Abstract
An internal and external machine connecting pipe double layer flaring joint in an air conditioner room comprises a connecting pipe body, an interface of which is designed into a bell mouth shape, and the pipe wall of the interface is in double layer structure. For the double layer flaring is adopted by the utility model, the interface of the connecting pipe is turned over inward for certain length at first, and then being expanded into a bell mouth in required angle. The flaring section is in double layer wall thickness. The intensity of a contact area is increased, the bearable compressive force is enlarged and the sealing reliability is enhanced. For the contact area is double layer and the interlayer has certain elastic force, the bell mouth is not easily damaged; moreover, for certain energy is stored, the sealing performance is greatly improved.
Description
Technical field
The utility model belongs to the manufacturing technology field, is specifically related to the double-deck enlarging structure of a kind of air conditioner indoor unit and outdoor unit connecting tube mouth of pipe.
Background technique
At present, air conditioner indoor unit and outdoor unit connecting tube is selected copper tube mostly for use, and this copper tube end-fitting adopts individual layer enlarging form.The copper tube two ends are connected with the air conditioner indoor unit and outdoor unit respectively by pipe joint.Charge into refrigeration agent in the pipe-line system, the vaporization circulation in pipeline of the compressed machine compression of refrigeration agent back.Refrigeration agent is the gas highly volatile under nature, certain pressure is arranged in pipeline, if connecting tube expanding end inner conical surface and the applying of pipe joint male cone (strobilus masculinus) is bad, the applying impacting force not enough, the expansion mouth bit loss is bad etc. all can cause freezing medium leakage, thereby loses the air conditioner function.Individual layer enlarging intensity is lower, and the necessary suitable screwing force of tube Female connector fittings makes pipe enlarging contact area that certain elasticity and plastic deformation be arranged, and reaches tight effect.Screwing force too small poorly sealed, thereby the excessive enlarging of screwing force position easily cracks etc. causes freezing medium leakage.On July 25th, 2007, " China Quality Newspaper Office " Chinese household electrical appliances research institute one expert said: because improper causing is installed, this also illustrates the significance of connecting tube joint and correct installation to air conditioner leakage fluorine more than 99%.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide a kind of intensity big, interlayer has certain elastic force, make horn mouth not fragile, laid in certain energy again, make the double-deck flare type joint of air conditioner indoor unit and outdoor unit connecting tube that sealing improves greatly.
For achieving the above object, the technical solution adopted in the utility model is: the double-deck flare type joint of a kind of air conditioner indoor unit and outdoor unit connecting tube, comprise the connecting tube body, and the Interface design of this connecting tube body is the horn mouth shape, and the tube wall of interface is a double layer construction.
Because the utility model adopts double-deck enlarging structure, the connecting tube jointing is at first turned down certain-length in pipe, expand into the horn mouth of required angle again.The enlarging position is double-deck wall thickness.Contact area intensity is increased, can bear bigger extruding force, seal more reliable.The contact area is double-deck, and interlayer has certain elastic force, make horn mouth not fragile, laid in certain energy again, sealing is improved greatly, reduced installation requirement, thoroughly solve the fluorine problem of leaking.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model;
Fig. 2 installs connection diagram for the utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are described in further detail.
The utility model comprises connecting tube body 1, and the interface 2 of this connecting tube body 1 is designed to the horn mouth shape, and the tube wall 3 of interface 2 is a double layer construction.
When making with connecting tube body 1 on the multi-position flaring machine, with the inside flat double layer constructions that form of turnover certain-length piers of interface 2, again interface 2 is expanded into the horn mouth shape earlier.The bell-mouthed angle of interface 2 can be made any size as requested.
Intercept the connecting tube body 1 of specific length during use on request, the termination equating chamfering of connecting tube body 1.Pipe joint nut 4 is inserted at two ends, on the multi-position flaring machine double-deck enlarging is carried out at two ends, forms Fig. 1 structure.When air conditioner is installed, be that the double-deck connecting tube body 1 of horn mouth shape is connected with the pipe joint 5 of indoor unit and outdoor unit respectively by pipe joint nut 4 and tightens with joint, pipe joint nut 4 inner conical surfaces fit tightly the double-deck horn mouth of connecting tube body 1 with pipe joint 5 male cone (strobilus masculinus)s, thereby play the inside and outside machine refrigerant circulatory system of air conditioner chamber is communicated with and airtight effect.Realize the air conditioner function.
