Abstract

There is described a valve arrangement which in one form is an inlet valve (60) or in another form is a dual flush valve (2). The valves may be used in a variety of situations but find particular application in a cistern for providing water to flush a toilet bowl or similar. The valve arrangement (2) comprises a flushing tube (100) or a pair of flushing tubes (14, 18) which can move axially. One end of the tubes (100, 18) is sealed to an outlet (9). The tubes are provided with rings or collars (16, 22) which co-operatively engage with locking edges (48, 50) of floats (40, 44) to control movement of the tubes (100, 14, 18). The floats (40, 44) are mounted off-centre or in a position spaced apart from their respective centres of gravity so that they are free to move under the effects of gravity and the effects of lift provided by buoyancy of the floats. In operation the sequential effects of gravity and buoyancy cause the floats to hold the tubes in position and then release the tubes thereby allowing selective flushing positions.

Description

Valve gear and have the water tank of this valve gear

Technical field

The present invention relates to valve, be particularly related on the one hand the valve in the fluid that immersion flowed by its control, be particularly related to control on the other hand and flow through the valve that the fluid of valve flows.In more detail, the present invention relates to control the particularly valve that flows of water of liquid.Say in further detail, the present invention relates to be applicable to the valve in the water tank,, for example be used to guide the water intaking valve that water enters water tank with flush toilet and similar device, and flushing valve, particularly dual flush valve, be arranged in of the discharging of water tank control water from water tank.The present invention is used in water intaking valve and/or the dual flush valve that has such as two kinds of operational modes in the water tank of office building, hotel, household or similar building particularly.

Background technology

Though the present invention will be described with reference to the water tank with a dual flush valve and/or water intaking valve particularly, but should understand that the present invention is not limited to such structure and application, and scope of the present invention is more broader than specifically described content, also comprises other structure and the application of valve.

A problem of existing tank intake valve of water is the operation gradually between two extreme positions of this type of valve.Therefore, be imported into the changes in flow rate of the water of water tank after having dashed flush toilet, and cause disagreeable noise, for example produce the sound that " neighing " sound or water enter water tank.This noise limits flowing of water gradually by water intaking valve and slowly reaches its complete make position and caused.This disagreeable noise can continue a very long time after water tank overflows under extreme case, and the troublesome irritability may wake the sleeper in contiguous bedroom or the building, many rooms up under the situation when particularly filling with water tank at night.

Another problem relevant with the valve that uses in the current water tank is particularly bulky, the complex structure of its traveling mechanism of this type of valve, causes valve to occupy big quantity space in water tank.This also will require the water tank size bigger.Large-sized water tank has reduced to have in the building space of water tank existence, and has reduced the flexibility of designer when design water tank and room of living in thereof.

The another problem relevant with the single flush valve is that it is wasted water, and reduces the required water yield of once flushing because they are provided with, even when not needing so many water.

The particularly two relevant problems of wc flushing cistern valve of another and existing radiator valve are its operations and manufacture complexity that a large amount of interactional discrete components are arranged.Not only these elements involve great expense, and element will wear and tear after a period of time, the neighbouring element that particularly contacts with each other, as pivot joint, pin or like, with and/or the place of seal is set.Wearing and tearing in the operation of valve or driving mechanism and/or the seal will cause interelement loose or excesssive gap, thereby cause leaking or other problem, the sealing of for example going into and exporting is poor, has therefore reduced the efficient and the validity of water tank and has needed too frequent reparation.In many cases, through after the extreme wearing and tearing, valve drips continuously more or less or water is spilt from water tank, particularly bleed in the flush toilet, and be accompanied by disagreeable noise, comprising valve part open and make position between vibration, bothersome " neighing " noise when water tank is filled in water continuously.In addition, the continuity leakage of water tank can cause flush toilet ugly stain to occur.

Summary of the invention

Therefore, need the valve gear that is applicable in the water tank is set, as flushing valve, particularly two wc flushing cistern valves, it should be the operational efficiency height, the element decreased number, occupy minimum space, operation is noiseless or almost noiseless, can move effectively and seldom or not need keep in repair, mounting cost is cheap.More than require equally at water intaking valve, especially water intaking valve should be able to voicelessly move fast and not produce between closure and the full open position fully or cause water hammer or disagreeable noise.

