The specific embodiment
With reference to accompanying drawing.The present invention includes closet 1, dirt box 2, described system also is provided with the vacuum extractor 3 of dirt box; Described system also is provided with water pressurizer 4, flush valve 5, described flush valve is the gas control two position three way directional control valve, described flush valve links to each other with the flooding nozzle 10 and the water source 6 of water pressurizer, closet respectively, described system be provided with by first solenoid directional control valve, 7 controlling parties to flush valve and water pressurizer pressurized air air feed loop 70; Described system is provided with defecation valve 8 between closet and dirt box, be provided with the working cylinder chamber 80 that drives its valve block 81 in the defecation valve, described system be provided with by second solenoid directional control valve, 9 controlling parties to pressurized air air feed loop, working cylinder chamber 90; Described system is provided with the admission line 101 that connects train compressed air gas source 100 and described first solenoid directional control valve and second solenoid directional control valve.Drawing reference numeral 102 is the pressure regulation filter on the admission line 101.The pressure regulation filter is the source of the gas processing element of total system usefulness gas, makes the solenoid directional control valve reliable operation and limits system works air pressure.
In Fig. 1 of the present invention, fine line is a control path, and tubular wire is a gas circuit, and heavy line is the water route.
In Fig. 1, drawing reference numeral 103 is a system controller, and system controller is a Programmable Logic Controller, such as computer, micro controller system or the like.
Described dirt box 2 is a negative-pressure container, and the dirt under closet row is temporarily stored at this, in the dirt box 2 liquid level switch that links to each other with controller can be set, and like this, can further guarantee the safe operation of system.Dirt box 2 is provided with heat-insulation layer and/or heat cycles pipeline, and dirt box 2 also is provided with the interface of suction dirt.
Described vacuum means is changed to the vacuum generator that utilizes the Venturi tube principle, as shown in Figure 2, it comprises main body 31, be provided with nozzle 32 in the main body, be provided with outside the head of nozzle and the cooresponding miscellaneous gas exhaust tube 33 of nozzle, described main body also is provided with the interface 34 of vacuum extractor and dirt box connecting line 35 at the nozzle place.Connecting line 35 is provided with non-return valve 36, and described vacuum generator is provided with and train compressed air gas source bonded assembly admission line 37, and described dirt box also is provided with moisture separator 21, and described connecting line 35 links to each other with moisture separator 21.
The connecting line of described vacuum extractor and dirt box is provided with multiple-connector 22, multiple-connector 22 is six pass joints in the present invention, described six pass joints connect connecting line that leads to dirt box and the connecting line that leads to vacuum extractor respectively, thereby form connecting line 35, described six pass joints also connect vac switch 23, blowdown valve 24, pressure switch 25 respectively, and another interface of described six pass joints connects compression indicator 26.
Described blowdown valve 24 prevents to produce malleation in the case and is provided with, and has unidirectional aeration.When producing malleation in the case, from then on air can discharge.
Above safety measure can make the present invention more safe and reliable.
Described water pressurizer comprises chamber 41, and described chamber is provided with and the air inlet/outlet 42 of flush valve pressurized air air feed circuit communication and the intake-outlet 43 that is communicated with flush valve, is provided with barrier film 44 between inherent described air inlet/outlet of described chamber and the intake-outlet.The native system flush valve commutates and resets and is gas control, and reset force is big, working stability.
For example, during use, when the people presses push button 104, at first, system controller is opened electromagnetic valve 38 to carry out vacuum pumping, simultaneously after time-delay 1.4 seconds, system controller sends instruction and makes first solenoid directional control valve, 7 energising commutations 2.9 seconds, pressurized air enters the barrier film top in the water pressurizer, pressurized air goes to port 2 from flush valve control port 1, make flush valve commutation, its result connects water pressurizer and disconnects the pipeline that the water source links to each other with water pressurizer with the nozzle on the closet, and the water in the water pressurizer washes away foul in the closet by the water high pressure flow nozzle in the rubber diaphragm promotion cavity of resorption under the compressed-air actuated pressure in barrier film top.After first solenoid directional control valve 7 was worked 0.6 second, system controller makes second solenoid directional control valve, 9 energising commutations 4 seconds, the other end that pressurized air flows into defecation valve working cylinder chamber 80 makes cylinder chamber air inlet commutation, valve block 81 in the defecation valve rotates, the connecting line 11 of closet and dirt is opened, the foul that just is being rinsed in the closet is inhaled into dirt box, finishes the once flushing circulation.Because the defecation valve is opened dirt box degree of vacuum is descended, vac switch passes to system controller with signal, and system controller is opened electromagnetic valve 38 makes vacuum generator carry out vacuum pumping, keeps degree of vacuum in the case, for next flush cycle is prepared.
System controller adopts Programmable Logic Controller.Incoming signal has liquid level signal and malleation signal, push button signal in vac switch signal, bleed pressure signal, the case, exports the time and the sequential of an electromagnetic valve of control and 2 solenoid directional control valves, when vacuumizing electromagnetic valve work, system controller starts 2 minutes time meters, if degree of vacuum in the dirt box was extracted into setting value will stops vacuum pumping and light overtime indicator lamp in 2 minutes.If the people is arranged by push button during vacuumizing, system controller will be remembered and vacuumize the circulation of end back execution once flushing.
