Described the 2nd porous part 13 is by the wire in prescribed level footpath stainless steel material for example, is entwined by irregular, or combined the forming of wire netting that is formed by the irregular wire netting that is entwined and rule braiding.Described the 2nd porous part 13 forms the density mesh by described wire and consists of, and it is discoid that the 2nd porous part is set to link to each other with described throttle part 12.
Described valve rod 9 in described space 93e successively with described the 1st porous part 11, described throttle part 12 and the 13 tight chimeric configurations of the 2nd porous part.Utilize the tip portion 93d1 of the described protuberance 93c of described valve rod 9, fixing to implementing riveted joint around described the 2nd porous part 13, and make described the 1st porous part 11, described throttle part 12 and the 2nd porous part 13 insert fixed configurations on valve rod 9.Fix by it, make access 94, described the 1st porous part 11 and described throttle part 12 (being described throttling path 12a) and described the 2nd porous part 13 consist of the coolant path of valve rod 9.
Next the action of solenoid valve 1 in the 1st mode of execution is described.
When electromagnetic coil 3 by going between 32 when being in the state of energising, produce the magnetic force of opposing compression helical spring 8 spring forces according to the energising of electromagnetic coil 3, thereby attractor 10 attracts core iron 6 downward directions, core iron 6 is in sleeve part 4 interior movements, and then valve rod 9 is attracted son 10 guiding and moves to seat portion 27.Be that valve rod 9 moves to closing the valve direction, the periphery valve face 93d of the 93b of wall section of the valve section 93 of valve rod 9 and the internal face close contact of seat portion 27, thereby make valve rod 9 seat in seat portion 27.The result as shown in Figure 4, solenoid valve 1 is for closing the valve state, valve rod 9 and the 1st porous part 11 and inflow side passage 22 relative to and dispose, thereby can close the valve operation by solenoid valve 1.
The valve state that closes as shown in Figure 4, the outflow side passage 23 of the inflow side passage 22 of import side pipe 25 and outlet side pipe 26 is communicated with by the 1st porous part 11 and intercommunicating pore 94 and throttling path 12a and the 2nd porous part 13.
Namely when freeze cycle in when running dehumidifying, refrigerant flows into from import side pipe 25, then flow into the 1st porous part 11 by intercommunicating pore 94, because the size of the 1st porous part 11 mesh is regularity and the uniformly multi-ply constructions that are made of sintered meshwork, so the refrigerant that flows into is slowed down, the flowing state of the gas-liquid 2 phase refrigerants in the refrigerant also forms and homogenizes, therefore, can be simple and definite make bubble sectionalization in the refrigerant.Because the 1st porous part 11 is by multi-ply construction, the direction that flows at refrigerant is provided with certain thickness, so can carry out for a long time the bubble sectionalization.Moreover, multi-ply construction is owing to be that large footpath (d1) wire forms the 1st wire netting 11A of few mesh amount (m1) and path (d2) wire (d1＞d2) forms many mesh amount (m2) (Construction integration that the 2nd wire netting (11B1 and 11B2) of m1＜m2) forms by sintering, so the 1st wire netting 11A is as the framework layer of described the 1st porous part 11, when refrigerant flows into, can be when guaranteeing the 1st porous part 11 intensity, because the upstream side that the 1st metal mesh arrangement flows at refrigerant, so the 1st wire netting 11A can make the 1st porous part 11 be difficult for producing distortion and crooked, therefore, can realize a kind of long lifetime the 1st porous part that can reduce the refrigerant flow noise.Consist of the 2nd wire netting 11B1 and 11B2 of multi-ply construction with the 1st wire netting 11A, owing to consisted of by mesh m2, so as the dispersion layer of the 1st porous part 11, can realize for a long time the stingy alveolation of bubble in the refrigerant after the sectionalization.
In addition, the 1st wire netting 11A and described the 2nd wire netting 11B1 and 11B2 are the stainless steel sintered meshwork, so, can realize heat-resisting quantity and the anti-deformability of the 1st porous part of described multi-ply construction.As a result, can realize a kind ofly can reducing the refrigerant flow noise, and then suppress the solenoid valve of noise producing.In addition, the described porous part 11 of the 1st wire netting 11A and described the 2nd wire netting 11B1 and the formed described multi-ply construction of 11B2, form discoid by punch process, because this discoid the 1st porous part is configured in the interior described space 93e of the 93b of wall section of described valve rod 9, so can realize a kind of noise reduction the 1st porous part 11 with high manufacturing accuracy and high work efficiency, thereby, this noise reduction porous part, not only production is good, low-cost, but also can be definite make the bubble sectionalization.As a result, have the solenoid valve 1 of described the 1st porous part 11, also can realize low cost, long lifetime and reduce the refrigerant flow noise.
Pressure pulsation has occured even flow into the gas-liquid 2 phase refrigerants that exist in the refrigerant of the 1st porous part 11, owing to can obtain the refrigerant that pressure pulsation homogenizes by described multi-ply construction, form successional pressure pulsation so flow into the refrigerant of throttling path 12a, therefore, can stablize and effectively carry out throttling by throttling path 12a, thereby can reduce the refrigerant flow noise.
