The specific embodiment
Below with reference to accompanying drawing and combine embodiment to specify the utility model.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
As shown in Figure 1; The refrigeration system of present embodiment comprises compressor bank 1, condenser 2, device for drying and filtering 3, electric expansion valve 4, evaporimeter 5, the gas-liquid separator 6 that connects successively through refrigeration pipe; Also comprise sparge pipe 8, sparge pipe 8 is communicated with the refrigeration pipe of device for drying and filtering 3 ports of export and the refrigeration pipe of compressor bank 1 arrival end.The refrigeration pipe of device for drying and filtering 3 ports of export has the horizontally disposed straight length 7 of drawing.Sparge pipe 8 is positioned at draws straight length 7 belows, has and draws straight length 7 inclination straight length 81 that is welded to connect and the straight horizontal pipeline section that is connected with inclination straight length 81.Wherein, the angle theta between inclination straight length 81 and the horizontal plane is preferably between 30 to 60 °.Learn that through experimental verification from 30 to 60 ° of change procedures of the angle theta between inclination straight length 81 and the horizontal plane, the refrigerant flow resistance is corresponding to be reduced, welding process requirement is improved, reach the optimum value of combination property during 45 ° of left and right sides.Because sparge pipe 8 is positioned at the below of device for drying and filtering 3 export pipelines, and the coupling part of the two formation acute angle, angle preferably between 30 to 60 °, therefore promptly meets welding procedure, can reduce the bending of sparge pipe again, thereby has reduced the space that sparge pipe is arranged.This refrigeration system also helps the fixing of sparge pipe because bending is few.The downward-sloping flow resistance that also reduces refrigerant of sparge pipe.Owing to reduced the quantity of bending section, also effectively reduced the pressure drop in the sparge pipe.
Shown in Fig. 2 to 5, preferably, the center line of inclination straight length 81 intersects with the center line approximate vertical of drawing straight length 7 in the present embodiment.On drawing straight length 7, offer be connected with the straight length 81 that tilts be connected pore the time; On the intersection between the section of drawing straight length 7 at α=90 °-θ angle, seek the center of suitable location point drawing straight length 7 as punching; The center line that connects pore needs and this section approximate vertical, can realize that the center line of straight length 81 and the center line approximate vertical of drawing straight length 7 intersect.
In order to improve the operability of welding, connect pore and be preferably flange hole 71.The flange height in flange hole 71 can be set to 1.2 to 2.0mm, preferably is set to 1.4 to 1.6mm.
Like Fig. 2 and shown in Figure 5, the end face with drawing the link that straight length 7 is connected of inclination straight length 81 is positioned at the inside of drawing straight length 7.Stretch into the distance of drawing straight length 7 in order to control inclination straight length 81 rapidly and accurately, positioning convex point 82 is set at the link of inclination straight length 81.Preferably, the distance of the end face of positioning convex point 82 and link is between 4 to 10mm.
In the present embodiment, sparge pipe 8 is that specification is the copper pipe of φ 12 * 1 (unit is mm).The refrigeration pipe of device for drying and filtering 3 ports of export (comprise and draw straight length 7) is copper pipe, and is identical with the specification of device for drying and filtering 3 ports of export.The diameter of drawing the connection pore on the straight length 7 is 12.2mm.
The method of assembling between the refrigeration pipe of the sparge pipe 8 and device for drying and filtering 3 ports of export is following: the flange hole 71 on the straight length 7 is drawn in the link insertion of inclination straight length 81; Insertion depth leans on the positioning convex point 82 on the sparge pipe 8 to confirm; And guarantee the horizontal segment level of sparge pipe 8, afterwards with the link of sparge pipe 8 with draw straight length 7 and weld together.
From above description, can find out; The utility model the above embodiments have realized following technique effect: because sparge pipe is positioned at the below of device for drying and filtering export pipeline; And the coupling part of the two forms acute angle; Meet welding procedure, reduced the bending of sparge pipe, thereby reduced the space that sparge pipe is arranged.This refrigeration system also helps the fixing of sparge pipe because bending is few.The downward-sloping flow resistance that also reduces refrigerant of sparge pipe.Owing to reduced the quantity of bending section, also effectively reduced the pressure drop of refrigerant in sparge pipe.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
