Description
Technical field
The present invention relates to a kind of drain valve assemblies as described in the preamble for flushing cisterns according to claim 1.
Background technique
General drain valve assembly is suitable for flushing cisterns, is especially used for toilet cistern.This flushing cisterns usually has controlled
Water unit, flushing cisterns is filled into scheduled packed height by the water unit.For this purpose, for example, providing a kind of floating
The supply valve of control opens or closes supply according to packed height.It is opened in addition, this flushing cisterns has usually on the downside of it
Mouthful, drain valve is arranged in said opening.Obstruction and release by drain valve assembly control opening.When opening is released, punching
Water in tank-washer is due to gravity it is anticipated that outflow opening.Self-evident, water is herein only generally as the Usual examples of fluid
It is mentioned.
General drain valve assembly usually has clack box, which is embedded in flush box by sealing device, such as O-ring
Opening is for the intended purpose.Clack box itself has discharge outlet, and when clack box is sealingly fixed in opening, which is arranged
To be aligned with the opening of flushing cisterns.In addition, general valve gear has the valve being slidably disposed along vertical direction relative to clack box
Body.For this purpose, guide device appropriate is arranged, valve body is by the supported on flushing cisterns and/or on clack box.Row
Water valve device usually has the valve chest being placed in clack box, and valve body is guided guided along vertical to ensure in the valve chest
The displaceability in direction.This valve chest is typically designed to the form of hollow, and valve body usually has float portion, the float portion
It is guided and can be slided along cylinder axis in valve chest in a manner of formed punch, wherein cylinder axis orientation is and vertical direction
In parallel.
In general drain valve assembly, valve body has pipeline, which extends from the overflow port on top along vertical direction
It interconnects to the outlet of lower part, and by two openings to carry out fluid conveying.In addition, the lower end of valve body is designed as valve
Base has the sealing element corresponding to clack box.In this way, valve body usually designs as tubes or has tubular portion, wherein pipeline
It is fixed by pipe or tubular portion.Sealing element on valve base is corresponding with clack box, so that in the closed position of drain valve assembly, sealing
It part sealing and water-tight is supported on clack box, particularly on the valve seat of clack box.In this way, sealing element corresponds to each other with clack box, make
It obtains and avoids water because sealing element is sealingly born against on clack box around discharge outlet in closed position and escaped into from flushing cisterns
In discharge outlet.In most cases, valve body has circular and closed conduct periphery wall portion, wherein sealing element seals twelve Earthly Branches
It holds in wall portion, and in closed position, wall portion is hermetically connect with clack box.General drain valve assembly is most of with such as lower section
Formula design: in order to open drain valve assembly from the closed position of drain valve assembly, making valve body relative to clack box upward displacement, thus
Through-flow gap is formed between sealing element and the part around discharge outlet of clack box, by the through-flow gap, water energy enough passes through
Discharge outlet is discharged from flush box.In this way, pipeline realizes the function of overflow pipe.It is connected to each other because pipeline has to carry out
The overflow port at its upper end of fluid conveying and the outlet at its lower end, so can ensure the water supply in flushing cisterns
In the case where dysfunction, when reaching the maximum packed height of flushing cisterns, due to the cooperation of flushing cisterns and drain valve assembly, water
Enter in overflow port at the upper end of the pipeline of valve body and flowed out by outlet at lower end, while drain valve assembly is in it
Closed position.Therefore flushing cisterns and drain valve assembly are usually arranged with respect to one another as follows: when drain valve assembly is in
When closed position, the outlet of drain valve assembly, which will be exported, to be connect with the discharge outlet of clack box to carry out fluid conveying, discharge outlet itself
It is aligned with the associated openings of flushing cisterns.