According to a first aspect of the invention, be provided with a valve gear, this valve gear comprises at least one movable valve member, and described valve member can move between unlatching and make position; Reach one and drive the actuator that valve member moves between unlatching and make position, described actuator is installed by this way: its action is in one direction driven by first power and action on second direction is driven by second power, then described first power under a kind of situation of valve gear operation play a major role and under second situation that valve gear moves described second power play a major role.

Specifically, valve gear of the present invention is a water intaking valve or a flushing valve, especially a dual flush valve.Especially, valve is arranged in a water tank.

Especially, the first movable valve member is a cylindrical tube.In detail, this pipe both ends open.Say that in more detail valve member is two open-ended cylindrical tube of mutual conllinear.More particularly, the sealing of the respective openings end of two pipes is interconnected.

Especially, movable valve member or two or more movable valve members are done axially-movable in water tank.

Especially, for its enable possition of flushing valve water is flowed out with draining from outlet.More specifically, two enable possitions are arranged, wherein first enable possition is half flush position that outlet communicates with one of cylindrical tube or cylindrical tube corresponding to the direct flushing fully and second enable possition of opening of outlet, produces half flushing thus.More specifically, when having only when pipe, described pipe is set to have and two two diverse locations that different exit positions are corresponding, and these two positions are depended on and washed fully or half flushing state.Single pipe can be positioned at two differing heights, is positioned at 30cm place above the outlet and is partly washing the enable possition and be positioned at 15cm place above the outlet washing the enable possition fully.

Especially, move the water to flow into water tank for its enable possition of water intaking valve.

Especially, the actuator that drives the valve member operation is one to have float or other part of an annular seal space.Especially, float is provided with a braking limit.More specifically, float is provided with the pivoting action amount of a stop mechanism with limiting valve run duration float.More specifically, actuator is one, two, three or more a plurality of float.Say that especially float is made by plastics or materials similar.

Especially, the vertical section of float is triangular in shape and the cross section takes the shape of the letter U.Especially, float connects pivotally or is installed in the valve gear.

Especially, eccentric connection of actuator or installation or coupled position not with the corresponding position of center of gravity, therefore can pivot around interface.More specifically, float pivots under action of gravity and can independently pivot in buoyancy.

Especially, cause that first power that actuator moves is gravity.More specifically, second power is the lift by the buoyancy generation of float.

Especially, valve gear of the present invention is applicable in the water tank.When the water tank emptying, gravity plays a major role and makes float be in basic vertical direction or more vertical direction.More particularly, when the water tank fills with water, being played a major role by the float power that buoyancy causes in water makes float be in the vertical bank direction.More particularly, the operation of valve is caused that by the comprehensive function of gravity and float described more in particular each power makes float go back to a position to prepare next step operation according to priority.

Especially, water tank is provided with a dual flush valve and a water intaking valve simultaneously, and two valves cooperatively interact to operate water tank in application.

The specific embodiment

Fig. 1 shows a kind of form of irrigator valve apparatus to Fig. 4, and this device is a dual flush valve, with label 2 expressions.Dual flush valve is characterised in that it has and two kinds of corresponding two outlets of backwashing manner, and wherein a kind of mode is to have only low amounts of water to enter half flushing of flush toilet, another mode be almost in the water tank all water all enter the flushing fully of flush toilet.Flushing valve 2 comprises that one firmly is installed on the main frame 4 of water tank inside by suitable mechanism (not shown).Framework 4 comprises that one is firmly fixed on water tank pedestal or the soffit 7, is used to make the bottom level carriage 6 of framework 4 stationary positioned.Carriage 6 is provided with a circular hole to admit the bottom of a cleaning hose (hereinafter will describe in detail), and this cleaning hose is located immediately at the top of water tank outlet 9 as a screwed pipe and nut apparatus 11 by a suitable retention mechanism.Framework 4 comprise also that the vertical extension of opening a pair of horizontal interval 8 and is positioned at or towards vertical member 8 tops to connect the upper support frame 10 of vertical member 8.One cover plate 13 is arranged at frame 10 tops between the vertical member 8.Upper support frame 10 also is provided with a circular hole to admit the upper end of cleaning hose on.One hollow circuit cylinder tubular first movable valve member 14 both ends opens and as last cleaning hose, the circular hole of its bearing support 10 of packing into.Last pipe 14 is freely moving axially in frame 10 between make position and a unlatching flush position fully.Last pipe 14 be provided with one be positioned at the pipe two ends in the middle of, around encircling or enclose 16 on its circumference.Ring 16 can have any suitable profile and be made by any suitable material.Last pipe 14 and pipe 18 interactions down.The lower end of pipe 14 is shown in broken lines to show the internal details of the sealing device 17 between pipe 14 lower ends and following pipe 18 upper ends among Fig. 1.Sealing device 17 comprises the seal 19 of a v-seal spare or tapered edges, the sealing part is around being arranged at down pipe 18 upper limb, and the lower edge of going up pipe 14 like this can be installed in the seal so that two seals of tube engage and prevent in the water inflow pipe during with the full open position use closed fully.

