Description

Control core for sanitary mixer valves

The present invention relates to a kind of control core of sanitary mixer valves, in valve, have a preferably plate shaped fixing control surface, can join with the water intake of valve.Water intake has a cold water open region and at least one hot water open region at least, and there is a preferably plate shaped chain of command, utilize the control of mixer controlling rod, do with respect to open region, have the motion of two degrees of freedom, according to the residing position of chain of command, or open region block, or be connected with at least one water outlet, to control the water yield and proportions of ingredients.

This mixed water valve belongs to known (DE-OS-2.756.784) originally.In this valves known, there is a fixing plate shaped disk, on it, have two water intakes, a supplying hot water use, another is for cold water.On the opposite of above-mentioned fixed disc, separately have one can translation and the disk of rotation, this movable disc can be blocked two water intakes completely or be completely open.Movable disc is rotated, can determine proportions of ingredients, and determine the total throughput of water during its translation.

Separately have a kind of known mixed water valve of one hand that also belongs to, the patent No. is DE-OS3.325.269, and the opening on the fixing chain of command of this valve, with the control of movable control disk outer rim.The water intake of hot water and cold water can have two openings of settling side by side.

The mixed water valve that this is known or have an inner edge control system or have an outer rim control system.

The shortcoming of inner edge control system is to have a sizable space.Control disk that can translation must be quite large, and the every side that makes to control mouthful, has the size corresponding with a certain certain openings and corresponding seal area.In addition, control mouth and at least must the spacing in one direction and between opening and opening have same size.Therefore this mixed water valve is under a certain given size, and the flow area of control means is relatively little, just needs to improve flow velocity and causes noise.

Known the above-mentioned type control system also has other shortcoming, and there is limitation the aspect that may use exactly, is difficult to adapt to various uses.

The problem that the present invention proposes is to provide the control core of the mixed water valve of a kind of single handle, and it is of many uses that it may have, for the past institute from failing the person of accomplishing.

According to the present invention, this problem has obtained solution, because the open region of movable chain of command and/or water outlet and/or shape have special arrangement and structure, forms two control system independent and that occasionally connect with machinery respectively.The control system of these two independent operations makes to control core can make many purposes.Therefore, such as can make two control system work simultaneously, increase the sectional area of liquid stream or passage, the increase of channel cross-sectional area, exceedes the single open region of single control system is amplified.But also can be by two control system for other All aspects of.For example, a control system is used for to top upper nozzle, and second control system is used for to side direction shower nozzle.In this case, two control system at any time can be simultaneously to a water outlet effect, and this water outlet and another water outlet cut off.The convenient part of doing is like this that two shower nozzles are not connected in the downstream of mixed water valve, and therefore, in the time that current are closed, the water in the upper nozzle of top can not flow out by side direction shower nozzle from water pipe.In addition, two shower nozzles have point other control system, just may make them have different blending characteristics.Therefore, for example, top upper nozzle is compared with side direction shower nozzle, can have different maximum temperatures, or different maximum proportions of ingredients.

Another feature that can obtain according to the present invention is that two control system can act on a common water outlet.This is not only conducive to increase cross-section area, and is conducive to special circumstances.For example meet the requirement of British standard(BS).These valves must ensure the only waterexit end at mixer, and hot water current and cold water current are mixed.According to the present invention, for example, why this object can reach, and is that hot water is by a control system control, another control system control for cold water, and the common water outlet that is positioned at mixer water outlet is by two system water supplies.

Another exploitation form of doing according to the present invention, movable chain of command has an outer edge of controlling, and realizes a control system, has again an inner sealing control edge, realizes second control system.Easy speech, the control core of realizing by the present invention, has an outer rim control system and an inner edge control system.

The fixing chain of command of each control system again can be under any circumstance, has respectively two open regions, and therefore each control system can respectively be carried out a temperature control.But, for example, in two control system, in two open regions of a system, also may only have hot water, or only have cold water.In continuous fluid heater, this possibility can be utilized, and produces favourable control characteristic.This heater is unmanageable especially.Because produce main pressure drop in continuous fluid heater, the hot water side of downstream valve contains minimum resistance.Can also imagine one in two control system only for cold water, for example in the time having initial high temperature in order to make temperature limiting.