In general drain valve assembly, valve base has the wall extended below sealing element.At this point it is noted that
It is that reference should be made to vertical directions in the present specification to understand term " in bottom ", " at top ", " lower section " and " top ".From
And " in bottom " and " at top " indicates opposite direction along vertical direction.The wall forms outlet at its vertical lower end, from
And limit the lower end of the pipeline of valve body.To which the periphery of pipeline is surrounded in lower end by wall.In this way, wall extend incessantly with
It is sealed on a vertical development length since the lower end of wall.In this way, wall is substantially only with extension structure along the vertical direction
Part extends, and is designed to the form of the circular cone of the continuous circular shape cross section with downward narrow contracting, and the axis of circular cone is along vertical side
To extension.On the continual vertical development length of wall, wall does not have recess portion, channel or feed through part.The wall is ensured from punching
Tank-washer escapes into the conducting of the water in outlet.When drain valve assembly is in the closed position, at least vertical portion of wall is usual
It is arranged in discharge outlet, is thus located at below the upper limb of the discharge outlet formed by clack box.The upper limb usually can for example pass through valve
The valve seat of case is formed, and the seal support of valve body is on the valve seat to seal outlet.In addition, the clack box of general drain valve assembly
Usually there is the throttle valve for the periphery for surrounding and closing exhaust openings, which is also formed as from water flush box
Water is guided when evolution.
In general drain valve assembly, wall and/or throttle valve are usually activated with the low noise as far as possible of flush toilets is made
Target matches, wherein must ensure that overflow is protected simultaneously, this usually passes through the pipe for providing and having sufficiently large effective cross section
Road is realized.In this way, main focus on the one hand in the fact that: when drain valve assembly reaches its close stance from open position
When setting, the valve body with sealing element will not be impinged upon tempestuously on clack box.On the other hand, principal focal point is in flushing operation knot
Shu Shi is avoided generating and is sobbed sound that is, shortly before drain valve assembly is closed.Sob sound is caused by following reason.With general row
During the normal operating of the flushing cisterns of water valve device, when drain valve assembly is in its closed position, flushing cisterns fill out be filled with water to it is pre-
Fixed packed height.In this state, i.e., when drain valve assembly is in its closed position, pipeline not by water fill but only by
Air filling.When starting flushing, the drain valve assembly of the closed position initial in its is opened, valve body upward displacement, thus
Above-mentioned through-flow gap is formed between sealing element and discharge outlet.Water flows into outlet by the passage gaps.Due between circulation
Gap has sizable cross section compared to flushing cisterns, therefore reaches sizable water velocity at the height of passage gaps.It is special
Not, the design of this usually cone for being attributed to wall and/or throttle valve, it is further by the flow velocity at the design outlet
Increase.Water enters the passage gaps from each side, enters center from each side, so that the water for initially entering pipeline rises, so that pipeline
Partly, it is filled in a part of its vertical scale by water.These water then pass through outlet and are discharged to outside pipeline again, make
Valve body from its initial maximum open position is displaced to closed position, so that passage gaps reduce and less water is from flushing cisterns
Outflow.In this way, on the one hand there are the various flow velocitys of water by exporting and on the other hand by passage gaps.In flushing operation
Period due to different flow velocitys and due to the different height of the water column in pipeline, has issued sizable noise, i.e. institute
" sobbing sound " of meaning.
Have taken up different measures in the prior art to cope with and this sob sound.For example, in 1 854926B1 of EP,
It is proposed is embedded in additional sleeve-like part in the wall of valve base and sleeve-like part is protruded above in the lower end of wall, to prevent a side
The shear layer that face generates between the water flow by through-flow gap from the water flow that outlet is flowed out and on the other hand, and prevent
Eddy flow and relevant noise emission.In addition, for example proposed in 2 765 249A1 of EP in wall with sealing element phase
At least one through portion is set adjacently, is reached to avoid the air column in pipeline so that valve body is in the flushing water generation by flowing out
The length of intrinsic frequency is obtained in the frequency range of frequency to avoid sizable noise is issued.However, describing in the prior art
Measure only deficiently be suitable at the end of flushing operation, i.e. before drain valve assembly arrives again at its closed position not
It prevents from sobbing sound as much as possible long.Also, it has proven that some measures that the prior art is taken be it is expensive, especially in valve
Additional component is set on base.
Summary of the invention
The object of the present invention is to provide a kind of drain valve assembly for flushing cisterns, which can save as far as possible
About implement at local and at the same time can prevent from as much as possible making a noise during flushing operation.
The present invention proposes a kind of solution of the drain valve assembly of feature with claim 1 as the purpose of the invention
Certainly scheme.
According to the present invention, wall forms the through-flow channel for horizontal liquid stream with horizontal scale and vertical scale.
