Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, embodiment:
The present invention is designed to a kind of temperature automatically controlled mixed water valve.It adopts a kind of shape memory alloy temperature control spring and sliding valve core, biasing spring, be composed in series bias voltage formula device, utilize the Young's modulus of shape memory alloy material that the characteristic of notable change takes place near characteristic temperature, the cold water that independently enters valve pocket and the ratio of hot water are automatically adjusted, water temperature to mixing water forms a kind of reverse feedback control mode, thereby reaches the requirement of constant temperature water supply effectively.Because the shape memory alloy temperature control element has the dual functions of temperature-sensitive and executive component concurrently, the shape memory alloy temperature control element directly is placed on the outlet port of mixing water simultaneously, therefore, this control mechanism can be made rapid reaction to the minor variations of mixing water temperature, and carries out corresponding reverse feedback and regulate.
Referring to accompanying drawing, shape memory alloy temperature control spring 19 and sliding valve core 17, biasing spring 14 and their positioning mandril 13, outlet pipe 21 are connected into bias voltage formula controlling mechanism.They are inserted in the valve pocket of inner valve body 6, and inner valve body 6 has two openings, respectively cold water and hot water are introduced valve pocket.Sliding valve core 17 is a hollow, its cylindrical is fixed with seal ring 16, the cold water and the hot water that enter valve pocket are separated, cold water can only be flow through in the center hole by spool, near the position at shape memory alloy temperature control spring 19 places, mix with the hot water that enters valve pocket.Like this, shape memory alloy temperature control spring 19 is just in time sensed the temperature of mixing water.Height according to temperature, the strength of shape memory alloy spring 19 changes, so elongate or shorten variation, thereby promote sliding valve core 17 mobile positions, make the size of opening of the cold water enter the chamber valve and hot water change, enter the cold water of chamber valve and the quantitative proportion of hot water thereby change, reach the purpose of regulating mixed water temperature.Because this controlling mechanism is arranged to negative feedback mode, thereby guarantee to mix the thermostatic characteristics of water outlet.
Outer valve 18 is responsible for cold water and hot water are introduced inner valve body 6 respectively, seal ring 11, seal ring 15, seal ring 20 are arranged between them, cold water and hot water are separated, and their termination takes bayonet socket to be fixed together, and takes engage thread to be fixed together with outer cover 8.
Adjustable lever 3 is housed in the inner valve body 6, and has seal ring 7, the inner end of adjustable lever 3 to have screw thread to cooperate with nut 12.The outer end of adjustable lever is passed inner valve body 6 and is cooperated with the square hole of adjusting knob 1, and has lid fixed thereon 2 to prevent that it from skidding off.
The other end card of outer valve 18 has dynamic porcelain piece 30, and is lined with sealing gasket 28 between them.Blend water pipe 21 and pass dynamic porcelain piece 30 from the center, and seal ring 27 is arranged, prevent to mix that water outlet is counter flows.Dynamic porcelain piece 30 is worn into mirror-smooth with the surface of contact of definite ceramic chip 24.With the fixed base 22 of definite ceramic chip, and shell 10 usefulness screws 31 are fixed up, and dynamic porcelain piece 30 and definite ceramic chip 24 can be pressed together.Between fixed base 22 and the valve seat 23 seal ring 25 is housed, seal ring 26, seal ring 29.Valve seat 23 is respectively equipped with the inlet opening of cold water, hot water and the exit orifice of mixing water.One end of shell 10 is fixed on the valve seat 23 through gland nut 32.The other end of shell 10 fastens the shaft shoulder of outer valve 18, can rotate within the specific limits between them.The exterior edge face of shell 10 is provided with rotating locating blocks 9, is used for determining the slewing area of whole valve body.There is the cone gear form striped end of inner valve body 6, and the knob core 5 that is fixed in the knob 1 has the inner conical striped, Returnning spring 4 is arranged separately between them.
During real work, knob 1 is pressed to inner valve body 6, make knob core 5 be close to inner valve body 6.At this moment rotary knob 1, and then outer valve can rotate in shell 10 with interior integral body, and drive dynamic porcelain piece 30 rotates on definite ceramic chip 24, thereby reaches the effect of switch water.And unclamp knob 1 (not pressing to inner valve body 6), and turning knob 1, then adjustable lever 3 and then rotates, nut 12 moves axially, promote push rod 13 axial displacements, change the work cell distance of biasing spring 14 and shape memory alloy temperature control spring 19, thereby play the effect that blends coolant-temperature gage of regulating.