The present invention also proposes, in each situation, two open regions are radially relative each other.

According to another kind of development form, can be connected with a water intake fixing chain of command, in this case, outlet current and import current, through same chain of command, are 180 ° of direction transformations.

The present invention also proposes: the current limliting face of preferably plate shaped control disk, be used as chain of command, at this moment, for example controlling disk with pottery is particularly suitable as chain of command.If disk and chain of command are flat, the one degree of freedom of controlling so disk is to rotate, and another degrees of freedom is to do translational motion.

The present invention also proposes: using the some of the opening communicating to relevant control disk as controlling edge.In this case, water is from controlling a side inflow opposite side of disk.Thereby in a region in water ramp metering core, the water flowing out from outer rim control system, also flows in this region of controlling core.

But the present invention can also further propose, a recess of a control edge restriction is supplied water to chain of command, and close towards the opposite side of controlling disk.Can especially simply water outlet and two control system be cut off like this, two control system can be acted on different water outlets.

Obtainable another feature according to the present invention, two control system have the control characteristic that part is identical at least, and therefore two control system can be opened water intake simultaneously.Also may two control system open, but the variation of the proportions of ingredients of a control system finishes early than another control system simultaneously.Also may make two control system successively open, there is an overlapping time centre.

The present invention also proposes, and there is roughly the same expanded angle open region in opposite directions.

According to the present invention, can also specify that there is different cross sections open region in opposite directions.But also can make them have identical cross section.

The present invention further proposes again, and preferably there is identical cross section two adjacent open regions, using controlling edge as a control system.

Hereinafter, will do comparatively detailed narration with regard to non-conditionality embodiment of the present invention and accompanying drawing, accompanying drawing thes contents are as follows:

Fig. 7 to 11 is fixing disk and the movable schematic diagram of controlling the various positions of disk controlled.

Fig. 1 is illustrated in the mixed water valve shell 11 of disconnection.Shell 11 has a shell bottom plate 12, has some water inlets 13 on it, and in Fig. 1, only one hole is visible, and has osculum 14.In shell 11, be embedded with one and control core 15, fixing with sleeve 16, with isolated with outside.Sleeve 16 relies on the screw thread 17 in its outside, twists and connects with the corresponding internal thread in shell central hole.

Core 15 also claims core cylinder, has at the bottom of core 19, on it porose some 20,21.Core cylinder also has the first sleeve pipe 22, from inserting wherein assembling set 23 above, for laying control unit 24.Top cover 25 is placed on from above above assembling set 23, and top cover inner edge is parked on the shoulder 27 on assembling set 23 tops.In Fig. 1, top cover 25 has outwardly directed bead 28 below, contacts with the bottom of sleeve 16.Sleeve 16 is just assembling set 23 like this, and by the bead 28 of lid, core jacket casing pipe 22 promoted downwards together, so just core 15 is fixed shell 11 is interior.In order to reach sealing, sleeve pipe 22 has an air ring 30, is placed in an all-round circular groove 29.Assembling set 23 is also by the air ring 32 of 31 li of circular grooves, and the inner sealing of sleeve pipe 22.

Assembling set 23 has an axial bore 33, and its outside and inner side expand, and at least one part in inner side is spherical in shape.The centre of operator 24 is roughly spherical part 34, is placed in the spherical part of axial bore 33.Below the spherical part 34 of operator 24, there is an adapter 35.Its section is approximately rounded in Fig. 1, and this adapter 35 watches from being the visual angle of 90 ° with Fig. 1, is rectangle, referring to Fig. 2.Adapter 35 is placed in the space that has respective shapes 36 of 37 li of driving components, and this driving component is arranged on 38 li of rings in sleeve pipe 22, can translation and rotation.When operator 24 is in the time that the axis perpendicular to Fig. 1 plane rotates, cause the translation of driving component 37, and operator 24 is in the time that the longitudinal axis of itself rotates, and causes rotatablely moving of driving component 37.Driving component 37 is controlled disk 39 with a pottery and is connected.The lower interface of the control disk 39 in Fig. 1, forms first chain of command.