Following pipe 18 as the second movable valve member is set to join with last pipe 14 head and the tail centerings.Encircle or enclose 22 once around being arranged at down pipe 18 two ends intermediary outside.The lower end of pipe 18 is provided with a sealing device 20.Sealing device 20 is installed on again in the carriage 6 and as managing 18 tops that directly are installed on water tank outlet 9 down.Sealing device 20 is provided with the seal 21 of a v-seal spare or conical wall, and the lower edge that pipe 18 down is installed in the sealing part is with sealing radiator, and water outwards flows out when preventing complete make position.

Should note encircling 22 to the distance of managing 18 lower ends down under upward the distance of ring 16 supreme pipes 14 lower ends is different from.Under manage 18 can be in full open position and move axially between the make position fully.

One center round bar 26 is arranged in the upper and lower pipe 14 and 18 that centering connects along axis, and stretches out ends of tubes.Round bar 26 is held in place by passing to lay respectively at or reach the centre bore 27,29 of managing the width of cloth bar 28,30 of 18 lower ends down towards last pipe 14 upper ends.Width of cloth bar 28 and 30 can form with pipe 14 and 18 integral body, also may be separately formed and is assembled on the pipe.One end of activation lever 32 links to each other with center round bar 26 and the other end links to each other with depression bar 33, with the motion that causes the center round bar and cause valve to be in the flushing fully of full open position.The other end of depression bar 33 links to each other with full flush button or similar device (not shown) on being arranged at water tank.One end of activation lever 36 links to each other with width of cloth bar 28 tops and the other end links to each other with depression bar 37, is separated from each other and half flushing of the semi-open position that causes to cause the motion of going up pipe 14 and to cause valve to be in by pipe 14 and 18.The other end of depression bar 37 be arranged at water tank on the half push button (not shown) easily or the similar device at the place of keeping to the side link to each other.

Float 40 is pivotally connected on framework 4 by pivot pin 42 or like and is positioned at or towards the upper end of vertical member 8 on one.Once float 44 is pivotally connected on framework 4 by pivot pin 46 or like and is positioned at middle position near the lower end, part 8 two ends.Upper and lower float 40,44 can freely pivot between two different run locations, and the complete make position when one of them position is the water tank fills with water and another position are locking pipes 14 or manage 18 enable possition.

Float 40,44 sealing is forming an enclosed cavity, and eccentric the pivot, so the pivot center does not overlap with center of gravity or float center.In this manner, when the water tank emptying under the effect at gravity float 40,44 can freely pivot to reach a more vertical or vertical substantially position; And float 40,44 can freely pivot to reach an obliquity during when the water tank fills with water or at a kind of flush position.

Produce buoyancy owing to charging into air in the float in the application, float 40,44 normal positions are the position that corresponding piece 8 tilts when the water tank fills with water, and are extremely shown in Figure 4 as Fig. 2.In service, float 40,44 moves to the less obliquity of a gradient, and more vertical position for example shown in Figure 1 is so that valve member 14,18 returns the make position of being determined by the Cistern flushing mode.Float 40 be provided with one along its in longitudinal edge, over against the locking edge 48 of last pipe 14, go up ring 16 in use to cooperate to be connected, and a shoulder 49 along a side diagonally extending, limit the motion of float 40 with the edge that is connected part 8.Float 44 be provided with one along its in longitudinal edge, over against the similar locking edge 50 of managing 18 down, be connected ring 22 down in use to cooperate, and a shoulder 51 along a routine limit or two opposite side diagonally extendings, limit float 44 pivoting action in the counterclockwise direction with the edge that is connected part 8.

