Embodiment
More obviously, hereafter can will coordinate appended diagram, be described in detail below to allow above and other object of the present utility model, feature and advantage.
Fig. 2 is the exhauster structure schematic diagram that the utility model provides.As shown in Figure 2, the venting gas appliance of the mist eliminator flushing water valve that the utility model provides comprises: cylinder 2, in described cylinder 2 motion with promote valve 3 piston 1, for the upper pipeline 7 of air inlet and exhaust and lower pipeline 8 and the solenoid directional control valve 6 passing in and out described cylinder 2 for controlling gas from pipeline 7 described and lower pipeline 8, this device also comprises: modulating valve, be positioned at the exhaust ports of described lower pipeline 8 and/or upper pipeline 7, for the flow that adjustments of gas is discharged in described cylinder 2.The utility model, by the outlet valve in venting gas appliance is replaced by modulating valve, can regulate the flow of gas, thus slows down the movement velocity of the piston promoting valve, solves the problem because the inner line with rubber in too fast the caused absorption tower of valve event washes out.
Wherein, described modulating valve can comprise: valve seat; Spool; And knob, for the gap length between regulating valve seat and spool, with the gas flow of control flow check through this gap.
Wherein, described modulating valve comprises: lower pipeline modulating valve 4 and upper pipeline modulating valve 9, lay respectively at the exhaust ports of described lower pipeline 8 and upper pipeline 7, for the flow that adjustments of gas is discharged in described cylinder 2.
Described solenoid directional control valve 6 is two-position five-way solenoid directional control valve, and its working principle is as follows:
Transform electrical signals is pneumatic signal by electricity Transformation cassette, the pneumatic output of pneumatic signal input control.The most frequently used electric Transformation cassette is solenoid valve.Solenoid valve is the interface of electrical control part and pneumatic do-part, is also the interface of air supply system simultaneously.Solenoid valve takes orders release, stops or changing the flow direction of cylinder compressed air.In pneumatic circuit, the effect of solenoid directional control valve is the break-make of control air-flow path or changes compressed-air actuated flow direction.For the solenoid directional control valve 6 in the venting gas appliance that the utility model provides, when mist eliminator flushing water valve cuts out, solenoid directional control valve 6 cuts out the relief opening of lower pipeline 8 by jettron, open the suction port of lower pipeline 8, open the relief opening of pipeline 7, and close and close the suction port of pipeline 7, thus the gas realizing flowing into from wind regime 5 enters cylinder from lower pipeline 8, and this gas push piston 1 move upward period from pipeline 7 discharge in cylinder the gas being positioned at upper piston area.When mist eliminator flushing water valve is opened, solenoid directional control valve 6 opens the relief opening of lower pipeline 8 by jettron, close the suction port of lower pipeline 8, close the relief opening closing pipeline 7, and open the suction port of pipeline 7, thus the gas realizing flowing into from wind regime 5 enters cylinder from upper pipeline 7, and discharge in cylinder from lower pipeline 8 gas being positioned at piston lower portion during this gas push piston 1 moves downward.Main operational principle is the effect of the electromagnetic force utilizing electromagnetic coil to produce, and the spool promoting solenoid directional control valve switches, and realizes the commutation of air-flow.By the difference of Electromagnetic Control part to the selector valve way of propelling, direct driving type electromagnetic selector valve and magnetic exchange valve of leading type can be divided into.Direct driving type electromagnetic selector valve directly utilizes electromagnetic force to promote spool commutation, and guide's air pressure that magnetic exchange valve of leading type then utilizes electromagnetic priority valve to export promotes spool commutation.During coil electricity, static iron core produces electromagnetic force, and make pilot valve action, pressurized air enters solenoid directional control valve guide piston by gas circuit makes piston start, and in the middle of piston, sealing disc opens passage.When power is off, pilot valve resets under the action of the spring, returns to original state.Solenoid directional control valve in the venting gas appliance that the utility model provides can adopt direct driving type electromagnetic selector valve, directly utilizes electromagnetic force to promote spool commutation.