Below activity control disk 39, place the fixing disk 40 of controlling, controlling fixing on core, second control surface of interface formation on it.The fixing control disk 40 illustrating in the drawings, be placed on core cylinder chassis 19 above.The upper outlet in 19Shang hole, core cylinder chassis 20,21, and the aperture 41,42 of controlling on disk 40 coincide.On core cylinder chassis 19 and below, around there is Sealing 43 in the aperture in hole 20,21.Movable disc 39 also has a through hole 44, and its shape will below describe in detail.

The part section that Fig. 2 presentation graphs 1 installs, the signal of watching from the direction vertical with Fig. 1.This direction, can see that the adapter 35 of operator 24 has the cross section of rectangle.And and driving component 37 in have the space 36 of corresponding construction seamless chimeric.On the lower surface of driving component 37, there are two microscler rib ridges 45, are embedded in 46 li of the movable grooves of controlling the respective shapes on disk 39 upper surfaces.Can make so the movable disk 39 of controlling, do the relative rotation of controlling disk 40 with respect to fixing.

Fig. 3 is the plan view on core cylinder chassis 19, and the disk that this chassis is circular, has protuberance 47 in its outer rim, pegs graft with the corresponding recesses in mixing valve shell 11.Each protuberance 47 has different width, thereby can prevent that core cylinder chassis from putting upside down insertion.

There is a center hole on core cylinder chassis 19, is circular port 21 under specific circumstances, referring to Fig. 1.Around center hole 21, there is aperture 48,49,50,51, form the upper outlet of Fig. 1 mesopore 20.Between 48,49,50,51 aperture, and the outside in these apertures, packing ring 43 inserted.As shown in Figure 1.Aperture 48 is positioned at that to be roughly 90 ° of circular core cylinder chassis 19 fan-shaped, and aperture 51 be positioned at relative 90 ° fan-shaped.Aperture 49 and 50 is also like this, relative on diameter mutually.Place with respect to aperture 48,49,50,51 is eccentric in hole 21, and all these apertures are curved layout roughly.

The shape in aperture 48,49,50,51, the shape in the aperture 41 on fixing control disk 40 of making peace is greatly consistent, and this is explained with reference to Fig. 4.Therefore,, by core cylinder chassis 19, just can form path fixing control between aperture on disk 40 or open region and mixing valve shell bottom plate 12.As seen from Figure 1, on mixing valve shell bottom plate 12, do not have and core cylinder chassis on the corresponding opening in hole 21, this is also feasible, this just does not need, with another core cylinder chassis 19, to end hole 21.In the time having specific use, can also use the core cylinder chassis 19 shown in Fig. 3, with mixing valve shell 11 combinations, and shell 11, as an example, aperture 48 does not have corresponding water intake.Like this, although all use all the time same control core, and likely obtain various proportions of ingredients.

Fig. 4 is a fixing figure controlling disk 40, and this disk is also circular, and has two protuberances 52 in being used as calmly.The fixing disk 40 of controlling has four apertures 53 to 56, its shape and 19Shang aperture, He Xintong chassis, position 48-51 correspondence.Aperture 53 is relative on diameter with 56, and aperture 54 is also relative on diameter with aperture 55.Controlling disk 40 also has central, circular hole 42, also referring to Fig. 1.Aperture 42 is eccentric placement a little.All there is roughly the same expanded angle in aperture 53 to 56, and the area in aperture 53 to 56 has different sizes.Between adjacent aperture 53,54 and adjacent aperture 55,56, draw a line they are separated, so aperture 53 is under any circumstance all similar to aperture 54, and aperture 55 is similar to 56.

