Abstract
The utility model relates to a kind of variable-diameter corrugated pipe assembly, comprise supervisor, described supervisor middle part is provided with reducer pipe, outside described reducer pipe, cover has thermal insulation pipe, reducer pipe two ends are connected with bellows respectively, and described bellows straight tube port is connected with reducing pipe, reducer pipe and reducing pipe equal diameters, described reducing pipe is provided with locking nut, and reducing pipe port is provided with horn mouth.There is following advantage in the variable-diameter corrugated pipe assembly that the utility model provides: the variable-diameter corrugated pipe group assembly property that the utility model provides is excellent, and compressive strength is high, and pipe inside and outside wall light after tube reducing, even tissue, good mechanical performance.
Description
Technical field
The utility model relates to a kind of bellows, particularly relates to a kind of variable-diameter corrugated pipe assembly, belongs to air conditioner parts technical field.
Background technique
Producer installed by domestic and international air-conditioning all needs to use bellows to indoor set and outdoor unit installation, generally use isometrical bellows and variable-diameter corrugated pipe, and more can adapt to the demand of complicated installation environment due to variable-diameter corrugated pipe, its application percentage increases increasingly, slowly replaces isometrical bellows.The structure of variable-diameter corrugated pipe is pipe two ends is ripple large-diameter pipe, and intermediate portion is small diameter tube, and two ends is the small diameter tube identical with mid diameter.
The variable-diameter corrugated pipe of prior art mainly adopts traditional undergauge and two ends expanding technology to make, tradition diameter reducing process is by extrusion forming mold shaped by fluid pressure, due to the restriction of forming die length, be not suitable for extruding long tube, and inner tube wall easily forms the situation of fold and wall unevenness owing to extruding undergauge, thus influential system performance, and the implementation procedure of two ends expanding technology advances expanding by pipe inner core rod as support rotation, because plug is by gripping apparatus grips High Rotation Speed, its length is longer, beating of producing is larger, this beats and directly causes thickness of pipe wall uneven, the ripple forming quality of the lower step of impact, the final total quality affecting bellows.
Model utility content
The utility model, for the deficiency of existing variable-diameter corrugated pipe, provides a kind of Novel diameter reducing bellows component.
The technological scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of variable-diameter corrugated pipe assembly, comprise supervisor, described supervisor middle part is provided with reducer pipe, outside described reducer pipe, cover has thermal insulation pipe, reducer pipe two ends are connected with bellows respectively, and described bellows straight tube port is connected with reducing pipe, reducing pipe and reducer pipe equal diameters, described reducing pipe is provided with locking nut, and reducing pipe port is provided with horn mouth.
The beneficial effects of the utility model are: the variable-diameter corrugated pipe assembly property that the utility model provides is excellent, and compressive strength is high, and pipe inside and outside wall light after tube reducing, even tissue, good mechanical performance.。
On the basis of technique scheme, the present invention can also do following improvement.
Further, described bell-mouthed flaring angle is 90 °.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model bellows component;
