The switching principle of the switching principle of the switching principle of main valve of the present invention and secondary valve and common water intaking valve or common electromagnetic valve is identical, all is that the epicoele of the relief hole control spool that covers by open and close valve and the pressure differential of cavity of resorption reach open and close valve; When current being arranged through out-of-date, the relief hole shut off valve on the valve gap just is closed, and the relief hole opening valve on the valve gap just is unlocked, and is specific as follows:
Place spool in the valve body, spool has the hole of up/down perforation, spool is divided into epicoele and cavity of resorption with valve inner, cavity of resorption comprises intake antrum and water chamber, the valve body epicoele communicates with cavity of resorption by the aperture on the spool, when relief hole is in closed condition and has current to enter, part water reaches the valve body epicoele by the aperture on the spool, this moment, spool was subject to the downward applied pressure of water in the epicoele and the water in the intake antrum applied pressure that makes progress, downward pressure size multiply by the cross section of epicoele for hydraulic pressure, be the cross section of spool, the size that upwards pressure multiply by the cross section of intake antrum for hydraulic pressure, owing to hydraulic pressure is the same, and the cross section of intake antrum is much smaller than the cross section of epicoele, therefore the downward pressure that is subject to of spool is greater than upwarding pressure, and spool is in lower shifting state, cuts off the connection of intake antrum and water chamber.This state is called the closed condition of this valve body.
When relief hole is in opening, the valve body epicoele communicates with the external world by relief hole, because the hole diameter on the spool is less than the diameter of relief hole on the valve gap, when current enter, reach by the aperture on the spool that the water of valve body epicoele is very fast to go out valve body by letting out little pressure orifice flow, the downward pressure that spool is subject to is less than upwarding pressure that it is subject to, when arriving a certain pressure differential, spool is in raised state, and intake antrum is communicated with water chamber, and current flow into water chamber from intake antrum.This state is called the opening of this valve body.
In summary it can be seen that when current passed through, relief hole was closed and then caused valve to be closed, relief hole is opened and is then caused valve to be opened.Therefore, control the switching of relief hole, just controlled the switching of valve, thus the outflow of control current.
Workflow of the present invention is as follows:
A. water saving fixtures of the present invention are fixedly mounted in the water tank, make the lower end of water inlet pipe and playpipe outside water tank, water inlet pipe is connected with external water source, and connecting hose on the playpipe, another termination of described flexible pipe are in the middle part of bedpan or bottom bottom or the blow-off line entrance.This moment is anhydrous in the water tank, and main valve buoyancy aid mechanism and secondary valve buoyancy aid mechanism do not float.
When main valve buoyancy aid mechanism does not float, the jointing that is connected with main valve buoyancy aid mechanism on the main valve cursor is the decline state, because the resilient plug of the main valve valve gap relief hole of main valve cursor top and jointing are in the both sides of rotating fulcrum, therefore the resilient plug on the main valve cursor is propradation, and the main valve relief hole is open mode.
When secondary valve buoyancy aid mechanism does not float, the jointing that is connected with secondary valve buoyancy aid mechanism on the secondary valve cursor is the decline state, because the resilient plug of the secondary valve valve gap relief hole top of secondary valve cursor and jointing are at the homonymy of rotating fulcrum, therefore the resilient plug on the secondary valve cursor is the decline state, and secondary valve relief hole is closed condition.
B. open external water source, current enter the intake antrum of main valve from water inlet pipe because the main valve relief hole is open mode, when current by the time, main valve is opened, main valve intake antrum and water chamber are connected; Current successively by main valve intake antrum, main valve water chamber, enter secondary valve intake antrum; Or current successively by main valve intake antrum, main valve water chamber, anti-siphon valve intake antrum, anti-siphon valve water chamber, enter secondary valve intake antrum; Because secondary valve relief hole is closed condition, valve core of auxiliary valve is in lower shifting state, and secondary valve intake antrum and water chamber are not communicated with, current by being positioned at main valve water chamber and the delivery port on the passage that is connected of the intake antrum of secondary valve enter water tank.
C. after external water source continues to flow into a period of time, rise in the Water in Water Tanks position, because main valve buoyancy aid tank energy different with the water inlet structure of secondary valve buoyancy aid tank so that main valve buoyancy aid mechanism at first float, the jointing that is connected with main valve buoyancy aid mechanism on the main valve cursor rises, the resilient plug of the main valve valve gap top on the main valve cursor descends, and the main valve relief hole is closed, and main valve is closed, intake antrum and the water chamber of main valve are not communicated with, and stop to the water supply of water tank.
