Abstract
The utility model relates to an air quantity regulating valve for a dust-cleaning system. The utility model has the technical scheme that a fixed perforated plate [3] and a movable perforated plate [2] which are mutually and closely contacted are arranged on an inlet of a valve body [1]; the fixed perforated plate [3] and the valve body [1] are fixedly connected; a flow guiding plate [4] is welded on the middle part of a hole bridge on one side of the fixed porous plate [3]; the outer side of the valve body [1] is provided with a regulating supporter [9], and a regulating screw [6] is movably matched and arranged in the regulating supporter [9]; one end of the regulating screw [6] is connected with a regulating handle [8], and a nut [5] on the other end of the regulating screw [6] is fixedly connected with the movable porous plate [2]. The shape, the size, the number and the layout of the fixed perforated plate [3] and the movable perforated plate [2] are same. The shapes of the holes of the fixed perforated plate [3] and the movable perforated plate [2] are rectangular or circular. The utility model has the characteristics of simple structure, uniform air flow distribution, favorable abrasive resistance and low cost. The service life of the utility model is three to five times of a common air quantity regulating valve.
Description
One, technical field
The utility model belongs to a kind of volume adjusting apparatus.Relate in particular to a kind of dust pelletizing system volume damper.
Two, background technology
Be the resistance and the adjusting air quantity of balance dedusting pipe network, in dust pelletizing system, extensively adopt throttle pipe and volume damper at present.Though throttle pipe can be used for the resistance of balance pipe network effectively, also exists bigger limitation: the one, the throttle pipe percent opening is unadjustable, and the 2nd, the high velocity air of throttle pipe outlet will cause the pipe fitting wearing and tearing aggravation of back.
Also common actual air volume control valve is regulated the air quantity of branched pipe and dust sucting point in dust pelletizing system, and the volume damper that is applied at present in the dust pelletizing system mainly contains push-pull valve and dish valve.If the concentration of dust is big in the air-flow, abrasiveness strong, when the aperture of volume damper is smaller again, it is exactly that valve body, spool very easily wear and tear that push-pull valve and dish valve all exist a common shortcoming, and straight pipeline thereafter all exists serious wear phenomenon even.Main cause is because valve arrangement is unreasonable, rapid variation has taken place in the flow field when causing dust-contained airflow to pass through control valve, the air-flow secundly, and dust is under action of centrifugal force, almost all with the valve body friction that bumps, thereby cause the wearing and tearing aggravation of dust to control valve and pipe fitting.
Three, summary of the invention
Task of the present utility model provides a kind of simple and reasonable, air-flow is evenly distributed, anti-wear performance is good, prolong service life, cost is low volume damper.
For realizing above-mentioned task, the technical scheme that the utility model adopted is: fixedly porous plate and the active multi-hole plate of being close to mutually is installed in the porch of valve body, fixedly porous plate is fixedlyed connected with valve body, deflector is welded on the fixedly middle place of bridge of porous plate one side, arranged outside at valve body has the adjusting support, adjusting screw(rod) is installed in movingly to be regulated in the support, and adjusting screw(rod) one end is connected with regulating handle, and the nut of the adjusting screw(rod) other end is fixedlyed connected with active multi-hole plate.
Wherein, fixedly the shape in the hole of porous plate and active multi-hole plate, size, quantity, layout are just the same.The fixing hole shape of porous plate and active multi-hole plate or be rectangle or for round.
Fixedly the place all is welded with deflector in the middle of the bridge of each rectangular opening of porous plate one side or each row circular port.Deflector [4] is rectangular opening width or circular port diameter 3～6 times along the length of airflow direction.
Because adopt technique scheme, the utility model can be avoided the wearing and tearing of high speed dust-contained airflow to valve body and valve rear tubular member, and dust concentration is more even along the distribution of valve body section, has significantly reduced the dust number that the cutting collision takes place with valve body.Thereby the wearing and tearing of dust have been alleviated to valve body.So the utlity model has characteristics simple and reasonable, that air-flow is evenly distributed, anti-wear performance is good, cost is low, be 3～5 times of general volume damper service life.
Four, description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Five, the specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Present embodiment as shown in Figure 1, fixedly porous plate [3] and the active multi-hole plate of being close to mutually [2] is installed in the porch of valve body [1], fixedly porous plate [3] is fixedlyed connected with valve body [1], deflector [4] is welded on the fixedly middle place of bridge of porous plate [3] one sides, arranged outside at valve body [1] has adjusting support [9], adjusting screw(rod) [6] is installed in movingly to be regulated in the support [9], adjusting screw(rod) [6] one ends are connected with regulating handle [8], and the nut [5] of adjusting screw(rod) [6] other end is fixedlyed connected with active multi-hole plate [2].
Wherein, fixedly the pass of porous plate [3] and active multi-hole plate [2] is a rectangle, and the quantity and the layout in its pass size, hole are just the same; Deflector [4] is fixedly connected on the fixedly middle place of bridge of each rectangular opening of porous plate [3]; Deflector [4] is 5 times of rectangular opening width along the length of airflow direction.
The using method of this control valve is: when the aperture maximum of the rectangular opening of active multi-hole plate [2] valve when fixedly the rectangular opening of porous plate [3] overlaps fully, by rotating regulating handle [8], adjusting screw(rod) [6] can drive active multi-hole plate [2] and move right, thereby the aperture of adjustable valve, the big I of aperture shows by indicator of opening [7].
This control valve can be avoided the wearing and tearing of high speed dust-contained airflow to valve body and valve rear tubular member effectively, and dust concentration is more even along the distribution of valve body section, has significantly reduced the dust number that the cutting collision takes place with valve body, thereby has alleviated the wearing and tearing of dust to valve body.
