Abstract

The utility model relates to a water saving leakproof drain valve for a cistern, which belongs to a component of a sanitary ware. The utility model which relates to a drain valve for a low level cistern or a high level cistern of a water closet is characterized in that a water sealing device (a valve core) in a shape of a cup carries out conical fit with a water outlet, and the water sealing device carries out lifting in a leak hole cover and can be used of a pulling and drawing type or a wire drawing type. The utility model which can control the quantity of water draining at will according to demands has the advantages of convenience, labor saving, good water sealing effect, good leakproof effect, and distinct water saving effect. The drain device which can cause the reduction of the volume and the weight of the cistren has the advantages of simple structure, and material saving. The utility model provides convenience and benefits for manufacture, transportation, and users.

Description

Water saving leakproof water tank drain valve

The utility model water saving leakproof water tank drain valve is the accessory on the sanitaryware, is the draining valve that closet low level cistern or high level cistern are used.It is characterized in that, up and down in the cup-shaped small opening cover that is enclosed within on the outfall of water shutoff device (spool), be circular cone with outfall and cooperate water shutoff, one elastic force apparatus that the water shutoff device is resetted is arranged on the water shutoff device and between the small opening cover, push away the towed startup water shutoff of the mode of pulling out or backguy device, easy to use laborsaving, the water shutoff leak preventing effect is first-class, and can arbitrarily control displacement, water-saving result is remarkable.

Prior art is controlled bulb stopper or turnover panel water shutoff with the handle lever construction, but effect is desirable not to the utmost sometimes, and the contact surface of water shutoff is narrow, and not fitting slightly will water skiing.And complex structure, the expense of taking a lot of work material uses effort and inconvenient, and people often are confused about and just pull still counter pulling.Maximum problem is arbitrarily to control displacement as required, one to pull be exactly one case water, and do not need the number of times that just can deal with problems with one case water more much more in the daily life than number of times with one case water, but all have to give with one case water, the waste that causes therefrom is considerable! at every turn

The purpose of this utility model is: a kind of anti-skidding water tank drain valve of water saving of new construction is provided, and easy to use laborsaving, water shutoff device (spool) accurate placement, the water shutoff leakproof is tight, and can arbitrarily control displacement on demand, with more using water wisely; Another purpose is to reduce the number of mechanism, for dwindle the water tank volume, weight reduction creates conditions, and saves labor and materials, reduces cost.

The utility model is to realize (being explained as follows in conjunction with the vertical profile schematic diagram) like this:

With the material that satisfies the function needs, the water shutoff device of making cup-shaped interior middle band lattice is circular cone with the valve body outfall of making and cooperates, adorn a small opening cover on the outfall, establish an elastic force apparatus between water shutoff device top and the slide opening cover, perhaps on the water shutoff device, establish a puller system with small opening cover root, can be after the water shutoff device is promoted from horizontal reset.

The mode of occupation of draining valve has three: push away the formula of pulling out as it (one) among the figure, open a hole and penetrate a metal or the plastics stiff rod on the tank lid of outfall center correspondence, the following company connects handle on the water shutoff device, pull out the water shutoff device for pushing away; They (two) revolve wushu, connect pull rope at water shutoff device center, be connected with handle connecting rod on the water tank wall by the fixed pulley that turns to that is located at slide opening cover upper end, handle is rotated in spacing forward or backwards can both affect the water shutoff device to rise, the handle rotational angle is directly proportional with water shutoff device rise amplitude, and the water shutoff device resets under the elastic force apparatus effect immediately during the stressed disappearance of handle; (3) be the drawing-type that is used for high level cistern, make the pull rope that links the water shutoff device, limit to extend downwards after the suitable length and connect operating handle by the turning to behind the fixed pulley of slide opening cover top again by being located at the pulley of high level cistern sidewall.

Accompanying drawing is a water saving leakproof water tank drain valve vertical profile schematic diagram.1 is handle among the figure; The 2nd, tank lid; The 3rd, pulley; The 4th, push away dead man (or pull rope); The 5th, the small opening cover; The 6th, elastic force apparatus; The 7th, the water shutoff device; The 8th, outfall; The 9th, valve body; The 10th, at the bottom of the water tank.

Compared with the prior art the utility model has the following advantages:

1, because sealing device for outlet and discharge outlet are Cone fit, have enlarged sealing surface, and be to be controlled in the small opening cover to rise Fall, and elastic force apparatus is arranged, this sealing device for outlet is filled with water such as cup in addition, and the gravity of water, pressure and pipe negative pressure effect all can Make Cone fit tightr, thereby both guaranteed that sealing device for outlet in time resetted, accurate placement, water shutoff is tight, has solved The water skiing problem.

2, since present technique push away arbitrarily ACTIVE CONTROL sealing device for outlet heave amplitude and when resetting of the formula of pulling out or mode of traction Between, thereby can arbitrarily control on demand displacement, and avoided the waste of big water gaging, water-saving result is remarkable.

3, owing to reduce the number of mechanism, save fitment material, reduced mechanical obstacles, thereby cost, spirit used Alive, convenient, laborsaving.

4, this water valve can be replaced former water valve, utilizes raw water box thereby keep.

5, if this water valve is supporting with the new system water tank, and new water tank volume weight can reduce, thereby helps production, the transportation of water tank, reduces cost.

6, this water valve can be used for low level cistern and also can be used for high level cistern.

Above-mentioned these advantages are not comparabilities of prior art.

Claims

1, a kind of water saving leakproof water tank drain valve is the accessory on the sanitaryware.It is characterized in that push away dead man or pull rope and connect the water shutoff device, the water shutoff device is cup-shaped up and down in the small opening cover, is circular cone with outfall and cooperates, and an elastic force apparatus that the water shutoff device is resetted is arranged in the small opening cover.