D. after main valve is closed, pair valve buoyancy aid mechanism floats, driving on the secondary valve cursor jointing that is connected with secondary valve buoyancy aid mechanism rises, thereby the resilient plug of the secondary valve valve gap top on the secondary valve cursor is also risen, the relief hole of secondary valve is opened, so but since this moment main valve closed and do not have current to pass through, secondary valve is in a kind of state to be opened.
E. water tank opening water discharge, water level descends in the water tank, because the one way valve of main valve buoyancy aid tank bottom is different from the one way valve opening degree of secondary valve buoyancy aid tank bottom during water outlet the water yield of main valve buoyancy aid tank greater than the water yield of secondary valve buoyancy aid tank, therefore main valve buoyancy aid mechanism sinks prior to secondary valve buoyancy aid mechanism, the jointing that is connected with main valve buoyancy aid mechanism on the main valve cursor descends, resilient plug on the main valve cursor rises, and opens the main valve relief hole, and main valve is opened; This moment is because the water yield of secondary valve buoyancy aid tank is few, and secondary valve buoyancy aid mechanism still is in float state, and secondary valve relief hole still is in open mode, current are through out-of-date, secondary valve is opened, and external water source arrives the position of required injection from playpipe, and wherein one current enter water tank by delivery port.
F. after the water outlet of secondary valve buoyancy aid tank acquires a certain degree, water shortage in the secondary valve buoyancy aid tank is to allow secondary valve buoyancy aid mechanism float, pair valve buoyancy aid mechanism sinks, the jointing that is connected with secondary valve buoyancy aid mechanism on the cursor of secondary valve descends, resilient plug on the secondary valve cursor descends, secondary valve relief hole is closed, and secondary valve cuts out.And
G. repeating step b is to step f.
The invention has the beneficial effects as follows:
Simple installation is connected water inlet pipe with external water source, connecting hose on the playpipe, and another termination of described flexible pipe can be used bottom bedpan middle part or bottom or blow-off line entrance.
With low cost, the present invention uses the switching of buoyancy aid mechanism automatic control valve, compares with existing electromagnetic valve etc., and is with low cost.
Automatically control, wash away strong water saving, when cistern water-discharging, playpipe in the water saving fixtures is opened automatically, and water inlet pipe, main valve, secondary valve, playpipe form path, and external water source directly is injected into bedpan middle part or bottom or blow-off line entrance bottom from playpipe through water saving fixtures, the water that promotion is discharged from water tank washes, the present invention can utilize the external water source of different hydraulic pressure, and the water pressure that ejects is large, rinses water saving well.

The below introduces water saving fixtures 66 of the present invention and is installed in water tank 64 course of work when interior:
Consult Figure 28, Figure 20, interior originally anhydrous at water tank 64, water saving fixtures 66 outside each unit status of the present invention as shown in figure 20 at that time, main valve buoyancy aid mechanism 38 and secondary valve buoyancy aid mechanism 36 all are lower shifting state, shown in arrow X arrow Y among Figure 20, consult Figure 25, Figure 26, main valve relief hole 17 was opened at that time, and secondary valve relief hole 18 is closed; Because without external water source or tap water, the spool of main valve and secondary valve inside is lower shifting state because of the elasticity of Elastic valve core diaphragm 57, the anti-siphon spool 51 of anti-siphon valve inside is because deadweight also is lower shifting state, and main valve buoyancy aid tank A bottom also is lower shifting state with the one way valve 62 of secondary valve buoyancy aid tank B bottom because of deadweight;
When having external water source or tap water to intake to the water inlet pipe 12 of water tank 64 outer bottoms, consult 20a, in main valve intake antrum 2, just have current A and flow into, current A makes on the main valve plug and moves, and just has current B to flow in the main valve water chamber 3; Consult Figure 20 b, the passage of current B by being connected between main valve water chamber 3 and the anti-siphon valve intake antrum 4, just there is current C to flow in the anti-siphon valve intake antrum 4, current C makes on the anti-siphon spool 51 and moves, anti-siphon valve water chamber 5 just has current D to flow out, and moves the anti-siphon air channel 19 that is communicated with up and down that has sealed on total valve gap 16 on the anti-siphon spool 51; Consult Figure 20 c, current D just has current E to flow into by the passage that anti-siphon valve water chamber 5 is connected with secondary valve intake antrum 6 in the secondary valve intake antrum 6; Again consult Figure 20 a, current E can arrive delivery port 14 along secondary valve intake antrum 6, just having current F in the delivery port 14 flows out, just having current G in the filling pipe 48 on the water out adapter 47 flows out, just having current H in the outlet pipe 49 flows out, the accessible bedpan of the current G that flows out from filling pipe 48 is used for the bedpan moisturizing, the current H that flows out from outlet pipe 49 flows into water tank, and water tank began to enter into water state (secondary valve can not be opened because secondary valve buoyancy aid mechanism 36 moves down that secondary valve relief hole 18 is closed at that time);
At that time each unit status of the outside of water saving fixtures 66 of the present invention as shown in figure 20, the state of the resilient plug 56 of main valve and secondary valve and the spool of main valve and secondary valve and anti-siphon spool 51 is as shown in Figure 20 a, Figure 20 b, Figure 20 c.
