Description
Technical field
The utility model relates to a kind of pipe connecting component, particularly a kind of can be with the link of pipeline crimping.
Background technique
During the pipeline Placement had a lot, traditional Placement was as being threaded, and cost of production is too high, and manufacturing efficiency is low.Chinese patent CN2510705Y has announced a kind of clamp-press type metal pipe element, after this pipe fitting is pressed through pincers, realize being tightly connected, but the installation of this pipe fitting has higher code requirement, and it is also not really desirable to connect effect, and cost is than higher.
The model utility content
The purpose of this utility model provides a kind of crimping pipe fitting, and it is undesirable that the utility model has solved the connection effect that existing connection pipe fitting exists, the problem that cost is high.
A kind of crimping pipe fitting of the present utility model is made of pipe fitting, tubing, Sealing and annular pressure pad; In the port of pipe fitting, from compressing hole, closed hole and socket joint positioning hole are arranged outside to inside successively; The diameter of bore size of compressing hole, closed hole, socket joint positioning hole and pipe fitting reduces gradually successively and forms three grades of stepped bore; The end of tubing is inserted in the inner step place of socket joint positioning hole; Sealing is positioned at closed hole and the inboard place of compressing hole; The annular pressure pad is positioned at the port of compressing hole; At socket joint positioning hole and pipe fitting end opposite position place the annular indent that forms by the crimping tool crimping is arranged.
A kind of crimping pipe fitting of the present utility model can also have following characteristics: the contraction mouth that the external port place of compressing hole has inside compression to form.
A kind of crimping pipe fitting of the present utility model has improved the connection effect greatly, and sealing reliability, and cost is low, and is simple in structure, and it is fast to produce installation efficiency.

Embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Consult Fig. 1-Fig. 6, a kind of crimping pipe fitting is made of pipe fitting 1, tubing 2, Sealing 3 and annular pressure pad 4; In the port of pipe fitting 1, from compressing hole 1-1, closed hole 1-2 and socket joint positioning hole 1-3 are arranged outside to inside successively; The diameter of bore size of compressing hole 1-1, closed hole 1-2, socket joint positioning hole 1-3 and pipe fitting 1 reduces gradually successively and forms three grades of stepped bore; The end of tubing 2 is inserted in the inner step place of socket joint positioning hole 1-3; Sealing 3 is positioned at closed hole 1-2 and the inboard place of compressing hole 1-1; Annular pressure pad 4 is positioned at the port of compressing hole 1-1; At socket joint positioning hole 1-3 and opposite position place, pipe fitting 1 end the annular indent 6 that forms by crimping tool 5 crimping is arranged.The contraction mouth 7 that the external port place of compressing hole 1-1 has inside compression to form.
A kind of crimping pipe fitting of the present utility model is by pipe fitting, lip ring and annular pressure pad, and connect the tubing composition.Pipe fitting is provided with the socket joint positioning hole, closed hole and compressing hole, form step hole, ring-like Sealing is contained in successively to be connected with ring-like pressure pad and inserts pipe fitting socket joint positioning hole on the tubing respectively, in closed hole and the compressing hole, utilize special-purpose crimping tool connection pipe fitting and tubing, at crimping pipe fitting socket joint positioning hole, in the time of closed hole and compressing hole cylindrical, compression connects tubing.Compress and connect in the tubing process, make the pipe fitting closed hole compress lip ring, annular pressure pad is pushed in the compressive strain of pipe fitting compressing hole cylindrical end face, annular pressure pad compression lip ring, compressing hole cylindrical end face compressive deformation, form closing in locking lip ring and annular pressure pad, play radial and axial two way sealed, reach sealing and be connected effect.Pipe fitting is consistent with link connection joint, back and crimping tool pressing mold shape chamber size and dimension.
Pipe fitting is provided with the socket joint positioning hole, closed hole and compressing hole respectively be connected tubing, ring-like Sealing and ring-like pressure pad sectional shape and size are fitted to each other.Pipe fitting is provided with the socket joint positioning hole, and the sectional shape of closed hole and compressing hole can be shapes such as stepped shape, taper.
Ring-like Sealing sectional shape can be a stepped shape, other shape such as taper.
Ring-like pressure pad sectional shape can be taper, and is square, and circle waits other shape.
Ring-like pressure pad adopts materials such as stainless steel, and ring-like Sealing adopts Ethylene Propylene Terpolymer, and silicone rubber waits material.
Crimping tool pressing mold shape cavity shape can be a Hexagon, other shape such as Octagon.
Ring-like pressure pad can be to be slidingly connected when being connected the tubing suit, and fixedlys connected two kinds.Fixedly connected can be Placements such as welding or riveted joint.