The plan view of activity control disk 39 used in embodiment in Fig. 5 presentation graphs 1 and Fig. 2.This disk has central hole 44, with and the groove 45 of both sides, as shown in Figure 5.

The Lower Half of the control disk 39 in Fig. 5, taking edge 60 as periphery, is a circular arc.The first half of Fig. 5 control disk 39 is taking edge 61 as periphery, and its outer radius equates, but with the not concentric of edge 60 of Lower Half.Edge 61 accounts in the near middle of upper half part the scope at 90 ° of angles, is retracted into inwards and becomes curved edge 62. Opening 53,54 in edge 62 and Fig. 4, forms an outer rim control system jointly, hereinafter will have narration.

Control the lateral margin 63 in disk 39 apertures 44, and two other aperture 55,56 forms inner edge control system.

The drive manner of apparatus is as follows: water is shown in Fig. 1 by water intake 13(), through 19Shang hole, core cylinder chassis 20, flow in the fixing aperture 53,54,55,56 of controlling on disk 40.Due to the position difference of activity control disk 39, the scope of closing in these apertures can be larger or smaller.If open in these apertures at least part, current just flow out from aperture 53,54,55,56, by the center hole 44 of movable disc, or through the edge 62 of movable disc 39, flow into 64 li, the space of this disk top, then from space 64, along the sidewall direction of shell 11 to outflow, downward in the axial direction along shell edge again, flow out by the water outlet part 14 of shell bottom plate 12 again.In order to make water be more convenient for flowing out from shell 11, the chassis 19 of core cylinder and fixing control disk 40 are all fluted on this position, as shown in Fig. 3 and 4.

But, according to the control core shown in Fig. 1, in a kind of shell of different mixed water valve, lead to different streams.There is a center hole 21 on core cylinder chassis 19, and the center drilling 42 of fixing control disk 40 is just right, and this also can be for the shell of mixing valve, at this moment has a central water outlet hole that is arranged in the prolonged section in hole 21.So water can flow to by above-mentioned central water outlet mouth the outside of shell.In this case, can utilization activity control disk 139(profile type as shown in Figure 6), it is different from the control disk shown in Fig. 5, there is no the through hole 44 at center, and only has a space 144 at bottom opening.The shape in space 144 is in other side, all completely similar with the aperture 44 of the control disk 39 shown in Fig. 5, thereby the shape of lateral margin 63 is also identical.Therefore can obtain identical control characteristic.Outlet current only flow out by the center hole 42 of controlling disk 40 downwards.

The purposes of the control disk shown in Fig. 6 has many aspects.First be only to carry out a kind of control, for example, control hot water by groove 144 and the fixing center hole 42 of controlling disk, the control of cold water is by outer rim 62.So two current can merge at the water outlet of mixing valve.About mixing a bit at mixing valve water outlet, British standard(BS) has defined.

Can also utilize groove 144 and the apparatus of central water outlet mouth control such as side direction shower nozzle, top upper nozzle utilizes controls edge 62 and avris outlet 14 controls.These two control system have mechanical connection, in the downstream of mixed water valve, lead between the pipeline of independent shower nozzle and do not link.Therefore, current do not lead to the backflow of side direction shower nozzle from top upper nozzle.

Can also only there is the mixing valve of limited flow rate with the control of inner edge control system, such as the mixed water valve for washbowl and bidet.

Hereby, with reference to Fig. 7 to Figure 11, narrate the interaction of two control disks that are in harmonious proportion two current and set up water output.The movable rotation of controlling disk 39 or 139 can cause temperature variation, and the movable longitudinal translation of disk along microscler center hole 44 of controlling just can be selected water output.In Fig. 7, control disk and do counterclockwise to rotate and reached its final position, and do to upper left side translation simultaneously.The edge 63 in aperture 44 is opened the fixing aperture 56 of controlling disk 40 completely, and disk 40 and hot water are communicated.Control the control edge 62 in disk 39 outsides simultaneously, aperture 53 is completely open, and aperture 53 also communicates with the supply port of hot water.Therefore the meaning of this location is the maximum opening that maximum temperature is provided.If controlling disk 39 clockwise direction rotation again, just situation as shown in Figure 8.The aperture 55,56 on fixed disc is done in the opening of same degree in aperture 44, and the opening of roughly the same degree is done in 62Ye Ba aperture, edge 53,54.What Fig. 8 was represented like this is exactly the control core location of 50% proportions of ingredients.

