Description
Technical field
The present invention relates to a kind of flow mixing device, particularly a kind of gas-liquid two-phase flow mixing device.
Background technology
The temperature and pressure of evaporator outlet medium is the important parameter of reactive evaporation device performance, the refrigerant of traditional evaporimeter flow through into single current through or flow path less, and each flow path is longer, in heat transfer process, refrigerant can be thoroughly mixed to form single-phase superheated vapor to evaporimeter end, therefore directly can detect outlet medium temperature and pressure at evaporimeter end.
But the medium of existing evaporimeter flows through more, and each flow path is shorter, in the not high situation of the degree of superheat, evaporimeter end refrigerant can not evaporate completely, thus there will be evaporimeter outflow end gas-liquid two-phase refrigerant can not well-mixed problem, and the gaseous medium temperature that each flow path collects is inconsistent.
The gas-liquid two-phase refrigerant flowed out due to evaporimeter end can not fully mix, the medium stream temperature respectively flowing through outflow is inconsistent, still strong heat exchanging process is there is in refrigerant when test point position, system can not reach stable state, and therefore the temperature of existing evaporator outlet medium can not accurately be measured; Further, the refrigerant state of existing evaporimeter outflow end is invisible, and the setting assessment of the refrigerant state of outflow end to systematic function has decisive role; Therefore a kind of device accurately testing existing evaporator outlet medium temperature and pressure and observation evaporator outlet refrigerant state is needed.
Summary of the invention
In view of this, the object of this invention is to provide a kind of parallel-flow evaporator test flow mixing device, can not by the problem accurately measured with the temperature solving existing evaporator outlet medium.
Parallel-flow evaporator test flow mixing device of the present invention, the pipe joint comprise body, being tightly connected with body two ends, the heat-insulation layer being arranged at the copper wire suede obturator in body and being covered in outside body and pipe joint.
Further, described body is the transparent tube body be made up of acrylic material, and described pipe joint is the transparent pipe joint be made up of acrylic material, and described heat-insulation layer is provided with watch window.
Further, described copper wire suede obturator is made up of the copper wire that joint length is more than or equal to 200mm, cross section full-size is less than or equal to 1.0mm, and the density of described copper wire suede obturator is 0.5 ~ 1.0g/cm
3.
Further, described pipe joint retaining ring at body two ends, and is mutually permanently connected by bolt between two pipe joints, body is provided with the sealing ring of fit clearance between sealed fitting and body.
Beneficial effect of the present invention:
1, parallel-flow evaporator test flow mixing device of the present invention, its copper wire suede obturator specific area is large, space between copper wire is many, flow-disturbing effect is strong, thus the gaseous flow of different temperatures can be made, and biphase gas and liquid flow fully contacts mixing, liquid refrigerants is allowed fully to evaporate, can ensure that the refrigerant flowed out from the flow mixing device port of export is the gaseous state of single stable, under solving low overheat situation, biphase gas and liquid flow can not fully mix, and the measure error that evaporimeter outlet side different temperatures stratification of hot gas etc. causes, ensure that refrigerant temperature value measured by the flow mixing device port of export accurately and reliably.
2, parallel-flow evaporator test flow mixing device of the present invention, its body and pipe joint are outside equipped with heat-insulation layer, can stop refrigerant in body, with extraneous, heat exchange occurs, can further improve the accuracy of flow mixing device outlet refrigerant temperature.
3, parallel-flow evaporator test flow mixing device of the present invention, its body and pipe joint are transparent configuration, and heat-insulation layer is provided with watch window, thus the refrigerant state of evaporator outlet end can be observed, can be and provide important information to the setting assessment of evaporator system performance.
