Description

A kind of Thin-wall Tube joint
Technical field
The utility model relates to a kind of pipe joint, especially relates to the pipe joint technical field that is used to connect thin walled tube.
Background technique
Usually the pipe of wall thickness below 1mm is called thin walled tube, and thin walled tube generally adopts stainless steel or copper material to make, it is compared with traditional iron pipe has not polluted water, can resist the infringement of acid and alkali substance to pipeline, therefore the stainless steel pipe uses more and more extensive in resident's family, replace the use of galvanized pipe gradually, be connected with thin walled tube so thin walled tube occurred, need thin walled tube to be connected again simultaneously with thick walled tube.It is many that traditional Bite type fittings generally is fit to similar aluminium-plastic composite pipe flexible tube, also there is suitable thin-wall stainless steel pipe to connect, but can be fit to simultaneously thin walled tube be connected with thin walled tube with thin walled tube be connected with thick walled tube rare, and the use of general this pipe joint, need special instrument to cooperate, as expander caliber instrument, operated pressing tool or the like.Chinese patent also has certain bibliographical information to the technology that the thin walled tube joint connects, as the patent No. 96211525.8 " thin walled tube combination fitting ", it is by the swivel nut that is spirally connected mutually, nut, " O " RunddichtringO between the lining of a public band omoplate and lining omoplate and the pipe enlarging is formed, by screwing swivel nut, nut makes enlarging distortion press to " O " RunddichtringO and be close to and forms on the lining omoplate not only firmly but also the connection of sealing, solved the connectivity problem of thin walled tube, replace galvanized pipe with stainless-steel thin-wall pipe and eliminated the existing many disadvantages of former galvanized pipe, also have long service life, in light weight, specious, advantage such as clean and tidy.It no doubt has the progressive meaning of its description, but also have some blemisies in an otherwise perfect thing, can obtain sealing effect in order to make the lining omoplate, the bore of butt tube will carry out hole enlargement to be handled, need to be equipped with special expanding tool, also increased Connection Step, in connection procedure, tube joint assembly need be enclosed within the joining part of two adapters simultaneously in addition, connect, operation is not that easily so Placement is simple inadequately, further improvement need be done in these aspects.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of suitable thin walled tube and thin walled tube, thin walled tube to be connected, to connect quick and convenient firm, the difficult loosening Thin-wall Tube joint of revealing with thick walled tube at prior art.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this kind Thin-wall Tube joint, it includes pipe joint body, nut, the interface position system outside thread of body, there is the nut of system internal thread to be threaded simultaneously with the interface of body, it is characterized in that: the interface inboard of body is shaped on conical surface, has simultaneously to be enclosed within to take over oral area and the metallic seal cutting ferrule of position between body interface and nut.
Above-mentioned body has the socket retaining that inserts for the thin walled tube end in the interface the inside.
The inclined-plane angle of above-mentioned conical surface is between the 10-20 degree.
Its front bulkhead attenuate of above-mentioned metallic seal cutting ferrule, the aft bulkhead thickening, the inclined-plane in tail end end face and the nut mates.
Above-mentioned adapter oral area inner liner metal is reinforced lining.
Compared with prior art, advantage of the present utility model is: 1 connection is quick and convenient, not needing the specialist tools butt tube will carry out hole enlargement handles, step has been lacked, and do not need to be enclosed within simultaneously the oral area of two adapters at connection procedure yet, as long as connect one by one just passable, so connect quick and convenient; 2, be connected firmly, be not easy loosening the leakage, because adopt metallic seal cutting ferrule spare, its front end is subjected to being out of shape behind the certain pressure, the outer surface that anchor ear lives to take over, even be embedded in the outer surface of adapter, so good seal performance is connected firmly, be not easy loosening the leakage; 3, compressive strength height, long service life, because adopt metallic seal cutting ferrule spare, good sealing effect, so the compressive strength height, long service life; 4, be fit to thin walled tube and be connected with thick walled tube, reduce the pipeline link cost, be convenient to it and promote the use of with thin walled tube, thin walled tube.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model is described in further detail.
Embodiment 1, as Fig. 2-4 signal, this is a kind of pipe joint of through-type structure, it includes pipe joint body 1, nut 2, body adopts thick walled tube directly to make, at its interface position 11 outer surface system outside threads 12, be shaped on conical surface 13 in the interface inboard, the inclined-plane angle of conical surface is controlled between the 10-20 degree, simultaneously taking over the end for convenience positions fixing in the interface of joint body, be shaped on the socket retaining 14 that inserts for the thin walled tube end in interface conical surface the inside, its length control 10-15mm.Other has to be enclosed within and takes over oral area and the metallic seal cutting ferrule 3 of position between body interface and nut, its front bulkhead attenuate, the aft bulkhead thickening, inclined-plane 22 in tail end end face and the nut mates, make things convenient for nut that the jacking of metallic seal cutting ferrule is gone like this, also make its front end distortion easily, thereby anchor ear is firmly taken over 4 outer surface.Metallic seal cutting ferrule front end has the gear 31 that reduces wall thickness, and it can be the toroidal surface of inclined-plane or its wall thickness of attenuate.Other has the nut 2 of system internal thread 21, and it is threaded with the interface of body.Generally for the thin-walled tube of diameter-wall-rate; need not lining metal in the oral area that thin-walled is taken over and reinforce lining;; can reinforce lining 5 by lining metal in the oral area that thin-walled is taken over; the length of lining is advisable, and the diameter of its diameter and adapter will mate about 20mm for the thin-walled tube of diameter-wall-rate greater than 1: 35 less than 1: 35.The body of whole pipe joint adopts thick walled tube to process.Whole pipe joint can adopt stainless steel material or copper material to manufacture.
Its using method and principle are as follows, the oral area of taking at thin-walled is inserted in nut and metallic seal cutting ferrule successively, then the end of taking over is inserted in the joining part of pipe joint body, be threaded with the interface of pipe joint with nut, as long as progressively screw nut, just the jacking of metallic seal cutting ferrule is gone, because the front end of metallic seal cutting ferrule is under the conical surface compressing of body, generation is to internal strain, anchor ear is lived the surface of thin walled tube gradually, might make it that certain interior compression deformation also takes place, reach the effect of sealing.Can reinforce lining by first inner liner metal for bigbore thin walled tube, at this moment, the front end of metallic seal cutting ferrule takes place to internal strain under the conical surface compressing of body, and anchor ear is lived the surface of thin walled tube gradually, and is embedded in the surface of adapter, reaches the effect of sealing.
Embodiment 2, as schematically shown in Figure 5, this pipe joint is the three-way type structure, interface position 11 adopts metal tube to make, be welded on then on the three-way pipe that the sheet metal drawing and forming forms, as as described in the embodiment 1, class siphonal pipe joint, reduced tee pipe joint also can be made like this and form about its structural principle and using method.