To begin to describe the operation of valve gear of the present invention from half flushing operation now.In service partly washing of flushing valve 2 of the present invention, the water tank fills with water is to the water level shown in Fig. 2-4, and this water level is near the top of last pipe 14.Should be understood that water level be lower than open-topped inlet tube 14 top edge horizon and near the horizon of the bracket 10 of framework 4.When the water tank fills with water, float 40,44 is the gradient obliquity shown in Fig. 2-4, and float 40 and 44 this

moment driving angle

48 and 50 separately contacts the sidewall of two inlet tubes 14,18 respectively, particularly as shown in Figure 3.In this case, the position of valve 2 is complete make position among Fig. 3, be go up pipe 14 and with following pipes 18 sealings of outlet 9 sealings, held the water in the water tank like this and anti-sealing flows into the flush toilet from water tank.This is the normal position that water tank is prepared running status.Water enters water tank by an independent water intaking valve, and its details will be described below.

When wishing that water tank partly washes, half push button on the promotion water tank upgrades pipe 14 to drive depression bar 37 and lever 36, makes being tightly connected of pipe 14 disengagings and pipe 18, and breaks away from seal 17.Because pipe 18 and seal 20 location that is tightly connected, separate with the upper end of managing 18 so manage 14 lower end.Through this operation, the pipe 14 be raised enough highly so that encircle 16 by float 40 along clockwise direction the utmost point pivot slightly and return the locking edge 48 that its original position is crossed float 40, so limit 48 keeps withstanding and from following Supporting ring 16 with locking and pipe 18 pipes that separate 14, as shown in Figure 2.In this position, water from Fig. 2 between two pipes shown in the arrow A backlash freedom flow through.Be noted that pipe 18 is undisturbed in this operation, and maintenance and water tank export 9 be tightly connected.

When water level is reduced to float below 40, when also promptly reducing to approximately with pipe 18 top corresponding horizontal, the lift of the float 40 that is produced by buoyancy no longer works.Because float 40 is eccentric pivots, its under action of gravity by counterclockwise pivoting, so limit 48 is removed and ring 16 is discharged from the locking on limit 48, to reach it in the position shown in Fig. 1 along himself axle.It should be noted that limit 49 and contacting of part 8 can prevent that float 40 pivot amplitudes are excessive.Because ring 16 is released, pipe 14 falls under action of gravity, reseals to be connected and to form with seal 19 with pipe 18 to seal.Water enters water tank by a suitable water intaking valve (hereinafter will describe in detail) then, so the water level in the water tank rises to former level.The water level that raises offers float 40 lift, thereby float 40 is pivoted by the clockwise direction shown in Fig. 2 arrow B and reaches a gradient obliquity, for half flushing next time or fully flushing prepare.Should note when the water tank emptying float 40 be vertical and during the water tank fills with water float 40 are vertical banks.

Complete backwashing manner in flushing valve 2 of the present invention is in service, and its water level as previously mentioned during the water tank fills with water.The full flush button that promotes water tank is so that depression bar 33 motions, then depression bar 33 activation lever 32 are to promote by width of cloth bar 30 and hole 29 and the following pipe 18 center round bars 26 that link to each other, make being tightly connected of pipe 18 disengagings and seal 20 so break away from seal 21 by riser 18, therefore expose a gap, water is able to flow inlet and outlet 9 from here, shown in Fig. 4 arrow C.Pipe 18 is raised enough highly so that encircle 22 limits 50 of crossing float 44, cause limit 50 to keep withstanding and from encircling the pipe 18 that 22 lower supports are in full open position, and make valve remain on the water level of this position in water tank always and be reduced to below the lower limb of float 44, when promptly exporting 9 level approximately till.Should note being raised equally owing to pipe 18 is raised so manages 14, consequently the complete backwashing manner run duration that is sealed in of managing between 14 and 18 remains, and unique outlet that water flows out is at water tank bottom.Should note also pivoting at this run duration float 40.But this pivot is to the operation did not influence of equipment, because at the float in service 40 of this mode contact ring 16 not, this is because ring 22 is different to the distance of float 40 with ring 16 to the distance of float 44.Say further, should note encircling 16,22 position and should make pipe 14,18 keep one of two positions: or flush position fully, or half flush position.The locking edge of two floats can not lock two pipes simultaneously.

