrees, the valve opens and fluid passes through; When rotated to 180 degrees, the valve closes and cuts off the fluid. Its bidirectional sealing design can adapt to the requirements of forward and reverse flow, ensuring system safety.
Mining gas electric butterfly valve is a valve designed for high explosive and highly corrosive media such as coal mine gas. It is widely used in coal mine gas extraction systems, pump rooms, power plants, mine ventilation, water treatment, fire protection systems and other scenarios, and is a key equipment to ensure mine safety production. It is mainly used in coal mine gas extraction systems, mine ventilation systems, mine water treatment systems, and fire protection systems to ensure the safe extraction and utilization of gas, adjust air flow in real time, control water flow, quickly cut off gas supply in emergency situations such as fires, and ensure the safe production of mines.
Features
Good sealing performance: Flexible sealing materials are combined with metal valve seats, and some models are equipped with dual sealing structures, which can effectively prevent gas leakage. The electric actuator can accurately control the opening of the butterfly plate, apply uniform pressure when closing, and avoid sealing failure caused by impurities.
Strong corrosion resistance: The valve body is often made of materials such as aluminum alloy and stainless steel, the butterfly plate is made of stainless steel, and the sealing material is anti-static, corrosion-resistant, and flame-retardant, which can be used for a long time in highly corrosive environments in mines.
Flexible adjustment: By adjusting the rotation angle of the butterfly plate, the flow rate and pressure of the fluid can be accurately controlled to meet the different needs of systems such as mine ventilation and gas extraction.
Explosion proof design: The electric actuator meets the mining explosion-proof standards and can be safely operated underground. Some valves also integrate gas concentration sensor interlocking function. When gas exceeds the limit, the valve will automatically close to prevent the accident from expanding.
Easy to operate: It can achieve remote control and automated operation. Some valves are equipped with manual emergency operation functions. When the power is cut off, the valve can be opened or closed through the handle. It also has multiple protection functions such as phase sequence identification protection, leakage protection, and over torque protection, making it easy and safe to use.
Application scenarios
Gas extraction system: regulate gas flow, improve extraction efficiency, and reduce accumulation risk. For example, fully open the valve in high concentration areas to accelerate extraction, and reduce the speed in low concentration areas to save energy.
Mine ventilation system: Real time adjustment of airflow to ensure air quality and prevent excessive gas concentration.
Fire protection system: Quickly cut off gas supply in emergency situations such as fires to prevent the spread of fire.
Water treatment system: controls water flow to ensure the safety of mine drainage.
