As shown in Figure 3, temperature adjustment valve pocket 20 up/down perforations, its inside limits the suitable temperature adjustment component main body of installing and is arranged in the temperature adjustment valve pocket 20, temperature adjustment valve rod 23 tops are stretched out by the top of temperature adjustment valve pocket 20, top headstock 24 cooperates with temperature adjustment valve rod 23 by trapezoidal thread, the top 25 is installed in top headstock 24 belows, and top headstock 24 and come directly towards 25 and up and down reciprocatingly moved by the driving of temperature adjustment valve rod 23 comes directly towards 25 lower ends downward and replaces with the thimble of thermosensitive element 31 and cooperate.Ring washer is arranged in the ring washer groove on temperature adjustment valve pocket 20 tops, the temperature adjustment valve rod 23, between temperature adjustment valve pocket 20 inwalls and temperature adjustment valve rod 23 outer walls oiled washer is set, between temperature adjustment valve pocket 20 inwalls and temperature adjustment valve rod 23 outer walls seal ring is set, temperature adjustment valve pocket 20 outer installment seal rings.

Wall below water outlet valve pocket 21 tops 25 is provided with water outlet 32, and flow switch portion 34 being set at water outlet 32 places, the valve rod linking mechanism bottoms that top headstock 24 and top 25 form are provided with downwards and can be sealed and matched with described flow switch portion and close the seal ring 41 of described water outlet 32.

The temp.-sensing head of thermosensitive element 31 is laid in the passage of thermosensitive element seat, thermosensitive element seat 26 tops operationally cooperate with thermosensitive element 31, thermosensitive element seat 26 upper outside provide spring actuating part 35, but these spring actuating part 35 outer rims cooperate with spring housing 22 slide relative ground, and seal ring are set therebetween; Valve pocket lower end (being the lower end of spring housing 22) is stretched out in thermosensitive element seat 26 bottoms, damping spring 27 is set in outside the thermosensitive element seat 26, damping spring 27 1 ends are replaced with the spring actuating part 35 of thermosensitive element seat 26 and are cooperated, the other end is replaced regulator 29 downwards, and cooperate gland nut 30 with regulator 29 axially adjustable be limited to periphery, thermosensitive element seat 26 bottom; Return spring 28 is set in outside the damping spring 27, and spring housing 22 bottoms provide return spring supporting portion 36, and return spring 28 1 ends cooperate with spring actuating part 35, and the other end cooperates with described return spring supporting portion 36.

Between regulator 29 upper ends and valve pocket lower end (being the lower end of spring housing 22) cold water intake 37 is set, regulator 29 lower ends are provided with hot water intake 38, provide on the thermosensitive element seat 26 and mix water passage 39, mix water passage 39 described cold water intake 37, hot water intake 38 are communicated with described water outlet 32.The described gland nut 8 that is positioned at described faucet subject 1 bottom is replaced with the compressing member 30 of described spool 2 lower ends, forms complete hot water and mixing water inlet channel.

In the present embodiment, the bottom of thermosensitive element seat 26 is offered is mixed into the mouth of a river 33, vertically offers cold water pathway 40 on the regulator 29, and cold water pathway 40 lower ends are with hot water intake 38 and be mixed into the mouth of a river 33 and be communicated with.The cold water pathway of vertically offering makes that cold water is that path through one comparatively crooked (corners that comprise two 90 degree) enters the mixed water passage in the thermosensitive element seat, through experimental results show that, comparatively Wan Qu water inlet path can be stablized the pressure of water inlet, plays certain weighing apparatus and presses effect; Certainly, be not precluded within the mode of offering cold and hot water inlet matching hole on the corresponding position of thermosensitive element seat 26 sidewalls respectively.

The water tap that present embodiment provides and the working procedure of spool are as follows: hot and cold water enters the cold water intake 37 and 38 inputs of hot water intake of described spool respectively after the hot and cold water water supply connector enters water arm into, the mouth of a river 33 that is mixed into via the spool bottom flows directly into valve core inside, fully mix and thermosensitive element 31 temp.-sensing heads of flowing through through overmulling water passage 39, the water outlet 32 from valve pocket waist (being water outlet valve pocket 21) flows out.Therebetween, water-exit temperature is subjected to the real-time monitoring of thermosensitive element 31, and thermosensitive element 31 cooperates return spring 28 drive regulators 29 to move up and down the input ratio that changes the hot water or cold water when supply water temperature or variation in pressure, thereby makes water-exit temperature keep constant.

The temperature adjustment principle of the single handle successive type thermostatic valve core that present embodiment provides is as follows: left rotation and right rotation temperature adjustment valve rod 23, temperature adjustment valve rod 23 is converted into the action up and down reciprocatingly of valve rod linking mechanism by the effect of trapezoidal thread, the thimble of valve rod linking mechanism and then promotion thermosensitive element 31, thereby regulate the sensitivity to heat of thermosensitive element, reach the purpose that temperature is set.

The flow switch principle of the single handle successive type thermostatic valve core that present embodiment provides is as follows: during from closed position rotation temperature adjustment valve rod 23 several angles, just open water outlet, further rotate in the process of temperature adjustment valve rod 23 afterwards, can realize temperature regulation (from low to high), but in this process, flow there is not influence (after being opened to a certain degree because of water outlet, its water flow is the solid flooding amount) substantially; When closing, backward rotation temperature adjustment valve rod 23 can be realized temperature regulation (from high to low) therebetween, behind described several angle, and then backward rotation one small angle, just close water outlet.

The foregoing description only is fully open unrestricted the utility model, in the utility model, described spool can be temperature adjustment spool or constant temperature valve core of buying from the market or the spool of regulating flow, or even can regulate the difunctional spool of flow and temperature; In described faucet subject 1 bottom sealing gasket 7 and gland nut 8 thereof etc. can be installed.Therefore, change or improvement for those skilled in the art are subjected to the conspicuous unsubstantiality that inspiration of the present utility model makes all belong to the scope that the utility model discloses.
