The switching principle of the switching principle of the switching principle of main valve of the utility model 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 through open and close valve and the pressure differential of cavity of resorption reach open and close valve; Through out-of-date, the relief hole shut off valve on the valve gap just is closed as current, and the relief hole opening valve on the valve gap just is unlocked, and is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, and spool is divided into epicoele and cavity of resorption with valve inner; Cavity of resorption comprises intake antrum and water chamber, and the valve body epicoele communicates with cavity of resorption through the aperture on the spool, when relief hole is in closed condition and has current to get into; Part water reaches the valve body epicoele through the aperture on the spool, and this moment, spool received the downward applied pressure of water and the water in the intake antrum in the epicoele applied pressure that makes progress, and 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, because 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 receives of spool is greater than upwarding pressure, and spool is in shifting state down, cuts off the connection of intake antrum and water chamber.This state is called the closed condition of this valve body.
When relief hole was in opening, the valve body epicoele communicated with the external world through relief hole, because the hole diameter on the spool is less than the diameter of relief hole on the valve gap; When current got into, the water that reaches the valve body epicoele through the aperture on the spool went out valve body through letting out little pressure orifice flow very soon, and the downward pressure that spool receives upwards pressure less than what it received; 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.
Can find out that to sum up when current passed through, relief hole was closed and then caused valve to be closed, relief hole is opened and is then caused opening of valves.Therefore, control the switching of relief hole, just controlled the switching of valve, thus the outflow of controlled water flow.
The workflow of the utility model is following:
A. the water-saving valve with the utility model is fixedly mounted in the water tank; The lower end that makes water inlet pipe and playpipe is outside water tank; Be connected water inlet pipe with external water source, connect flexible pipe on the playpipe, another termination of said flexible pipe is to bedpan middle part or bottom or blow-off line inlet bottom.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 a propradation, and the main valve relief hole is an 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 a closed condition.
B. open external water source, current are from the intake antrum of water inlet pipe entering main valve, because the main valve relief hole is an open mode, when current passed through, main valve was opened, and main valve intake antrum and water chamber are connected; Current are successively through main valve intake antrum, main valve water chamber, the secondary valve intake antrum of entering; Or current are successively through main valve intake antrum, main valve water chamber, anti-siphon valve intake antrum, anti-siphon valve water chamber, the secondary valve intake antrum of entering; Because secondary valve relief hole is closed condition, valve core of auxiliary valve is in shifting state down, and secondary valve intake antrum and water chamber are not communicated with, the delivery port entering water tank on the passage that the intake antrum of water chamber and the secondary valve of current through being positioned at main valve is connected.
C. after external water source continued to flow into a period of time, the water tank middle water level rose, because the different main valve buoyancy aid mechanisms that can make with the water inlet structure of secondary valve buoyancy aid jar of main valve buoyancy aid jar 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; The 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; Drive on the secondary valve cursor jointing that is connected with secondary valve buoyancy aid mechanism and rise, 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; Drawdown in the water tank, because the different water yields that make main valve buoyancy aid jar during water outlet with the one way valve opening degree of secondary valve buoyancy aid jar bottom of the one way valve of main valve buoyancy aid jar bottom are greater than the water yield of secondary valve buoyancy aid jar, so main valve buoyancy aid mechanism is prior to the sinking of 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 jar 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 get into water tank through delivery port.
After the water outlet of f. secondary valve buoyancy aid jar acquires a certain degree; Water shortage in the secondary valve buoyancy aid jar is to let secondary valve buoyancy aid mechanism float; Secondary valve buoyancy aid mechanism sinks, and the jointing that is connected with secondary valve buoyancy aid mechanism on the cursor of secondary valve descends, and the 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 beneficial effect of the utility model is:
Simple installation is connected water inlet pipe with external water source, connect flexible pipe on the playpipe, and another termination of said flexible pipe can be used bottom bedpan middle part or bottom or blow-off line inlet.
With low cost, the utility model uses the switching of buoyancy aid mechanism automatic control valve, compares with existing electromagnetic valve etc., and is with low cost.
Automatically control is washed away strong water saving, when cistern water-discharging; Playpipe in the water-saving valve 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 inlet bottom from playpipe through water-saving valve; The water that promotion is discharged from water tank washes; The external water source of the utility model different hydraulic pressure capable of using, the water pressure that ejects is big, rinses water saving well.

In sum, when main valve buoyancy aid mechanism 38 come-ups, main valve relief hole 17 will be closed, and when main valve buoyancy aid mechanism 38 moved down, main valve relief hole 17 will be unlocked; When secondary valve buoyancy aid mechanism 36 come-ups, secondary valve relief hole 18 will be unlocked, and when secondary valve buoyancy aid mechanism 36 moved down, secondary valve relief hole 18 will be closed.
The switching principle of comprehensive aforesaid major-minor valve can obtain to draw a conclusion: the water-saving valve at the utility model connects under the situation at external water source, and when main valve buoyancy aid mechanism 38 come-ups, main valve is closed, and when main valve buoyancy aid mechanism 38 moved down, main valve was unlocked; When secondary valve buoyancy aid mechanism 36 come-ups, but secondary valve be unlocked or be in opening, when secondary valve buoyancy aid mechanism 36 moved down, secondary valve was closed.
