In addition,, in Fig. 2, show the situation of the aperture full cut-off of throttling arrangement.
As shown in the figure, throttling arrangement 100 has: main body 1, connects the first stream 2 and the second stream 3; Valve chamber 14, is formed on main body 1 inside and is communicated with the first stream 2; Valve seat 10, is formed on valve chamber 14 and has the throttle orifice 11 being communicated with the second stream 3; Valve body 4, freely advances and retreat and arranges towards the throttle orifice 11 of valve seat 10, and the aperture of adjusting joint discharge orifice 11.
In addition, throttle orifice 11 is suitable with " opening of valve seat " of the present utility model.
In addition, on the top of valve body 4, have stepper motor 20, this stepper motor 20 consists of stator and the rotor that links via not shown travel mechanism and valve body 4.The rotation of this stepper motor 20 is converted into by travel mechanism the distance of going forward side by side, and valve body 4 (above-below direction) movement vertically carrys out the aperture of the opening of control valve seat 10.
In main body 1, be formed with the main body bearing portion 9 of supporting valve body 4.Main body bearing portion 9 is by forming with lower member: main body stream 13, be communicated with the second stream 3 and throttle orifice 11, and for cold-producing medium (fluid) circulation; Valve body supporting, with hole 12, embeds and has valve body leading section 7.Valve body supporting is formed by embedded hole with hole 12, and this embedded hole has the slightly large internal diameter of external diameter than the valve body leading section 7 of valve body 4, and the valve body leading section 7 of valve body 4 is free to slide and is inserted into, thus, and with 7 sliding-contacts of valve body leading section and support valve body 4.
In addition, main body bearing portion 9 and throttle orifice 11 devices spaced apart ground configurations are communicated with a plurality of main body streams 13 between throttle orifice 11 and main body bearing portion 9 by this interval.
(flowing of cold-producing medium)
Below, about the mobile of the cold-producing medium in throttling arrangement 100, describe.
As shown in Figure 2, during full cut-off, the pin portion of valve body 46 and valve seat 10 butts are also held with the state of close contact.
Passing through the rotation of stepper motor 20, when valve body 4 is moved upward, valve body 4 is moved upward.Thus, the pin portion 6 of valve body 4 and the flow path area between valve seat 10 change, and flow is conditioned (first order throttling).Now, from the first stream 2, towards the cold-producing medium of the second stream 3, from the outlet side of throttle orifice 11, to each main body stream 13, shunt and arrive the second stream 3.In addition, from the second stream 3, after the cold-producing medium of the first stream 2 is divided to a plurality of main body streams 13, between main body bearing portion 9 and throttle orifice 11, collaborate again, arrive throttle orifice 11.
And, then valve body 4 is moved upward, in the pin portion 6 of valve body 4 and the situation of the flow path area maximum between valve seat 10 (standard-sized sheet aperture), by throttle orifice 11 limited flows (second level throttling).
In addition, passing through the rotation of stepper motor 20, when valve body 4 is moved downwards, valve body 4 slides mobile downwards.And, pin portion 6 and valve seat 10 butts of valve body 4, and keep with the state of close contact, full-shut position become thus.
The cold-producing medium of flow throttling device 100 sometimes vapor phase refrigerant is sneaked in liquid phase refrigerant as foam.When this gas-liquid mixed refrigerant passes through throttling arrangement 100, become the reason of noise sound.The main cause of noise sound clearly, for there being the foam of vapor phase refrigerant, especially exists large foam to become problem.
First, before the cold-producing medium sound countermeasure of explanation present embodiment, based on example in the past, problem is described.
(example in the past)
Figure 13 is the cutaway view at the main position of throttling arrangement in the past.In Figure 13, the situation that the aperture that shows throttling arrangement is full cut-off.
As shown in figure 13, in the throttling arrangement of example in the past, compare with embodiment 1 of the present utility model, valve body leading section 7, main body bearing portion 9, valve body hole 12, a plurality of main body stream 13 for supporting are not set.
At this, in the past in the throttling arrangement of example, using cold-producing medium from the first stream 2 to the mobile direction of the second stream 3, as positive direction, flow, using cold-producing medium from the second stream 3 to the mobile direction of the first stream 2 as flowing in the other direction.
And, at this, in the past in the throttling arrangement of example, about positive direction, flow and flow in the other direction, in the situation that the aperture of regulation is provided, the analysis result of the average velocity field of the differential pressure of regulation as shown in Figure 14, Figure 15.
Figure 14 is the positive direction flowing velocity distribution of throttling arrangement in the past.
As shown in figure 14, in the first stream 2, valve chamber 14, the speed of cold-producing medium is low.In the stream of the narrow zone between pin portion 6 and valve seat 10, the speed of cold-producing medium uprises, and along pin portion 6, with coniform, flows with narrowing down.If flow out from this narrow zone, enter in the second stream 3, but owing to thering is inertia, so flow with coniform with narrowing down.Its result, kinetic energy collects, and refrigerant velocities uprises.In addition, while there is pressure oscillation at the position with throttle orifice 11, this impact that other flow of refrigerant are brought is flowed in the direction of collecting, so very large at each because be.Centered by throttle orifice 11, in the second stream 3, refrigerant velocities is very high.