Therefore these through-flow channels are placed in below sealing element.Through-flow channel for example can be by being implemented as follows: through portion is set in wall,
Or the vertical irregular scale around vertical direction alternatively is provided for the lower end of wall, it is formed and is exported using the wall.It is in office
In the case of what, through-flow channel is all formed in such a way that horizontal liquid stream can pass through through-flow channel.To which the horizontal liquid stream can
It is flowed between two be horizontally spaced out the vertical portion of wall by the through-flow channel being set between the vertical portion.
"horizontal" indicates the direction vertical with vertical direction.In this way, being typically considered as, the draining according to the present invention for flushing cisterns
Valve gear is purposefully installed together with flushing cisterns, so that substantially vertically generation acts on the gravity acted on the earth.
Therefore, drain valve assembly according to the present invention is purposefully mounted so as to during flushing operation together with flushing cisterns, water tool
It is flowed out from discharge outlet with having apparent vertical component.
Further it is proposed that blockage element, the resistance is arranged in order to reduce the horizontal effective cross section of the pipeline in wall
Plug member has a horizontal-extending blocking section, which has a confining surface, the confining surface and wall it is most downward
It is vertically spaced to stretch end.Wall most descends elongated end to refer to the rotation angle around vertical direction furthermost extended downwardly in wall of wall
Lower end at degree.There is the wall of the lower end extended in the horizontal plane for design, in this case, wall most descends elongated end by wall
The entire lower end being located at identical absolute altitude for any rotation angle around vertical direction in this case is formed.Blockage element
In the horizontal scale of wall and there is horizontal-extending obstruction section, which has the vertical scale positioned at wall
Interior confining surface.Therefore, the obstruction section and wall most descend elongated end to be spaced apart.It is particularly preferred that obstruction section is at least
10mm2, particularly at least 50mm2, particularly in 50mm2With 100mm2Between.
The interaction of the feature of drain valve assembly according to the present invention through the invention realizes the purpose of the present invention.Hair
Bright people it has been found that by ensure water flushing operation it is quite a wide range of in be completely exhausted out in pipeline and not
Pipeline and be simultaneously from the water of flushing cisterns and be still discharged with significant flow velocity by discharge outlet, Lai Shixian is at the end of flushing operation
It sufficiently reduces and sobs sound.The understanding of inventor is that it is main by the fact that causing to sob sound based on following idea: when in pipeline no longer
There are when water, the air from pipeline is taken away by the water flowed out by discharge outlet.The design of drain valve assembly according to the present invention
On the one hand provide following effect: when wall is when most descending elongated end below the top edge of discharge outlet, water energy is enough horizontally
Through-flow channel is flowed through, and is therefore entered in pipeline.To, when valve body at the end of flushing operation from valve body in drain valve
When the position of device closed position is not far, enough water still can flow through through-flow channel and from this vertically in the duct on
It rises, or generates the accumulation of water at least in the region of outlet, this hinders the water of pipeline directly to flow out from outlet.Blockage element
Horizontal-extending obstruction section with confining surface ensures level of the pipeline in the vertical height of blockage element effectively simultaneously
The reduction of cross section, once then water will be slowed down by the outflow of outlet so that water is by obstruction section, this is at least grasped in flushing
Work occurs significantly when starting.In addition, obstruction section and wall most descend elongated end is vertically spaced have the advantages that valve body exists
By substantially maintaining open position underneath towards discharge outlet flowing water in obstruction section when flushing operation starts, to have
Effect valve body is avoided after being displaced straight up from its closed position immediately back down to its closed position.Particularly advantageously
Make to block the top that section is arranged in all through-flow channels, so that the effect further strengthens.Due to row according to the present invention
The design of water valve device thereby ensures that and scans out minimal amount of air from pipeline by discharge outlet, because according to the present invention
Design ensures that water is located at the lower part of pipeline for a long time as far as possible.In this way, enough effective cross sections of pipeline are maintained, so that
Its function as overflow pipe may be implemented in valve body.
