Purpose of design of the present utility model can also reach by following measure:
Its pneumatic air water mixing valve adopts by two air water mixing valves that air-operated diaphragm valve is combined integrated.
Above-mentioned by two air water mixing valves 5 that air-operated diaphragm valve is combined integrated, valve body 10 is arranged, one end of valve body 10 has compressed air source inlet P1, pressure water source inlet P2, the other end has air water mixture export P0, two middle side parts of valve body 10 respectively have the boss of a band centre bore, cavity around the boss is interconnected and constitutes hybrid chamber 11, two boss cooperate with diaphragm 8,13, form work valve port A, B at the center port place, valve gap 9,12 compresses diaphragm 8,13 peripheries, and constitute control chambers 7,14 with diaphragm 8,13, control air pressure inlet K is arranged on the valve gap 9,12.
Its motor-driven outlet valve, the valve seat 19 that is connected one with air bag 2 is arranged, relief hole 18 is arranged on the valve seat 19, valve rod 15 is arranged in the relief hole 18, relief hole 18 1 sides are led to atmosphere, opposite side and are contacted with valve block 20 on the valve rod 15, and have back-moving spring 21 to compress, and valve rod 15 is by inside and outside fairlead 22,16 location and guiding, and valve rod 15 outer ends are the force side that receiving sensor triggers the power effect.
Its choke valve adopts hand to grasp the flow regulating valve 3 that declines.
The utility model compared with prior art has following advantage:
1. only be power source, can realize power free auto spraying easily, avoided employing electrical explosion proof structure, reduced cost with compressed air.
2. this device only adopts air bag and air water mixing valve of a band outlet valve, and overall structure is simple especially; And reliable operation, processing is simple.In addition, adopt the air water hybrid mode, atomizing effect is good.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a gas control schematic diagram of the present utility model.
Fig. 2 is the structural representation of the air water mixing valve of the utility model embodiment.
Fig. 3 is the structural representation of motor-driven outlet valve of the air bag of the utility model embodiment.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 shows gas control schematic diagram of the present utility model.Among the figure, compressed air source directly is communicated with air water mixing valve 5 inlet P1, P2 separately with pressure water source, and shower nozzle 6 connects the mixture export P0 of air water mixing valve 5.Compressed air is communicated with air bag 2 through filter 4, choke valve 3, and air bag 2 directly communicates with the control chamber of air water mixing valve 5.One side of air bag 2 is provided with motor-driven outlet valve 1, and in the outlet valve 1 one sides ventilation capsule 2, opposite side leads to atmosphere, and the effect of sensor-triggered power is accepted in the valve rod outer end of motor-driven outlet valve 1.During original state, contain compressed air in the air bag 2, when the site environment variation needs atomizing de-dusting, sensor produces triggering power F, touches outlet valve 1 and opens, and air bag 2 compressed airs are discharged rapidly, the pressure of air water mixing valve 5 control chambers reduces, valve position conversion, compressed air and water are after the hybrid chamber 11 of air water mixing valve 5 mixes, and being atomized by shower nozzle 6 sprays.Simultaneously, compressed air is grasped the flow regulating valve 3 that declines through filter 4, hand and is slowly injected air bags 2, and after time-delay a period of time, air bag 2 internal pressures are recovered, and the control chamber pressure of air water mixing valve 5 recovers synchronously, and mixing valve 5 cuts out, and spraying stops.All the other control air pressure inlet k, throttling air source inlet P ' 1 in addition.
Fig. 2 shows the structure of its pneumatic air water mixing valve 5.Among the figure, respectively there is the boss of a band centre bore at the middle part of valve body 10 both sides, and two centre bores are communicated with compressed air source inlet P1 and the pressure water source inlet P2 that is positioned at air water mixing valve 5 one ends respectively.Two boss cooperate with left and right diaphragm 8,13 respectively, form left and right work valve port A, B at the center port place, cavity around the boss of two ends is interconnected, and constitutes hybrid chamber 11, and hybrid chamber 11 has the mixture export P0 that is positioned at air water mixing valve 5 other ends, leads to shower nozzle.Left and right valve gap 9,12 usefulness bolts and valve body 10 combines as a whole, and compress respectively left and right diaphragm 8,13 periphery, and constitute left and right control chamber 7,14 with left and right diaphragm 8,13 respectively.One control air pressure inlet k is respectively arranged on the left and right valve gap 9,12.Original state has the control air pressure from air bag 2 in the left and right control chamber 7,14, gross area acts on the left and right diaphragm 8,13, and diaphragm 8,13 pressurized sealing work valve port A, B make mixing valve 5 place's closed conditions; In case control air pressure diminishes, separately work valve port A, B are opened in the effect of air source and pressure water source by compression respectively of left and right diaphragm 8,13 respectively, and air water injects hybrid chamber 11, exports through mixture export P0.
Fig. 3 shows the structure of the motor-driven outlet valve 1 of air bag 2.Motor-driven outlet valve 1 is positioned at a side of air bag 2, and its valve seat 19 is connected as a single entity with air bag 2 walls, and the boss of a band relief hole 18 is arranged on the valve seat 19, and relief hole 18 1 sides are led to atmosphere, and its opposite side and valve block 20 cooperatively interact, and constitute the valve port of gas path on-off.Valve rod 15 is housed in the relief hole 18, the outer end of valve rod 15 has force rod 17, and force rod 17 can change on pattern, as arc ram, roller type etc., accept the effect that multiple sensing triggers power F, as the triggering power of the baffle plate of tunnelling blasting impact ripple, the triggering power of kick-up running etc.When external environment change to produce triggering power F, force rod 17 promoted valve rods 15, and valve rod 15 slides inside and outside fairlead 22,16 in, simultaneously, valve block 20 boss of lifting off a seat, the compressed air in the air bag 2 pass through relief hole 18 pressure releases release.Motor-driven outlet valve 1 inboard, valve rod 15 rear portions are with back-moving spring 21, disappear when the external world triggers power F, and back-moving spring 21 compressing valve blocks 20 are closed relief hole 18, and the air bag of sealing begins the compressed air supplementary pressure by throttling air source inlet P ' 1.
