Drainage control system is made up of straight tube siphon device and siphon starter.The straight tube siphon device comprises that a top has a bleeder port 10, the bottom is the bell shape parts 11 of four feets 27, and preferably the feet of these bell shape parts can form as shown in Figure 1 tubaeform, and is fixed in water tank 12 bottoms.In bell shape parts 11 bottoms along also being provided with unidirectional guide vane skirt 13 between horn mouth circumferential edge and the water tank bottom, guide vane skirt 13 can only allow water in the water tank 12 from bell shape parts 11 outer flow in cover, and can not allow current direction water tank in the bell jar.Bell shape parts 11 central authorities also are provided with the less gutter of a diameter 14, and the one end is fixedlyed connected with a pipe (not shown) that leads to water closet at outfall 30 places of water tank bottom, forms a drainage channel; Preferably, the bottom of gutter 14 is the taper of a flaring, and forms straight-run of pipe pressing close to the outfall place, so as with a pipe welding of leading to water closet, and form the outfall of a preferable convergent flaring, so that drainage effect strengthens.In the utility model, the ratio range of the internal diameter of bell shape parts and gutter internal diameter is 2: 1 to 2.4: 1, and wherein the inlet of gutter 14 should exceed 1 to 2 centimetre of the H0 water surface.

Siphon starter in the drainage control system is to be used for triggering the hydrocone type draining.This siphon starter comprises the sealing water vat 19 (seeing Fig. 1 and Fig. 2) that is communicated with bell shape parts 11 first halves, one floating plug 20 is arranged in water vat 19, floating plug 20 upper ends link to each other with a drive link 21, drive link 21 is driven by a crank 22, crank 22 1 ends are fixed in water tank 12 walls 23 places, the other end is fixed in by a supporting walls 24 places of stretching out on the water vat, that end that crank 22 is fixed on the water tank wall also links to each other with the outer one handle 25 of water tank, for the ease of operation, also can fasten a stay cord 26 on the handle 25.Under the state shown in Figure 1, drainage control system also is in the balance dormant state, and this moment, bell shape parts 11 and siphon starter water vat 19 interior water levels all were in H0, and floating plug 20 is positioned on this water level.

Preferably, in use can regulate washing water quantity according to actual conditions in order to make the utility model flushometer, a displacement setting apparatus also is provided in the drainage control system, this setting apparatus can be used to set the water yield that the siphon device draining is gone out.Setting apparatus comprises a rotary nut regulated 15 that is contained on the tank lid 31, the screw rod 16 that screws togather with nut 15, screw rod 16 also screws togather with a binding nut 18 in tank lid, the lower end of screw rod is connected with an aciculiform spool 17, and this aciculiform spool 17 can insert in the bleeder port 10 on the bell shape parts 11.Clockwise direction rotating screw cap 15, screw rod is moved down and drive the aciculiform spool and block bleeder port 10 gradually, counterclockwise rotary nut then makes and moves on the screw rod 16 and drive the aciculiform spool and leave bleeder port 10 gradually, and the former causes displacement to increase, and the latter reduces displacement.

Below the course of work of flush toilet flushometer of the present utility model is described in detail.

Referring to shown in Figure 1, the state of flushometer shown in the figure is stand-by equilibrium state.Pulling handle 25, can force crank 22 descending, thereby make in the bell shape parts 11 that floating plug 20 pushes the water in the water vat 19 to be communicated with it to, owing to be provided with a unidirectional blade skirt 13 between bell shape parts 11 bottoms and water tank 12 bottoms, make the water in the bell shape parts 11 can't flow out bell jar like this, thereby the water that the bell jar headroom is discharged in the water vat occupies, drain air and promptly flow to gutter 14, and triggering siphon drainage process, it is the current process bell shape feature bottom in the water tank, through unidirectional blade skirt, gutter row is in the pipe at water closet place, and flushing closestool.Because this moment, the water in the bell shape parts not only is subjected to the effect of height of water level, but also because the effect of pressure reduction between the atmospheric pressure on the water surface in interior vacuum of bell jar and the water tank, so water velocity is very fast.In addition, be actually because the bell shape parts generation siphonage of straight pipe type, and be different from bend pipe siphonage in the prior art, reduced flow resistance so the flushing dynamics is strengthened, simultaneously because the bell shape parts of straight pipe type, gutter etc. have substituted traditional pull-type draining valve, thereby the dislocation of having avoided may occurring in the dynamic operation of drain plug coincide with delivery port and does not sternly reach because of the valve seat distortion, corrodes the defectives such as clearance leakage that cause.

After draining began, water level H0 descended, and the water level in the float chamber 8 in the water inflow control system is higher than the water level in the water tank, and this moment promptly can be by syphon 9 to cistern water-discharging.Syphon 9 draining at the beginning, the ball float 6 in the float chamber 8 promptly descends, and lever 7 descends and takes baffle plate decline to, and nozzle is opened, and begins water inlet.Because the volume of water is less than the water yield in the water tank far away in the float chamber 8, thus the emptying apace of the water in the float chamber, and make ball float be in extreme lower position, nozzle is opened at utmost.As long as H0 continuously descends, nozzle promptly can continuously be sprayed water, in case the drawdown of water tank 12 is to desired location (this position is set by the draining setting apparatus), then drainage procedure promptly automatically finishes, and maximum water inlet process can last till that water level drops to after the extreme lower position of setting and goes back up to the height of a little higher than H0.At this moment, because water tank 12 water levels are far above the water level in the float chamber 8 of emptied of water, thereby caused syphon 9 siphonage and rapidly to float chamber's 8 water fillings, aqueous reflux in the water tank is in float chamber 8 independently, make float chamber's water level return to H0 and make ball float get back to original position, raise lever 7 and on baffle plate 4, and jet expansion shut, making into, water stops.As seen, whole draining, water inlet process, particularly the process of ball float cut-out nozzle jet is quicker more than the action of common nozzle and ball float.

Below in conjunction with a preferred embodiment flush toilet flushometer of the present utility model has been made detailed description.Yet, those of ordinary skill in the art is appreciated that, only otherwise break away from essential scope of the present utility model, can also make further improvement to this embodiment, for example at the close flexible sheet place of the upper chamber of pressure feedback formula flow control valve one spout hole 106 can be set also as shown in Figure 3, allowing the empty G﹠W that infiltrates in the upper chamber can be from flowing out, thereby prevent from the distortion of flexible sheet is had a negative impact; In addition, between spool and valve seat, also can be provided with spool leakproof glue ring 104, be used for preventing that the water of T shape water stream channel is owing to pressure leaks out in the upper chamber.In addition, though the flow control valve shown in the figure is placed to water inlet pipe up, also can flow control valve be placed to water inlet pipe be positioned at the below according to actual conditions.Therefore, protection of the present utility model should be determined by appended claims.