What Fig. 9 represented is the movable disk 39 of controlling, and locates with respect to shown in Fig. 8, does counter clockwise direction rotation to a certain degree, also has some to right-hand translation simultaneously, thereby has set up compared with low discharge, comparatively gentle temperature.

If control disk 39 movable and do not rotate, and move down from position shown in Fig. 8, reach the position shown in Figure 10, at this moment valve is closed on the neutral position of temperature adjustment.Control disk 39 in this closed position, both can also can rotate to counter clockwise direction to clockwise direction, and valve keeps closing.

From Fig. 7 to Figure 11, can see: under any circumstance, the fixing perforate 53,54,55,56 of controlling on disk 40, all connects with same water intake.For example, in order to make specific use (while needing limit temperature), for example, also suitable to two apertures 53,54 and the connection of same water intake, for example connect with cold water.In the time using continuous fluid heater, be suitable for two apertures 53,54 all to connect with hot water, to reduce pressure drop.

Although in the embodiment of giving an example, for the aperture the 55, the 56th of inner edge control system, Mirror Symmetry, the aperture 53,54 of outer rim control system is also Mirror Symmetry, but in order to obtain specific control characteristic, it is also feasible that Mirror Symmetry arrangement is not done in aperture.The measure of doing according to the present invention can bring many advantages.To the space for controlling aperture, can utilize by optimized mode.Like this, compare with the traditional control system with identical core-tube structure, the throughput of water can be improved a lot.But in the time that water flow is only done to limited increase, flow velocity can be kept to very low, its result just can reduce noise.When valve is only when doing little water yield control, also can use same core cylinder, only a control system need be connected in this case.In practice, this is feasible and inconvenient.At this moment only control core need be inserted with to the mixed water valve shell of respective bore.Mat piece is still constant.Therefore,, under individual cases, can respectively inner edge control system or outer rim control system be done to functional element use.

Owing to being provided with a center hole in fixing control disk, if the top of activity control disk is closed, for example, close with transmission part, or just increase an extending portion under shed, just this core cylinder can be used as to closed system.So the discharge current of mixing water are parallel to feeding current direction current downflow.Save top cover or the reduction of activity control disk, just inner edge control system can be used as to open system.

The shape of change system, can make inner edge control system or outer rim control system have corresponding special mixed water form.So just can be by inner edge control system, or outer rim control system, or two systems are simultaneously, use as the various functional element of intended purpose.

Due to inner edge control system and outer rim control system intersection are controlled, for example only use inner edge system control hot water, outer rim system control cold water, just can meet the regulation of British standard(BS) about enclosed type inner edge control system.In the past, when this particular/special requirement only may go brimful condition to meet the regulation of British standard(BS) with special valve or accessory, this core cylinder can be for the mixing without pressurised boiler

Aspect continuous fluid heater, can also obtain another one advantage.The feature of this heating is, maximum Pressure Drop betides in heater itself, so the valve of connecting has liquid flowing resistance, is at least like this at hot water side.So also be suitable for cutting long-pending outer rim control system control at hot water side with maximum, and in inner edge control system control for cold water side.Due to water pipe in pressure roughly have inversely prroportional relationship, just may obtain again balanced control performance.

All these variant forms that may obtain are all the control disks by homeostasis, are just connecing in mode differently, and add a cover on internal control system by wish, coordinate with center round, form an airtight system.And the structure of all the other parts of ceramic disk and core cylinder remains unchanged.Change the mode connecting, can be by corresponding thorax in the shell of the direct below of core cylinder variation with realization be changed.
