Coal safety explosion-proof gas special valve with PTFE sealing and anti-static

1Coal safety explosion-proof gas special valve with PTFE sealing and anti-static：Overview

Coal safety explosion-proof gas special valve with PTFE sealing and anti-staticAdopting soft sealingStructure, widely used for medium temperature≤150℃The Governance of Gold Used for regulating flow and carrying fluids on industrial pipelines such as power, petrochemicals, water supply and drainage, and municipal construction.butterfly valveAdopting mining explosion-proof electric actuator with soft sealed flange butterfly valve,It has good corrosion resistance and long service life. This valve has bidirectional sealing function, and the product complies with national standardsGB/T13927-92Valve pressure test standard
IIElectric butterfly valve for gas pipeline:feature
1This valve adopts a three eccentric hard seal structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter as viewed.
2The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperature conditions,Has corrosion resistance,Long service life and other characteristics.
3The sealing surface of the disc plate is made of welded cobalt based hard alloy, which is wear-resistant and has a long service life.
4The large-sized butterfly plate adopts a frame structure with high strength, large overcurrent area, and low flow resistance.
5This valve has a bidirectional sealing function, which is not limited by the flow direction of the medium or the spatial position during installation, and can be installed in any direction.
6The driving device can have multiple workstations (rotating)90°or180°）Installation, easy for users to use.
IIIMining explosion-proof integrated electric butterfly valve： Characteristics of executing agencies
1、 housing-The shell is made of hard aluminum alloy, which has undergone anodizing treatment and polyester powder coating, with strong corrosion resistance and protection levelIP67Explosion proof ratingBT4And there areIP68andCT4for selection
2、 motor-Fully enclosed squirrel cage motor with small size, high torque, low inertia, and insulation level ofFGrade, built-in overheat protection switch, can prevent motor damage caused by overheating.
3、 Manual structure-The guarantee case of the handwheel is reliable, labor-saving, small in size, and can be manually operated by pulling the clutch handle when not powered. When powered on, the clutch automatically resets. (Note):When the motor is not powered, the electric actuator will remain in manual mode
4、 indicator-The indicator is installed on the central axis to observe the position of the valve. The lens adopts a convex lens, which does not accumulate water and is easy to observe.
5、 dryer-Used to control temperature, prevent moisture condensation inside the actuator due to temperature and weather changes, and keep the internal electrical components dry.
6、 limit switch-Mechanical and electronic dual limit. The mechanical limit screw is adjustable, and the case is reliable; The electronic limit switch is controlled by a cam mechanism, and a simple adjustment mechanism can accurately and conveniently set the position without the need for battery support (the micro switch contacts are uniformly silver contacts)
7、 Torque switch-It can provide overload protection, automatically disconnect the motor power supply when the valve is stuck or there are foreign objects, and more effectively protect the valve and electric actuator from damage. (It has been set before leaving the factory, please do not change the settings arbitrarily)
8、 self-locking-The precision and double worm gear mechanism can efficiently transmit large torque, with high efficiency and low noise (* large)50Decibel level, with a long lifespan and self-locking function to prevent reverse rotation, the transmission part is stable and reliable. It has been filled with high-efficiency lubricating grease before leaving the factory and does not need to be refilled for use.
9、 Anti loosening bolt-When dismantling the shell, the bolts are attached to the shell and will not fall off. All external bolts are made of stainless steel material.
