The counterflow-preventing atomization mechanism that the utility model provides, when the blast of air intake during greater than the hydraulic pressure of water inlet blast valve plate can be washed open, valve plate rotates to the water inlet direction around coupling bar, be subject to stopping of backing pin and rest on the maximum open position when valve plate turns to backing pin place when place, this moment, valve plate can not seal water inlet, jointly enter valve inner through the current of water inlet with through the high pressure draught of air intake, behind nozzle, be vaporific; Valve plate can be closed with air intake under the impact of current and hydraulic pressure double action during less than hydraulic pressure when blast, can effectively prevent the problem of sealing adverse current, avoided the current adverse current Gas inlet tube that brings because blast is unstable, the reduction pneumatic equipment effect that causes affects the problem of construction environment.
Description of drawings
Fig. 1 is the structural representation of counterflow-preventing atomization mechanism of the present utility model.
The specific embodiment
As shown in Figure 1, the counterflow-preventing atomization mechanism that the utility model provides, this device comprises a valve body 1, this valve body 1 has air intake 11, water inlet 12 and the nozzle 13 that inside communicates with each other, has a valve plate 2 in the air intake 11, these valve plate 2 one ends 21 are articulated on water inlet 12 inwalls by coupling bar 4, and the other end 22 can cooperate with air intake 11 under from the External Force Acting of water inlet 12 directions and seal this air intake 11, have one on water inlet 12 inwalls and limit valve plate 2 openings of sizes backing pins 3.Backing pin 3 specifically can be a bearing pin or block, as long as can realize stoping valve plate 2 openings to continue to increase.Backing pin 3 specifically can be located at the valve plate top.Air intake and water inlet are circle, and valve plate also is circular, and when valve plate diameter during more than or equal to the water inlet internal diameter, the maximum open angle of valve plate is acute angle; When valve plate diameter during less than the water inlet internal diameter, the maximum open angle of valve plate can be the obtuse angle, prevent valve plate in overturning under the high pressure wind action can not be at self-closed air intake under the flow action on the water inlet inwall.
The counterflow-preventing atomization mechanism that the utility model provides, when the blast of air intake 11 during greater than the hydraulic pressure of water inlet 12 blast valve plate 2 can be washed open, valve plate 2 rotates to the water inlet direction around coupling bar 4, the maximum open angle of valve plate is acute angle, therefore be subject to stopping of backing pin 3 when backing pin 3 places are located and rest on the maximum open position when valve plate 2 turns to, this moment, valve plate 2 can not seal water inlet 12, jointly enter valve body 1 inside through the current of water inlet with through the high pressure draught of air intake, behind nozzle 13, be vaporific; When blast during less than hydraulic pressure valve plate 2 can under the impact of current and hydraulic pressure double action with air intake 12 closures, can effectively prevent the problem of sealing adverse current, avoided the current adverse current Gas inlet tube that brings because blast is unstable, the reduction pneumatic equipment effect that causes affects the problem of construction environment.
As the preferred embodiment of above-described embodiment, be equipped with the groove 7 for connecting pipe on the end of air intake 11, water inlet 12 and nozzle 13.The wall of groove is provided with at least two installing holes 6 that are used for wearing the connector that is fixedly connected with pipeline and valve body, the connector is here used the U-shaped card usually, also be provided with installing hole at pipe end to be connected, U-shaped card two ends penetrate the installing hole of being located at pipe end in the installing hole 6 of valve body junction, pipeline and valve body are fixed together.Have on the valve plate 2 be used to the sealing ring 5 that seals described air intake.Valve body 1 is specially a tee junction.Wherein tee junction center line two interfaces being 180 degree angles are respectively water inlet 12 and nozzle 13, and it is air intake 11 that center line and this water inlet 12 center lines or nozzle 13 center lines are 90 interfaces of spending angles, as shown in Figure 1.The maximum open angle of valve plate 2 is less than 90 degree.Valve plate 2 adopts the round iron sheet among this embodiment, and sealing ring 5 adopts rubber ring.
The specific works process is, water tube hose, wind flexible pipe, geomantic omen flexible pipe are linked to each other with threeway 1 by groove 7 respectively, water tube hose connects water inlet, the wind flexible pipe connects blast pipe, geomantic omen flexible pipe connection nozzle, and utilizes installing hole 6 by seal three junctions to be fixed.Keep the air intake of threeway 1 down, when blast during greater than hydraulic pressure distinguished and admirable meeting back down elastic tape and round iron sheet, simultaneously backing pin 3 generation effects control round iron sheet aperture is less than 90 °, this moment is distinguished and admirable mix with current wind power ganged; When blast during less than hydraulic pressure, the round iron sheet is closed under the effect of the impact of current and hydraulic pressure, close air intake, the anti-sealing of elastic tape infiltrates and plays sealing process, thereby realized the purpose of anti-sealing adverse current, avoided the current adverse current Gas inlet tube that brings because blast is unstable, the reduction pneumatic equipment effect that causes affects the problem of construction environment.
