The atomizing de-dusting automatic regulating valve uses in the atomization mechanism system to be installed as shown in Figure 12.Require the water system of this device to guarantee hydraulic pressure 2～9kg/cm ², flow 27 liters/minute.This valve is installed on the basis between two running rollers of belt conveyor below, utilize the foot screw fixing hole (71) on the valve seat base plate to adjust the valve seat position, make driving wheel (1) be positioned at the center of belt width, guarantee that turning to of driving wheel (1) is consistent with the trend of belt.The belt natural height is as the criterion during with zero load, adjust the eccentric group (13) on the valve seat, make the distance between driving wheel (1) and belt keep about 2mm, eccentric group (13) is locked on axle (12) with stop pin (72), and meanwhile driving lever (70) has also just been finished the above-mentioned adjusted in concert to torsion spring (10) and spacing adjustment (adjusting) lever (21) under the eccentric control action of the single group of eccentric group (13) synchronously.Be connected with water source and nozzle with the water inlet (17) and the delivery port (18) of flexible pipe the atomizing de-dusting automatic regulating valve.

The utility model course of work is as follows, and it is mainly realized the open and close of water valve and regulates three work of corresponding aperture of water valve along with the variation of defeated coal load at any time.

When the coal conveyor belt does not have load and when dallying, leave the 2mm distance when installing between belt and driving wheel (1), driving wheel (1) does not rotate, and the atomizing de-dusting automatic regulating valve is not worked, and water valve is in closes the dress attitude.When on the coal conveyor belt load being arranged, when both being very little load, belt also can produce downward amount of deflection, and contact friction makes driving wheel (1) rotation, and gear oil pump (3) is started working shown in accompanying drawing 7,6.Make main valve body drive adjuster fuel tap body (59) simultaneously and move down, steel ball (63) closes closed pore (66), makes oil pump high pressure chest oil outlet (76) obstructed towards fuel feed hole (66) oil circuit of adjuster.Be inhaled into the oil of oil pump low pressure chamber by fuel feed hole (75) from shoe cream room (52), become after the high pressure through oil pump, can only enter the preceding pressure chamber of application cylinder piston (37) from oil outlet (77), the elastic force that promotion piston (37) overcomes plunger backer pressing spring (39), water valve spring (46) is moved to the left, promoting Inner part of water valve (45) opens, press water enters intake antrum by water inlet (17), filter the back through filter screen (48) and be sent to nozzle by drain chamber delivery port (18), atomizing de-dusting apparatus begins atomizing de-dusting work.

When the load on the coal conveyor belt increases, the amount of deflection of the sag of belt also increases, driving wheel (1) drives main valve body (2) and rotates around axle (11), adjuster fuel tap body (59) also moves down thereupon, and spacing adjustment (adjusting) lever is fixed on axle (11) and goes up motionless, the fuel tap core (62) that the fork plate of its end (22) limits adjuster also maintains static, so spring for governor (61) is compressed, pushing tow steel ball (63) continues sealing fuel feed hole (66), so leading to the oil circuit of adjuster fuel feed hole (66), the oil pump high pressure chest continues to close, the oil of oil pump high pressure chest continues to lead to application cylinder piston (37) from oil outlet (77), promote piston and continue out the aperture of big flood spool (45), so strengthened the output of atomizing de-dusting.

When the load on the coal conveyor belt reduces, the amount of deflection of the sag of belt also reduces, under torsion spring (10) tension force effect, main valve body (2) band driving wheel (1) is followed belt around axle (11) and is upwards rotated, adjuster fuel tap body (59) also moves up thereupon, and spacing adjustment (adjusting) lever (21) still is fixed on axle (11) and goes up motionless, the fuel tap core (62) that the fork plate of its end (22) also still limits adjuster maintains static, thereby spring for governor (61) weakens or loses control to steel ball (63), so the fuel feed hole (66) that is sealed by steel ball is opened, the pressure oil of oil pump high pressure chest reduces or no longer flows to application cylinder piston (37) from oil outlet (77), and flow to the application cylinder shoe cream room through adjuster fuel feed hole (66) from oil outlet (67) by oil outlet (76), piston (37) owing to reduced under the tension force effect that pressure oil acts on its back pressure spring (39) and water valve spring (46) moves right, the water valve core also moves right thereupon, reduced the aperture of water valve, so also just reduced the output of atomizing de-dusting.

When no load on the coal conveyor belt or when stopping operating, driving wheel (1), gear oil pump (3) quit work, application cylinder piston (37) loses the effect of pressure oil fully, acting in conjunction at its back pressure spring (39) and water valve spring (46) is pushed to the right side, water valve core (45) is also closed thereupon fully, so the water supply of atomizing de-dusting has also just stopped.

The utility model and present existing manually-operated water valve atomizing de-dusting and utilize the belt run action to convert the signal of telecommunication to and go control electromagnetic valve to carry out atomizing de-dusting relatively have lot of advantages.The common weak point of above-mentioned two kinds of methods is very easily to make belt ponding too much according to the size adjustment injection flow rate of dust, skidding accident occurs, but also it is too much to be directed at the bunker coal water content, increases energy consumption.The utility model has but overcome above-mentioned defective fully, not only can open and close automatically water valve, and can also according to how many automatic injection flow rates of regulating of carrying coal, and dust-laying effect is good; It is power that this device relies on the transmission belt leather of material conveying mechanism, does not need to provide in addition power source and other servicing units, and investment cost is few; This automatic regulating valve is arranged in gear oil pump, application cylinder, water valve and oil circuit adjuster etc. in the housing, compact conformation, simple, working stability reliable, it is easy to maintenance to use; Housing of the present utility model adopts the ZL103 material to cast, and gear oil pump is made with No. 45 steel modifier treatment, anticorrosive wear-resistant, and the valve body and valve seat of water valve and adjuster fuel tap all adopts the 2Cr13 material, so long service life; This automatic regulating valve can reach 30mm greatly around its central axis amplitude that swings up and down, and is therefore strong to the big compliance of convey materials quantitative change scope; This automatic regulating valve cuts out and opens the water valve movement response time and be not more than for 10 seconds along with loads change, thus it have highly sensitive, reaction is fast, adjusting function is good; In addition also have little, the lightweight characteristics of volume, whole valve body heavily has only 6 kilograms.
