1Mining gas special butterfly valveProduct Introduction
The specialized equipment designed for coal mine gas drainage system has the characteristics of bidirectional pressure bearing, bidirectional sealing, anti-static, and anti-corrosion, and is suitable for high explosive and highly corrosive medium environments.
IIMining gas special butterfly valvefeature
Bidirectional sealing design: not limited by the flow direction of the medium, can be installed in any direction, ensuring reliable sealing performance.
Explosion proof and anti-corrosion: Adopting special materials and structural design to meet safety requirements in high explosive gas environments, while also having strong corrosion resistance.
Automation adaptation: It can be used in conjunction with the control box of the mining explosion-proof electric device to achieve connection with the DCS system and meet the requirements of automation control.
Applicable scenarios
Mainly used in the pipelines of coal mine gas drainage systems to ensure long-term stable operation under high explosive and corrosive medium conditions.
The main product advantages are reflected in safety performance, sealing performance, and applicability:
safety design
All products have passed MA coal safety certification and explosion-proof certification, adopting explosion-proof design, suitable for flammable and explosive environments such as gas pipelines in coal mines. Some models support external programming control and can be paired with dedicated actuators for remote operation.
sealing performance
Adopting a soft sealing structure and a metal hard alloy sealing surface, it has bidirectional sealing function and can be installed in any direction without being restricted by the flow direction of the medium. The sealing ring is made of stainless steel material, which has strong corrosion resistance and maintains stable sealing performance within the temperature range of -150 ℃ to 150 ℃.
Wear resistance and pressure resistance
The butterfly plate is made of welded cobalt based alloy material, which has long wear resistance and service life; The large-sized butterfly board adopts a frame structure with high strength and low flow resistance. Some high-pressure models can withstand pressures of over 100MPa and are suitable for high-pressure gas environments.
actuator
Equipped with explosion-proof electric device for mining, with a protection level of IP67/IP68, supporting manual/automatic switching. The fully enclosed motor design ensures safe operation in dusty environments, with a built-in overheat protection switch to prevent motor damage.
