Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Fig. 1,4, regulating handle 1 top is spline, bottom is that inwall is the cavity of internal thread, outside thread is arranged at double-screw bolt 2 tops, bottom is outer-hexagonal shape, regulating handle seat 3 is that inside is cavity, there is water outlet 31 lower end, regulating handle 1 is connected with double-screw bolt 2 by screw thread and pacifies shape and is contained in the cavity of regulating handle seat 3, the spline of regulating handle 1 stretches out the upper end circular hole of regulating handle seat 3, in the cavity of regulating handle seat 3, the position corresponding with the outer-hexagonal shape of double-screw bolt 2 bottoms is interior hexagonal configuration, and interior hexagonal is combined with outer-hexagonal but is unfixing dead.On lower shell body 7, there are cold water inlet 71, water inlet of hot water 72, its periphery is provided with filter screen 14, plunger 9 and spring 12 are arranged on lower shell body 7 the insides successively, the inward flange of plunger 9 upper limbs and lower shell body 7 inwalls is conflicted, lower surface and spring 12 are conflicted, the other end of spring 12 is against on base 13, and base 13 is connected and fixes with lower shell body 7 by screw thread.Directional post 10 is mounted and fixed on the middle part of temperature-sensitive assembly 8 by screw thread, movement rod 11 is arranged on the upper end of temperature-sensitive assembly 8, this three forms an assemblying body, is arranged in regulating handle seat 3, and the outer periphery of directional post 10 just contact with the inwall of regulating handle seat 3 but be not tight dead.Lower shell body 7 is connected and fixes with regulating handle seat 3 by screw thread, and after both install, temp.-sensing head 81 and the plunger 9 of temperature-sensitive assembly 8 just offset.Adjusting ring 5 upper ends are splines, lower end is outside thread, closing circle 6 upper inside wall is internal threads, it is interior hexagonal configuration that inwall is come off duty, closing circle 6 is connected with the outside thread of Adjusting ring 5 by internal thread, and being enclosed within the periphery of regulating handle seat 3, the interior hexagonal of closing circle 6 be combined with the outer-hexagonal of regulating handle seat but is tight dead, prevents from closing enclosing 6 rotations when adjusting.There is mixing water water outlet 31 regulating handle seat 3 lower ends, rotation Adjusting ring 5, and the removable circle 6 of closing, plays adjusting, opens, closes mixing water water outlet effect.Upper shell 4 is enclosed within the outside of Adjusting ring 5, and there is the protruding step of Inner upper end, can pin Adjusting ring 5, and lower end has screw thread be connected and fix with lower shell body 7, and middle have mixing water water outlet 41 in the position corresponding with regulating handle seat 3.
By rotation regulating handle 1, make double-screw bolt 2 produce displacement, synchronous make movement rod 11, temperature-sensitive assembly 8, plunger 9 produce corresponding displacement, movement by plunger between cold water inlet 71, water inlet of hot water 72, can regulate hot water or cold water's water inlet ratio, carry out the temperature control benchmark of regulating thermostatic spool with this; Under certain ambient conditions, in the time that mixing water water-exit temperature is higher, the temperature sensing material expanded by heating that temperature-sensitive assembly is 8 li, can promote movement rod 11, reverse promotion temperature-sensitive assembly 8 and plunger 9 are shifted to hot water inlet 72, reduce hot water flow, increase cold water flow, work to turn down water-exit temperature; Otherwise in the time that mixing water temperature is on the low side, the temperature sensing material that temperature-sensitive assembly is 8 li is met cold contraction, in movement rod 11 retraction temperature-sensitive assemblies 8, under the elastic force effect of spring 12, temperature-sensitive assembly 8 and plunger 9 are shifted to cooling water inlet 71, reduce cold water flow, increase hot water flow, work to heighten water-exit temperature.The screw thread of Adjusting ring 5 is plus thread, in the time will reducing water flow, rotates counterclockwise Adjusting ring 5, close circle 6 can produce away from Adjusting ring 5, near lower shell body 7 upper surfaces, reduce water outlet gradually, until close water outlet completely; In the time will increasing water flow, the Adjusting ring 5 that turns clockwise, closing circle 6 can, thereupon away from lower shell body 7 surfaces, near Adjusting ring 5, produce and increase gradually the effect of water outlet, until be adjusted to maximum value.
As shown in Figure 1, 2, the top, cross section of boss type seal ring 15 is semicircle, bottom is square, semicircle diameter length is less than the square length of side, upper surface forms step position, upwards, inwardly, outwards forms outstanding position, and there is inside Baltimore groove 73 lower shell body 7 upper ends, the outside outstanding position of boss type seal ring 15 is embedded in Baltimore groove 73, projects upwards position and closes circle 6 formation sealings.
As shown in Figure 2, there is outwards outstanding outward flange 32 at the position that regulating handle seat 3 contacts with boss type seal ring 15, and this outward flange 32 is pressed in the inside outstanding position of boss type seal ring 15, forms further fixing boss type seal ring 15.
As shown in Fig. 1,4, the filter opening of filter screen 14 is rhombus.
Above are only embodiment of the present utility model, design of the present utility model is not limited to this, and all equivalence or simple change of doing according to described structure, feature and the principle of the utility model design, are included in the protection domain of the utility model patent.
