Embodiment
The present embodiment is implemented under premised on technical solutions of the utility model, give detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Fig. 1 is overall structure sectional side view of the present utility model, consults this figure below and is illustrated.
Described is a kind of control valve for outdoor mist cooling, as shown in Figure 1, described in the present embodiment, outdoor mist cooling control valve structure comprises: (1) cooling water outlet pipe, (2) collector mat, (3) cooling channel, (4) piston, (5) arch hole, (6) intake pipe, (7) valve housing bearing, (8) outlet pipe, (9) paddle hole, (10) shape memory alloy spring, (11) shape memory alloy spring fixed end, (12) collector mat fixed end.Collector mat (2) top center has a circular hole, and this circular hole is for connecting cooling water outlet pipe (1), and the cooling water outlet pipe (1) of attachment portion is provided with seal ring.The profile of collector mat (2) is a hollow cylinder wide at the top and narrow at the bottom, the top (7) of valve housing bearing is fixed in lower end, wherein collector mat fixed end (12) is screwed, and the joint of valve housing bearing (7) top and collector mat (2) lower end is lined with encapsulated coil.There is a cooling channel (3) at piston (4) center as the passage of collector mat (2) interior water circulation.There is the cold spring (10) stretching the marmem of round trip memory of pyrocondensation be fixed between collector mat (2) inner tip and piston (4) upper top.Arch hole (5) height of piston (4) inside is in the same size with intake pipe (6) internal diameter, and during valve closes, arch hole (5) top is no more than bottom outlet pipe (8) internal diameter.The stroke of shape memory alloy spring (10) is less than the height of the interior arch hole (5) of piston (4).There is a segment distance piston (4) bottom to arch hole (5) bottom, this segment distance adds that the total length of intake pipe (6) thickness is valve opening water intake and water outlet unobstructed distance, and the water in this segment distance in intake pipe (6) cannot enter in collector mat through cooling channel (3).Only had this segment distance cooling channel (3) just can receive the pressure flow just flowing in collector mat in intake pipe (6) portion.
As a reasonable example of the present utility model, the circulating water of collector mat (2) flows into the keying of control valve by cooling channel (3).
First, shape memory alloy spring fixed end (11) is welded in collector mat (2) top stand-by, then it is stand-by that shape memory alloy spring fixed end (11) is welded in piston (4) top.So far, shape memory alloy spring (10), collector mat (2) and piston (4) are integrated.
Secondly, be fixed on by cooling tube in cooling channel (3), then piston (4) is put into valve housing bearing (7), intake pipe (6) and outlet pipe (8) are connected to paddle hole.
Finally, between collector mat (2) and valve housing bearing (7), seal ring has been padded.With screw, collector mat fixed end (12) is fixed.In collector mat (2), fill water from collector mat (2) center hole, then cooling water outlet pipe (1) is fixed in collector mat (2) top center hole, assembled to this.
When water in collector mat (2) is subject to external high temperature, water in collector mat (2) is heated, when exceeding the phase transition temperature of shape memory alloy spring (10), there is deformation in shape memory alloy spring (10), heat shrinkable, contraction is divided into two stages, first stage: without hindrance stage, water in intake pipe (6) enters collector mat (2) without cooling channel (3), only through outlet pipe (8) water outlet, second stage: when piston (4) rises to certain altitude, the pressure that cooling channel (3) is subject to intake pipe (6) injects cooling water in collector mat (2), due to when water temperature is more than 4 DEG C, the density that water temperature is high is larger, because the water temperature of cooling water is higher than 4 DEG C, so when injecting cooling water in collector mat (2), cooling is the water temperature upwards slowly reduced from bottom in collector mat (2), water simultaneously in collector mat (2) flows out through process spraying from cooling water outlet pipe, after collector mat (2) interior water temperature lowers, there is deformation in shape memory alloy spring (10), meet cold elongation, piston (4) moves downward, the anhydrous circulation of valve closing, in collector mat (2) again through external heat said process repeatedly.Like this, control valve just can open and close by intermittent type, has effectively like this saved water resources.
