Embodiment
In Fig. 1, should mix water valve and comprise outer valve 26, outer valve 26 is provided with cold inlet channel 19, hot inlet channel 20, flow control device inlet channel 21 and flow control device water outlet 22, spool is positioned at outer valve 26, cold inlet channel 19 is connected with the cold water inlet 13 of spool, hot inlet channel 20 is connected with the hot water inlet 14 of spool, the mixed water exports 16 of spool is connected with flow control device inlet channel 21 1 ends, be connected with flow control device 24 between flow control device inlet channel 21 the other ends and the flow control device water outlet 22, flow control device water outlet 22 is connected with outlet 23.
Shell 1 middle part of spool is provided with cold water inlet 13 and hot water inlet 14, and the left end of shell 1 is a mixed water exports 16.Box type piston 5 is positioned at shell 1 middle part, and adjustable lever 8 is positioned at shell 1 right-hand member.The right-hand member of adjustable lever 8 is connected with temperature adjustment handwheel 9, and the right-hand member of the left end of adjustable lever 8 and slide block 7 passes through threads engaged.Be equipped with bias spring 6 between the left end of slide block 7 and the box type piston 5.Shell 1 left end that is provided with mixed water exports 16 is built-in with metal temperature control spring 2, is equipped with hollow spring shield 4 between metal temperature control spring 2 and the box type piston 5, and hollow spring shield 4 right-hand members are provided with discharge orifice 17.
Box type piston 5, metal temperature control spring 2 reach in the inner chamber that constitutes with hollow spring shield 4 and are equipped with mixer 3, and the left end of mixer 3 is provided with water hole 18.Mixer 3 surfaces are provided with axial raised line.Mixer 3 can improve the mixed-precision of mixing water.
When rotation temperature adjustment handwheel 9 during to a certain scale position, when setting a certain mixing water temperature, adjustable lever 8 adjusting sliders 7 move, and compression bias spring 6 produces the size of box type piston 5,4 pairs of metal temperature controls of hollow spring shield spring, 2 compressive forcees.At rotary current adjusting handle 25 flow control device water outlet 22 is communicated with flow control device inlet channel 21, under cold inlet channel 19 and the hot inlet channel 20 energy normal water supply situations, use mixing water, enter through hot water inlet 14 this moment shell 1 lumen box type piston 5 hollows hot water with through the cold water of the discharge orifice 17 of cold water inlet 13, hollow spring shield 4 in hollow spring shield 4 hollows through mixer 3 fully essences mix.By the mixing water of metal temperature control spring 2 accurate sense temperature through the water hole 18, lumen mixed water exports 16, flow control device inlet channel 21, flow control device 24, flow control device water outlet 22, flow out outlet 23, the mixing water temperature that is flowed out is the temperature of the mixing water set.