In addition, become large even can grow up in the process that in throttling path 12a, flows by the bubble in the refrigerant after 11 sectionalizations of the 1st porous part or can grow up after by throttling path 12a and become greatly, but when the large bubble of change of growing up in the refrigerant flows into the 2nd porous part 13, can make it become large bubble sectionalization by the 2nd porous part.Namely because the 2nd porous part 13 forms the different wire netting of mesh density for the wire of stainless steel material by irregular braiding, therefore, flowing into grows up in the refrigerant of the 2nd porous part 13 becomes large bubble, by described mesh can be definite sectionalization, thereby the refrigerant flow noise in the time of can reducing by the 2nd porous part, the result makes refrigerant flow to outflow side passage 23, and is flowing out side pipe 26 interior flowing.
By the 1st porous part 11 and throttling path 12a, the pressure pulsation that produces because of the refrigerant flow rate change is inhibited, thereby can reduces pressure oscillation.As a result, because refrigerant can homogeneous 2 circulation circulation flow path 12a that celebrate a festival mutually can be inhibited so can realize a kind of pressure oscillation, and be difficult for producing noise, and can obtain to stablize a kind of solenoid valve of coolant throttle effect.
And, after the coolant throttle effect, even refrigerant flows out from throttling path 12a, bubble occurs to grow up when becoming large, because refrigerant flows to the 2nd porous part 13, so when refrigerant passes through the 2nd porous part 13, bubble in the refrigerant is segmented, thereby can reduce the flow noise of refrigerant.Therefore, can realize a kind of solenoid valve 1 that can under the prerequisite that reduces the refrigerant flow noise, stablize the dehumidifying operation.
In addition, as mentioned above, the metal net structure with density mesh that the 2nd porous part 13 forms for irregular braided metal line, but the present invention is not limited to this structure, also can be the braided metal line of rule and the meshed wire netting of tool that forms and above-mentioned irregular braided metal line and the structure with density mesh that the wire netting with density mesh that forms combines.By the 2nd porous part 13 as can be known, when the generation of the bubble in the refrigerant that throttling path 12a flows out growth becomes large, because the 2nd porous part can be the combination of the meshed wire netting of the formed tool of irregular braided metal line and the meshed wire netting of the formed tool of regular braided metal line, so, can make the mesh of the 2nd porous part be set to have the structure of density by this combination, therefore, by the 2nd porous part can be definite make in the refrigerant to grow up and become large bubble sectionalization.Therefore, can realize a kind ofly simply can reducing the refrigerant flow noise, and further suppress the solenoid valve 1 of noise producing.
To sum up, the solenoid valve 1 in the present invention's the 1st mode of execution when long-term the use, not only can reduce the flow noise of refrigerant, but also can realize and can stablize the exsiccation of throttling by certain carrying out.
When the electric current to lead-in wire 32 is disconnected, because attractor 10 does not produce magnetic force, attractor 10 loses the attraction force to core iron 6, so the core iron 6 in the sleeve part 4 is the urging force of compression helical spring 8 according to the spring force of compression helical spring 8, moves to attractor 10 reciprocal tops.Thereby valve rod 9 is in the inside of attractor 10 cylindraceous guiding and be moved upward with core iron 6, as shown in Figure 1, and the lift off a seat internal face of section 27 of the valve section 93 of valve rod 9.As a result, outflow side passage 23 is opening state, and refrigerant flow to through outflow side passage 23 and flow out side pipe 26, thereby the valve operation is left by solenoid valve 1, forms the valve state of opening without throttling action from flowing into side pipe 25 after inflow side passage 22 passes through seat portion 27.This is opened under the valve state, as shown in Figure 1, valve rod 9 is not to be arranged in valve chamber 21 refrigerants from the stream of inflow side passage 22 inflows, therefore, refrigerant can not flow into the 1st porous part 11, the throttling path 12a that is positioned on the valve rod 9, and in the porous part 13 formed coolant paths.
In the invention described above embodiment's the explanation, as shown in Figure 2, dispose described the 1st wire netting 11A of multi-ply construction and discoid described the 1st porous part 11 that described the 2nd wire netting 11B forms in the inner space 93e of described valve rod 9, in when configuration, with the described intercommunicating pore 94 of the described discoid side of described the 1st porous part 11 and described valve rod 9 relative to and dispose.
In addition, described the 1st wire netting 11A that consists of described the 1st porous part 11 is configured in refrigerant is flowed to described intercommunicating pore 94 by described inflow side passage 22 upstream side, by described the 1st wire netting 11A the situation of the bubble sectionalization in its refrigerant is described for above-mentioned refrigerant, but the present invention is not limited to this a kind of situation, and, when from the refrigerant of described intercommunicating pore 94 during by described the 1st porous part 11 sectionalization, above also can making its refrigerant import to that described the 1st wire netting 11A is relative with described the 2nd wire netting 11B below butt, to toss about namely.