Since the mounting means of floating part 44 with float on 40 similar, float 44 by pivoting counterclockwise and discharging ring 22, makes pipe 18 be fallen by action of gravity under action of gravity, sealing exports 9 again.Water intaking valve operation moves the water to flow into water tank then, so water level is crossed float 40 after crossing float 44 earlier, each float is successively by clockwise pivot and get back to original position, and its limit 50 and limit 48 lean against pipe 18 respectively and manage on 14, but its position is respectively on

ring

16 and 22 tops.

Describe another form of valve gear of the present invention now, promptly be positioned at a water intaking valve 60 of water tank (not shown) inside.The base of water tank or soffit 62 are provided with to be installed a vertical tube 64 and uses conventional seals gland sealed hole.Vertical tube 64 links to each other with common pressurized water source and from its inside water is infeeded water tank.Water supply to water tank is controlled by the operation of water intaking valve 60.

Valve 60 is positioned at the top of the vertical tube 64 on water inlet 66 and the gutter 68, and gutter 68 is provided with a nozzle (not shown) or the energy of similar jet pipe to disperse to intake, and makes the valve silent running.Valve 60 comprises a float 70, and this float takes the shape of the letter U on the horizontal section at rectangular triangle on the vertical cross-section, as Figure 6 and Figure 7.Float 70 is set to vertical tube 64 and passes " U " v notch v inside, and this float is connected with vertical tube pivotly, and its leg-of-mutton one side is basic vertically and the another side basic horizontal, and it is orthogonal that described limit is set to, and the 3rd hypotenuse tilts on other both sides relatively.But should be noted that the accurate shape that can change float.In the normal position, i.e. operation ready position during the water tank fills with water, the relative vertical tube of float tilts, and its position is to pivot in the counterclockwise direction from position shown in Figure 5.Float 70 is provided with a support 72, and this support is arranged in its upper edge of using and towards the summit of horizontal sides and hypotenuse.One activation lever 74 or lever 76 or depression bar or similarly an end of power or motion transmitting device or connecting rod link to each other with support and other end setting or link to each other with a cam 78.This connection and cam gear can make the upper end of cam 78 extruding plungers 80, and plunger 80 is positioned at the suitable housing 82 of a formation guiding valve.Should notice that two ends respectively establish the single lever of a roller and can replace lever 74,76 and cam 78.In this embodiment, one of roller directly acts on the plunger 80 of guiding valve.

Two round section joint rings 84,86 are arranged between plunger 80 and the housing 82 to seal this housing and to prevent that sealing overflows from this housing.The lower end that one flange 88 is arranged at plunger 80 in the application with close or open water inlet 66 and adjust water from vertical tube 64 through water inlet 66 flowing to gutter 68.Housing 82 is provided with one and regulates the stroke of nut 90 with pilot plunger 80, so that float 70 has a gap so that water flows into water tank between plunger 80 tops and the cam 78 when being in vertical position, is tightly connected and make flange 88 and enter the mouth 66 when valve is in the close position.An improvement of guiding valve is that valve is provided with a mechanical caging, makes improper unlatching of valve or leakage to avoid excessive hydraulic pressure.

In service in this form of water intaking valve, when the water tank emptying, float 70 is in vertical or basic upright position as shown in Figure 5, so that cam 78 separates with plunger 80, flange 88 66 discharges from entering the mouth, and makes water 66 flow into water tanks to gutter 68 from vertical tube 64 through entering the mouth.Because the water level in the water tank is increased to around the float 70, the buoyancy that acts on float 70 overcomes the gravity that acts on it makes float 70 by rotation counterclockwise shown in the arrow E among Fig. 5.When water level increased, moved from left to right buoyancy or center of pressure, as shown in Figure 5.Its position is lower than fulcrum immediately, makes float rotation in the counterclockwise direction under the power effect that increases.The motion of float 70 raises support 72 and lever 74,76 together, causes lever 76 to pivot so that cam 78 contacts with plunger 80 around axle 77.When cam 78 was further rotated, plunger 80 was pressed in the housing 82, so the water that flange 88 joins and flows into water tank to cut off with inlet 66 end under this effect.Because in the time of float 70 pivoting action, inlet 66 almost is to close simultaneously, thereby eliminated the noise of " neighing " when valve cuts out gradually in the water tank of prior art.

In one embodiment, roller is used to eliminate any undesired friction.

