In conjunction with the accompanying drawings the present invention is further described as follows: this automatic on-off valve comprises and has fluid and advance, outlet 1,2 valve body 3, be provided with the fluid output extending body 4 that points to valve body top in the valve body, have respectively to advance in the upper-end surface of valve body with fluid, outlet 1,2 pressure guide holes that communicate 6,7, valve body top is provided with the valve gap 8 that connects with valve flange, valve gap middle part is provided with choosing that outlet communicates with body cavity to stopcock 10, valve gap and contacting of valve body have on the end face respectively with valve body on pressure guide hole 6,7 match merges the pressure guide hole 12 that communicates to stopcock with choosing, 13, between valve body and valve gap, be fixed with the flashboard that is positioned at fluid output extending body top.At hydrodynamic pressure hour, the present invention's flashboard of being positioned at fluid output extending body top constitutes by steel plate 20 with the fixing rubber 21 of steel plate.When hydrodynamic pressure is big, the flashboard that the present invention is positioned at fluid output extending body top is made of the inner core 5 of steel bar dish one-tenth and the rubber outer 15 of coated inner core, simultaneously, be provided with supporting rib 14 at the inlet of fluid output extending body and with the adjacent space of valve body, be used to cooperate the pressure-bearing of the flashboard of this kind structure at big hydrodynamic pressure situation lower flashboard, steel bar in this flashboard will have certain tightness when the dish knot, make flashboard guarantee certain intensity, simultaneously, also to leave certain free gap, make flashboard have certain flexibility, therefore, during steel bar dish knot suitable tightness will be arranged.For preventing that the inner core that the steel bar dish becomes from getting rusty, and scribbles oiling agent etc. on the steel bar.The inner core of this flashboard also can be become by coil of wire, perhaps by other have certain flexibility, material that again can bearing certain pressure after coiling such as plastic strip etc. coil.For being provided with reinforced layer in the rubber outer of the coated inner core of gaining in strength, the flashboard of this kind structure can be realized the adjusting of rate of discharge.The present invention has selected fluid inlet/outlet valve body in the same way for use, and therefore, the outlet extending body 4 in it is the bending extension body---extension elbow.Fluid inlet and outlet of the present invention is all made flange-like, is convenient to and the connecting of fluid circuit.Its working procedure is as follows: when valve is in closed condition, choosing is to stopcock 10 and pressure guide hole 12,6 communicate, at this moment, the transformation chamber of flashboard top communicates with fluid inlet, the flashboard of outlet extending body inlet and the adjacent space top of valve body partly (rubber in the flashboard of another kind of structure) pressure is identical up and down, and the pressure above the flashboard part (steel plate in the flashboard of another kind of structure) of outlet extending body inlet top is fluid inlet pressure, be outlet pressure below, because inlet pressure is greater than outlet pressure, thereby the inlet that will export extending body compresses, valve closing.When needing Open valve, to select to stopcock Rotate 180 degree, it is communicated with pressure guide hole 13,7, at this moment, the transformation chamber of flashboard top communicates with fluid output, the suffered hydrodynamic pressure in flashboard part (steel plate in the flashboard of another kind of structure) above and below of outlet extending body inlet top is identical, and the flashboard part (rubber in the flashboard of