In one embodiment, wall extends to sealing element since its lower end with continual vertical development length, and wall is in institute
State at lower end formation discharge outlet, the continual vertical development length of wall by for horizontal liquid stream provide through-flow channel according to
Around the rotation angle change of vertical direction.In this way, the continual vertical development length of wall refers to what wall extended along the vertical direction
Length, in the vertical development length, wall is extended continuously since its lower end.Generally, the lower end of wall is not necessarily identical
Extend at absolute vertical height, but is likely to be extended at different absolute vertical height according to rotation angle.Particularly, may be used
Make wall restriction conduit directly on horizontal scale on its entire continual vertical development length.Particularly, can make wall from its
Lower end starts to extend to sealing element vertically incessantly, especially directly limits out pipeline on its entire vertical scale.It is overall
On, wall can be made fully, to be i.e. exclusively arranged in below sealing element.In one embodiment, wall has the section of circular ring shape.One
In embodiment, the section of wall reduces from top to bottom at least range selector, especially entire where all through-flow channels
Reduce in vertical portion.
In one embodiment, through-flow channel is formed so as to be arranged in wall and correspondingly extend on rotation angle part
Through portion.In one embodiment, through-flow channel is embodied as making the lower end of wall according to the rotation angle around vertical direction along vertical side
To modified trend, so that through-flow channel is formed on the extension of lower end directly through the lower end of wall.Implement one
In example, wall can have through portion and the basis in the vertical direction of its lower end around the ruler of the rotation angle change of vertical direction
Degree.
In one embodiment, at least some of through-flow channel, particularly most of lower ends be formed as through wall,
In, wall extends since through-flow channel to sealing element on the continual vertical development length of wall.At this point, generally
It will be noted that " most of " of statement object obviously also include all objects.In the embodiment shown, the lower end of wall
With the scale along the vertical direction according to the rotation angle change around vertical direction, wherein through-flow channel by wall lower end
The scale along the vertical direction of the variation is formed.The embodiment obtains particular advantage, i.e., through-flow channel at its lower end not by
A part of wall limits, and therefore, also has downwards apparent other than horizontal component in the fluid stream by through-flow channel
In the case where vertical component, any power load will not be generated on valve body.Therefore it can be effectively avoided and close drain valve too early
Device.Further, since the design of the embodiment, can be achieved reduced horizontal cross-section surface in most descending for wall at elongated end, thus
It can be achieved to further decrease noise.
It is particularly preferred that the lower end of wall is designed to the form of the wave rotated around vertical direction, the amplitude of wave is along the vertical direction
Extend.The waveform is moved towards, particularly preferably setting is respectively provided with different size of different amplitudes, and wherein lower-magnitude is corresponding
Ground is arranged as adjacent with higher amplitude in the circumferential.In this way, adjacent amplitude indicates the lowermost of wall and the rotation around vertical direction
Gyration is related circumferentially-adjacent to extend downwardly maximum value.The slow closing of drain valve assembly can particularly efficiently be avoided
And the valve body during closing drain valve assembly is avoided to impinge upon on clack box in turn, because being drained when sealing element is apparently located close to it
When position when valve gear is in the closed position, due to when flow resistance increase on wall on the outside simultaneously and therefore wall with
When the accumulation of water may be present between the part around discharge outlet of clack box, through-flow channel is obtained by high-amplitude, so still
Certain horizontal liquid stream can be carried out, this has correspondingly slowed down the speed of valve body.Therefore it may make when valve body is close to its closing
When position, due to forming vortex between wall and discharge outlet edge, so can be gradually reduced, water enters in pipeline and valve body is to valve
The sinking of case can slow down.In addition, can thus be set as, the obvious offset of vertical of its closed position is left for valve body, can be obtained
The obvious common effective cross section of through-flow channel is obtained, so that a large amount of water may penetrate into pipeline.
In one embodiment, the vertical scale of at least part through-flow channel is that wall most descends between elongated end and sealing element
Vertical spacing at least 20%, particularly 20% to 80%.Due to being provided with the through-flow channel correspondingly longitudinally extended vertically,
Therefore, can ensure in the wide vertical displacement range of valve body by the horizontal liquid stream sum of through-flow channel especially
Into the fluid stream of pipeline.
