Abstract

The utility model discloses a flushing valve of a cistern for a closet, which comprises a first trigger mechanism and a second trigger mechanism, wherein, the first trigger mechanism and the second trigger mechanism are respectively used for triggering and opening all or a part of water in a flushing cistern to carry out flushing. One ring regulation ring is used for regulating the flushing water quantity of the first trigger mechanism, one of two keg floats is large and the other is small. The small keg float is used for regulating the flushing water quantity of the second trigger mechanism, and the large keg float is used for controlling the flushing water quantity of the first trigger mechanism. The closet of the utility model has a two-stage flushing function that the water in the cistern is used totally or partially. The utility model has the advantages of compact structure and convenient regulation.

Description

Water closet dual-flush valve

The utility model relates to a kind of water closet flushing valve.

The water tank water yield control of lavatory sanitary water is generally fixed, can not be as required, artificially adjust the water yield easily, the possessor designs the adjustable outlet valve of water supply volume to the greatest extent, but, also complicated on the structure actual owing to not matching with existing water valve, can not be combined as a whole with existing equipment well, and otherwise designed is invested too big concerning existing relevant enterprise fully.

The purpose of this utility model is that a kind of together existing radiator valve combination of design combines, and can the high dual-flush valve of regulating to water yield.

A kind of valve gear that is applicable to that the control fluid flows of the utility model design, comprise first flip flop equipment that the water that is used for triggering whole water yields of opening wc flushing cistern washes, be used for triggering second flip flop equipment that the part water yield of using wc flushing cistern is washed, be used to regulate the annulus adjusting ring of the discharging quantity of water of first flip flop equipment, small one and large one two keg floats: little keg float is used to regulate the washing water quantity of second flip flop equipment, and big keg float is used to control the washing water quantity of first flip flop equipment; Be used for the tube connector that an end connects first flip flop equipment and second flip flop equipment, the other end of tube connector connects sealing device; A cursor that is used for the big keg float of switching controls.

Described first flip flop equipment comprises that first triggers press button, division board, axle, lever.

Described second flip flop equipment comprises that second triggers press button, division board, axle, lever.

It is sealing surface that described tube connector has an end at least, has several muscle to play the guiding role, and two square holes that are connected with second flip flop equipment with first flip flop equipment are arranged.

There is aperture to be connected in the middle of the cursor, can rotates the big keg float of switching controls with circular housing body and function latch.

Described big keg float is cylindrical, and profile has the reinforcing rib of guiding, and square groove is arranged, and square groove is used for can getting out of the way cursor when big keg float floats.

Described annulus adjusting ring side arm has the hole, and two buckles are arranged.

The lever of described first flip flop equipment has bar-shaped trough with the end that tube connector connects, the lever of second flip flop equipment does not have bar-shaped trough with the end that tube connector connects, trigger the lever that first flip flop equipment can not drive second flip flop equipment, trigger the lever that second device can drive first flip flop equipment simultaneously.

The flushing valve of the utility model water closet has the dual-flush function of all using the water in the water tank with part, compares its compact conformation, easy to adjust with existing product.

Fig. 1 is in the partial cross-sectional perspective view of initial position for the utility model.Fig. 2 is the utility model flip flop equipment annexation schematic diagram.Fig. 3 is the utility model outside drawing.Fig. 4 is in the original state schematic diagram for the utility model work.Fig. 5 is in half row's view for the utility model work.Fig. 6 is full row's view for the utility model work is in.

The utility model is described in further detail below in conjunction with accompanying drawing:

Referring to Fig. 1: original state waterstop pad 16 and base 1 sealing, little keg float 6 filled with water, cursor 5, lever 12 are in minimum position; All trigger press button 9 during water, make on lever 13 (terminal be bar shaped fluting) the drive tube connector 4 and move, make on the waterstop pad 16 that is fixed on tube connector 4 ends and move, open the outfall of base 1, realize whole drainings; Axle 11 two ends are non-circular being fixed on the body 2, lever 12, lever 13 are enclosed within rotation flexibly on the axle 11, and lever 12 ends do not have bar-shaped trough, can not drive lever 12 rotations, keg float 3 is avoided cursor 5 and is floated to the extreme higher position, under keg float 3 buoyancy function, base 1 outfall is open mode always, when the water in the water tank drains, keg float 3 suffered buoyancy are less than the summation of the weight of parts such as tube connector, tube connector moves down, and waterstop pad 16 covers the outfall of base 1, finishes the function of whole waters.Full draining water supply volume can be regulated by adjusting ring 17; Rotation adjusting ring 17 is regulated the relative position of side two strip shape gobs and body side ports 2-B, and the water velocity of discharge in body 2 chambeies is changed, thereby changes the time that keg float 3 falls, and regulates whole water supply volumes.

During partial drainage, trigger press button 7, make lever 12 rotations, drive cursor 5 rotation restriction keg floats 3 come-up height, make keg float 3 inoperative, drive simultaneously on the tube connector 4 and move, make on the waterstop pad 16 that is fixed on tube connector 4 ends and move, open the outfall of base 1, realize partial drainage, when discharge level is lower than keg float 6, because have water to play the counterweight effect in the keg float 6, under the effect of gravity, tube connector 4 moves down, waterstop pad 16 exposes outside body edges 2-A line, water impact waterstop pad 16 rapid sinking closed base 1 outfall; Finish the partial drainage function.The partial drainage amount can be regulated by the relative altitude that moves little keg float 6, and on tooth bar 8, tooth bar 8 is fixed together with tube connector 4 and transmits the gravity of little keg float keg float 6 by the profile of tooth engages fixed.Two press buttons are equipped with spring 18 between two press buttons and the division board 10 and make the press button return by being a division board 10 separately mutually noninterferes.
