Bell pneumatic valve structure principle

bell pneumatic valve is mainly used for high temperature dust gas switch pneumatic valve, and blast furnace gas generator used more common, there are dry and wet type two kinds. With compact structure, cover an area of an area small, air tightness, high reliability, etc. Bell pneumatic valve principle is very simple, the upper is a tubular or tapered bell, bell rod connected to the upper activities, bottom as the air inlet, clock cover down to lower air inlet, and vice and pneumatic valve opens, the export Settings on the side.
overview of bell jar pneumatic valve:
has compact structure, cover an area of an area small, tightness, high reliability, yan made significant improvements in the drive device, in particular, from stationary open/close to simultaneous opening and closing. Increase the runner, ensure that the open shut down of the pneumatic valve plate are always keep axis vertical movement, so as to improve the service life of the wire, reduce the fault. The operation of the pneumatic valve disc set made guide system to make it smooth operation, corrosion resistance, abrasion resistance, compression of nickel base alloy seal, use wire seal, ruled out the media's influence on the sealing performance, enhance the reliability of the sealing and pressure resistance.
bell pneumatic valve structure principle:
is mainly composed of drive synchronous operation, support, barrel, guide rod, and pneumatic valve, pneumatic valve plate, limit of specialized, the escalator. For its operation principle, when drive electric rotary motion, enhance the wire drive the guide bar, through the guide bar connection; Shaft to pneumatic valve plate movement transmission, allowing for the movement of pneumatic valve, achieve the goal of open. Whereas drive reverse the pneumatic valve plate of falling off. In the drive to start at the same time, synchronizer to start at the same time, promote make linear synchronous drive forward or backward, to ensure that the pneumatic valve opening and closing movement of vertical center.
bell pneumatic valve structure of the product features:
bell pneumatic valve has good sealing performance, long service life, action quick, reliable work, open/close accurate positioning and open-close torque is little, sealing ring resistance loss, and a sealing ring automatic compensation function, at the same time can be used with different combination of the actuator, achieve the goal of far moment away from centralized control, widely used in the pulverized coal and the coal pulverizing system.
