In this embodiment, the waterseal component 60 comrises a needle valve sleeve 610 and a rubber fitting 620 abutting against the needle valve sleeve 610. he protruding block 630 abuts against the needle valve sleeve 610. The needle valve 900 is movably assembled inside the valve body 100, one end of the needle valve 900 is fixed to the waterseal component 600, another end of he needle valve 900 inserts into the through hole 710 to control the flow volume of the backpressure cavity 800 with the through hole 710. In this embodiment, the needle valve 900 comprises a needle valve body, the external periphery of the center of the needle valve body is concaved with an annular hollow 910, the clearance of end portion of the needle valve body and the through hole '710 is smaller than the clearance of the annular hollow 910 of the needle valve body and the through hole 710, The water deflector plate 500 composes a main body 500, which is disposed with a front side and a rear side. she an body 501) is disposed with an assembly hole 520 throughout front and rear and am 'duan of water diversion holes 530 armularly distributed on the outside of the assembly hole 520 thWiughout front and rear. The external periphery of the main body 500 is concaved with an inlet groove 510, the rea side ot' the main body 500 is concaved with an assembly cavity 540 conneced to the inlet groove 510, said assembly hole and the water diversion holes 530 are disposed at the bottom side of the assembly cavity 540. The rear side of the main body 500 is contacted to the valve d e assembly hole 520 is corresponding to the outlet of the outlet passage 140. the front side of the main body 500 is corresponding to the front side of the waterseal component 60A the protruding block 630 runs through the assembly hole 520 to slidably closely contacted o the outlet passage, the inlet groove 510 is connected to the inlet passage 110, Preferred, the assembly Pole 520 is disposed at the center of the main body 500, the axis thereof coincides with the axis of the main body 500. In this embodiment, the main body 500 is further disposed wih a throughout hole 550 throughout the main body 500 front and rear. The periphery side o' the assembly hole 520 is disposed with an annular wall 560 at the rear side of the main body 500, the anmular wall 560 separates the assembly hole 520 and the water diverson holes 530. Prckerred. te annlar wal 560 s sleeved on the external periphery of the outlet of the outlet passage 140. The dcompressing unit is assembled inside the valve bi comprises a decompressing passage Bt and a gland 150, one end of the decompressing passage 130 is connected to the via hole 720, the land 150 covers the other end of the decompressing passage 130, and the gland 150 drivingly connected to a float 200. In this embodiment, the throughout hole 550 is connected to the via hole 70 and the decompressing passage 130. When water of the water tank evels down, the float 200 fails down to drive the gland 150 connected to the foat 200 to open, so that the decompressing passage 130 is open, water of the backpressure cavity 800 flows out of the decompressing passage, water pressure decreases, when the water pressure is smaller than that from the inlet passage 110 to the water diversion holes 530 through the inIet groove 510, the waterseal component 600 and the needle valve 900 moves toward the ale cover 70(10 under the work of water pressure difference, meanwhile, with the water deflector plate, water of the inlet groove 510 flows to the water diversion holes 530 through the assembly cavity 540 and compacts the waterseal component 600, so that the protruding block 630 cf the waterseal component 600 leaves away from the assembly hole 520, water flows to the front side ot the water deflector plate from the water diversion holes 530, and then flows from the front side of the water deflector plate 500 to the outlet passage 140 through the assembly hole 520 thus to supply to the water tank. At this time, the needle valve 900 is driven by the waterseal component 600, the end portion of the needle valve body works with the through hole 710 Flrstly, then the annular hollow 910 of the needle valve body works with the through hole 710, as the clearance ot end portion of the needle valve body and the through hole 710 is smaller than the clearance of the annular hollow 910 of the needle valve body and the through hole 710, flow voltume gradual enlarges from the through hole 710 to the backpressure cavity When water afull in the water tatk, the foat 200 floats up and drives the gland. 150 to make the gland 150 ciosc the decompressing passage 130. At this time, water pressure of the backpressure cavity 800 is equal to the water pressure of the inlet passage 110, but the stressed area of the waterseal component 600 at the backpressure cavity 800 is larger than that at the water deflector plate 600, so that the waterseal component 600 moves toward the outlet passage 140 to close the oudet passage t stop water Alhough the prem: invention has been described with reference to the preferred embodiments thereof for carrying out the patent for intention it iS apparent to those skilled in the art that a variety oi modliteations and changes may be made without departing from the scope of the patent rOem WaclO 9 Ui haWndest be defined by the appended cdaims uInustrial atppicability the. ~~e~ ; , Y ;tWztr iank Wf the present ineiknhs h apabiliy toeven the stressed force dftewatre tmon. thus ?emgthen the lie saoftewesalcmponent.