Consult Figure 21, along with continuously outflowing from outlet pipe 49, current H flows in the water tank 64, water tank 64 interior water levels raise gradually, owing in the bottom of main valve buoyancy aid tank A and secondary valve buoyancy aid tank B one way valve 62 is arranged, so rise to along the process of section in the bottom of water tank 66 interior water levels from main valve buoyancy aid tank A and secondary valve buoyancy aid tank B, the one way valve 62 of main valve buoyancy aid tank A and secondary valve buoyancy aid tank B bottom is because be subject to moving and closed check valve hole 40 and unidirectional valve opening 41 in the buoyancy, so main valve buoyancy aid tank A and secondary valve buoyancy aid tank B can not intake, only has the infiltration of minute quantity, be not enough to produce buoyancy and make main valve buoyancy aid mechanism 38 and secondary valve buoyancy aid mechanism 36 come-ups, only have when water level has risen to main water inlet position, the top of main valve buoyancy aid tank A 44, current just can enter in the main valve buoyancy aid tank A from main water inlet position 44, after having water to enter, main valve buoyancy aid mechanism 38 in it just can be owing to the effect that is subject to buoyancy is floated, thereby main valve relief hole 17 is closed, and final plant closure main valve, after main valve is closed, filling pipe 48 on the water out adapter 47 and outlet pipe 49 also go out with regard to anhydrous, and the water inlet of water tank has just stopped; Main valve buoyancy aid mechanism 38 was raised state shown in arrow X among Figure 21 at that time, and secondary valve buoyancy aid mechanism 36 also is lower shifting state shown in arrow Y among Figure 20;
Consult Fig. 8 a, because the main water inlet position 44 on edge is lower than the upper edge of secondary valve buoyancy aid tank B on the main valve buoyancy aid tank A sidewall, so also not having water in the secondary valve buoyancy aid tank B when having water to enter in the main valve buoyancy aid tank A enters, only have after the water in the main valve buoyancy aid tank A advances to expire, just having water flows in the secondary valve buoyancy aid tank B from the pair that interconnects on the share common sidewalls top of main valve buoyancy aid tank A and secondary valve buoyancy aid tank B water inlet position 45, by the time after flowing into water in the secondary valve buoyancy aid tank B and completely arriving to a certain degree, secondary valve buoyancy aid mechanism 36 in the secondary valve buoyancy aid tank B just understands owing to the effect that is subject to buoyancy is floated, thereby secondary valve relief hole 18 is opened, and this moment, main valve was closed, secondary valve has not had water inlet, although secondary valve relief hole 18 is opened and also can be opened, secondary valve just is in a kind of opening for the treatment of, as long as can be opened at once once there being current to flow into secondary valve intake antrum 6; Main valve buoyancy aid mechanism 38 all was raised state with secondary valve buoyancy aid mechanism 36 at that time, shown in arrow X arrow Y among Figure 22;
At that time water saving fixtures of the present invention 66 outside each unit status as shown in figure 22, the resilient plug 56 of main valve and secondary valve and the spool state of main valve and secondary valve are shown in Figure 22 a.