Fig. 8 illustrates the improved form of dual flush valve among Fig. 1 to Fig. 4, improve valve except replace with single pipe 100 going up pipe 14 with manage down 18 with Fig. 1 to Fig. 4 in valve identical.Correspondingly, adopt identical label with the corresponding feature of Fig. 1 to Fig. 4 among Fig. 8.In addition, because pipe 100 is can therefore not have sealing device 17 or seal 19 from carriage 6 along its axially-movable to the single pipe of carriage 10 extensions and application.Pipe 100 the method for operation is identical with pipe 14 and 18, and pipe 100 can be raised a bit of distance, as upgrading 15mm from seal 20 reaching half flush position, or has been raised one than distance greatly, and for example about 30mm is to reach a complete flush position.

Improve the in service of valve gear at this, the water tank fills with water is to water level shown in Figure 8.When needs partly wash, handle depression bar 37 and lever 36 and upgrade pipe 100, ring 16 is locked by limit 48.In this position, the lower end of pipe 100 is from outlet 9 about 15mm, so that water flows out from outlet with low flow velocity before water level is lower than float 40, after this float 40 makes limit 48 from encircling 16 releases and pipe 100 being fallen under action of gravity along pivoting counterclockwise, again be connected with seal 20, so valve is taked a complete make position after half flushing.Be noted that since ring 22 to the limit 50 distance relatively ring 16 48 distance is bigger to the limit, limit 50 is locking ring 22 but encircle 22 and be positioned under the limit 50 not, therefore float 44 is inoperative in half backwashing manner.After more than half flushings, water intaking valve 50 operations are to refill water tank, and float 40 reaches " preparation " position as shown in Figure 8.

When needs washed fully, depression bar 33 and lever 32 actions made locking edge 50 withstand ring 22 to upgrade 100 1 bigger distances of pipe, are locked in outlet about 30mm place, 9 tops and will manage 100.Corresponding to the position of flushing fully, water flows out outlet 9 with bigger speed.Should be noted that complete flush position ring 16 be positioned at locking edge 48 above, so float 40 is inoperative in this position.When the water tank middle water level was brought down below float 40, float 40 pivoted counterclockwise in the action of gravity lower edge, but because ring 16 is positioned at 48 tops, limit, and the motion of float 40 does not exert an influence, pipe 100 still is in the enable possition of flushing fully of being withstood ring 22 by limit 50.Water level continue to reduce up to being lower than float 44, so float 44 discharges ring 22 along pivoting counterclockwise, and pipe 100 is fallen under gravity into form again in the seal 20 and is tightly connected.Water intaking valve 60 operations are to fill with water tank then, and when water level covered float 40 and 44 respectively, two floats pivoted to reach " preparation " position under buoyancy respectively successively clockwise.

The advantage of water intaking valve of the present invention is that its structure is unique, perhaps is in full open position or is in complete make position, and nothing postpones progressive motion and is snap action between two extreme positions.This water intaking valve does not have intermediate stopper or delay.This advantage is realized by designed waterpower float, this float will remain on full open position, float as shown in Figure 5 vertically downward at this moment, reach a precalculated position up to the increase of water tank middle water level, this moment, valve was noiseless, free and move to complete make position like a dream, cut off the water that flows into water tank thus.In addition, even valve rapid movement between unlatching and make position does not have water hammer yet and takes place.

Float drives a lever that as above designs, and utilizes the advantage of composite structure to produce a considerable active force at the opening part of inlet 66.

When valve was in the enable possition, water entered via gutter and from then on Guan Yiyi predetermined angular and constant rate of speed are ejected on the water tank wall.The jet pipe of designed injection water makes into that the water energy is absorbed by the water tank sidewall, and then causes noiselessness.

Because it is constant to enter the water flow velocity of water tank between the whole flood period, therefore might eliminate angry " neighing " noise that makes us that in traditional water tank that is provided with progressive shut off valve, exists.

Another advantage of the present invention is that " water chestnut " shape horizontal section of float can make it around vertical vertical tube, has therefore reduced the valve element and has operated required space.

Should be understood that water intaking valve of the present invention and dual flush valve can be arranged in the same water tank, so that two valves combined running mutually.

Dual flush valve of the present invention particularly among Fig. 8 the another advantage of valve be to reduce the quantity of element and only needed a seal, thereby reduced cost and improved the reliability of valve gear.

Described device is proposed by explanation, and can carry out multinomial improvement under the prerequisite that does not break away from spirit of the present invention and scope, comprises the compound of disclosed each innovative characteristics and innovative characteristics.
