Shut- off gates, pneumatic
Serie 42
Idencification – SUP
Type of construction – pneumatic
CHARACTERISTICS AND APPLICATION :
Shut of gates are intended for an operational and emergency cutting-off of the flow of material from hopper-outlet, silos, chute and similar equipment. They are not specified to regulation of material-flow volume. They are suitable to wide range of bulk, dry, powdered and granular materials with grain size within the range 0 – 32 mm, in technological production lines of cement, lime, ground raw materials, aggregates of stones and similar products. The shut-off gates with pneumatic cylinder are used for a high percent occurrence of manipulations and for remote control-possibility.
DIMENSIONS AND PARAMETERS :
Type range of shut-off gates SUP include 7 sizes < from 160 x 160 mm to 650 x 650 mm > ( s. table – project data sheet ). After technical-business discussion it is possible to order except these sizes a special modification. A special type of construction has to be agreed at technical-business discussion. Operating is done through pneumatic cylinder ¨ 63–150 mm by working air pressure 0,6 MPa. Default shut-off gates have pneumatic components from prestigious firms acc. to supplier´s design or acc. to agreement of customer.
DESCRIPTION OF CONSTRUCTION :
Shut-off gate has usually square section, by atypical design it has a rectangular section (clear opening). These sections are closed through plate-slide which is operated with pneumatic cylinder (by SUP). Components of delivery are manually or remote-controlled ditributors and valves. The shut-off gate frame is welded from U – steel section. The plate-slide, which ist into the frame inserted, is supported through cylindrical boltheads. At bigger sizes the plate-slide is supported through longitudinal support (in axis). Sheet of the plate-slide is sealed on the outlet from clear opening through adjustable packing. The clear opening is sealed between sheet and frame through packing cord (all over the circumference). The packing and sheet edges are protected through steel-squareends.
Design of individual products is conditioned by physical properties of materials, for which they´re specified. Shutting sheets are manufactured from steel class 11 or 17 acc. to CZ-Standard ČSN. For raw materials and products with temperature to 200°C we use seal profiles from special materials. Seating face of the plate-slide is solved otherwise by granular materials as by powdered materials.
A special type of construction and special requirements must be consulted with supplier !!!
