Preferably, on connecting rod, the second solution stopping device both sides are fixed with first baffle plate and second baffle, Returnning spring one end face withstands second baffle, and first plate washer is withstood in heat responsive element one end.
Preferably, be provided with the groove that holds connecting rod in two ends of valve body, connecting rod can the one the second moves.
Preferably, be respectively equipped with first at the one the second two ends of valve body and regulate head and regulate head with second, connecting rod places first to regulate head and second and regulate in the central channel of head, connects sense and first and regulates head and second adjusting and join.
Preferably, be provided with adjustment sleeve at an end of valve body, cold liquid container places in the said adjustment sleeve; Be provided with seal ring between adjustment sleeve and valve body second end; Be provided with seal ring between the second adjusting head and the adjustment sleeve; Returnning spring and second baffle place in the adjustment sleeve; First baffle plate, heat responsive element, the first solution stopping device and the second solution stopping device place in the feed liquor body cavity; The heat responsive element very first time, the liquid interior with getting into valve body contacted.
Preferably, set point of temperature is the 30-45 degree.
Preferably, this valve is suitable for that liquid is flat to be used or vertically use, or with leading one, or be arranged separately in the pipeline.
The present invention has following advantage:
1. the cold and hot switching mixing valve that the present invention relates to has two water intakes, two water outlets, itself has cold liquid recovery approach, and having solved a certain amount of cold liquid that flows out earlier when mixing valve of the prior art uses does not have to utilize the technical problem that just is wasted;
2. the cold and hot switching mixing valve that the present invention relates to, 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
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
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 present invention, and unrestricted protection scope of the present invention, all application that come by simple change of the present invention all drop in protection scope of the present invention.
