Hereafter by the drawings and specific embodiments, the utility model is described further.
With reference to figure 1, a kind of large discharge double-control thermostatic spool, comprising:
The valve body 1 be made up of upper shell 11 and lower shell body 12, it has cold water inlet 121, water inlet of hot water 122 and blends the mouth of a river 123;
One thermosensitive element 2 with temperature-sensitive end and telescopic end, the perception of described temperature-sensitive end blends the water-exit temperature information at the mouth of a river 123, and passes to described telescopic end;
One to be arranged and can at the piston apparatus 3 of described valve inner movement with described thermosensitive element 2 interlock;
Described upper shell 11 is connected by a fixed base bar 13 with lower shell body 12, and one end of described fixed base bar 13 has binding thread 131; Described lower shell body 12 is connected with fixed base bar 13 by binding thread 131.Have between described upper shell 11 and lower shell body 12 gap be described in blend the mouth of a river 123, described lower shell body 12 periphery is parallel is provided with described cold water inlet 121, water inlet of hot water 122; Described upper shell 11 comprises a temperature-adjusting device 111 and flow opening device 112; Described temperature-adjusting device 111 regulates the position of described piston apparatus 3, thus changes the discharge area of cold water inlet 121, water inlet of hot water 122; Described flow opening device 112 regulates the relative position of upper shell 11 and lower shell body 12, thus blends the mouth of a river 123 described in opening or closing.
Above-mentioned a kind of large discharge double-control thermostatic spool, by arranging separate temperature conditions device 111 and flow opening device 112 on upper shell 11, changed the discharge area of cold water inlet 121 and water inlet of hot water 122 by temperature conditions device, thus reach the object changing and blend the mouth of a river 123 water-exit temperature.Regulated the relative position of upper shell 11 and lower shell body 12 by flow opening device, thus change the gap width between upper shell 11 and lower shell body 12, thus achieve the object of opening or closing and blending the mouth of a river 123.Two controlling devices are separate to be independent of each other, and structure is simply firm, effective.
Concrete structure is: referring to figs. 2 and 3, described flow opening device 112 comprises an adjustable lever 1121 and rotation seat 1122; Be wrapped in the outside of described fixed base bar 13 outside described adjustable lever 1121, the periphery of described adjustable lever 1121 is in transmission connection with rotation seat 1122 by the first transmission thread 1123; When rotating described adjustable lever 1121, rotation seat 1122 moves up and down under the drive of the first transmission thread 1123.
The bottom surface of described rotation seat 1122 is provided with a seal ring 1124; The end face of described lower shell body 12 is provided with a flange 124; When described rotation seat 1122 is moved downward to extreme lower position, described seal ring 1124 and flange 124 are fitted, described in blend the mouth of a river 123 and be closed.
A spline rod 1111 and guide rod 1112 is comprised with reference to figure 4 and described temperature-adjusting device 111; Described spline rod 1111 is located at the inside of fixed base bar 13 and is exposed the spiral shell head of spline rod 1111; Described guide rod 1112 and spline rod 1111 are in transmission connection by the second transmission thread 1113; Described thermosensitive element 2 is connected with guide rod 1112; When rotating described spiral shell head, guide rod 1112 moves up and down under the drive of the second transmission thread 1113, thus drives thermosensitive element 2 and piston apparatus 3 to move up and down.When piston apparatus 3 moves downwardly to extreme lower position, described water inlet of hot water 122 is fully closed, and blending the mouth of a river 123 water outlet is pure cold water, as shown in Figure 5; When piston apparatus 3 moves up to extreme lower position, described cold water inlet 121 is fully closed, and blending the mouth of a river 123 water outlet is pure hot water, as shown in Figure 6; When piston apparatus 3 is between extreme higher position and extreme lower position, cold water inlet 121 and water inlet of hot water 122 are opened simultaneously, and blending the mouth of a river 123 water outlet is mixing water, as shown in Figure 7.
In the present embodiment, the thermostatic control principle of thermosensitive element 2 is as follows: the described region of piston apparatus 3 between cold water inlet 121 and water inlet of hot water 122 is moved; When the perception of described thermosensitive element 2 blends the temperature drift at the mouth of a river 123, described telescopic end extends, described piston apparatus 3 moves towards the direction of water inlet of hot water 122, partial occlusion water inlet of hot water 123, the discharge area of water inlet of hot water is diminished, thus the flow of water inlet of hot water 122 is diminished; When the temperature that the perception of described thermosensitive element 2 blends the mouth of a river is on the low side, described telescopic end shortens, and described piston apparatus moves towards the direction of cold water inlet 121, partial occlusion cold water inlet 121, thus the flow of cold water inlet 121 is diminished.Therefore, by moving up and down of thermosensitive element 2 control piston device 3, conveniently can regulate the discharge area of cold water inlet 121 and water inlet of hot water 122, make the water-exit temperature blending the mouth of a river 123 keep constant.
The present embodiment also comprises following decision design:
In a preferred embodiment: the periphery of described piston apparatus 3 by two O shapes circles 31 and lower shell body inwall at the region conforms between cold water inlet 121 and water inlet of hot water 122.Place two O shape circles 31 and can strengthen leading role, prevent the piston apparatus 3 when hydraulic pressure increases or change suddenly from shake abnormal sound and bite etc. occurring.
Described piston apparatus 3 is connected by claw type guiding groove 32 with one end of described thermosensitive element 2.Because blocking of claw type guiding groove 32 pairs of thermosensitive elements 2 is less, the area that therefore thermosensitive element 2 contacts with mixing water just adds, and adds the temperature-control performance of thermosensitive element 2.
The outside of described thermosensitive element 2 is provided with a water-water jet 21, and one end of described water-water jet 21 offers a plurality of water passage hole 211 being communicated to described cold water inlet 121, water inlet of hot water 122, the other end of water-water jet 21 with blend the mouth of a river 123 and be communicated with.The mixing water mixing flowing through thermosensitive element 2 is like this more abundant, and temperature close to the water-exit temperature blending the mouth of a river 123, further increases the temperature-control performance of thermosensitive element 2 more.
Described piston apparatus 3 is connected by a tapering spring 33 with the inwall bottom lower shell body 12.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
