Description
Technical field
The utility model relates to the ventilator field, relates in particular to a kind of ventilator inlet flow rate controlling device.
Background technique
Ventilator can conveying gas and is improved gas pressure, is widely used in the industries such as mining, metallurgy, chemical industry, refrigeration, power and metallurgy of national economy.When work system needs gas flow to reduce, generally change the gas flow that enters work system by regulating the outlet valve opening.Such rate of discharge controlling device reduces rate of discharge because of increasing resistance to flow output, increase operating cost, the inlet flow rate controlling device changes flow by the gas flow that change enters in the ventilator, operating cost is low than the rate of discharge controlling device, thereby the inlet flow rate controlling device is used widely in the working site.
But existing ventilator inlet flow rate controlling device, its controlling mechanism by lead ring or rack tube on main drum outer wall, the power unit that drives lead ring or tooth bar is arranged on the outside of lead ring, tooth bar again, and the space that this structure is occupied is very big, is difficult under the situation of limited space at the scene use; And this class formation mostly is cantilever structure, blade outer end and all is exposed at outside the main drum outer wall outward, and blade that makes and main socket joint synapsis need sealing, and need to rotate because of blade, so sealing is difficulty relatively, when working medium is poisonous when being corrosive, seal not good can threat person poultry safety and befouling environment.There is shortcomings such as taking site space is big relatively, effect is low, cantilever structure, the difficult sealing of blade tip, the easy leakage of process gas in the existing inlet flow rate controlling device of this class.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ventilator inlet flow rate controlling device, and blade in this flow regulator and power unit all are built in the inner core, need not sealing, has improved safety in utilization when having reduced floor space.
The utility model is achieved in that a kind of ventilator inlet flow rate controlling device, comprise cylindrical shell, blade, petiole and oil hydraulic cylinder, described blade circumferentially is distributed in the cylindrical shell, blade is the symmetrical airfoil blade along main barrel dliameter to the cross section, this flow regulator also comprises inner core, it is coaxial with cylindrical shell that described inner core is fixedly mounted on inner barrel by sheet material, the flow path direction end profile of coming of inner core is a streamline, described oil hydraulic cylinder is installed in the inner core, have the location blind hole on the described cylinder inboard wall, described vane tip rotating shaft is arranged in the blind hole of location, fixedly connected with petiole in the blade bottom, described petiole is hinged on the inner core, and the bottom of petiole links to each other with oil hydraulic cylinder by slidercrank mechanism, and oil hydraulic cylinder links to each other with external oil pipe line.
Described blade and petiole are integrally formed as a whole.
Be provided with wearing ring between described vane tip rotating shaft and the location blind hole.
Be provided with inner core in the cylindrical shell of the utility model ventilator inlet flow rate controlling device, blade is by the Driven by Hydraulic Cylinder that is installed in the inner core, oil hydraulic cylinder drives the petiole rotation by crank during along axial-movement, change blade opening, regulate flow, the design of blind hole makes that whole cylindrical shell is the sealed whole body structure, poisonously also has the advantage that the site space of taking is little, effect is high when etching process gas is arranged can not revealing.
