H, repeating step d are to step g.
The switching principle of the switching principle of the switching principle of water intaking valve of the present invention and injection 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through open and close valve and the pressure differential of cavity of resorption reach open and close valve; Through out-of-date, the relief hole shut off valve on the valve gap just is closed as current, and the relief hole opening valve on the valve gap just is unlocked, and is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.
Workflow of the present invention is following:
A. injection water saving fixtures of the present invention are 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.Anhydrous in the water tank at this moment, water intaking valve buoyancy aid mechanism and injection valve buoyancy aid mechanism do not float.
When water intaking valve buoyancy aid mechanism does not float; The jointing that is connected with water intaking valve buoyancy aid mechanism on the water intaking valve cursor is the decline state; Because the resilient plug of the water intaking valve valve gap relief hole of water intaking valve cursor top and jointing are in the both sides of rotating fulcrum; Therefore the resilient plug on the water intaking valve cursor is a propradation, and the water intaking valve relief hole is an open mode; Injection valve controlling organization and water intaking valve controlling organization are the parallel controlling organizations of two covers, and principle is the same, so when injection valve buoyancy aid mechanism did not float, the injection valve relief hole also was an open mode.
B. open external water source, current are from the intake antrum of water inlet pipe entering water intaking valve and injection valve, because the relief hole of water intaking valve and injection valve is an open mode; When current pass through; Water intaking valve and injection valve are opened, and water intake valve chamber and water chamber are connected, and injection valve intake antrum and water chamber are connected; The passage, the delivery port that are connected mutually through water inlet pipe, water intake valve chamber, water intaking valve water chamber, water intaking valve water chamber and delivery port successively of one current wherein; Passage, playpipe that another strand current are connected mutually through water inlet pipe, injection valve intake antrum, injection valve water chamber, injection valve water chamber and playpipe successively; Because delivery port is guided injection valve buoyancy aid jar into, behind the current inflow injection valve buoyancy aid jar of delivery port outflow, injection valve buoyancy aid mechanism is floated, the injection valve relief hole is closed, thereby injection valve cuts out.
C. the current that flow out from delivery port flow into water tank after flowing into injection valve buoyancy aid jar again, and after continuing to flow into a period of time, the water tank middle water level rises; The water inlet of water intaking valve buoyancy aid jar, water intaking valve buoyancy aid mechanism floats, and the jointing that is connected with water intaking valve buoyancy aid mechanism on the water intaking valve cursor rises; The resilient plug of the water intaking valve valve gap top on the water intaking valve cursor descends, and the water intaking valve relief hole is closed, and water intaking valve is closed; The intake antrum and the water chamber of water intaking valve are not communicated with, and stop to the water supply of water tank.
D. water tank opening water discharge; Drawdown in the water tank, the water when making water outlet owing to the one way valve opening degree of water intaking valve buoyancy aid jar bottom is less in the water intaking valve buoyancy aid jar can not flow to end at once, so water intaking valve buoyancy aid mechanism can not move down at once; The water intaking valve relief hole is still closed, and water intaking valve is still closed; And the water of injection valve buoyancy aid jar all flows to end from the drainage hole of its underpart at once; Injection valve buoyancy aid mechanism sinks, and the jointing that is connected with injection valve buoyancy aid mechanism on the injection valve cursor descends, and the resilient plug on the injection valve cursor rises; Open the injection valve relief hole, injection valve is opened.
E. after the water outlet of water intaking valve buoyancy aid jar acquires a certain degree; Water shortage in the water intaking valve buoyancy aid jar is to let water intaking valve buoyancy aid mechanism float; Water intaking valve buoyancy aid mechanism sinks, and the jointing that is connected with water intaking valve buoyancy aid mechanism on the cursor of water intaking valve descends, and the resilient plug on the water intaking valve cursor rises; The water intaking valve relief hole is opened, and water intaking valve is opened.And
F. repeating step b is to step e.
The invention has the beneficial effects as follows:
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 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 is washed away strong water saving, when cistern water-discharging; The playpipe that sprays in the water saving fixtures is opened automatically, and water inlet pipe, water intaking valve, injection 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 spraying water saving fixtures; The water that promotion is discharged from water tank washes; The external water source of the present invention's different hydraulic pressure capable of using, the water pressure that ejects is big, rinses water saving well.
