Describe details using method and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes:

As shown in Figure 1: the utility model device has two kinds of usings method: a kind of is the indiscriminately ad. as one wishes continuous water operating method of no stage self-regulating, small-large flow, must pressing button (1) during use knob (2) counterclockwise need only not rotated the bellmouth orifice (16) that force the descending and middle seat of button (1) and valve rod (5) plunger (12) flap (14) lower end and throw off water flowing automatically and get final product continuous water, forward knob (2) be rotated back into stop and promptly close; Another kind be delay time quantitatively, close automatically, the operating method of discontinuity water, must button (1) need only not cut out automatically to pressing down the quantitative water of can delaying time by turning knob (2) during use, descending when press push button (1) valve rod (5) plunger (12) U-shaped thrust ring (10) flap (14) while, O-ring seals in the flap (15) is thrown off automatically with middle seat lower end bellmouth orifice (16), and the water route is open-minded.Press push button (1) this in a flash, because U-shaped thrust ring (10) is in middle seat (8) endoporus compression water vat when descending, just produce negative pressure (vacuum) in the compression water vat, at this moment water inlet divides three the road to flow to, most of current flow to the water outlet of valve body (13) by middle seat water port, bottom (18), a part of current since by compression the suction function in the water vat pass across discharge orifice (17) from the plunger middle part and pass flowing hole (20) suction that stem lower portion crosses by the gap, limit between the end toper needle-valve (21) under plunger upper end center resistance hole (19) and the timing bolt and compress water vat, another part current simultaneously because of the suction function in the compression water vat from plunger (12) bottom minimum outer diameter with the gap of gap between the minimum endoporus in seat (8) bottom and U-shaped thrust ring (10) and the pressurized water inside wall of cylinder suck simultaneously and compress in the water vat, when two-part current that suck ooze full compression water vat, because flowing out with the atmosphere perforation from water outlet, most of current promptly formed malleation, the bottom plane of the bottom plane of flap (4) and following snap ring (11) is assisted down by the promotion of intake pressure and the guiding of spring (4) simultaneously conversely, it is up to promote valve rod (5) plunger (12) flap (14), its up speed and can be up again by compression the smooth water resistance size in the water vat restrict, because in pressing button (1), U-shaped thrust ring (10) is forced into the bottom of compression water vat, because effect two-part current of negative pressure are inhaled in the compression water vat, the finger release button of pushing this in a flash, U-shaped thrust ring (10) is the smooth water resistance in the water vat by compression again, force the maximum open of its U-shaped thrust ring (10) outwards to be put to open and be adjacent to the pressurized water inside wall of cylinder and sealed the casing wall of pressurized water cylinder bottom portion, M shape water seal (7) has sealed up the top of compression water vat again, the top, the relative up and down sealing in bottom, want to arrange and reduce resistance or speed uplink when the smooth water resistance of unloading in the pressurized water cylinder makes U-shaped thrust ring (10) up, just must suitably adjust under its timing bolt the gap, limit (being area of passage) between the center resistance hole (19) on the end toper needle-valve (21) and plunger, otherwise the water in the compression water vat can't be got rid of, to making U-shaped thrust ring (10) top smooth water resistance greater than the bottom hydrodynamic pressure, make U-shaped thrust ring (10) flap (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 smooth water resistance in adjustment U-shaped thrust ring (10) the top compression water vat and the pressure difference between the hydrodynamic pressure of bottom, as timing bolt (3) clockwise direction is stirred, timing bolt lower end awl hand-manipulating of needle valve (21) rises and automatic disengagement of plunger upper end center resistance hole (19) produces the gap, row unloads the smooth water resistance in U-shaped thrust ring (10) the top compression water vat, make its top smooth water resistance less than the bottom hydrodynamic pressure, form a tangible pressure difference, water in the compression water vat is under the promotion that is subjected to flap (14) bottom plane and following snap ring (11) bottom plane hydrodynamic pressure, U-shaped thrust ring (10) is up, forcing the water of compression in the water vat to pass across the gap, limit of discharge orifice (20) plunger upper end center resistance hole (19) and plunger middle part by stem lower portion again conversely passes across discharge orifice (17) and gets rid of to water outlet, in other words, the big more area of passage in gap, limit under the adjustment timing bolt between end toper needle-valve (21) and the plunger upper end center resistance hole (19) is just big more, smooth water resistance in the compression water vat is just more little, resistance when U-shaped thrust ring (10) is up is just more little, the up speed of flap (14) is just fast more, time-delay discharge time and the time of closing automatically are just short more, otherwise, the up speed of flap (14) is just slow more, time that time-delay discharges water and the time of closing automatically are just long more, O-ring seals (15) in flap (14) is fitted with middle seat lower end bellmouth orifice (16) till the sealing, promptly close automatically, finish a work cycle.

The utility model in use, as the short time such as gargling, clean fruit of washing one's hands, wash one's face, brush teeth is during a small amount of water, must not stir knob (2) need only be with button (1) vertical depression once, can delay time and quantitatively discharge water, automatically close that (time-delay discharge time user can arbitrarily adjust, generally transfer to and fill one glass of mouthwash of brushing teeth, about 3-5 is advisable second, water-saving result the best).During as the continuous water of need, must knob (2) counterclockwise need only not rotated (as using spiral tap) by pressing button (1), the flow size, service time length, needs according to the user are followed one's bent, no stage self-regulating uses up the back clockwise direction and knob (2) is rotated back into stop promptly closes automatically.

The utility model is in order to carry out the belt-tightening water in public places, stop the running water phenomenon, divide equally public type and household type two big classes with the series product that this device is made, its difference is: be suitable for for convenience, not only button (1) is housed but also knob (2) is housed in the household type product, button (1) is enclosed among the knob (2), not only can delay time that the discontinuity water is closed automatically but also water continuously, small-large flow is followed one's bent, no stage self-regulating.Public type product only is equipped with button (1) the quantitative water of can only delaying time closes automatically, can not running water, and the people is for being not related to its automatic pass, thereby reached the purpose of belt-tightening water.