In one embodiment, through-flow channel is arranged to be distributed in the vertical portion of wall, wherein wall in vertical portion with
Confining surface extends between through-flow channel, wherein all through-flow channels are formed together for the effective transversal of horizontal liquid stream
Face, the effective cross section be wall be located at vertical portion in the surface faced out at least 20%, particularly at least 30%,
Especially between 20% and 80%.The effective cross section of specific through-flow channel is along the vertical direction and perpendicular to bottom horizontal flow sheet direction
Extend, provides maximum cross section to this through-flow channel, the effective cross section is thus corresponding to the passage section.By all through-flow
The effective cross section that channel is formed together is the summation of the corresponding effective cross section of corresponding through-flow channel.The vertical ruler of vertical portion
Degree is limited by through-flow channel, because vertical portion is by upwardly extending the upper end of farthest through-flow channel and extending downwardly farthest lead to
The lower end of circulation road limits.The surface of wall faced out is wall entire between through-flow channel in vertical portion
Surface, the surface faced out are formed on the outside of wall and are formed in the side away from pipeline of wall in turn.Invention human hair
It is existing, by the effective cross section of through-flow channel and wall the surface faced out in vertical portion between through-flow channel it
Between indicated ratio can realize particularly well enter water in pipeline and at the same time valve body deceleration sink on clack box.
In one embodiment, the level of the horizontal scale of at least part through-flow channel, particularly most of through-flow channels
Scale reduces 60% or more of the vertical scale from bottom to top of through-flow channel along vertical direction.It is particularly preferred that extremely

Shape or tapered in form.The effective cross section of through-flow channel obviously refers to effective cross for the horizontal liquid stream by through-flow channel
Section.Since the horizontal scale of through-flow channel reduces upwards, on the one hand, the too fast sinking on valve body to clack box can be prevented, because
It is subjected to the enough thrust as caused by the water for flowing through through-flow channel for valve body, and on the other hand, it, can when reaching closed position
To ensure sinking and the deceleration of valve body, this hinders excessively heavy noise emission when reaching closed position.
In one embodiment, different through-flow channels is respectively equipped with correspondingly different vertical scales.It is particularly preferred that this
A little different through-flow channels are especially alternately distributed in the circumferential direction of wall.Being alternately arranged for different through-flow channels means have
There is the through-flow channel of different vertical scales to be disposed adjacently to one another.It is particularly preferred that effective cross of two adjacent through-flow channels
The ratio in section is at least 1.5 to 1.By the setting of the different through-flow channels, can particularly effectively prevent from issuing
Noise.The rotation symmetric design around vertical direction of wall is proved to be particularly advantageous.
In one embodiment, in first group of through-flow channel, the shape of each through-flow channel is in the first vertical ruler
The form of the triangle of degree, in second group of through-flow channel, the shape of each through-flow channel is in the second vertical scale
The form of triangle, wherein the second vertical scale is at least 1.5 times of the first vertical scale.It is particularly preferred that most of through-flow
Channel is all associated with this one of two groups.It is particularly preferred that most of through-flow channels are scattered in the circumferential so that two groups through-flow
Channel is alternately arranged in the circumferential direction of wall.As already explained, this of various sizes of through-flow channel is alternately arranged for subtracting
Small noise is particularly advantageous.
The obstruction section with confining surface of blockage element be pipeline at the height of blockage element, particularly
Block the effective cross section at the height in section 1/10th arrive one third to half, particularly 1/7th, wherein resistance
The horizontal centre of plug member is overlapped with the horizontal centre of pipeline.
In one embodiment, the obstruction section with confining surface of blockage element is the height in blockage element of pipeline
/ 10th of effective cross section locating, particularly at the height in obstruction section arrive half, particularly 1 to three/7ths
/ mono-.Wherein, height obviously refers to vertical direction.In this way, the effective cross section of pipeline indicates enabling flow through for pipeline
And pass through the cross section that pipeline is vertically flowed through with the obstruction section of confining surface of blockage element.In this regard, it should
It is noted that pipeline obviously can have different effective cross sections along its vertical scale.There is closing table for blockage element
The ratio between the obstruction section in face and the effective cross section of pipeline indicates, with particular reference to pipeline in the vertical of obstruction section
Effective cross section at height.In order to provide the obstruction section with confining surface, for example, blockage element can have pan portion,
In, pan portion can have such as through portion, wherein pan portion is designed to there is confining surface between through portion.In one embodiment,
In order to provide the obstruction section with confining surface, blockage element has continual closed cross on its entire horizontal scale
Section.Inventors have found that due between obstruction section and the effective cross section of pipeline with confining surface of blockage element
The ratio of instruction can avoid water by outlet and flow out pipeline too quickly, and can be simultaneously provided on the vertical scale of pipeline
Whole sufficiently large effective cross section to realize to be protected by the overflow of valve body.Particularly advantageously, blockage element at least exists