Figure 15 is the opposite direction flowing velocity distribution of throttling arrangement in the past.
As shown in figure 15, in most region, the speed of cold-producing medium is low.In the second stream 3, throttle orifice, refrigerant velocities is little.In the stream of the narrow zone between pin portion 6 and valve seat 10, the speed of cold-producing medium uprises, along pin portion 6 with coniform expansion flow.If flow out from this narrow zone, enter in valve chamber 14, but owing to thering is inertia, so with coniform expansion flow.Its result, kinetic energy diffusion, thus refrigerant velocities is low.In addition, even there is pressure oscillation at the position with valve chamber 14, this impact that other flow of refrigerant are brought is also because be in the direction of leaving at each mobile phase, so little.
Above, can observe and the positive direction mobile phase ratio shown in Figure 14, the region that mobile this side's of the opposite direction shown in Figure 15 refrigerant velocities uprises is few, and cold-producing medium sound is low.In the result of actual observation, with positive direction mobile phase ratio, this side's of flowing in the other direction cold-producing medium sound is also little.That is to say, in order to suppress cold-producing medium sound, as the flowing of the fluid of Figure 15, make fluid mobile of throttling arrangement inside become flowing with respect to direct of travel expansion.
(flow of refrigerant in present embodiment)
Below, about the flow of refrigerant in present embodiment 1, describe.
In the throttling arrangement 100 of present embodiment 1, also using cold-producing medium from the first stream 2 to the mobile direction of the second stream 3, as positive direction, flow, using cold-producing medium from the second stream 3 to the mobile direction of the first stream 2, as opposite direction, flow.
In the throttling arrangement 100 of present embodiment 1, about positive direction, flow and flow in the other direction, in the situation that the aperture of regulation is provided, the analysis result of the average velocity field of the differential pressure of regulation as shown in Figure 5, Figure 6.
Fig. 5 is the positive direction flowing velocity distribution of the throttling arrangement in embodiment 1 of the present utility model.
As shown in Figure 5, in most region, the speed of cold-producing medium is low.In the first stream 2, valve chamber 14, the speed of cold-producing medium is low.In the stream of the narrow zone between pin portion 6 and valve seat 10, the speed of cold-producing medium uprises, and along pin portion 6, with coniform, flows with narrowing down.If flow out from this narrow zone, owing to thering is inertia, so flow with coniform with narrowing down.But, owing to there being valve body leading section 7, so flow, can not collect to central authorities.And, by a plurality of main body streams 13, thus, flow divided, and cold-producing medium flows to the direction of disperseing.
In addition, when the position with throttle orifice 11 exists pressure oscillation, this impact that other flow of refrigerant are brought exists, if but pass through than the abundant short path of the diameter of throttle orifice 11, arrive a plurality of main body streams 13, thereby pressure oscillation can not influence each other.In a plurality of main body streams 13, certainly, pressure oscillation can not influence each other.
Like this, during the positive direction of the throttling arrangement 100 in the embodiment 1 shown in Fig. 5 flows, with the positive direction mobile phase ratio of the throttling arrangement in the past shown in Figure 14, the region that refrigerant velocities uprises is few, and cold-producing medium sound is suppressed.
Fig. 6 is the opposite direction flowing velocity distribution of the throttling arrangement in embodiment 1 of the present utility model.
As shown in Figure 6, in most region, the speed of cold-producing medium is low.In the second stream 3, a plurality of main body stream 13, throttle orifice 11, refrigerant velocities is little.In the stream of the narrow zone between pin portion 6 and valve seat 10, the speed of cold-producing medium uprises, along pin portion 6 with coniform expansion flow.If this narrow zone flows out, enter in valve chamber 14, but owing to thering is inertia, so with coniform expansion flow.Its result, kinetic energy diffusion, thus refrigerant velocities is low.In addition, even there is pressure oscillation at the position with valve chamber 14, this impact that other flow of refrigerant are brought is also because be in the direction of leaving at each mobile phase, so little.Like this, during the opposite direction of the throttling arrangement 100 in the embodiment 1 shown in Fig. 6 flows, become the mobile roughly the same average velocity field of opposite direction with the throttling arrangement in the past shown in Figure 15.
Above, the throttling arrangement 100 of present embodiment 1 is between throttle orifice 11 and the second stream 3, to be formed with a plurality of main body streams 13 that are communicated with throttle orifice 11 and the second stream 3.Thus, by effectively making flow of refrigerant disperse, reduce fluid energy, and can reduce the region that refrigerant velocities uprises, can suppress the increase of pressure oscillation, and can reduce cold-producing medium sound (fluid sound).
(flow path areas of a plurality of main body streams 13)
In throttling arrangement 100 in present embodiment 1, as shown in Figure 4, the total of the flow path area of a plurality of main body streams 13 is larger than the flow path area of throttle orifice 11.
