Fig. 2 shows the cross section of the distributing box according to second embodiment of the invention, for the sake of clarity removes some parts.
Detailed description of the invention
Reference numeral 1 in Fig. 1 represents the distributing box of the compound for kind of the liquid of two under different temperatures as a whole, in the embodiment illustrated these two kinds of liquid be heat with cold domestic water.Distributing box 1 connects cold water feed arm 2; Hot water feed arm 3; And the commingled water conveying arm 4 of tap 5 is installed.Distributing box 1 also can only distribute cold water or hot water.
Distributing box 1 comprises allocation units 6, and for controlling the control setup 7 of allocation units 6.In the embodiment of figure 1, distributing box 1 comprises two main supplying ducts 8, these two main supplying ducts 8 are respectively used to arm 2 to be connected to arm 4, and arm 3 is connected to arm 4, and in use these two main supplying ducts 8 respectively flow through cold water and hot water; Along two apportioning valves 9 of corresponding main pipe 8; For side by side controlling the double acting hydraulic cylinder 10 of two apportioning valves 9; For two subsidiary conduits 11 of hydraulic control cylinder 10; And for along the flowing of subsidiary conduit 11 rearrange liquids and two switching control pilots 12 of hydraulic control cylinder 10 thus.
Apportioning valve 9 is identical, and each apportioning valve comprises: valve body 13; And closer 14, closer 14 is removable relative to valve body 13 and operated by double acting hydraulic cylinder 10.
These two switching control pilots 12 are identical, and each switching control pilot comprises: valve body 15; Closer; And actuator 17, described actuator 17 is preferably bistable electromagnetic valve.
Say roughly, allocation units 6 are roughly symmetrical relative to plane A.And main pipe 8 has corresponding entrance 18, described entrance 18 is arranged symmetrically relative to symmetrical plane A, and converges in single outlet 19, due to structure reason described in outlet 19 slightly to depart from relative to symmetrical plane A.
Allocation units 6 comprise: the barrier film 20 of locating along symmetrical plane A; And two housings, 21, two housings 21 define at least part of of two guiding pieces 22 of the closer 14 for corresponding proportion valve 9, hydraulic actuating cylinder 10 and main pipe 8 and subsidiary conduit 11.The internal chamber of hydraulic actuating cylinder 10 is divided into two parts by barrier film 20, and is connected to this two closers 14, and these two closers 14 extend and align along axis B on the opposite side of barrier film 20.
Allocation units 6 comprise two the symmetrical plates 23 being mounted to respective housings 21, and described symmetrical plate 23 limits the valve body 13 of apportioning valve 9 and the part of main pipe 8 and subsidiary conduit 11.Allocation units 6 also comprise two symmetrical lids 24, the valve body 15 of these two symmetrical lid 24 limiting control valves 12, for holding and locking two seats 25 of the actuator 17 of control cock 12 and the part of main pipe 8 and subsidiary conduit 11.Allocation units 6 also comprise the sealing binding 26 of locating near guiding piece 22 along housing 21, and described sealing binding 26 has the respective openings 27 of aliging with guiding piece 22, to allow closer 14 passing through in hydraulic actuating cylinder 10 inside.Allocation units 6 also comprise two boiler check valve 28 of locating near outlet 19 along corresponding main pipe 8; And two boiler check valve 29 at hydraulic actuating cylinder 10 place are positioned at along corresponding subsidiary conduit 11.
Barrier film 20 is elastomeric, and according to the pressure be applied on the apparent surface of barrier film 20, in the change position, inside of hydraulic actuating cylinder 10.These closers 14 of pressure official post on the opposite face of barrier film 20 side by side move along D1 direction or D2 direction, with the flowing increased in an apportioning valve 9 and the flowing reduced in another apportioning valve 9.Pressure on barrier film 20 opposite face and the elasticity tension of barrier film 20 can make barrier film 20 and form state of equilibrium along the closer 14 that axis B is assemblied in barrier film 20.
Subsidiary conduit 11 is bypass manifolds, and bypass manifold from corresponding main pipe 8 branch, and is again joined with them after the corresponding supply portion of the internal chamber of hydraulic actuating cylinder 10.Pressure in arm 2 and 3, boiler check valve 29 and control cock 12 determines the pressure condition in two parts of the chamber of hydraulic actuating cylinder 10.
In the embodiment shown, control setup 7 operates in a feedback mode, and control setup 7 comprises: along the temperature sensor 30 of conveying arm 4; And control unit 31, control unit 31 is for the temperature that records based on temperature sensor 30 and control described control cock 12 based on the given target temperature that can input at the user interface (not shown) of control unit 31.
Reference numeral 32 in accompanying drawing 2 embodiment indicates distributing box integrally, and this distributing box is designed to operate as gauging device.In this case, distributing box 32 is positioned at a feed arm 2 and and carries between arm 4, different from distributing box 1, distributing box 32 comprises a main pipe worked 8, apportioning valve 9 and a boiler check valve 28, and comprises allocation units 33 and the control setup 34 for controlling allocation units 33.
Allocation units in Fig. 2 embodiment 33 are similar with allocation units 6, but different from the structure of the housing 35 and 36 capturing barrier film 20, and housing is replaced with housing 21, and one of to replace in closer 14 with closer 37.
Allocation units 33 comprise an entrance 38, and two main pipe 8 fluids are connected to entrance 38 and exit 19.
No matter how, one in two main pipes 8 is for good and all closed by closer 37 in the position of closer 37.
Except in allocation units 33, liquid only to flow with except the position of hydraulic control cylinder 10 and closer 14 along a main pipe 8 along two subsidiary conduits 11, allocation units 33 operate in the mode identical with allocation units 6.
Control setup 34 is with the operation of feedback pattern, and described control setup 34 comprises: sensor 39, preferably flow detector; And control unit 40, control unit 40 is for control cock 12 and given value (such as target flowing), and this given value can input at the user interface (not shown) of control unit 40.
Distributing box 32 can be designed to different from the embodiment of Fig. 2 significantly, and the embodiment of Fig. 2 only briefly illustrates the micro-structure needed for distributing box 32 be converted to for measuring a kind of liquid by the distributing box 1 being used for mixing two kinds of liquid and changes.As shown in contrast, distributing box 32 and 1 shares multiple parts.Especially, it should be noted that in fact gauging device distributing box only can comprise a main pipe, its subsidiary conduit is bypass manifold.
The present invention has multiple advantage.Substantially, directly supplied by output liquid pressure for the energy operating apportioning valve, this means that only consumptive use is to control the energy of flow of liquid along subsidiary conduit.And because this utilizes two switch electromagnetic valves with bistable actuator (only needing very short energy pulse to change the state of control cock), the energy ezpenditure for control dispenser is very low.
Constructively, distributing box is made up of plastics and rubber components; And the most expensive part is control cock, the motor that this control cock controls than coder is in general more cheap.
Flow of liquid along subsidiary conduit is very little, and can ignore relative to the flowing along main pipe, therefore on fluid exit temperature or flowing, does not have noticeable effect.However, distributing box is also equipped with feed back control system to revise temperature and/or flowing.
In addition, as described in shown two embodiments, dispensers according to the invention is not only of many uses but also easily produce.
Significantly, change can be made to the present invention under the prerequisite not departing from the protection domain that claims limit, and the distributing box of mixer function can also to be used to beverage dispensing applications.
