After adopting technique scheme, this constant temperature water-mixing valve can adapt to the variation of water inlet hydraulic pressure automatically, makes the temperature at water outlet place keep constant, need not frequently to regulate water temperature, and is very easy to use.
Description of drawings
Accompanying drawing is an embodiment's of the utility model a structural representation.
Embodiment
As shown in drawings, constant temperature water-mixing valve described in the utility model comprises the housing 4 that has cold water inlet 1, hot water inlet 2 and water outlet 3.Pipe 5 has certain clearance between interior pipe 5 and the housing 4 in being coaxially arranged with in the housing 4.The tube wall of interior pipe 5 is provided with hot water through hole 21 and cold water through hole 11, and on the outer wall of interior pipe 5, be provided with intermediate seal ring 6 between hot water through hole 21 and the cold water through hole 11, intermediate seal ring 6 becomes two water storehouses with the separated between interior pipe 5 and the housing 4.Cold water inlet 1, hot water inlet 2 lay respectively at the both sides of intermediate seal ring 6.The inner chamber of interior pipe 5 is separated into by demarcation strip 51 and mixes water cavity and regulate the chamber, the center of demarcation strip 51 has and is communicated with the through hole that mixes water cavity and regulate the chamber, hot water through hole 21 and cold water through hole 11 are positioned on the outer wall that mixes water cavity, be installed with mixed water cavity end cap 8 in the end of mixing water cavity by screw thread, mix on the water cavity end cap 8 and have ending cover hole, mix between water cavity end cap 8 and the housing 4 and be connected by seal ring; Mix in the water cavity and be fitted with temperature-sensitive bar 7, temperature-sensitive bar 7 adopts the structure of hollows, and the heat sensitive material that expands with heat and contract with cold easily is housed in its cavity, as temperature-sensitive paraffin etc.The front end of temperature-sensitive bar 7 is installed motion bar 71, and motion bar 71 can produce the axial stretching action with expanding with heat and contract with cold of heat sensitive material.Be provided with temperature-sensitive rod seal ring between the outer wall of temperature-sensitive bar 7 and the inwall of mixed water cavity, temperature-sensitive bar 7 is provided with the through hole together with two ends, is provided with return spring 9 between temperature-sensitive bar 7 and the mixed water cavity end cap 8; Mix water cavity end cap 8 places and be provided with outlet valve 81.Be provided with adjustable lever 41 in regulating the chamber, the inner of adjustable lever 41 is resisted against on the temperature-sensitive bar 7, and the outer end and the spiral regulating device of adjustable lever 41 are in transmission connection.
The effect of spiral regulating device is to rely on the principle of screw propulsion to determine the initial position of adjustable lever 41, and the concrete structure of spiral regulating device can have multiple.As shown in drawings, the push rod 43 that this spiral regulating device comprises the guide pin bushing 42 that is sleeved on adjustable lever 41 outsides, is connected with adjustable lever 41 by screw thread, the outer surface of adjustable lever 41 is the polygon prism shape, the guide pin bushing 42 of Pei Heing has the inner chamber of polygon prism shape with it, can move axially between adjustable lever 41 and the adjustable lever 41 like this and can not rotate relatively, fixedly connected positioning ring 44 on the guide pin bushing 42, the terminal fixedly connected temperature adjustment knob 45 of push rod 43.
During use, the cold water that enters by cold water inlet 1 enter by cold water through hole 11 mix in the water cavity, the left side of temperature-sensitive bar 7; The hot water that enters by hot water inlet 2 enter by hot water through hole 21 mix in the water cavity, the right side of temperature-sensitive bar 7; The cold water in the left side of temperature-sensitive bar 7 can enter the right side by the through hole on the temperature-sensitive bar 7, mixes with hot water, and mixed warm water is sent from water outlet 3 through outlet valve 81 by mixing the through hole on the water cavity end cap 8 again.Outlet valve 81 can adopt various existing valve mechanisms, as spiral valve, ceramic changeover valve, solenoid valve or the like.The effect of temperature detection is played on the right side of temperature-sensitive bar 7, in the time of the temperature drift of mixing water, heat sensitive material in temperature-sensitive bar 7 inner chambers expands, motion bar 71 Shens are long, because the adjustable lever 41 of left end is fixing, will promotes temperature-sensitive bar 7 in the time of motion bar 71 elongations and move right, temperature-sensitive seal ring on temperature-sensitive bar 7 outer walls blocks a part with hot water through hole 21, be equivalent to reduce hot water inlet's flow, thereby reduced the ratio of hot water, reduced water temperature.Otherwise when the temperature of mixing water was on the low side, temperature-sensitive bar 7 was moved to the left, and cold water through hole 11 is blocked a part, thereby reduced the ratio of cold water, improved water temperature.Reach the purpose of self adaption, constant temperature by such principle of expanding with heat and contracting with cold.
The effect of spiral regulating device is in initialization, by adjustable diameter and screw adjusting adjustable lever 41 is fixed on a suitable position.
