Mainly consult Fig. 7 to shown in Figure 12, working principle of the present invention is as follows:
1, for the first time pressure release: when the flushing valve closed condition, such as Fig. 7, shown in Figure 9, circuit applies negative impulse to electromagnetic valve component 2, iron core 22 discharges, withstand first pressure release passage 25 in solenoid valve seat chamber 24, make solenoid valve seat chamber 24 and the 25 not conductings of the first pressure release passage, all runners of flushing valve all are in a kind of pressure balance, thereby make flushing valve close not water outlet; When just opening flushing valve, as shown in Figure 8, circuit applies positive pulse to electromagnetic valve component 2, iron core 22 adhesives retreat, solenoid valve seat chamber 24 and 25 conductings of the first pressure release passage, make the water in the solenoid valve seat chamber 24 flow to pressure-releasing chamber 13 by the first pressure release passage 25, thereby flow away from water outlet 12, finish for the first time pressure release.
2, for the second time pressure release: more as shown in Figure 8, because solenoid valve seat chamber 24 is communicated with upper diaphragm die cavity 331, when the water that can drive upper diaphragm die cavity 331 that flows away of the water in the solenoid valve seat chamber 24 flows away in also by solenoid valve seat chamber 24 and the first pressure release passage 25, thereby the pressure of upper diaphragm die cavity 331 is diminished, the lifting that makes progress of heavy caliber diaphragm compression shock lower moment of die cavity 333 in lower diaphragm, thereby the interior die cavity 333 of diaphragm and the outer die cavity 332 of lower diaphragm under the conducting, make water die cavity 333 in lower diaphragm of the outer die cavity 332 of lower diaphragm flow to pressure-releasing chamber 13, also flow away from water outlet 12, finish for the second time pressure release.
3, for the third time pressure release: as shown in figure 10, because the outer die cavity 332 of lower diaphragm is communicated with piston valve epicoele 151, when the water of die cavity 332 flows away outside lower diaphragm, water on the plug valve epicoele 151 can be supplemented to the outer die cavity 332 of lower diaphragm, thereby die cavity 333 flow to pressure-releasing chamber 13 in the lower diaphragm, finally flow away from water outlet 12, because heavy caliber diaphragm 31 bores are large, sluicing runner unit area is large, the instant water of plug valve epicoele 151 is forced to drain by water pressure, also die cavity 332 outside lower diaphragm successively, die cavity 333 in the lower diaphragm, pressure-releasing chamber 13 flows away from water outlet 12 at last, finishes for the third time pressure release.
4, bath: more as shown in figure 10, can make piston assembly 4 whole come-ups in the time of the draining of the water of plug valve epicoele 151, caulking gum pad 46 loses sealing, thereby the described piston valve cavity of resorption 152 of conducting and bath chamber 14, because described inlet channel 11 directly is communicated with described piston valve cavity of resorption 152 by described filter screen 44, so inlet channel 11 and water outlet also transient switching, water instantaneous (different depending on the pressure different flow) is gone out solenoid valve and is finished bath.
5, manually pressure release: when electromagnetic valve component 2 dead electricity or damage ring, need with manual pressure release bath, as shown in figure 11, be manual assembly 5 closed conditions, at this moment, under the effect of Returnning spring 54, hand is in upper top state by connecting rod 53, hand is pressed seal ring 56 and hand on the connecting rod 53 and press cavity 52 and form and seal, make hand by epicoele 521 and hand by cavity of resorption 522 not conductings; When pressing connecting rod 53 by the assistant, seal ring 56 moves down by connecting rod 53 conveniently and loses sealing, hand is on state by epicoele 521 and hand by cavity of resorption 522, thereby make the water of piston valve epicoele 151 flow to hand by cavity 52 outer walls by cavity of resorption 522, hand by epicoele 521, water port 57 via manual pressure-releasing chamber 55, hand successively, arrive pressure-releasing chamber 13, finish pressure release, can realize bath after the pressure release.
Although more than described the specific embodiment of the present invention; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present invention; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present invention, all should be encompassed in the scope that claim of the present invention protects.
