Description

Laborsaving draining valve

Technical field

The utility model relates to the draining valve in a kind of water tank, relates in particular to the draining valve that a kind of gradation is opened.

Background technology

Consult Fig. 1, Fig. 2, Fig. 9, Figure 10, existing common turnover plate type draining valve and top uncoupling type draining valve, all only has a valve plate 6, the disposable valve plate 6 of opening when draining, but when the relatively high valve plate 6 of the water level in the water tank is quite large again, because the pressure of water, open valve plate 6 just needs sizable power; Such as the draining valve in existing toilet seat water tank, progress along with the water closet water-saving technology, draining valve in the present new water-saving water tank of closestool is all large than old-fashioned, be valve plate 6 larger than old-fashioned, and row's all is the interior small part water of water tank, most of water also remains in the water tank, also be that the interior water level of water tank is also than old-fashioned height, although the result of this design has economized on water, but also brought new problem, the power of pressing exactly the draining button in the time will washing by water will be bigger than normal, and child and aging old man just might be by motionless.

The utility model content

The purpose of this utility model is to provide a kind of laborsaving draining valve of gradation startup.

To achieve these goals, the laborsaving draining valve that the utility model provides is characterized in that: valve seat, little valve plate, large valve plate are arranged, large outfall is arranged on the described valve seat, little water shutoff film is arranged on the described little valve plate, large water shutoff film, little outfall, interlock body are arranged on the described large valve plate;

Described little valve plate is installed on the described large valve plate, and described little water shutoff film covers on described little outfall;

Described large valve plate is installed on the described valve seat, and described large water shutoff film covers on described large outfall;

When draining, described little valve plate at first is activated, thereby make described little water shutoff film be separated from described little outfall, after described little valve plate moves a bit of distance, described little valve plate drives described interlock body, thereby described large valve plate is activated, also makes described large water shutoff film be separated from described large outfall.

The beneficial effects of the utility model are: can light startup draining.

The specific embodiment

The specific embodiment one

Consult Fig. 3, at little valve plate 1 little water shutoff film 2 arranged, lift post 3, little valve plate rotating fulcrum position 5, backguy hole 4 is arranged lifting post 3;

Consult Fig. 4, at large valve plate 6 little valve plate rotating fulcrum position 5, large water shutoff film 7, the float mouth of a river 8, large valve plate rotating fulcrum position 11, interlock body 9 are arranged, at interlock body 9 linkage post 10 is arranged;

Consult Fig. 5, at valve seat 12 large valve plate rotating fulcrum position 11, large outfall 13 are arranged;

Consult Fig. 6, little valve plate 1 is installed on the large valve plate 6, large valve plate 6 is installed on the valve seat 12, one end of backguy 14 is fixed on the backguy hole 4, when little valve plate 1 is all closed with large valve plate 6, little water shutoff film 2 covers on the float mouth of a river 8, and large water shutoff film 7 covers on large outfall 13, and little valve plate 1 is below linkage post 10;

Wherein, little valve plate 1 can be along little valve plate rotating fulcrum position 5 rotates, and large valve plate 6 can be along large valve plate rotating fulcrum position 11 rotates;

Consult Fig. 7, when pulling backguy 14 draining, little valve plate 1 is 5 rotations along little valve plate rotating fulcrum position, be that little valve plate 1 at first is activated, little water shutoff film 2 is separated from the float mouth of a river 8, after little valve plate 1 rotates a bit of distance, little valve plate 1 will drive linkage post 10, also namely drives interlock body 9;

Consult Fig. 8, continue pulling backguy 14, large valve plate 6 just rotates along large valve plate rotating fulcrum position 11 together along with interlock body 9, thereby large valve plate 6 is unlocked, and large water shutoff film 7 is separated from large outfall 13, and large outfall 13 is all opened.

The specific embodiment two

Consult Figure 11, at little valve plate 1 little water shutoff film 2 arranged, lift post 3;

Consult Figure 12, at large valve plate 6 large water shutoff film 7, the float mouth of a river 8, interlock body 9 are arranged, at interlock body 9 linkage post 10 is arranged;

Consult Figure 13, at valve seat 12 large outfall 13, limit body 15, limited post 16 are arranged;

Consult Figure 14, little valve plate 1 is installed on the large valve plate 6, and large valve plate 6 is installed on the valve seat 12, and when little valve plate 1 was all closed with large valve plate 6, little water shutoff film 2 covered on the float mouth of a river 8, and large water shutoff film 7 covers on large outfall 13;

Wherein, little valve plate 1 can move up and down along interlock body 9, and large valve plate 6 can move up and down along limit body 15;

Consult Figure 15, when on when lifting post 3 draining, little valve plate 1 moves up along interlock body 9, be that little valve plate 1 at first is activated, little water shutoff film 2 is separated from the float mouth of a river 8, and little valve plate 1 moves up after a bit of distance, little valve plate 1 will drive linkage post 10, also namely drives interlock body 9;

Consult Figure 16, lift post 3 in the continuation, large valve plate 6 is just along with interlock body 9 moves up along limit body 15 together, on move to certain altitude and run into behind the limited post 16 and to move on can not be again, thereby large valve plate 6 is unlocked, and large water shutoff film 7 is separated from large outfall 13, and large outfall 13 is all opened.

In the situation that water level is identical in the water tank, the suffered pressure of valve plate is determined by the effective lifting surface area that valve plate is subject to, when opening little valve plate 1, large valve plate 6, because effectively lifting surface area has reduced, so also relatively laborsaving, essence of the present utility model is that a total power has been divided into secondary opening in fact.
