Dense Phase Pneumatic Conveying System Dome Valve With Automatic Control

Product Specification

  Pneumatic dome valve,Its material is 45 and Q235,used for the Pneumatic Conveying System:

  Pneumatic dome valve is a new type of quick closing valves, it is the strength of coal ash conveying system used in the largest number and the best valve. Mainly used in electric power, metallurgy, chemical, food, pharmaceutical and other fields in the pneumatic conveying system of dry ash, powder material feeding port, ourtlet, vent, air blend, row of taphole and pipeline switch control switch. Product with good performance in market for many years and wins the general customers trust.

  Opening and closing flexible, no flush. Dome valve core and the special rubber sealing ring keep 0.8 ~ 1.5 mm clearance, valve core movement with sealing ring out of contact, small resistance, flexible rotation, and reliable running, sealing ring of long service time; When the valve opens, mouth full circulation without stop, avoid the material directly scour of valve core.

  Sealed tightly, good performance of dome valve sealing adopts special inflatable rubber sealing ring, sealing is good. When the dome valve closed, rubber seal aeration, expansion, wrapped tightly on the spherical valve core, forming a very reliable sealing ring band, sealed tight, thereby effectively blocking the flow of the material in the pipeline.

  Well-selected materials, process science. The dome valve core components according to the different kinds of working condition in different wear-resisting material, make the product wear-resisting, scour resistance and other characteristics; Valve core is smooth and hard surface, to ensure the valve core is close contact with the rubber sealing ring, achieve the best sealing configuration.

  Automatic control, reliable operation. The dome valve pneumatic actuator driven by closed rotary pusher-type straight cylinder, rotary output, reliable performance, large output torque,it can meet the working in harsh operating conditions.

  The dense phase pneumatic conveying system is applicable to the conveying of powder material as dry ash, cement, and industrial chemicals. It is a high efficiency, zero pollution conveying system, widely used in the material conveying in industry of power plant, building materials, and chemicals.

  Because the air consumption is low and the material-air ratio is high, the material will have shunting movement in the pipe, achieving dynamic and static pressure conveying. Therefore, the flowing speed of the material is slow, the abrasion of the valve and pipeline is low, and the service life of the wearing part is long.

  It has primary and secondary inlet air adjusting methods, which makes the system work under the best air consumption ratio condition and the best fluidizing state.

  The unblocking system adopts the unique positive pressure back suction unblocking principle, having the characteristics as low air consumption and reliable unblocking. It only needs to lead the material-air mixture going through the unblocking valve and pipeline to the material hopper or inlet of air flue, do not need set additional blowing element along the pass, construction is simple and operation is easy.
