Description

Braking, water-saving closed flush toilet

The utility model relates to a kind of flush valve of water-closet, specifically a kind of flushing device that has the variable water tank of displacement that belongs to high-order flushing system.

Existing flushing device for toilet, general water tank is relatively heavier, behind the opening of valves, have only the water of working as a water tank all just can close towards intact, and joint is many, and trouble is installed.

The purpose of this utility model is to provide the high energy-conservation closed flushing device for toilet that a kind of water supply volume is few, can artificially control water supply volume.

Technical solution of the present utility model is:

A kind of braking, the closed flushing device for toilet of economizing on water comprises water tank, water tank communicates with water inlet pipe, the difference of itself and prior art is: water tank upper with in keg float is housed case be tightly connected, ball valve is equipped with on keg float top, the intake and exhaust valve body that is tightly connected with case is equipped with in the ball valve top, the water tank bottom is connected with switch main body, be fixed with piston cavity in the switch main body, the piston cavity inner face contacts with piston body, the outer lug structure of piston body bottom tool, should outer lug structure closely contact with interior lug structure on the switch main body, the piston body endoporus closely contacts with following valve body, spring and spring retention device are equipped with in following valve body top, are equipped with at the corresponding position of switch main body up and down valve body and make the device of valve body deflection down.

On keg float, have anti-stress hole, can reduce stress, anti-overflow pipe also is housed on the intake and exhaust valve body, can prevent that sealing overflows.

Centring ring also is equipped with in the piston body bottom, and when piston body was fallen after rise, position not deflection was askew, can certainly be without centring ring.The device that makes down the valve body deflection is a button, can certainly adopt other suitable construction.Interior lug structure on the switch main body be switch main body itself ledge structure or with the close-connected circulus of switch main body inwall.

The utility model when using, all seal at ordinary times, during water inlet, the inlet and outlet valve cuts out earlier and afterwards continues water inlet, and the interior air of water tank is compressed, the effect of the flow velocity of increase water, minimizing water supply volume when playing out valve in the water tank.The utility model is controlled with hand switch, can control the large and small different water supply volumes just of flushing, presses one day water supply volume of each household three people and calculates: existing flushing device for toilet, about moisture storage capacity 7.5kg;

Flushing stool 3 people take advantage of and take advantage of for 1 time 7.5kg to equal the 22.5kg water yield;

Flushing urine 3 people take advantage of and take advantage of for 4 times 7.5kg to equal the 90kg water yield; Add up to one day water supply volume 112.5kg.

About the utility model moisture storage capacity 6kg;

Flushing stool 3 people take advantage of and take advantage of for 1 time 6 kilograms to equal 18 kilograms of water yields;

Flushing urine 3 people take advantage of and take advantage of for 4 times 3 kilograms to equal 36 kilograms of water yields; Add up to 54 kilograms of one day water supply volumes.

Old-fashioned flushing device for toilet needs because of the installation site, and the down blow mouth is from the about 40-50 centimetre of wall, and the utility model can narrow down to 25 centimeters, has increased the washroom usable floor area virtually.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the configuration diagram of an embodiment of the utility model.

Fig. 2 is the vertical view of piston cavity among Fig. 1.

A kind of braking, the closed flushing device for toilet of economizing on water, water tank 1 communicates with water inlet pipe 2, water tank 1 top with in keg float 3 is housed case 4 be connected, ball valve 5 is equipped with on keg float 3 tops, have anti-stress hole 6(on the keg float or do not open anti-stress hole), ball valve 5 tops and its corresponding site have the intake and exhaust valve body 7 that is tightly connected with case 4, anti-overflow pipe 8(is housed on the intake and exhaust valve body 7 or does not adorn anti-overflow pipe), case 4 tops also are connected with dust cover 10 by nut 9 or other linkages, certainly, also can not add dust cover.Have on the dust cover 10 and the extraneous porting 11 that communicates, the bottom of water tank 1 is connected with switch main body 12, be fixed with piston cavity 13 in the switch main body 12, the inner face of piston cavity 13 contacts with piston body 14, the endoporus of piston body 14 contacts closely with following valve body 15, on the following valve body 15 centring ring 26 is housed also, certainly, also can be without centring ring.Spring 16 and check ring 17 are equipped with in the top of following valve body 15, on switch main body 12, with the corresponding position of following valve body 15 button 18 or other suitable devices that can make time valve body deflection are housed.The outer lug structure 21 of piston body 14 bottom tools, this outer lug structure 21 closely contacts with inwardly protruding shoulder structure 22 on the switch main body.23,24,25 all is sealing rings among Fig. 1.

The course of work of the present utility model is: when water in the water tank proceeds to keg float 3 above positions, water enters from case bottom perforate 27, keg float 3 come-ups, ball valve 5 withstands sealing with the opening of intake and exhaust valve body 7, continue water inlet, water tank upper, the air that does not have to have arranged is contracted by laggard hydraulic pressure, can increase the flow velocity of water when making out valve.Switch is controlled by differential water pressures in plunger shaft 19 and the switch cavity 20, when button is pushed down valve body 15 open, there are one bigger current from plunger shaft 19, to go out, plunger shaft 19 internal pressures descend, piston body 14 is pushed up, and the outer lug structure of piston body is separated with interior lug structure on the switch main body, and current sweep away, when hand left button, following valve body resetted.Piston body is glided by hydraulic pressure and gravity and resets, and current are closed.Water replenishes hydraulic balance in hydraulic pressure and the switch cavity in plunger shaft by switch cavity 20 through piston cavity and piston body contact position in the plunger shaft.
