Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of orifice union, comprises throttle pipe 1 and throttling transition conduit 2; Wherein, orifice union compared to existing technology, in the utility model, adding throttling transition conduit 2, can be specifically the structural representation of the utility model orifice union see Fig. 1, Fig. 1, one end of this throttling transition conduit 2 is sheathed on the port of export of throttle pipe 1, its other end is then connected with evaporimeter 3, and the inner tubal wall of this throttling transition conduit 2 is arranged along the flow direction flaring of tube fluid, that is to say that the size of the interior caliber of throttling transition conduit 2 increases gradually.
The utility model in use, that is to say in process of refrigerastion, and refrigerant enters evaporimeter 3 from orifice union, and is the gas of low-temp low-pressure by the liquid gasification of low-temp low-pressure, with absorption refrigeration; Adopt the utility model, refrigerant first through throttle pipe 1, then enters evaporimeter 3 through throttling transition conduit 2, and namely refrigerant is before entering evaporimeter 3, has carried out injection and the evaporation of gradual-enlargement type in throttling transition conduit 2; In this process, the jet velocity of throttling transition conduit 2 pairs of refrigerants has carried out certain decay and weakening on the one hand, on the other hand, because the inner tubal wall of throttling transition conduit 2 is arranged along the flow direction flaring of tube fluid, the space of interior conduit is flaring, refrigerant can gasify step by step in throttling transition conduit 2, thus decreases liquid refrigerant, that is to say the liquid state amount decreasing refrigerant when entering evaporimeter 3.Therefore, refrigerant is after throttling transition conduit 2, and throttling transition conduit 2 decays and weakens the jet velocity of refrigerant, also reduces the amount of liquid refrigerants; Wherein, decay and weaken the jet velocity of refrigerant, directly can reduce the striking speed of refrigerant to evaporimeter 3 inside, thus reduce the noise of refrigerant impact evaporimeter 3 generation, simultaneously, when reducing refrigerant striking speed, also reduce the refrigerant under liquid state, thus reduce the noise of liquid refrigerants impact evaporimeter 3 generation; Separately, the decay of coolant injection speed and weakening, can decrease the generation of refrigerant at the port of export turbulent flow of throttling transition conduit 2, and reduce further the noise of orifice union.
Based on above-mentioned, inner tubal wall flaring structure for throttling transition conduit 2 also needs to carry out preferably, and the impact of increaser on noise comprises two key elements: one is flaring angle, flaring angle is not be the bigger the better, flaring angle is crossed conference and is reduced impact refrigerant being run into velocity attenuation, therefore, flaring angle should control in rational angle, usual flaring angular range is less than 5 degree, be conducive to the tube wall that refrigerant first collides throttling transition conduit 2 in course of injection, and refrigerant also can make the tube wall of refrigerant multiple impacts throttling transition conduit 2, thus the jet velocity of refrigerant is decayed and weakens, two is pipe ranges, and throttling transition conduit 2 is longer, also more can decay and weaken the jet velocity of refrigerant.
Particularly, in this enforcement, as shown in Figure 3, throttling transition conduit 2 inner tubal wall is 3 degree in the flaring angle [alpha] at flaring place.
In the utility model, throttling transition conduit 2 can be stepless flaring, also can be multistage flaring; But stepless flaring and multistage flaring are contrasted, one, known based on above-mentioned two key elements, when flaring angle is identical, the length of the more stepless flaring of pipe range of multistage flaring, more be conducive to the jet velocity decaying and weaken refrigerant, and in process of production, multistage flaring can carry out multi-drawing according to required pole, produce also comparatively simple.In this enforcement, the inner tubal wall level Four flaring of throttling transition conduit 2 is arranged, specifically can see shown in Fig. 1 to Fig. 4, Fig. 1 is the structural representation of the utility model orifice union, Fig. 2 is the structure for amplifying schematic diagram of A in Fig. 1, Fig. 3 is the structure for amplifying schematic diagram of B in Fig. 1, and Fig. 4 is the structure for amplifying schematic diagram of C in Fig. 1.
Further, the inner tubal wall of throttle pipe 1 port of export is arranged along the flow direction flaring of tube fluid, and similarly, namely refrigerant has the function and efficacy of throttling transition conduit 2 from the port of export of throttle pipe 1, this specific works principle see also above-mentioned discussion, can not repeat them here.Similarly, based on above-mentioned discussion, the flaring angular range of the inner tubal wall of this throttle pipe 1 port of export is also less than 5 degree; Particularly, in this enforcement, as shown in Figure 6, throttle pipe 1 port of export is 3 degree at the flaring angle beta of the inner tubal wall at flaring place.
Separately, the inner tubal wall for throttle pipe 1 port of export is arranged along the flow direction flaring of tube fluid, is conducive to reducing throttle pipe 1 on the one hand and inserts in the process of throttling transition conduit 2 because shearing the burr formed, on the other hand, also can draw refrigerant scattering in, make refrigerant regular flow to, minimizing is uttered long and high-pitched sounds.
Further, throttle pipe 1 is encapsulated by quieter material with the junction of throttling transition conduit 2, this quieter material is the material that rubber damping block or silencing cotton etc. have absorbing acoustic damping characteristic, by the absorption of quieter material to partial noise, is conducive to the noise reducing orifice union on the whole.
Further, as shown in Figure 5, the pipe end that throttle pipe 1 is divided into multistage to connect successively, one end pipe end is wherein had at least to arrange in bending or bending, bending or the bending of this increase favourablely can slow down the flowing velocity of refrigerant in throttle pipe 1, thus reduce the jet velocity of refrigerant, thus reach the effect reducing noise; Concrete, in force, throttle pipe 1 is in the bending setting of the pipeline section at the 5cm place of the distance port of export.
The utility model also provides a kind of refrigerator, and comprise and connect successively and form the compressor of closed circuit, condenser, orifice union and evaporimeter, wherein, the structure of this orifice union can refer to above-described embodiment, does not repeat them here.Naturally, the refrigerator due to the present embodiment have employed the technical scheme of above-mentioned orifice union, and therefore this refrigerator has all beneficial effects of above-mentioned orifice union.
Further, be provided with device for drying and filtering between condenser and orifice union, this device for drying and filtering can moisture in suction line, to improve the purity of refrigerant in pipeline, thus improves the refrigerating efficiency of refrigerator.
Should be noted that; the technical scheme of each embodiment of the present utility model can be combined with each other; but must be can be embodied as basis with those skilled in the art; when technical scheme combination occur conflicting maybe cannot realize time people should think that the combination of this technical scheme does not exist, also not the utility model require protection domain within.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