Thus, even if the aperture of throttle orifice 11 changes to standard-sized sheet from full cut-off, a plurality of main body streams 13 can not become the main cause that determines flow yet.Therefore, for example, even if be provided with the throttling arrangement 100 of present embodiment 1 of a plurality of main body streams 13 and the throttling arrangement in the past that a plurality of main body streams 13 are not set, co-exist in same refrigerating circulatory device, because discharge characteristic is roughly common, so can also reduce manufacturing cost.
(flow path length of a plurality of main body streams 13)
Fig. 7 is the skeleton diagram of the effect in a plurality of paths of throttling arrangement of explanation embodiment 1 of the present utility model.
Fig. 7 (a) represents throttling arrangement in the past, shows the flow path length La situation (Da > La) shorter than the closest-approach distance Da of a plurality of main body streams 13 of a plurality of main body streams 13.
Fig. 7 (b) represents the throttling arrangement 100 of present embodiment 1, shows the flow path length Lb situation (Db < Lb) longer than the closest-approach distance Db of a plurality of main body streams 13 of a plurality of main body streams 13.
As shown in Figure 7 (a), than closest-approach distance in short-term, the advancing property (straight Jin) of the flow of refrigerant from a plurality of main body streams 13 flow out is low for the flow path length of a plurality of main body streams 13, and cold-producing medium flows in expansion.
On the other hand, as shown in Figure 7 (b) shows, when the flow path length of a plurality of main body streams 13 is longer than closest-approach distance, the advancing property of the flow of refrigerant from a plurality of main body streams 13 flow out is high, advances until the distance that adjacent a plurality of main body streams 13 flow of refrigerant is each other mixed is longer than Fig. 7 (a).
Like this, advance until between the distance that flow of refrigerant each other of adjacent a plurality of main body streams 13 is mixed, due to dispersion flows, thus Speed Reduction, thus after flow of refrigerant mixes, the impact bringing to pressure oscillation diminishes.Therefore, can access the effect of further inhibition cold-producing medium sound.
(arriving the distance of the throttle orifice 11 of a plurality of main body streams 13)
Fig. 8 is the cutaway view at main position of the throttling arrangement of embodiment 1 of the present utility model.
As shown in Figure 8, in the throttling arrangement 100 of present embodiment 1, the distance W from the end of throttle orifice 11 sides of a plurality of main body streams 13 to valve seat 10 forms littlely than the A/F R of throttle orifice 11.
When distance W is elongated, along the pin portion 6 of valve body 4, with the coniform cold-producing medium flowing, collect in central authorities with narrowing down, or occur chaoticly, there is the distribution change, pressure oscillation of refrigerant velocities and produce cold-producing medium sound.
In present embodiment 1, due to distance W ratio open width, R is little, thus can suppress from the end of throttle orifice 11 sides of a plurality of main body streams 13 to the flow of refrigerant valve seat 10 collect or chaotic, can further suppress cold-producing medium sound.
(other structure example of throttling arrangement 100)
Fig. 9 means the figure of other structure example of the throttling arrangement of embodiment 1 of the present utility model.
As shown in Figure 9, also can omit valve body leading section 7, main body bearing portion 9, valve body supporting with hole 12, at a plurality of main body streams 13 of surrounding's formation of central portion 17.In such structure, also can bring into play above-mentioned effect.
In addition, in present embodiment 1, to form the situation of a plurality of main body streams 13 in main body 1, be illustrated, but the utility model is not limited to this, also can with main body 1 split form.For example, also can on columned parts, form a plurality of main body streams 13, by this columned parts partition distance W be configured in the second stream 3 sides of throttle orifice 11.
Figure 10 is that the explanation retardance of throttling arrangement is, the figure of the generation of eddy current.
As shown in figure 10, at the cold-producing medium that has passed through a plurality of main body streams 13, during to the interior outflow of the second stream 3, exist and the retardance of flow of refrigerant occurs, the situation of eddy current.Sometimes the retardance of such flow of refrigerant, eddy current become the reason of cold-producing medium sound.
Figure 11 is the cutaway view at main position of the throttling arrangement of embodiment 2 of the present utility model.
As shown in figure 11, the throttling arrangement 100 of embodiment 2 of the present utility model is on the basis of the structure of above-mentioned embodiment 1, at main body bearing portion 9(central portion) the second stream 3 sides, be provided with the central portion from main body bearing portion 9() stationary parts 15 that stretches out to the second stream 3.
Thus, pass through the cold-producing medium of a plurality of main body streams 13 along the flow path between stationary parts 15 and the inwall of the second stream 3, can suppress the retardance of flow of refrigerant, the generation of eddy current.Therefore, can suppress cold-producing medium sound.
In addition, as shown in figure 11, the shape of stationary parts 15 have along the circulating direction of a plurality of main body streams 13 from the end of main body bearing portion 9 to the cone shape of the second stream 3 side hole enlargements, the cold-producing medium logical for the inwall effluent at the second stream 3 spreads, and has the cone shape of undergauge after the inwall with the second stream 3 separates predetermined distance.