Consult Figure 28, Figure 23, when the drain assembly 65 in opening water tank 64 makes cistern water-discharging, fast-descending along with water tank 64 interior water levels, the one way valve 62 of the outer bottom of main valve buoyancy aid tank A and secondary valve buoyancy aid tank B is not owing to there has been the effect of buoyancy to move down, water in main valve buoyancy aid tank A and the secondary valve buoyancy aid tank B will the unidirectional valve opening 40 of bottom be single separately from them, flow out to valve opening 41, but because the opening degree of the one way valve 62 of main valve buoyancy aid tank A bottom is large, the opening degree less of the one way valve 62 of the bottom of secondary valve buoyancy aid tank B, so the water in the main valve buoyancy aid tank A is will be at once emptying from unidirectional valve opening 40, main valve buoyancy aid mechanism 38 also just moves down at once thereupon, thereby main valve relief hole 17 is unlocked; And the water in the secondary valve buoyancy aid tank B can not flow to end at once, and secondary valve buoyancy aid mechanism 36 also can be the come-up state within a certain period of time, namely can also make secondary valve relief hole 18 be held open state;
Consult 23a, after main valve relief hole 17 was unlocked, the current A in main valve intake antrum 2 will make main valve plug move, and just had current B to flow in the main valve water chamber 3; Consult Figure 23 b, the passage of current B by being connected between main valve water chamber 3 and the anti-siphon valve intake antrum 4, just there is current C to flow in the anti-siphon valve intake antrum 4, current C makes on the anti-siphon spool 51 and moves, anti-siphon valve water chamber 5 just has current D to flow out, and moves the anti-siphon air channel 19 that is communicated with up and down that has sealed on total valve gap 16 on the anti-siphon spool 51; Consult Figure 23 c, the passage that current D is connected with secondary valve intake antrum 6 by anti-siphon valve water chamber 5, just there is current E to flow in the secondary valve intake antrum 6, on the one hand, current E makes on the auxiliary valve core and moves, also namely so that secondary valve is unlocked, just there is current I to flow out in the secondary valve water chamber 7, has current J to eject on the playpipe 13; Main valve buoyancy aid mechanism 38 was lower shifting state shown in arrow X among Figure 23 at that time, and secondary valve buoyancy aid mechanism 36 also is raised state shown in arrow Y among Figure 23;
Again consult Figure 23 a, on the other hand, current E can arrive delivery port 14 along secondary valve intake antrum 6, just having current F in the delivery port 14 flows out, just have current G in the filling pipe 48 on the water out adapter 47 and flow out, just have current H in the outlet pipe 49 and flow out, the accessible bedpan of the current G that flows out from filling pipe 48 is used for the bedpan moisturizing, the current H that flows out from outlet pipe 49 flows into water tank, and water tank enters simultaneously into the water state;
At that time water saving fixtures of the present invention 66 outside each unit status as shown in figure 23, the resilient plug 56 of main valve and secondary valve and the spool of main valve and secondary valve reach prevent siphon spool 51 state as shown in Figure 23 a, Figure 23 b, Figure 23 c.
Again consult Figure 20, wait be a period of time after, after 3 to 8 seconds, the water yield in the secondary valve buoyancy aid tank B is flow to end gradually, and the secondary valve buoyancy aid mechanism 36 of section will make secondary valve relief hole 18 be closed owing to the effect that has lost buoyancy moves down so within it, auxiliary valve core moves down, and namely secondary valve is closed;
Each unit status of the outside of water saving fixtures 66 of the present invention as shown in figure 20 at that time, main valve buoyancy aid mechanism 38 and secondary valve buoyancy aid mechanism 36 all are lower shifting state, shown in arrow X arrow Y among Figure 20, the state of the resilient plug 56 of main valve and secondary valve and the spool of main valve and secondary valve and anti-siphon spool 51 is as shown in Figure 20 a, Figure 20 b, Figure 20 c.
So far, all parts of water saving fixtures 66 of the present invention have all entered the water inlet state of initial water tank 64, have begun to enter the circulation of next round.
