Abstract
The utility model discloses a stepless controlled water-saving valve, which comprises a button, a button seat sleeve, a swinging block, a lever, and a push-pull rod, wherein, the lower end of the button and an upper end shaft of the swinging block are movably connected; a lever fulcrum which is fixed on the button seat sleeve is deviated from vertical center lines of the button and the swinging block. The upper sides of a power arm and a resistance arm of the lever are respectively provided with an arc positioning slide way with a certain length. The utility model is installed on a cover plate of a low cistern of a water closet, when water is drained, the utility model can control water drain valves in the cistern to stop draining water freely according to the needs of users, and the aim of saving water can be realized.
Description
The utility model relates to water-saving stepless control Water-saving valve, is specially adapted to the stepless gauge tap of the draining valve in the low cistern for closet bowl.
Existing " two grades of adjustable joint joint tapses of low level cistern " (application number: 86206174; Open day: 870805), adopt eccentric wheel structure, hold handle [7] on the water tank wall during use when turning clockwise, displacement was 0.63～0.95 liter, and when being rotated counterclockwise, displacement is 0.28～0.31 liter, and the once little displacement of every usefulness can economize on water 57～62%.Also has " flush toilet Water-saving valve " (application number: 97214159.6; Open day: 981007), it set up big and small sheath, spring, positive stop block on the basis of traditional tank switch, thereby makes switch be in low, high two grades position, reaches water-saving purpose.
More than enumerating two kinds of existing Water-saving valves, is that the draining of the draining valve in the toilet seat water tank is divided into large and small two grades (or high and low second gear) control displacement after all.These Water-saving valves can't satisfy the needs of customer requirements and social technology progress.
The purpose of this utility model provides the stepless control Water-saving valve of the draining valve in a kind of low cistern for closet bowl, it is installed on the water tank cover plate, according to user's needs, any moment (being stepless control) all can be controlled the water discharge value in the water tank, reaches water-saving purpose.This stepless control Water-saving valve is simple in structure, makes easily, and materials are little, and convenient and reliable operation, life-span are long.
The purpose of this utility model is achieved in that stepless control Water-saving valve, and button, button cover for seat, spring, swinging block, lever and pull bar are arranged.The lower end and the swinging block upper shaft that it is characterized in that button link together versatilely, the key base cover is used for button is carried out spacing motion, the fulcrum of lever is fixed on key base and puts, and the fulcrum of lever to depart from button and swinging block vertical center line some, make draining valve not before the draining, the power arm of lever necessarily is on the vertical center line of button and swinging block, the power arm of lever and the spacing slideway that certain-length is arranged of an arc (or oblique) is respectively arranged above the resistance arm, the resistance arm end of lever is connected versatilely with the pull bar upper end, pull bar lower end and draining valve valve shaft are again to link together versatilely, thereby make stepless control Water-saving valve control opening or closing of draining valve in the low cistern for closet bowl, reach water-saving purpose.
Be further described below in conjunction with 1,2 pairs of stepless control Water-saving valves of accompanying drawing: accompanying drawing 1, accompanying drawing 2 are schematic diagrames of stepless control Water-saving valve structure.(1) button; (2) button cover for seat; (3) spring; (4) swinging block axle; (5) swinging block; (6) lever; (7) lever moving arm slideway; (8) lever resistance arm slideway; (9) balance pivot; (10) pull bar.This stepless control Water-saving valve, the lower end of button (1) and swinging block axle (4) link together versatilely; The fulcrum (9) of lever (6) is fixed on the button cover for seat (2), and depart from button (1) and swinging block (5) vertical center line, draining valve in the assurance toilet seat water tank not draining button (1) and swinging block (5) before is in this one side of lever moving arm slideway (7), lever moving arm slideway (7) and lever resistance arm slideway (8) are the spacing slideways that certain-length is arranged of arc (or oblique), it is characterized in that the A place on lever moving arm slideway (7) and lever resistance arm slideway (8) line of demarcation, A is the top in the fulcrum of lever (6) (9), A is the highest order of lever moving arm slideway (7) and lever resistance arm slideway (8), guarantees that swinging block (5) is to move to the two ends of resistance arm to power arm or from A from A at the lever moving arm slideway (7) and the direction of motion above the lever resistance arm (8).The resistance arm end of lever (6) and pull bar (10) upper end link together versatilely, and the draining valve in pull bar (10) lower end and the toilet seat water tank links together too versatilely.
Toilet seat water tank advances full water automatically, when the needs flushing closestool, firmly click for the first time button (1), power is subdued the power arm of lever (6) by button (1) and swinging block (5), raise at balance pivot (a 9) effect following lever (6) resistance arm, this moment, power was also upwards mentioned (opening) to the draining valve in the low cistern for closet bowl by pull bar (10), water is discharged from water tank immediately, state as Fig. 2, when firmly clicking button (1) for the first time, power is left button (1) immediately, and this moment, button (1) and swinging block (5) recovered back reset condition again under the effect of the bounce-back of spring (3), as button (1) and the swinging block (5) of Fig. 1.But lever (6), pull bar (10) and draining valve still keep the state (because for the first time during button, draining valve is upwards mentioned, and the ball float in the water tank withstands the breach of (holder) draining valve valve shaft immediately by the arm of force, and draining valve can not be fallen any more) of Fig. 2.At this moment the vertical center line of swinging block (5) be positioned at resistance arm slideway (8) on, just any moment during this period of time (promptly draining valve open that draining begins that water in the water tank has not been arranged yet or draining valve do not close automatically yet before during this period of time any moment) in, firmly click for the second time button (1), power by button (1) and swinging block (5) the resistance arm of lever (6), pull bar (10) and draining valve axial compression are gone down, at this moment, draining valve is shut (as the reset condition of Fig. 1) immediately, water stops to discharge immediately, and Here it is has realized that stepless control Water-saving valve provides possibility.
The stepless control Water-saving valve of the utility model is applied to the draining valve in all low cistern for closet bowl, makes easily, and volume is little, and is easy for installation, and use is reliable and the life-span is long.
