Owing to take technique scheme, the utlity model has following advantage and effect:

1, the utility model is used for the flushing of Device for relieving nature, as long as depress foot panel, the flushing valve meeting did not need people's the manipulation flushing that discharges water automatically when the people left away, and the length of washing time can be adjusted.

2, the utility model is simple in structure, and reliable operation is cheap, and maintenance and repair are simple and easy.

Embodiment

Illustrate by Fig. 1, a kind of automatic opening-closing time-delay water saving flushing valve, mainly by footstep mechanism 1, water valve 2, spool 3 and installation basis 4 are formed, wherein: by foot panel 11 with anti-skidding line, four panel support axle sleeves 13 and axle sleeve positioning plate 15 are formed footstep mechanisms 1, wherein four panel support axle sleeves 13 are welded to connect with axle sleeve positioning plate 15 and locating piece 16, and become one in the installation basis 4 of packing into, foot panel 11 and four panel support axles 12 are welded to connect, and panel support axle 12 is inserted among the panel support axle sleeve 13 that is placed with panel Returnning spring 14; The valve body 21 of water valve 2 is provided with water intake 22, water outlet 23, and the appropriate location of its water outlet 23 lower limbs is provided with water shutoff mouth dividing plate 28, is shaped on water shutoff mouth 29 on it, and the two ends up and down of valve body 21 are shaped on outside thread; The upper end of poppet shaft 31 is set to the screw bolt-type head and is threaded with foot panel 11 by nut, packing ring with this, its the middle part and the lower end be shaped on outside thread with this by water shutoff piston pad 34 and water shutoff piston retaining washer 35, be threaded with poppet shaft 31, thereby the upper gas sealing piston 32 and the lower seal water piston 33 of rubber material are fixed on the poppet shaft 31, in valve body 21 spaces below lower seal water piston 32 water shutoff piston reset spring 36 are set; Be threaded with the lower end and the upper end of valve body 21 with last sealing nut 24 with lower seal nut 25, going up simultaneously sealing nut 24 is threaded with axle sleeve positioning plate 15, in last sealing nut 24 and lower seal nut 25, be provided with seal rubber pad 27 and lower seal rubber cushion 26, bath time-delay adjusting screw 37 is set on the top of valve body 21, the water intake 22 of valve body 21 is connected with intake pipe 41, and its water outlet 23 is connected with outlet pipe 42.