The specific embodiment two
In the specific embodiment one, be provided with an anti-siphon valve, whether the existence of anti-siphon valve has not a particle of impact to the switching of major-minor valve in fact, mainly be to produce negative pressure for water supply pipe when the tap water cut-off, anti-siphon spool 51 moves down and covers anti-siphon valve intake antrum 4, enter in the valve the anti-siphon air channel 19 that air can be communicated with up and down from total valve gap 16 again, the negative pressure of water supply pipe generation can not play a role playpipe 13 and outlet pipe 49 and filling pipe 48 like this, has guaranteed that like this water in water tank and the bedpan can be by suck-back; If do not consider above-mentioned factor, can not prevent siphon valve, on the basis of the specific embodiment one, as long as removing the anti-siphon air channel 19 that is communicated with up and down on anti-siphon spool 51 and the total valve gap 16 blocks, anti-siphon valve like this has been equal to nothing, anti-siphon valve intake antrum 4 has originally all become the communicating passage of main valve water chamber 3 with secondary valve intake antrum 6 with anti-siphon valve water chamber 5, just only have main valve to reach adjacent with it secondary valve in this sample specific embodiment two, in this specific embodiment two except above-mentioned removed anti-siphon spool 51 and the anti-siphon air channel 19 that is communicated with up and down on total valve gap 16 blocked, remaining all parts all with the specific embodiment one in striking resemblances, operating principle and step are also the same, here no longer repeat tiltedly to state.
Remark additionally:
Main water inlet position 44 on the main valve buoyancy aid tank A sidewall is designed to be lower than the purpose on the upper edge of secondary valve buoyancy aid tank B, for first water inlet in the main valve buoyancy aid tank A when water tank 64 interior water levels rise, a slow stepping water in the secondary valve buoyancy aid tank B, if the words of intaking simultaneously, pair valve buoyancy aid mechanism 36 also can be as moving on the horse back the main valve buoyancy aid mechanism 38, open auxiliary valve relief hole 18, although and main valve buoyancy aid mechanism 38 also moves on the horse back synchronously at this moment, closed main valve relief hole 17, but can at once not close main valve, because the moving process of main valve plug needs the of short duration time, thereby so secondary valve will of short duration unlatching cause playpipe 13 that of short duration water spray is arranged.
The first watertight shutter 33 is set below main valve cursor 29 and at total valve gap 16 the second watertight shutter 23 is set, the 3rd watertight shutter 24 and flowing water breach 26, the purpose of flowing water breach 28, in order to work as main valve relief hole 17, although from their outflows when secondary valve relief hole 18 is opened is that very little water flow energy is by the first watertight shutter 33, the second watertight shutter 23, the 3rd watertight shutter 24 blocks rear from flowing water breach 26, flowing water breach 28 flows out, and is unlikely to flow into the normal come-up that affects main valve buoyancy aid mechanism 38 and secondary valve buoyancy aid mechanism 36 in following main valve buoyancy aid tank A and the secondary valve buoyancy aid tank B.
The purpose of the 4th watertight shutter 25 and flowing water breach 27 is set at total valve gap 16, be for the faint water flow energy that flows out from anti-siphon air channel 19 when current are arranged by anti-siphon valve flows out from flowing water breach 27 after being blocked by the 4th watertight shutter 25, and be unlikely to flow into the normal come-up that affects main valve buoyancy aid mechanism 38 and secondary valve buoyancy aid mechanism 36 in following main valve buoyancy aid tank A and the secondary valve buoyancy aid tank B.
The purpose of dredging needle 54 all is set in the spool aperture 61 of main valve and secondary valve, for when spool moves up and down, dredging needle 54 and spool aperture 61 are relatively moved, play the effect of dredging spool aperture 61, spool aperture 61 is stopped up by dirt not too easily.
The water flowing area of water inlet pipe, main valve intake antrum, main valve water chamber, secondary valve intake antrum, secondary valve water chamber, playpipe is designed to purpose between the 30mm2 to 250mm2, in order to reduce the water flowing passage to the resistance of current, to make water saving fixtures of the present invention can be suitable for lower hydraulic pressure.
The valve class professional of the industry can change concrete internal construction of the present invention by the internal part that changes valve, as water inlet middle part water outlet around the major-minor valve among the present invention being changed into such as water outlet around the middle part water inlet of common water intaking valve, namely intake antrum and water chamber conversely; Also can change concrete external structure of the present invention by the external component that changes valve, as major-minor valve cursor and buoyancy aid mechanism and one way valve are out of shape, above-mentioned change all belongs to protection scope of the present invention.
