Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Fig. 1 is mixed water valve schematic top plan view, and Fig. 2 is the cross-sectional schematic of mixed water valve dividing plate, and Fig. 3 is for mixed water valve is along two water-inlet cavitys and be positioned at the cross-sectional schematic of the through hole on water-inlet cavity.
In conjunction with shown in Fig. 1 to Fig. 3, a kind of mixed water valve, comprising: T-shaped valve casing 1, and described valve casing 1 two ends are water-inlet cavity 2, and described valve casing 1 the 3rd end is water chamber 3; Dash area in dividing plate 4(Fig. 2), be positioned at the intersection of described water-inlet cavity 2 and water chamber 3, and described water-inlet cavity 2 is separated with water chamber 3; Mixing chamber 5, on described dividing plate 4, described mixing chamber base plate 51 is provided with positioning hole 511 and a plurality of through hole 512, and described through hole 512 is communicated with water-inlet cavity 2, water chamber 3 respectively; Spool (not shown), is installed in described mixing chamber 5, for controlling being communicated with of through hole 512 and water-inlet cavity 2 and water chamber 3 on described base plate 51; Positioning hole 511 on described base plate 51 is blind hole, and is arranged on water chamber 3; Described water chamber 3 cross sections between described water-inlet cavity 2 are trapezoidal.Certainly, described trapezoidal be not that strict geometry is trapezoidal, but according to actual conditions, trapezoidal by four angle circular arcs.
Described two water-inlet cavitys 2 are provided with water intake 21, are respectively cold water inlet and water inlet of hot water.3 of described water chambers are provided with water outlet 31.
Wherein, described dividing plate 4 is two, in water-inlet cavity 2 and water chamber 3 intersections, two water-inlet cavitys 2 are cut off symmetrically, the cold water that enters and hot water can not directly be rushed touch mixing from two water-inlet cavity 2 water intakes 21, but through hole 512 from mixing chamber 5 base plates 51 enters mixing chamber 5, mix again.This kind of design, has effectively avoided, because of hot water or cold water's hydraulic pressure difference, and directly rush the high side of easy generation hydraulic pressure while touching mixing, the low side of hydraulic pressure being pushed down and causing hot water or cold water to mix uneven phenomenon.Meanwhile, because hot water or cold water all enters mixing chamber by through hole, therefore, by spool, control the inflow that size can be controlled hot water or cold water of opening of through hole, thereby control the mixed water temperature of hot water or cold water.
Described positioning hole 511 is two, is positioned at side by side on water chamber 3.The location of described positioning hole 511 when spool is installed, also can according to actual needs, only design single or multiple; If only design one, only positioning hole need be designed to non-circular, as rectangle or ellipse or triangle, as long as can play spool positioning action.
Described positioning hole 511 designs are above described water chamber 3, and not only when spool is installed, location is convenient, and just in case crackle or perforation appear in positioning hole 511, also can not cause seepy question, guarantees the normal use of mixed water valve, thereby reduces the number of rejects and seconds rate.
Described through hole 512 is three, respectively two water-inlet cavitys 2 is communicated with mixing chamber 5 with mixing chamber 5, water chamber 3.Described through hole 512 is for each water cavity of conducting, after hot water or cold water being intake mix, can flow out.According to actual needs, number of openings is not limit, and can design a plurality of water inlets or a plurality of water outlet through hole, and preferably three, lay respectively on the water-inlet cavity 2 of cold water, the water-inlet cavity 2 of hot water and water chamber 3, water-inlet cavity 2 is all communicated with mixing chamber 5 with water chamber 3.
Described mixing chamber 5 cross sections are circular, and are provided with screw thread at jointing.Described mixing chamber 5 is connected with outside depotition cock or gondola water faucet by screw thread, easy to use.
Described water chamber 3 is provided with reverser 32.Described reverser 32 is for selecting water outlet direction, and when reverser is pressed downwards or upwards pull up, water flows out from water outlet 31; When reverser changes position, depotition cock or gondola water faucet that water connects from mixing chamber 5 tops flow out.
The utility model also provides a kind of mixing water water tap, and described mixing water water tap only need be arranged on depotition cock on the mixed water cavity of above-mentioned mixed water valve and can make.
Mixed water valve described in the utility model specific embodiment, by positioning hole is arranged on water chamber, has avoided occurring because of positioning hole the seepy question that cracking causes; Meanwhile, by the water chamber Cross section Design between the water-inlet cavity of both sides in echelon, while making to manufacture described mixed water valve, the lead to the hole site being communicated with water-inlet cavity does not need separately to establish a core rod, but directly adopt single water-inlet cavity core rod, and greatly simplified designing for manufacturing, reduced cost of production.
The utility model specific embodiment also provides a kind of mixed water valve mould, and as shown in Figure 4, this mould, comprises a patrix 61 and a counterdie 62, and described patrix 61 coordinates the T-shaped valve casing profile of formation with counterdie 62; Two water-inlet cavity core rods 63, are positioned at the cavity both sides that described patrix 61 and counterdie 62 form, and are used to form water-inlet cavity; One water chamber core rod 64, is positioned in the middle of described two water-inlet cavitys, and the cross section of described water chamber core rod 64 is trapezoidal; One mixing chamber core rod 65, between described water chamber core rod 64 and counterdie 62, is used to form mixed water cavity, through hole and positioning hole.It is trapezoidal that described trapezoid cross section is not proper geometry, but trapezoidal by trapezoidal four angle circular arcs.
Because the cross section of described water chamber core rod 64 is no longer traditional rectangle, but trapezoidal, be that constriction lower end, upper end is widened, recycle the thickness space of dividing plate simultaneously, can make easily whole water-inlet cavity core rod 63 vertically put into mould, and mixing water valve mould unlike the tradition of Fig. 5, its water chamber core rod 75 must be designed to combination mold core 73, combination mold core 74 combination mold core dimerous, just can put into.
Mixed water valve core rod described in the utility model specific embodiment, owing to adopting single core rod design, not only simple in structure, and when casting forming, be not easy to occur core rod and burst by copper water, make foundry goods occur the problem of slag inclusion, sand holes and shrinkage porosite, effectively improved yield rate, reduced cost of production.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not within departing from spirit and scope of the present utility model; can make possible change and modification, the scope that therefore protection domain of the present utility model should be defined with the utility model claim is as the criterion.
