Background technology
At present, for environmental protection and water-saving consideration, the research of domestic beginning vacuum closet and supply and drain water system thereof, but still do not have condition of production report.Multiple schemes such as that the control mode of external vacuum closet bath, blowdown has is automatically controlled, high pressure gas control, vacuum gas control, even implement control by microprocessor, cause system architecture complexity, fetch long price, maintenance difficult.
Summary of the invention
The object of the present invention is to provide a kind of water supply and drainage system for vacuum toilet, by bath, the blowdown control of Pneumatic reversal valve realization system, simplify control procedure, simplied system structure reduces cost.
A kind of water supply and drainage system for vacuum toilet of the present invention, by Pneumatic reversal valve, the vacuum Time-delay water valve, device drenches with rain, closet, vacuum interface valve constitutes, the import of vacuum Time-delay water valve is by pipeline UNICOM running water system, outlet is through the pipeline UNICOM device that drenches with rain, the device that drenches with rain is placed in the closet, the vacuum interface valve import of closet blowdown channel UNICOM, the vacuum interface valve outlet port is through pipeline UNICOM vacuum source, Pneumatic reversal valve can be two-position five-way valve, and a through hole is through pipeline UNICOM vacuum Time-delay water valve air control hole on its valve body, a through hole is through pipeline UNICOM vacuum interface valve air control hole, the logical atmosphere of through hole, remaining two through hole is through pipeline UNICOM vacuum source.
Described water supply and drainage system for vacuum toilet, two through holes of described Pneumatic reversal valve valve body can be through pipeline order UNICOM vacuum air storage tank, one way valve, UNICOM's vacuum source again.
Described water supply and drainage system for vacuum toilet, it is further characterized in that the through hole that seals on the valve body when described Pneumatic reversal valve is in static station is through pipeline UNICOM vacuum Time-delay water valve air control hole, when described Pneumatic reversal valve is in work station, the through hole that seals on the valve position is communicated with atmosphere, the through hole of connecting with open to atmosphere through hole in the valve body when being in static station is through pipeline UNICOM vacuum interface valve air control hole, and remaining two through hole is through pipeline UNICOM vacuum source on the valve body.
Described water supply and drainage system for vacuum toilet, it further is characterised in that between vacuum Time-delay water valve import described in this system and the running water system switch is set, between this system and the vacuum source vaccum stop valve is set.
Water supply and drainage system for vacuum toilet provided by the present invention, its compact conformation, simple is through test of many times, the correct control that the energy realization is taken out just, washed by water vacuum closet is easy to connection is installed, and is cheap compared with other control mode expense, filth-discharging effect is good, and water-saving result is remarkable.

The specific embodiment
As shown in Figure 1, this system comprises vacuum air storage tank 1, Pneumatic reversal valve 2, vacuum Time-delay water valve 3, the device 4 that drenches with rain, closet 5, vacuum interface valve 6, one way valve 8 and each unicom pipeline, when system is in static station, vacuum Time-delay water valve air control hole 3a is closed by Pneumatic reversal valve 2, water valve is not opened, vacuum interface valve air control hole 6a communicates with atmosphere by Pneumatic reversal valve 2, and interface valve is not opened.When needing blowdown, press Pneumatic reversal valve 2 buttons, state becomes work station as shown in Figure 2, and promptly vacuum Time-delay water valve 3 air control hole 3a are communicated with vacuum source, and the water valve inner carrier moves down, and water valve is opened, and tap water flows into the device 4 that drenches with rain through water valve and dashes just; Vacuum interface valve 6 air control hole 6a also connect with vacuum source, and interface valve 6 is opened, and the dirt in the closet 5 sucks vacuum pipe through interface valve 6.Release button recovers static station shown in Figure 1, and vacuum interface valve 6 is closed, and vacuum Time-delay water valve 3 is pressed setting-up time, closes after generally delaying time 2～3 seconds, stops to supply water.
The effect of vacuum air storage tank 1 is to play the moment regulating action when huge numbers of families use vacuum closet simultaneously, the interim problem that occurs when the vacuum source negative pressure is not enough when avoiding load summit.The one way valve 8 air source negative pressure of only taking seriously is open-minded when being higher than the negative pressure of vacuum air storage tank, guarantees that vacuum air storage tank remains subatmospheric negative pressure value, simultaneously, prevents that also the dirt that vacuum interface valve 6 is discharged from entering Pneumatic reversal valve 2 through vacuum air storage tank 1.
When system of the present invention and running water system and vacuum source UNICOM, switch 9 and vaccum stop valve 7 can be set.Switch 9 is used for system and running water system are disconnected.Vaccum stop valve 7 can be used as the vacuum source switch of each user terminal, can turn-off vacuum source at system maintenance or when changeing, and disconnects with total pipe network.
Fig. 3 and Fig. 4 represent a kind of Pneumatic reversal valve, 11 is button, have annular groove 12a and 12b on the spool 12, the through hole 13a of valve body 13 leads to atmosphere, through hole 13b, 13e connect vacuum source, and through hole 13c connects the vacuum Time-delay water valve, and through hole 13d connects vacuum interface valve, 14 is back-moving spring, and valve bottom 15 has open to atmosphere hole 15a.16 is seal washer.During as shown in Figure 3 static station, the through hole 13d that connects vacuum interface valve connects through hole 13a through the annular groove 12a of spool 12 and is communicated with atmosphere, and the through hole 13c of UNICOM's vacuum Time-delay water valve seals.Press the button 11 as shown in Figure 4 during work station, spool 12 moves down, and annular groove 12a connects through hole 13d and 13b, and annular groove 12b connects through hole 13c and 13e, thereby vacuum Time-delay water valve, vacuum interface valve are all connected vacuum source and opened.
At work, having a spot of water enters in the Pneumatic reversal valve 2 through the air control hole 3a of vacuum Time-delay water valve 3, enter vacuum pipe through tracheae again, the material that therefore constitutes Pneumatic reversal valve is answered water-fast corrosion, can adopt engineering plastics, stainless steel, pottery or brass.
