Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a cross-sectional schematic of the present utility model;

Fig. 2 is the structural representation of chuck.

With reference to Fig. 1, Fig. 2, this water-mixing valve core mainly is made of valve body 1, temperature control double-screw bolt, thermometer bulb compound body, wheel shape spool 16, spring 19.Valve body 1 is to connect to form by two sections, it has hot water inlet, cooling water inlet, the outlet of mixed warm water, the shape size of hot water inlet and cooling water inlet is identical, and filter screen 15 arranged, foreign material in the energy elimination water, its inner chamber is separated by wheel shape spool 16, is divided into mixing water cavity 20 and cold water cavity, and there is seal ring 14 its outside.The thermometer bulb compound body is connected to form by thermometer bulb 21 and push rod 13, be provided with and thermometer bulb 21 shell all-in-one-piece cams 18 in its joint, the top stem casing 17 that is connected on cam 18, push rod 13 withstand on the double-screw bolt trap 11 of temperature control double-screw bolt, thermometer bulb 21 is in and mixes in the water cavity 20, and push rod 13 is positioned at cold water cavity.Wheel shape spool 16 is connected on the top stem casing 17, its outer rim and valve body 1 inwall match, outer rim is between hot water inlet and the cooling water inlet, and therefore when it moved, import of hot water or cold water's import increased, another import just reduces, total opening section is constant, thereby reaches the purpose of constant current, and the scope that its outer rim moves is no more than water intake, there is the cold water through hole on one side at wheel shape spool 16 to another side, the cross section in this hole and generally be not less than cooling water inlet the cross section and.Place the temperature control double-screw bolt of valve body 1 one ends to be made up of adjusting nut 9 and the adjusting screw rod 5 that is complementary, adjusting nut 9 is in valve body 1 one ends, and the adjustable side of adjusting screw rod 5 is outside valve body 1.In the inner of adjusting nut 9 inner chamber is set, arranges within it by spring 10, double-screw bolt trap 11 through the firm self-insurance mechanism that constitutes the thermometer bulb compound body of jump ring 12 cards is installed.Spring 19 is enclosed within on the thermometer bulb 21, and an end heads on the other end of valve body 1, i.e. warm water waterexit end, and spring 19 the other ends head on cam 18, thereby guarantee that push rod 13 withstands on the double-screw bolt trap 11.The elastic force of spring 19 is less than the elastic force of spring 10.In the outer end of adjusting screw rod 5 an adjusting control mechanism is set, it is made up of chuck 2, dial 3, handwheel 4, is connected on the adjusting screw rod 5 through screw 6, and can regulate is controlled the water temperature between required 20～50 ℃.A security personnel mechanism that is higher than 38 ℃ of water temperatures is set between chuck 2 and handwheel 4, it be by be contained in button 8 on the handwheel 4, spring 7, and chuck 2 on baffle plate 22 constitute.8 rotation handwheels 4 can continue to regulate to high temperature as long as press the button during to 38 ℃.

Working principle: regulate temperature control double-screw bolt set temperature value on dial 3, open cold, hot-water switch enter it and mix in the water cavity 20.When entering the hot water temperature who mixes in the water cavity 20 when being lower than set temperature value on the dial 3, push rod 13 does not contact with double-screw bolt trap 11, and at this moment wheel shape spool 16 is static.When entering the hot water temperature who mixes in the water cavity 20 when equaling set temperature value on the dial 3, the temperature-sensitive thing of thermometer bulb 21 expands and promotes push rod 13 and double-screw bolt trap 11 just in time matches, and the wheel shape spool still is state of rest.When entering the hot water temperature who mixes in the water cavity when being higher than on the dial 3 set temperature value, temperature-sensitive thing in the thermometer bulb 21 continues expansion and promotes push rod 13, under the effect of top board 13 reaction forces, force thermometer bulb 21 pressure springs 19, and it is mobile together to drive wheel shape spool 16, hot water inlet is reduced, and cooling water inlet increases, and the through hole of cold water on wheel shape spool 16 in the cold water cavity enters mixed water cavity 20 to be mixed mutually with hot water.When the water temperature in mixing water cavity 20 equaled on the dial 3 set temperature value, the temperature-sensitive things in the thermometer bulb 21 just stopped expansion, and wheel shape spool 16 just is state of rest, and water intake also remains unchanged.When the water temperature in mixing water cavity 20 was lower than set temperature value on the dial 3, thermometer bulb 21 interior temperature-sensitive things became contraction, under the effect of spring 19, make thermometer bulb 21 be with wheel shape spool 16 to move round about, reach the increase hot water inlet, reduce cooling water inlet, thereby realize the purpose of constant temperature.The effect of self-insurance mechanism is: during set temperature value on regulating dial 3, when the temperature control double-screw bolt was advanced in valve body 1, spring 10 was compressed, and the thermometer bulb compound body is played a protective role.

In use, if when disconnected cold water takes place, the water temperatures in the mixing chamber 20 can raise rapidly, and the temperature-sensitive thing in the thermometer bulb 21 can rapid expansion, and under the promotion of push rod 13, thermometer bulb 21 drives wheel shape spools 16 pressure springs 19, can very fast hot water inlet be closed.If when generation hot water used up, the water temperatures of mixing in the water cavity 20 can reduce rapidly, the temperature-sensitive things in the thermometer bulb 21 shrink rapidly, and thermometer bulb 21 can move by very fast drive wheel shape spool 16 under the effect of spring 19, and cooling water inlet is closed.
