Describe the utility model in detail below in conjunction with accompanying drawing and specifically install details, working condition and using method:

As depicted in figs. 1 and 2: flap 14D shape seal ring 13 goes out closed condition with valve barrel 18 lower end flared hole 12 among the figure, this use new device has using method in two: a kind of is multi-stage self controlling, the small-large flow long-time continuous water operating method of following one's bent, need only be during use with handle 1 rotation or switching counterclockwise, the flow position-limited claw 7 that protrudes by handle 1 lower end endoporus glides step by step along spacing oblique chute 8 water yields of valve barrel (as shown in Figures 2 and 3) top cylindrical flow are ascending.Forcing handle 1, valve rod 3, piston 17, flap 14 straight lines to descend to throw off water flowings automatically with the flared hole 12 of valve barrel 18 lower ends can the continuity water, clockwise cycle or turn back handle 1 and close automatically immediately to stop; Another kind is the time-delay quantitative automatic turn-off, the operating method of short time discontinuity water: must handle 1 top need only not pushed downward vertically the flow position-limited claw 2 of a lower handle 1 lower end endoporus protrusion along spacing vertical chute 24 declines of the flow of valve barrel (as shown in Figures 2 and 3) top cylindricals by handle with sleeve 1 during use, the quantitative water of can delaying time, use and uprightly behind institute's setting up time close automatically, its details and working condition are: when depressing handle 1, flared hole 12 is thrown off automatically under valve rod 3 pistons 17 piston cups, 9 flaps 14 and the valve barrel, the water route is open-minded, depress handle 1 this in a flash, because piston cup 9 when descending, just produces negative pressure (vacuum) in the valve barrel 18 press water cylinder barrels in valve barrel 18.At this moment water inlet divides three the road to flow to, big portion current flow out the water outlet of valve body 15 by valve barrel bottom water channel 16, part current are owing to be subjected to the suction function in the valve barrel press water cylinder barrel to pass stem lower portion flowing hole 21 suction valve barrels 18 press water cylinder barrels from piston bottom flowing hole 11 by the gap, limit between piston tip center resistance hole 20 and the timing pin 6, another part current are simultaneously because of being subjected to suction function in the valve barrel 18 press water cylinder barrels to send the gap between piston 17 bottom minimum outer diameter and the valve barrel 18 bottoms minimum endoporus and the gap of piston cup 9 and valve barrel 18 press water cylinder barrel inwalls to suck in the cylinder barrel simultaneously, when two-part current that suck are full of cylinder barrel, because flowing out with the atmosphere perforation from water outlet, most of current promptly formed malleation, to be advanced the guiding of the promotion of water kinetic pressure and spring 2 simultaneously down auxiliary in the bottom plane of snap ring 10 under the bottom plane of flap 14 and the piston cup conversely, it is vertically up to promote valve rod 3 pistons 17 flaps 14, speed that it is up or bottom that can the up valve barrel of hand again 18 press water cylinder barrels, because the smooth water resistance size that two-part current that the effect of negative pressure sucks have been full of in the valve barrel 18 press water cylinder barrels restricts, because when pushing handle 1, piston cup 9 is forced into the bottom of valve barrel 18 press water cylinder barrels, because two-part current that the effect of negative pressure sucks have been full of valve barrel 18 press water cylinder barrels, the finger release handle 1 of pushing handle 1 this in a flash, piston cup 9 has been subjected to the influence of smooth water resistance in the cylinder barrel again, force the maximum open of its piston cup 9 to expand outwardly to be adjacent to and sealed the bottom of cylinder barrel with inner wall of cylinder, valve barrel water seal 5 has sealed up the cylinder barrel top again, the relative up and down sealing in top with the bottom, wanting row, to unload in the cylinder barrel smooth water resistance be that piston cup 9 reduces resistance and speed uplink (delay time) when up, just must suitably adjust the gap, limit (being area of passage) between timing pin 6 and the piston tip center resistance hole 20, otherwise, water in the valve barrel 18 press water cylinder barrels can't be got rid of, cause piston cup 9 top smooth water resistances greater than the bottom hydrodynamic pressure, making the piston skin play 9 flaps 14 can not be up, valve can not be closed automatically, that is to say, time-delay quantitatively discharges water, the time length of closing automatically, the speed of speed uplink will be realized by the difference of adjusting between piston cup 9 top smooth water resistances and the bottom hydrodynamic pressure, as timing pin 6 clockwise directions are stirred, its needle point rises and piston tip center resistance hole 20 is thrown off the generation gap automatically, row unloads the smooth water resistance in the piston cup 9 top cylinder barrels, make its top smooth water resistance less than the bottom hydrodynamic pressure, form a tangible pressure difference, water in the cylinder barrel is under the promotion that is subjected to snap ring 10 bottom plane hydrodynamic pressures under flap 14 bottom planes and the piston cup, piston cup 9 is up, force the water in the cylinder barrel to be got rid of to water outlet by the gap, limit and the piston bottom flowing hole 11 of stem lower portion flowing hole 2 piston tip center resistance holes 20 again conversely, in other words, the gap of adjusting between timing pin 6 and the piston tip center resistance hole 20, limit is big more, area of passage is just big more, water row in the cylinder barrel unloads just fast more, resistance when piston cup 9 is up is just more little, the up speed of flap 14 is just fast more, time that time-delay discharges water and the time of closing automatically are just short more, otherwise, flap 14 speed uplinks are just slow more, time-delay discharge time and automatic shut-in time are just long more, up to flap D shape seal ring 13 is fitted sealing with the flared hole 12 of valve barrel lower end till, promptly close automatically, finish a work cycle.

The utility model device can be manufactured household type and public type two big class series product, (quantitatively time-delay and automatic shut-in time all can be adjusted voluntarily), its difference is: the household type product both can have been pushed the handle quantitative water of delaying time and close automatically, can rotate again or the switching handle small-large flow continuous water of following one's bent, not only using water wisely but also can satisfy the requirement of domestic water: public type product can only be pushed the handle quantitative discontinuity water of delaying time and close automatically, it is motionless that handle changes, impossible running water forces people's using water wisely in public places.

Various zero (portion) parts in the utility model all adopt general versatile material such as cast copper, zinc alloy, engineering plastics, stainless steel, rubber, plating Lip river and general manufacturing process, no specific (special) requirements, and conventional machinery process equipment and unskilled labor can be realized per capita.
