Abstract
The invention provides a hot melt pipe fitting and belongs to the technical field of pipe fittings. The hot melt pipe fitting comprises a bearing section arranged at the end of the pipe fitting. The hot melt pipe fitting is characterized by further comprising a lining part arranged on the inner wall of the bearing section in a lining mode, and the outer wall of the lining part is closely attached to the inner wall of the bearing section. The hot melt pipe fitting has the advantages that due to the fact that the inner wall of the pipe fitting bearing part is supported by a metal lining, even if the hot melt time is properly prolonged, the pipe diameter of a pipe cannot be reduced in the hot melt connecting process, and the flow capability of the pipe fitting is ensured. Meanwhile, the connecting straightness between the pipe fitting and an accessory is ensured through the metal lining, the operation difficulty of an operator is lowered, and the requirement for the hot melt time is lowered; during hot melt connection, the pipe fitting bearing part is supported by the metal lining so that hot melt connection of the pipe fitting and the accessory can be tighter, and the connection strength of the pipe fitting and the accessory is improved.
Description
Technical field
The invention belongs to pipe fitting technical field, be particularly related to a kind of hot melt pipe fitting.
Background technique
Hot-melt adhesive paste is a kind of common pipe fitting Placement.Affect a lot of because have of pipe fitting quality of connection quality, such as: technology custom of the height of temperature, the quality of heat melting device, operator etc.After pipe fitting and accessory hot-melt adhesive paste, the carrier of pipe fitting is inserted in accessory inwall, and pipe fitting carrier is squeezed and caliber is diminished, and affects the through-current capability of pipe fitting.In addition, time long or too short upon reflow, the grazing that pipe fitting is connected with accessory is difficult to be guaranteed, and affects the quality of connection of pipe fitting.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect mentioned and deficiency, and a kind of hot melt pipe fitting is provided.
The technological scheme that the present invention realizes the employing of its object is as follows.
A kind of hot melt pipe fitting, comprises the undertaking section being arranged on this pipe fitting end, it is characterized in that, also comprises lining what accept section inwall and sets off part, described in set off part outer wall fit tightly with the inwall accepting section.
Described a kind of hot melt pipe fitting, is characterized in that, described in set off part and comprise cylinder ring in hollow cylinder, described cylinder ring with accept section interference fit.
Described a kind of hot melt pipe fitting, is characterized in that, described in set off part and comprise cylinder ring in hollow cylinder, described cylinder ring is bonding with undertaking section.
Described a kind of hot melt pipe fitting, is characterized in that, described in set off part and also comprise hollow disk ring, described disk ring is connected to the end of cylinder ring, and the internal diameter of disk ring is equal with cylinder ring internal diameter, and the external diameter of described disk ring is not more than the external diameter accepting section.
Described a kind of hot melt pipe fitting, is characterized in that, described disk ring fits in the end of accepting section.
Described a kind of hot melt pipe fitting, is characterized in that, described disk ring coordinates with the tip-clearance of accepting section.
This hot melt pipe fitting has following beneficial effect:
1., because the inwall of pipe fitting carrier obtains the support of metal lining, even if after hot molten time proper extension, tubing caliber in hot-melt adhesive paste process also can not be made to reduce, ensure that the through-current capability of pipe fitting.Meanwhile, metal lining ensure that and the straightness that pipe fitting is connected with accessory reduces the operation easier of operator, also reduces the requirement for hot molten time.
2. during hot-melt adhesive paste, pipe fitting carrier is subject to the support of metal lining, makes pipe fitting and accessory hot-melt adhesive paste more tight, improves both join strengths.
Accompanying drawing explanation
Fig. 1 is connection sectional view of the present invention;
In figure: accept section (100), set off part (200), cylinder ring (201), disk ring (202), accessory (300).
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of hot melt pipe fitting, comprises the undertaking section 100 that is arranged on pipe fitting end and lining what accept section 100 inwall and sets off part 200, described in set off part 200 outer wall fit tightly with the inwall accepting section 100.
The described part 200 that sets off comprises cylinder ring 201 in hollow cylinder.As preferably, described cylinder ring 201 with accept section 100 interference fit, ensure that the join strength setting off part 200 and accept section 100; Preferred as another kind, described cylinder ring 201 is bonding with undertaking section 100.Cylinder ring 201 is fitted and is accepted the inwall of section 100.When hot-melt adhesive paste, cylinder ring 201 is accept section 100 to provide outside support force, avoids undertaking section 100 on the one hand and under the extruding of accessory 300, caliber is diminished, also improve the join strength accepting section 100 and accessory 300 on the other hand.
The described part 200 that sets off also comprises hollow disk ring 202.Described disk ring 202 is connected to the end of cylinder ring 201, and the internal diameter of disk ring 202 is equal with cylinder ring 201 internal diameter.The external diameter of described disk ring 202 is not more than the external diameter accepting section 100.As preferably, described disk ring 202 fits in the end of accepting section 100.Accept section 100 when hot melt, volume can change, the setting of disk ring 202, provides the support of side direction for accepting section 100, makes to accept section 100 density when hot melt and more compacts.Preferred as another kind, described disk ring 202 coordinates with the tip-clearance of accepting section 100, when the internal diameter of accessory is too small, accept section 100 external diameter when hot melt to reduce with the internal diameter adapting to accessory, accept outside section 100 end and move, therefore, disk ring 202 is accept to move outside section 100 end to provide surplus with accepting that the tip-clearance of section 100 coordinates, adds the applicability of this hot melt pipe fitting.
As preferably, described cylinder ring 201 and disk ring 202 are wholely set, and ensure that both join strengths.
Adopt the hot melt pipe fitting of this structure, can improve the welding speed of hot melt pipe fitting, ensure normal flow rate required by caliber, cost of production is low, and solves pipe fitting and be out of shape the difficult problem that caliber is diminished when hot melt.
The present invention is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technological scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection scope of the present invention.
