Abstract

The utility model relates to a cistern valve, belonging to the technical field of the sealing technology of water tanks for urinals. Two solid smooth and clean planes are tightly combined to achieve the purposes of sealing and leakage prevention. When liquid is contacted with the smooth and clean planes, a liquid film is formed on the solid surface, air between the two solid smooth and clean planes is extruded by the liquid film, and a vacuum state between the two contacted planes is formed, and the two planes are tightly sucked and combined. The end face of the drainage hole is made into a smooth and clean plane, the other smooth and clean plate is used as a movable plate and is covered on the smooth and clean plane, the movable plate does a rotation corresponding to the plane of the drainage hole end, taking the axle as a centre, and flushing and water sealing of water tanks for urinals are realized by the rotation of the movable plate corresponding to the plane of the drainage hole end.

Description

Cistern valve

Cistern valve belongs to the Water tank for urinal technical field of sealing technology.

The seal water structure of the existing Water tank for urinal of China all adopts a formula seal water structure, promptly all is to adopt a rubber skin plug to drop in the drain hole to reach the water shutoff purpose with this.This mode has a defective, promptly can not guarantee all the time rubber skin plug fall the position requirement accurately, such as, because the skin plug is subjected to the irregular effect of current, the skin plug position that falls is not just producing the gap, thereby makes the continuous water clock of water, as the water saving hard nut to crack, update for these years, but therefore the circle of a formula of not deviating from all the time presses for new design new construction now and solves.

The purpose of this utility model provides a kind of formula structure but adopt two bright and clean planes to be close to the Cistern valve of water shutoff of need not falling.

The utility model is based on following principle: when liquid contacts with the surface of solids, it can form one deck liquid film at the surface of solids, and liquid film supplants air between the smooth flat of two solids, make between two contact planes and to form " vacuum " state and tightly inhaled together, be difficult to if want two solid vertical to separate this moment, but two solids are easy to along planar slide each other, and the liquid film of this moment just plays lubrication.In view of the above, the utility model is made bright and clean plane as deciding plate with the drain hole end face, covers on it that another is dull and stereotyped as moving plate, on the moving plate with decide the one side that plate contacts and also make and the corresponding bright and clean plane of drain hole end face; Move sleeve-board on a vertical axle that connects firmly, and can rotate around the axis with the drain hole transverse plane; Drain hole transverse plane and moving plate all are fan-shaped, the semicircle hole of slitting is arranged on a fan-shaped limit of moving plate, when semicircle slit the hole with drain hole when crossing water just go out, when the open-minded hole of semicircle and drain hole is non-intersect and two bright and clean planes when being close to, seamless therebetween boring is so play the water shutoff purpose.

The utility model design is unique, novel structure, and water shutoff is reliable, and urban water conservation is had good prospect.

Concrete structure of the present utility model is provided by the following drawings and embodiment:

Front schematic view when Fig. 1 is the Cistern valve water shutoff;

Front schematic view when Fig. 2 is the Cistern valve draining;

Fig. 3 is the side schematic view of Fig. 1;

Fig. 4 is the moving plate schematic diagram of Cistern valve.

Cistern valve is made up of tool drain hole transverse plane 6, moving plate 1 and torsion spring 2, drain hole 5, axle 7 and limited block 11 are arranged on the drain hole transverse plane, axis hole 8, the open-minded hole 9 of semicircle, rope hole 10 are arranged on the moving plate, the shaft hole sleeve of moving plate on axle 7, make plate whole be covered with the drain hole transverse plane, torsion spring 2 is positioned at the moving plate outside and also is enclosed within on the axle 7, the torsion spring minor face is fixed on the axle, and another long limit pins moving side of plate; The drain hole transverse plane is bright and clean vertical guide, promptly plane, drain hole transverse plane 6 place respectively with the vertical axis of bleed off pipe 3, the vertical axis line parallel of gutter 4, the one side that moving plate contacts with the drain hole transverse plane also has its corresponding bright and clean plane; The drain hole transverse plane is shaped as fan-shaped, and its fan heart bisector of angle does not overlap with the line in the fan heart and the drain hole center of circle, and axle 7 is positioned at place, fan heart angle, drain hole top, and place, axle outer end has external screw thread to cooperate with nut, and limited block is positioned at a side of drain hole transverse plane; The shape of moving plate also is fan-shaped, and the open-minded hole 9 of semicircle is positioned on the fan-shaped bar straight flange, and rope hole 10 is on fan-shaped arc, and axis hole 8 is at place, moving plate fan heart angle; For guaranteeing enough Sealing Surface, fan heart angle α ', the α of drain hole transverse plane and moving plate is respectively 80～100 ° and 95～110 °; The center of axis hole 8 to semicircle slit hole 9 the center distance and axle 7 the axle center to the distance of center circle of drain hole 5 from equating; Rope hole on the moving plate is connected with tightrope by rod with handle.

Use the utility model, when not draining, moving plate entirely is covered with drain hole, because the effect of water tank internal water pressure tightly sticks together the bright and clean plane of two contacts, makes that water is seamless to be leaked; When the needs draining, move handle, the moving moving plate of rod and rope band pivots, and slits the hole when intersecting with drain hole when being threaded to semicircle, and water is just gone out from gutter, when the open-minded hole of semicircle overlaps with drain hole, the displacement maximum; Work as release handle, moving plate homing under the effect of torsion spring power, promptly the open-minded hole of semicircle breaks away from drain hole and makes board plane seal drain hole, has limited block to limit at drain hole transverse plane one end and overruns when torsion spring power makes the plate return.
