J, current through flowing to water valve intake antrum, water intaking valve water chamber, water intaking valve water chamber and passage, outlet pipe that outlet pipe is connected mutually, enter into water tank from water inlet pipe; And
K, repeating step b are to step j.
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 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and the pressure differential of cavity of resorption reach open and close valve; When current being arranged through out-of-date, the relief hole shut off valve on the valve gap just is closed, and the relief hole opening valve on the valve gap just is unlocked, and is specific as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, go out valve body by the water of the arrival of the aperture on spool valve body epicoele is very fast 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.
