The utlity model has following advantage:
1. the cold and hot switching mixing valve that relates to of the utility model has two water intakes, two water outlets, itself has cold liquid recovery approach, has solved the technical problem that a certain amount of cold liquid that flows out earlier when mixing valve of the prior art uses not have utilization just to be wasted;
2. the cold and hot switching mixing valve that relates to of the utility model, when being lower than predetermined temperature, cold liquid-inlet is closed, and discharges cold liquid, gets into collecting box and recycles; When being in preset temperature, flow out use, realized the effect of constant temperature feed flow through mixing the liquid outlet.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is the structural drawing of cold and hot switching mixing valve;
1 is valve body, and 2 is reset spring, and 3 is second baffle, and 4 is the second solution stopping device, and 5 is first baffle plate; 6 is heat responsive element, and 7 is the first solution stopping device, and 8 for mixing the liquid outlet, and 9 is connecting rod, and 10 is cold liquid import; 11 is first through hole, and 12 is second through hole, and 13 is the hydrothermal solution import, and 14 is cold sap cavity; The flow direction is shown in arrow among the figure.
Fig. 2 is the structural drawing of another kind of cold and hot switching mixing valve; 15 for forcing handle.
Embodiment
It is as shown in Figure 1,
When the temperature that flows to from hydrothermal solution import 13 is lower than the deformation temperature value of memory alloy spring 6; Memory alloy spring 6 is contraction state; This moment is because the effect of the elastic restoring force of reset spring 2; Promote second baffle 3 to left movement, force the first solution stopping device 7 to block first through hole 11 on the hydrothermal solution body cavity, flow can not flow out through A; Second piston 4 leaves second through hole 12 of the cold sap cavity of adjustment sleeve simultaneously, and flow flows out through B, flows to cold liquid collecting box, reaches the technique effect of collecting cold liquid energy saving.
Higher as the liquid Wen Wendu that flows into hydrothermal solution import 13, and when meeting or exceeding the deformation temperature value of memory alloy spring 6, deformation take place in the memory alloy spring 6 of spring-like; Promote first baffle plate 5 to second motion; Promptly promote piston rod 9 and move right, force the first solution stopping device 7 leave on the hydrothermal solution body cavity first through hole 11, flow flows out through the A chamber; Compression also force in the reset spring 2 second piston 4 block on the adjustment sleeve second through hole 12, flow can not flow out from the B chamber.Open cold liquid import 10 simultaneously, and regulate cold liquid feed liquor flow, cold liquid and hydrothermal solution are mixed, make mixed liquid reach suitable serviceability temperature, flow out through mixing liquid outlet 8.Certainly,, can not mix, directly from through mixing liquid outlet 8 outflows with cold liquid if when the hydrothermal solution temperature is not very high (such as being lower than 40 degree).
As shown in Figure 2, regulate on the head pressure handle is set, can spool be moved in runner, through operating this handle, spool is realized the sealing A channel, opens the B passage; Perhaps seal the B passage, open A channel, and needn't the liquid body Influence of Temperature.
Above embodiment's purpose is to explain the utility model, and the protection domain of unrestricted the utility model, all application that come by the utility model simple change all drop in the protection domain of the utility model.
