Description

A kind of water-saving water tank drain valve

The utility model relates to a kind of living facilities articles for use, particularly a kind of lavatory, the water-saving water tank drain valve of lavatory flushing.

Lavatory, lavatory flushing water tank are public place and the requisite sanitary fittings of huge numbers of families' family life, and draining valve then is the main element that wherein plays a crucial role.At present owing to structural reason, drainage control mechanism and passage that normally used water tank drain valve is made of pull bar, backguy, gutter can't be according to waiting to wash the large and small displacement of how much controlling that just waits amount of contaminants, thereby in case spur pull bar, the cover plate on the gutter is just drawn back in the backguy that is attached thereto, water in the case is all put only, caused a large amount of wastes of water.

The purpose of this utility model be to provide a kind of can be according to waiting to wash how many water-saving water tank drain valves of rationally making water supply volume, avoiding waste of dirt.

The utility model is to realize like this.This kind draining valve by gauge tap, pull bar, backguy, ball float, overflow pipe, set upright pipe, gutter, cover plate, water inlet pipe and form, its structure, assembling feature are as follows: gauge tap is inboard to fuse with pull bar, the outside is fixed on the outer wall of water tank the place ahead, and indicates scale and " one grade ", " second gear " printed words; Penetrate backguy respectively in two eyelets of pull bar front end, two backguy other ends are connected with the upper and lower two-layer cover plate of gutter respectively; The gutter upper outside has picked out overflow pipe, and overflow pipe is set with outward sets upright pipe; The tipping of water inlet pipe top has and connecting rod all-in-one-piece ball float.This water-saving draining valve and normal discharge valve are installed in the water closet equally.During use, according to dirt what, gear selecting arbitrarily, when amount of contaminants after a little while, gauge tap is pulled one grade, at this moment, the backguy that pull bar front end apertura lateralis is connected promptly is pulled up, the cover plate of upper layer that is attached thereto is opened, the water that is positioned at this cover plate top in the water tank enters gutter from the mouth of pipe that opens wide and discharges, and dirt is washed away thereupon.After the water more than the upper cover plate of upper strata had been arranged, because action of gravity, cover plate of upper layer covered automatically, thereby remaining water is just stayed in the water tank in the water tank, reaches the water saving purpose.If amount of contaminants is big, then switch can be pulled to second gear, at this moment, the pull bar front end outside backguy that eyelet connected before this is pulled up, and drive backguy cover plate of upper layer is opened draining, then, the backguy that the inboard eyelet of pull bar front end connects is pulled lower floor's lid again and is opened, can the water in the water tank all be washed away, dashed the upper and lower cover plate in back and promptly successively covered by deadweight.

The utility model modern design, rational in infrastructure, easy to use, utilize it to reach reasonable use of water, water-saving purpose according to how many gear selectings of waiting to wash dirt.The water-saving draining valve of this kind is especially outstanding for the water-deficient area Practical significance.

Accompanying drawing is a general structure schematic diagram of the present utility model.Among the figure, label " 10 " is a water tank.

Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.

As shown in the figure, the utility model by gauge tap 1, pull bar 2, backguy 3, ball float 4, overflow pipe 5, set upright pipe 6, gutter 7, upper and lower layer cover plate 8, water inlet pipe 9 and form, except that backguy 3, cover plate 8, other component adopt plastic production mostly, wherein, gutter 7 is a bend pipe that is made of upper and lower two upright pipe sections and the middle square pipeline section of level, becoming vertically upright installs, two upright pipe sections upper end is uncovered, and last vertical section pipe upper outside has and is used for the square aperture that is communicated with overflow pipe.Upper and lower layer cover plate 8 is the plectane of diameter greater than the uncovered diameter in gutter 7 liang of upright pipes upper end, make of soft rubber, can cover the mouth of pipe completely under the action of gravity of water above it, the one side is provided with connector, can be separately fixed on overflow pipe and the gutter after penetrating fixed bar in the eyelet of both sides.Overflow pipe 5 middle parts are that central authorities have the rectangular platform that circular hole, both sides are respectively set up 2 upright trapezoidal righting boards separately, center hole below be a upper end band negative thread and on connect the pipe section that the upright pipe of portion, both sides are provided with brace rod, pipe section below is the square pipeline section of level that links to each other with vertical section square aperture on the gutter.Setting upright pipe 6 is the short tube that an internal diameter is a bit larger tham the overflow pipe external diameter, be provided with to bilateral symmetry extension bar before and after it, be used to embed in the upright clip slot between the trapezoidal righting board in overflow pipe both sides, middle part, setting upright pipe can move up and down in this clip slot scope, and overflow pipe is played centralizing function.All the other each component structurals and existing finished parts are roughly the same.