The course of work when water-saving valve 66 of introducing the utility model below is installed in the water tank 64:
Consult Figure 28, Figure 20; Originally anhydrous in water tank 64, outside each unit status of the water-saving valve 66 of the utility model were shown in figure 20 at that time, and main valve buoyancy aid mechanism 38 and secondary valve buoyancy aid mechanism 36 all are shifting state down; 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 do not have external water source or tap water; The spool that main valve and secondary valve are inner is shifting state down because of the elasticity of Elastic valve core diaphragm 57; The anti-siphon spool 51 that anti-siphon valve is inner is because deadweight also is shifting state down, and main valve buoyancy aid jar A bottom also is shifting state down with the one way valve 62 of secondary valve buoyancy aid jar B bottom because of deadweight;
During to water inlet pipe 12 water inlets of water tank 64 outer bottoms, consult 20a as external water source or tap water, 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 through 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, and anti-siphon valve water chamber 5 just has current D to flow out, and moves the anti-siphon air channel of having sealed on total valve gap 16 19 that is communicated with up and down on the anti-siphon spool 51; Consult Figure 20 c, current D just has current E to flow into through 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 has current F in the delivery port 14 and flows out, and just has current G in the filling pipe 48 on the water out adapter 47 and flows out; Just having current H in the outlet pipe 49 flows out; The current G that from filling pipe 48, flows out can insert bedpan and be used for the bedpan moisturizing, and the current H that from outlet pipe 49, flows out flows into water tank, and water tank begins to get into water inlet 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);
Each unit status of outside of the water-saving valve 66 of the utility model was shown in figure 20 at that time, shown in 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 such as Figure 20 a, Figure 20 b, Figure 20 c.
Consult Figure 21, flow in the water tank 64 along with current H pours from outlet pipe 49, water level raises gradually in the water tank 64; Owing in the bottom of main valve buoyancy aid jar A and secondary valve buoyancy aid jar B one way valve 62 is arranged all, so water level rises to the process of upper edge portion from the bottom of main valve buoyancy aid jar A and secondary valve buoyancy aid jar B water tank 66 in, the one way valve 62 bottom main valve buoyancy aid jar A and the secondary valve buoyancy aid jar B moves in the buoyancy and seals unidirectional valve opening 40 and unidirectional valve opening 41 because of receiving; So main valve buoyancy aid jar A and secondary valve buoyancy aid jar B can not intake; Have only 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, have only when water level has risen to the main water inlet in top 44 of main valve buoyancy aid jar A; Current just can get in the main valve buoyancy aid jar A from main water inlet position 44; After water got into, the main valve buoyancy aid mechanism 38 in it just can float owing to receiving buoyancy function, thereby main valve relief hole 17 is closed; And final plant closure main valve; After main valve was closed, filling pipe on the water out adapter 47 48 and outlet pipe 49 also went 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 down shifting state shown in arrow Y among Figure 20;
Water-saving valve 66 outside each unit status of the utility model were shown in figure 21 at that time; Shown in the resilient plug 56 of main valve and secondary valve and the spool state of main valve and secondary valve such as Figure 21 a, the inner anti-siphon spool 51 of the anti-siphon valve of impact that has not had current is because deadweight moves down again.
Consult Fig. 8 a; Because the main water inlet position 44 of main valve buoyancy aid jar A sidewall upper edge is lower than the upper edge of secondary valve buoyancy aid jar B; Get into so when having water to get in the main valve buoyancy aid jar A, also do not have water in the secondary valve buoyancy aid jar B, have only when the water in the main valve buoyancy aid jar A advance full after, just have water and intake from the pair that interconnects on the share common sidewalls top of main valve buoyancy aid jar A and secondary valve buoyancy aid jar B and 45 flow in the secondary valve buoyancy aid jar B; By the time after flowing into water in the secondary valve buoyancy aid jar B and completely arriving to a certain degree; Secondary valve buoyancy aid mechanism 36 in the secondary valve buoyancy aid jar B just can float owing to receiving buoyancy function, thereby makes secondary valve relief hole 18 unlatchings, and main valve has been closed at this moment; Secondary valve has not had water inlet; Though secondary valve relief hole 18 is opened and also can be opened, secondary valve just is in a kind of opening of treating, 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;

