Abstract

The utility model relates to a water saving type drainage valve for the water tank of a toilet, which has the purposes of adjustable drainage amount and water saving. The utility model is mainly characterized in that a water discharge opening in a vertical rod (1) is provided with a valve (2), an up and down adjustable positioning support arm (5) is assembled on the vertical rod (1), the upper part of a draw rod (3) on a floating ball type valve (2) passes through the extending end of the positioning support arm (5), and an up and down adjustable counterweight box (4) is assembled on the draw rod (3). The utility model has the advantages of simple structure, convenient installation and use under the condition that the original water tank structure is not changed, adjustable water discharge amount, high leakage-proof performance and water saving.

Description

The water-saving draining valve of toilet tank

The utility model relates to the water-saving draining valve of toilet tank.

In background technology, the sanitary equipment water tank of Xiao Shouing has high-order water level and low water stage water tank in the market, adopt bat to cover form valve or employing ball float form valve on the draining valve doorway, after the water tank filled with water, in the time of need washing away just, the artificial employing pulls rope, or rotary handle, or form such as elastic button lifts to clap and cover valve or ball valve rising, valve open, whole box water is gone out, along with drawdown when the draining valve doorway, clap and cover valve or float valve and also descend and block valve port, water tank begins water storage again, water intaking valve is closed when extremely expiring, and is in state to be discharged water again.In case its weak point is to wash by water then whole box water is gone out, and in actual applications, can not regulate discharging quantity of water, relatively water wasting.

The purpose of this utility model is the water-saving draining valve of a kind of toilet tank of development, and it is adjustable to reach displacement, can economize on water purpose easy to use.

Technical solution of the present utility model is as follows:

Comprise: there is up and down valve 2 at the outfall place in the vertical rod 1, the adjustable support arm 5 of locating up and down of assembling in the vertical rod 1, and pull bar 3 tops on the float-ball type valve 2 is characterized in that by location support arm 5 external parts: the adjustable counterweight box 4 up and down of assembling on the pull bar 3.

Comprise: the hinged bat lid formula valve 2 to be opened/closed in outfall place in the vertical rod 1, it is characterized in that: clap the pull bar 3 that covers adjustable length on the formula valve 2 and connect counterweight box 4, up and down counterweight box 4 is assemblied in the vertical rod 1.

Description of drawings of the present utility model is as follows: Fig. 1 is a float valve gate-type structural representation, and Fig. 2 claps cap valve formula structural representation.

Following adjoint is described in further detail: referring to Fig. 1, there is float-ball type valve 2 at outfall place in vertical rod 1, valve 2 upper end steady braces 3, pull bar 3 tops are by location support arm 5 external parts, work the orientation that moves up and down, in the support arm 5 usefulness screws assembling vertical rod 1 of location, height is adjustable, and this is existing in the background technology.By the adjustable counterweight box 4 up and down of spiral shell mosquito connection form assembling, this is a design feature, plays the effect that the water yield is emitted in control on pull bar 3.The course of work is like this, according to circumstances adjust the height of location support arm 5 and the height of counterweight box 4, when the need minimum amount is washed away, through turning handle or stay cord, pull bar 3 lifts, open water on the valve 2, along with water level reduces, valve 2 falls adhesive and closes the mouth of a river, and water intaking valve is opened (not drawing among the figure), and water storage is to former water level again.When need washed away than big yield, through turning handle or stay cord, hand did not unclamp, and kept valve 2 to be in the lifting state, opened the mouth of a river always, and how much what institute's moisture storage capacity continuous erosion, the water yield were emitted is directly proportional with lifting 3 duration of pull bar, and emitting the water yield is at most whole box water; Simultaneously, because deadweight increases, valve 2 is closed the suction-combining force also to be increased, and has improved the ability of preventing water drip.Referring to Fig. 2, the hinged valve 2 that can fall of opening in place, vertical rod 1 dewatering outlet, being valve 2 right sides of clapping the form of covering has a rope hole, the assembling stay cord, these are existing in the background technology.Hinged adjustable length pull bar 3 on the valve 2, the hinged counterweight box 4 in pull bar 3 upper ends, counterweight box 4 is set in the vertical rod 1, can move up and down, and this is characteristics of the present utility model.If rope is positioned at the effect that also can realize opening and closing valve 2 on the counterweight box 4.Operating principle and process are adjusted pull bar 3 certain-lengths with Fig. 1 unanimity, and when lifting valve 2, open at the mouth of a river, discharge water and wash away, and along with drawdown arrives to a certain degree, valve 2 falls adhesive, and emit the water yield this moment is minimum amount; When lifting valve 2 when being in persistent state, valve 2 continues to open, and washes away the water yield and opens time length with valve 2 and be directly proportional, and the water yield is at most that whole box water washes away, and has in like manner also realized the ability of preventing water drip.

Advantage of the present utility model and effect are as follows:

1. owing to adopt counterweight box, historical facts or anecdotes has showed adjusts emitting of the different water yields, has saved water.

2. simple in structure, under the structural condition that does not change original sanitary equipment, be easy to realize that old-fashioned toilet is clean The transformation on economy of water cousumption of tool water tank just can be controlled waterdrainage amount, saves a large amount of waters, and easy to use.

3. the utility model valve closes performance improves, and has reached the purpose that prevents water dripping.
