Description
Technical field
The utility model relates to refrigeration system equipment, particularly a kind of cylindrical shell of the gas-liquid separator that is used for refrigeration system and the syndeton between the outgoing gas connection tube.
Background technology
In general, gas-liquid separator is arranged between the air entry and evaporimeter of compressor, is used for the gas-liquid biphasic mixture that separating evaporator discharges, and prevents that liquid refrigerant from directly getting into compressor and producing liquid hammer.As illustrated in fig. 1 and 2; Existing a kind of gas-liquid separator comprises the cylindrical shell 01 of liquid storage and is located at the outgoing gas connection tube 02 in the cylindrical shell, and the escape pipe 03 that is connected with outgoing gas connection tube; On cylindrical shell, be provided with necking end 011; Outgoing gas connection tube is provided with flared end 021 and is connected with necking end, on the flared end of outgoing gas connection tube, is provided with axial convex tendon 022 and fits with the inwall of necking end, and escape pipe and flared end directly are connected.Such structure makes cylindrical shell and outgoing gas connection tube fit clearance big because convex tendon is set on outgoing gas connection tube, and the scolder consumption is more during welding, and fit clearance is bigger simultaneously, and the failure welding rate is also higher relatively; And escape pipe and flared end directly are connected, and scolder is difficult to get into the weld seam between escape pipe outer wall and the flared end inwall during welding, causes the scolder poor permeability, and the failure welding rate increases, and the outside fluid capacitance of scolder is prone to cause fluid welding in addition, has a strong impact on product appearance.
The utility model content
The utility model problem to be solved just provides a kind of gas-liquid separator and improves structure, and is simple in structure, easy to make, practiced thrift scolder and weld interval, and the fluid welding fraction defective is also reduced greatly, reduced production cost, promoted properties of product and outward appearance.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of gas-liquid separator improves structure; Comprise the cylindrical shell of liquid storage and be located at the outgoing gas connection tube in the cylindrical shell, and the escape pipe that is connected with outgoing gas connection tube, necking end on cylindrical shell, be provided with; Outgoing gas connection tube is provided with flared end; It is characterized in that: the inner and inner interference fit of flared end outer wall of said necking end inwall, be provided with ventilative gap between flared end outer wall outer end and the necking end inwall outer end, on flared end, be provided with the air-vent that at least one is communicated with ventilative gap.
Further, said necking end inwall outer end is provided with the first step section that internal diameter increases, and said ventilative gap is the space between first step section and the flared end outer wall outer end.
Further, said flared end outer wall outer end is provided with the second step section of reduced diameter, and said ventilative gap is the space between second step section and the necking end inwall outer end.
Further, be provided with chamfering between the outer face of said necking end and the necking end inwall.Make scolder form the guide effect of in weld seam, flowing, owing to cancelled end face, make the not firm phenomenon of end face welding be able to eliminate simultaneously, the failure welding rate is further descended again.
Further, the flared end matched in clearance of said escape pipe and outgoing gas connection tube.Be convenient to scolder and flow between escape pipe and the flared end, improve the permeability of scolder.
After adopting technique scheme; The utlity model has following advantage: outgoing gas connection tube cooperates with adopting inner interference fit gap of outer end cooperating of cylindrical shell; Interference fit does not come off outgoing gas connection tube, the air-vent mating reaction of step section and outgoing gas connection tube flared end, and the gas when welding between outgoing gas connection tube and cylindrical shell can be overflowed; Thereby can not overflow and cause the pore phenomenon, guarantee the permeability of scolder simultaneously yet because of gas.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of existing a kind of gas-liquid separator;
Fig. 2 is the cross sectional view of the flared end of existing outgoing gas connection tube;
Fig. 3 is the structural representation of a kind of embodiment of the utility model;
Fig. 4 is an I place enlarged drawing among Fig. 3.
The specific embodiment
The structural representation of a kind of embodiment of the utility model shown in Fig. 3 and 4; A kind of gas-liquid separator improves structure; Comprise the cylindrical shell 1 of liquid storage and be located at the outgoing gas connection tube 2 in the cylindrical shell, and the escape pipe 3 that is connected with outgoing gas connection tube, necking end 11 on cylindrical shell, be provided with; Outgoing gas connection tube is provided with flared end 21; Inner and the inner interference fit of flared end outer wall of said necking end inwall is provided with ventilative gap 12 between flared end outer wall outer end and the necking end inwall outer end, on flared end, be provided with the air-vent 22 that at least one is communicated with ventilative gap.In the present embodiment, on necking end inwall outer end, be provided with the first step section that internal diameter increases, said ventilative gap is the space between first step section and the flared end outer wall outer end.
In the foregoing description, between the outer face of necking end and necking end inwall, be provided with chamfering 13.In addition, the flared end matched in clearance of escape pipe and outgoing gas connection tube.And the step section also can be arranged on the flared end outer wall; Be specially the second step section that on flared end outer wall outer end, is provided with reduced diameter; Ventilative like this gap is exactly the space between second step section and the necking end inwall outer end; Be the difficulty of processing that such structure can increase flared end, make the thickness attenuation of flared end, influence its intensity.
The outgoing gas connection tube of the utility model cooperates with adopting inner interference fit gap of outer end cooperating of cylindrical shell; Interference fit does not come off outgoing gas connection tube; The air-vent mating reaction of step section and outgoing gas connection tube flared end; Gas when welding between outgoing gas connection tube and cylindrical shell can be overflowed, and does not cause the pore phenomenon thereby can not overflow because of gas, has also guaranteed the permeability of scolder simultaneously; Said cylindrical shell necking end is provided with interior chamfering, makes scolder form the guide effect of in weld seam, flowing, owing to cancelled end face, makes the not firm phenomenon of end face welding be able to eliminate simultaneously, and the failure welding rate is further descended again.In the utility model, the fit clearance between escape pipe and outgoing gas connection tube and outgoing gas connection tube and cylindrical shell is little, has practiced thrift scolder, and shortened weld interval greatly, and adopts chamfering that the fluid welding fraction defective is also reduced greatly, has reduced cost, has promoted properties of product and outward appearance.
Except that above-mentioned preferred embodiment; The utility model also has other embodiment; Those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from the spirit of the utility model, all should belong to the defined scope of the utility model accompanying claims.