Consult Figure 28, Figure 23; When the drain assembly 65 in opening water tank 64 makes cistern water-discharging; Quick decline along with water level in the water tank 64; The one way valve 62 of the outer bottom of main valve buoyancy aid jar A and secondary valve buoyancy aid jar B has not been owing to there has been buoyancy function to move down, the water in main valve buoyancy aid jar A and the secondary valve buoyancy aid jar B will from they separately the unidirectional valve opening of bottom 40 single, flow out to valve opening 41, but because the opening degree of the one way valve 62 of main valve buoyancy aid jar A bottom is big; The opening degree of the one way valve 62 of the bottom of secondary valve buoyancy aid jar B is less relatively; So the water in the main valve buoyancy aid jar A will be at once from unidirectional valve opening 40 emptyings, 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 jar 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, just 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 on the main valve plug and move, and just had current B to flow in the main valve water chamber 3; Consult Figure 23 b; The passage of current B through 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, and anti-siphon valve water chamber 5 just has current D to flow out, and moves the anti-siphon air channel of having sealed on total valve gap 16 19 that is communicated with up and down on the anti-siphon spool 51; Consult Figure 23 c; Current D just has current E to flow into, on the one hand through the passage that anti-siphon valve water chamber 5 is connected with secondary valve intake antrum 6 in the secondary valve intake antrum 6; Current E makes on the auxiliary valve core and moves; Make promptly that also secondary valve is unlocked, just have current I to flow out in the secondary valve water chamber 7, have current J to eject on the playpipe 13; Main valve buoyancy aid mechanism 38 was down 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 current G that from filling pipe 48, flows out can insert bedpan and be used for the bedpan moisturizing; The current H that from outlet pipe 49, flows out flows into water tank, and water tank gets into the water inlet state simultaneously;
Water-saving valve 66 outside each unit status of the utility model were shown in figure 23 at that time, shown in 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 such as 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 jar B is flow to end gradually, and the secondary valve buoyancy aid mechanism 36 of portion moves down owing to having lost buoyancy function within it, and secondary valve relief hole 18 is closed; Auxiliary valve core moves down, and promptly secondary valve is closed;
Each unit status of outside of the water-saving valve 66 of the utility model was shown in figure 20 at that time; Main valve buoyancy aid mechanism 38 and secondary valve buoyancy aid mechanism 36 all are shifting state down; Shown in arrow X arrow Y among Figure 20, shown in 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 such as Figure 20 a, Figure 20 b, Figure 20 c.
So far, all parts of the water-saving valve 66 of the utility model have all got into the water inlet state of initial water tank 64, have begun to get into the circulation of next round.
Remark additionally:
Being designed to be lower than the purpose of the upper edge of secondary valve buoyancy aid jar B to the main water inlet position 44 on the main valve buoyancy aid jar A sidewall, is to intake a slow stepping water in the secondary valve buoyancy aid jar B for elder generation in the main valve buoyancy aid jar A when water level water tank 64 in rises; If the words of intaking simultaneously; Secondary valve buoyancy aid mechanism 36 also can move at once as main valve buoyancy aid mechanism 38, open auxiliary valve relief hole 18, though and this moment main valve buoyancy aid mechanism 38 also move on the horse back synchronously; Closed main valve relief hole 17; But can not close main valve at once, 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.
First watertight shutter 33 is being set below the main valve cursor 29 and the purpose of second watertight shutter 23, the 3rd watertight shutter 24 and flowing water breach 26, flowing water breach 28 is being set on total valve gap 16; Though be to be that very little current can be blocked the back and flow out from flowing water breach 26, flowing water breach 28 by first watertight shutter 33, second watertight shutter 23, the 3rd watertight shutter 24, and be unlikely to flow into the interior normal come-up that influences main valve buoyancy aid mechanism 38 and secondary valve buoyancy aid mechanism 36 of following main valve buoyancy aid jar A and secondary valve buoyancy aid jar B for what when main valve relief hole 17, secondary valve relief hole 18 opened, flow out from their.
The purpose of the 4th watertight shutter 25 and flowing water breach 27 is set on total valve gap 16; Be to flow out from flowing water breach 27, and be unlikely to flow into the normal come-up that influences main valve buoyancy aid mechanism 38 and secondary valve buoyancy aid mechanism 36 in following main valve buoyancy aid jar A and the secondary valve buoyancy aid jar B for the faint current that flow out from anti-siphon air channel 19 during through anti-siphon valve as current can be blocked the back by the 4th watertight shutter 25.
The purpose of mediation pin 54 all is set in the spool aperture 61 of main valve and secondary valve; Be for when spool moves up and down; Mediation pin 54 is relatively moved with spool aperture 61, play the effect of mediation spool aperture 61, spool aperture 61 is stopped up by dirt not too easily.
Is the water flowing area design of water inlet pipe, main valve intake antrum, main valve water chamber, secondary valve intake antrum, secondary valve water chamber, playpipe the purpose between the 30mm2 to 250mm2; Be in order to reduce the resistance of water flowing passage, to make the water-saving valve of the utility model can be suitable for lower hydraulic pressure to current.
The valve class professional of the industry can change the concrete internal construction of the utility model through the internal part that changes valve; As changing water inlet middle part water outlet around the major-minor valve in the utility model into, promptly conversely intake antrum and water chamber like water outlet around the middle part water inlet of common water intaking valve; Also can change the concrete external structure of the utility model through the external component that changes valve, as being out of shape major-minor valve cursor and buoyancy aid mechanism and one way valve, above-mentioned change all belongs to the protection domain of the utility model.
