Abstract
The invention discloses a reducing bellows joint without joints, including a main tube the two ends of a middle section pipe of which are symmetric and combined in sections, a reducing tube and a tube end. The outer end of the main tube is transited and shrunken into the tube end by the reducing tube; the other end of the main tube is also transited and shrunken into a middle joint tube by the reducing tube. The wall of the middle section tube of the main tube forms a rib structure by the coaxial spiral ripple that is inwards concave. The tube body of the invention is integrated with no welding joints and no hidden leakage troubles of joints. The caliber of the main tube is large and is provided with the rib structure; the cavity of the tube is not deformed when being bent; the circulation resistance for a medium is small. The reducing bellows joint without joints is suitable for being used as the connection tube for the indoor machine set and the outdoor machine set of a separated air conditioner and a hydraulic system.
Description
Technical field
The present invention relates to a kind of reducing connecting tube, particularly a kind of reducing endless corrugated connecting tube.
Background technique
Detachable air conditioner is a kind of very universal household electric appliance, and its indoor units is connected by connecting tube realization system with outdoor unit.The connecting tube typical structure of prior art is isometrical pipe, and its caliber is identical with the pipe of joining compressor conveying refrigerant.Machine structural limitations by compression, the connecting tube caliber of prior art is thin partially, and structural strength is low, and when wiring connected, one section particularly through walls easily was out of shape by bending and reduces the circulation of refrigerant in the pipe.At present, existing a kind of reducing connecting tube is fitted on the detachable air conditioner in the industry, and thick slightly one section is seated in easily by the bending deformation place, and this structure connecting tube has effectively overcome the shortcoming and defect of isometrical pipe, has significant technique effect.But, the welding method that adopts prior art reducing connecting tube realizes that the pipe of different tube diameters connects, welded joint has leakage hidden danger, and when welding the scale that produces of pipe joint inwall be difficult for removing, scale comes off and sneaks into wherein under the impact of refrigerant stream, easily stops up refrigeration system and causes the accident.
Summary of the invention
The present invention is primarily aimed at the deficiencies in the prior art, proposes a kind of integrated reducer segmental structure, does not have the trouble of structure leakage, and is easy to manufacture, but pipeline bending but the indeformable reducing endless corrugated connecting tube of tube chamber.
Reducing endless corrugated connecting tube of the present invention, it comprises the conjuncted person in charge, reducer pipe and the pipe end of stage casing pipe two ends symmetry segmentation.Its improvements are: described person in charge outer end dwindles into pipe end by the reducer pipe transition, is responsible for the other end and dwindles by the reducer pipe transition equally between the middle adapter.Described person in charge stage casing outer wall constitutes rib structure by the axial screw ripple of indent.
The pipe thickness of the person in charge in the said structure, reducer pipe and pipe end and middle adapter is identical.Reducer pipe is by R8～30mm arc transition reducing, its Outside diameter 〉=16≤50mm, small end 〉=8≤35mm.The axial screw ripple of being responsible for stage casing tube wall indent is 1～6, the ripple indent degree of depth 1.6～5.0mm, and pitch is 2.0～8.0mm.The axial screw ripple constitutes the rib structure of being responsible for outer wall, significantly improves main drive tube to non-deformability, does not change charge shaft to flexible performance.
The present invention compared with prior art has following good effect:
1, be responsible for by the transition of reducer pipe nature and dwindle into pipe end or middle adapter, the body of conjuncted structure, the sorrow of non-joint leakages, need not weld to have the come off hidden danger of pollution medium of the interior scale of pipe;
2, reducer pipe is by circular arc nature transition reducing, and the liquid resistance is little;
3, be responsible for the axial screw ripple that tube wall is provided with indent, the axial screw ripple constitutes rib structure, significantly improves main drive tube to non-deformability, does not change charge shaft to flexible performance.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is elaborated.
Embodiment 1
Reducing endless corrugated connecting tube shown in the drawings is taken over the conjuncted person in charge 1, reducer pipe 2 and the pipe end 3 of 4 two ends symmetry segmentation during it comprises.The described person in charge 1 outer end dwindles into pipe end 3 by the reducer pipe transition, is responsible for 1 the other end and dwindles by reducer pipe 2 transition equally between the middle adapter 4.The described person in charge's 1 stage casing tube wall constitutes rib structure by the axial screw ripple 1.1 of indent.Present embodiment is to be used for the reducing endless corrugated connecting tube that 3 detachable air conditioner indoor and outdoor units are connected, be responsible for the copper tube of 1 usefulness φ 24mm and make raw material, at the axial screw ripple 1.1 of being responsible for 2 indent 2.4mm of spinning on the 1 stage casing outer wall, the pitch of helical corrugation 1.1 is 3.5mm.Be responsible for 1 the other end between the middle adapter 4, the R8mm arc transition by reducer pipe 2 dwindles into middle adapter 4 equally.The diameter of pipe end 3 and middle adapter 4 is φ 16mm.The present invention is a kind of pipeline of conjuncted structure, although each section caliber does not wait, non-joint and wall thickness equate between each section, be responsible for the axial screw ripple 1.1 that 1 tube wall is provided with indent in addition, axial screw ripple 1.1 constitutes the rib structure of being responsible for 1 outer wall, significantly improve radially non-deformability of the person in charge 1, do not change and be responsible for 1 axial flexible performance.The body of the conjuncted structure of the present invention does not have the sorrow of leakage, and need not weld to have the interior scale of pipe to come off to the sorrow of medium pollution.
Embodiment 2
Present embodiment is the φ 27mm connecting tube that is applied in the 200T oil hydraulic press hydraulic system, its structure is identical with embodiment 1, and the person in charge's 1 caliber of red copper matter is φ 50mm, is responsible for 1 stage casing outer wall and is provided with 6 axial screw ripples 1.1, the pitch of axial screw ripple 1.1 is 6mm, and the indent degree of depth is 5.0mm.Be responsible for 1 two ends and become φ 27mm pipe end 3 and middle adapter 4 by the R20mm arc transition of reducer pipe 2 respectively.The technique effect of present embodiment is identical with embodiment 1.
Each segment length is unrestricted among the present invention, can make as required.
