Said needle-valve 900, it is installed in the said valve body 100 movably, and an end of said needle-valve 900 is fixed in the sealing assembly 600, and the other end stretches into said through hole 710 and cooperates control to get into the size of back pressure cavity 800 current with said through hole 710.In the present embodiment, said needle-valve 900 comprises a needle-valve body, the said needle-valve body middle part outer circumferential face ring-shaped depression 910 that sets to the concave, the gap that the gap that the needle-valve body end cooperates with said through hole 710 cooperates with said through hole 710 less than needle-valve body ring-shaped depression 910.
Said water guide board 500, it comprises a main body 500, said main body 500 has positive and a back side dorsad, said main body 500 be provided with one just carrying on the back the pilot hole 520 that runs through and a plurality of annular display encirclement pilot holes 520 just carry on the back the pod apertures 530 that runs through.Said main body 500 outer circumferential faces are arranged with one and are just carrying on the back the intake chamber 510 that runs through, and said main body 500 back sides are arranged with the assembly cavity 540 of a connection intake chamber 510, and said assembly cavity 540 bottom surfaces are provided with described pilot hole 520 and pod apertures 530.Said main body 500 back sides abut against valve body 100; The water outlet of said pilot hole 520 corresponding exhalant canals 140; The front of said main body 500 positive corresponding said sealing assemblies 600; And said projection 630 passes pilot hole 520 and can seal slidably and abut against exhalant canal, and said intake chamber 510 is connected intake tunnels 110.Best, said pilot hole 520 is positioned at main body 500 centers, and its axis is consistent with main body 500 axis.In the present embodiment, said main body 500 also be provided with one run through the main body 500 positive back sides penetration hole 550.Said pilot hole 520 side faces are convexly equipped with an annular wall 560 along said main body 500 back sides, and said annular wall 560 is separated from each other pilot hole 520 and pod apertures 530.Best, said annular wall 560 is socketed in the outer circumferential face of the water outlet of exhalant canal 140.
Said pressure release unit; It is installed in the valve body 100, and it comprises a pressure release passage 130 and a gland 150, and a termination of said pressure release passage 130 is led to said via hole 720; Said gland 150 lids are connected on the other end of pressure release passage 130, and said gland 150 keg float 200 that is in transmission connection.In the present embodiment, said penetration hole 550 is connected said via hole 720 and said pressure release passage 130.
When the water tank middle water level descends, drive keg float 200 and descend, the gland 150 of the keg float 200 that is in transmission connection is opened under the effect of keg float 200; Thereby pressure release passage 130 is opened, and the water in the back pressure cavity 800 flows out from pressure release passage at this moment, and hydraulic pressure diminishes; Less than when intake tunnel 110 flows into the hydraulic pressure of pod apertures 530 through intake chamber 510, sealing assembly 600 moves towards valve gap 700 directions under the effect of differential water pressures with needle-valve 900, at this moment up to its hydraulic pressure; Effect through water guide board 600; Flow to pod apertures 530 from the current of intake chamber 510 through assembly cavity 540, and impact sealing assembly 600, make the projection 630 of sealing assembly 600 leave pilot hole 520; Current flow to water guide board 500 fronts from pod apertures 530, and are positive through 140 pairs of water tank moisturizings of pilot hole 520 inflow exhalant canals from water guide board 500 again.At this moment; Needle-valve 900 is under the drive of sealing assembly 600; The needle-valve body end cooperates with said through hole 710 earlier, and afterwards, the ring-shaped depression 910 of needle-valve body cooperates with said through hole 710; Because the gap that the gap that the needle-valve body end cooperates with said through hole 710 cooperates with said through hole 710 less than needle-valve body ring-shaped depression 910 makes from the current gradual change of through hole 710 entering back pressure cavity big.
When tank water was full, keg float 200 come-ups, and the gland 150 that is in transmission connection were with gland 150 sealing pressure release passages 130.At this moment, the hydraulic pressure of back pressure cavity 800 equates with the hydraulic pressure at intake tunnel 110 places, still; Sealing assembly 600 is at the lifting surface area of back pressure cavity 600 lifting surface area greater than water guide board 600 places; Make sealing assembly 600 move, with exhalant canal 140 sealings, no longer water inlet to exhalant canal 140 directions.
The above is merely preferred embodiment of the present invention, so can not limit the scope that the present invention implements according to this, the equivalence of promptly doing according to claim of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
